What are the special advantages of vibrating fluidized bed dryers

- Jul 04, 2018-

As a drying device, vibrating fluidized bed dryers have a special role and are generally used for the final drying of materials. Since the vibrating fluidized bed dryer can fluidize the material by means of mechanical vibration during the drying process, it not only facilitates turbulence at the boundary layer, enhances heat and mass transfer, but also ensures that the drying equipment maintains normal operation under relatively stable flow mechanics conditions. .


For the user, the vibrating fluidized bed dryer not only has a good drying function, but also can be accompanied by processes such as material granulation, cooling, sieving and conveying according to the process requirements. For the time being, the equipment has been widely used in industrial sectors such as sugar, medicine, fertilizer, chemicals, plastics, dairy, salt, and mining and metallurgy. At present, horizontal structures are often used in the structure.


In fact, compared with the conventional horizontal fluidized bed dryer, the horizontal vibrating fluidized bed dryer has similar appearance and basic structure. The main difference is that the whole body is supported by the spring on the base. Slightly inclined to the discharge end, a vibration motor is mounted on one or both sides of the body. The material is fluidized by the action of mechanical vibration and perforated airflow, and moves forward under the action of vibration.


In practical applications, the superiority of the horizontal vibrating fluidized bed dryer equipment is mainly reflected in two aspects: one is to obtain uniform fluidization at a very low gas velocity, thereby greatly reducing energy consumption and intergranularity. The wear and dust entrainment; the other is that the material residence time is evenly distributed, so it is regarded as "piston flow", and the residence time of the material is easy to adjust and control, thus obtaining a very ideal product moisture content.


Moreover, during the use of the horizontal vibrating fluidized bed dryer, the material can be uniformly heated, not only the drying strength is high, but also the quality is good. The horizontal vibrating fluidized bed dryer has small damage to the surface of the material and can be used for the drying of fragile materials. When the material particles are irregular, the working effect is not affected. At the same time, it adopts a fully enclosed structure to keep the materials and the working environment clean.
