The use of grain dryers has promoted the speed of current agricultural production and processing, and has also brought great convenience to people's production and life, and also has a very good drying effect. When the grain dryer is used, various failures sometimes occur due to the influence of materials, processes, parts aging and human factors. Sudden failures in the production process are a headache, not only affecting the progress of the work, causing unnecessary financial losses, but also reducing the service life of the grain dryer. Therefore, mastering some methods for analyzing faults and correct solutions to faults are quite necessary for users and friends.
What should I do if the grain dryer encounters problems during drying?
1. Maintenance and maintenance of grain dryer
We still need to clean the burners of the grain dryer regularly. Check and lift the belt tension of the conveyor belt or whether there is any deviation. If necessary, make appropriate adjustments. After the season of operation, it is necessary to thoroughly clean the residual grains and weeds in the machine: remove the exhaust hose and the exhaust hose and put it away. The exposed wires are either removed or placed in the machine to prevent the mouse from biting the wires. Then, all the passages in the grain dryer are also closed; if it is not ready for a long time, it is necessary to relax the conveyor belt and the belt.
2, grain dryer safety operation points
During the operation of the grain dryer, the site must also be a skilled operator, and there should be no idle personnel around. Do not touch the burner with your hands during work. Do not put your hand into the hopper when entering the valley: When troubleshooting, wait for the standby device to stop running. The site of the operation is strictly prohibited from fireworks and equipped with fire-fighting equipment.

3, the degree of drying
Different foods still have different drying requirements for storage. Generally, rice can be dehydrated to 13.5% in glutinous rice and dehydrated to 14.5% in late rice. There is an automatic grain drying tower for the determination of moisture content. The initial reading should also verify that the readings are correct and correct if necessary. When testing moisture, different foods, the knob should be adjusted to the corresponding grain position, so that the readings will not be wrong.
If the measurement is carried out with an artificial moisture meter, it should be tested 3 to 5 times. The shutdown can only be performed when all of the drying requirements are met. Note that in the later stage of drying, as the water content of the grain is reduced, the weight is reduced, and some of the less full grains are discharged by the exhaust fan. Therefore, it is necessary to check the situation of the exhaust in the later stage. Once it is found that more grains are blown out, the damper of the small exhaust fan should be properly closed.
4, a reasonable adjustment of the speed of drying
The air volume is large, the wind temperature is high, the installed grain is small, and the speed of dehydration is fast, but the bursting rate of grain will rise. Therefore, it is still necessary to operate according to the regulations, so that the speed of dehydration is controlled within the design range. The hourly dewatering rate of batch circulating grain drying towers is below 2%. Some models do not exceed 1%. Grain dryer can better ensure the quality of grain. The heating in the grain drying tower is intermittent. In the * rated grain capacity, a cycle time is about 1 hour, of which about 1/4 The time is used to heat up. Another 3/4 of the time is for the unheated slow-drying stage, so that the inner moisture of the grain spreads to the outer layer, reducing the bursting waist. For the same moisture content of the same amount of grain drying, two-stage drying can be used. That is, when dehydrating to 18% moisture content, the operation is stopped for more than 5 hours, and then the moisture which is dried to the warehouse can be continued. It can also be dried at room temperature and then dried in continuous hot air.
The performance and quality of the grain dryer is very important, and it is an important factor affecting the use effect. On the basis of selecting high-quality equipment, it is necessary to strictly follow the instructions for use, and do regular maintenance of the equipment. Work with maintenance, found problems to be dealt with in a timely manner, to prevent greater damage and extend the life of the equipment.
