Background technique

In the food processing industry, the quality of the source of raw materials directly affects the quality of the product. In order to ensure the qualification of the raw materials, the raw materials must be preprocessed. Rice processing is to process rice into edible rice. The rice in the processing factory is from different sources. The rice is purchased locally, so the moisture content of the rice is very different. During the processing of rice, the moisture content of the processed rice needs to be strictly controlled. If the moisture content of the rice is too high, whether it is impurity removal or the following Processes such as rice hulling and polishing are difficult to operate and can easily cause machine blockage. The peeling process of rice hulling will also be difficult to complete. Therefore, the factory must dry rice according to different moisture contents to ensure normal production.

In some existing grain drying devices, when grains are put into the device for drying, they are prone to stacking, resulting in low work efficiency, and the grains are dried unevenly, causing some grains to fail to meet drying standards.
