A novel alcohol fermentation system and its application method

Abstract

The invention relates to the field of food processing, in particular to a novel alcohol fermentation system and usage thereof and provides a novel alcohol fermentation system and usage thereof, with this system which is high in extraction efficiency, simple in structure, low in cost, and convenient to operate, allows accurately controlled fermentation temperature and time, is low in alcohol pollution during fermentation and is easy to clean after fermentation. A connecting pipeline is provided with a communicating valve. An upper head of an alcohol fermentation tank is provided with a breather, a gas pressure detector, a feeding valve, a safety valve and a sprinkling system; the breather is provided with a breathing valve used for culturing Saccharomyces cerevisiae in an initial phase of fermentation; the gas pressure detector is used for monitoring pressure of the alcohol fermentation tank; full mixing of skin dregs and juice is facilitated, and extraction efficiency of juice and skin dregs in fermentation is improved.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a novel alcohol fermentation system and its application method. Background technique [0002] At present, the alcohol fermentation tanks used by domestic wine companies are roughly divided into three types, namely, self-made ordinary inclined-bottom tanks, automatic temperature-controlled horizontal rotary tanks and vertical tanks manufactured by imported technology. These three types of alcohol fermentation tanks are still in use in major wine-producing countries abroad. [0003] The advantage of the inclined-bottom alcohol fermenter is that it is cheap and less dependent on mechanical devices, but its disadvantages are also obvious. First of all, there is a lack of effective leaching means. Although various improvements have been made, structural limitations still exist. At the beginning of the fermentation, because the solid and liquid in the grape juice have not been separate...

AI Technical Summary

Problems solved by technology

However, there are also some defects. The tank body of the alcohol tank is relatively deep, and it is not easy to clean after fermentation; the piston rod is used to promote the circulation of the wine, which is time-consuming and laborious, and the piston is easily corroded by alcohol, which shortens the service life of the piston; and the piston is in contact with the wine for a long time. , easy to contaminate wine

During the liquor circulation process, grape seeds are easy to block the spray hole on the center pipe, which reduces the circulation effect of the liquor liquor and affects the fermentation effect
