Plate Heat Exchangers are the units where the Ice Cream Mix is cooled down to the Ageing Temperature (8-10 0C) after being pasteurised by Sp Makina Mix Pasteurisation Tank. Further cooling down to 4-6 0C is performed inside the Ageing Tank.
The cooling down should be applied very quickly after the milk reaches the desired pasteurisation temperature for preventing any negative result of over-heating and also the löse of time. Hence the capacity of PHE should be selected for cooling the milk in 15 or maximum 30 minutes.
Using Chilled Water for the entire cooling process will result with a high cost. For this reason; Mix Cooling PHEs are designed as 2-Stage.
1st Stage; Cooling Down from Pasteurisation Temperature to Ambiant T (25-30 0C) by mains water
2nd Stage; Cooling Down from Ambient Temperature to Ageing T T (8-10 0C) by Chilled water
