Double Deck Dry Destoner SOK

Double Deck Dry Destoner SOK is a modern grain cleaning machine. The features include high performance, small overall dimensions and low power and air consumption.

Due to two sieve decks, the machine is able to separate grain into two fractions: heavy and light, with simultaneous separation of higher density material such as Stones, pieces of metal and glass from corn or other grain products.
The Double Deck Destoner is used mainly in grain cleaning in the wheat milling process. On the top sieve deck, with air stream suitably regulated, very light fractions (chaff, dust etc) can be removed by aspiration (2-3%) that cannot be used for milling or sort the grain into light and heavy fractions (in proportions 30-70%) using separate light fraction cleaning line on engineering diagram.
