Yellow rice wine brewing fermentation barrel with cold air stirring and rapid cooling functions and brewing process

Abstract

The invention relates to a yellow rice wine brewing fermentation barrel with cold air stirring and rapid cooling functions and a brewing process. The yellow rice wine brewing fermentation barrel comprises a barrel body and a barrel cover, wherein a discharging pipe is arranged at the bottom of the barrel body and connected with an air inlet pipe; the air inlet pipe is connected with an external air source; a plurality of temperature sensors are arranged on the inner wall of the barrel body; a charging hole is formed in the barrel cover; the discharge pipe at the bottom of the barrel body is mainly used for discharging materials, namely discharging wine after fermentation; the temperature sensors are used for monitoring the fermentation temperature of pulp in the barrel body; and the discharging pipe is connected with the air inlet pipe. When fermentation is conducted, if the temperature rises to be close to a warning line, dry clean cold air is introduced into the barrel body through the air inlet pipe at the moment, the clean cold air can cool the pulp in the barrel body, and meanwhile, the pulp can be stirred, so that pulp cooling is accelerated, and cooling is uniform by pulp stirring; and the clean cold air is used for stirring the pulp, and the pulp can be raked, so that a stirring instrument is omitted, and the pulp is prevented from being adhered to the stirring instrument.

Description

technical field [0001] The invention belongs to the field of brewing, and in particular relates to a rice wine brewing fermenter and a brewing process that is stirred by air-conditioning and rapidly cooled. Background technique [0002] Brewing is the process of using microbial fermentation to produce alcoholic beverages with a certain concentration. There is a process in the middle is fermentation, which is to use yeast to saccharify and wine in the fermentation vessel. [0003] Yeast needs a certain temperature environment during the fermentation process, such as saccharification temperature and cooling temperature requirements. Yeast will generate heat when it works. In order to control the temperature, the fermentation environment needs to be cooled. Most of the existing methods are water cooling to cool down through heat conduction, the cooling speed is slow and the cooling is uneven. [0004] The brewing process is relatively complicated, and the sap is different eve...

AI Technical Summary

Problems solved by technology

[0006] The present invention solves the defects of slow cooling speed, uneven cooling, and influence on the fermentation quality of slurry in the existing brewing using water-cooled heat conduction mode, and provides a rice wine brewing and fermenting vat that is stirred by air-conditioning and rapidly cooled, without water cooling device, The cold air is connected to the bottom of the fermentation tank, and the clean cold air is passed into the fermentation tank from the bottom of the fermentation tank, stirring the slurry in the fermentation tank and quickly acting on the center of the slurry to achieve rapid cooling

[0007] The present invention solves the defect that the stirring equipment needs to be cleaned and dried in the existing brewing, which is easy to cause residues and affects the quality of the next brewing, and provides a rice wine brewing fermenter that is stirred by air-conditioning and quickly cooled down. The bottom of the fermenter is connected with air-conditioning, The cold gas is passed into the fermenter from the bottom of the fermenter to stir the slurry, eliminating the need for stirring equipment and cleaning of the stirring equipment to avoid residues
