  • Storing Milk The milk is refrigerated at 4 degrees Celsius for 2 days. After the milk has been collected, the storages are cleaned before the farmer milks again.
  • Tankers The milk is collected every 1 or 2 days. The trucks that collect the milk are called tankers, and they are made from special stainless steel to keep the milk cool. The truck drivers are milk graders, who accept good qualities of milk and reject bad qualities of milk. The tanker then transports the milk to the factories for laboratory testing.
