[0044] To better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0045] Embodiment 1: As Figure 1 shown, a transmission device of a tunnel oven is composed of a rotating sprocket 1, a chain 2, a baking tray 3, and an operating track 4.

[0046] As Figure 5 shown, the baking tray 3 is composed of an upper cover 31 and a chassis 32, and is used for preparing rice crust. The upper cover 31 of the baking tray can also be removed for use in preparing cakes or pastries. Both ends and both sides of the chassis 32 are provided with restraint wheels 33; there are also fastening connectors 34 on both sides of the chassis 32. One end of the upper cover and the chassis is provided with a hinge 35, and the upper cover 31 can be opened or closed by the opening pulley in cooperation with the hinge 35. The upper cover 31 has two ends, one end is rotatably connected to the chassis 32, and the other end is provided with an opening pulley 36.

[0047] As Figure 3 shown, the operating track 4 is composed of an upper track 41, a lower track 42, and a track restrictor 43. Track restrictors 43 are provided at both ends of the operating track 4. The upper track 41 and the lower track 42 are used for the restraint wheels 33 to slide and roll. Both ends of the lower track 42 are respectively connected to the two sets of track restrictors 43. Both ends of the upper track 41 are respectively at a distance from the two sets of track restrictors 43 to form a disconnection gap 44 for the baking tray 3 to pass through, facilitating the smooth transition of the baking tray 3 between the upper track 41 and the track restrictor 43.

[0048] The baking tray 3 is rotatably fastened to the chain 2 through the fastening connector 34. The chain 2 rotates under the drive of the rotating sprocket 1 and drives the baking tray 3 to rotate in a cycle along the operating track 4. The baking tray 3 is rotatably connected to the chain 2 through the fastening connecting chain member 34.

[0049] As Figure 2As shown, driven by the sprocket 1, the constraint wheel 33 slides and rolls on the upper track 41. When the baking tray 3 runs from the upper track 41 to the lower track 42, the constraint wheel 33 on the baking tray 3 enters the track constraint 43, and the baking tray 3 is rotatably connected to the chain 2 through the imprisonment connector 34. Under the action of the track constraint 43, the constraint wheel 33 does not turn over with the chain 2; when the baking tray 3 runs to the disconnection gap 44, the constraint wheel 33 close to the constraint 43 enters the constraint 43 to pass through, and the other constraint wheel passes through the disconnection gap 44; the baking tray 3 always remains in a state of facing up and bottom down, and smoothly transitions to the lower track 42 of the operating track 4, and the constraint wheel 33 slides and rolls on the lower track 42;

[0050] Similarly, when the baking tray 3 runs from the lower track 42 to the upper track 41, the restraining wheel 33 on the baking tray 3 enters the track restraint 43, and the baking tray 3 is rotatably connected to the chain 2 through the locking connector 34. Under the action of the track restraint 43, the restraining wheel 33 does not flip over with the chain 2; when the baking tray 3 runs to the disconnection gap 44, the restraining wheel 33 close to the restraint 43 enters the restraint 43 to pass through, and the other restraining wheel passes through the disconnection gap 44; the baking tray 3 always remains in a face-up, bottom-down state, and smoothly transitions to the upper track 41 of the operating track 4, thus following the chain for a circular motion.

[0051] A plurality of baking trays 3 are mounted on the chain 2 and circulate to achieve the purpose of baking.

[0052] The baking tray cover 31 is provided with an opening pulley 36, which can be opened by a lifting device after the baking tray 3 is taken out of the oven, making it convenient to take out the food blanks and re-lay the food. After taking out the blanks and the food cloth, the baking tray can be automatically closed to enter a new baking process.

[0053] Example 2: A method for baking rice crust. Corn is made into small particles as raw material, and an appropriate amount of millet powder or sesame powder can be added and fully stirred to form powder, hereinafter referred to as powder.

[0054] The baking method specifically comprises the following steps:

[0055] 1. Use a machine to evenly sprinkle the powder on the baking tray 3, and then evenly spray water on the powder in the tray to make the powder into a moist state.

[0056] 2. Close the upper cover 31 of the baking tray 3 to seal the wet powder in the baking tray 3.

[0057] 3. Place baking tray 3 into the tunnel oven for baking.

[0058] 4. Through the control of time and temperature, the moist powder in the baking tray 3 will form a sheet-like blank, hereinafter referred to as blank.

[0059] 5. Open the upper cover 31 of the baking tray 3. After cutting the blank in the cutting machine, form rice cracker pieces of a specific shape, hereinafter referred to as rice cracker pieces, such as square pieces, etc.

[0060] 6. After drying or air-drying the rice cracker pieces again, fry them.

[0061] 7. The fried rice crackers can be mixed with flavoring agents and then packaged after cooling.

[0062] Embodiment 3: A method for baking pastries. Remove the upper cover 31 of the baking tray in Embodiment 1 (as Figure 4 shown), and use it for preparing cakes or pastries. By running on the lower track, compared with the current rotation of pastries from the side end, it has the advantages of energy saving and space saving.

[0063] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
