The advantages of a horizontal multi-chamber fluidized bed dryer are as follows: 1. The structure is simple, the manufacture is convenient, and there are no moving parts; 2. Small footprint, easy to discharge and easy to operate; 3. High drying rate and high elasticity; 4. For heat sensitive materials, use a lower temperature for drying and the particles will not be destroyed. Of course, horizontal multi-chamber fluidized bed dryers also have shortcomings: 1. Thermal efficiency is lower compared to other types of fluidized bed dryers; 2. It is less adaptable to multi-species small yield materials. In order to overcome the shortcomings of appeal, the commonly used measures are: 1. With a grid feeder, the material can be spread as evenly as possible over the bed; 2. Smooth processing in the dryer, preferably with rounded corners, eliminating the dead angle of each chamber orifice; 3. The operation strives for stability. Oxygen vibrating feeders are sometimes used to make the bed fluidized and stable.
