The tunnel furnace is a large baking equipment that provides continuous baked goods. Equipped with production lines to achieve high production efficiency, energy saving manpower, and stable baking quality. The emergence of industrial tunnel furnaces meets the drying needs of various industries, and industrial tunnel furnaces are therefore widely used.
The tunnel furnace is one of the important equipments in the coating production line, and its temperature uniformity is an important indicator to ensure the quality of the coating. The heating methods of the oven are: radiation, hot air circulation and radiation + hot air circulation, etc. According to the production program, the single chamber and the pass type can be divided, and the equipment forms are straight-through type and bridge type. Tunnel furnace is a tunnel-type mechanical equipment that completes food baking through heat conduction, convection and radiation. The oven body is generally long, and the Zui is 10 meters small and grows to 60 to 80 meters. The baking chamber is a narrow tunnel with a width of generally 80 cm to 140 cm. There is a continuously operating conveyor system inside the tunnel. The structure of the tunnel furnace is generally fully enclosed, and is mainly composed of valves, tunnels, pipes, heaters and the like. The tunnel furnace can be used for baking food, bread, cakes, moon cakes, chicken, duck, meat, fish, bread, cakes, biscuits, snacks, egg yolk pies, moon cakes, etc. in food factories, bakeries and self-employed households. It can also be used for dry food use.
The heating methods of the tunnel furnace are divided into four types: electric hot air converter, gas hot air converter, diesel hot air converter, and electric firewood dual-purpose hot air converter. Different products have different requirements on baking time, and the hot air converter can drive variable frequency speed regulation and stepless speed change. The baked product is heated inside and outside at the same time, the temperature difference between inside and outside is small, no deformation, no discoloration, and stable quality. The baking speed is fast and the efficiency is high, which can save about 6-10 times of time and greatly shorten the production and shipping cycle. Local heating, less energy waste, saving more than 30%. Due to the large amount of energy transmission per unit area, the volume is small, the space is saved, and the construction cost is saved. Can be used in connection with the production line, synchronous control, reducing defects. The temperature can be controlled in stages, which can adapt to product requirements and has high elasticity. Control the air suction device, less solvent residue, no danger, explosion-proof, environmental protection. The external temperature of the casing is close to the ambient temperature, and the working environment is comfortable, reducing energy waste. The product is in advance, no need to stand after baking, shorten working hours and reduce pollution. Adopting stepless constant temperature control system, the product quality is stable. The Sisida tunnel furnace (food processing) and the tunnel furnace equipment pay special attention to its low energy consumption, energy saving, uniform speed and durability, and emphasize safety design and aesthetic design.
