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