Embodiment Construction

[0061] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0062] See figure 1 The embodiment of the present invention provides an on-line resistance type grain moisture measurement device, which includes: a grain dryer 1, a sampler 3, and a measuring instrument 5.

[0063] Among them, the elevator 2 is used to transfer the grains from the bottom of the grain dryer 1 to the top, and the grains are scattered freely from the top. The hot air blown from the grain dryer 1 heats and dries the scattered ...

Abstract

The invention provides an online resistance type device and an online resistance type method for measuring water of grain. The online resistance type device comprises a grain dryer, a sampler and a measurement instrument. The invention further provides a method for measuring the water of the grain by using the online resistance type device. By using the method and the device, intelligent automatic operation of the grain dryer can be realized, the influence caused by temperature and impurities is eliminated, and the water of the grain is accurately measured.

Description

Technical field [0001] The invention relates to the technical field of agriculture, in particular to an on-line resistance type grain moisture measurement device and method. Background technique [0002] Grain moisture is an important factor affecting grain quality. The moisture content of grains not only determines the safety of grain storage, but also restricts grain processing and circulation. Excessive moisture in grains can easily cause heat, mildew, and insects. Using a grain dryer to dry grains is currently the most effective way to reduce grain moisture. During the drying process, the moisture of the grain must be measured to avoid the low moisture content of the grain, which will affect the nutrient composition and quality of the grain. [0003] Measurement methods can be divided into manual sampling offline measurement methods and online automatic measurement methods. The online automatic measurement method can automatically sample, measure and display, and has the adv...
