[0002] The bread baking tunnel oven is a continuous baking equipment designed specifically for bread products. It is equipped with temperature and humidity sensors and an automated control system, which can accurately adjust baking parameters to ensure product consistency. The bread baking tunnel oven uses chain plates, steel belts or mesh belts to transport bread from the feeding area to the heating area, and then transfers it to the cooling area through the discharge port, realizing automated operation.

[0003] In practical use, existing bread baking tunnel ovens often use a single insulation board for the lower heating element, which results in poor heat preservation and energy storage performance, and the insulation board is inconvenient to replace. This paper proposes a high-efficiency insulation structure for bread baking tunnel ovens to solve the above problems. Utility Model Content

The inner walls of the left and right sides of the tunnel oven body facing the conveyor are provided with concave mounting brackets. The upper and lower ends of the two concave mounting brackets near the inner wall of the tunnel oven body are fixedly connected to connecting plates. Several positioning screws are provided through the two connecting plates. The positioning screws are fixedly connected to the inner wall of the tunnel oven body. Multiple sets of heat-insulating stone plates and heat insulation plates are inserted into the two concave mounting brackets.

[0007] Preferably, the heat-insulating stone slab is made of marble, and the heat insulation board is made of ceramic fiber.

[0008] Preferably, an adhesive layer is provided between the heat-insulating stone slab and the heat insulation board, and the adhesive layer is a stone adhesive.

[0009] Preferably, the upper and lower ends of the heat-insulating stone slab are provided with strip grooves that are connected front and back, and the vertical protrusions on both sides of the concave mounting bracket are respectively inserted into the two strip grooves.

[0010] Preferably, the inner sidewall at the center of the concave mounting bracket is provided with a strip-shaped rectangular protrusion, and the right sidewall of the heat insulation plate opposite to the strip-shaped rectangular protrusion is provided with a strip-shaped rectangular slot that is connected front and back, and the strip-shaped rectangular protrusion is inserted into the strip-shaped rectangular slot.

[0011] Preferably, the connecting plate and the strip-shaped rectangular protrusion are integrally cast with the concave mounting bracket.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By bonding and fixing multiple sets of heat-insulating stone slabs and heat insulation boards with an adhesive layer, and inserting multiple sets of heat-insulating stone slabs and heat insulation boards into a concave mounting frame, the vertical protrusion of the concave mounting frame is inserted into the strip-shaped slot on the heat-insulating stone slab, and the strip-shaped rectangular protrusion in the concave mounting frame is inserted into the strip-shaped rectangular slot on the heat insulation board. This allows for quick and easy positioning of multiple sets of heat-insulating stone slabs and heat insulation boards in the concave mounting frame. The structure is simple and easy to replace.
