Hot Air Paste Materials Paddle Dryer System Low Environmental Pollution

Product Description:

Our Hot Air Paste Materials Paddle Dryer System is a specialized agitation dryer designed to handle high-moisture paste, slurry, and granular materials while maintaining strict environmental standards. As a horizontal, low-speed drying solution, it utilizes internal stirring paddles to ensure wet materials come into full contact with heat carriers.

Classified as a hot air type paddle dryer, this system is engineered to provide stable operation with minimal gradients in temperature and humidity, ensuring the highest process stability for your production line.

• Low Environmental Pollution: The system is designed so that dust entrainment is kept to a minimum, ensuring a clean working environment.

• Minimal Solvent Evaporation: For contaminated materials, solvent evaporation is kept very small, facilitating easier processing and potential recovery through closed-loop systems.

• Wedge-Shaped Self-Cleaning Blades: The stirring heat transfer blades feature a self-cleaning function that removes adhering material through a washing effect.

• High Thermal Efficiency: Densely arranged hollow blades provide a large heat transfer area per unit volume, ensuring all heat is effectively used to heat the material.

• Sealed Construction: The Ω-shaped shell features sealed end caps and a top cover to prevent material dust leakage.

Why This System is Ideal for Paste Materials

• Piston Flow Movement: Material moves along the axial direction in a "piston flow," which is critical for maintaining uniform quality in thick pastes.

• Compression-Expansion Stirring: The special stirring effect of the wedge-shaped blades ensures that even viscous particles stay in full contact with the heat transfer surface.

• Wide Temperature Range: The system supports heat transfer medium temperatures ranging from -40℃ to 320℃.

• Low Operating Costs: Its robust structure minimizes wear and tear, resulting in very low maintenance and operational expenses.

FAQ

Q: How does the system prevent pollution during paste drying?

A: By minimizing air usage and utilizing a sealed Ω-shaped shell, the dryer prevents dust leakage and limits solvent evaporation to a manageable level.

Q: Can this system handle highly heat-sensitive pastes?

A: Yes. The uniformity of temperature and humidity within the axial range allows for safe processing of heat-sensitive materials.

Q: What heat media can be used in the hot air type system?

A: Common media include steam, thermal oil, hot water, or cooling water flowing through the rotary joints and shell jacket.
