Fluidized bed dryer for fluidization drying is a kind of commonly used drying equipment, and its working principle is to use hot air to dry materials. Fluidized bed dryer consists of air filter, heater, fluidized bed host, cyclone separator, bag duster, high-pressure centrifugal ventilator, operating table and so on. According to the different nature of materials, cyclone separator or cloth bag duster can be selected as needed.
In the fluidized bed dryer, the material is added to the fluidized bed dryer by the feeder, and the filtered clean air is sent to the bottom of the fluidized bed by the blower, and then contact with the solid material through the distribution plate, and form the fluidization 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 fluidized bed through the cyclone dust collector group and the bag dust collector to recover the solid powder and then emptied.
Fluidized drying fluidized bed dryer has the following characteristics:
Automatic production can be implemented, is a continuous drying equipment.
Fast drying speed, low temperature, can ensure the quality of production, in line with the requirements of pharmaceutical production GMP.
The particle size of the material is generally 0.1-6mm, and the best particle size is 0.5-3mm.
Adapted to the drying operation of the materials such as pharmaceuticals, chemical raw materials, foodstuffs, food processing and feedstuffs.
The residence time of materials in the equipment can be controlled by adding or subtracting materials.
Simple structure, convenient operation, less maintenance.
It can be used for drying larger granular materials, etc.
In short, the fluidized bed dryer of fluidized drying is a kind of drying technology with high efficiency, stability, and in line with the requirements of pharmaceutical production, and it is suitable for drying operations of a variety of materials.
