The flash dryer equipment is not uniform during the atomization process, which is usually caused by clogged nozzles or wear in some areas. In order to ensure the normal operation of the equipment, the sprinkler head should be cleaned and replaced regularly. Before starting the flash dryer, make sure you have all the items you need, clean the refrigeration purified water bucket and feed bucket, and check the feed pump and feed pipe for leaks.
Flash dryers are widely used in chemical plants and food enterprises to convert aqueous solutions and mixtures into powdered products. Due to its excellent drying effect and small impact on the environment, it is highly regarded in the industry. However, there may be some problems during use, which will affect the drying effect of the raw materials. Here, we will briefly analyze the common problems in the application process of flash dryers.
The temperature of the inlet and exhaust air system is too high or too low, which is often related to pressure issues. During operation, adjust the pressure of the air inlet and exhaust system of the device appropriately. Problems with impurities or color deviations in the dried finished product are usually caused by incomplete air purification, or too high or too low a temperature during heat treatment.
There are many reasons for the high water content of the dried finished product and the poor drying effect, such as raw materials, drying temperature, inlet and exhaust air volume, heating area, etc. Therefore, it is important to find out the cause before making adjustments.
Finally, check the disc valves on the lines connecting the dehumidifier to the asphalt mixture drum and make sure they are all open. In order to ensure that the fine particles are in full contact with the hot air stream, sufficient heat exchange is carried out, so as to achieve the purpose of the flash dryer.
