Background

In the frying and roasting machine disclosed in the related art, the heating manner of the upper and lower roasting trays is an indirect electric heating manner, that is, the heating pipe converts electric energy into heat energy and then transmits the heat energy to the roasting tray, or the heating pipe is fixed to the disk-shaped heating plate, so that the heat energy of the heating pipe is homogenized through the heating plate and then transmitted to the roasting tray through the heating plate. In this way, the upper and lower baking trays of the frying and roasting machine are required to be in direct contact with the surfaces of the food materials to finish double-sided frying and roasting, and the food materials are not crisp enough due to the pressure of the upper baking trays. Therefore, in order to improve the taste of the food materials, some frying and baking machines adopt far infrared heating devices as photo-thermal elements, and are directly fried, baked and cured in a far infrared light radiation mode.

However, in the frying and roasting machine using the far infrared heating device, since the far infrared light has a good penetrating effect, when the upper and lower roasting tray assemblies are buckled for use, the upper surface of the food material is roasted by the far infrared light, and the lower surface of the food material is roasted by the lower roasting tray, so that the roasting and frying of the food material are both considered, and the two surfaces of the food material are uniformly colored, which is a problem to be solved in the far infrared frying and roasting machine.
