Description
Technical Field
[0001] This invention relates to the field of tea drying technology, and in particular to a drying apparatus for processing Camellia chrysantha. Background Technology
[0002] Golden camellia is a health drink or food made primarily from golden camellia (Camellia nitidissima Chi). Known as the "Queen of Teas" due to its golden flowers, golden camellia has high nutritional and medicinal value. During processing, it requires drying.
[0003] A search revealed a Chinese patent publication number CN 213811402U, which discloses a drying device for Camellia chrysantha, comprising: a heating chamber, which is a hollow cylindrical structure, with a first opening on the top surface of the heating chamber, a fan on the bottom surface of the heating chamber, a heating plate above the fan, and an air inlet on the side wall of the heating chamber near the bottom surface; a tray, which has four plum blossom-shaped holes for placing Camellia chrysantha; and a drying chamber, which is a hollow frustum structure, with a second opening on the side wall of the drying chamber.
[0004] The aforementioned patent has the following shortcomings: it still only uses hot air as a medium to dry Camellia chrysantha, and the energy density of hot air is relatively low, so its heating efficiency for Camellia chrysantha is relatively low, resulting in low drying efficiency. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a drying device for processing Camellia chrysantha.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A drying device for processing Camellia chrysantha includes a base and a drying box fixed to the top outer wall of the base. The top and bottom of the drying box are respectively provided with an air outlet and an air inlet. The air outlet and the air inlet are connected to a hot air supply dehumidification mechanism. A rotating table is rotatably connected to the bottom inner wall of the drying box, and a tray module is provided on the top of the rotating table.
[0008] The tray module is composed of multiple vertically arranged hollow trays, and the inner wall of each hollow tray is fixedly embedded with multiple heating wires for heating the hollow tray.
[0009] The hollowed-out trays are interconnected with each other and with the rotating platform via a set of connecting components.
[0010] The hot air supply dehumidification mechanism includes an air dehumidification device and a hot air generating device. The hot air outlet of the hot air generating device is connected to the air inlet through a pipeline, and the air outlet is connected to the inlet of the air dehumidification device through a pipeline. The dehumidification outlet of the air dehumidification device and the inlet of the hot air generating device are connected through a pipeline.
[0011] Preferably, the air outlet and the air dehumidification device are connected by an air pump for gas drive and a humidity sensor for acquiring air humidity information.
[0012] Furthermore, the connecting assembly includes a transmission cam shaft disposed at the bottom of the hollowed-out tray and a transmission sleeve disposed at the top of the hollowed-out tray and the top of the rotating platform, wherein the transmission sleeve and the transmission cam shaft cooperate with each other.
[0013] Based on the aforementioned scheme: each set of connecting components includes two sets of parallel conductive components. The conductive components include a fixed post and a movable post with conductivity. The fixed post installed at the hollow tray is embedded in the inner wall of the transmission sleeve and the transmission convex shaft. The fixed post installed at the rotary table is embedded in the inner wall of the entire rotary table. The two fixed posts located in the hollow tray are electrically connected to the two power supply terminals of the heating wire, respectively.
[0014] A preferred embodiment of the aforementioned scheme is that a movable column is movably mounted on the inner wall of the junction between the transmission sleeve and the transmission cam, and the bottom of the movable column is connected to the top of the fixed column by an insulating spring.
[0015] As a further aspect of the present invention, the fixed column located within the rotating platform is in the form of a broken line.
[0016] Meanwhile, the bottom of the fixed column is electrically connected to a second fixed column via a conductive spring. The second fixed column is slidably connected to the inner wall of the rotating table, and a conductive ring is fixed on the inner surface of the bottom of the drying box, which slides or rolls in contact with the second fixed column. The conductive ring is connected to an external power source.
[0017] As a preferred embodiment of the present invention: the bottom outer wall of the drying oven is fixed with a motor by bolts, and the motor is driven and coupled to the bottom outer wall of the rotating table.
[0018] Meanwhile, a limiting ring is fixed to the bottom upper surface of the drying oven, and the rotating platform is movably fitted inside the limiting ring. A support plate is fixed to the bottom outer wall of the rotating platform by bolts. A roller is rotatably connected to the bottom of the support plate through a wheel axle. The roller rolls and fits into the bottom upper surface of the limiting ring. A plurality of limiting protrusions that cooperate with the rollers are fixed to the bottom upper surface of the limiting ring.
