Boiling dryer, also known as fluid bed, after 20 years of use, improvement, present in the pharmaceutical, chemical, food, food processing, etc., more and more reflect the important role, which consists of air filter, fluidized bed host, medium rare cyclone device, bag filter, high pressure centrifugal fan, console composition. Because the different nature of the dry material, with dust may need to make time, which can select the cyclone, bag filter, also choose one of them usually come on the proportion of larger medium rare materials, simply select the whirlwind device, the proportion of lighter materials to be supporting the bag filter, and equipped with pneumatic feeders to choose from, there is continuous production of the device and the gap two. 
 Principle: clean distribution of hot air through the valve plate body into the bed from the feeder into the formation of the residual material is boiling hot, as hot air extensive contact with the material, enhanced heat and mass transfer process, so within a short time to dry. If a continuous type, the material from the bed into a body, after tens of seconds to several minutes, boiling dry, automatically from the other side of the body out of bed. 
 The equipment is generally the compressed air operations. 
 Application: medicines, chemical raw materials, food, grain processing, feed drying effect, such as pharmaceutical raw materials, pressed particles, granules Chinese medicines, health food, beverage powder, have no germ, feed, plastic resin, granular powder, citric acid and other dehumidification drying of materials for material particles by generally 0.1-6mm, the best grain through the 0.5-3mm.
