Description

Technical Field

[0001] This utility model relates to the field of pastry processing technology, and in particular to a tunnel oven for pastry processing. Background Technology

[0002] A tunnel oven is a tunnel-shaped mechanical device that bakes food using heat conduction, convection, and radiation. The oven body is typically long, with the baking chamber being a narrow tunnel containing a continuously operating conveyor system. During baking, the food moves relative to the heating elements or direct-fired burners via conveyor chains, steel belts, or mesh belts. This ensures uniform baking and transport. These ovens can operate continuously, offering high production efficiency, labor savings, and consistent baking quality. Tunnel ovens are primarily used in industrialized food production, characterized by large-scale continuous or intermittent baking.

[0003] The temperature control effect of the internal electric heating elements in the existing tunnel ovens for pastry processing is poor. As a result, the temperature of the pastries cannot be reduced to a certain value when they come out of the oven, which may lead to burns for the staff when sorting them.

[0004] To address these issues, we propose a tunnel oven for pastry processing. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a tunnel oven for pastry processing, comprising:

[0023] The tunnel oven body 1 and the conveying device 2 work together. Both the tunnel oven body 1 and the conveying device 2 are existing mature technologies that can bake and convey pastries. Multiple support bases are fixedly connected to the conveying device 2. The multiple support bases are made of non-slip material to ensure the stable placement of the whole device. The end of the conveying device 2 away from the tunnel oven body 1 is connected to a cooling box 3 through a disassembly assembly. The cooling box 3 is coated with a protective coating that adheres to the cooling box 3, thereby improving the service life of the cooling box 3. The cooling assembly includes an intermediate transmission column 4 rotatably connected to the outer wall of the end of the cooling box 3 away from the conveying device 2. An intermediate transmission gear 5 is fixedly connected to the intermediate transmission column 4, so that when the intermediate transmission column 4 rotates, it can drive the intermediate transmission gear 5 to rotate.

[0024] The cooling box 3 is also rotatably connected to two working shafts 6, which are symmetrically installed. Each working shaft 6 is fixedly connected to a working gear 7, which meshes with the intermediate transmission gear 5. When the intermediate transmission gear 5 rotates, it drives the two working shafts 6 to rotate through the gear meshing. The other end of each working shaft 6 rotates through the cooling box 3. Each working shaft 6 is fixedly connected to a rotating fan blade 8 near the end of the cooling box 3. The two rotating fan blades 8 cooperate with the cooling box 3. When the rotating fan blades 8 rotate, they create a blowing cooling effect, thereby cooling the pastries and preventing burns to staff. Both rotating fan blades 8 have a six-blade structure, which improves the cooling effect.

[0025] The cooling box 3 is also equipped with a transmission assembly, which includes a positioning plate 9 installed on the outer wall of the cooling box 3 away from the conveying device 2 via a disassembly assembly. The disassembly assembly includes a disassembly plate 13 fixedly connected to the positioning plate 9. The disassembly plate 13 and the cooling box 3 cooperate with each other. The disassembly plate 13 has multiple bolt holes, and each bolt hole is equipped with a disassembly bolt 14. The multiple disassembly bolts 14 cooperate with the multiple bolt holes, so that the staff can quickly disassemble and install, which facilitates the inspection and maintenance of parts. The end of the intermediate transmission column 4 away from the cooling box 3 is rotatably connected to the positioning plate 9. The ends of the two working shafts 6 away from the cooling box 3 are also rotatably connected to the positioning plate 9, which improves the stability during rotation.

[0026] An auxiliary pad is fixedly connected to the outer wall of the positioning plate 9, and a working motor 10 is fixedly connected to the auxiliary pad. The working motor 10 is detachable and can be rotated through the positioning plate 9. A bevel gear 11 is fixedly connected to the output end of the working motor 10. A bevel gear 2 12 is fixedly connected to the end of the intermediate transmission column 4 away from the cooling box 3. The bevel gear 11 and bevel gear 2 12 are meshed with each other, so that when the working motor 10 is started, it drives the intermediate transmission column 4 to rotate through gear meshing.

[0027] During the use of this utility model, when the pastry moves out of the tunnel oven body 1 along with the conveying device 2, the operator starts the working motor 10, which causes the bevel gear 11 fixedly connected to the output end of the working motor 10 to start rotating. Due to the meshing characteristics of the gears, the bevel gear 12 will also start rotating, thereby driving the intermediate transmission column 4 to rotate, which in turn causes the intermediate transmission gear 5 fixedly connected to the intermediate transmission column 4 to rotate.

[0028] Due to the meshing characteristics of gears, the two working gears 7 meshing with the intermediate transmission gear 5 will start to rotate, thereby driving the two working shafts 6 to rotate, which in turn causes the rotating fan blades 8 fixedly connected to the working shafts 6 to rotate. At this time, the airflow rate in the cooling box 3 will be changed, thereby achieving the effect of blowing air to cool down the pastries, effectively preventing staff from getting burned. At the same time, staff only need to turn the disassembly bolts 14 to disassemble and install the positioning connecting plate 9, which is convenient for regular maintenance of parts.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
