Analysis of the effect of ZDG vibrating fluidized bed dryer on materials
After the material enters the equipment, it is subjected to directional vibration force and upward hot air to form a uniform fluidized state, which changes the material state from multiple dimensions such as conveying, heat transfer, shape protection, and purity control.
Vibration provides continuous throwing thrust, pushing the material to move forward at a constant speed, avoiding accumulation, channeling, and dead beds. The particles have no long-term retention differences and move as a whole close to piston flow. Wet material clumps can be slightly dispersed by vibration, ensuring that each batch of materials stays for a uniform duration and the drying moisture content is uniform and controllable.
ZDG vibrating fluidized bed dryer, hot air penetrates the fluidized bed layer, and the material particles are in full contact with hot air in all directions, greatly increasing the heat and mass transfer area. The bed temperature is not locally overheated, and the internal moisture is gently removed. Compared with ordinary drying equipment, the heat exchange is more complete, reducing the damage of high temperature to thermosensitive materials.
The mechanical vibration force is soft, the collision strength between particles is low, brittle and fragile materials are not easily broken, irregular particles can also be stably fluidized, and the integrity of the finished product is high; The amplitude and layer thickness can be adjusted, suitable for various materials such as powder, particle, and strip.
The ZDG vibrating fluidized bed dryer operates in a closed state, with vibration only driving material displacement and no dust leakage. The tail gas is matched with dust removal to recover fine powder, which not only avoids material loss but also isolates external impurities from entering, ensuring material cleanliness. After drying is completed, the cold air can be switched to synchronously cool the material, reduce the discharge temperature, and prevent residual heat from returning to moisture and clumping.
