Pasteurisation Systems
Pasteurisation of Juices Containing Pulp and Fibre
The Challenge
Process juices of all kinds, with and without pulp and fibre require a long shelf life and therefore a suitable process treatment. The aim is to guarantee a stable product by means of economic processing.
The Solution
Thermal treatment with pasteurising plants (short time heating plant "STHT") in which the product is heated for a short time only, thus protecting it from long term deterioration without having an adverse effect on the quality in terms of taste, colour, etc. The types of products to be heated, the way of filling and the degree of automation have an influence on the design of such plants.
Brief Description of STHT Plants
The balance tank of these plants may be designed as an open or closed tank. The product heater of the plants is equipped with a secondary hot water circuit having the minimum ΔT between hot water and product. The heat treatment system to be used first of all depends on the properties of the product to be treated. These properties are also deciding factors as to whether the product needs to be deaerated
