Four Indexes for Cereal Color Sorter Evaluation

How to evaluate whether a cereal color sorter meets the standards? This is a major concern for cereal color sorter buyers. In the following, Anysort will give a brief analysis on the four indexes for cereal color sorter evaluation.

Indexes for color sorter evaluation are:

1. Processing capacity

It refers to the quantity of materials a color sorter can process per hour, and is expressed in t/h. In addition to the consistency with production requirements, 10%-15% redundancy shall be considered in the selection of sorter type, to guarantee the normal color sorting effects. The processing capacity is not only influenced by the configuration, structure and specification of the color sorter's recognition system, but also closely related to the variety of raw materials, percentage of impurities and required precision.

2. Color sorting precision

It refers to the percentage of the quantity of black impurities sorted by a color sorter in the total content of black impurities in cereals.

3. Sorting rate

It refers to the proportion of the sorted impurities’ quantity to the total quantity of impurities during one time of color sorting.

4. Carryover ratio

It refers to the proportion of the sorted impurities’ quantity to the normal cereals’ quantity in the rejects. It is also an important index and generally set as 1%-3%. To evaluate the processing effects of a color sorter, the color sorting precision and carryover ratio shall be compared by sorting raw materials with the same content of discolored kernels and at the same flow, on the premise of excellent and stable performance.
