Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic masterbatch drying, in particular to a plastic masterbatch drying device. Background Art
[0002] The drying process of masterbatch generally uses a hot air blower to remove moisture from the surface of the masterbatch by hot air. In order to prolong the drying process, an inclined guide plate is generally added inside the drying equipment. After the masterbatch enters the drying equipment, it enters multiple guide plates in a graded manner. By improving the flow path of the masterbatch, the effective drying time of the masterbatch is increased. However, the dryer generally adopts one-sided ventilation.
