How to buy a tunnel type hot air circulation oven

Ovens are necessary equipment in the processing of many products, and tunnel hot air circulation ovens are very popular among ovens due to their excellent characteristics. A suitable tunnel Hot air circulation oven helps to save costs, reduce energy consumption, and produce high-quality products, and the correct evaluation of oven technology and cost is of great significance for choosing the appropriate oven technology. So how to choose a suitable tunnel hot air circulation oven?

1. The size of the oven: The size of the oven generally depends on the quantity and size of the materials in the oven. During the constant temperature drying process, the quantity and arrangement of materials in the oven affect the temperature uniformity of the drying chamber. When the temperature uniformity is high, it is recommended to reduce the number of samples or choose a large oven to ensure hot air convection in the drying chamber.

2. Temperature range and operating temperature: Different types of ovens have different adjustable oven temperatures. When choosing, it is necessary to ensure that the operating temperature is lower than the maximum temperature to prevent the body from being overloaded and damaged.

3. Temperature uniformity: The temperature uniformity of the tunnel-type hot air circulation oven is an important performance index, which refers to the temperature difference at each point in the drying room during the constant temperature stage of the oven. A large temperature difference will result in uneven heating of the sample at different locations.

4. Heating power: The normal heating rate of the hot blast stove is generally 10/min. When heating at low temperature, the temperature rises quickly, the temperature rises slowly at high temperature, the temperature rises rapidly in summer, and the temperature rises slowly in winter. Increasing the heating power can increase the heating speed. But the heating power of the oven increases, and the temperature overshoot will increase at a constant temperature.

5. Other settings, different industries have different requirements for the oven, such as multi-stage heating, heat preservation control or heating rate control.

The choice of tunnel type hot air circulation oven should be selected according to the required performance index, such as the required size, temperature range, how many degrees of oven are needed to dry, and the heating power, as well as some other performance comparisons, etc. Only in this way can you choose a tunnel-type hot air circulation oven that you are satisfied with.
