Vibratory Fluidized Bed Dryer
The Vibratory Fluidized Bed Dryer is used for drying powders, granules, and tablets by combining controlled airflow with mechanical vibration. In this process, hot air passes through the material bed from below, lifting and spreading the particles so they behave like a fluid. This increases the surface area exposed to heat.
What makes this system different is the added vibration. The vibration helps move the material forward while keeping it evenly distributed, which improves drying consistency and prevents clumping.

- Adjustable Temperature: Inlet air temperature can be set between 70–140°C, while outlet temperature remains controlled between 40–70°C. Due to this, operators can handle heat-sensitive materials.
Vibratory Fluidized Bed Dryer Diagram. - Control Over Drying Speed: By adjusting airflow (0.5-2.0 m/s) and vibration amplitude (3-8 mm), operators can control how long materials stay inside the system. With it, you can achieve the desired moisture level.
- Multiple Heating Options: Supports steam, electric, or gas heating, making it easier to match existing plant utilities and reduce operational constraints.
- Handles High Moisture Loads: Capable of evaporating 20 to 500 kg of moisture per hour, depending upon the model.
- Easy to Operate: This machine includes a PLC control panel that makes it easy for anyone to control the entire process.

| Application: | Tablet drying, coated tablet drying, and granule drying |
Vibration: Two vibration motors (or exciters) generate synchronized linear vibration (vertical + horizontal components). Vertical force fluidizes particles; horizontal force conveys them steadily from feed to discharge.
Fluidization: Heated air flows upward through a perforated bed plate, suspending particles in a fluid-like state to maximize heat/mass transfer.
Drying & Conveyance: Materials dry as they move; moist air is exhausted and filtered; dry product discharges continuously.
- Food: Sugar, salt, flour, grains, snacks, food additives.
- Pharmaceutical: Pills, granules, herbal extracts, API crystals.
- Chemical: Fertilizers, pigments, polymers, rubber additives, catalysts.
- Others: Minerals, feed, tobacco, plastic pellets.Typical particle size: 30 μm – 6 mm.
From 10–40% down to 0.1–5%, depending on material and time.
Yes—many units can dry → cool in one line; some used for agglomeration with binder spraying.
10–15 years with proper maintenance; motors/springs 3–5 years.
