AI Technical Summary

Technical Problem

Common pre-fermentation devices of rice wine lack defoaming structure and cannot process the foam during pre-fermentation of rice wine, causing the mash to spill out of the tank in a spray-like manner.

Method used

A pre-fermentation and defoamer of rice wine is designed, including air-feeding defoamer and rotary drive assembly. The air supply defoaming assembly transports air into the mash through components such as air pump, filter cartridge, ventilation pipe and exhaust defoaming pipe to eliminate air bubbles. The rotary drive assembly drives the defoaming assembly to rotate and improves the defoaming efficiency by driving the motor and the transmission belt.

Benefits of technology

Effectively eliminate the bubbles generated by the mash, prevent the mash bubbles from overflowing during the fermentation process of the rice wine, solve the problem that common devices cannot handle the foam, and improve the safety and efficiency of the rice wine brewing.

Abstract

The utility model relates to the technical field of yellow rice wine production, in particular to a yellow rice wine pre-fermentation defoamer. The technical problems that a common yellow rice wine pre-fermentation device lacks a defoaming structure, foam cannot be treated in the yellow rice wine pre-fermentation process, a large amount of foam is generated by saccharified mash dextrin, and mash overflows out of a tank in a spraying mode are easily caused are solved. According to the technical scheme, the yellow rice wine pre-fermentation defoaming device comprises a tank body. According to the utility model, the air supply defoaming assembly is matched with the rotary driving assembly, so that bubbles generated by mash can be eliminated in the pre-fermentation process of the yellow wine, and mash bubbles are prevented from overflowing in the pre-fermentation process of the yellow wine, thereby solving the problems that a common yellow wine pre-fermentation device is short of a defoaming structure, and the production cost is low. The problems that foams cannot be treated in the pre-fermentation process of the yellow rice wine, a large amount of foams are generated by saccharified mash dextrin, and mash overflows out of a tank in a spraying manner are solved.
