FOOD TECHNOLOGY
FT43 Laboratory Pasteuriser with Temperature Indication

The Armfield FT43 laboratory pasteuriser is a miniature-scale HTST unit, which allows developers to test the effects of heat processing on product quickly and economically.

The HTST pasteurisation process can be undertaken using very small quantities of product in a relatively short time so testing is both quick and economical. Temperatures of up to 90°C can be achieved and holding times varied with throughput using the two holding tubes supplied.

The unit can operate with as little as one and as much as 30 litres of product per hour.

Features

• Miniature plate heat exchanger
• Fully self-contained design with integral hot water system
• Choice of holding tubes
• Variable product temperature and holding time
• Control console incorporating comprehensive instrumentation
• CIP facility

Benefits

> Benchtop operation
> Tests can be carried out quickly and easily
> Simulates the conditions used in a production plant
> Small quantities of liquid product can be processed

Description

Plate heat exchanger - heating, economising and cooling sections

The Armfield Laboratory Pasteuriser has a unique miniature plate heat exchanger with heating, interchanging and cooling sections. Two holding tubes are provided to enable a wide range of holding times to be achieved.

This enables processing conditions identical to those in production equipment to be achieved and the certainty that any organoleptic and physico-chemical changes will be replicated.

Batch sizes as small as one litre can be processed making the unit ideal for preparing product for kitchen trials and taste panel tests.
