Application
※ Use screw to extrude and vibrate granule and granulate granule with the method of humidity, high speed and mixing.
※ Suitable for drying humidity block or powder raw material in the fields such as pharmaceutical, foodstuff, feed, chemical industries and so on.
※ The raw material is large in granule and small in block and having adhesive property.
※ Suitable for raw materials, its volume will be changed when dry, such as giantarum, polyacrylamide, etc.
Principle
※ When air is purified and heated, it is introduced from the bottom of induced-draft fan and passed through the screen plate of raw material. In working chamber, the state of fluidization is formed through stirring and negative effect. The moisture is evaported and removed rapidly and the raw material is dried quickly.
Feature
※ The structure of fluidization bed is of round so as to avoid dead corner.
※ Inside the hopper there is a stirrer in order to avoid agglomeration of raw material and forming canal of flow.
※ The granule is discharged throgh the method of turning over. In this way it is very convenient and full. The discharging system can be designed as request too.
※ It is operated at the conditions of negative pressure and seal. The air is filtered. Therefore it is simple in operation and conformity with the requirement of GMP.
※ The drying speed is fast and the temperature is uniform, in general the drying time is 20~30 minutes each batch.
