The pasteurised batch is very uselfull to process fluids with very high viscosity and low conductivity like custard and other viscosity creams.
This configuration permits to avoid the huge pressure drops and to control process of pasteurization with more flexibility.
They can provide a continuous flow of product in inlet and in outlet, managing easily the holding time of the pasteurization.
This flexibility gives the possibility to process a lot of different products and to achieve the best quality of them.
Pasteurizer Batch can be equipped with multiple tanks which work in parallel to provide continuous flow.
The number of tanks needed depends on time required to achieve the pasteurization temperature and on the physical properties of the fluid. Small tanks require shorter heating time.
The heating and the cooling are provided to the product through a jacket around the pasteurization tank and the product is mixed continuously by stirrer inside it.
There is a relation between the volume of tanks and the flow rate provided and it is reported in the follow table.
The minimum number of tank is 2. For special requirements is possible to provide higher flow rate with small tanks.
|Volume of each Tank [L]||Flow rate [L/h]|
