Fluidizing dryer treated as another type of fluid bed. Through operation and improvement over 30 years/ it has play an active part in the fields of pharmaceutical/ chemical/ foodstuff/ gain and so on industries. It consists of air filter/ fluid bed/ cyclone separator/ dust collector/ high-speed centrifugal fan/ and control cabinet and so on. Because of the difference of property from raw material / it is necessary to equip dust remover in accordance with practical needs. It may select cyclone separator and dust collector both or one of them. In general/ cyclone separator can be selected if the raw material is larger and the dust collector may be selected if the raw material is light. Moreover/ there is pneumatic feeding device for your selection. There are two kinds of operation for this machine/ continuous and intermittent type.
Boiling dryer is also called as fluidized -bed. It consists of air filter, heater, fluidized -bed main machine, feeder, cyclone separator.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 fluidized bed 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.
Steam, electricity or hot air furnace can be used(it can be supplied as request) 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.
The clean and hot air enters into fluid bed through distributor of valve plate. The wet material is fed from the feeder forms the fluid state by hot air. Because of the wide contact between hot air and raw materials/ the time of drying is short. If use continuous type/ the material enters from the front of bed/ fluidized in bed for several minutes/ and float another side of bed. The machine’ works in negative pressure.
This fluidized bed dryer can achieve automation and continuous drying process. It has a high drying speed and a low temperature and the product quality can be ensured, meeting GMP requirements. The heating resource can be steam, electricity or furnace
Drying process of medicines/ chemical raw material/ foodstuff/ grain processing/ feed and so on. For example/ raw medicine/ tablet / Chinese medicine/ foodstuff of health protection/ drinks/ feed/ resin/ citric acid and other powders. The suitable diameter of raw material is normally 0.1-0.6mm. The most applicable diameter of raw material will be 0.5-3mm.
