In view of the problems such as high labor intensity, low processing efficiency and great potential danger during the baking process of Xinjiang Naan, an electric tunnel-type Naan baking stove was designed. By the COMSOL software, the thermal simulation of tunnel-type Naan baking stove drawn by SolidWorks was made, so as to find out the heat distribution, heat source loss position and the Naan sizes suitable for processing in Naan baking stoves. In the workshop, a baking experiment was made on the prototype in order to realize the baking of Naan. The simulation results show that the heat dissipation at the inlet and outlet of the baking oven is serious, and the large distance between the heating rods is not suitable for heating Naan. The test results show that the baking stove has good baking effect and stable baking performance under the test conditions of determining the transmission speed of 6m/s and the heating tube temperature of 260 °C by adjusting various horizontal factors and parameters, which can achieve the expected design objectives and has certain value for popularization and application.
