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 – anyrequiredholding tube outlet temperature isset 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 locations (nine available) Maximum process temperature 85°C TECHNICAL SPECIFICATIONS Optional 15-second holding tube included in supply
