Optical Sorters Ultimate Buying Guide
First off, we’ll show you why you should consider using optical sorters as opposed to the traditional sorting methods. Next, we’ll talk about how these devices work, and finally, we’ll help you select the best optical sorter suited to your needs.
Let us begin:
What is an Optical Sorter?
1.1 What is an optical Sorter
You’ve probably heard a lot about optical sorting, but you aren’t sure what it is and how it can be beneficial to you. If so, then you have come to the right place. Optical sorting, sometimes referred to as digital sorting is an automatic process of sorting solid products using cameras and/ or lasers. The device uses a software-driven image processing system that is able to identify objects size, shape, color, chemical composition, and structural properties. All you need to do is input your preferred accept/ reject criteria in the device, and the sorter will compare the objects and remove any defective products and other foreign materials from the product line. Additionally, you can program the sorter to separate products of different types of materials or grades. The applications for the use of an optical sorting machine are numerous. One of the largest application areas is the food industry where the sorter can be used to process harvested foods including vegetables, nuts, fruits, potatoes, and much more. In addition, the technology has also been adopted by other industries for:
- Waste recycling
- Nutraceutical manufacturing
- Pharmaceutical manufacturing
- Tobacco processing, and more
In short, an optical sorter uses light and sensors to capture images of the objects for processing and removes any impurities such as unwanted rot, greening defects, blemishes, damage, and foreign material such as stones, metal, or glass from the product line.
1.2 Benefits of Using a Color Sorting Machine
A color sorter machine will drive down labor costs, increase quality, and even increase the performance and production speed. Here are the benefits of using a color sorter machine:
When it comes to marketing products, the presentation is critical.
Since the color sorting machines are automated, they can continue selecting and dispersing of products for hours on end.
Return on Investment (ROI) is one of the most useful decision-making tools.
Reduced Labor Costs
An advanced sorting machine can inspect millions of individual product pieces per hour.
1.3 Why You Should Use an Optical Sorter
From a marketing and advertising point of view, how your product appeals to potential clients can be a huge determinant of your expected profits.
How Optical Sorter Works
A sorter’s performance depends on the application, the characteristics of the products, and the user’s objectives. An optical sorter comprises of four main components namely:
2.1 Machine Identification Process
Now that we’ve highlighted the four main components of an optical sorting machine let’s break the sorting process down. The first step is the identification process.
2.2 Machine Ejection Process
Now that we’ve covered how the device identifies the material, let’s take a closer look into how the ‘good’ and ‘bad’ materials are ejected from the product line.
The ejector system is the location where the particulate matter falling from the end of the conveyer belt is detected at a predetermined position, and based on this detection, that particular matter is eliminated by air.
- Standard valves – These are the most common types. They are used for foods, plastics, and other small pieces/ materials.
- Heavy duty valves – They are mainly used for heavier and bigger pieces such as large chunks of wood.
When defaulted materials are being ejected, they can be directed in two ways:
- Upward ejection – https://www.youtube.com/watch?v=O0gWUeqzk_o
- Downward ejection – https://www.youtube.com/watch?v=vbSww5SBqN4
The upward ejection process works by redirecting the selected product (the bad material) in an upward and outward manner in the ejection chute.
Pros and Cons of Upward and Downward Ejection Process
Each of these ejection set-ups comes with their own advantages and disadvantages.
2.3 Factors to Evaluate the Quality of the Optical Sorter
As earlier mentioned, sorting systems can rapidly detect and physically remove any contaminated objects from your product line.
- What am I trying to achieve?
- What are the business risks of doing nothing?
- What can I expect if I make the change? I.e. what are the potential rewards? (E.g. Financial rewards, operational rewards, etc.)
- What conditions need to be met to give the best chance of success?
- What factors do you need to consider before deciding on a specific optical sorter?
An optical sorter’s sorting capabilities refer to the number of materials that specific equipment can sort through in an hour, e.g. 20 ton per hour.
- The efficiency of the sorting system and the mechanical feeding system
- The quality of the image processing and the image classification system used
If you want to get accurate readings, consider looking for a device that has an adjustable feed rate and high output.
In most sorting situations, it’s hard for products to be classified neatly into “accept” and “reject” categories.
Carryover rate refers to the percentage of a good versus the bad product. It’s as simple as that.
