This material has good thermal insulation performance, can effectively reduce heat loss, improve baking efficiency, and reduce energy consumption. A PID temperature controller 1 is installed on the back of the baking chamber, which can accurately control and adjust the temperature in the baking chamber, ensure the temperature stability and uniformity during the baking process, and thus improve the baking quality. A plurality of U-shaped resistance bands 3 are evenly arranged on the inner walls of both sides of the baking chamber.
