Introduce
It consists of air filter , heater ,fluidized-bed main machine, feeder , cyclone separator , cloth bag duster (Optional) ,high-pressure centrifuge fan and air pipe ,control chest. 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, 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 (sending air fan) and belt conveyor for selection. 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. The heating way have different kinds to choice such as steam, electricity or hot air furnace can be used (it can be supplied as client request ).

Principle
The clean and hot air enters into fluid bed through distributor of valve plate. The wet material from the feeder is formed in the fluid state by hot air. Because the hot air contact with the material widely and strengthen the process of heat transferring , it can dry the product within a very short time .
If using continuous type, the material enters from the front of bed, fluidized in bed for several minutes, and discharged from the back of the bed . The machine works under the state of the negative pressure.

Features
1.Automatic production can be realized. It is continuous drying equipment.
2.It is quick in drying speed ,Low in drying temperature ,
3.It have highly polished inner and outer surfaces of the machine, no dead comer, easy to clear, no cross contamination. Confining to the requirement of GMP.
4.It have high collecting rate, high efficiency, fast drying, energy saving.
5.It have not stick onto the wall.
6.Smooth running, reliable performance, easy operation.
7.When oil is used to heat, use automatic constant temperature control. Its temperature of operation can be adjusted form 50-160ºC.
8. Machine materials : AISISUS304 , AISISUS316L, and other material .
9. The feeding system for this machine can be by manual or screw feeder, because the machine is negative pressure drying process, and the feeding materials also can use negative pressure to suck the raw materials into dryer.
10. For the electrical component, we mainly use international brand such as ABB ,Siemens or Schneider.
11. Control system has more choices, such as push button , HMI+PLC and so on.

Application
The dryer is also called fluidization bed dryer. The fluidizing dryer has widely applied in the fields of pharmaceutics, chemicals, foodstuff, processing grain etc. For example, the dehumidification and drying of powder and granular materials such as bulk pharmaceuticals, granular patent medicines, preparations, feed, plastic resin etc. The granular diameter shall be within the range from 0.1 to 6mm and the best from 0.5 to 3mm.
The main technical parameter datum of fluidizing dryer is for reference. Hywell also produce and design product as per customers' requirement.


Optional Choices
1. For the main electrical components , Hywell have international brand choices such as ABB , Siemens or Schneider or others.
2. For the material for the machine , Hywell have choices on AISISUS304 , AISISUS316L,carbon steel and so on .
3. For the control system , Hywell have choices on push button, PLC+HMI and so on .
4. For the heating system for the machine , it is very flexible. Hywell can configure it based on the customer site conditions ,such as steam ,electricity.
5. If without heating system , Hywell can as a cooler to make particle with cooling air.
