Background

In production workshops of food, medicine, chemical industry and other industries, the operation of measuring and analyzing the moisture of materials is very common, so that it is necessary to accurately and quickly measure the moisture content of a sample. The common moisture meter adopts a drying weighing method, namely, the weight difference of the materials before and after drying is respectively measured and calculated and then divided by the weight of the materials before drying, and the obtained value is the moisture content of the materials.

The moisture content of grain is an important index for evaluating the quality of grain, so the moisture detection of grain has very important significance for the purchasing, transportation, storage and processing trades of grain. The excessive water content can promote the vigorous activity of the food life, easily cause the food to generate heat, mildew, insects and other biochemical changes, and influence the yield of the finished product food. And if the water content of the grain is too low, the weight of the grain is reduced, the quality of the grain is influenced, and the final total selling price of the grain is reduced.
