AI Technical Summary

Technical Problem

Existing horizontal fermentation tanks have difficulty achieving vertical displacement of vinegar mash during the turning process, resulting in uneven turning, dead corners, and vinegar mash adhering to the inner wall of the tank, which affects the fermentation effect.

Method used

A horizontal rotary fermentation tank is adopted, with the first and second scrapers connected to a fixed shaft. The first scraper scrapes off the upper layer of vinegar mash, and the second scraper scrapes off the inner wall of vinegar mash. Combined with a length adjustment mechanism and a spring compensation structure, the vinegar mash is ensured to be turned evenly and dead corners are avoided.

Benefits of technology

To achieve uniform turning of the vinegar mash, improve fermentation quality, avoid dead corners in the turning process, and enhance product stability and raw material utilization.

Abstract

The utility model discloses a kind of vinegar fermentation tanks, belong to edible vinegar production equipment technical field, including tank body, the tank body is horizontal rotary fermentation tank, the fixed shaft of tank body is along axis and is connected with its rotation, the first scraper and second scraper extending along its axial direction are equipped in the tank body, the first scraper and second scraper are connected with fixed shaft respectively, the first scraper is spaced from tank body inner wall, and first scraper is used to scrape off upper layer vinegar fermentation, the second scraper is contacted with tank body inner wall, and the second scraper is used to scrape off vinegar fermentation on tank body inner wall, along the rotation direction of tank body, the second scraper is located in the rear side of first scraper. The utility model uses first scraper to cut into upper layer vinegar fermentation and strip off it and drop, simultaneously using second scraper to remove the vinegar fermentation remaining in tank body inner wall, both synergistically promote upper and lower layer vinegar fermentation replacement, improve uniformity of turning vinegar, and it is beneficial to uniform fermentation of vinegar fermentation.
