Technical field
Microbial fermentation equipment technical field is the utility model is related to, more particularly to a kind of Double shaft stirring fermentation tank.
Background technology
Fermentation tank, refer to the industrial device for being used for carrying out microbial fermentation.Its main body is generally made of stainless steel plate
Main formula cylinder, its volume is in 1m3 to hundreds of m3.It is in design and processing it should be noted that vertebration, rationally.Steam is resistant to go out
Bacterium, there are certain operating flexibility, contents to reduce as far as possible(Avoid dead angle), material and energy transmission performance it is strong, and one can be carried out
Surely it is adjusted so that cleaning, reduces pollution, is suitable for the production of multiple product and reduces energy expenditure.For anaerobic fermentation
The fermentation jar structure of (such as production alcohol, solvent) can be simpler.For aerobic fermentation (such as production antibiotic, amino acid, organic
Acid, vitamin etc.) fermentation tank because need to continuously be passed through a large amount of filtrated airs into tank, and to consider to be passed through the utilization rate of air,
Therefore it is complex on fermentation jar structure, conventional has mechanical stirred-tank fermenter, bubbling fermentation tank and airlift fermentor.
Dairy products, wine fermentation process are a sterile, free of contamination processes, and fermentation tank employs sterile system, avoids and prevent
The pollution of microbes in air, substantially prolongs product shelf-life and product it is pure, be specifically designed on tank body and be mounted with nothing
Bacterium breathes stomata or sterile malleation fermentation system.Tank body is provided with rice Lip river plate or labyrinth type chuck, can be passed through and Jie is heated or cooled
Matter carries out circulating-heating or cooling.The capacity of fermentation tank is by more kinds of different sizes of 300-15000L.Fermentation tank presses use range
