Flash dryer is one of the fastest growing and most widely used models. The equipment has a high technical content and is suitable for drying paste, granular, filter cake and slurry materials. Flash dryer has the advantages of high thermal efficiency, short drying time and good energy saving effect. Due to the fast drying speed and short heating time of the material, it is not easy to destroy the components of the dried material, which is particularly beneficial for drying heat-sensitive materials; the drying process is fully enclosed, no impurities are mixed in, the finished product quality is high, and the operating environment is good. At present, flash dryers have been designed into a variety of models according to different materials, and have formed a series of products. The application range in chemical, pharmaceutical, light industry, food, mining and other industries is becoming more and more extensive.

  How to operate the flash dryer correctly?

  1. Install the hot air furnace or other heat source, dust collector, induced draft fan, blower and other supporting equipment. Check the fan to see if the blades are turning correctly. Check the air volume regulating valve and feeding regulating plate to see if they are adjustable and adjust them to the best position according to the design before manufacturing.

  2. After all the checks are correct, ignite the hot air furnace and start the smoke exhaust fan. Later, turn on the fan and motor to put the flash dryer in operation.

  3. Check the instrument panel and wait for the wind temperature to reach the requirement before feeding the material. Note that the feeding speed should be appropriate and should be adapted to the output. During the test, the outlet wind temperature of the general drying host should be controlled at 80℃-120℃. If the temperature is too high or too low, adjust the feeding amount. Also observe whether the main motor is rotating. If it stops, it means that there is too much material in the machine. At this time, the machine should be stopped and cleared in time.

  4. In order to facilitate the calculation of output, the general test time is 1-2 hours. After the test, measure the moisture content of the material. If it does not meet the requirements, adjust the dryer, increase the hot air volume or adjust the speed of the feeder to increase the inlet air temperature.

  5. Finally, after the feeding experiment is over, the temperature should be lowered first. After the hot air furnace temperature drops to the specified value, turn off the host and power supply.
