PROTEIN FODDER AND BIOHUMUS Russian patent published in 1995 - IPC

FIELD: agricultural engineering. SUBSTANCE: method involves growing larvae in substrate based on swine manure, blowing them with air at 30-70 C and a flow velocity of 0.5- 2 m/s, separating larvae from mixture in at least two steps wherein the thickness of the mixture layer in each following step is 20-30% smaller than it is in the preceding layer. The installation for the realization of the method comprises a cooling system installed between tiers and intended to cool the trays. Tray bottoms are perforated and the trays proper are installed on the conveyor with a provision for changing the inclination angle to its surface. In the device fore removal of larvae from the resulting mixture the power-operated net conveyor consists of at least two sections, each vertically displaced from another and capable of moving at various drum speeds. EFFECT: higher functional and operating characteristics. 5 cl, 4 dwg
