Description

Technical Field

[0001] The utility model belongs to the technical field of fermentation equipment, and in particular relates to a corn steep liquor fermentation tank. Background Art

[0002] Corn pulp can be obtained by crushing and fermenting corn. It contains rich nutrients such as amino acids, organic acids, soluble sugars, vitamins and metal salts. It can be used as an important raw material for the production of culture media such as antibiotics and provides a natural organic nitrogen source for microbial growth.

[0003] The processing of corn slurry requires the use of fermentation tanks, during which oxygen, fermentation bacteria and other additives need to be introduced. Since corn slurry is relatively thick, it needs to be constantly stirred during fermentation to ensure that the corn slurry in the fermentation tank can be evenly mixed with the additives. The bubbles and waste gas generated during the fermentation process also need to be discharged in time, which can easily lead to different fermentation effects of the bottom corn slurry and the surface corn slurry, which affects the quality of the corn slurry.
