Operation
In the table below, you will find a description of the operation of the DIB cooling system:
Stage
Description
1 *
The fresh milk runs through the pre-cooler (1).
2 *
Ice water, coming from the ice builder (4), is pumped in counter flow
through the same pre-cooler by means of the ice water pump (5).
3 *
The ice water in the pre-cooler takes the heat from the milk. This is
how the milk is pre-cooled.
4
The milk now runs into the milk cooling tank (3).
5
Ice water is also being pumped into the heat exchanger (2) of the milk
cooling tank.
6
The ice water in the heat exchanger takes the heat from the milk. The
milk is now being cooled until the temperature setpoint is reached.
7
The warmed up water, coming from the pre-cooler as well as from the
heat exchanger of the milk cooling tank, runs back to the ice builder
(4) for cooling.
8
The cycle is repeated.
* Optional, only when there is a pre-cooler present.
