Detailed description

Description:

The dryer consists of air filter, heater, fluidized bed, rotating segment feeder, cyclone separator, bag dust remover, high press, centrifugal fan and stage for operation. According to the different characters of different materials to be dried, the dryer can be equipped with both cyclone separator and bag dust remover or with either of them. General speaking, for those pellet materials with a large specific gravity, only a cyclone separator is needed. And for those granule or powder materials with a small specific gravity, a bag dust remover is needed and so is a pneumatic conveying device if possible. The dryer can also be equipped with a rotating segment feeder if required.

Application:

The dryer is suitable for drying pellet or granules materials such as raw materials for medicine, tablet granules, traditional Chinese medicine drink granules in pharmaceutical industry, plastic resin, citric and other powder or granules in chemical industry. It also can dry grain, corn embryo, feed etc. The most suitable diameter of the material is 0.2-3mm.

Principle of work:

Granules or pellet solid materials are fed into the fluidized bed dryer through the feeder. Filtrated clean air is heated and charged onto the bottom of the fluidized bed to contact with the solid materials on the distributing plate, where fluidization can be reached and the heat exchange between solid and air can be achieved. After being dried, the products are discharged from outlet. Waste gas is disperse from the top of the fluidized bed, and powder materials are recovered by the cyclone separator or bag dust remover.
