Drying systems for recycled PET.

Based upon Buhler’s extensive experience in drying a wide variety of bulk products, the systems are designed for continuous thermal treatment of fluidizable flakes, granular materials and powders, and are therefore the best solution for all common forms of recycled PET.

Recycled PET pellets are used for repeat bottle manufacturing while recycled PET flakes are used for manufacturing packaging films and shells with direct food contact.
