Electric blast drying box - Huaqiang Electronic Network

The electric blast drying oven is a versatile and essential piece of equipment used in laboratories, industrial settings, and various scientific applications. It consists of a housing unit, an electric heating element, a temperature controller, a fan, a convection air duct system, an air inlet and outlet duct, and an adjustable air outlet mechanism. This design ensures even heat distribution and efficient drying processes.

Operating procedures for the electric blast drying oven are straightforward but require careful attention to detail:

1. First, set the desired temperature on the digital display controller. Then, turn on the power supply and activate the heating switch. Adjust the temperature control knob to the "high temperature" position. At this point, the internal temperature will begin to rise, and the green indicator light will illuminate, displaying the current temperature on the screen.
2. Once the temperature reaches the target value, the red and green indicator lights will alternate, indicating that the oven has reached a stable constant temperature. At this stage, adjust the temperature control knob to the "low temperature" setting, and turn off one set of heating elements to reduce power consumption and improve temperature stability.
3. After reaching the required temperature, the oven can be used for testing or sample drying. Avoid opening the door frequently during this time to maintain a consistent internal environment.

Important notes when using the electric blast drying oven:

• Install the oven in a dry, stable location with ambient temperatures not exceeding 40°C and relative humidity below 85%.
• The interior is coated with high-temperature resistant paint to prevent corrosion. Avoid damaging this layer to maintain the oven's integrity.
• If the oven lacks an over-temperature protection system, a dedicated operator should monitor the temperature continuously to prevent potential hazards.
• The maximum load capacity of each shelf is 15 kg. Ensure samples are evenly distributed and not placed directly on the lower plate (heat sink) to avoid uneven heating.

Temperature overshoot is a common issue when starting up the oven, where the internal temperature temporarily exceeds the set point by more than 5°C before stabilizing. While it cannot be completely eliminated, modern control systems have reduced this effect to within 2–3°C. For users with older models, two methods can help minimize overshoot: the empty box preheating method and the two-stage heating approach. Both methods aim to achieve a more stable and controlled drying process.
