Novel rice wine fermentation tank

Abstract

The invention provides a novel rice wine fermentation tank which comprises a fermentation tank body, and rice wine fermentation raw materials are contained in the fermentation tank body; the fermentation tank body sequentially comprises a tank body layer, a temperature control layer and a heat preservation layer from inside to outside; the temperature control layer comprises a heating layer and arefrigerating layer, and the heating layer and the refrigerating layer are arranged at intervals in the vertical direction; the adjacent heating layer and refrigerating layer form a temperature control unit; and the heating layer and the refrigerating layer are both communicated with an external heat source and an external cold source through a heat source pipeline and a cold source pipeline. Theheating layers and the refrigerating layers are arranged at intervals in the vertical direction of the fermentation tank body, the adjacent heating layers and refrigerating layers form a group of temperature control units, and when the fermentation tank is used, the groups of temperature control units can be selected to be started according to the fermentation amount of rice wine, so that when thefermentation amount of the rice wine is relatively small, the waste of resources can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of rice wine production and fermentation, and in particular relates to a novel rice wine fermentation tank. Background technique [0002] Rice wine, also known as Jiuniang, sweet wine, was called "Li" in the old days. It is brewed with glutinous rice. It is a traditional specialty wine of the Han nationality and most ethnic minorities in China. The main raw material is Jiangmi, so it is also called Jiangmi wine. Jiuniang is generally called it in the north. It is called "rice wine" or "sweet wine". It is a kind of sweet rice wine fermented with steamed glutinous rice mixed with wine yeast (a special microbial yeast). Its brewing process is simple, the taste is sweet and mellow, and it contains The alcohol content is extremely low, so it is deeply loved by people. my country has a long history of more than one thousand years to make wine with high-quality brown glutinous rice. Rice wine has become a daily drink...

AI Technical Summary

Problems solved by technology

[0003] During the fermentation process of rice wine, regardless of the amount of fermentation, it is placed in the fermenter for fermentation. Since the fermenter is generally relatively large and the temperature control of the fermenter is controlled as a whole, in this case, when the amount of rice wine fermentation is small, the resources will be greatly reduced. The waste is relatively large, and at the same time, during the heat preservation process, the heat preservation temperature of the fermenter cannot be controlled, thereby affecting the fermentation of rice wine, resulting in poor production quality of rice wine
