Rapid fermentation culture dish for lactic acid bacteria

Abstract

The invention relates to the technical field of culture dishes, in particular to a rapid fermentation culture dish for lactic acid bacteria. The rapid fermentation culture dish comprises a cleaning mechanism, a valve mechanism, a covering mechanism and a water drainage mechanism. Some water vapor generated in the process of culturing lactic acid bacteria is adsorbed in the culture dish, the cleaning mechanism drives a brush strip to clean water vapor attached to the bottom end of a dish cover by rotating a first rotating shaft, when certain water vapor attached to the inner side wall of the dish bottom falls into a first leakage groove, a rubber block is driven to move downwards by rotating the first rotating shaft, then water in the first leakage groove falls into a water tank, when the dish cover is closed, a protruding block can be extruded to slightly clamp the dish cover, an inclined sliding block can be extruded to drive a piston to block the bottom end of the water tank while the dish cover is closed, when the dish cover is opened, a third spring can push the piston to reset so as to enable a second leakage groove to coincide with the water tank, then water in the water tank can flow to a third leakage groove through the second leakage groove, and finally, the water flows out of the culture dish through the third leakage groove.

Description

technical field [0001] The invention relates to the technical field of culture dishes, in particular to a rapid fermentation culture dish for lactic acid bacteria. Background technique [0002] A petri dish is a kind of experimental vessel used for microorganism or cell culture. It consists of a flat disc-shaped bottom and a cover. It is generally made of glass or plastic. Glass can be used for plant materials, microbial culture and animal cells. Adhesive culture may also be used. The plastic may be made of polyethylene material. There are disposable and multiple-use ones. It is suitable for laboratory inoculation and streak separation of bacteria, and can be used for the cultivation of plant materials. [0003] At present, the petri dish on the market encounters water vapor attached to the inner side wall during use, which requires opening the petri dish to wipe the inside, so that the field of view is clearer when observing the petri dish, but the inside of the petri dish ...

AI Technical Summary

Problems solved by technology

[0003] At present, the petri dish on the market encounters water vapor attached to the inner side wall during use, which requires opening the petri dish to wipe the inside, so that the field of view is clearer when observing the petri dish, but the inside of the petri dish is opened The environment will change, which will affect the fermentation of lactic acid bacteria in the petri dish. The water vapor generated during the fermentation of lactic acid bacteria should be collected and processed to prevent the colonies from being washed out and affect the experimental results.
