[0002] A bread baking tunnel oven is a continuous baking equipment designed specifically for bread products. It features a long, narrow tunnel design and is equipped with electric heating elements or direct-fired burners. Heat is transferred to the bread to be baked through a hot air circulation system.
[0003] Common bread baking tunnel ovens often use insulation cotton on both sides of the conveyor. However, this insulation cotton is easily damaged after long-term use and is inconvenient to replace. Moreover, the heat preservation and heat storage performance of the insulation cotton will decrease significantly after long-term use, affecting the taste of the baked bread. This paper proposes a side stone plate installation structure for bread baking tunnel ovens. Utility Model Content

[0006] A side stone plate mounting structure for a bread baking tunnel oven includes a baking tunnel oven body. The baking tunnel oven body is fixedly connected to the inner walls on both sides of the conveyor with a first mounting bracket and a second mounting bracket. The first mounting bracket and the second mounting bracket are connected and fixed to the inner walls of the baking tunnel oven body with a number of screws. A number of heat-insulating stone plates are inserted between the first mounting bracket and the second mounting bracket on the same side.
[0007] Preferably, both the first mounting bracket and the second mounting bracket are made of aluminum alloy.
[0008] Preferably, the material of the heat-insulating stone slab is marble.
[0009] Preferably, both the first mounting bracket and the second mounting bracket have arc-shaped protrusions on the vertical sidewalls near the upper and lower ends of the insulation stone slab, and both arc-shaped protrusions abut and press against the sidewalls of the insulation stone slab.
[0010] Preferably, the first mounting bracket and the second mounting bracket are provided with blocky rectangular protrusions on their opposite sidewalls, and the upper and lower ends of the heat-insulating stone slab are provided with rectangular slots that are connected front and back, and the two blocky rectangular protrusions are respectively inserted into the two rectangular slots.
[0011] Preferably, the arc-shaped protrusion and the blocky rectangular protrusion are integrally cast with the first mounting bracket, and the arc-shaped protrusion and the blocky rectangular protrusion are integrally cast with the second mounting bracket.
[0012] Compared with the prior art, the advantages of this utility model are as follows:
[0013] 1. By fixing the first and second mounting brackets to the inner walls on both sides of the conveyor of the baking tunnel oven body, the heat-insulating stone plate is inserted between the first and second mounting brackets, so that the blocky rectangular protrusion is inserted into the rectangular slot, and the arc-shaped protrusion is pressed against the heat-insulating stone plate, which effectively positions the heat-insulating stone plate. The structure is simple and easy to disassemble and replace.
[0014] 2.
