The heat drying machine is the last piece of equipment in our PET washing line’s drying operation, capable of lowering moisture levels to around 3%. Hot air is used to dehydrate water from PET flakes in thermal dryers. PET flakes are pulled out of the dewatering machine via a transport blower, which mixes wet PET flakes with hot air flowing through a lengthy line of stainless steel tubes. Ending with a cyclone separator that incorporates cool air, residual moisture is further minimised, and the PET flakes are then cooled for storage.
