Method and device for leading media through a treatment system for a liquid product

摘要

A method and a device for leading media in a thermal treatment system for a liquid product where, determining the led-in volume of the expelling medium while a medium is being expelled from the treatment system and by setting the determined volume of the expelling medium in a ratio to a nominal capacity of the treatment system, the shutting off of a product pipe on the outlet side following a medium change on the inlet side can be accomplished independent in time of the performance of the medium change on the inlet side. This reduces product losses and permits the treatment of residual amounts remaining in the treatment system.

主权项

1. Method of leading media through a thermal treatment system for a liquid product (P), comprising:
a) expelling a first aqueous medium from the treatment system through a product pipe on the outlet side with a second aqueous medium, wherein a medium boundary between the first aqueous medium and the second aqueous medium is generated and the second aqueous medium pushes the medium boundary and the first aqueous medium downstream of the medium boundary through the treatment system, and wherein the volume of the second aqueous medium led into the treatment system in the process is determined; b) shutting off the product pipe on the outlet side, so that the second aqueous medium cannot flow into the product pipe, wherein a trigger (TS2) for shutting off the product pipe on the outlet side is calculated on the basis of the volume determined in step a) and a nominal capacity (VB) of the treatment system; and the first aqueous medium is the product (P) and the second aqueous medium is water (W).
