Description
Technical Field
[0001] This utility model belongs to the field of liquor fermentation technology, specifically relating to a pure grain solid-state fermentation liquor device. Background Technology
[0002] In the field of baijiu (Chinese liquor) brewing, the pure grain solid-state fermentation process is highly favored for its unique flavor and high quality. However, the traditional fermentation equipment currently in use has certain drawbacks in practical applications, such as the difficulty in cleaning the inner walls of the fermentation tanks. Due to the structural limitations of the fermentation tanks, there is a lack of specialized and efficient cleaning devices, requiring a significant amount of manpower, resources, and time for each cleaning. Furthermore, if residual lees and other impurities are not thoroughly cleaned, bacteria and other harmful microorganisms can easily proliferate. These microorganisms can negatively impact the quality of baijiu during subsequent fermentation, such as altering its taste and causing spoilage, severely hindering the development of baijiu production enterprises. Utility Model Content
[0003] The purpose of this invention is to provide a pure grain solid-state fermentation device for baijiu (Chinese liquor) to solve the problem of inconvenient cleaning of the inner wall of the fermentation tank mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a pure grain solid-state fermentation baijiu device, comprising a support base, a support plate, and a fermentation tank. The support plate is rotatably connected to the support base via a hinge. Two hydraulic cylinders are installed on the bottom wall of the inner cavity of the support base. Two fixing plates that are fixedly connected to the fermentation tank are symmetrically fixed on the surface of the support plate. A rotary motor is installed on the outer wall of one of the fixing plates.
[0005] The output end of the rotary motor is fixed with a rotating shaft. Multiple stirring paddles are fixed on both outer walls of the rotating shaft, and two fixing columns are fixed on both outer walls of the rotating shaft. A fixing box is fixed on one outer wall of the fixing column, and a scraper that fits against the inner wall of the fermentation tank is movably connected to one outer wall of the fixing box.

[0030] Working principle:
[0031] Before brewing, the pure grain solid-state fermentation baijiu device injects an appropriate amount of clean water into the fermentation tank 5. The rotating motor 6 drives the fixed box 10 and scraper 15 to rotate. The support spring 13 makes the scraper 15 stick to the inner wall of the fermentation tank 5 to scrape off impurities. After cleaning, the hydraulic cylinder 3 is started, which makes the support plate 2 tilt the fermentation tank 5. The dirt is discharged from the discharge pipe 19. The pre-treated pure grain solid raw materials are put into the fermentation tank 5 through the feed hopper 17. The rotating motor 6 is started, which drives the rotating shaft 7 and the stirring paddle 8 to rotate, which fully turns the raw materials, so that the fermentation raw materials are in full contact with microorganisms, accelerates fermentation, and increases the fermentation speed.
[0032] After fermentation is complete, the sealing cap on the discharge pipe 19 is opened, and the mixture of wine and lees flows out. The filter screen inside the filter plate 20 intercepts impurities, achieving separation of wine and impurities and ensuring the quality of the liquor. The filter plate 20 can be easily disassembled and assembled via the handle 21. At the same time, during the process of discharging the wine, the rotating motor 6 drives the scraper 15 to rotate, which can scrape off the impurities on the filter plate 20 and prevent the filter plate 20 from clogging.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
