Application

Double Deck Dry Destoner 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.

Construction

Basic assemblies of the Double Deck Dry Destoner include: • body with installed sifting frames (frames dimensions for SOK-15K: width =1245 mm, length =1100 mm; for SOK-20K: width =1445 mm, length =1300 mm); frames are protected with bars allowing easy inserting and taking out of sifting frames; body elements also include: - product outlet: - light fraction “b”, - heavy fraction “c”, - stone outlet “e”, • cover with sight glasses to observe sieve operation, • product inlet with flap valve regulated by return spring, • supporting frame with shock absorbers, • drive assembly inducing vibratory movement of the device, • supporting structure with installed: - product inlet pipe “a”, - air outlet “d” with regulated flap by means of regulating assembly, - manometer, • outlet channel, • stone container.

Operation

Product intended for cleaning is gravitationally fed through the inlet to the top sieve. The product, through directing elements located in the cover, is uniformly distributed on the whole sieve’s width. Due to vibratory movement and impact of even air stream passing from down to the top through both sieves and forming air cushions over top and bottom sieve, the product is spread on the whole sieve surface. Air cushion created over the top sieve lifts the light fraction to the outlet “b”, heavy fraction and stones get through top sieve perforated sheet metal wholes to the bottom sieve lapped with wire mesh. On the bottom sieve, air cushion lifting the product, that is transported to the outlet “c”, allows stones that contact the sieve due to vibratory movement, to move upwards to the outlet “e”. In order to achieve optimum selection rate, inclination angle and air quantity can be adjusted, as needed.
