In the determination of dairy content, a milk freezing point meter is required in order to quickly determine the change in the freezing point of a milk sample. The milk freezing point meter can quickly and accurately determine the freezing point in milk, and the time-fixed measurement, milk performance study, etc. can be suited, and the corresponding parameters can be freely programmed and stored to fit and meet the standards of all countries. So how does a milk freezing point meter work? Let's take a look with Haiyi Technology!
How does a milk freezing point meter work?
The milk freezing point meter is used to accurately detect the addition of water in milk, because the milk dissolves various components such as fat and protein, so the freezing point is lower than water, and the average freezing point of normal milk is -0530 degrees Celsius, and the freezing point of water is 0 degrees Celsius, if water is added to milk, the freezing point of the whole sample will rise, under normal circumstances, 1% of water will be added, and the freezing point of the mixed sample will increase by about 00053 degrees Celsius, when mixed with 100% water, 0530 degrees Celsius, at this time, the freezing point temperature displayed by the instrument is 0 degrees Celsius, and the display is 100% mixed with water.
Calibration instruments, in which the readings are adjusted with two standard solutions until the correct reading is given, and then the milk sample is determined using the same procedure. The probe measures the freezing point temperature of the mixed sample, and uses the internal calculation formula of the instrument to obtain the percentage of water in the milk sample. In this case, the resulting platform is the freezing point of milk.
This method is suitable for the determination of the freezing point of fresh milk rowmilk, pasteurized milk, UHT-treated or sterilized whole milk, partially skimmed milk and skim milk. Determining the freezing point of milk can be used to estimate the amount of foreign water in it.
The above about how the milk freezing point meter works is shared here, the milk freezing point meter uses the freezing point of the liquid to be related to the molar concentration of the solute contained, the higher the total molar concentration, the lower the freezing point. Therefore, by checking the freezing point of milk, the purity of milk can be calculated.
