摘要：
The present invention relates to a drying process which comprises the following steps: (1) charging the polymer material in bulk into a drying apparatus which comprises a drying chamber and a rotary device; and (2) drying the material by rotating at high speed and during a predetermined time the rotary device which includes a plurality of blades coupled to the drive means so that the polymer material dries by friction heating caused by intercollision of polymer material particles between each other as well as by impingement of material against the walls of the drying chamber.
摘要（中）：
本发明涉及一种干燥方法，其包括以下步骤：（1）将聚合物材料批量装入包括干燥室和旋转装置的干燥装置中; 和（2）通过高速旋转和在预定时间期间旋转材料来干燥材料，所述旋转装置包括多个叶片，所述多个叶片联接到驱动装置，使得聚合物材料通过由彼此之间的聚合物材料颗粒彼此夹入而引起的摩擦加热而干燥 以及通过冲击材料抵靠干燥室的壁。
