1. The cereal impurity rate should not be too large. Such as wet grain, wheat mixed with a large number of straw, wheat straw and other debris, will affect the flow of grain, so that some grains can not be a good cycle, causing uneven drying, and even fermentation; also increase power consumption, fuel consumption, reduce efficiency. Therefore, it is necessary to rough-select before drying.
2. The amount of grain loaded should meet the requirements. It should not be too much or too little. Excessive loading may cause clogging; loading too little will not only reduce the operational benefits but also affect the drying quality. When it reaches the full quantity, when there is still a small amount of rice that cannot be added, it can be re-injected within one hour after the drying. The feeding does not cause uneven drying within one hour.
3. When drying rice and wheat with extremely high moisture content, in order to prevent bridging, after entering the 1 window, it should be dried immediately after drying. Otherwise there are many ills such as affecting germination rate, easy peeling, longer drying time, fuel consumption, unsatisfactory color after drying, etc.
4. Different types of rice should adopt different drying methods than conventional methods. When the paddy rice has not been harvested after expiry, the drying rate has to be “slower†when there are already popping or explosive varieties in the field, a large number of cold rice, broken rice, mixed cereals in the rice, and dry beer and wheat. "Slow" or low temperature, 3-4°C lower than the control temperature. For unripe, more grainy rice, take a 5-6% increase in the set point for stopping water.
5, often use the drying idle cleaning and maintenance. Clean up in time, clean up residual grains, close the entrance and exit, etc., which will benefit the mechanical life and improve the efficiency of the dryer.
