The primary function of a coffee bean color sorter is to ensure the quality and consistency of coffee beans, which is crucial for the final taste and flavor of the coffee. Here are the key functions of a color sorter:

1. Removing immature green coffee cherries: Mature coffee beans are key to producing high-quality coffee. Immature beans may carry an unpleasant sour or astringent taste, and color sorters can remove these by identifying the color and maturity of the beans.

2. Removing defective beans: Defective beans, such as black beans, moldy beans, insect-damaged beans, etc., can affect the overall quality of the coffee. Color sorters can identify these defective beans and separate them from the good quality beans, ensuring the final product's quality.

3. Grading roasted coffee beans: Color sorters can grade coffee beans based on their color, distinguishing between dark and light beans. This grading helps roasters select the appropriate beans for different roasting needs to achieve the desired flavor and mouthfeel.

4. Removing foreign objects after roasting: During the roasting process, foreign objects such as broken beans and stones may be produced. Color sorters can effectively identify and remove these foreign objects, ensuring the purity of the coffee beans.
