METHOD FOR FERMENTATION IN FERMENTED SOYBEANS AND CIRCULATION VENTILATION TYPE FERMENTATION CHAMBER IN FERMENTED SOYBEANS

摘要

PROBLEM TO BE SOLVED: To provide both a method for fermented soybeans production, with which high-quality and uniform fermented soybeans can be produced by more uniformizing a temperature of fermented soybeans stored in a container and a fermentation progress and a circulation ventilation type fermentation chamber in fermented soybeans suitable for fermenting soybeans. SOLUTION: In this circulation ventilation type fermentation chamber, the average air velocity of circulation ventilation is 0.5 m/s to 1 m/s and an average temperature difference between an inlet part and an outlet part of a container housing chamber is <=3 deg.C to ferment soybeans. The circulation ventilation type fermentation chamber suitable therefor is provided with two independent container housing chambers and two independent air-conditioned air circulation ventilation systems.
