Hot air circulation ovens generally feature heating elements and circulation fans. Any oven with these components can be termed a hot air circulation oven, as regardless of its structural design or whether airflow is horizontal or vertical, the fundamental principle remains the circulation of hot air within the chamber. Below is a brief overview of its primary advantages and key considerations during operation.
I. Key Advantages of Hot Air Circulation Ovens
1. Conveying systems primarily utilize stainless steel or stainless steel mesh belts, allowing adjustable operating speeds to suit diverse products and requirements.
2. Heating elements employ high-quality quartz glass tubes or far-infrared directional radiators, featuring high radiation efficiency, low energy consumption, rapid heating, and minimal thermal shock.
3. Except for the frame, the entire oven is constructed from stainless steel. Insulation utilizes aluminum silicate fiber, ensuring excellent thermal retention.
4. Equipped with electrical components including a motor, speed regulator, voltmeter, ammeter, and digital temperature controller to guarantee stable operation.
II. What precautions should be observed when using a hot air circulation oven?
1. Place the hot air circulation oven on a dry indoor floor or workbench surface.
2. Install a dedicated knife switch or circuit breaker in the power supply circuit for this oven. Use a grounding wire with a cross-sectional area twice that of the power supply cable.
3. Before energizing, inspect the oven's electrical components and check for open circuits or leakage.
