[0002] Drying ovens are mainly used for constant temperature drying, baking, sterilization and heat treatment of items. They maintain a constant temperature inside the oven by heating, thereby accelerating the evaporation of moisture or achieving the drying and curing of materials.

[0003] Most existing constant temperature drying ovens use a combination of electric heating wire heating and hot air circulation to achieve constant temperature heating. Typically, fans are installed on both sides of the oven, with an electric heating wire installed at the air inlet on one side. When the fan is running, it blows the heated air evenly into the oven, achieving stable and uniform temperature distribution. However, the internal material racks of these drying ovens are usually fixed trays, making it inconvenient for users to load and unload materials. This is especially true when changing material types or cleaning the internal space, as removing or adjusting the material racks is difficult, affecting overall efficiency and flexibility.
