Description

Technical Field

[0001] This application belongs to the field of areca nut roasting technology, specifically a continuous areca nut roasting device. Background Technology

[0002] Areca nut, the fruit of the areca palm (Areca catechu), an evergreen tree belonging to the Areca genus of the palm family, is not only one of the four major traditional Chinese medicines from southern China, possessing effects such as relieving indigestion, resolving phlegm, treating malaria, and killing parasites, but is also considered a chewing favorite in ethnic minority areas of southern China. Because freshly picked areca nuts have a high water content, they are easily invaded by microorganisms and mold, making them difficult to preserve for a long time. Therefore, they need to be roasted to reduce moisture and inhibit microbial growth, which is beneficial for storage and transportation. At the same time, dried areca nuts are easier to slice into thin slices with uniform quality, which can improve the efficiency of subsequent processing and product quality. In addition, roasting and other treatments can extend the shelf life of areca nuts and improve their taste, thereby expanding the sales and consumption scope and significantly enhancing their market value and economic benefits.

[0003] For example, the utility model patent with announcement number CN220018089U discloses a continuous areca nut roasting device, including a workbench, a conveyor belt installed on the surface of the workbench, multiple placement components arranged on the surface of the conveyor belt, a mounting cover installed on the surface of the workbench and located above the conveyor belt, and a drying device located at the top of the inner wall of the mounting cover. The continuous areca nut roasting device provided by this utility model has a drying device installed inside the mounting cover, which works in conjunction with the air blowing component and placement component inside the conveyor belt to facilitate the simultaneous up-and-down roasting of the areca nuts inside the placement component during roasting. At the same time, the placement component drives the areca nuts to rotate evenly, thereby allowing the areca nut surface to be heated and roasted evenly.

[0004] However, in actual use, it was found that the device achieves uniform roasting of areca nuts through the coordinated rotation of the conveyor belt, drying device, and circular filter box in the placement component. However, the circular filter box of this device is set up independently, and the loading capacity of a single box of areca nuts is limited. When producing in large quantities, additional filter boxes and placement components are required, which not only increases the load on the conveyor belt and reduces the stability of operation, but also significantly increases the cost. At the same time, the process of loading areca nuts into the circular filter box is cumbersome and time-consuming and labor-intensive, making it difficult to achieve the production requirement of continuous and uniform roasting. Therefore, a continuous areca nut roasting device is provided. Utility Model Content

[0005] The purpose of this application is to provide a continuous areca nut roasting device in order to solve the problems mentioned above.

A pulley is fixedly installed on the outer surface of one end of the rotating shaft and the installation shaft. A transmission belt is sleeved on the outer surface of the pulley. A drive mechanism connected to the rotating shaft is provided on one side of the U-shaped sealing cover.

[0007] In a preferred embodiment, the heating assembly includes a conical heating cover, an electric heating tube, a motor, and a fan blade.

[0008] In a preferred embodiment, the drive mechanism includes a motor bracket and a universal motor. The motor bracket is fixedly installed on one side of the U-shaped sealing cover, and the universal motor is fixedly installed on one side of the motor bracket. The drive end of the universal motor passes through one side of the motor bracket and is fixed to one end of the rotating shaft.

[0009] In a preferred embodiment, a heat collection shell is fixedly installed on the bottom surface of the conveyor belt support, and two heat recovery pipes are fixedly installed on one side of the heat collection shell, with manual valves fixedly installed on the outer surface of each of the two heat recovery pipes.

[0011] In a preferred embodiment, an inclined guide plate is fixedly installed at the left end of the conveyor belt support below the metal mesh conveyor belt.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: 1. In this application, due to the adoption of the above-mentioned scheme, the general-purpose motor drives the rotating shaft to rotate, causing the flexible striking strip on the roller to continuously strike the metal mesh conveyor belt and areca nuts, causing the areca nuts to vibrate. This not only avoids stacking and sticking, but also promotes uniform heating of the surface. Moreover, when the rotating shaft rotates, it drives the mounting shaft to rotate through the pulley and transmission belt. When the cam on the mounting shaft rotates to the top, it contacts the bottom of the metal mesh conveyor belt and lifts the bottom, causing the conveyor belt to vibrate and assisting the areca nuts to turn over. This can further ensure uniform heating. After the baking is completed, the device causes the metal mesh conveyor belt to vibrate through the coordinated rotation of the roller, flexible striking strip, mounting shaft and cam, causing the areca nuts to continuously shift and turn over during the conveying process, significantly improving the baking uniformity and realizing continuous and efficient areca nut baking operation.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] refer to Figures 1-3As shown, a continuous areca nut roasting device includes a conveyor belt support 1, inside which a metal mesh conveyor belt 2 is installed. An inclined guide plate 17 is fixedly installed at the left end of the conveyor belt support 1 below the metal mesh conveyor belt 2. A conveyor belt drive motor is installed on one side of the conveyor belt support 1. Two conveying gears are rotatably connected to the left and right ends of the conveyor belt support 1, respectively. The conveying gears are connected to the metal mesh conveyor belt 2, and the conveyor belt drive motor is connected to one of the conveying gears. This facilitates the rotation of the metal mesh conveyor belt 2, thereby ensuring the continuous conveying of areca nuts on the metal mesh conveyor belt 2, guaranteeing the continuity of roasting, and improving production efficiency. The inclined guide plate 17 facilitates the automatic sliding and collection of roasted areca nuts, reducing manual operation and improving work smoothness.

