With the development of fluidized drying application technology, various types of fluidized bed dryers have been produced and are widely used in industrial production such as chemical engineering, light industry, medicine, and food.
Fluidized bed dryer is the simplest type of single cylinder, has been used in ammonium sulfate, ammonium chloride, anhydrous sodium sulfite, salt, polytetrafluoroethylene, calcium gluconate, alkaline Qinglian dye, catalyst particles and other materials Drying. The dryer is relatively simple to operate. The disadvantage is that the residence time of the material in the fluidized bed is widely distributed, and the humidity of the resulting product after drying is not uniform.
The multi-layer fluidized bed dryer overcomes the disadvantages of the single-layer fluidized bed dryer, the residence time distribution is greatly narrowed, the product is dried uniformly, and the drying quality of the product is easily controlled. Due to the reduced residence time and high thermal efficiency, it is suitable for drying materials with longer drying stages and drying with higher moisture contents. Has been used in polyester chips, sodium salicylate, aminopulin, terramycin, chlortetracycline, tetracycline, tablet starch granulation, powdered sugar and other materials drying.
The drying time of the horizontal multi-chamber fluidized bed dryer can be arbitrarily adjusted, and a dry uniform product can be obtained. Applicable to the drying of various difficult-to-dry powder materials and heat-sensitive materials. Such as polyvinyl chloride resin, polypropylene resin, nylon 1010, o-chlorobenzoic acid, oxytetracycline, chloramphenicol, tetracycline, powdered sugar and other materials dry.
Stirred fluidized bed dryers are equipped with agitators in the fluidized bed so that certain wet particulate materials or materials that can easily agglomerate can also be fluidized and dried. It can be used for the drying of materials such as ammonium sulfate, copper sulfate, sodium fluoride, amino acids, anhydride casein, polypropylene resin, and phenolic resin.
The vibrating fluidized bed dryer is a very successful modified fluidized bed. The mechanical vibration is added to the fluidized bed. The bed material is mainly moved by vibration and the gas is only used for heat transfer and mass transfer. Compared with general fluidized bed, it can reduce the air volume and air pressure needed for fluidization. Mainly used in the mining, metallurgy, chemical, pharmaceutical, food industry, such as sugar, asbestos, milk powder and other materials drying.
There is also a belt fluidized bed dryer which is equipped with a belt conveyor on the bed surface of the fluidized bed and moves forward with the material. When hot air is blown into the bed, the material is fluidized or ventilated, causing surface moisture to evaporate. Has been widely used in compound fertilizers, calcium carbonate, clay, kaolin, clay soil, grain, distiller's grains, activated sludge and other materials drying.
According to the needs of production, the fluidized bed drying equipment is continuously improving, and the application range in the industry is also increasing.
