Laboratory Pasteuriser

Laboratory Pasteuriser Pasteuriser is an example of the modern high temperature, short time (HTST) pasteurisers used in commercial food production.

It utilises a three stage plate heat exchanger and provides an excellent example of a production line approach to food manufacturing, complete with associated systems and control aspects. A bench top miniature High Temperature Short Time (HTST) system for the demonstration of the industrial pasteurisation 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 15 seconds at 10L/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. A PID controller is used to adjust the electric water heater, keeping the product process temperature at the requested value. Maximum hot water temperature is 85°C. Normal product process temperature is 72°C; this can be varied by the operator. Optional data logger with USB interface is available.
