Hot air circulation oven includes four parts: main chamber, recycle fan, heating system and control system. Materials will be put on the drying tray and be pushed into the drying chamber by trolley. Cold air will be heated to a certain temperature via heating device, under the working of recirculation fan, hot air recycles in chamber, thus drying purpose could be reached by fully contacting between hot air and material. During drying, humid air will be exhausted gradually through damp outlet. Meanwhile, fresh air will be supplemented. Temperature inside oven could be kept evenly by adjusting the angle of shutter, thus make sure the drying uniformity of material with equal rate. The hot air circulation oven air circulation system adopts a fan circulation air supply mode, and the air circulation is uniform and efficient. The wind source is driven by a circulating air supply motor (using a non-contact switch) to drive the wind wheel through the heater, and the hot air is sent out, and then the air is taken into the air chamber through the air passage, and then the used air is sucked into the air passage to be recirculated as a wind source. This ensures room temperature uniformity. When the temperature value oscillates due to the operation of the switch door, the air circulation system quickly returns to the operating state until the set temperature value is reached. Features -Most of hot air is circled inside the oven. The hot efficiency is high. The energy source can be saved. -Batch drying with different capacity is available. -The machine has low noise and stable operation. The temperature can be controlled automatically. The installation and maintenance are very convenient. As one of the leading dryer manufacturers in China, we are dedicated to designing and manufacturing all kinds of hot air circulation oven.