[0019] As a preferred embodiment of the present invention: a transmission cylinder is fixed to the bottom outer wall of the rotary table, and a spline shaft is fixed to the output shaft of the motor, with the spline shaft movably inserted into the inner wall of the transmission cylinder.
[0020] The beneficial effects of this invention are as follows:
[0021] 1. This invention, based on heating Camellia chrysantha with hot air by setting up a hot air generating device, adds an electric heating wire to heat the perforated tray, thereby achieving a dual heating function for Camellia chrysantha, thus increasing the heating efficiency and drying efficiency of Camellia chrysantha.
[0022] 2. In addition to increasing the quality of Camellia chrysantha dried in a single batch by setting multiple hollow trays, the multiple hollow trays can be easily disassembled and assembled sequentially through connecting components. At the same time, the easy disassembly and assembly also makes the connection between hollow trays, the loading and unloading of Camellia chrysantha in the hollow trays easier, further improving efficiency.
[0023] 3. This invention, based on the connection components that facilitate the assembly and disassembly of the perforated tray, further enhances drying efficiency by incorporating conductive components. These components enable the circuit to be connected or disconnected simultaneously with the perforated tray or the rotating table, thus avoiding messy and unsightly wire connections. Furthermore, by setting the conductive components as a combination of a fixed column, a movable column, and an insulating spring, when there is no matching perforated tray on the top of the perforated tray or the rotating table, the insulating spring lifts the movable column, preventing it from contacting the spring and thus ensuring it remains unenergized. This prevents the safety issues associated with exposed energized components.
[0024] 4. In this invention, while ensuring uniform drying by setting a rotatable perforated tray, the inclusion of components such as a fixed column and a conductive ring enables it to function as an "electric slip ring," ensuring that the heating wire is powered without wires and preventing problems such as wire tangling caused by rotation.
[0025] 5. In this invention, while ensuring uniform drying by rotating the rotating table, the combination of rollers and limiting protrusions enables the rotating table and the hollow tray to move up and down periodically. The vibration of the up and down movement not only has a certain stirring effect on the camellia, ensuring uniform drying, but also allows the broken pieces of camellia to fall down step by step, thus achieving a screening function.

[0036] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0037] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0038] Example 1:
[0039] A drying device for processing Camellia chrysantha, such as Figures 1-9 As shown, the device includes a base 1 and a drying box 4 fixed to the top outer wall of the base 1. The top and bottom of the drying box 4 are respectively provided with an air outlet 5 and an air inlet 6. The air outlet 5 and the air inlet 6 are connected to a hot air supply dehumidification mechanism. The bottom inner wall of the drying box 4 is rotatably connected to a rotating table 2, and a tray module 3 is provided on the top of the rotating table 2.
[0040] The tray module 3 is composed of multiple longitudinally arranged hollow trays 9, and multiple heating wires 10 for heating the hollow trays 9 are fixedly embedded in the inner wall of the hollow trays 9.
[0041] The hollowed-out trays 9 are interconnected with each other and with the rotary table 2 via a set of connecting components 11.
[0042] The hot air supply dehumidification mechanism includes an air dehumidification device 7 and a hot air generating device 8. The hot air outlet of the hot air generating device 8 is connected to the air inlet 6 through a pipeline, and the air outlet 5 is connected to the inlet of the air dehumidification device 7 through a pipeline. The dehumidification outlet of the air dehumidification device 7 and the inlet of the hot air generating device 8 are connected through a pipeline.
[0043] The air outlet 5 and the air dehumidification device 7 are connected by an air pump for gas drive and a humidity sensor for acquiring air humidity information. The humidity information acquired by the humidity sensor can be used to determine whether the humidity of the Camellia chrysantha meets the requirements.
[0044] When using this device, Camellia chrysantha can be placed inside multiple perforated trays 9. During the drying process, the hot air generator 8 is first activated, which heats the air and delivers it to the air inlet 6. The hot air heats and dries the Camellia chrysantha in the perforated trays 9. At the same time, the heating wire 10 is energized, which heats the perforated trays 9, thereby heating the Camellia chrysantha inside the perforated trays 9. The Camellia chrysantha is heated by the perforated trays 9 and the air, and the moisture evaporates into the air. Then, it is discharged through the air outlet 5 and enters the air dehumidification device 7 for dehumidification before entering the hot air generator 8 for heating again, completing the cycle.
