Abstract

The invention relates to a buoyancy method for rapidly measuring grain moisture and a tester thereof. The measuring method is realized by five steps of dish box liquid injection and suppressing tare weighing, sample preparation, sample weighing, liquid injection and suppressing gross weight weighing and result calculation. The tester comprises an electronic balance, a liquid injection and suppressing device, a data processing display device, a water groove and a dish box. By adopting the grain moisture measuring method and the special tester thereof, the invention utilizes the principle of Archimedes buoyancy law, overcomes the disadvantages of long operation time of a drying method, untimely guidance and slightly great error of other rapid moisture testers, has both the accuracy of the drying method and the characteristic of rapid measurement of various moisture testers, has wide moisture measuring range and multiple measuring varieties, is not influenced by factors such as grains, temperature, and the like, and is widely suitable for grain storage business and the field of grain processing.

Description

technical field [0001] The invention relates to a method for measuring grain moisture, in particular to a method for quickly measuring grain moisture by adopting a buoyancy method, and also relates to a special grain moisture measuring instrument using the method. Background technique [0002] As an important quality index of grain, moisture content directly affects every link of grain purchase, sales, transportation, storage, and processing. Measuring grain moisture is of great significance to the grain sector. How to quickly, accurately and conveniently measure the moisture content of grain is a worldwide problem. Now the United States, Japan, France, Britain, Sweden and many other countries are actively discussing it. Although many methods are used, there are many deficiencies, such as: China's national standard method (drying method), although the detection accuracy is high, is time-consuming, energy-consuming, and inefficient, and cannot achieve fast online detection; a...
