QuadPass™ Rotary Drum Dryer
The revolutionary QuadPass dryer is an ideal solution for
• Agribusiness Industries
• Forest Products Industry
• Municipal & Industrial Wastes
• Animal Protein Recycling Industry
It’s unique, patent-pending design provides lower VOC emissions, more uniform drying, better product color and reduced fire danger compared to conventional single- and triple-pass rotary drum dryers. Here’s how:
Ordinary three pass drums (upper diagram) can over-dry. Material starts drying at high air velocity then drops at each stage, so particles can accumulate, overheat and clog.
The QuadPass™ Four-Zone Rotary Drum Dryer (lower diagram) starts at the slowest velocity, then gets progressively faster. This dries each particle of material at its individual drying rate, regardless of size, density or moisture. Dried particles exit the drum without overheating or volatilizing.
Complete turnkey systems include everything your application requires -- burners, material feeding and conveying equipment, recycle air systems, high-efficiency particulate collectors, and state-of-the-art PLC controls. Complete specifications
Drum replacement — The QuadPass rotary drum dryer is your fastest and most economical way to improve product quality, increase production, and reduce emissions. If your drums are broken, burned up, worn out, or don't meet production quality or quantity, we can replace any size, make or model with a new state-of-the-art drum using the same footprint.
