PURPOSE: To accomplish the process simplification for fermentation by saccharification through such processes that the first tank is charged with raw materials followed by transferring the materials into plural tanks arranged in parallel, and the materials are left to stay for a specified time in each of the tanks, thereby producing saccharified unrefined soy in a simple manner.
CONSTITUTION: Raw materials heat-treated in a boiler 131 are transferred through a pump 121 into a tank 101. Powdery sub-materials in vessels 112-117 and liquid sub-materials in a vessel 111 are also fed into the tank 101, and the raw materials thus combined are agitated and held for a specified time, and then transferred, using a pump 123, into saccharification tanks 102-106 where the materials are held again for a specified time and saccharified, thus obtaining the objective saccharified unrefined soy.
