AI Technical Summary
Existing fermenters use water cooling during the cooling process, which increases water consumption and raises the cost of microbial fermentation.
Air cooling is used instead of water cooling to prepare compressed air. The compressed air is introduced into the fermentation body through an airlift unit to ensure uniform oxygen distribution. The addition of a ring pipe increases the dissolved oxygen rate. The heated air is reused to dry the fermentation residue, reducing thermal pollution and steam costs.
This has resulted in faster fermentation, increased dissolved oxygen levels, reduced circulating water and steam costs, reduced thermal pollution, and lower production costs.
