Heated Cob Dryers
Compact, Elliptical-Bowl Dryers for Efficient Parts Drying and Polishing

Bel Air’s FGD Series Heated Cob Dryers combine powerful vibratory motion with uniform heated media to deliver fast, spot-free drying for metal and plastic components following mass finishing or cleaning operations.
Each unit features an elliptical-shaped process chamber that ensures 100 % part discharge and maximum heat transfer efficiency in a compact footprint—ideal for inline or batch production environments.
Designed for use with corn cob or agro-based drying media, these dryers gently remove moisture, light grease, and residue from finished parts while preventing damage or staining. A robust drive system, precision-balanced flyweights, and reliable heating elements make the FGD Series a durable, low-maintenance solution for any high-throughput finishing line.
Key Features & Benefits
- Elliptical bowl design ensures complete, efficient part discharge and reduces floor-space requirements.
- Side-loading chute enables smooth, ergonomic part transfer from vibratory finishing machines.
- Flap clearing system prevents part or media entrapment during separation for consistent results.
- Powerful vibratory drive system with sealed bearings and adjustable flyweights for maintenance-free, precision operation.
- Single or variable-speed motor options to match process requirements.
- Integrated heating elements provide uniform media temperature for quick, spot-free drying and light degreasing as corn cob absorbs residual oils.
- Compact, energy-efficient design minimizes operating costs and fits easily into inline or batch setups.
- Accessible process chamber simplifies cleaning and maintenance.
- Durable construction ensures longevity and reliability in continuous production environments.
- Automation-ready configuration supports pneumatic flap discharge and robotic handling systems.
