The NEUE HERBOLD - step dryer Series T are used for gentle drying of Kunststoffmahlgütern from PET plastic. Besides these PET regrinds this aggregate shall be dried gently other ground materials also capable.
They are suitable for deposition of the surface moisture from the granular plastics. Depending on the temperature, size and structure of the ground material to be dried, a surface residual moisture content of about 1 to 2 weight percent is achieved.
The ground material / water mixture is fed to the drying chamber via the feed screw. In the dryer, the ground material is detected by a tipped blades with special rotor and transported through the step-shaped strainer. This increase in diameter, the ground material at the entrance is only slightly accelerated to then be accelerated from stage to stage more and thus throw off the adhering water particles (centrifugal)
