Principle of FG Series High-Efficiency Fluidized Bed Dryer:
After heating, the purified air enters from the bottom of the fan and passes through the mesh plate of the shield. In the working chamber, the material is fluidized and stirred under negative pressure. Subsequently, the moisture in the material rapidly evaporates, and it will be carried away by the exhaust gas as the material dries quickly.
Features of FG Series High-Efficiency Fluidized Bed Dryer:
● The fluidized bed has a circular structure to avoid blind corners.
●The bunker is equipped with a stirrer to prevent the wet material from forming clumps and channels during rolling and drying.
● Equipped with a tilting discharge device, the advanced potassium phosphate dryer allows the machine to easily, quickly, and thoroughly discharge materials. Additionally, we can design automatic loading and unloading systems according to requirements.
●Utilizing this characteristic for negative pressure sealed operation, filtering airflow, simple operation, and easy cleaning, this machine is an ideal piece of equipment that meets GMP requirements.
●This machine features high drying speed and uniform drying temperature. In the potassium phosphate dryer process, the drying time per batch is generally 20 to 30 minutes.
FG Series High-Efficiency Fluid Bed Dryer Application Scope:
●Machining screw extrusion pellets, shaking pellets, wet rapid mixing pellets.
● It is used for drying wet granules and powdered materials in industries such as pharmaceuticals, customized potassium phosphate dryers, food processing, feed processing, and chemicals.
●Large particles, potassium phosphate dryer, clumps of small pieces, sticky blockages, or granular substances.

Working principle of horizontal multi-chamber fluidized bed dryer:
When this type of dryer is used for drying materials, the material is fed from the hopper into the first chamber by the feeder, where it is impacted and scoured by intense hot airflow. The velocity of the material continuously fluctuates, promoting turbulence in the airflow boundary layer and enhancing the rates of heat and mass transfer. Additionally, the contact surface between the airflow and particles is very large, resulting in a high volumetric heat transfer coefficient. Moreover, the particles can achieve complete mixing in the fluidized bed. As long as the airflow velocity is maintained between the critical fluidization velocity and the particle settling velocity, the particles can form a fluidized state in the bed, bouncing up and down, mixing and colliding with each other in the hot airflow. This facilitates mass and heat transfer with the hot airflow, thereby achieving the purpose of drying.
The bed body of a horizontal multi-chamber fluidized bed dryer is typically designed as a rectangular shape. In the longitudinal direction, vertical baffles divide the bed body into multiple chambers (the number of baffles is determined based on material calculations). A certain gap is left between the bottom of the baffles and the porous distribution plate, allowing the material to be dried to pass through each chamber sequentially. Several hot air inlets are evenly distributed at the bottom of the porous distribution plate of the bed body to supply drying hot air for drying the material. The dried air is drawn out from the top of the bed body, and the dust in the air is separated by a cyclone before entering the dust removal chamber for further cleaning. The cleaned air is then pulled out of the chamber by an induced draft fan, while the dried coarse material is discharged through the coarse material outlet. Its structural features include the ability to adjust the temperature of the hot air entering each chamber, the residence time of the material in the fluidized bed, and the feed rate. Additionally, the pressure drop of the airflow is low, making the operation not only easy but also highly stable. It is commonly used for drying materials with particle sizes ranging from 0.02 to 4 mm.
