As the name suggests, color sorting is simply to sort the things according to their color. It can be easily done by seeing it but when there are too many things to be sorted and it is a repetitive task then automatic color sorting machines are very useful.  These machines have color sensor to sense the color of any objects and after detecting the color servo motor grab the thing and put it into respective box. They can be used in different application areas where color identification, color distinction and color sorting is important. Some of the application areas include Agriculture Industry (Grain Sorting on the basis of color), Food Industry, Diamond and Mining Industry, Recycling etc. The applications are not limited to this and can be further applied to different industries.

Industrial

Lets's take a look to some industrial color sorter machines.

Sorters can be divided into chute-type and belt-type color sorters.

Belt-type color sorters break a smaller percentage of the material (important for nuts), and the product stays relatively static during the transport process as it moves horizontally on the belt. In the chute type, material slides on the chute because of gravity, causing collision, friction, and larger vertical movements, thus worsening the ratio of broken material. The belt structure makes the transmission smooth and stable without bouncing of material.

Chute-type color sorters are more common especially for food, as prices are lower, capacities are higher, and products can be seen more easily from both sides, which is important when a dehulled grain has hull only on one side. Chute sorters are usually applicable to specific products, as the chute is designed with special channels for this kind of material based on sizes and shapes of the material. For example, 5 mm chutes are used for rice, grain and plastic granules. Flat chutes are right for plastic flakes, such as PET, or milk bottle flakes.