Other Factors to Consider
Before making a purchase, you should also consider talking with experienced vendors and consultants. Allow companies to come into your facility to:
- Make an initial assessment
- Review any data you may have on your material volume
- Review data on any expected material changes and percentage recovery
- Material residue
- After the evaluation, request for a written report that includes:
- Feasibility of using the machine
- Expected tangible improvements
- Any other modifications/changes needed to your operating system to allow the new equipment to perform properly
- Budget cost estimate or estimated operating costs
In addition, you can opt to send a stream sample of your material to potential vendors for testing – by doing this;
Types of Optical Sorters
There are two main types of color sorters namely:
- Chute-type color sorters
- Belt-type color sorters
In this chapter, we shall look at each of these sorters, their primary features, benefits, applications, and drawbacks of each.
3.1 Chute-type Color Sorter
A chute type color sorter is basically a sorter machine that has a chute where the materials are fed into in a vertical manner.
Once the contents are poured inside the device, gravity takes its course, pushing the content down and into the sorting system.
As the materials slide down the chute vertically, they collide with each other, creating friction and larger vertical movement ensuring that no elements are stuck or left behind.
This type is the most common, especially in the food industry, distribution, recycling, and waste management industries.
It’s also ideal for anyone looking to save a few bucks, thanks to its lower prices, especially when compared to a belt-type sorter.
However, a chute-type sorter can’t be used to sort all materials as it has different channels specifically designed based on sizes and shapes of the material.
This machine is designed to screen the broken, defective, and any deformed object from the raw materials and then classify the products accordingly.
An excellent example of an industry that can benefit from a Chute-type sorter is the tea and coffee beans industry.
This is because the machine is able to quickly and efficiently sort through different types of tea leaves or coffee beans and grade them based on their weight, size, color, shape, and much more.
3.1.2 Chute Optical Color Sorter
This type of sorter has higher capacity output because it’s able to sort out materials faster and in larger volumes. It’s best suited for materials with a lower percentage of defects because of the speed and the manner in which it sorts the content out. As earlier mentioned, Chute type sorters are widely used in:
- Food processing
- Waste management
- Plastic industry
Chute optical sorter machines offer a wide range of screening capabilities for a variety of products.
Simply put, the sorting capacity of a Chute-type optical sorter depends on the number of screening units. I.e. some chute color sorters have different structures used for sorting.
Some of them include single layer color sorting and multi-layer color sorting.
If you stumble upon a sorter with these features, it means that machine can be able to detect the defects and the good things all at once.
Generally, the machines can sort through 0.2 – 3.5 tons per hour for every chute depending on the materials it’s sorting with an accuracy rate of anywhere between 97 – 99% accuracy rate.
Finally, the sorters can also predict a carryout rate of anywhere between 10:1 to 15:1 or more (depending on the manufacturer.)
Normal & Reverse Sorting Mode
Most chute-type sorters are equipped with two different sorting modes namely:
- Normal sorting
- Reverse sorting
Normal sorting mode is the most used mode when it comes to sorting out materials that may have small portions of defects and impurities.
Reverse sorting, also known as invert sorting is best used for materials that may have larger portions of impurities and defects.
NOTE: Both of these sorting modes can be used to separate flawed objects from the raw material.
Additionally, both sorting modes (Normal and Reverse) can be used individually from the same machine.
Another thing to look out for is the technology used. Quality sorters are armed with high-tech image correction and full-color screening technology.
Image correction technology, also known as non-linear aberration correction technology is used to correct any errors or distortions in an image automatically – it rectifies any image errors caused by a bad signal or a signal error.
Sorters utilizing or using these technologies have a higher chance of providing a more accurate rate of sorting. The best thing about chute sorters is that they are easy to use and operate.
They have a user-friendly interface that is pretty easy to understand.
However, every machine is packed with a detailed guideline to help you better understand how to operate it, ensuring the operation is simple and straightforward.
3.1.3 Parts of a Chute Color Optical Sorter and How they Work
To better understand how chute color optical sorters work, let’s peel it back piece by piece and look at each piece individually.
1. Material Hopper – The material hopper is the initial place where the raw material is fed into the sorter.
Most material hoppers are made from stainless steel material that’s food grade – meaning the stainless steel has passed through the correct bodies to ensure that it’s safe to touch food directly.
If you have a specific metal in mind that you’d prefer to be used by the manufacturer, you should always voice this out because some manufacturers do offer a customized material hopper option.
After the raw materials are put into the material hopper, gravity pushes the content down and onto our next part of the chute color sorter.
2. Vibratory Feeder – We mentioned the vibratory feeder before but let’s refresh your memory. This is the part of an optical sorter that vibrates and equally distributes the raw materials in uniform.
