General description of Vibrating Fluid Bed Dryer: ZLG series Vibration Fluid Bed Dryer is a continuous Drying Equipment for non-sticky particles. Its working principle is: cold air is filtered through the filter, and then goes into the heater, and is heated to a certain temperature, then hot air is distributed into the lower bed via multiple inlets and flows up through perforated plate of the bed. Material goes evenly into the bed through screw feeder, under the action of the vibration force, the material moves up forward continuously along the horizontal direction, while undergoes heat exchange with the hot air coming up from bottom, the moisture of material is evaporated rapidly, and the wet air is discharged from the exhaust fan, and the material is fully dried and discharged from the discharge port.
Application of vibrating Fluid Bed Dryer:
Industrial Vibration Fluidized Bed Dryer applicable to chemical, pharmaceutical, food, dehydrated vegetables, food, minerals and other industries powder, granular materials, dry, cooling and other operations.
Such as: citric acid, monosodium glutamate, borax, ammonium sulfate, compound fertilizer, radish l, silk, soybean meal, lees, seeds, slag, sugar
Design condition of vibrating fluid bed dryer:
1. The drying time is short, only takes several minutes for the whole drying process, the general effective ingredients will not be destroyed.
2. Adjustable weir plate is set at the discharge port, by adjusting the height of the weir plate, you can control stayed drying time of the material so as to make sure that final water content of materials meets the requirements.
3. Perforated plate adopts back pressure process to ensure flatness of perforated plate, to avoid the deadline in the process of material running.
4. There are multiple wind inlet to the lower bed, so that the hot air through the material layer is more uniform.
5. The whole electric heating treatment is applied to the lower bed after its completion of production, eliminating the welding gravity, improving the strength of the bed, thick-walled seamless tube is applied to the internal to strengthen the evenly vibration force.
6. The center tube which is equipped with vibration motor is welded with reinforcement plate according to the angle of vibration radiation, effectively passing vibration force evenly to the various parts of the bed, so that the material is uniformly fluidized, while equipped with removable weight, to avoid resonance phenomenon.
7. Shock absorber adopts quenched and tempered spring, compression performance and rebound performance are good, effectively filtering the vibration force to the ground, to overcome the defects of rubber shock absorber which is easy aging and short life, etc.
The upper bed is designed to be fixed, there is a soft connection with the lower bed, reducing the load of vibration motor, while reducing the strength of the upper bed.
8. A cooling section is equipped with the rear part, can quickly cool the material, the material can be packaged directly; cold air undergoes dehumidification first, and then heated up, reducing the cold air humidity, to ensure that the final water content of materials to meet the requirements, and the cold air temperature can be set according to the specific requirements .
9. The upper bed is equipped with a number of observation goggles and cleaning doors, easy to clean.
10. The upper bed adopts a number of stainless steel seamless steel pipes to strengthen, improving the strength, while on strengthening pipes there is no accumulated material.
11. The steam heater adopts seamless tube aluminum fins, and designed to U-shape, with external shell, so that the heating tube has room for thermal expansion and contraction, to avoid weld cracking phenomenon of the conventional heater with fixed heat pipe due to thermal expansion and contraction, while improving the heat transfer efficiency.
12. Adopts high efficiency long cone cyclone de-dust separator, greatly reducing the exhaust dust, so that the material yield can reach 98%.
