PIGNAT Manual Pasteurisation 100 L/H – UPA2000



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.
