Air basin protection in the bulk manufacturing of fodder protein

Biomass of microorganisms in aerogenic dissemination is an allergen and causes bronchopulmonary pathology. Organized source of air-gas emissions (AGE) in the production of protein - vitamin additives of any kind of raw materials are driers, bioreactors and separators. There were provided the results of a survey of a number of AGE production. There were developed new types of gas treatment equipment - vortex absorber and a mesh mist separator with continuous regeneration for bioreactors and separators. The greatest contribution to the AGE of fodder protein production make drying compartments. New technical solutions for their technological improvement did not on the path of increasing of gas treatment equipment capacity, but on the path to change hardware technological scheme. There were developed and tested a few schemes with varying degrees of closure of drying agent's (DA) circulation. The final decision was the scheme with a fully closed-loop circulation of DA, thus ensuring the full environmental safety and explosion-proof of drying compartments.
