Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the utility model, but the present invention is not limited thereto.

As shown in fig. 1, the hybrid drying device for small workpieces provided by the utility model comprises a heating fan 7, a temperature control module, an exhaust fan 4, a ventilation pipeline, an air knife 2, a drying chamber 1, a box body, a hydrocarbon concentration sensor 5, a vacuum pump 3, a vacuum gauge 6, a material tray 9, a driving motor 8, a controller and the like. The whole mixing and drying device is arranged in the box body, the middle part of the box body is a drying chamber 1, and a door plate of the drying chamber 1 is provided with a glass observation window. The upper part and the lower part of the drying chamber 1 are respectively equipment chambers. Two side walls of the drying chamber 1 are respectively fixed with a plurality of air knives 2 which are arranged side by side, the outer side of each air knife 2 is one end of a ventilating duct, and the other end of each ventilating duct is connected with a heating fan 7.
