The pellets emerging from the pelletizer cutting chamber are carried by the process water through piping to  the centrifugal dryer. 

The pellets and residual water flow into the rotor section of the dryer. Both the speed of rotation and the design of the lifters inside the rotor cause the pellets to ricochet between lifters and screens while being conveyed by centrifugal action up the dryer rotor in a helical path. The water is separated through the screens and the pellets are continuously conveyed into the upper section of the dryer where they are discharged from the resin outlet.

The drying process reduces the residual moisture, depending on the polymer. Final drying is achieved in the upper two-thirds of the screen surface and in the pellet outlet chute of the dryer. Dry countercurrent air flow generated by an external exhaust fan removes the residual surface moisturefrom the pellets, assisted by the pellet internal temperature. The exhaust fan produces a slight vacuum which prevents humid air from exiting into the room or condensing in downstream equipment components.

The process water heated by the pellet flow is separated in the centrifugal dryer. The process water remains in the closed loop and is collected in the process water tank. A heat exchanger ensures constant water temperature. The process water is filtered and re-circulated to the pelletizer cutting chamber.
