应用板框压滤机去除白酱油中细菌的工艺研究

Study on filtration sterilization of pale wheat soy sauce by frame filter

应用板框压滤机和硅藻土助滤剂对白酱油进行过滤除菌试验 ,结果表明 ,过滤后酱油体态澄清 ,理化指标无明显变化 ,细菌菌落总数小于 1.0× 10 4 cfu/mL ;该工艺还有助于节能降耗 ,提高生产效率。

The experimentation of filtration sterilization of pale wheat soy sauce by plate-and-frametype filter press and filtration mediun(diatomaceous silica)shows that it can remove the mycelidium in the liquid effectively.The processed products have no suspension colloid and transparent in it and they undergo no marked physical or chemical changes.Bacteria colony<1.0×10~4(cfu/mL).The production cycle is also cut down,moreover,it indicates,this process is energy-saving and causes little spoilage of the products.
