A vinegar solid-state brewing all-in-one machine

Abstract

The invention discloses a vinegar solid-state brewing integrative machine. The vinegar solid-state brewing integrative machine comprises a tank body which is of a horizontal rotary cylinder, spiral material turning strips, a through-long filter plate, spray devices, a ventilation pipe and a liquid outlet pipe, wherein a feed inlet is formed in one end of the tank body, and a discharge port is formed in the other end of the tank body, the spiral material turning strips are arranged on the inner wall of the tank body and between the feed inlet and the discharge port, and the ventilation pipe is connected to the tank body; for the fermentation site of the tank body, the through-long filter plate is arranged above the inner bottom of the tank body, and a cavity is formed between the through-long filter plate and the bottom of the tank body, the spray devices are arranged in the tank body and above a solid fermentation substrate of vinegar, and the liquid outlet pipe is arranged at the bottom of the tank body. By adopting the vinegar solid-state brewing integrative machine disclosed by the invention, vinegar solid-state brewing and vinegar spraying operations are integrated to realize multi-functionalization of the same equipment so as to shorten the fermentation period of the vinegar, ensure that the vinegar has a good flavor, improve the productivity of vinegar and facilitate equipment automation and high intelligent degree.

Description

technical field [0001] The invention belongs to the field of food processing equipment, in particular to fermentation and vinegar-drenching equipment for solid-state fermentation of vinegar. Background technique [0002] There are many types of microorganisms involved in solid fermented vinegar, and the product flavor is better, so it is more and more favored by people. [0003] At present, the main production method in the vinegar solid-state brewing industry is still the fermentation tank, but there are also some fermentation equipment used in the vinegar fermentation process. The most representative fermentation equipment is the horizontal drum fermentation tank and the vertical reflux fermentation tank. Both have improved the mechanization level and production efficiency of vinegar brewing to varying degrees. But at the same time, both have their own defects: the horizontal drum fermenter can be turned over by rotation. Although it can carry out the solid-state fermenta...

AI Technical Summary

Problems solved by technology

But at the same time, both have their own defects: the horizontal drum fermenter can be turned over by rotation. Although it can carry out solid-state fermentation of vinegar, it cannot realize the vinegar drenching operation with the same equipment. It needs to transfer materials to do the vinegar drench operation. Low efficiency and other problems; the vertical reflux fermenter uses vinegar brine circulation instead of turning the fermented grains to achieve the purpose of cooling and increasing oxygen, but the long-term reflux causes the vinegar grains to harden, making the fermentation uneven, and the dissolved oxygen in the vinegar grains is insufficient, resulting in a fermentation cycle. Long and poor product quality and other issues

[0004] In some places and in the fermentation process of solid-state fermentation equipment, the alcohol content of vinegar grains is relatively large, generally as high as 70%. Excessive alcohol content will affect the increase of fermentation temperature and the dissolved oxygen of vinegar grains. Improving the fermentation temperature of the bottom vinegar grains and the ventilation and looseness of the whole vinegar grains to ensure the fermentation and flavor of vinegar are also problems that need to be solved at present
