Slow oxygen-releasing fermentation tank for liquid strains of edible fungi

Abstract

The invention discloses a slow oxygen-releasing fermentation tank for liquid strains of edible fungi, and relates to the field of edible fungus production equipment. The fermentation tank comprises atank body the top of which is provided with a feeding port and an exhaust one-way valve; the bottom of the tank body is provided with a material outlet and a gas inlet pipe, and the gas inlet pipe iscommunicated with the tank body and provided with an air inlet one-way valve; the top of the tank body is provided with a driving motor, an output shaft of the driving motor is connected with a stirring rod extending into the tank body, and the surface of the stirring rod is provided with concave pits and bulges; the fermentation tank also comprises nutrient granules entering the fermentation tankalong with gas, the shells of the nutrient granules can be dissolved in the nutrient compositions of the liquid strains, and the nutrient granules are filled with oxygen. By means of the fermentationtank, the problem is solved that internal hypoxia of mycelium is caused due to insufficient nutrients in the later period of the fermentation of the liquid strains; the fermentation tank is mainly used for slowly and continuously supplementing nutrients needed for the whole growth process of the edible fungus bodies and the oxygen needed for respiratory metabolism.

Description

technical field [0001] The invention relates to the field of edible fungi production equipment, in particular to a slow-release oxygen-releasing liquid edible fungus fermenter. Background technique [0002] Edible fungus liquid strains are edible fungus strains in liquid form produced by liquid fermentation technology in a liquid medium in a fermenter tank. Liquid strains are prepared by modern biological fermentation technology. Compared with solid strains, they are quite The biggest advantage is that it has fast seed production, strong vitality, less pollution, fast germination, low cost, and can save labor, space and energy consumption. At present, the edible fungi that can be fermented in our country include: Agaricus bisporus, Stropharia stropharii and Lentinus edodes. [0003] The edible fungus fermenter is a fermentation facility equipment used for the production of edible fungi mycelium to cultivate liquid strains. It uses the principle of biological fermentation to...

AI Technical Summary

Problems solved by technology

[0007] 1. The hyphae of edible fungi continuously absorb the nutrients and oxygen in the nutrient solution, so that the nutrients and oxygen in the nutrient solution are continuously reduced, resulting in nutrient deficiency in the later stage, and causing hypoxia inside the mycelium, which affects the The formation of bacterial balls, the number of bacterial balls decreased sharply

[0008] 2. When the stirring device in the tank is in use, it is easy to have bad phenomena such as uneven stirring, and the amount of dissolved oxygen in the nutrient solution is small, which affects the growth of liquid bacteria

[0009] 3. The oxygen consumption required by mycelium is large, and the time for the feeding machine to feed oxygen into the liquid bacteria is longer, thus increasing the power consumption of the feeding machine
