Description

Technical Field

[0001] The present invention relates to the technical field of rice wine brewing, and particularly relates to a pressure filtration device for brewing rice wine and a using method thereof. Background Art

[0002] Rice wine, also known as fermented glutinous rice wine or sweet wine, was formerly called "Li". Its brewing process is simple, and the taste is sweet, mellow and delicious. The alcohol content is extremely low, so it is deeply loved by people. Rice wine has become a daily beverage for farmers. When making it, glutinous rice is brewed. Cooked glutinous rice is added with distiller's yeast and fermented. The rice grains are filtered out to get rice wine, while the fermented glutinous rice with grains is not filtered. It can be heated and served with small glutinous rice balls as a snack, with a slightly sour, slightly sweet and alcoholic taste.

[0003] The modern production process of rice wine is as follows: Wash the glutinous rice clean, soak it in cold water for 4 - 5 hours. Place a clean cloth on the steamer, and directly place the glutinous rice on the cloth and steam it. Put the steamed rice in a clean basin. When the temperature drops to 30 - 40 degrees, mix in distiller's yeast in proportion, dig a hole in the middle, then sprinkle some cooled boiled water on the glutinous rice, cover it, and place it in a place with a temperature of more than 20 degrees. After about 30 hours, it will give out a flavor.

[0004] Of course, for slightly better rice wine, it generally needs to be filtered and purified, that is, the rice wine and the distiller's grains in the rice wine mixture are separated, the sweetness is reduced, and the alcoholic taste is increased, which is more suitable for people who like to drink. Since part of the rice wine is adsorbed in the solid distiller's grains, usually the pressure filtration method is adopted for solid-liquid separation. By applying a certain pressure, the efficiency of solid-liquid separation is improved, and thus the wine yield of rice wine production is increased.

[0005] The pressure filtration devices in the prior art usually adopt a simple extrusion separation technology, so that the pressures on the upper, middle and lower parts of the rice wine mixture are different. The rice wine mixtures in each layer are still in their original areas after multiple pressure filtrations, resulting in that after the pressure filtration is completed, part of the distiller's grains still adsorb rice wine, thus there are problems of incomplete pressure filtration and low wine yield of rice wine. Summary of the Invention

[0006] The embodiment of the present invention provides a pressure filtration device for brewing rice wine and a using method thereof, which can solve the problem in the prior art that the rice wine mixtures are still in their original areas after multiple pressure filtrations, resulting in that after the pressure filtration is completed, part of the distiller's grains still adsorb rice wine, thus there are problems of incomplete pressure filtration and low wine yield of rice wine.

[0020] A pressure filtration method for brewing rice wine includes the following steps:

[0021] S1: After placing the rice wine mixture to be pressure-filtered in the pressure filtration box, the opening of the pressure filtration box is sealed by a sealing plate.

[0022] S2: The driving mechanism drives the sliding rod to perform vertical reciprocating motion, continuously hitting the force-bearing rod. The force-bearing rod drives the pressure filtration plate to move upward to squeeze the rice wine mixture, separating the distiller's grains from the rice wine. During the lifting and lowering process of the force-bearing rod, due to the elastic potential energy of the first elastic member and the second elastic member, the pressure filtration plate is constantly in a vibrating state, disrupting the original structural hierarchy of the rice wine mixture. During the downward movement of the force-bearing rod, the dispersion plate on the ramming rod rotates and inserts into the pressure filtration box to further disperse the rice wine mixture. During the upward movement of the force-bearing rod, the dispersion plate on the ramming rod rotates and withdraws.

[0023] S3: Repeat S2 multiple times until the distiller's grains and the rice wine are completely separated.

The driving mechanism drives the sliding rod to perform vertical reciprocating motion, so that the sliding rod continuously hits the force-bearing rod. The force-bearing rod drives the pressure filtration plate to move upward to squeeze the rice wine mixture. The rice wine passes through the filter cloth and the filter holes to be separated from the distiller's grains. During the lifting and lowering process of the force-bearing rod, due to the elastic potential energy of the first elastic member and the second elastic member, the pressure filtration plate is constantly in a vibrating state, disrupting the original structural hierarchy of the rice wine mixture. After multiple squeezes, the distiller's grains and the rice wine are completely separated after the pressure filtration is completed, improving the liquor yield of the rice wine.
