Embodiment 1
[0034] A kind of raw material liquid fermentation process of the present embodiment produces liquor-based liquor, comprising the following steps:
[0035] (1) Expand and activate Saccharomyces cerevisiae to make the cell concentration reach 2×10 8 a / mL;
[0036] (2) After the rice is ground into rice flour, it flows into the stirring device with water according to the mass ratio of 1:3, and stirs evenly to obtain rice milk;
[0037] (3) Put 200 tons of rice milk into 250m2 together with expanded and activated Saccharomyces cerevisiae and glucoamylase 3 During the feeding process, 25L / min of CO was introduced from the bottom of the fermenter while stirring. 2 Mix the materials evenly, and continue to feed CO after the feeding is completed. 2 15min to obtain homogenized fermented mash;
[0038] (4) The fermented mash after step (3) was processed and fermented for 4 days. After 36 hours of fermentation, 25 L / min of CO was introduced from the bottom of the fermenter again. 2 ...
Embodiment 2
[0048] A kind of raw material liquid fermentation process of the present embodiment produces liquor-based liquor, comprising the following steps:
[0049] (1) Expand and activate Saccharomyces cerevisiae to make the cell concentration reach 2×10 8 a / mL;
[0050] (2) After the rice is ground into rice flour, it flows into the stirring device with water according to the mass ratio of 1:3, and stirs evenly to obtain rice milk;
[0051] (3) Put 200 tons of rice milk into 250m2 together with expanded and activated Saccharomyces cerevisiae and glucoamylase 3 During the feeding process, 25L / min of CO was introduced from the bottom of the fermenter while stirring. 2 Mix the materials evenly, and continue to feed CO after the feeding is completed. 2 5min to obtain homogenized fermented mash;
[0052] (4) The fermented mash after the step (3) was processed was sealed and fermented for 6 days. After 30 hours of fermentation, CO was introduced from the bottom of the fermenter again. ...
Embodiment 3
[0062] A kind of raw material liquid fermentation process of the present embodiment produces liquor-based liquor, comprising the following steps:
[0063] (1) Expand and activate Saccharomyces cerevisiae to make the cell concentration reach 2×10 8 a / mL;
[0064] (2) After the rice is ground into rice flour, it flows into the stirring device with water according to the mass ratio of 1:3, and stirs evenly to obtain rice milk;
[0065] (3) Put 200 tons of rice milk into 250m2 together with expanded and activated Saccharomyces cerevisiae and glucoamylase 3 During the feeding process, 25L / min of CO was introduced from the bottom of the fermenter while stirring. 2 Mix the materials evenly, and continue to feed CO after the feeding is completed. 2 10min to obtain homogenized fermented mash;
[0066] (4) The fermented mash after the step (3) was processed was sealed and fermented for 5 days, and after 34 hours of fermentation, CO was introduced from the bottom of the fermenter aga...
