Description
Study of pasteurization on a unit equipped with a 3 zone industrial heat exchanger: preheating, heating, cooling
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 exchanges heat successively with 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 (optional):
- Thermal balance of the heating zone: product and hot water
- Heat balances on the cooling zone: Product and cold water
Proposed experiments:
- Study various holding time and heating temperature combinations by microbiological testing.
- Calculate the pasteurization value F.
- Clean the unit in place.
- Monitor temperature variations and thermal balance during the various phases of treatment with option O2.
