Make sure your milk is good quality. The centre strains your milk into a dump tank to remove impurities. From the dump tank, the centre pumps the milk through a filter to a cooling tank. The centre cools the milk and stores it in a farm-tank cooler. The cooler has an agitator to speed cooling and prevent a cream layer forming.
Some small centres use a surface cooler.
Warm milk enters and the cool milk in cans is ready for transport. 16 Tanker trucks collect the milk from the centres and send it to the dairy. The centre will keep records and accounts and arrange payment for your milk. If there is no town supply, drill a borehole and use a pump. If a borehole is not possible, use a shallow or rain water attachment.
