Description
Technical field
This utility model relates to a kind of low pressure fermentation tank.
Background technology
During heat aerobic organisms fermentation, the supply of oxygen is a key factor, to the growth of thalline and metabolite
Accumulation all has a great impact.In oxygen system, the air sparger of fermentation tank has the biggest importance.Air sparger
Advanced Degree of Accord Relation to the electric power energy consumption of fermentation, the consumption of air, fermentation dissolved oxygen situation, and then affect fermentation index
Quality.
The fermentation tank that China fermentation industry uses be mostly the drawing that the fifties, the former Soviet Union provided be the logical of general source
With fermentation tank, generally there is energy consumption big, molten oxygen is low, and low thing conversion ratio is low, and equipment life is short.Product cost cannot be reduced, strengthen
Enterprise competitiveness.Traditional Ping Yeshi that China's fermentation tank is conventional, curved blade type, the disc turbine agitator such as arrow leaf formula, mostly use
Be multi-layer phase with radial type agitator, but overall cyclicity is poor, power consumption is big.
Summary of the invention
This utility model purpose is to solve the deficiencies in the prior art, it is provided that a kind of mixing effect is good, service life is long
Low pressure fermentation tank.
This utility model solves problem and the technical scheme is that a kind of low pressure fermentation tank, including tank body, described tank body
