The milk transport vehicles are equipped with RFID tags. Now every transport step can be tracked: from the laboratory test to quality inspection to the pumps moving milk from the vehicle tank to the storage containers to cleaning of the vehicle tank. This optimizes transport and ensures reliability. For example, since the data is transmitted directly, the time until the laboratory confirms the inspection is shortened. Information from the laboratory about the milk quality, transport time for the milk and the tank cleaning process can be retrieved at any time.
