Industrial Drying Equipment

Fluid bed size (L×W) 8000×1500mm
Vibration motor power 5.5×2kW

The fluid bed dryer applies mechanical vibration to a conventional fluidized bed system, improving material movement and heat exchange efficiency. Under the combined action of vibration and airflow, the material enters a fluidized state and moves continuously along the bed.

As hot air passes through a perforated distribution plate, it makes direct contact with the material, facilitating effective heat and mass transfer. By adjusting vibration parameters, the drying system can achieve a more uniform plug flow, overcoming the back-mixing typically seen in standard fluidized beds during continuous operation.

Features

Equipped with a vibration motor, the drying system reduces the minimum fluidization velocity, significantly lowering the volume of heated air required and minimizing dust entrainment. This also helps reduce the size and cost of supporting equipment.
The fluidized state allows for full contact between material and hot air, ensuring uniform drying with a high heat transfer coefficient and notable energy savings.
Offers excellent process flexibility, allowing the residence time to be adjusted based on material characteristics for optimal drying performance.

Application

Fluid bed dryers are widely used for drying chemical raw materials and finished products, pharmaceutical powders, as well as food additives and flavoring agents. Their efficient heat and mass transfer capability makes it suitable for a broad range of temperature-sensitive and particulate materials.

What is the difference between a standard fluidized bed and a vibrating fluidized bed?

A standard fluidized bed relies solely on air velocity to suspend and move materials through the evaporator. In contrast, a vibrating fluidized bed uses mechanical vibration to assist material movement, improving flow consistency and control, especially for challenging or sticky materials.

What is the operating temperature range for a fluid bed dryer?

Typical inlet air temperatures range from 300°F to 1500°F (150°C to 815°C), while exhaust air temperatures usually fall between 170°F and 250°F (77°C to 120°C), depending on the material and drying requirements.

Does solid mixing occur inside a fluid bed dryer?

Yes. Fluid bed dryers are considered continuously stirred tank reactors (CSTRs) due to the thorough mixing of solids. If additional agitation is needed, mechanical stirrers can be incorporated into the design.
