Technical Field
The utility model relates to a biological fermentation field, concretely relates to improvement of flameless fermentation inoculation device.
Background
In the biological fermentation process, the fermentation process needs a completely clean production to prevent the environmental contamination of the culture. During industrial tank-loading production, slant or dry bacteria powder preserved at low temperature is first activated and enriched in a shake flask, and after reaching certain concentration, the thallus is transferred to a seeding tank for culture. This stage is usually done in a sterile clean laboratory, then transferred to a seed tank, and then scaled up step by step for large-scale production. The production workshops in which the seed culture tanks and the fermentation tanks are located are not sterile and highly clean workshops generally, and the inoculation process from the shake flask of a clean laboratory to the production fermentation tanks needs to ensure that the production fermentation tanks are not infected with bacteria, and a proper sterile operation method needs to be adopted.
In the prior art, in order to ensure sterility, a flame ring rotating method is generally adopted for seed transformation, namely a metal ring with a groove and a handle is used, alcohol cotton is placed in the groove, and the ring is sleeved in a seed transformation opening and is ignited; when the seeds are transferred, the air flow is reduced, the cover of the seed transfer cover is opened, the exhaust valve is closed, and when the pressure of the tank is reduced to be close to zero, the seed liquid is poured into the tank from flame to complete the seed transfer operation. However, there are some problems, such as uneven flame height, even flame extinction, and flying of alcohol cotton due to production, installation failure, or improper operation of alcohol cotton, etc. often occur during the operation, and secondly, open flame cannot be used within 150m in class a workshops or workshops containing class a operation units, which makes it impossible to use the flame ring inoculation method on class a fire-proof-grade fermentation process lines using ethanol or ethyl acetate extraction processes in the post-fermentation treatment processes, or to separately install separate fermentation and separation workshops in a workshop independent of fermentation.
