Edible fungi liquid strain biological fermentation tank

Abstract

The invention discloses an edible fungi liquid strain biological fermentation tank, which comprises a tank body of which the top is provided with a feed port. The edible fungi liquid strain biological fermentation tank is characterized in that: a conical lower sealing head is arranged on the lower part of the tank body; an air inlet is formed at the bottom of the lower sealing head; an air inlet pipe is connected to the air inlet; a baffle is fixedly arranged on the lower sealing head above the air inlet; and an air passage is formed between the baffle and an inner wall of the lower sealing head or is formed on the baffle. When the edible fungi liquid strain biological fermentation tank is used for fermenting liquid strains, clean air or oxygen enters the tank body from the air inlet at the bottom of the lower sealing head through the air inlet pipe under certain pressure. Due to blockage and air distribution functions of the baffle, clean gases with certain pressure uniformly enter the tank body from the air passage, and the gases move from bottom to top. Therefore, the edible fungi liquid strain biological fermentation tank can realize effective and uniform oxygen supply, has the non-destructive aerodynamic mixing function, and replaces a hard mixing device in the prior art. The edible fungi liquid strain biological fermentation tank has the advantages of simple and reasonable structure, convenient use, uniform oxygen supply and mixing, and good fermentation effect on the liquid strains.

Description

technical field [0001] The invention relates to a fermenter, in particular to a biological fermenter for edible fungus liquid strains. Background technique [0002] The edible fungus liquid strain bio-fermentation tank in the prior art includes a flat-bottomed tank body, a feed inlet is provided on the top of the tank body, a hollow stirring rod extends into the tank from the top of the tank body, and an air outlet is provided at the end of the hollow stirring rod . During the biological fermentation of edible fungus liquid strains, the tank is filled with clean air or oxygen through the hollow stirring rod, and then stirred when necessary. The defects of this kind of edible fungus liquid strain biological fermentation tank are: 1. It is difficult to operate the hollow stirring rod according to the installation, and because the position of the hollow stirring rod after installation is limited, the stirring effect is poor and uniform mixing cannot be achieved. Stirring in t...

AI Technical Summary

Problems solved by technology

The defects of this kind of edible fungus liquid strain biological fermentation tank are: 1. It is difficult to operate the hollow stirring rod according to the installation, and because the position of the hollow stirring rod after installation is limited, the stirring effect is poor and uniform mixing cannot be achieved. Stirring in the tank; and the stirring through the hollow stirring rod is a hard stirring method, which will cause damage to the mycelia to a certain extent; 2. It adopts the way of upper air intake, which causes the gas to enter the tank unevenly, so that the liquid strain of bacteria Uniform oxygen supply cannot be achieved during biological fermentation
