The industrial double-door oven is a heating device widely used in industrial production, mainly used for baking, drying, curing and other treatments of various industrial products. The following is a detailed introduction to it:
Box Body: It is usually made of high-quality cold-rolled steel plates or stainless steel plates, which have good strength and corrosion resistance. The surface of the box body is generally spray-coated, which can not only increase the aesthetic appearance but also play a role in rust prevention and heat insulation.
Double-door Design: Equipped with two doors, it is convenient for the loading and unloading of materials and operation. The doors have good sealing performance. High-temperature-resistant sealing strips are used, which can effectively prevent heat loss and improve the thermal efficiency of the oven. Some oven doors are also designed with observation windows, which facilitate operators to observe the working conditions inside the oven without opening the doors.
Heating System: It adopts the electric heating method, and common heating elements include electric heating tubes or heating wires. These heating elements are evenly distributed inside the oven and can provide stable and uniform heat. Through the temperature control system, the temperature inside the oven can be precisely adjusted to meet the requirements of different processes.
Insulation Layer: Insulation materials such as rock wool and glass wool are filled between the inner and outer parts of the box body. The function of the insulation layer is to reduce the transfer of heat to the outside, lower energy consumption, and at the same time prevent the surface temperature of the oven from being too high to ensure the safety of operators.
Circulation System: It includes a hot air circulation system and an exhaust gas discharge system. The hot air circulation system makes the hot air inside the oven continuously circulate through the fan to ensure temperature uniformity; the exhaust gas discharge system is used to discharge the exhaust gas and water vapor generated during the baking process, keep the air inside the oven fresh, and is conducive to improving product quality.
The working principle of the industrial double-door oven is to use the electric heating elements to convert electrical energy into heat energy, and increase the temperature of the air inside the oven through heat transfer. The materials to be baked are placed on the shelves or conveyor belts inside the oven. In a high-temperature environment, the moisture or solvent in the materials gradually evaporates, so as to achieve the purposes of drying, curing, etc. The hot air circulation system makes the hot air continuously flow inside the oven, which not only improves the temperature uniformity but also accelerates the evaporation speed of the moisture on the surface of the materials and improves the drying efficiency.
Electronics Industry: It is used for the aging test of electronic components, the drying of circuit boards, the baking paint of electronic device casings, etc. For example, in the production process of circuit boards, the soldered circuit boards need to be put into the oven for drying to remove the residue of soldering flux and moisture, and improve the performance and reliability of the circuit boards.
Hardware and Machinery Industry: It is used for the heat treatment of hardware parts, the drying after electroplating, and the paint drying of mechanical components, etc. For example, after electroplating, hardware products need to be quickly dried through the oven to prevent the electroplated layer from oxidizing and peeling off.
Plastic and Rubber Industry: It is used for the drying of plastic pellets, the vulcanization of rubber products and other processes. Plastic pellets usually need to be dried before processing to remove moisture and avoid the generation of bubbles or defects during the molding process.
Food Industry: Although the industrial double-door oven is mainly used for industrial production, in some food processing enterprises, it is also used for the batch baking of foods such as bread and pastries. However, the ovens used for food processing have higher requirements in terms of hygiene standards and material selection.
Precise Temperature Control: An advanced temperature control system is adopted, which can precisely control the temperature inside the oven. The temperature control accuracy can generally reach ±1°C or even higher. This is very important for ensuring the consistency of product quality, especially for some processes that are sensitive to temperature.
Good Temperature Uniformity: Through the reasonable layout of heating elements and the hot air circulation system, the temperature difference between various parts inside the oven is small, generally within ±5°C. The uniform temperature distribution enables the materials to be heated evenly during the baking process, avoiding the phenomenon of local overheating or underheating, and thus improving product quality.
High Production Efficiency: The double-door design facilitates the quick loading and unloading of materials. The oven has a fast heating speed, can reach the set temperature in a short time, and can operate continuously to meet the needs of large-scale industrial production.
Simple Operation: It is equipped with an operation panel, and operators can easily set parameters such as temperature and time through the buttons or touch screen on the panel. Some ovens also have an automatic alarm function. When the oven malfunctions or the temperature is abnormal, an alarm sound will be issued to remind the operators to deal with it in time.
Safe and Reliable: It has a variety of safety protection devices, such as overheat protection, leakage protection, short-circuit protection, etc., which can effectively prevent safety accidents during the operation of the oven and ensure the safety of operators and equipment.
