Fluid bed dryer is a new technology developed on the basis of static fluidized bed. Mechanical vibration is added on the static fluidized bed. The material has been feed into the machine from the front of machine, Fresh air through filtering and heating is sent to the bottom of fluidized-bed by fan and contacts with solid raw material on vibration bed plate. under the dual function of the vibration and air flow, the materials move along the fluidized bed as throwing forward continuously. In this way 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 ,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 ).
1. The state of fluidization is uniform, with no dead angle and blown through phenomenon.
2. It is good in regulation and wide in suitability. The moving speed and the bed depth of the material in the dryer can achieve stepless adjustment by the changes of the amplitude.
3.It makes small damage to the surface of the material, can be used for the drying of the fragile materials and will not affect the work results if the particles are irregular.
4.Materials have been heated evenly, full exchanged the heat. It is a process of large intensity of drying.
7. Machine materials : AISISUS304 , AISISUS316L, and other material .
8. The feeding system for this machine can be by manual or screw feeder or conveyor belt.
9. For the electrical component, it can use international brand such as ABB ,Siemens or Schneider (optional).
10. Smooth running, reliable performance, easy operation.
11. Highly polished inner and outer surfaces of the machine, no dead comer, easy to clear, no cross contamination.
12. Control system has more choices, such as push button , HMI+PLC and so on.
13. The vibration is created by motor. It is stable in operation and convenient in maintenance, low noise with long life span.
14. The dryer adopt closed operation, protect raw material from cross-contamination, it is in continuous production
Vibrating fluid bed dryer is widely used in light industry, chemical industry, foodstuff, agricultural products, powder, granule, and small block material in pharmaceutical industry. Material examples are as following: refined salt, citric acid, oxalate, potassium permanganate, sesame, pentaerythritol, feed, hypha protein, sodium sulfate, plastic archon, catalyst, stripping and slicing potato, baking soda, detergent, quartz sand, soybean billet, ban pulp, metal powder, boric acid, sodium borate, activated clay, compound fertilizer.
if using cooling air , the machine will be the best cooler for decreasing the temperature of the dried product.
