1、 The implementation logic of rapid heating

Problem introductionWhy is the heating rate of traditional drying ovens slower? How to achieve rapid heating through technological improvements?

Traditional drying ovens rely on natural convection to transfer heat, and their thermal efficiency is limited by the air flow velocity and heat transfer path. The constant temperature electric blast drying oven breaks through this limitation through the following design:

1. Forced hot air circulation systemBuilt in high-temperature resistant fan and optimized air duct design quickly distribute the heat generated by the heating element to the entire cavity, reducing local temperature gradients.

2. Efficient heating element layoutUsing multi zone distributed electric heating tubes or far-infrared heaters, combined with PID temperature control algorithm, to ensure uniform heat release and rapid response to temperature changes.

3. Low thermal inertia materialThe box is made of lightweight and high thermal conductivity materials (such as special alloys or composite insulation layers) to shorten the thermal response time of the heating system.

For example, in the food industry, a certain model of equipment can raise the chamber temperature from room temperature to 180 ℃ within 30 minutes, significantly better than the 1-hour heating time of traditional equipment.

2、 Technical points of constant temperature control

Problem introductionHow to achieve temperature stability at ± 0.5 ℃ level? What factors may affect temperature control accuracy?

Constant temperature control relies on the synergy of three technologies:

• Sensor feedbackHigh precision platinum resistance (PT100) real-time monitoring of chamber temperature, with a sampling frequency of up to once per second.

• PID intelligent regulationDynamically adjust heating power through proportional integral derivative algorithm to avoid temperature overshoot or hysteresis.

• Air duct optimizationMulti layer baffle design ensures uniform airflow coverage of the sample area, reducing local temperature differences caused by air entrapment.

4、 Selection and usage suggestions

1. Selection of core parameters：

• temperature rangeConventional laboratory requirements are mostly room temperature+10 ℃~250 ℃, and high-temperature industrial scenarios need to be extended to above 300 ℃.

Problem introductionHow to ensure operational safety and reduce energy consumption during high-temperature operation?

1. Multiple security protections：

• Overtemperature alarm and power-off protectionWhen the temperature exceeds the set threshold, the system automatically cuts off the heating power to prevent damage to the sample or equipment.

• Pressure relief mechanismWhen the air pressure inside the box is abnormal, the pressure relief plate will automatically open to avoid accidents caused by pressure accumulation.

• Anti scald designThe shell is made of insulation material, and the door seal structure is optimized to reduce the risk of external contact.

2. Energy efficiency improvement strategy：

• heat recoveryBy designing the return air chamber, some of the waste heat is reintroduced into the heating system to reduce overall energy consumption.
