FT43 Laboratory Pasteuriser - issue 8

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.

Description

Plate heat exchanger - heating, economising and cooling sections

enlarge

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

This allows 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 1 litre can be processed making the unit ideal for preparing product for kitchen trials and taste panel tests.
