The main working principle of an industrial oven: The oven is constructed of a carbon steel plate of a certain thickness, with fiberglass filling between the two. It operates in conjunction with a temperature controller, heating elements, and a well-designed air circulation system. Instruments and temperature sensors monitor the internal temperature of the industrial oven, which is then controlled by the temperature control system. Compared to conventional heating methods, the industrial oven's air circulation heating method utilizes a large-diameter impeller, which provides better air flow and accelerates the drying of materials within the oven. The industrial oven's air circulation system consists of a blower motor, a large-diameter impeller, and heating elements. The blower motor drives the impeller to deliver cold air, which is then heated by the heating elements and evenly distributed through the air ducts to every corner of the oven. The industrial oven's air circulation system helps maintain air temperature uniformity. The temperature fluctuates during the opening and closing of the oven door and the transfer of materials. The uniformity of the air circulation system ensures that the operating temperature is restored to its normal value as quickly as possible, thus minimizing temperature fluctuations. The inner chamber features perforated side panels on both sides, allowing hot air to flow out through the holes. After passing through the inner chamber, it is drawn back into the inner air duct by the impeller, where it is continuously heated and circulated, ultimately reaching a constant temperature.
Industrial ovens are a versatile drying device widely used in agriculture, industry, hardware, electronics, and plastics factories, as well as in areas where large areas or large quantities of products need to be baked, such as digital tubes, LED diodes, SMDs, SMD silicone rubber, AB glue, motors, printing, electroplating, paint, and chemical industries. These ovens are used for drying, dehydrating, preheating, tempering, aging, and shaping. They are widely used in industrial production. However, they are not suitable for highly volatile, flammable, or explosive materials to avoid explosions.
The current market mainly categorizes these ovens into horizontal circulation and vertical circulation. Users can choose the right oven based on the items being baked and the oven's volume.
