Restrict the distance between the ice builder and the milk cooling tank.
In order to reduce heat losses, we recommend to properly insulate the pipes for icewater circulation (e.g.
15 mm Armaflex)
Pre-cooling
Pre-cooling is used to cool down the milk by means of spring water or ice water before the milk enters the
milk cooling tank.
Installation
Depending on the volume of milk one or more pre coolers can be installed.
One pre-cooler can be used to pre cool 1000 liter of milk/hr. To further cool down the milk a second pre-
cooler can be used (see 2 pre coolers (milk inlet serial)). For more than 1000 liter milk a second pre-cooler
should be installed in parallel (see 2 pre coolers (milk inlet parallel)).
The volume of a pre-cooler is 7.6 liter. For good results the milk should enter in batches of 7.6 liter. Water
supply must at least continue for 40 seconds after the milk pump has stopped. Water flow must be equal or
bigger than the milk flow.
It is strongly recommended, when the milk line is cleaned with hot water, a pressure relieve valve
(max. 5 bars) should be fitted at the water outlet side as close as possible to the tubular cooler.
