Patent ID: 8650938

Claim:
A milk property measuring device, comprising: a measuring chamber configured to house milk; a first vibrator provided at a first side of the measuring chamber, configured to generate first vibrations to set the milk in the measuring chamber into vibration; a first measuring device configured to convert the first vibrations having passed through the milk into first measurement signals; a control device configured to control the first vibrator and to process the first measurement signals into at least a first quantity that is proportional to a sound velocity in the milk further comprising a reference device connected to the control device, wherein the reference device comprises an elongate element provided in the measuring chamber and to be surrounded by the milk filled into the measuring chamber, a second measuring device to convert vibrations having passed through the elongate element into second measurement signals, wherein the vibrations measured by the second measuring device are generated by the first vibrator or are generated by a second vibrator integral with the first vibrator, configured to generate second vibrations, and wherein the control device is configured to process the second measurement signals into a second quantity that is proportional to the sound velocity in the elongate element, and wherein the control device is configured to determine a milk property from the first quantity and the second quantity.
