FIELD: agricultural engineering, in particular, production of fertilizer by processing of manure, bird dung, and other organic wastes.
SUBSTANCE: apparatus has fermenter made in the form of closed vessel with floor. Pipelines positioned in lower part of floor are provided with air supply openings connected with fan. Pipelines are arranged in parallel channels disposed in central portion of fermenter floor and at wall and floor junction sites. Central channel is closed with metal plate so as to define slots between metal plate and fermenter floor. Channels arranged at wall and floor junction sites are closed with protective grids.
EFFECT: enhanced reliability in operation, reduced costs of construction and mounting works, and effective utilization of air oxygen during aerobic fermentation process.
