1. Drying in time Dry rice grains in time after threshing. The water content of rice after threshing is high, and it is prone to sprouting and mildew if it is not timely dried. Bamboo mats or three-segment soils can be used for intermittent drying or drying in the drying field for a few days to reduce the broken rice rate and improve the rate of whole polished rice. Rice water content below 13% can be safely stored. 2. Should not be exposed Rice has poor high temperature resistance and should avoid high temperature exposure. If the sun is exposed, there will be more lumps, and after processing into rice, there will be more broken rice, low rice output rate, poor quality, and not a good price, which will affect farmers' income. Rice should be dominated by drying. If rice is exposed to sunlight, it should be spread thicker, especially when it is sunning on cement, and it must be moved frequently to prevent local rice from being overheated and affect rice quality. 3. The site is clean The airing site should be cleaned to avoid impurities (such as weeds, mud blocks, sand and other debris) mixed. The sun must not be on the ground beside the road or other contaminants (such as asphalt).
