Description

This self-contained laboratory unit is suitable for HTST

(hightemperature,shorttime)pasteurisationofupto20litres/hour ofawidevarietyoflow-viscosityliquidfoods.Productsthatmaybe pasteurisedincluderawmilk,nectars,fruitjuices,skimmedmilk,

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

ACIP(clean-in-place)facilityisincorporatedwhichallowsdisinfection, pre-rinsing, detergent washing and final rinsing. The ability to vary process conditions has been built into the unit in the form of the followingfeatures:
