working principle
When the power supply of the drying oven is turned on, the electric motor runs simultaneously, directly discharging the heat generated by the electric heater located at the bottom of the oven through the air duct, and then sucking it into the fan after drying the items in the working chamber, thus continuously circulating and achieving uniform temperature in the working chamber.
Intelligent temperature controller with automatic wind speed adjustment function. During the heating process, the motor runs at high speed and automatically adjusts to low speed operation when the temperature approaches a constant level, thereby reducing usage problems caused by excessive wind speed. Users can also cancel this function through simple operations. The air door regulator can adjust the amount of air entering and leaving the box by opening the air door adjustment knob.

Structural Introduction
1. The outer shell of the box is made of high-quality steel plate surface baked paint, and the studio uses mirror stainless steel plate SUS304 material;
2. The middle layer is filled with ultra-fine glass wool for insulation;
3. The box door adopts double-layer tempered glass as an observation window, which can clearly observe the items inside the box;
4. A heat-resistant silicone rubber sealing ring is installed at the connection between the studio and the box door to ensure sealing between the studio and the box door;
5. The power switch and temperature controller of the drying oven are concentrated on the front of the box;
The heating and constant temperature system inside the box mainly consists of a high-quality imported electric motor equipped with a centrifugal impeller, an electric heater, a suitable air duct structure, and a temperature controller.
control system
1. Temperature sensor: Pt100 platinum resistor;
2. Control device: The equipment adopts the Shanghai University of Technology series control system, with digital LED display and internal PID operation controller function;
3. System setting resolution: 0.1 ℃;
4. By setting the time through the instrument, the heating can be automatically cut off; To prevent temperature overshoot.

Usage Notes
After connecting the power supply, you can turn on two sets of heating switches, and then set the temperature you need by pressing the buttons on the control instrument. The indicator light is on, and at the same time, the blower switch can be turned on to make the blower work.

When the temperature reaches the desired level, the indicator light will turn off. At the beginning of constant temperature, there may be a continued increase in temperature, which is due to the influence of residual heat. This phenomenon will tend to stabilize in about half an hour. During the constant temperature process, automatic temperature control is achieved through the use of an internal temperature controller within the box, eliminating the need for manual management.

3. When maintaining a constant temperature, one set of heating switches can be turned off, leaving only one set of electric heaters working to avoid excessive power and affecting the sensitivity of the constant temperature.

4. The box should be placed at an indoor level.

5. An iron shell knife switch should be installed in the power supply line for this box, and the outer shell should be grounded.

Before powering on, please check the electrical performance of this box and pay attention to whether there is any open circuit or leakage.

7. When everything is ready, the test sample can be placed in. Close the box door and open the top exhaust valve at the same time. At this time, the power can be connected to start working.

8. Do not remove the side door arbitrarily, disturb or change the circuit. Only when the box malfunctions, the side door can be removed and checked one by one according to the circuit.

9. This box is a non explosion proof drying box, so it contains flammable and volatile substances. Do not put it inside the drying box to avoid accidents.

10. Each drying oven is equipped with two sample shelves. The average load per shelf is 15 kilograms. When placing the test sample, do not place it too tightly or overload it to avoid affecting the convection of hot air. At the same time, the test sample cannot be placed on the bottom heat dissipation plate of the studio to prevent overheating and damage to the test sample.
