Embodiment 1
[0028](1) Liquefaction of raw materials: Take 1000kg of rice, add 1500kg of water, soak for 6 hours, and grind it into slurry by grinding wheel.
[0029] (2) Alcoholic fermentation: Add 3kg of amylase to the slurry, raise the temperature to 92°C, keep it warm for 15 minutes, boil it, and pump it into the alcohol fermentation tank. Add water to adjust the concentration to 9.5°Bé and adjust the temperature to 32°C. Add 2.4 kg of 50,000 units / g of glucoamylase and 2 kg of active dry yeast, mix well, and ferment at 30-34°C for 5 days.
[0030] (3) Plate and frame filter press: the fermented wine mash is filtered through a plate and frame to obtain sake liquid.
[0031] (4) Acetic acid fermentation: add water to the above-mentioned sake liquor to adjust the alcohol content to 6.5% (v / v), insert 800kg of acetic acid bacteria (AS1.41), and spray the filler system made of non-woven fabrics intermittently after sterilization On the top, let the filling material absorb a large amount ...
