METHOD FOR PURIFYING OF DUST-AND-AIR MIXTURE DURING PROCESSING OF GRAIN PRODUCTS AND APPARATUS FOR EFFECTUATING THE SAME Russian patent published in 2005 - IPC

FIELD: agriculture, in particular, processing of cereal products.

SUBSTANCE: method involves inertial settlement of heavy particles followed by process of inertial settlement of light particles; before settlement of light particles, spraying water in dust-and-air flow and introducing finely-dispersed bone flour particles, said bone flour adhering onto moistened outer surface of light particles to thereby increase weight of said particles and separate the latter from said flow for further utilization in feed production. Apparatus has two inertial dust catchers arranged in succession. Bins with closures are located in lower part of each of said dust catchers. Ejector with water spraying head and bone flour spraying bin with closure are located in air duct, in front of second dust catcher.

EFFECT: increased efficiency in purifying of dust-and-air flow and provision for obtaining of crude material for producing of combined feeds.
