The centrifugal and hot-air dryer trial in Finland shows two stages of plastic drying. The spin dryer uses centrifugal force to remove bulk water. The material then passes through a hot-air stage to reduce the remaining moisture.
Why dewatering comes before hot-air drying
The same sequence is used for washed PET flakes. Mechanical dewatering reduces the amount of water the thermal stage must handle, while the hot-air system addresses moisture left on the material.
