Method for durability treatment of a pumpable material as well as a device therefor

摘要

The invention relates to a method for durability treatment or sterilisation of a pumpable material by high pressure treatment of the same in a high pressure press for killing and/or inactivating harmful microorganisms and enzymes in the material. In the method, the pumpable material is filled into a flexible bulk container (1) with a larger volume than the end-user or consumer containers in which the material is intended to be packed. Then the bulk container is placed in a high pressure press and subjected to high pressure treatment at a pressure of at least 2000 bar. After completed high pressure treatment, the bulk container is removed from the press. Finally, sterile emptying of the pumpable material from the bulk container is effected by arranging in a sterile manner at least one connecting means (14) on the bulk container which via a tube (17) connects the interior of the bulk container with an emptying system, for the purpose of filling the pumpable material into the end-user or consumer containers or into an intermediate storage tank. The invention also relates to a device for performing sterile emptying in connection with the durability treatment.
