METHOD TO OBTAIN BIOHUMUS AT ISOLATING A BIOMASS AND EQUIPMENT FOR FODDER SUBSTRATE PROCESSING AT ISOLATING A BIOMASS Russian patent published in 2002 - IPC

FIELD: utilization of organic wastes. SUBSTANCE: the wastes of organic origin are mixed at certain ratios with a filler to be treated in special biofermentative chambers under aerobic conditions. The product obtained - a fodder substrate - undergoes subsequent treatment in special modules - vermicultivators by using industrial population of earthworm of Eiseniafoetida species. When vermicultivation process is over isolated earthworms return into technological cycle for reproduction in the next working module. The earthworms isolated from biohumus in a breeding module totally pass to be processed for fodder protein to be further used in fodder production. Complete cycle of substrate-biohumus processing at isolating a biomass lasts for 50 d. Substrate is loaded into 2 bunkers (1) facing each other and divided by a biomass receiver (2). Bunkers' bottoms are designed to be inclined at angle of 10-35 deg. towards a biomass receiver (2). Lateral walls of bunkers (1) have got holes (3) for aeration and installation of heaters. EFFECT: higher quality of biohumus obtained. 3 cl, 1 dwg _
