YSJ Serial Spray Type Pasteurization Tunnel

YSJ Series spray type pasteurization and cooling tunnel performed food sterilization on normal pressure, its temperature is controlled 2~3℃lower than water boiling point, the actual temperature is often decided by food sterilizing technical requirement and location(when air pressure lower than boiling point, temperature is low, so maximum sterilizing temperature is low too.)

It adopts sterilization method, the principle is limited in a certain temperature range85℃-90℃,If the temperature is high enough, the bacteria will die. Different bacteria have different optimum growth temperature, heat resistance, and cold capacity.

Applicable product:high temperature instant sterilization of liquid materials such as milk,soy milk , food, fruit juice and so on.
