The clean hot air is distributed into the bed through the valve plate, and the wet material entering from the feeder is formed into boiling state by the hot air. As the hot air is in contact with the material, the process of heat and mass transfer is enhanced, so it can be dried in a short time. If the continuous type is used, the material enters from one end of the bed, boils and dries after tens of seconds to minutes, and automatically flows out from the other end of the bed. This equipment is generally operated under negative pressure.

Characteristics of equipment

Boiling drying, also known as fluidised bed, it is by the air filter, heater, boiling bed host, cyclone separator, bag duster, high-pressure centrifugal fan, the operating table, due to the nature of the drying material is different, supporting dust removal equipment, according to the need to consider, you can choose the same time, cyclone separator, bag duster, or choose one of them, in general, the specific gravity of the larger, such as the punch and granular drying only need to select the Cyclone separator, lighter specific gravity of small granular and powdery materials need to be matched with the bag duster, and there are pneumatic feeding device and belt conveyor for choice.
Bulk solid materials are added into the fluid bed dryer by the feeder, and the filtered clean air is sent into the bottom of the fluid bed by the blower after heating to contact with the solid materials through the distribution plate, forming fluidisation to achieve the heat and mass exchange of gas and solid. After drying, the material is discharged from the discharge port, and the exhaust gas is discharged from the top of the boiling bed through the cyclone dust collector group and the cloth bag dust collector to recover the solid powder and then emptied.
Steam, electricity, hot air furnace can be equipped (according to user requirements).

Scope of application

The drying operation of pharmaceuticals, chemical raw materials, foodstuffs, food processing and feedstuffs. Such as: raw materials, tablets, granules, traditional Chinese medicine, health food, beverage preparation, corn germ, feed, plastic resin, citric acid and other powdery materials drying dehumidification. Applicable materials particle size is generally 0.1 ~ 6mm, particle size is 0.5 ~ 3mm.

Installation instructions

◎ The equipment should be placed flat, fixed with foot screws, and the parts should be well sealed.
◎ The fan can be placed outdoors or in a self-constructed silencer room. The layout can be adjusted according to the specific situation.
