PROBLEM TO BE SOLVED: To provide a method for air cutoff fermentation and an apparatus thereof so that rice bran mostly conventionally regarded as a waste can be utilized for a special fertilizer, a mixed feed and a fermented food for maintaining the health of human bodies. SOLUTION: This method for air cutoff fermentation of the rice bran and the apparatus are characterized by spraying a microorganism such as a cultured lactic acid bacterium or a cultured yeast fungus in a fine misty form on the stirred rice bran, sufficiently stirring the sprayed rice bran, subsequently subjecting the raw material to the so-called air cutoff fermentation for introducing the raw material into a fermenter kept at a prescribed temperature, heaping up the raw material in the fermenter, beating and hardening the surface, cutting off air from the outside with a nonwoven fabric and a plastic sheet, then hermetically sealing the outside of the fermenter and fermenting the raw material, transferring the raw material to a flat arranging step for performing agitation for shaving off a part of an aerobic state on the surface brought into contact with the air by about 5 cm, placing the shaved off part in the interior when the internal temperature reaches 50 deg.C, passing all the raw material through a process in an anaerobic state once, subsequenty spreading the raw material, exposing the raw material to the air, naturally drying the raw material, then reducing the moisture content to <=10% by mechanical drying at 60 deg.C after the natural drying and providing the product. |
