These new materials are designed to meet the higher requirements of modern industry, aerospace, information technology, biomedicine and other fields. In the production and processing of new metal materials, hot air dryers are required to dry the new metal materials.

[0003] In the existing hot air dryer, new metal materials to be dried are hung in the drying chamber of the hot air dryer by means of hooks, and then the drying chamber is closed and the hot air blower is turned on, so that the hot air blower introduces external air for heating and blows hot air to the new metal materials in the drying chamber to dry the new metal materials. However, in actual use, the installation position of the hot air blower is fixed, resulting in a fixed blowing angle of the hot air blower. As a result, when the hot air blower is drying the new metal materials, the new metal materials close to the hot air blower and the new metal materials far away from the hot air blower can receive different amounts of hot air, which results in a certain amount of time required for complete drying of the new metal materials in the drying chamber, and poor drying efficiency for the new metal materials.
