Descriptions

Boiling dryer is also called as fluidized - bed. It consists of air filter, heater, fluidized - bed main machine, feeder, cyclone separator, cloth bag duster , high-pressure centrifuge fan and operation table. Because the properties of raw materials exist difference, when equip the dust removing equipment, it should consider the practical need. It can select cyclone separator and cloth bag duster at the same time or one of them . In general speaking, it needs to select .cyclone separator only for raw material that is large in specific gravity and cloth bag duster for powder and small granule raw materials that is light in specific gravity. Meanwhile there is air feeding device and belt conveyor for selection.

Separated granule solid raw material is fed into fluidized-bed drier through feeder. Fresh air through filtering and heating is sent to the bottom of fluidizedbed by fan and contacts with solid raw material on distributing plate. In this way the fluidized state is formed and the heat exchange between air and solid is carried out. The dried raw material is discharged from outlet and wasted gas is exhausted from the top of fluidized-bed where catches solid powder through cyclone separator, cloth bag duster.

Principle

Working principle can be detailed as:Cleam hot air enters into the bed through valve distribution and enables the wet materials entered from feeder to form fluidized state ,just like boiling water jumps inside the bed,thus it's called fluidized drier,the sufficient contact of hot air with materials realizes the prompt drying process.which takes only a few seconds time to finish the whole fluidization

Working principle

○ It is suitable for drying separated granule such as, raw material of pharmaceutical industry, tablet, tablet of drink of Chinese traditional medicines; plastic resin, citric acid, other powder and granule of chemical industry, powder of drink, corn embryo feed of foodstuff industry and so on. The Max diameter of raw material to be dried will be 6mm and the best diameter will be 0.5～3 mm.

Installation description

○ Fluidized bed ,spiral separator and bag dust filter can be positioned directly on the flat cement floor without anchoing bolt.Fan can be in-door or out door installed with base and anchoring bolt,outlet shall be desighed according to actual conditions.

○ No leakage is allowed to the air route system to avoid influence to the drying result.
