Introduction： 
Boiling dryers, also known as fluidized bed. China started from 1963. 20 years, constantly improving, and currently in the pharmaceutical, chemical, food, food processing, more and more reflects its important role. It consists of air filter, heater, fluidized bed host, feeder, cyclone, bag filter, high pressure centrifugal fan, console component. Result of the dry materials are different in nature, matching dust removal device, according to need and can also select the cyclone separator, bag filter, also choose one of them. In general, a larger proportion of the material simply select the cyclone. Lighter weight materials required to complete bag filter, and equipped with pneumatic feed device available. 

Drying Principles： 
After boiling dryer is the use of clean filtered air, through convection heat exchanger, the air temperature rises to a certain temperature into the host points hairdryer, assigned by the valve plate into the boiling device, the wet material from the feeder into the dryer . As the wind effect, the material boiling in the formation of the dryer, hot air extensive contacts with the materials, enhanced heat and mass transfer process in a relatively short time to promote separation of materials in the water evaporation, the devices were generally negative pressure operation. 

Heating method： 
Steam, electricity, hot air furnace can be equipped with. (Can be user request) 

Installation Instructions： 
1, boiling dryer is the key in the installation of all joints must seal, fill the film apart, in order to maintain not leak. If the leak seriously affected boiling effect. 
2, in order to avoid the fan noise, users can mute the fan on the indoor (user self). 
3, installation, cyclone separator, bag filter, fan mounting position variable according to plant location. 

Applications： 
Apply to pharmaceutical drugs, industrial chemicals, food, grain processing, feed the drying operation. Such as: API, pressed particle, granule of Chinese medicine, food and beverage powder, corn germ, feed, plastic resin, citric acid and other powder, granular materials drying dehumidification. For particle size is generally 0.1-6mm, the best size for the 0.5-3mm.