I.e. it ensures the raw material gets inside the chutes in an even manner without any overlaps. A good vibratory feeder will vibrate at high frequency, enabling the raw materials to drop from it evenly and form a single layer of flow.
3. The Chute – Optical sorters have a different number of chutes depending on the manufacturer and its intended use. A sorter can have anything from 1 feeding chute up to 12 or more chutes.
When the materials leave the vibratory feeder, they are fed into the chutes and divided accordingly.
Most chutes are made from aluminum alloy, which allows the raw product to quickly and smoothly pass through in a gliding manner.
NB: the length of the chute also depends on the manufacturer and the sorter model.
Additionally, since the chute has a smooth channel, the speed at which the raw product moves through also increases, thus having a significant effect of the sorting capacity.
The chutes are housed in a dust cover which is specially designed to ensure that no external factors interfere with the screening process.
* The longer the length the chute, the easier it is for the cameras to take images of the objects easily
4. The Cameras – Inside the chutes are high-speed linear array cameras that take photos of the raw products. The images captured by the camera are then processed for the accept/ reject criteria
5. The LED Light – For the machine to properly function, it needs to be able to take clear imaging of the materials it’s about to sort.
With that said, the camera needs light for proper functionality. Optical sorters have LED lights that provide ample lighting for imaging. The light is installed on the front side of the shooting area.
6. The Ejector – After the images are captured, they are processed, and the digital signal from the CPU is sent up to the ejectors which respond quickly and release the compressed air to push them out of the production line.
The air ejected change depending on the accepted or rejected material movement, resulting in a separation of the good and bad material from the raw material.
7. The Filter and Air Compressors – This is the system that every optical sorter relies on to sort and to remove all the wrong products from the good ones.
The system uses information from the CPU to make a calculated decision. For example; after you have inputted your criteria (accept/ reject), the air compressor and filter work together to wean out the bad from the good product.
To put it in simple terms, the air compressor allows for continuous compressed air.
Next, it works with the filter to remove the bad from the good by pushing out compressed air that pushes the bad down or up (this depends on the upward or downward ejection trajectory we spoke about earlier in the previous chapter.)
The air filters then quickly open up and remove any substantial defects in the compressed air.
This helps to increase the accuracy of the sorting as well as extend the machine’s lifetime.
3.2. Belt-type Color Sorter
A belt-type color sorter works precisely as you would expect; it takes the raw material through a belt on a horizontal manner and transfers it to be screened in the image area.
To better understand this, picture how the belt at the supermarket works; you put your items on the rotating belt, and it slowly takes your products from the moment you put them on and in a horizontal and straight manner;
it transfers the products to the finish line (the clerk) This machine works in the same way.
A belt-type optical sorter uses a straight and horizontal forum to transfer the product into the chutes.
The raw materials are divided into smaller percentages and then moved in a smooth and very stable manner – since the belt is horizontal, the raw products are not bounced around at any time.
The main benefits of using a belt-type sorter vs. a chute-type sorter are:
- Belt-type sorters have a higher selection rate. Because the belt is able to carry the material smoothly and steadily, the raw material is easier to capture through image and sort out accordingly.
- This type of equipment can screen very lightweight things – i.e. tiny grains of different sizes and shapes
- Thanks to the horizontal manner that the raw product is taken through, the machine can safely transport the product without causing any damage.
- Additionally, a belt sorter reduces any chance of breakage thanks to its very minimal chances of collision
- Finally, a chute sorter is specially designed to cater to specific shapes and sizes of products, which limits its range of screening. However, a belt-type sorter can be able to sort products of irregular shapes, sizes, and volume.
3.2.2 Belt Optical Color Sorter
A belt-type optical sorter will still sort your material but in a different manner. The machine, as mentioned above, uses a horizontal drop (as opposed to the vertical drop from the chute-type optical sorter.) This type of optical sorting device is mainly used to sort and grade very light, fragile, and irregular industrial product materials such as:
- Watermelon Seeds
- Sunflower seeds
- Nuts, cashew, almond, raisin, jujube, cotton, and pistachio seeds
- Lyceum Chinese
- Shrimp skin
- Ore and coal
- Salt, sugar
- And many other industrial products
Most belt-type sorting machines offer a sorting capability of anywhere between 1 ton per hour to 2.0 tons per hours – this of course still depends on the materials being sorted.
Additionally, a belt-type sorter can offer a sorting precision rate of 98 – 99.9% accuracy and a carryout rate of anywhere between 10:1 to 15:1 (good: bad) depending on the manufacturer.
