Description

Technical Field

[0001] The invention relates to the technical field of non-fried instant noodles manufacturing, in particular to a hot air drying process for non-fried instant noodles. Background Art

[0002] Non-fried instant noodles usually have a lower oil content and therefore have relatively fewer calories, making them suitable for consumers who are concerned about healthy eating. The frying process may destroy some water-soluble nutrients (such as vitamin C), while the non-frying process can better preserve these nutrients. Non-fried noodles usually have a softer and more elastic texture than fried noodles, similar to traditional handmade noodles. Trans fats produced during the frying process can have adverse effects on health, but non-fried noodles do not have this problem.

[0003] The processing technology of non-fried instant noodles generally includes: mixing flour, water and other ingredients (such as salt, alkaline water, etc.) and kneading into dough. The dough is pressed into thin sheets by a noodle press and then cut into strips or blocks as needed. The cut noodles are put into a steam device for steaming to ensure that the noodles are cooked and some moisture is removed. The steamed noodles are dried by hot air drying equipment to remove moisture from the noodles. Usually, precise adjustments are made to the temperature and humidity control to ensure uniform drying. The dried noodles are cooled and finally packaged into bags and seasoning packets are added.

[0004] In the prior art, during hot air drying, the mold for storing instant noodles is generally transported by a conveyor. During the process of the mold moving inward during hot air drying, the instant noodles are dried by hot air. Since the instant noodles placed in the mold are relatively wet, and the moisture will also gather downward under the action of gravity, the upper layer of the instant noodles dries faster and the lower layer dries slower. In order to ensure the crispness of the instant noodles, the drying time can only be extended, which reduces the overall drying efficiency. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of low drying efficiency and uneven drying of non-fried instant noodles in the prior art, and to propose a hot air drying process for non-fried instant noodles.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A hot air drying process for non-fried instant noodles comprises the following steps:

[0008] Instant noodles are placed in a mold on a chain conveyor, and the mold has flow holes around it;

[0009] Make the mold entering the hot air drying equipment tumble;

[0010] Take out the dried instant noodles from the mold coming out of the hot air drying equipment.

[0011] The chain conveyor is located upstream of the hot air drying device and has a cover-up station. The mold includes an upper cover and a lower shell. The lower shell is connected to the chain conveyor and is located at the cover-up station to connect the upper cover and the lower shell.

[0012] The chain conveyor is located inside the hot air drying device as a drying station. Located at the drying station, the hot air drying device can blow convection hot air to the mold, and the mold can be rolled at the drying station.

[0013] The chain conveyor is located downstream of the hot air drying device and has a cover removal station, and the upper cover is removed from the lower shell at the cover removal station.

[0014] The chain conveyor includes a plurality of support shafts that can move and rotate following the chain, and a plurality of molds are installed on each of the support shafts. The molds include a lower shell fixed to the support shaft and an upper cover detachably connected to the lower shell. A gear is fixed to the support shaft, and a rack is fixed inside the hot air drying equipment along the conveying direction of the mold, and the gear can mesh and rotate on the rack.

[0015] The lower shell is made of ferromagnetic metal, the lower shell has an open slot cavity, and the upper cover has a magnetic attraction portion that can be magnetically adsorbed to the lower shell.

[0016] The upper cover comprises a main body, one side of the main body has an outer edge, the outer edge can be supported on the open end of the lower shell, and the main body can be embedded in the groove cavity.

[0017] The inner side of the chain conveyor is provided with a positioning support frame, and the bottom of the mold located outside the rack can slide on the positioning support frame.

[0018] The invention proposes a hot air drying process for non-fried instant noodles, which has the beneficial effect that when the device is working, the instant noodles to be dried are placed in a mold, the mold with the instant noodles is sent into the hot air drying equipment through a chain conveyor, and the hot air drying equipment generates a hot air flow to dry the instant noodles in the mold.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 A hot air drying process for non-fried instant noodles comprises the following steps:

[0027] s1. Instant noodles are placed in a mold 2 on a chain conveyor 1, and the mold 2 has flow holes around it;

[0028] s2, rolling the mold 2 entering the hot air drying device 7;

[0029] s3. Take out the dried instant noodles from the mold 2 coming out of the hot air drying equipment 7.

