METHOD OF STERILIZATION OF MICROBIOLOGICAL PRODUCTION APPARATUS Russian patent published in 2001 - IPC

FIELD: microbiological industry; yeast- growing apparatus. SUBSTANCE: sterilization method includes washing of inner surfaces of apparatus with water and disinfection solution followed by steaming which consists in replacing the air by water steam which is then discharge to atmosphere through exhaust pipe.
