Patterson Kelley’s (PK) Tubular Vacuum Dryers (TVD) can process (dry and/or polymerize in the solid state) free-flowing solid material more rapidly than conventional vacuum dryers.

This is made possible by a greatly enhanced heat transfer surface area typically 3 to 7 times larger than similar sized traditional systems. Factors such as increased operating temperature and vacuum capacity also play an important role. The wide range of sizes available allow both high-volume processors and smaller-scale custom processors to enjoy the benefits obtained from using these dryers/solid states. Nylon and PET are among the polymers that have been successfully processed.
