SG Optical Sorting Equipment

SG Optical Sorting Equipment is a 4 chutes machine that sorts and classifies materials based on their optical properties. It can automatically recognize the size, color, shape, and defect, and then decide to which should be remained and which should be eliminated. This kind of color sorting machine is widely used to small size materials such as rice, grains, tea, plastic, and another non-destructible product. SG Optical Sorting Equipment has two regular sorting modes, they are normal sorting mode and reverse sorting mode. Both modes are used to separate the good materials from the raw mixture. Normal sorting mode is better for a mixture containing a lower proportion of impurities. SG Optical Sorting Equipment requires an extra air compressor, air storage tank, Hoist, installation platform. The Hoist can carry the materials to the hopper and the installation platform give the sorting machine a specific height, which is a benefit for material collection. SG will provide free installation service for any customers, no matter a private workshop, or large processing factory.

Optical Sorting Equipment

SG Optical Sorting Equipment, also called optical sorter, is a vertical color sorter machine with four chutes. It sorts and classifies grains and some industrial products based on their optical properties.

In Agriculture, most farm and food processing factory use the optical sorting machine to separate the fine grains from the original mix. For example, it is widely used to sort rice, wheat, tea, coffee, and other corps.

The optical sorter is also allowed to separate plastic from many color mix. It can automatically recognize the size, color, and shape information according to initial parameter settings.

SG optical sorting technology improves crop quality through the sorting process, which gives farmers and food processors a higher sales profit. It can also save a lot of human sorting costs.


SG Optical Sorting machine has four times sorting ability than a mini color sorter. It may separate two to twelve tons of grains per hour due to different types of sorting objects.

The Sorting accuracy is close to 99%; that means the machine can pick out almost good grains in one sorting process. The carryover rate(good: bad) at the first sorting exceeds 10:1; the percentage in the second time will reach 80:1.

Sorting Mode

SG Optical Sorting Equipment has two regular sorting modes: Normal Mode and Reverse Mode. Both sorting methods are suitable for grains sorting. Normal Mode is better for a mixture containing a lower proportion of impurities. But Reverse Mode is ideal for mixtures with a higher percentage of impurities.

Optical Sorter is suitable for a wide range of agriculture products. You may check more details in below tablet.


There is a single-layer structure design. SG optical sorter has four chutes in a row, and each chute connects to an individual sorting unit.

Every sorting group can work independently; This modular design reduces the risk of the machine completely failing at the same time. In other words, it increases the stability of the mechanical performance.

A 10” color panel makes the operation more efficiently. All parameter settings are integrated into the visual operating platform. After finishing the first set, the data will be remembered, and just one key can start up the machine.

Besides, Network Link technology makes it possible to control the machine remotely. Through cloud technology, color sorter can update software programs on time.


SG Optical Sorting Equipment is a complete optical sorting system which consists of several major components. Many individual systems must work together to complete the sorting process.

Feeding system
Feeding System is designed to give all material an average speed, and it ensures every object can fly into the image acquisition area.

Identification System
As a core part of the color sorter, the identification system needs to record the optical information of all materials. The non-compliant objects are then found by aligning this optical information and set parameters.

Rejection System
The sorting system consists of auxiliary fittings, finished tanks, jet valves, air compressors, and filters. Pneumatic nozzles come standard with nearly 200 nozzles, caliber only 2-3mm, high resolution, long life, and precise injection.
