Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, specifically to a light-based drying device for drying Luocheng rice flour. Background Technology
[0002] Rice noodles, a traditional rice product with a long history and widespread popularity, enjoy a broad consumer market in Asia, especially in China and Southeast Asia. Most traditional rice noodles prioritize a smooth and chewy texture, neglecting the need for unique flavor profiles. As people's living standards improve, consumers have higher expectations for rice noodles that offer diverse flavors. Depending on the processing method, rice noodles can be divided into fermented and non-fermented rice noodles. During fermentation, the metabolic products of microorganisms can alter the composition of rice, forming flavor precursors that can contribute to unique flavor compounds during subsequent processing. However, currently reported fermented rice noodles tend to have a shallow fermentation level, with fermentation times not exceeding six days, and their volatile flavor compounds are primarily saturated aldehydes.
[0003] Luocheng rice noodles are a type of deeply fermented rice noodle, fermented for 20-60 days, and its production technique is listed as a provincial intangible cultural heritage of Jiangxi Province. The drying of Luocheng rice noodles relies on sun-drying. During the deep fermentation process, flavor precursors undergo transformation, resulting in a flavor primarily composed of volatile enanthral compounds. These enanthral compounds are common flavor compounds in fermented meat products, contributing to the unique flavor of Luocheng rice noodles. However, the reliance on weather conditions for production severely hinders the scale of Luocheng rice noodles' market development. Furthermore, the use of electric heating drying technology not only makes the noodles prone to clumping but also significantly reduces the content of enanthral flavor compounds, affecting the quality of the noodles.

[0036] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0037] The structure of the light drying device in this embodiment is as follows: Figures 1-5 As shown, the light drying device includes a fan assembly 1, a transmission assembly 2, a rubbing assembly 3, a heating assembly 4, a lighting assembly 5, and a controller 6. The heating assembly 4 is located at the bottom of the light drying device, the fan assembly 1 is located at the top, and the transmission assembly 2, the rubbing assembly 3, and the lighting assembly 5 are located in the middle. The controller 6 is connected to the fan assembly 1, the transmission assembly 2, the rubbing assembly 3, the heating assembly 4, and the lighting assembly 5, and is used to control the opening, closing, and operating intensity of these components. In this embodiment, the controller 6 is located at the top of the light drying device. Since the structure and principle of the controller are well known to those skilled in the art, they will not be described in detail in this embodiment.
[0038] Specifically, the fan assembly 1 includes a circulating fan 11, which is located on top of the light drying device and connected to the controller 6, for blowing and drying the Luocheng rice powder on the transmission assembly 2.
[0039] The transmission component 2 includes a first row of mesh belt conveyors 21, a second row of mesh belt conveyors 22, and a third row of mesh belt conveyors 23 arranged sequentially from top to bottom. These conveyors are horizontally positioned and include conveyor belts, motors, and other components. The motors drive the conveyor belts, thereby transporting the Luocheng rice powder placed on them. Through the transmission of multiple mesh belt conveyors, the Luocheng rice powder circulates within the drying device, allowing for a continuous supply of new undried Luocheng rice powder and improving drying efficiency.
[0040] In this embodiment, the first row of mesh belt conveyors 21, the second row of mesh belt conveyors 22, and the third row of mesh belt conveyors 23 rotate clockwise, counterclockwise, and clockwise respectively, so that Luocheng rice flour circulates and is heated, and new undried Luocheng rice flour can be continuously added, thereby improving drying efficiency.
[0041] The light drying device is also equipped with a material outlet 7 and a material inlet 8, such as Figure 1 As shown, the material inlet 8 is located at the upper part of the lamp drying device, and the material outlet 7 is located at the lower part of the lamp drying device; as Figure 2 As shown, the material inlet 8 is located above the first row of mesh belt conveyors 21. Specifically, an inclined feed plate is provided at the material inlet 8 so that the Luocheng rice powder entering from the material inlet 8 can fall onto the first row of mesh belt conveyors 21. The material outlet 7 is located below the third row of mesh belt conveyors 23. Specifically, an inclined discharge plate is provided at the material outlet 7 so that the Luocheng rice powder conveyed from the third row of mesh belt conveyors 23 can fall onto the discharge plate and be discharged through the material outlet 7.
