Peanut chocolate sorting

PROBLEM 

Processing chocolate or peanuts requires waste product or dust resulting from processing to be removed. Remove for example chocolate particles for the chunks, will prevent the conveyors roller and other parts of the machinery from being coated in chocolate, requiring machine stoppages and loss of productivity. 

SOLUTION

Applying an electrostatic charge to the product as it feeds past a grounded roller, causes the small lighter particles to stick to the roller, while the larger heavier particles pass though the electrical field to a conveyor below. As the grounded roller rotates the waste material is removed by a doctor blade or brush and neutralised before being collected for recycling or reprocessing.
