Vacuum Hot Air Oven High Temperature Hot Air Vacuum Oven Principle of Hot Air Circulation Vacuum Dryer
Vacuum Hot Air Oven Working Principle: During the circulation stage, the fan generates a strong airflow, uniformly distributing the hot air throughout the oven interior, ensuring thorough contact between the hot air and the item's surface to accelerate heat conduction. During the moisture removal stage, the surface moisture of the items inside the oven is evaporated by the hot air, and the moisture is expelled from the oven through the exhaust port.
Vacuum Hot Air Oven High Temperature Hot Air Vacuum Oven Hot Air Circulation Vacuum Dryer
The air source is driven by a circulating fan motor, which rotates the fan wheel through an electric heater to expel hot air. The hot air then circulates through the ducts within the oven chamber, and the used air is drawn back into the duct to become the air source for another cycle, ensuring even heating and maintaining consistent indoor temperatures.

The steps for using the vacuum hot air oven are as follows:
Place the to-be-dried samples in the drying chamber.
Close the drying chamber door and ensure it seals properly.
Turn on the vacuum pump switch on the drying chamber and start the vacuum process.
4 When the vacuum level reaches the desired value, turn off the vacuum pump switch, allowing the drying chamber to return to atmospheric pressure.
