Anaerobic fermentation device for microecological preparation

Abstract

This utility model discloses an anaerobic fermentation device for microecological preparations, belonging to the field of anaerobic fermentation technology. It includes a base, with a fermentation tank fixedly fitted to the top of the base. The fermentation tank is equipped with a stirring mechanism. A mounting seat is located on the top of the base, and a vacuum pump is fixedly mounted on the top surface of the mounting seat. The input end of the vacuum pump extends into the inner cavity of the fermentation tank, and a one-way valve is fixedly connected to the output end of the vacuum pump. A retaining seat is fixedly connected to the side of the base. In this utility model, when the microecological preparation raw materials are placed into the inner cavity of the fermentation tank for anaerobic fermentation, the vacuum pump extracts the air from the upper part of the fermentation tank's inner cavity, and an air pump draws nitrogen from the inner cavity of a nitrogen tank into the inner cavity of the fermentation tank, filling the upper part of the fermentation tank's inner cavity with nitrogen. This prevents oxygen from affecting the fermentation of the microecological preparation raw materials and ensures the quality of the anaerobic fermentation of the microecological preparation.

Description

Technical Field

[0001] This utility model relates to the field of anaerobic fermentation technology, and more specifically, to an anaerobic fermentation device for a microecological preparation. Background Technology

[0002] Microecological preparations are live microbial preparations made using normal microorganisms or substances that promote microbial growth. In other words, any preparation that can promote the growth and reproduction of normal microbiota and inhibit the growth and reproduction of pathogenic bacteria is called a "microecological preparation." Due to its ability to regulate the intestines and quickly establish intestinal microecological balance, it can prevent and treat diarrhea and constipation in infants, the elderly, and newborn livestock. The activation and fermentation of liquid microecological preparations requires a constant-temperature, sealed environment.

[0003] Utility model patent CN209144166U discloses an anaerobic fermentation device for liquid microecological preparations, which includes a tank, a heating mechanism, and a temperature control mechanism. The upper end of the tank has an inlet, and the tank is equipped with a sealing cap adapted to the inlet. The lower part of the tank has an outlet, and the outlet is equipped with a valve. The heating mechanism includes at least one annular heating element distributed around the circumference of the inner wall of the tank, and the annular heating element is electrically connected to the temperature control mechanism. This anaerobic fermentation device can effectively ferment liquid microecological preparations and maintain a sealed state during the fermentation process, making it less prone to bacterial contamination. It is particularly suitable for the fermentation of liquid microecological preparations in the livestock and poultry farming industry.

[0004] However, the above patents still have the following shortcomings: Anaerobic fermentation is carried out in a low-oxygen or anaerobic environment. When the liquid microecological preparation raw material is not filled into the tank, there is air at the top of the tank. The oxygen in the air can easily affect the quality of anaerobic fermentation. In addition, when the liquid microecological preparation ferments in the tank, the microecological preparation raw material is prone to stratification. At the same time, the microorganisms are not easy to come into good contact with the fermentation agent, which affects the quality of fermentation. Therefore, we have proposed an anaerobic fermentation device for microecological preparations. Utility Model Content
