Understanding Paddle Dryer Technology

How Indirect Paddle Dryers Work

• Feed wet cake, paste, or slurry at the inlet
• Jacket and paddles heat via steam/thermal fluid
• Paddles agitate, advance, and spread product for optimal contact
• Vapors escape via exhaust vents
• Fully dried output exits continuously

Key Benefits of Choosing Paddle Dryers

• Exceptional energy efficiency from indirect heating
• Ultra-low exhaust volumes—no carrier gas needed
• Total containment for odors, dust, and hazards
• Safe handling of flammable dusts
• Steady temperature profiles
• Consistent moisture control through agitation

Industrial Applications for Paddle Dryers

• Inorganic salts, catalysts
• Cellulose ethers, brominated compounds
• Starches, pigments

• Catalyst devitalization
• Refinery sludges
• Specialty powders

• PP, PC, PPS pellets
• PET, PTA, resin compounds

• Protein powders, flours
• Beverage extracts, confectionery
• Hemp fibers, biomass

• Powders, carbonates
• Sulfates, concentrates

• ETP sludges, filter cakes
• Hazardous wastes
