Problems encountered in drying the grain drying tower
The four common senses of using large-scale grain drying towers: the use of grain drying towers also promotes the current rate of agricultural production and processing, and also brings great convenience to people's production and life. It is also very good. Drying effect, then we will introduce to you the precautions in the use of grain drying tower equipment. 1. Maintenance and maintenance of grain drying tower We still need to clean the burners of the grain drying tower regularly. Check and improve the tightness of the belt's triangular 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 passage openings in the grain drying tower are also closed; if it is not ready for a long time, it is necessary to relax the conveyor belt and the transmission belt. 2. Key points for safe operation of grain drying tower During the operation of the grain drying tower, the site must also be a skilled operator, and there should be no staff 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 are not 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 drying tower is very important. It is an important factor that can affect the use effect. On the basis of selecting high-quality equipment, it is necessary to strictly follow the instructions for use and to make regular equipment. Inspection and maintenance work, found that the problem should be handled in a timely manner to prevent greater damage and extend the life of the equipment. Amber Sterile Vials are produced by aluminum caps, non-latex butyl stoppers and amber SCHOTT Neutral Type I glass vials.
