Cleaned plastic needs to be dried completely before further processing – even a small amount of moisture can stress the degassing systems. Thick-walled plastics are easy to dry. But thin film, with its extremely large surface area, presents a considerable challenge.
Pla.to Thermal Dryers achieve outstanding drying results by applying hot air to the wet plastic in a highly intensive process. The machine surfaces are thermally insulated to minimise heat losses.
The heat is generated through either
A heat exchanger is used to prevent the combustion gases from coming into contact with the plastic. This so-called indirect hot air generation provides optimal security against accidental fires.
