Grain Moisture Testing Method
In the past 20 years, the detection technology of grain moisture has developed rapidly, and detection methods and ideas have emerged in an endless stream. The main grain moisture detection methods can be seen in the table below.
Category Detection method
Category Detection method
Direct method Drying method - reduced pressure method
Direct method Drying method-electric oven method
Direct method Drying method-Microwave heating method
Direct method Drying method-infrared heating method
Direct method Chemical method - Karl Fischer method
Direct method Chemical method-distillation method
Indirect method Electrometric method - conductometric method
Direct method Chemical method - Calcium carbide method
Indirect method Infrared ray method
Indirect method Electrical measurement method-capacitance method
Indirect method Neutron method
Indirect method Microwave method
Indirect method Chromatography
Indirect method NMR method
The direct method is to directly remove the moisture in the grain by drying or chemical methods, and detect the absolute moisture content of the sample. Such methods have high detection accuracy, but are time-consuming and not suitable for online detection.
