The invention provides a yellow rice
wine production technology by mixing
wine with dregs after
fermentation in front fermenting cylinder and front fermenting pot, which comprises the following steps: preparation of rice,
fermentation in front fermenting cylinder,
fermentation in front fermenting pot, fermentation in the back fermenting pot, and preparation of finished product. In the fermentation in the front fermenting cylinder,
yeast for
brewing rice
wine, cooked wine
yeast, raw wine
yeast and rice are added for diastatic fermentation, and in the fermentation in the front fermenting pot, yellow rice wine active dry yeast after activation, raw wine yeast, pure enhanced raw wine yeast, alpha-
amylase, saccharogenic
amylase, acidic
protease and
lactic acid are added for diastatic fermentation, and then two parts of wine with dregs are mixed and added into the back fermenting pot for diastatic fermentation,
protein decomposition, etc.; the invention employs multi-strain and multi-
enzyme system for
biochemistry reaction and wine substance
metabolism, and the invention has the advantages of good
raw material decomposition, complete diastatic fermentation, high liquor yield, short fermentation period and perfect yellow rice wine quality. Most production processes of the present invention employs mechanized line production, thereby realizing effective
automation control of fermentation process, preventing acetification of wine with dregs, improving output and stability of wine, reducing labor intensity and improving production benefit.
