Pateurization unit

The design of this unit allows a heat treatment to destroy all pathogenic bacteria,

as well as most ordinary germs present in a product.

The system exchangers heats successively the product before sending it to the tube.


Multipurpose pasteurizer

Output cold, warm or hot product according to the use of pasteurized product

Control unit for setting the desired temperature and flow


Effects of heat treatment on the product during the pasteurization

Influence of the holding time and heating temperature on the quality of

the treated product

Determination of the effect of pasteurization on the bacterial flora in the product

upstream and downstream of the pasteurization


Study of heat exchange (option)

Thermal balance of the heating zone: product and hot water

Heat balances on the cooling zone: Product and cold water
