For indirect, efficient heat transfer and controlled drying of sludges, pastes, powders, and granular materials, Holoflite and screw dryers provide a compact and energy-efficient solution trusted across industries. With over 47 years of process equipment expertise, IPP offers immediate access to high-quality used screw dryers and Holoflite units sourced from 20 complete plant sites and included in our inventory of over 15,000 ready-to-ship pieces of equipment. Buying used from IPP helps companies minimize lead times, reduce energy usage, and improve operational performance.

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
Energy-efficient operation with minimal gas or vapor emissions
Compact footprint with continuous feed and discharge
Closed-loop or inert gas options for hazardous materials
