Vibro-fluidized Bed Dryer
Drying Equipment
1. Product Overview
The vibrating fluidized bed dryer builds on the conventional fluidized bed by adding vibrating motors. It consists of a vibrating trough, excitation motors, isolation springs, air plenum, heater, cyclone separator and control accessories. Typical applications: chemical granules, mineral powders, salt, MSG and fertilizers. Key features: handles agglomerating or hard-to-fluidize materials, uniform residence time, low particle breakage, and adjustable inclination to control the discharge rate.
2. Working Principle
Wet material enters the trough through the feed port. The vibration motors generate high-frequency, low-amplitude oscillation while hot air is supplied from below through the distribution plate. Under the combined action of vibration and airflow, the material leaps in a fluidized state and advances along the bed in plug flow; moisture evaporates rapidly and the dried product discharges at the outlet.
3. System Classification
By Trough Structure:
Straight Trough Vibrating Fluidized Bed: Horizontal layout with linear material movement / Conventional granules and crystals
Stepped Vibrating Fluidized Bed: Stepped bed surface for more intensive tumbling / Sticky, agglomeration-prone materials
Multi-layer Vibrating Fluidized Bed: Vertically stacked layers that save floor space / Long residence time required, space-constrained installations
