Description

Technical Field

[0001] The utility model relates to the technical field of liquor brewing, in particular to an anaerobic microorganism inoculation tank used for liquor brewing. Background Art

[0002] Currently, Luzhou-flavor liquor is typically brewed in mud pits. Over the years, the microorganisms in the mud have been domesticated and enriched during the brewing process. These microorganisms are primarily anaerobic. Anaerobic bacteria in the mud break down macromolecules (starch, protein, and fat) during the brewing process, allowing them to grow and metabolize, producing the precursors of Luzhou-flavor liquor's flavor compounds, such as acetic acid, propionic acid, butyric acid, and hexanoic acid.

[0003] Currently, although workers have isolated and obtained anaerobic microorganisms with various functions from the pit mud, the flux obtained is relatively small. They need to be cultured and propagated in an inoculation tank to further amplify the flux in order to meet process requirements. After the culture is completed, the seed liquid in the inoculation tank is introduced into the fermentation tank. Existing inoculation tanks usually have an inoculation port at the top, which is equipped with a sealing cap for sealing. The inoculation tank has a connection port at the bottom, which is equipped with a connecting pipe. The inoculation tank is connected to the fermentation tank through the connecting pipe. This device uses the liquid level difference between the fermentation tank and the inoculation tank to introduce the seed liquid from the inoculation tank into the fermentation tank. The seeding speed is slow, affecting the inoculation efficiency. Utility Model Content

[0004] In order to solve the technical problem of low inoculation efficiency in the prior art, the utility model provides an anaerobic microbial inoculation tank for liquor brewing, which prevents the fermentation tank from being contaminated by miscellaneous bacteria and has high inoculation efficiency. The gas generated by the bacteria inside the inoculation tank during the cultivation process is used to form a pressure difference between the inoculation tank and the fermentation tank, thereby increasing the inoculation speed. In addition, the first stop valve is adjusted to allow the inoculation tank to ventilate the fermentation tank, so that a relatively high-pressure environment is formed in the fermentation tank, thereby preventing miscellaneous bacteria in the air from entering the fermentation tank during inoculation.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] An anaerobic microbial inoculation tank for liquor brewing comprises a tank body, an inoculation port is provided on the top of the tank body, the inoculation port is equipped with a sealing cover for sealing, a first connecting port is provided at the bottom of the tank body, and the tank body also comprises a first connecting pipe, one end of the first connecting pipe is sealedly connected to the first connecting port, and the other end of the first connecting pipe is used to introduce bacterial liquid into the equipment to be inoculated, a second connecting port is provided on the upper part of the tank body, and the tank body also comprises a second connecting pipe, a first stop valve is provided on the second connecting pipe, one end of the second connecting pipe is sealedly connected to the second connecting port, and the other end is installed with a first quick-release connector, and the second connecting pipe is used to connect to the upper part of the equipment to be inoculated.

[0007] Furthermore, a second stop valve is provided on the first connecting pipe, and a second quick-release connector is installed on the other end of the first connecting pipe.

[0008] Furthermore, the first connecting pipe and the second connecting pipe are both rubber hoses.

[0009] Furthermore, a sampling port is provided on the tank body, and a needle valve is installed on the sampling port.

[0010] Furthermore, a handle is provided on the top of the tank body.

[0011] Furthermore, a support seat is provided at the bottom of the tank body.

[0012] Furthermore, an arc structure is used to transition between the bottom wall and the side wall inside the tank.

[0013] The beneficial effects of the utility model are:

[0014] 1. The present application provides an inoculation tank that prevents contamination of a fermentation tank by miscellaneous bacteria and has a high inoculation efficiency. The gas generated by the bacteria inside the inoculation tank during the cultivation process creates a pressure difference between the inoculation tank and the fermentation tank, thereby increasing the inoculation speed. In addition, the first stop valve is adjusted to allow the inoculation tank to pass gas into the fermentation tank through the second connecting pipe, creating a relatively high-pressure environment in the fermentation tank, preventing miscellaneous bacteria in the air from entering the fermentation tank during inoculation, and ensuring the safety of inoculation. The first stop valve and the second connecting pipe can also relieve pressure in the inoculation tank to prevent excessive pressure in the inoculation tank, which poses a safety hazard.

[0015] 2. A second shut-off valve is installed on the first connecting pipe, and a second quick-release connector is installed on the other end of the first connecting pipe. The second quick-release connector allows for quick and convenient connection and disconnection of the pipe, which is very useful when frequent connections or maintenance are required. The second shut-off valve provides precise control of the liquid flow.

[0016] 3. The rubber hose has good pressure resistance and a certain degree of bending, making the connection more flexible and convenient. In addition, the hose is easy to install and disassemble. In actual application, the position or length can be adjusted according to the actual situation, which enhances the adaptability of the system.

[0017] 4. The sampling port design allows staff to obtain samples without destroying the closed system to monitor parameters such as the environmental status or microbial activity in the inoculation tank. The needle valve provides the possibility of precise control of the sampling volume, reducing the risk of external contamination.

[0018] 5. The presence of the handle greatly improves the safety and convenience during transportation, especially when the inoculation tank needs to be moved to different locations or for cleaning and maintenance.

[0019] 6. The design of the support base enables the inoculation tank to be placed stably, avoiding problems such as tipping due to instability. At the same time, it also prevents the bottom of the tank from contacting the ground, protecting the bottom of the tank and facilitating the setting of the first connection port, making it easy to completely drain the bacterial liquid in the tank.

[0020] 7. The bottom wall and side wall inside the tank are treated with a smooth structural transition, which helps to reduce dead corners and make the tank more thoroughly clean, which is conducive to maintaining good sanitary conditions and preventing bacterial growth, thereby improving product quality stability.
