Introduction to Infrared Tunnel Furnace
Infrared tunnel furnace is an industrial equipment that utilizes infrared radiation for heating, and it is widely applied in various industries that require processes such as heating, drying, and curing. The following is a detailed introduction to the infrared tunnel furnace:
Tunnel Furnace Body: It is usually made of metal sheets, possessing good sealing and heat insulation properties to reduce heat loss. The interior of the furnace body is divided into a tunnel-shaped space, and materials are moved through the tunnel by a conveying device.
Infrared Heating System: This is the core part of the tunnel furnace, consisting of multiple infrared heating elements, such as infrared lamps and infrared heating panels. These heating elements are distributed on the top and both sides of the tunnel furnace in a certain arrangement so as to uniformly radiate infrared rays to the materials.
Conveying Device: It is used to transport materials through the tunnel furnace. Common conveying methods include mesh belt conveying, chain conveying, and roller conveying. The speed of the conveying device can be adjusted according to the process requirements to ensure that the materials are fully heated inside the furnace.
Temperature Control System: Equipped with temperature sensors and controllers, it monitors and controls the temperature inside the furnace in real time. Operators can set appropriate temperature parameters according to different materials and process requirements. The temperature control system will automatically adjust the power of the infrared heating elements to keep the temperature inside the furnace within the set range.
Ventilation System: It includes air inlets and outlets and is used to regulate the air circulation inside the furnace. The ventilation system can help discharge the waste gas and moisture generated during the heating of materials, and at the same time introduce fresh air to ensure the freshness and dryness of the air inside the furnace, which is beneficial to improving the heating effect and product quality.
The working principle of the infrared tunnel furnace is based on the thermal effect of infrared rays. Infrared rays are electromagnetic waves with strong penetrating ability and thermal effect. When infrared rays irradiate the surface of materials, a part of the infrared rays are absorbed by the materials and converted into heat energy, which intensifies the molecular movement of the materials, thus achieving the purpose of heating. Compared with traditional heating methods, infrared heating has the advantages of fast heating speed, high thermal efficiency, uniform heating, and energy saving.
High Efficiency and Energy Saving: Infrared heating can directly act on materials, reducing the heat transfer process of intermediate media. With little heat loss, it has a high thermal efficiency and can save energy.
Uniform Heating: By reasonably arranging infrared heating elements, the distribution of infrared radiation inside the furnace can be made more uniform, thus ensuring that materials are heated uniformly during the heating process and improving the consistency of product quality.
Quick Temperature Rise: Infrared heating elements can quickly reach the working temperature with a fast start-up speed, enabling quick heating of materials and improving production efficiency.
Environmentally Friendly and Clean: The infrared heating process does not produce harmful substances, causing no pollution to the environment. Meanwhile, it will not pollute the materials either, meeting the environmental protection requirements of modern industry.
Easy to Control: The temperature control system can accurately control the temperature inside the furnace. Operators can flexibly adjust parameters such as temperature and conveying speed according to different process requirements, facilitating the realization of automated production.
Food Industry: It is used for baking, drying, and sterilization processes of food, such as the processing of bread, biscuits, and potato chips.
Pharmaceutical Industry: It can be used for drying, curing, and sterilization of pharmaceuticals to ensure the quality and stability of drugs.
Electronic Industry: It is used for drying, curing, and welding of electronic components. For example, it is applied to the coating drying of circuit boards and the encapsulation curing of electronic devices.
Coating Industry: It is used for drying and curing of surface coatings of automobiles, furniture, machinery, etc., which can improve the adhesion and glossiness of coatings.
Printing Industry: It enables the quick drying of ink on printed materials, improving printing efficiency and quality and reducing ink penetration and smudging.
