Abstract

Abstract

As an instrument to measure grain moisture rapidly, capacitive grain moisture tester is widely used in grain trade settlement, and it is one of the measuring instruments under compulsory management of the state. The measurement accuracy of paddy moisture content based on the principle of capacitive method is affected by many factors. In this paper, the influence factors of paddy varieties are studied and analyzed. The moisture content of 7 different varieties of paddy was measured by 3 capacitive grain moisture testers at two moisture points of about 11.5% and 16.5% respectively. The results show that the paddy varieties have significant influence on the measurement accuracy of the capacitive grain moisture tester, and it is not advisable to use the same moisture tester to measure the water content of different varieties of paddy.
