Heyl Patterson Thermal Processing: Expertly-Designed Dryers & Coolers for the Powder, Bulk Solids Processing and Material Handling Industry.

Rotary Dryers & Coolers
Considered the workhorses of the thermal processing industry, nothing beats the ruggedness and versatility of rotary dryers and coolers. Heyl Patterson’s rotary dryers and coolers efficiently process a wide range of materials, from clumped solids to liquid sludges, due to lifting flights specialized for each material. Customize your rotary dryer or cooler by specific starting and final moisture requirements, material temperature limits, air velocity, and retention time.

Fluid Bed Dryers & Coolers
Perfect for free-flowing materials, Heyl Patterson’s fluid bed dryers and coolers are some of the largest in the world. Capable of a high rate of heat transfer and gentle handling of material, fluid beds can be fine-tuned for maximum efficiency specific to each material. Heyl Patterson Thermal Processing offers three main types of fluid beds: Vibrating, Circular Type, and Trough Type.

Flash Dryers
A flash dryer is often the perfect solution when a high moisture, temperature-sensitive, or very fine material needs to be dried quickly. Heyl Patterson flash dryers ensure each particle’s drying time is proportional to the size and weight, leading to a thoroughly dried and degradation-free end product. Flash dryers are also available in a Rotacurrent or Venturijet design.
