Liquid fungus culturing apparatus and liquid fungus culturing method

Abstract

The invention provides a liquid fungus culturing apparatus and liquid fungus culturing method, capable of better performing supply and air exhaust of air inside and outside the tank in the manufacturing process. The liquid fungus culturing apparatus includes: a culture tank, and an aeration device for performing aeration of culture solution in the culture tank, wherein the aeration device has an air pipe for inputting the air to the culture fluid, an exhausting pipe for discharging the air in the culture tank, and a bypass pipe with an opening and closing valve for bypassing the air pipe and the exhausting pipe at the external of the culture tank. The air pipe has a first valve for preventing air flowing during strain inoculating, a second valve for preventing countercurrent of the culture fluid during heating sterilization, and a filter for purification of the inflow air. The exhausting pipe has a pressure gauge, which is provided in a freely knocked-down mode; a third valve and a fourth valve, partitioned with the pressure gauge and configured at both sides of the pressure gauge, and sealing when the pressure gauge is removed.

Description

Technical field [0001] The invention relates to a mushroom liquid strain culture device and a mushroom liquid strain culture method, which is used for cultivating a strain (liquid strain) using liquid as a culture substrate. Background technique [0002] In the artificial cultivation of mushrooms such as Flammulina velutipes, Crab-flavored mushroom, Grifola ash, Pleurotus eryngii, and Pleurotus eryngii, strains are used. Strain refers to a solid medium or liquid medium that uses sawdust or cuttings as the base material to cultivate the secondary hyphae of mushrooms, which makes the operation easier. If you use a plant as a metaphor, it is like a seed. This strain is inoculated into a culture medium, and the mushrooms can be harvested after the mushroom (fruit body) manufacturing process (cultivation process, growth process, cultivation process). [0003] In the production of strains, there are two methods of solid culture and liquid culture, but solid culture is common. However, ...

AI Technical Summary

Problems solved by technology

However, the operation of solid culture is more complicated and time-consuming than liquid culture.

So, that would narrow the space for culturing

In addition, since culture bottles are used to culture the strains, it is necessary to prepare multiple culture bottles, which complicates the handling of the culture bottles

[0004] In addition, in the case of solid culture, it is impossible to confirm whether the strain is good or bad without actually inoculating the strain in the medium and trying to cultivate mushrooms. And even in the case of recovering the bacterial species, it takes time until the recovery

In addition, according to Patent Document 1, since the pressure gauge (54) is not removed, the pressure gauge is easily damaged during heat sterilization.
