In recent years, China's color sorter has developed more rapidly, and it has been widely used in processing industries that require color sorting of solid particulate materials, such as food, agricultural products, chemical appliances, and product processing industries. In occasions where unqualified products and qualified products cannot be separated by sorting equipment because of their close particle size, or where the density is basically the same and cannot be separated by specific gravity separation equipment, the color sorter can effectively separate, and its unique role is very obvious.

So how do we judge the quality of the color sorter and the basis for purchasing the color sorter!

1: Processing capacity

The processing capacity is the number of materials that can be processed per hour, and the unit is 1/h. In addition to the different configuration and structure of the color sorter recognition system described above, the factors that affect the size of the processing capacity are also an important factor. The size of the general color sorter is determined by the number of channels configured. The specifications generally range from 32, 48, 80, 96 and 128 channels. At the same time, the processing capacity is closely related to the variety of raw materials, the proportion of impurities contained, and the required selection accuracy. (Rice color sorter)

2: Selection rate

Selection rate refers to the percentage of the number of impurities selected from the raw grain to the total impurities contained, also called color selection accuracy. The factors that affect the selection rate are mainly determined by the flow rate and the model of the color sorter, that is, the performance. Generally speaking, the CCD method is higher than the silicon photocell method, and the multiple selection structure is better than the single selection structure. The selection rate of multiple color sorters equipped with CCD sensor technology can reach more than 99%, while ordinary color sorters equipped with traditional sensors for one-time color sorting are difficult to achieve the calibrated index in actual production. In addition, the level of selection rate It is also affected by the ratio of high to low. (Miscellaneous Grain Color Sorter)

3: Take-out ratio

Take-out ratio refers to the ratio of the amount of impurities in the waste material selected by the color sorter to the normal rice or wheat grains. The take-out ratio can be set, generally around 1.3~1.5. If the take-out ratio is set too high, it will affect the two indicators of selection rate and processing capacity; if it is set too low, the selected waste Too many normal rice grains or wheat grains contained in it will cause waste. If it is processed again, a certain amount of manpower and material resources will be invested, which will cause a lot of trouble and economic loss.
