Fluidized bed drying equipment has the following specific characteristics. The drying equipment is suitable for drying bulk materials without agglomeration.

The particle size range is 30um-6um. The drying equipment has simple structure and large production capacity, tens of thousands of kilograms per hour.

Up to 400,000 kg; thermal efficiency is about 70%, used to remove moisture from materials, thermal efficiency is about 30%-50%, and the volumetric heat transfer coefficient can reach 2326-6978W/(m?.℃).

The residence time of the material in the flowing fluidized bed is related to the structure of the fluidized bed. If the design is reasonable, the residence time of the material in the fluidized bed can be extended arbitrarily.

The disadvantage is that the hot air resistance through the distribution plate and the material layer is relatively large, usually about 490-1470Pa. The energy consumption of the blower is large. For single-layer fluidized bed drying equipment, the materials are completely mixed in the fluidized bed.

Some materials from the feed port to the discharge port may short-circuit and fly directly to the outlet, causing uneven drying of the materials.

In order to improve the uniformity of material drying in the fluidized bed, fluidized beds with different structures are usually used. Single-layer fluidized bed with baffle structure, horizontal multi-chamber fluidized bed, multi-layer fluidized bed, etc., can control material short circuit.