[0042] The rubbing assembly 3 includes a first placement plate 31, a second placement plate 32, and multiple rubbing rods 33. The inner walls of the first placement plate 31 and the second placement plate 32 are arc-shaped and are respectively located above the first row of mesh belt conveyors 21 and the second row of mesh belt conveyors 22, that is, above the conveyor belts. Specifically, the inner walls of the first placement plate (31) and the second placement plate (32) are concave arc-shaped and are used to install the rubbing rods 33, so that the rubbing rods 33 can contact the Luocheng rice powder conveyed on the first row of mesh belt conveyors 21 and the second row of mesh belt conveyors 22.
[0043] Specifically, the rubbing rod 33 is disposed on the inner wall of the first placement plate 31 and the second placement plate 32. The rubbing rod 33 is specifically composed of a drive motor 333, a rotating rod 332 and rotating beads 331. The rotating beads 331 are disposed facing the conveyor belts on the first row of mesh belt conveyors 21 and the second row of mesh belt conveyors 22, so that they can adhere to the surface of Luocheng rice noodles and have a certain fixing effect on Luocheng rice noodles. This allows the Luocheng rice noodles to be turned over smoothly along the arc-shaped placement plates 31 and 32, so that they dry evenly. At the same time, the drive motor 333 drives the rotating rod 332 to rotate, so that the rotation direction of the rotating beads 331 is opposite to the conveying direction of Luocheng rice noodles, causing the Luocheng rice noodles to spread out in one direction and preventing them from clumping together.
[0044] The heating component 4 includes a heater 41 for heating the Luocheng rice flour on the first row of mesh belt conveyors 21, the second row of mesh belt conveyors 22, and the third row of mesh belt conveyors 23.
[0045] The illumination component 5 includes an infrared lamp 51, a first ultraviolet lamp 52, and a second ultraviolet lamp 53, such as... Figure 3 As shown, infrared lamp 51 is positioned at the top of the first row of mesh belt conveyors 21, while first ultraviolet lamp 52 and second ultraviolet lamp 53 are positioned on the side walls of the light-drying device, specifically near the side walls of the first row of mesh belt conveyors 21, the second row of mesh belt conveyors 22, and the third row of mesh belt conveyors 23. Specifically, the infrared wavelength of the infrared lamp is 2-25 μm, and its radiant heat energy can quickly penetrate deep into the Luocheng rice flour to dry the moisture; the ultraviolet wavelength of the first ultraviolet lamp 52 and the second ultraviolet lamp 53 is 280-400 nm, which can promote the conversion of flavor precursor substances.
[0046] The controller 6 is connected to the fan assembly 1, the transmission assembly 2, the rubbing assembly 3, the heating assembly 4, and the light assembly 5. By controlling the intensity of other components, it controls the drying rate of Luocheng rice flour, thereby ensuring that Luocheng rice flour is fully dried.
[0047] Therefore, the Luocheng rice flour is circulated and moved by the transmission component 2, and the rotating Luocheng rice flour is broken up by the rubbing component 3 to prevent it from sticking together. The Luocheng rice flour is dried evenly by the light component, the heating component, and the fan component. This ensures that the flavor precursor substances produced during the deep fermentation process can be fully converted to form Luocheng rice flour rich in aldehyde flavor substances.
[0048] In actual use, all switches in controller 6 are turned on. After preheating, the wet powder of Luocheng rice flour is placed into the drying device through the material inlet 8. It is conveyed by the first mesh belt conveyor 21 to the rubbing rod 33 on the placement plate 31. After being rubbed and broken by the rotating beads 331, it slides along the arc surface of the placement plate 31 and is turned over. Then, it is conveyed by the second mesh belt conveyor 22 to the rubbing rod 33 on the placement plate 32, where it is rubbed and turned over again, and then conveyed by the third mesh belt conveyor 23 to the material outlet 7. After a long period of conveying and turning, Luocheng rice flour is quickly, evenly and thoroughly dried under the action of infrared lamp 51, first ultraviolet lamp 52, second ultraviolet lamp 53, heater 41, and circulating fan 11, and is rich in aldehyde flavor substances and has good quality characteristics.
[0049] 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.
