Sortex Chute Color Sorter has two main functions of sorting and grading.

The sorting function is designed to diagnose the defective, broken and deformed objects from the raw materials and then get the classified products.

The Grading Function is required for fine screening. For example, Tea and Coffee beans.

People who prefer the tea have big requests for top-level tea leaves and this function could quickly grade the tea on the basis of color, weight, size, shape etc.  


Sortex Chute Color Sorter has a wide range of screening capabilities for different products.

It is generally about 0.2~3t/h sorting capability for every chute according to different materials.

Its color sorting accuracy is not less than 99% and the carryover rate(bad: good) around 10:1.

Sortex provides various voltage ranges of color sorters to match different markets’ requests.

For American Markets, the rated voltage is 240Vac and in Europe is 220Vac. Besides, Sortex Chute color sorter can be configured of use at the rated voltage of 380V and 415V.  

Sortex Chute Color Sorter has two different sorting modes: Normal Sorting and Invert Sorting.

Both Normal sorting mode and the reverse mode are used to separate quality objects from the raw mixture.

But there is a little difference between these two modes.

Normal sorting mode is suitable for materials with a small proportion of impurities and defects.

However, the reverse sorting mode is better for the materials with a large proportion of impurities and defects.

 And both sorting modes can individually be used at the same Optical Sorter.  

Sortex Chute Color Sorter has different structure includes single layer color sorter and multi-layer Color Sorter.

Each layer is an independent sorting unit. Each sorting unit could select a sorting mode separately.

Therefore, Single layer Optical Sorter could recognize the faulty things and the fine things at one time.

Multi-layer color sorter could separate the raw mixture. Meanwhile, it could divide the products into different grades.

Generally, the sorting capacity also depends on the number of screening units.  


Sortex Chute Color Sorter has both unique image correction technology and full-color screening technology.

This unique image correction technology, also called non-linear aberration correction technology, can automatically correct the non-linear images because of distortion and aberration caused by signal errors during image collecting.

Sortex Chute Color sorter usually sorts the raw material according to RGB color difference.

Sortex Chute Color Sorter add another camera to collect image saturation information.

Both these unique technologies can raise up the accuracy of sorting.

Sortex chute color sorter is an automatic tool with a CCD camera and integrating light.

It uses the high tech photoelectric diagnostic system to classify the heterogenic particles.

Sortex chute color sorter help to raise production and improve the business grades.  

Sortex Chute Color Sorter is easy to operate. It has a built-in humanized operation panel. Sortex designs an easy understanding icon for each function. Meanwhile, all processes have been optimized to ensure the operation is simpler and more logical.

In terms of hardware, inner CPU adopts original American chips. After first setting, you can easily use one-button start function for the same raw materials.

 A network control module is available as well and it supports TP/TCP protocol. Let Chute Color Sorter connect to the internet and you can easily control the machine through your smart devices such as ipad, iPhone, and Android phones.  

How does it work?

Color Sorter Working Principle

Graphic: Color Sorter Working Principle

Sortex Chute Color Sorter is a complete sorting system and every component need to work together to finish sorting task.

  1. The Raw Material Mixture drops down from the Material Hopper first and passes through vibratory feeder enter the chutes.
  2. The vibratory feeder can make sure the objects fly to the chute in a line at the same speed.
  3. They are imaged by the CCD high revolution Cameras, the sensor mounted on the back of the cameras will analysis images and send a message of acceptance or rejection to chip processor.
  4. Finally, ejectors would release the compressed air and change defective grain’s motion track to separate them from the fine grain after receiving rejection signals from the chip.



In order to complete this sorting process, all the components need to work together.

1.Material Hopper

Sortex Chute Color Sorter’s material hopper is made of #304 stainless Steel that is food grade materials.

#304 stainless steel can touch the food directly according to CE and CAS standards.

We also help customize material hopper with another metal if any requests.

2.Vibratory Feeder

Vibratory Feeder on the Chute Color Sorter is usually used to ensure the sorted objects evenly arrive the chutes without any overlap.

Our vibratory feeder has a big characteristic that vibration is even and frequency is stable, which could make sure all raw material drops from feeder evenly and form a single layer of waterfall flow.

The chute is made of aluminum alloy and it conveys the screened objects to the shooting area.

 Plenty of objects leave from the vibratory feeder and are divided into 64 different movement routes along the chutes.

Because the length of the chute is fixed, the cameras can easily catch the objects and take photos.

During this process, it is necessary to select a smooth and durable channel.

Smooth Channel would raise up the speed of the grain and High Speed will affect the sorting capacity.

A dust cover is designed on the chute, which will greatly reduce the influence of external impurities on the screening process.

 What’s more, some customers would love to mount a heater at the back of the chute. The heater is a benefit for objects drying.

4.CCD Camera with High Revolution Sensor


Graphic: Color Sorter’s Sensor

High-Speed CCD Linear array Cameras take photos for the accelerated objects and the recognition accuracy up to 0.06mm.

Be able to provide HD image as high as 200 million pixels per second.

High Revolution sensor could quickly and exactly recognize the 0.01mm2 defects.

5.LED Light

LED light provides a very good fill light for imaged products and it is installed in front of the shooting area.

In order to improve the images’ sharpness, sortex adds in a row of cold LED light, High luminance, low power consumption, 5k hours long life, which is a benefit for identification.

After receiving the digit signals from CPU, the ejectors that are 1 Billion times.

High-Frequency Solenoid Valve responds quickly and release the compressed air.

The air would change the rejected or accepted products’ movement routes, which separates the bad or good grain from the raw materials.

Sortex selects a powerful and precise nozzle with 4.75MM port size.

7.Air Compressor and Filter

Air compressor allows to continuously provide compressed air. It is always required to work together with an air filter.

And the air filter quickly filters out solid impurities in the compressed air, which helps extend the lifetime of the machines.

Besides, it increases the accuracy of the sorting.  

How to install and debug?

Sortex Chute Color Sorter will provide you the installation diagram and operation instruction with packaging.

Every Color Sorting Machine requires a separate metal support platform and material lifting system.

The Metal Support Platform will lift the machine in a specific height, which will facilitate the collection of the material at the outlet.

The lifting system is used to deliver the material to the hopper.   Sortex Chute Color Sorters are approved by CE and CSA.

It is a safe and stable color sorting machine. Sortex has a 20-year manufacturing experience of the color sorter, and we can manufacture 500 pieces of Chute Color Sorter each month.

Regularly, we can arrange the delivery in 10 days.   Every Sortex Chute Color Sorter is required to do 100% performance testing before packing, which ensures all functions are good.

Meanwhile, we would organize a professional engineer team to provide free on-site installation, operation training, maintenance and 24 hours online troubleshooting.
