[0049] To better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0050] Embodiment 1, as Figure 1 shown, a transmission device of a new type of tunnel oven is composed of a rotating sprocket 1, a chain 2 and a baking tray 3.

[0051] As Figure 4 shown, the baking tray 3 is composed of an upper cover 31 and a chassis 32, and is used for making rice crust. The upper cover 31 of the baking tray can also be removed and used for preparing cakes or pastries. There are handles 33 at both ends of the chassis 32; there is also a fastening connecting piece 34 above the handles 33. One end of the upper cover 31 and the chassis 32 is hinged through a hinge 35. An opening pulley 36 is installed at the top of the end of the upper cover 31 away from the hinge 35. The upper cover 31 can be opened or closed by the cooperation of the opening pulley 36 and the hinge 35. The upper cover 31 has two ends, one end is hinged to the chassis 32, and the other end is provided with an opening pulley 36.

[0052] As Figure 2 shown, a connecting piece 23 is installed on the chain 2. The connecting piece 23 includes a vertical plate 231 and a horizontal plate 232 connected to each other. The vertical plate 231 is fixedly connected to the side wall of the chain 2, and the horizontal plate 232 is fixedly connected to the head end of the connecting rod 21. The connecting rod 21 is L-shaped. After the tail end of the connecting rod 21 extends a certain distance towards the inside of the chain 2, it horizontally bends towards the middle of the two groups of rotating sprockets 1. A support shaft 22 is installed at the tail end of the connecting rod 21, and the fastening connecting piece 34 is rotatably connected to the support shaft 22.

[0053] The chain 2 rotates under the drive of the rotating sprocket 1. When the baking tray 3 moves from the top to the bottom, the baking tray 3 is rotatably connected to the chain 2 through the fastening connector 34. Under the action of its own gravity, the baking tray 3 does not turn over with the chain 2, but remains in a state with its face up and its bottom down, and smoothly transitions to the bottom. Similarly, when the baking tray 3 moves from the bottom to the top, the baking tray 3 is rotatably connected to the chain 2 through the fastening connector 34. Under the action of its own gravity, the baking tray 3 does not turn over with the chain 2, but remains in a state with its face up and its bottom down, and smoothly transitions to the top, thus following the chain 2 to perform a circular motion.

[0054] A plurality of baking trays 3 are mounted on the chain 2 and circulate to achieve the purpose of baking.

[0055] 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, so as to facilitate the work of taking out the blanks of food and re-closing the food. After taking out the blanks and the food, the baking tray 3 can be automatically closed to enter a new baking process.

[0056] 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.

[0057] The baking method specifically comprises the following steps:

[0058] 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.

[0059] 2. Close the upper cover 31 of the baking tray 3 to seal the wet powder in the baking tray 3.

[0060] 3. Place baking tray 3 into the tunnel oven for baking.

[0061] 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.

[0062] 5. Open the upper cover 31 of the baking tray 3 and place the blank into the slitting machine for slitting to form rice crust blocks of a specific shape, hereinafter referred to as rice crust blocks, such as square blocks.

[0063] 6. Dry the rice crust again or air dry it before frying.

[0064] 7. After frying, you can mix the rice crust with seasonings and package it after cooling.

[0065] Example 3: A method for baking cakes, wherein the upper cover 31 (such as Figure 4 As shown), it is used for preparing cakes or pastries and is operated by a chain 2. Compared with the current pastries rotating from the side, it has the advantages of energy saving and space saving.

[0066] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the said claims.
