Oxygen supply device for cultivating liquid strains of edible fungi

Abstract

The invention relates to the technical field of edible fungi, and discloses an oxygen supply device for cultivating liquid strains of edible fungi. The oxygen supply device comprises a culture box, wherein a rotating shaft is movably connected to the interior of the culture box, an annular rack is fixedly connected to the inner wall of the culture box, and a stirring rod is movably connected to the outer side of the rotating shaft; and a gear is fixedly connected to one side, close to the culture box, of the stirring rod, a center shaft is fixedly connected to the outer side of the rotating shaft and located in the stirring rod, a concave-convex wheel is fixedly connected to the outer side of the center shaft, and a telescopic rod is slidably connected to the interior of the stirring rod. When a culture solution is stirred by the stirring rod, oxygen is released through air outlets uniformly formed in the surface of the stirring rod, so that the contact area of the oxygen and the culture solution is enlarged, and besides, the oxygen is uniformly released in the culture solution and is quickly and sufficiently mixed into the culture solution. The growth speed of the edible fungi is increased, and the culture rate of the edible fungi is increased.

Description

technical field [0001] The invention relates to the technical field of edible fungi, in particular to an oxygen supply device for cultivating liquid strains of edible fungi. Background technique [0002] With the development of science and technology, the fermentation and cultivation technology of edible mushroom liquid strains is becoming more and more mature. Liquid strains have great advantages in the reproduction of strains, the inoculation method of liquid strains, the formula of medium and special equipment. Its fermentation conditions are easy to control, high in activity, less pollution, fast in germination, and low in cost, which can greatly save labor, space and energy consumption. When liquid bacteria are fermented in production fermenters, the dissolved oxygen, temperature stability and The air environment has a great influence on the cultivation of bacteria.

AI Technical Summary

Problems solved by technology

[0003] Edible fungi are all aerobic strains, which need to maintain sufficient oxygen supply during the cultivation process. At present, the conventional edible fungus liquid strain culture tank uses an oxygen machine to meet the oxygen supply requirements of edible fungi, but this oxygen supply The machine can only ensure the stability of oxygen supply in a local area. Due to the relatively high viscosity of the edible fungus culture solution, oxygen is not easy to diffuse in the culture solution, and oxygen cannot be quickly and fully mixed into the culture solution, so that the growth of edible fungi is slow. Affects the growth rate of edible fungi
