Plastic pellet dryer T-Series

The NEUE HERBOLD step dryer (T-Series) was especially designed for gentle drying of PET flakes.

It is suitable for the separation of surface moisture from granulated plastics. Depending on temperature, size und structure of the material it is possible to achieve a surface moisture of approx. 1– 2 percent of the material weight.

Function:
Through the pre-wash screw the flakes / water mixture is fed to the dryer. Inside the dryer the material is taken by a specially designed paddle rotor which transports the material through the cascade screen cage. In the beginning of the drying process there is only a slight acceleration of the material. Due to the diameter enlargement, the acceleration increases from step to step in order to spin-off the water particles. The special rotor and screen cage configuration ensures a gentle treatment of the material flakes, the fines are reduced to a minimum.
