FG Vertical Fluidiz Bed Dryer with cooler FBD Fluid bed drier

The so-called fluidized bed refers to a equipment, the particulate material stacked on the distribution board, when the air flow from the lower part of the equipment into the bed, with the airflow speed increases to a certain extent, solid particles in the bed will produce boiling state, this bed is called fluidized bed. Dry by this method is called fluidized bed drying. This drying is mainly used for the drying of wet granular materials, such as tablets, granules and other particles. It has the advantages of high drying efficiency, uniform drying, high yield, suitable for the continuous production of the same variety, and low temperature, convenient operation, small footprint and so on. But the drying room is not easy to clean, especially unfavorable for the drying of colored particles, and the proportion of fine powder after drying is large.

According to the above meaning, when the use of hot air as fluidized medium, in dry food wet materials, hot air is both fluidized medium, and drying medium, plays a double role. On the one hand, the dry air flow is blown, rolled, mixed, friction and collided, and on the other hand, heat and mass transfer, so as to achieve the purpose of drying. The principle of boiling drying is to use the hot air blowing from the bottom of the fluidized bed to float the particles. The fluidized rolling is like "boiling", the beating of the material greatly increases the evaporation surface, the hot air through the suspended particles, in the dynamic heat exchange, take away water, to achieve the purpose of drying. If the decompression boiling drying, the drying efficiency is higher.
