Grain moisture measurement method-grain moisture analyzer measurement method detailed introduction

Grain moisture measurement is a work that needs to be carried out in many fields such as grain storage, purchase and processing. In order to obtain an accurate grain moisture value, people have adopted many methods for testing. According to different measurement principles, grain moisture measurement methods Mainly can be divided into resistance method, resistance method, drying method, capacitance method, infrared method, microwave method, neutron method, high frequency impedance method, nuclear magnetic resonance method, acoustic method, etc. This article mainly introduces the measurement method of grain moisture analyzer.

The measurement method of the grain moisture analyzer is to directly use the instrument for measurement. The instrument measurement has the advantages of high automation, strong operability, fast measurement speed, and wide application fields. The reason why grain moisture analyzers are used to measure grain moisture in many modern fields is mainly because the measurement methods of grain moisture meters have many advantages.

1. Advantages of grain moisture analyzer measuring method:
1. Fast, accurate and convenient;
2. Automatic weighing; automatic temperature compensation; automatic moisture measurement; automatic shutdown;
3. Empty machine to correct moisture; compensation mode; AC and DC dual purpose;
4. Users can calibrate and correct errors by themselves.

2. Principle of measurement method of grain moisture analyzer:
Keep the distance between the Yuantong pole plate and the Yuantong pole plate unchanged, and put the sample between the two poles. The difference in the moisture content of the sample causes the dielectric coefficient between the poles to change, and the capacitance of the flashlight sensor also changes, thereby indirectly measuring the moisture content of the grain. . The instrument has the advantages of fast measurement, no need to crush the sample, and strong portability. At the same time, it is easily affected by the environmental temperature, resulting in poor measurement accuracy and low stability.

The above is about the "grain moisture measurement method-detailed introduction to the measurement method of the grain moisture meter". The grain moisture meter is suitable for the determination of the moisture content of most grains such as rice, soybeans, wheat, rapeseed, corn, barley, indica, rice, etc. After the application, the detection efficiency is greatly improved, manual estimation errors are avoided, and the production, processing and high-level storage of high-quality grain and oil are promoted.
