Fermenter cooling method is cooling dribbling with standard parameters, layout and control mode in domestic. Zunhuang companies design and manufacture cooling dribbling according to 0.4-0.5 meters per cubic meter cooling area. And the fermentation tank adopt two-stage cooling refrigerant control mode at the end of the cone and the tank level 10--15㎝ down. So such design and cooling method to control the flow of the cooling liquid state in fermentation tank by the size of the two-stage cooling refrigerant flow. It will improve heat transfer efficiency and cooling rate, faster cooling, and reduce cooling costs and high economic efficiency equipment commercial operation.

    The cooling jackets of fermenting tanks adopts dimple plate, arch channel and fluting channels etc. to exchange heat in abroad. There are many pipelines between the fermenting tanks such as washing pipelines, material pipelines, cooling medium circumfluence pipelines and CO2 pipelines. With the help of PLC auto-control system, the equipment can reach to automatic and semi-automatic system control. This guarantees the accrancy of the process parameters and experimental result.
