Problems solved by technology
[0004] The existing resistive grain moisture measuring device and method use the voltage method to measure the grain resistance, but because the grain resistance is very large, especially when the grain moisture content is low, the measurement signal is weak, the signal-to-noise ratio is low, and it is not conducive to signal transmission, and The influence of the grain's environment on the moisture content of the grain is not taken into account, which will lead to untrue and inaccurate measurement results
[0005] It can be seen that the existing online resistive grain moisture measuring device cannot accurately obtain the moisture content of the grain

The invention discloses an on-line water analysis instrument. The on-line water analysis instrument comprises a cereal drying module, a sampling module, a water collection module, a temperature collection module, a motor control module and a main control module, wherein the cereal drying module is used for heating and drying cereal; the sampling module is used for sampling to-be-detected cereal from the cereal drying module by a motor to obtain sampled cereal; the water collection module is used for collecting the water value of the sampled cereal; the temperature collection module is used for collecting the temperature value of the environment of the sampled cereal; the motor control module is used for controlling operation of the motor and sampling the value of current passing through the motor; the main control module is used for fusing the water value, the temperature value and the current value and obtaining the target water content of the to-be-detected cereal. By application of the technical scheme provided by the embodiment of the invention, the target water content of the to-be-detected cereal can be further increased.
Description
technical field [0001] The invention relates to the technical field of grain moisture detection, in particular to an online moisture analyzer. Background technique [0002] Grain moisture content is the ratio of moisture contained in a specific grain to its weight, and is an important factor affecting grain quality. In practical applications, the moisture content of grain can determine the safety of grain storage, and it also needs to be used in the process of grain processing and distribution. For example, drying is required in the grain processing process. Drying is to achieve the purpose of reducing the moisture content in the grain. Usually, the same hot air or direct heating of the grain is used to reduce the moisture content of the grain. However, to what extent can the drying be stopped? Determined from the moisture content of the grain obtained. Thereby, in the processing process to grain, can not influence grain nutrient composition and quality. [0003] The exis...
