Holoflite and screw dryers use twin intermeshing screws or hollow paddles to convey material through a heated trough while maintaining excellent thermal contact. This low-temperature, indirect drying method is ideal for moisture removal in temperature-sensitive or hazardous materials without risk of combustion or product degradation.

Primary uses across industries

• In chemical processing, these dryers handle pigments, plastic pellets, salts, and fine chemicals.
• In wastewater treatment, they dry sludge for volume reduction and disposal.
• In pharmaceutical manufacturing, screw dryers are used for drying powders and intermediates under controlled conditions.
• In mining and metallurgy, Holoflite dryers process concentrates and tailings with high solid content.
• In food processing, they are used for drying protein pastes, starches, and other thick or sticky materials.

Types of materials processed

• Moist solids, sludges, and sticky pastes
• Granules, crystals, and powders sensitive to high temperatures
• Hazardous or flammable materials requiring indirect heating

Common materials of construction

Holoflite and screw dryers are built for corrosion resistance, heat transfer, and durability:

• Stainless steel for sanitary or corrosion-sensitive applications
• Carbon steel for general industrial use
• Specialty alloys for high-temperature or abrasive materials

Key features of Holoflite and screw dryers

• Indirect drying via hollow screws or paddles for controlled heat transfer
