Ethanol Production Machine Liquefaction Section High Starch Conversion Rate
Liquefaction process (cassava feedstock)
Slurry in the mixing tank is conveyed to the hydrocyclone desanding machine by the slurry pump, the slurry after desanding is stored in the temporary storage tank and amylase is added into the tank, then the slurry in the temporary storage tank is conveyed to 1 # 2 # spiral plate heat exchanger by slurry pump, and exchange the heat with the liquefied mash from the later liquefaction tank. The slurry enters into the pre liquefaction tank, and is conveyed by liquefied mash pump to the spray liquefier for cooking and liquefying, cooking temperature is 105 ℃, liquefying temperature is 95 ℃, liquefaction time is about 120 minutes.