[0045] This device, based on the use of hot air to heat Camellia chrysantha by setting up a hot air generating device 8, adds an electric heating wire 10 to heat the hollow tray 9, thereby achieving a dual heating function for Camellia chrysantha, thus increasing the heating efficiency and drying efficiency of Camellia chrysantha.
[0046] To address the convenience issue; such as Figure 3As shown, the connecting component 11 includes a transmission cam 13 disposed at the bottom of the hollow tray 9 and a transmission sleeve 12 disposed at the top of the hollow tray 9 and the top of the rotating table 2. The transmission sleeve 12 and the transmission cam 13 cooperate with each other. In this embodiment, the cross-sectional shape of the cooperation between the transmission sleeve 12 and the transmission cam 13 is not limited. It can be "I", "+", or polygonal, preferably a regular hexagon.
[0047] When drying and feeding Camellia chrysantha, the Camellia chrysantha can be first loaded into one of the hollow trays 9, and then the transmission cam 13 at the bottom of the hollow tray 9 can be inserted into the transmission sleeve 12. Then, another hollow tray 9 can be loaded with Camellia chrysantha, and then the transmission cam 13 at the bottom of the previous hollow tray 9 can be inserted into the transmission sleeve 12. This process is repeated until all the hollow trays 9 are loaded. The unloading process is the reverse.
[0048] This device, by setting multiple hollow trays 9 to increase the quality of golden camellia dried in one batch, allows the multiple hollow trays 9 to be easily disassembled and assembled sequentially through the connecting component 11. At the same time, the easy disassembly and assembly also makes the connection between hollow trays 9, the loading and unloading of golden camellia in the hollow trays 9 easier, and further improves efficiency.
[0049] To solve the problem of conductive connections; such as Figure 4 , 5 As shown in Figure 9, each set of connecting components 11 includes two sets of parallel conductive components 14. The conductive components 14 include a fixed post 15 and a movable post 16 with conductivity. The fixed post 15 installed at the hollow tray 9 is embedded in the inner wall of the transmission sleeve 12 and the transmission cam 13. The fixed post 15 installed at the rotary table 2 is embedded in the inner wall of the entire rotary table 2. The movable post 16 is movably installed on the inner wall of the joint between the transmission sleeve 12 and the transmission cam 13. The bottom of the movable post 16 is connected to the top of the fixed post 15 through an insulating spring 17. The two fixed posts 15 located in the hollow tray 9 are electrically connected to the two power supply terminals of the heating wire 10.
[0050] When the hollowed-out tray 9 is installed with another hollowed-out tray 9 or with the rotary table 2, the bottom of the fixed column 15 will press down on the movable column 16 until the transmission sleeve 12 and the transmission cam 13 are fully engaged. Then the movable column 16 contacts the insulating spring 17. At this time, the two longitudinally adjacent fixed columns 15 are in a conductive state. However, when there is no hollowed-out tray 9 to engage with the top of the hollowed-out tray 9 or the top of the rotary table 2, the insulating spring 17 will lift the movable column 16. The movable column 16 will not contact the insulating spring 17 and will not be energized.
[0051] This device, based on the connection component 11 for easy assembly and disassembly of the hollowed-out tray 9, incorporates a conductive component 14. This component allows for the connection or disconnection of the circuit while assembling or disassembling the hollowed-out tray 9 with the other hollowed-out tray 9 or the rotary table 2, further increasing drying efficiency and avoiding messy and unsightly wire connections. Furthermore, by configuring the conductive component 14 as a combination of a fixed post 15, a movable post 16, and an insulating spring 17, when there is no matching hollowed-out tray 9 on the top of the hollowed-out tray 9 or the top of the rotary table 2, the insulating spring 17 lifts the movable post 16, preventing contact between the movable post 16 and the insulating spring 17, thus preventing the safety issues associated with exposed live parts.
[0052] To further address the conductivity issue; such as... Figures 5-7 As shown, the fixed column 15 located inside the rotating table 2 is in the shape of a broken line, and the bottom of the fixed column 15 is electrically connected to the fixed column 19 through the conductive spring 18. The fixed column 19 is slidably connected to the inner wall of the rotating table 2, and a conductive ring 20 is fixed on the bottom inner surface of the drying box 4, which slides or rolls in contact with the fixed column 19. The conductive ring 20 is connected to an external power source.
