Application of sartorius microwave drying moisture analyzer LMA200PM to quickly and directly analyze the moisture content of pure milk and liquid yogurt

Sartorius microwave drying moisture meter LMA200PM takes the oven drying method as a reference, and quickly heats the sample by absorbing microwave radiation through the sample. This experimental method determines the moisture content of the sample by heating the sample and calculating the weight change of the sample before and after heating. Due to the principle of microwave drying-the microwave radiation at 2.45GHz is only absorbed by the water molecules in the sample, but not by the fat. Therefore, the result of this experiment is basically free of the fat content of milk. Compared with the oven method and infrared drying method, the experimental result is slightly lower and closer to the true value of moisture. Because the weighing system of the moisture meter has an external calibration function, it shows that the measurement result of the moisture meter-moisture content is traceable.
