The inlet product to the buffer storage tank, reaches the solution heating stage through a centrifugal or volumetric pump.
The heating of the solution is obtained in two steps, one thanks to the energy recovery of the heat exchanger and the other with the aid of a hot-water circuit .
Achieving and controlling of the pasteurization temperature occurs with the aid of a hot water circuit which allows a much more responsive and accurate temperature control, avoiding the problems related to the exchanger’s fouling.
The final stabilisation is carried out within the holding stage piping. The solution cool down in two steps, one thanks to the energy recovery of the heat exchanger, and the other with the aid of cold water which controls the filler inlet temperature.
In case of hot filling cooling of the returning product from the filler, takes place in two steps using tower water and cold water in order to achieve the desired recycling temperature, and it could be recovered in a scrap recovery tank.
