METHOD FOR HEAT-STERILIZATION OF LIQUID STORED IN FLEXIBLE CONTAINER

摘要

PURPOSE:To attempt to prevent a container from breakage caused by pressure increase in the container by providing a liq. level sensor detecting the liq. level in a liq. storing container placed in a sterilization container and performing pressure control in the sterilization container so as to make the liq. level detected by this liq. level sensor const. CONSTITUTION:A liq. storing container 2 with flexibility storing a liq. 1 is placed in a sterilization container 3 and while this sterilization container 3 is closed, temp. in this sterilization container 3 is elevated for example by feeding steam in the sterilization container 3 to perform heat sterilization of the liq. 1 in the above described liq. storing container 2. In addition, in a method for heat sterilization of a liq. stored in a flexible container, a liq. level sensor 4 detecting the liq. level in the liq. storing container 2 stored in the sterilization container 3 is provided and pressure control in the sterilization container 3 can be performed so as to make the liq. level detected by the liq. level sensor 4 const.
