1. Application of new fermentation tank

The new fermenter is adopted to increase the volume of fermenter, optimize the stirring form and cooling method, improve the fermentation yield and reduce the power consumption.

2. Total continuous elimination process was applied in fermentation

The sterilization of fermenter adopts the technology of one-key complete connection, which can reduce the destruction of nutrients in the culture medium, reduce the rate of bacteria infection, and save steam consumption.

3. Apply continuous flyover equipment

The traditional fixed bed is replaced by continuous ion exchange to reduce the consumption of raw materials.

4. Optimize the release process

The optimization method is adopted to ensure that the material moves up gradually in the laminar flow in the new release and maintenance column, so as to ensure that the material and liquid at each place can be maintained for a long time under stable high temperature and effectively ensure the release effect.