[0053] The bottom outer wall of the drying oven 4 is fixed with a motor 28 by bolts, and the motor 28 is driven by the bottom outer wall of the rotating table 2.
[0054] During the drying process, the motor 28 drives the rotary table 2 to rotate, thereby causing the hollow tray 9 to rotate. During the rotation, the fixed column 19 slides or rolls in contact with the conductive ring 20 to ensure the circuit is connected.
[0055] This device, while ensuring uniform drying by setting a rotatable perforated tray 9, also functions as an "electric slip ring" by setting components such as a fixed column 19 and a conductive ring 20. This ensures that the heating wire 10 is powered without wires and prevents problems such as wire entanglement caused by rotation.
[0056] In this embodiment, when drying and feeding Camellia chrysantha, the Camellia chrysantha is first loaded into one of the perforated trays 9. Then, the transmission shaft 13 at the bottom of the perforated tray 9 is inserted into the transmission sleeve 12. Next, another perforated tray 9 is loaded with Camellia chrysantha, and then the transmission shaft 13 at its bottom is inserted into the transmission sleeve 12 of the previous perforated tray 9. This process is repeated until all perforated trays 9 are loaded. First, the hot air generator 8 is activated, heating the air and delivering it to the air inlet 6. The hot air heats and dries the Camellia chrysantha in the perforated trays 9. Simultaneously, the heating wire 10 is energized, heating the perforated trays 9, thereby heating the Camellia chrysantha within them. The Camellia chrysantha, heated by the perforated trays 9 and the air, evaporates moisture into the air, which is then discharged through the air outlet 5 into the air dehumidifier 7 for dehumidification. Then it re-enters the hot air generating device 8 for heating, completing the cycle. At the same time, when the hollowed-out tray 9 is installed with the hollowed-out tray 9 or the hollowed-out tray 9 with the rotating table 2, the bottom of the fixed column 15 will press down on the movable column 16 until the transmission sleeve 12 and the transmission cam 13 are fully engaged. Then the movable column 16 contacts the insulating spring 17. At this time, the two longitudinally adjacent fixed columns 15 are in a conductive state. When there is no hollowed-out tray 9 to engage with the top of the hollowed-out tray 9 or the top of the rotating table 2, the insulating spring 17 will lift the movable column 16. The movable column 16 does not contact the insulating spring 17 and is not energized. During the drying process, the motor 28 drives the rotating table 2 to rotate, thereby driving the hollowed-out tray 9 to rotate. During the rotation, the fixed column 19 slides or rolls in contact with the conductive ring 20 to ensure the circuit is conductive.
[0057] Example 2:
[0058] A drying device for processing Camellia chrysantha, such as Figures 1-9 As shown, in order to solve the problems of uniformity and screening, this embodiment makes the following improvements based on embodiment 1: a limiting ring 21 is fixed on the bottom upper surface of the drying box 4, the rotating table 2 is movably fitted inside the limiting ring 21, a support plate 22 is fixed to the bottom outer wall of the rotating table 2 by bolts, and a roller 24 is rotatably connected to the bottom of the support plate 22 by a wheel axle 23. The roller 24 rolls and fits on the bottom upper surface of the limiting ring 21, and a plurality of limiting protrusions 25 that cooperate with the roller 24 are fixed on the bottom upper surface of the limiting ring 21.
[0059] A transmission cylinder 26 is fixed to the bottom outer wall of the rotary table 2, and a splined shaft 27 is fixed to the output shaft of the motor 28. The splined shaft 27 is movably inserted into the inner wall of the transmission cylinder 26.
[0060] In this embodiment, when the rotating table 2 rotates, the roller 24 will also rotate and roll along the limiting ring 21. When the roller 24 rotates to the limiting protrusion 25, it will be limited by the limiting protrusion 25 and drive the entire rotating table 2 and the hollow tray 9 to move upward. When it moves away from the limiting protrusion 25, the rotating table 2 and the hollow tray 9 will move downward, thereby generating vibration on the hollow tray 9 by moving up and down.
[0061] This device, while ensuring uniform drying by rotating the rotating table 2, utilizes the cooperation of the roller 24 and the limiting protrusion 25 to enable the rotating table 2 and the hollow tray 9 to move up and down periodically. The vibration of the up and down movement not only has a certain stirring effect on the golden camellia to ensure uniform drying, but also allows the golden camellia fragments to fall down step by step, thus performing a screening function.
[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
