Someone asked electric heating: What is the working principle, classification and advantages of hot air circulation oven? Today, we will introduce the hot air circulating oven. First of all, let's introduce the working principle of hot air circulation oven.
First, the definition and principle of hot air circulation oven
Generally, hot air circulating ovens all have heating pipes, and ovens with circulating fans can all be called hot air circulating ovens, because in the final analysis, hot air circulates in them, regardless of the structure of the oven and whether the wind direction is horizontal or vertical.
The air circulation system of hot air circulation oven adopts fan circulation air supply mode, and the air circulation is uniform and efficient. The wind source is driven by the circulating air supply motor to drive the wind wheel to pass through the heater, so that the hot air is sent out, then sent to the inner cavity of the oven through the air duct, and then the used air is sucked into the air duct to become the wind source for recycling and heating. Ensure the uniformity of indoor temperature.
Second, the advantages of hot air circulation oven
1. Ovens are generally made of carbon steel and stainless steel, with a thickness of 2.0MM, a design temperature of 300 degrees and a control accuracy of 65438 0 degrees. The heating element is a stainless steel finned heating tube.
2. The advantages of the oven are: (1) strong durability, because the heating pipe is sealed in the box, the contact surface with the outside air is small, and it is not easy to be oxidized and corroded.
⑵ Internal circulation, the dried objects are heated evenly.
⑶ Electrical control is safe, accurate and reliable, with reasonable structure, large effective working area, complete functions, simple operation, convenient maintenance and adjustment, low noise, high reliability, low cost, low energy consumption and high production efficiency.
Three, hot air circulation oven classification
1. Ovens are divided into constant temperature oven, experimental oven, hot air circulation oven, covered electrode oven, high temperature oven, vacuum oven, trolley oven and tunnel oven.
2. The oven is generally composed of an inner cavity, a heating element, a control box, a fan, an insulation layer and a shell.
3. The circulation mode of hot air circulation oven is divided into horizontal air supply and vertical air supply.
4. Workplace: food drying, chemical raw materials, medical devices, laboratory research, wood and building materials.
