First, the working principle of: 

 LXG hot air circulation oven with steam or electricity as a heat source, heat using centrifugal fan means to force heated air heat exchanger, hot air laminar flow of materials through the baking tray and heat and mass transfer. Fresh air inlet into the oven from the supplement, from Moisture discharge port, continue to add fresh air and exhaust hot and humid air continuously. Way to maintain proper relative humidity inside the oven. The oven is the most important feature of the series most of the circulating hot air in the box. Thus increasing the heat, saving energy. It is the role of using forced ventilation, reducing the temperature difference from top to bottom. I produced the oven, located partakers wind device, the user can adjust the blades before use, so that the upper and lower temperature at its best. LXG Series oven without automatic control, the use of 4-72 type centrifugal fan.
