Granular material in the ordinary fluidized bed dryer for drying, the material particles should be uniform and have a certain size, or will form a ditch-like flow and stagnation area, the particle size distribution is wide, the entrainment serious, when the humidity is easy to caking , And because the particles back mixing, a large residence time distribution of particles, uneven moisture content of particles, thus limiting the use of ordinary fluidized bed dryer. In order to overcome its shortcomings, foreign countries to improve fluidized bed dryer performance has done a lot of research. Especially in the energy shortage today to strengthen mass transfer heat transfer process, energy conservation, improve quality, so that the fluidized bed dryer with a wide range of adaptability and economic rationality, vibration fluidized bed dryer is of great significance. Vibrating fluidized bed dryer is widely used in various industries because of its advanced design, reliable quality, wide application range, remarkable energy saving and the ability to dry materials that can not be dried on other dryers.

The vibrating fluidized bed dryer is vibrated by the vibrating motor to cause the machine to vibrate. The material is jumped under the action of the exciting force in the given direction. At the same time, the hot air inputted to the bottom of the vibrating fluidized bed drier makes the material fluidized State, material particles and hot air full contact, so as to achieve the desired drying effect. The material enters from the vibrating fluidized bed dryer inlet, and the material on the vibrating fluidized bed drier vibrates in the orthogonal contact with the hot air passing through the lower part of the vibrating slot, and the wet air is led out by the draft, discharge. In this case,

Vibrating fluidized bed dryer is widely used in the drying, cooling and humidifying of powdered and granulated materials in chemical, light industry, medicine, food, plastic, grain, oil, slag, salt, and sugar industry. For dry cooling, cooling and humidification operations. Its characteristics are as follows:

1, vibration fluidized bed dryer with vibration motor drive, smooth operation, low noise, long life, easy maintenance. In this case,

2, the vibration of fluidized bed dryer vibration to the material easy to reach the fluidized state, increasing the effective heat transfer coefficient, so the high thermal efficiency. Bed temperature uniformity, no local overheating. Uniform fluidization, no dead ends and blowing through the phenomenon. Vibration from the transport effect, but also conducive to energy conservation. Than the general drying device can save 30-60%. In this case,

3, material layer thickness and machine movement speed and amplitude can be stepless adjustment, adjustable, and speed with wide. In this case,

4, material surface damage is small, can be used for fragile materials, dry, irregular particles can also be used, does not affect the results. In this case,

5, vibrating fluidized bed dryer with fully enclosed structure, effectively preventing the material and the outside world of cross-contamination, clean environment, improved working conditions. In this case,

6, the vibration to promote fluidization, so that air requirements reduce the particle entrainment rate