[0030] When the device is working, the instant noodles to be dried are placed in the mold 2, and the mold 2 with the instant noodles is sent to the hot air drying device 7 through the chain conveyor 1. The hot air drying device 7 generates a hot air flow to dry the instant noodles in the mold 2. The mold 2 of the device has flow holes around it and can roll itself, so that the air flow can pass through the instant noodles more evenly, thereby improving the uniformity and drying efficiency of the instant noodles.

[0031] As an embodiment, the chain conveyor 1 is located upstream of the hot air drying equipment 7 and has a cover station 3. The mold 2 includes an upper cover 9 and a lower shell 10. The lower shell 10 is connected to the chain conveyor 1 and is located at the cover station 3 to connect the upper cover 9 and the lower shell 10.

[0032] The mold 2 of the device comprises an upper cover 9 and a lower shell 10. The instant noodles are placed in the lower shell 10, and then the upper cover 9 is installed at the open position of the lower shell 10 manually or by a robot, so that the instant noodles are enclosed in the mold 2. In this way, the instant noodles can be prevented from being deformed when the mold 2 is rolled.

[0033] The chain conveyor 1 is located inside the hot air drying device 7 as the air drying station 4. Located at the air drying station 4, the hot air drying device 7 can blow convection hot air to the mold 2, and the mold 2 located at the air drying station 4 can roll. The mold 2 rolls while moving inside the hot air drying device 7, so that the instant noodles can be evenly contacted with the hot air flow all around, improving the uniformity and efficiency of drying, which is conducive to reducing the overall drying length of the hot air drying device 7.

[0034] The chain conveyor 1 is located downstream of the hot air drying device 7 and has a cover removal station 5, where the upper cover 9 is removed from the lower shell 10. After drying, the upper cover 9 is removed manually or by a robot at the cover removal station 5, so as to facilitate the removal of the instant noodles.

[0035] As a practical approach, refer to Figure 5 In order to facilitate the placement and removal of the upper cover 9, a transmission conveyor is set above the chain conveyor 1. The upper cover 9 is removed from the lower shell 10 by a worker or a robot and placed on the transmission conveyor. The upper cover 9 is transported from the cover removal station 5 to the cover placement station 3 by the transmission conveyor. In this way, a circulation device for the use of the upper cover 9 can be formed, which is convenient for taking and placing the upper cover 9.

[0036] refer to Figure 1-Figure 4 The chain conveyor 1 includes a plurality of support shafts 11 that can move and rotate with the chain, and a plurality of molds 2 are installed on each support shaft 11. The mold 2 includes a lower shell 10 fixed to the support shaft 11 and an upper cover 9 detachably connected to the lower shell 10. A gear 12 is fixed to the support shaft 11, and a rack 8 is fixed in the hot air drying device 7 along the conveying direction of the mold, and the gear 12 can mesh and rotate on the rack 8.

[0037] When the chain conveyor 1 drives the mold 2 on the support shaft 11 to move, when the gear 12 moves to the rack 8, the gear 12 drives the mold 2 to roll under the meshing action. The structure is simple and easy to use. The number of turns of the mold 2 can be determined according to the length of the rack 8 or the number of teeth of the gear 12, which is convenient for determining the final angle of the mold 2 when it moves out of the hot air drying equipment 7.

[0038] The lower shell 10 is made of ferromagnetic metal and has an open slot 13. The upper cover 9 has a magnetic attraction portion that can be magnetically adsorbed to the lower shell 10. The upper cover 9 and the lower shell 10 are combined by magnetic attraction, and disassembly and installation are relatively simple.

[0039] In order to improve the docking stability, the upper cover 9 includes a main body 92, and one side of the main body 92 has an outer edge 91. The outer edge 91 can be supported on the open end of the lower shell 10, and the main body 92 can be embedded in the groove cavity 13, so that the instant noodles in the groove cavity 13 can be better positioned through the main body 92.

[0040] The chain conveyor 1 has a positioning support frame 6 inside, and the bottom of the mold 2 located outside the rack 8 can slide on the positioning support frame 6. Figure 1 The device is provided with a positioning support frame 6. When the mold 2 is out of the position of the rack 8, it moves to the positioning support frame 6. The shape of the positioning support frame 6 matches the movement direction of the chain conveyor 1. This ensures that the mold 2 is in a horizontal state when it moves to the upper cover station 3, which is convenient for putting in instant noodles and placing the upper cover 9. It is in a horizontal state when it moves to the cover removal station 5, which is convenient for removing the upper cover 9 and taking it out, which is conducive to realizing automated work.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and inventive concept of the present invention by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
