Description

Technical Field

[0001] This utility model relates to the field of oven technology, specifically a contact oven. Background Technology

[0002] Traditional drying ovens are processing equipment that place the workpieces to be dried inside their chambers and subject them to high temperature, negative pressure, or high-temperature airflow conditions to achieve the drying operation. Vacuum drying ovens, in particular, typically heat the oven walls or the workpieces to be dried using hot air, then evacuate the chamber to a negative pressure vacuum. This allows the moisture in the workpieces to evaporate rapidly under high temperature and low pressure, and a vacuum pump removes the evaporated moisture, thus achieving the drying purpose. However, traditional processes rely on heat radiation and air conduction for heating, i.e., indirect contact heating of the workpieces. This results in high energy consumption, long drying cycles, and insufficient drying of the workpieces. Utility Model Content
