How did the ancients store rice in the rainy season?

In rainy season, rice is preserved as follows:

1, when drying rice and wheat with extremely high moisture content, in order to prevent bridging, after feeding into the 1 window, it should be dried circularly immediately, that is, while feeding. Otherwise, there are many disadvantages such as affecting germination rate, easy peeling, long drying time, oil consumption, unsatisfactory color after drying and so on.

2. Different drying methods should be adopted for paddy with different properties. When the rice has not been harvested after the expiration date, and the field has exploded, and there are a lot of cold-damaged rice, broken rice and chaff mixed in the rice, the drying speed should be set to "slow", "slow" or low temperature, which is 3-4℃ lower than the control temperature. For immature rice with more green grains, the set value of stopping water is increased by 5-6%.

3, the grain impurity rate should not be too large. For example, wet grain and wheat are mixed with a lot of straws, wheat stalks and other sundries, which will affect the grain flow, make some grains not circulate well, and cause uneven drying and even fermentation; At the same time, it also increases power consumption and oil consumption and reduces efficiency. Therefore, it is necessary to make a rough selection before entering the dryer.

4. Always clean and maintain when it is dry and idle. Clean up in time, clean up surplus grain, close import and export, etc. Is beneficial to the mechanical life and improves the drying efficiency.

5, grain loading should meet the requirements, not too much, not too little. Too much loading is easy to cause blockage; Too little loading not only reduces the working efficiency, but also affects the drying quality. When a small amount of rice can't be added when it reaches full capacity, it can be replenished within 1 hour after drying, and the replenishment within 1 hour will not cause uneven drying.
