Description

Technical Field

[0002] In the rice wine production process, the rice water mixture is pumped into the rice soaking tank through rice lifting, and soaked in the rice soaking tank for a period of time to promote the hydrolysis of starch, in preparation for the subsequent saccharification and fermentation process.
