Description

This self-contained laboratory unit is suitable for HTST

(high temperature, short time) pasteurisation of up to 20 litres/hour of a wide variety of low-viscosity liquid foods. Products that may be pasteurised include raw milk, nectars, fruit juices, skimmed milk,

ice-cream mix, soft drinks, pharmaceuticals and margarine emulsion.

A CIP (clean-in-place) facility is incorporated which allows disinfection, pre-rinsing, detergent washing and final rinsing. The ability to vary process conditions has been built into the unit in the form of the following features:

• Variable speed, peristaltic, hygienic feed pump allowing flow rate variations
• Plate-type stainless steel heat exchanger – the cooling, regenerating and heating sections, mounted on a common frame work, are easily dismantled to allow re-configuration and inspection of the heat transfer surfaces
• Electrically heated hot water circulating system for both pasteurisation and CIP cycles – any required holding tube outlet temperature is set on the indicating microprocessor-based power output controller of the water heater
• Stainless steel holding tube, allowing holding times between five seconds and two minutes
• Flow rates of feed pump, cooling water and hot water are monitored accurately
• Temperatures in the system are monitored with thermocouple sensors at each of six chosen locationss (nine available)
• Maximum process temperature  85°C
