SPECIFICATION

Introduction: The process involves heating the process liquid (milk) to a minimum temperature of 72°C, holding this temperature for 15 seconds and cooling to a storage temperature as quickly as possible. The three-stage plate heat exchanger of this achieves these parameters by heating the process liquid with hot water prior to its entry into the holding tube and then by cooling with cold water to storage temperature.

Specifications: A benchtop miniature high temperature, short time (HTST) system for the demonstration of the industrial pasteurization process.Includes a transparent feed tank, a feed pump, a three-stage heat exchanger, a holding tube, a divert system and a hot water circulator.The feed pump is a peristaltic pump with a variable-speed control.The heat exchanger is fully representative of large-scale industrial units.It uses stainless steel heat transfer plates.It can be dismantled for examination and cleaning.It comprises three stages, a final heating stage, a regeneration stage and a cooling stage.Holding time is 15s at 10 l/hr. in a stainless-steel holding tube.Process temperature is measured and controlled.Hot water is circulated around the heating stage of the heat exchanger in a closed-loop system.APID controller is used to adjust the electric water heater, keeping the product process temperature at the requested value.
