Injection molding material drying device

The invention belongs to the technical field of drying equipment, and particularly relates to an injection molding material drying device which can uniformly and effectively stir injection molding materials through cooperation of a stirring mechanism, an outer barrel, an inner rotating barrel and other parts after the injection molding materials are produced and cleaned, so that clustered materials can be dispersed, and drying treatment is facilitated. Through the arrangement of an air inlet and an air extraction opening, materials in the inner rotary barrel can be conveniently and effectively dried by inputting hot air and extracting air to form vacuum, meanwhile, re-condensed moisture after heating can be better drained, and the situation that the drying efficiency and effect are affected due to moisture backflow is avoided; and the assistor can further enable the stripping rod to assist in distributing the materials, so that the drying efficiency and effect are improved. 本发明属于烘干设备技术领域，具体涉及一种注塑材料烘干装置，能够在注塑材
