Abstract:
1. 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 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, and a second vibrator configured to generate second vibrations in the elongate element and a second measuring device to convert second vibrations having passed through the elongate element into second measurement signals, wherein the control device is configured to process the second measurement signals into a quantity that is proportional to the sound velocity in the elongate element, wherein the elongate element is a wire-shaped element and is strung from the first side to a second side of the measuring chamber, wherein the control device is configured to determine a temperature of the milk from the quantity that is proportional to the sound velocity in the elongate element, wherein the control device is configured to convert the quantity that is proportional to the sound velocity in the milk at said determined temperature into a quantity that is proportional to a sound velocity in the milk at a standard temperature, and wherein the control device is configured to determine the milk property from said quantity that is proportional to the sound velocity in the milk.
