1. Different types of grains and rice should be dried in different ways. When the rice is overdue and has not been harvested, there have been popping or explosive waist varieties in the field, a large amount of cold-damaged rice, broken rice, and unrefined rice are mixed in the rice, and the drying speed should be set to "slower". "Slow" or low temperature range, 3-4°C lower than the control temperature. For immature rice with a lot of green grains, use a grain dryer to increase the stop moisture setting value by 5-6%.
2. Frequently use drying for cleaning and maintenance when idle. Clean up in time, clean up the remaining grains, close the inlet and outlet, etc., which is beneficial to the life of the machine and improves the efficiency of the drying operation.
3. The amount of grains loaded should meet the requirements, not too much or too little. Too much loading will easily cause blockage; too little loading will not only reduce the operating efficiency, but also affect the drying quality. When the full amount is reached, there is still a small amount of rice that can not be added, it can be fed within 1 hour after the start of drying, and the feeding within 1 hour will not cause uneven drying of the grain dryer.
4. When drying rice and wheat with extremely high moisture content, in order to prevent bridging, after the material is fed to the first window, it should be cycle-dried immediately, that is, dry while feeding. Otherwise, there will be many maladies that affect the germination rate, easy peeling, longer drying time, fuel consumption, and unsatisfactory color after drying.
5. The impurity content of grains should not be too high. For example, wet grains and wheat mixed with a large amount of rice straw, wheat straw and other sundries will affect the flow of grains, make some grains unable to get a good circulation, cause uneven drying, and even ferment; at the same time, it will increase power consumption, oil consumption, and reduce efficiency. Therefore, it is necessary to roughly select the grain dryer before drying.
