Experimental study of the difference between the inter-plate holding section and the zig-zag type holding tube in a plate pasteurizer

Abstract

Plate heat exchangers are widely used in heat treatment of milk and milk products. The main working part of the plate pasteurizer is a heat exchange unit consisting of three parts (cooling, heating, recuperation). Plate pasteurizer, as we mentioned above, heats raw milk and is used to eliminate various bacteria and viruses that are harmful to the human body in raw milk. The holding section of the pasteurizer plays an important role in decontamination. In some pasteurizers, the holding section is located between the plates. But in modern pasteurizers, retention is carried out through an additional zig-zag tube installed on the outside. The article analyses the difference between the inter-plate holding section and the zigzag type external holding tube in the pasteurization of milk.