Normal & Reverse Sorting Mode
Similar to the chute-type machine, the belt-type device uses two sorting modes namely the:
- Normal sorting mode
- The reverse sorting method
The normal sorting mode is still the best mode to use when you want to sort out raw materials that contain large amounts of impurities.
For example; the normal setting mode can be used to separate the good nuts from the raw product. The reverse sorting mode is better suited for the raw products that may contain a number of impurities or contaminations.
Still using the example of the nuts; the reverse method can be used to pick or wad out the bad or defected nuts from the raw products.
*Some belt-type sorting machines can handle both normal and reverse sorting modes at once.
3.2.3 Parts of a Belt Color Optical Sorter and How they Work
A belt type optical sorter is pretty straight-forward. It uses very simple and easy technology and how it works is just as straightforward.
It’s very similar to a chute-type sorting machine but with a few tweaks here and there. Here are the main features of a belt type optical sorter:
- The Belt – After the material hopper, this is where the raw materials are thrown in and distributed in an even manner. The belt moves the raw materials from the primary input area and in for an image shot.
- The CCD Camera – Similar to the chute-type model, the cameras here collect a high range of images for the CPU. The photos are mainly in color detection mode (i.e. red, green, brown, etc.)
- The Sensors – Most belt-type sorters use DSP plus FDGA sensors and linear screening technology to help further differentiate the different colors. To put it in simpler terms, the sensors found here are able to distinguish between; let’s say a light brown and a dark brown/bright green; dark green, etc.
- The Ejector – This works just the same as that found on a chute-type optical sorter. Its primary purpose is to detect any rejected items and remove them accordingly to help with the accuracy of the final product.
Before we talk about how a belt optical sorter machine works, we should cover the different types of structures you might stumble upon. There are two types of structures that are very famous namely the:
- Single layer structure
- The two layers of structure
The single layer structure uses high-resolution CCD digital cameras to find any defective particles in the raw product.
Additionally, this type of machine has high-speed mini ejectors that help improve the sorting capabilities The two layers of structure use double sorting programs, which are performed at the same time.
This means that the first process filters the material into place while the second process selects and classifies the content accordingly.
The best part of using this type of sorter is how easy it is for you to control the settings including the:
- Start program
- Color process selection
- Close, and much more
How it Works
Now that we’ve discussed the parts found in a belt-type optical sorter let’s talk about how it works and how it’s actually different from a chute-type optical sorter.
After the raw product is put into the material hopper, it’s then passed down onto the belt for further assessment. Here, the raw products are dropped onto the belt and evenly transported to the CCD cameras.
Before that though, you should note that because the materials are on the belt, you’ll be able to view all sides of it (what we mean is; because the belt is flat, you will be able to see how they are evenly distributed and much more.)
A belt type sorter takes into account the different color selection of all the raw material that passes through (still depending on your set criteria.)
In addition, it also detects the colors of any material that passes through that resembles any previous raw material.
*What we mean is; if there were grain or content that had passed through with a near-similar color to the set “accept” criteria but didn’t pass the test, the machine would be able to detect this and discard any other raw materials that pass through with the same similarities and vice versa.)
When the raw product reaches the end of the belt, it’s then imaged using the high-speed CCD cameras.
At the same time, this is happening, the sensors receive the images within milliseconds, process and analyze the images, and finally send out a signal of “accept” or “reject”.
Once the CPU (Central processing unit) receives this signal sent from the sensors, it controls the ejectors to open or close accordingly (close if the material passes the set criteria or open and blow out the “defect” or “bad” material out from the processing line.
At this point, we’ve covered what an optical sorter is, the benefits of using it, how it works, and the different types of optical sorters available in the current market.
It’s now time to find out all the ways you can apply these machines in your company for better yield, lower labor costs, and much more.
Let’s find out which industries can benefit from buying and using high-quality sorters.
Application of the Optical Sorters
Now that we know the purpose and types of optical sorters in the market, we agree that they are essential in boosting productivity.
You will be saving time and energy when you need to sort out just about anything.
Also, you will be boosting the aspect of perfection in your end product – something that you are less likely to meet under normal circumstances.
Optical sorters will come in handy in several industries.
The following are some of the best applications of the optical sorters, which show their importance and relevance.
4.1 Application Industrials
Many industries are embracing this type of technology to help sort out items with the aim of only producing the best quality. Below is how optical sorters play an essential role in different industries.
• Food Industry
The food industry is a sensitive department, and it is best that you uphold all the food safety processes and security measures.
