FG Vertical Pharmaceutical Fluid Bed Drying Machine ( Fluid Bed Drying Machine ) (Fluid Bed Dryer)( FBD Ddryer )

FG-B fluid-bed dryer and FBG 2 bar shock resistance fluid bed dryer are popularly used for powder and particles drying in pharmaceutical, food, feed, chemical industries. A fluidized bed is a bed of solid particles with a stream of air passing upward through the particles at a rate great enough to set them in motion. As the air travels through the particle bed, the particles behave as boiled water. The active motion creates the potential for improved mixing and results an isothermal property. In a bubbling fluidized bed, no temperature gradient exists within the mass of the fluidized particles. Because the temperature and volume of the air can be precisely adjusted, the process achieves fast heat transfer making it very efficient, yet gentle on the product.

Preface

Fluidized bed drying can be used in the entire powder processing industry. In the pharmaceutical industry, this innovative method has replaced the time-consuming tray drying long ago: The drying process with fluidized bed drying reduces the drying time in the drying oven by approximately twenty times. In addition, fluidized bed drying provides controlled and uniform drying conditions compared to the uneven drying in trays.

For the process variants spray granulation, spray agglomeration or spray coating, it should be noted that not only the moisture needs to evaporate until it has reached a defined residual value, but also that drying takes place during the entire spray process. Too high inlet air temperatures can lead to insufficient liquid bridges, instable granulate structures or inhomogeneous looking films.

Feature :

The structure of fluidization bed is of round so as to avoid dead corner. Inside the hopper there is a stirring device in order to avoid agglomeration of raw material and forming canal of flow. The granule is discharged through the method of turning over. It is very convenient and full. The discharged system can be designed as request.

It is operated at the conditions of negative pressure and seal. The air is filtered. Therefore it is simple in operation and convenient for cleaning. It is an ideal equipment that is in conformity with the requirements of GMP.
