Applications: The machine uses screw to extrude, vibrate and smach granule with the method of humidity, high speed and mixing. It is applied in Pharmaceutical foodstuff, feed and chemical industries. The raw material is large in granule and small in block and having adhesive property. Features: The structure of fluidization bed is round so as to avoid dead corner. Inside the hopper there is a stir in order to avoid agglomeration of raw material and forming canal of flow; The granule is discharged through the method of turning over. In this way it is very convenient. The discharging system can be designed as requested. It is operated under the conditions of negative pressure and sealing. The air is filtered. Therefore it is simple in operation and convenient in cleaning. It is an ideal equipment that is in 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. 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 evaporated and removed rapidly and the raw material is dried quickly.
