Description

Technical Field

[0001] The utility model relates to the technical field of bacterial strain culture equipment, in particular to a uniformly mixed liquid bacterial fermentation bacterial strain culture equipment. Background Art

[0002] Liquid strains refer to mycelium grown in liquid culture medium. In industry, the process of making liquid strains is called deep fermentation. Many strains need to be cultured in fermentation tanks. During the fermentation process, oxygen needs to be regularly introduced into the fermentation tanks. However, it is not easy for existing fermentation tanks to fully mix oxygen and liquid bacteria, which affects the fermentation efficiency. For example, in a rapid fermentation tank for liquid strains of edible fungi recorded in the patent announcement number CN 217578867 U, oxygen is transported into the gas pipe through a gas transmission device. Oxygen enters the branch pipe, causing the air pressure in the branch pipe to increase, thereby pushing the inner pipe outward, driving the retaining ring to squeeze the second spring, thereby opening the through hole on the surface of the branch pipe and transporting oxygen to various parts of the fermentation tank. However, the fermentation tank lacks a stirring mechanism, so that the oxygen, nutrients, liquid bacteria and other substances inside the fermentation tank cannot be evenly mixed, and the fermentation tank is in a sealed state, so that the oxygen cannot drive the inner pipe to move under the action of air pressure, and thus the oxygen injection operation cannot be completed.

[0003] Based on this, a uniformly mixed liquid bacteria fermentation strain culture device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content
