WERKWIJZE EN INRICHTING VOOR HET STERILISEREN VAN EEN INRICHTING VOOR THERMISCHE BEHANDELING VAN VLOEIBARE PRODUKTEN.

摘要

A method of sterilizing apparatus for the heat treatment of liquid products comprises displacing air from the apparatus by steam, circulating hot water through the apparatus so that hot water is sprayed into a vessel and thereby heated by the steam until the steam pressure in the vessel required to reach and maintain the sterilization temperature in the coldest part of the vessel is reached and maintaining this pressure until the sterilization temperature has been maintained for a predetermined sterilization period in the coldest part of the apparatus, subsequently discontinuing the steam supply and cooling the water by a heat exchanger while supplying sterile air which maintains an excess pressure in the apparatus during subsequent discharge of the water. The apparatus is modified to allow this method to be performed.