You want your product to be of nothing but high quality.
With that said, how you process the food from the initial stage matters a lot. From how the food is grown to how it’s processed and packaged, every stage needs to be efficient and effective.
Your food needs to be sorted and categorized in a manner that the bad pieces are removed from the final product.
Optical sorting equipment will help you get rid of unwanted vegetable matter, sticks, any stones, as well as stems.
An optical sorter machine will also enable you to eliminate dangerous or harmful content from the food substance;
thus eradicating any cases of food poisoning in your business.
Food safety goes hand in hand with the quality of food you produce.
Your machine will be ensuring that the foods remain up to standard in accordance with the regulations.
The choice to involve optical sorters comes with the advantage that you will offer high-quality foods while at the same time retaining aspects of cleanliness and health.
This type of machinery will address issues such as cleaning, removal of defected foods and foreign material, and quality end products.
The best part of buying an optical sorter is that if you want to package the food, you can also employ the use of optical sorters.
Aside from removing the “bad’ items from the “good”, the machine can also be used to aid with the packaging process.
What we mean is, you can use sorters to group the products for packaging.
For example; if you want to package a darker grain separate from the lighter one, all you have to do is the program the device and you’ll end up with two piles of dark and light;
making it easier for you to package the end-product accordingly.
• Chemical Industry
In the chemical industry, the substances you will be coming across are probably hazardous.
This makes it unsafe especially if you do not have the right protective gear.
In an effort to help minimize on risk; not just to the individual handling the chemicals but also to the individuals who will use the chemicals later, sorting is essential.
You must also ensure that you have consistent operations.
This will, in turn, optimize your productivity while at the same time lowering the cost of services. How is this possible you may ask?
Optical sorters can identify differences in color, size, as well as consistency.
Unlike the use of human resources to test chemicals, it is, and it will increase the risk of contamination from exposure.
When you are working with chemicals, you need to understand that purity is critical. Mixing the wrong chemicals can be very harmful.
Chemicals are very broad in nature; meaning that they are different in several ways.
Rather than having to test every single drop with the aim of determining which the best is, why not invest in an optical sorter with the right features.
You will be able to distinguish between chemicals faster and easier without exposing yourself and your employers to any dangers.
• Plastic Industry
Plastics come in different qualities to suit varying uses. More importantly, plastic continues to transform, and you will notice that the industry is customizing the use of plastics to day-to-day applications.
Plastics are used by tons of other industries including the packaging, medical, electronic, as well as transportation sectors.
If you are in the plastic business, your quality needs to cater to the relevant sector it’s going to be used for.
This means that you must be careful of the type and quality of plastic you produce.
For example, the quality of plastic for medical purposes will vary when compared to plastic made for the transportation industry.
A sorter will enable you to have the ability to sort through tons of plastics per hour without compromising on quality.
In addition, you will be able to run tests before releasing any plastic products into the market.
We all agree that if you are going to release plastic products in large masses, then you will need to ensure that they are the same.
This is in terms of color, size, as well as the density of the plastic. Imagine producing millions of plastic jugs only to find out that half the number is different from each other, which means that they are defaults.
You will not only be running losses, but you will also be destroying your brand in the long-term.
Opting to buy an optical sorter device will ensure that this never happens.
• Pharmaceutical Industry
We rely on pharmaceutical companies to produce the right medication to help prevent and/or cure a given ailment because a slight mistake can cause long-term effects on you and your loved ones.
To avoid such occurrences, optical sorters can be used to distinguish between medications; especially tablets and for production purposes.
When visiting a chemist, you will notice that some drugs look very similar.
Without the right labeling, one may easily confuse them.
An optical sorter provides you with the ability to clearly distinguish between different drugs and testing equipment as it has the ability to differentiate between small differences in shape, size, color, as well as composition for each medicine.
The use of optical sorters also means that you can increase the production of medication and other pharmaceutical products. You can also produce enough to reach out to all targeted individuals.
You must have heard of hospitals running out medicine or equipment only for them to be told that they must wait. Such cases leave patients exposed.
The faster you can sort high-quality products in this industry, the quicker you will also distribute them.
Use optical sorter technology to separate different types of drugs and equipment while at the same time ensuring that they all meet the desired standard as provided by the law.
• Wood Industry
Wood is a broad name that can also refer to wooden products such as tables, chairs, decorative items, as well as outdoor purposes such as fencing.
You probably use wood for several reasons in your everyday life. Some factors you consider when looking for a certain wood include:
- The wood
- The size
- Defects on the wood
- The treatment process; if any
- And the intended use
Additionally, you also need to consider waste management – how can I dispose of the wood afterward?
