The Introduction of Solid Sweet Liquor Processing Technology of Geely Rice Wine

2023-09-19

Sweet wine is a kind of traditional flavor food in China, it is sweet and sour delicious, mellow and attractive and favored by the people. Solid sweet wine rehydration is good, flavor and fresh sweet wine can be comparable, greatly extending the preservation life of sweet wine, easy to carry, can be vigorously promoted. Rice wine processing technology of a variety of, Geely rice wine on the introduction of solid sweet wine processing technology. Take a look together. Glutinous rice, sweet wine medicine, citric acid, honey, white wine a little.

Main equipment: pressure cooker, fermentation equipment (with temperature controller), vacuum freeze drying equipment and ancillary equipment.

Process flow: glutinous rice → cleaning → soaking rice → steaming rice → cooling → mixing sweet wine medicine → building a nest → heat preservation fermentation → fresh sweet wine → blending → vacuum freeze drying → finished product

Key points of operation:

Cleaning: Select the best glutinous rice and clean it with tap water to remove dust until the water is clear.

Soaking rice: take glutinous rice washed with clear water and soak in water to make the water surface 10-20cm higher than the rice flour. control the soaking time according to the temperature, usually 6-8 hours in summer and 12-16 hours in winter. grind by hand without hard heart.

Steamed rice: put the rice into a pressure cooker, heat and release the non-condensable gas, and steam for 10 to 12 minutes after boiling. Standard: loose, soft, transparent, no adhesion.

Mix sweet wine medicine: wait for the rice to cool to 35 ℃, add sweet wine medicine with 0.4 ~ 1% rice quantity, and fully stir to mix the rice and medicine evenly.

Heat preservation fermentation: put the above mixture into a constant temperature incubator at 30 ℃, and the juice will be extracted within 24 hours. after 2cm of liquid appears in the nest, the rake will be raised for fermentation, and the fresh sweet wine will be obtained after 3 days.

Add appropriate amount of citric acid, honey and white wine (or not) into the fresh sweet wine according to certain requirements, and send it into the vacuum freeze-drying device. Turn on the vacuum pump to make the indoor pressure 3-7 MPa. At this time, the temperature of the freezing chamber is 12-40 ℃. The fresh sweet wine is quickly frozen to fix the internal water and form uniform and fine ice crystals. Then, under the vacuum of 130-300 Pa, the ice is directly sublimated, and 98% ~ 99% of the water in the material is sublimed from the frozen material.

The color is pure white, the rice grains are clearly visible, and the rehydration is very good.
