Coffee Color Sorter

Colour sorters are used for the food processing industry, such as coffee, nuts, and oil crops. The goal is the separation of items that are discoloured, toxic (such as ergot), not as ripe as required, or still with hull after dehulling such as sunflower seeds..Colour sorting machines are most commonly used in the sorting of agricultural grain and rice, as well as in the processing of food products, such as coffee, nuts and oil crops. The optical sorter separates any stones, mouse droppings and discoloured, toxic or otherwise unacceptable items.For the food sector, colour sorting serves the purpose of risk management, ease of product handling and inspection, reducing drudgery and faster food processing. Industries employ different methods to analyze the colour of food products. The two most commonly used techniques involve colourimetry and spectrophotometry.