Optical sorters will ensure that you have the best quality wood as it’s able to sort out wood materials.
This shape and color sorter machine is able to classify and categorize different types of woods based on texture, dents, size, shape, etc.
This means that a manufacturer is able to easily sort through heaps of wood in a small amount of time.
The packaging industry aims to provide safety and security measures of all your products.
You want to be able to pack your items and ensure that they arrive in good condition.
To help you to meet this objective, you must use the right packaging material.
Packaging materials differ in several aspects.
Looking at the market, you will identify the differences in the type of materials used for packaging, the shape, size, design, as well as the purpose.
While the shape, size, and material are all about your preference, you must be precise about it. The material you pick is dependent on its purpose.
Using an optical sorter will help you to sort the packaging materials and products in the right category.
They will ensure that products of the same design and color are packaged together.
Your consumers do not want to feel cheated of their purchase.
With that said, you want to ensure that any products with a default such as color or size difference are packaged accordingly.
The consistency in quality of the products will boost consumer loyalty and in turn increase sales. This type of technology is accurate and reliable.
This makes it ideal for this industry in terms of higher production, consistency, and unmatchable quality.
• Agriculture Industry
In the agricultural industry, people are looking to have the best produce. For you to meet this objective, you must plant the best quality seeds.
Optical sorters will sort different types of seeds to ensure your end products are uniform. Despite the difference in seeds, you can sort seeds ranging from corn seeds, carrots, onions, soya, as well as grass seeds.
Why is this important in agriculture? It increases the chances of maximizing germination as well as bettering the appearance of the seed product.
If you want to produce similar products, optical sorters will ensure that the seeds are similar in size, shape, and color.
In addition, you will be able to remove seeds that have any defects before planting.
You can get rid of seeds with errors such as diseases, seeds with insect damages, broken ones, as well as those you do not want to be associated with that specific batch.
Some seeds are similar in every way, but they differ in terms of color. As a farmer, you are sometimes looking to have a perfect collection of seeds that are similar in every way;
as well as healthy and clean. You can use optical sorting for this purpose.
You will be able to reduce the possibility of cross-contamination of seeds, which means that you will improve your overall levels of germination.

Every farmer wants to have the best, and you can stand by this objective with the help of an optical sorter.
You have the ability to increase productivity while at the same time; lower operational costs.
• Recycling and Waste Management Industry
This industry comes across several items and products that cannot be recycled without sorting them out.
For example, if you recycle single commodities such as plastics or metal scraps, you must first ensure that the materials are not together.
The use of a human resource such as in third world countries is not accurate, thus the need for optical sorters.
Optical sorters make the process easy and fast, allowing companies in this industry to increase productivity.
You will be able to minimize mistakes when you are recycling – for example, an optical sorter can remove small pieces of plastic that have been mistakenly put in the glass pile.
The objective of including this machinery in different industrials is to promote efficiency and reliability.
These machines can boost performance and production while remaining strict to quality assurance.
Every industry wants to sort their products depending on different aspects such as size, color, quality, variation in material, and remove defaults.
This means that you will produce more and minimize mistakes.
A high-quality product reduces the risk of any negative discrepancies meaning you will be able to satisfy your market demands.
4.2 A Complete Materials Sorting List
Optical sorters are beneficial for use in the above industries. To help you to narrow down on the possible use of the machinery on a day-to-day basis, let us have a look at the materials you can screen with the help of an optical sorter.
The optical sorter can sort different types of leaves such as tea, Cifar filler, free lamina, as well as dehydrated vegetables. It will remove unwanted items like stems and impurities. Leaves such as tea leaves vary in quality, and we know that they are of different breeds and grades. The right machine will help you sort these categories fast and conveniently.
An optical sorter will be able to leave you with just one type of bean while at the same time ensuring that the selected beans are pure and of the best quality.
Obtain your mung bean, peas, soybean, pigeon peas, as well as chickpeas and common beans from the collection with ease.
Sort out your gummy candy in terms of color, shape, and size fast. Also, you have the ability to eliminate any candy that has unpleasant defaults.
Many types of spices are ground, and it can be difficult to separate anything from them.
With the help of sorter technology, you can ensure you have a pure product.
Some of the spices it can sort include nutmeg, chili, cinnamon, clove, cayenne pepper, and mace.
Sort out spices before the production stage to ensure you get rid of unwanted products before arriving at the final stage.
