Description

Technical Field

[0001] This application relates to the technical field of food drying equipment, and in particular to a non-fried high-temperature air micro-puffing instant noodle drying box unit. Background Technology

[0002] With consumers' increasing health awareness, the market demand for non-fried instant noodles continues to grow due to their low oil and low calorie content. In the production process of non-fried instant noodles, drying is a crucial step, directly affecting the taste, shelf life, and production efficiency. High-temperature air micro-expansion technology, as one of the core processes in non-fried instant noodle production, uses high-temperature air to puff the noodles and remove moisture, while the drying chamber unit is the key equipment for realizing this technology.

[0003] Currently, drying oven units used in the production of non-fried, high-temperature air-puffed instant noodles generally suffer from low drying efficiency during actual operation, making it difficult to meet the needs of large-scale industrial production. Firstly, most drying ovens use a unidirectional hot air conveying structure, resulting in a short and uneven flow path of hot air within the oven. This leads to hot air accumulation and excessively high temperatures in some areas, while other areas experience insufficient hot air coverage and lower temperatures. This uneven hot air distribution causes uneven heating of the instant noodles during the drying process, resulting in slow moisture evaporation in some areas and requiring extended overall drying time to reach the acceptable moisture content standard, severely reducing drying efficiency. Furthermore, uneven heating can easily cause localized hardening and deterioration in taste, affecting product quality. Utility Model Content

[0004] In order to ensure that instant noodles are heated evenly in the drying box, this application provides a non-fried high-temperature air-puffed instant noodle drying box unit.

Finned tube heat exchangers are installed on both sides inside the drying box, and an oil supply component for supplying oil to the finned tube heat exchangers is provided on one side of the drying box.

[0006] By adopting the above technical solution, the air inside the drying chamber is heated by a finned tube heat exchanger, and oil is supplied to the finned tube heat exchanger through an oil supply assembly, ensuring the normal operation of the finned tube heat exchanger. Simultaneously, the return air system allows for the recirculation of air within the drying chamber, reducing energy consumption. Instant noodles are placed on a support plate, and then the drive motor rotates the upper and lower sprockets, moving the chain and the support plate on the chain.

[0011] Optionally, the support plate includes a mounting frame, and multiple support rods are fixedly connected within the mounting frame.

[0012] By adopting the above technical solution, the support plate adopts a structure in which multiple support rods are fixed inside the mounting frame, which can improve air circulation and enhance the drying effect while supporting instant noodles.

[0013] Optionally, the support plate is provided with a limiting sleeve, and the support plate is provided with a limiting component for limiting the position of the limiting sleeve.

[0014] By adopting the above technical solution, a limiting sleeve and a limiting component are set on the carrier plate, which can position the limiting sleeve and ensure its stable position, which helps the instant noodles to be placed on the carrier plate and the drying process to proceed smoothly.

[0015] Optionally, the limiting component includes a limiting clamp that is slidably connected to the support rod.

[0016] By adopting the above technical solution, the position can be flexibly adjusted to limit the position of the limiting sleeve, which helps to ensure the stable placement of instant noodles during the drying process.

[0017] Optionally, the outer wall of the limiting sleeve is provided with multiple ventilation holes.

[0018] By adopting the above technical solution, ventilation holes can be used to...

[0019] Optionally, the return air system includes a centrifuge, the centrifuge is connected to an air supply duct, the air supply duct is connected to a drying chamber, and a return air duct connects the drying chamber and the centrifuge.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0025] The embodiment itself is: a non-fried high-temperature air-puffed instant noodle drying box unit, as shown in the reference. Figure 1 and Figure 2 The system includes a drying chamber 1. In this embodiment, there are three drying chambers 1, and each drying chamber 1 is rectangular. Finned tube heat exchangers 8 are installed on both sides of the drying chamber 1. An oil supply assembly 9 for supplying oil to the finned tube heat exchangers 8 is provided on one side of the drying chamber 1.

[0026] The oil supply assembly 9 includes a thermal oil boiler 91. Each finned tube heat exchanger 8 is connected to an oil inlet pipe 92 and an oil outlet pipe 93. A pneumatic regulating valve 921 is installed on the oil inlet pipe 92. Thus, the thermal oil boiler 91 can supply oil to the finned tube heat exchangers 8, allowing the finned tube heat exchangers 8 to heat the interior of the drying chamber 1.

[0027] A return air system 2 is connected to one side of the drying chamber 1. The air system includes a centrifuge 21, and an air supply duct 22 is connected to the centrifuge 21. The air supply duct 22 is connected to the inside of the drying chamber 1, and a return air duct 23 is connected between the drying chamber 1 and the centrifuge 21.

[0028] Reference Figure 2 and Figure 3 The drying chamber 1 contains an upper sprocket 3 and a lower sprocket 4, with a shared chain 5 running between them. A drive motor 6 is installed outside the drying chamber 1 to rotate the upper sprocket 3 and the lower sprocket 4, and the drive motor 6 is connected to the shaft of the upper sprocket 3. Activating the drive motor 6 drives the upper sprocket 3, which in turn drives the chain 5, causing the lower sprocket 4 to rotate.

[0029] The chain 5 is provided with multiple support plates 10, which are equidistantly arranged along the length of the chain 5. Each support plate 10 has a connecting assembly 7 for connecting it to the chain 5. The connecting assembly 7 includes a connecting rod 71 fixedly connected to the support plate 10. A guide plate 72 is provided on the side of the chain 5 away from the support plate 10, and the guide plate 72 is fixedly connected inside the drying chamber 1. A limiting groove 721 is provided on the guide plate 72 to limit the position of the connecting rod 71. The end of the connecting rod 71 away from the support plate 10 is slidably connected within the limiting groove 721. Therefore, under the limiting effect of the limiting groove 721, the support plate 10 can move stably with the chain 5.

[0030] The support plate 10 includes a mounting frame 101, within which multiple support rods 102 are fixedly connected. A limiting sleeve 11 is provided on the support plate 10, and multiple vent holes are formed on the outer wall of the limiting sleeve 11. A limiting component 12 for limiting the position of the limiting sleeve 11 is provided on the support plate 10. The limiting component 12 includes a limiting clamp 121 slidably connected to each support rod 102.

[0031] Therefore, by sliding the clamp on the support rod 102, the clamp can press the limiting sleeve 11 against the support rod 102, thereby reducing the shaking and displacement of the limiting sleeve 11 and making the instant noodles more stable in position during the drying process.

[0032] Meanwhile, the return air system 2 enables the air inside the drying chamber 1 to be circulated, reducing energy consumption. The instant noodles are placed on the support plate 10, and then the drive motor 6 can be controlled to drive the upper sprocket 3 and the lower sprocket 4 to rotate, which drives the chain 5 and the support plate 10 on the chain 5 to move. The instant noodles move back and forth in the drying chamber 1, so that the instant noodles are heated evenly, improving the drying efficiency of the instant noodles.

[0033] By adopting the above technical solution and installing a pneumatic regulating valve 921 on the oil inlet pipe 92, the amount of oil entering the finned tube heat exchanger 8 can be adjusted, thereby flexibly controlling the temperature inside the drying oven 1.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
