DEVICE AND METHOD OF PACKING STERILISATION Russian patent published in 2008 - IPC B65B55/10 

FIELD: technological processes.

SUBSTANCE: invention pertains to the device and method of sterilising packaging during production. The device consists of a heating zone, sterilisation zone, blowing zone and apparatus for maintaining higher pressure in the sterilisation zone than in the heating zone and the blowing zone. A gaseous sterilising substance is used to sterilise the packaging. The sterilising substance is kept in the gas state for the whole period of the sterilisation process. The method of sterilising a packaging with an open and a closed end involves passing the packaging through the heating zone first, where it is heated to a temperature above the dew-point temperature of the sterilising substance. Positive pressure is maintained in the sterilisation zone. Any leakage of gas or air between the sterilisation zone and the surrounding heating and blowing zones takes place from the sterilisation zone into the direction of the surrounding zones.

EFFECT: making a device and method of obtaining a more reliable sterilisation process.
