Dryers & Coolers

Heyl Patterson Thermal Processing has been building customized and dependable dryers and coolers for the powder and bulk solids industry since 1874. This experience and knowledge is spread through the entire team designing and building every piece of equipment, keeping us innovative and as efficient as possible. For drying and cooling, Heyl Patterson offers customers three main product lines, each perfectly suited for specific applications and materials. We won’t try to force a specific technology, and work with customers to find the solution that will work best, even for otherwise difficult to handle materials.

Rotary Dryers & Coolers

Nothing beats the ruggedness and versatility of Rotary Dryers and Coolers, which are used as the workhorses of the thermal processing industry.  Heyl Patterson’s rotary dryers and coolers can efficiently handle a wide range of materials, including everything from clumped solids to liquid sludges due to lifting flights specialized for each material.  Able to be customized to the specific starting and final moisture requirements, material temperature limits, air velocity, and retention time, a rotary dryer or cooler will be perfectly built for each individual application. 

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 individual material.  Heyl Patterson offers three main types of fluid beds: Vibrating, Circular Type, and Trough Type.

Flash Dryers

When a high moisture, temperature sensitive, or very fine material needs to be dried, a flash dryer is often the perfect solution.  Heyl Patterson flash dryers ensure each particle’s drying time is proportional to the size and weight, leading to an end product thoroughly dried and free of degradation.