[0017] refer to Figures 1-3 As shown, a U-shaped sealing cover 3 is fixedly installed on the top surface of the conveyor belt support 1. A heating component 4 is installed inside the U-shaped sealing cover 3. A heat collection shell 14 is fixedly installed on the bottom surface of the conveyor belt support 1. Two heat recovery pipes 15 are fixedly installed on one side of the heat collection shell 14, and manual valves are fixedly installed on the outer surface of the two heat recovery pipes 15. A baffle is installed inside the U-shaped sealing cover 3 near the left and right ends. The U-shaped sealing cover 3 and the baffle can reduce heat loss and improve roasting efficiency, while preventing external impurities from entering and affecting the quality of betel nuts. The heat collection shell 14 and the heat recovery pipes 15 can be used to recover and utilize the waste heat generated during roasting, reducing energy consumption. The manual valves can easily control the flow rate and on / off of the heat recovery. The heat recovery pipes 15 can be connected to an external heat recovery system for convenient subsequent utilization of the heat.

[0018] refer to Figures 1-3 As shown, the heating assembly 4 includes a conical heating shroud 401, an electric heating tube 402, a motor 403, and a fan blade 404. Two conical heating shrouds 401 are fixedly installed inside the U-shaped sealing cover 3, and multiple electric heating tubes 402 are fixedly installed inside each of the two conical heating shrouds 401. Multiple motors 403 are fixedly installed on the top surface of the U-shaped sealing cover 3, and the drive ends of the multiple motors 403 extend into the interior of the conical heating shrouds 401. The drive ends of the motors 403 are fixedly installed with fan blades 404. An air supply pipe 16 is fixedly installed at the top of the conical heating shroud 401, and the end of the air supply pipe 16 away from the conical heating shroud 401 is connected to an external air filter. The electric heating tubes 402 provide a stable heat source. The conical heating shroud 401, together with the fan blades 404, can make the hot air evenly distributed inside the U-shaped sealing cover 3, ensuring that the areca nuts are heated evenly and improving the roasting quality. The air supply pipe 16 is connected to an air filter, which can filter the air entering the heating area and ensure a clean roasting environment.

[0019] refer to Figures 1-3As shown, bearing seats 5 are fixedly installed on the left and right sides of the U-shaped sealing cover 3, and a rotating shaft 6 is fixedly installed through the middle of the bearing seat 5. A roller 7 is fixedly installed on the outer surface of the rotating shaft 6, and multiple flexible striking strips 8 are installed in a circumferential array on the outer surface of the roller 7. During the areca nut conveying and roasting process, the drive mechanism drives the rotating shaft 6 to rotate, so that the flexible striking strips 8 on the roller 7 strike the areca nuts conveyed on the metal mesh conveyor belt 2, which can make the areca nuts vibrate, so that the surface of the areca nuts is heated more evenly, while avoiding the stacking of areca nuts from affecting the roasting effect, and also preventing the areca nuts from sticking together. The flexible striking strips 8 can be made of polytetrafluoroethylene material, which is almost unaffected by the physical properties under high temperature roasting environment, and has a low surface friction coefficient.

[0020] refer to Figures 1-3 As shown, bearing seats 2 9 are fixedly installed on the left and right sides of the conveyor belt bracket 1, and a mounting shaft 10 is fixedly installed through the middle of the bearing seat 2 9. A cam 11 is fixedly installed on the outer surface of the mounting shaft 10 near the middle. A pulley 12 is fixedly installed on the outer surface of one end of the rotating shaft 6 and the mounting shaft 10, respectively. A transmission belt is sleeved on the outer surface of the pulley 12. A drive mechanism 13 connected to the rotating shaft 6 is provided on one side of the U-shaped sealing cover 3. Through the drive mechanism 13, the rotating shaft 6, pulley 12, transmission belt and mounting shaft 10 can be driven to rotate, thus realizing the linkage between the rotating shaft 6 and the mounting shaft 10. During the rotation, the top of the cam 11 on the mounting shaft 10 contacts the bottom of the metal mesh conveyor belt 2, thereby causing the metal mesh conveyor belt 2 to move up and down and vibrate. This facilitates the turning of the areca nuts during the conveying process and further improves the uniformity of the areca nuts during the roasting process. The structure is compact and the transmission is stable.

[0021] refer to Figures 1-3 As shown, the drive mechanism 13 includes a motor bracket 1301 and a universal motor 1302. The motor bracket 1301 is fixedly installed on one side of the U-shaped sealing cover 3, and the universal motor 1302 is fixedly installed on one side of the motor bracket 1301. The drive end of the universal motor 1302 passes through one side of the motor bracket 1301 and is fixed to one end of the rotating shaft 6. The universal motor 1302 facilitates the rotation of the rotating shaft 6, thereby allowing the mounting shaft 10 to rotate together under the drive of the pulley 12 and the transmission belt. The motor bracket 1301 ensures that the motor is installed securely. By controlling the motor speed, the operating speed of the rotating shaft 6 and other components can be flexibly adjusted to adapt to different baking requirements.

[0022] The implementation principle of a continuous areca nut roasting device according to this application is as follows: The user places the areca nuts to be roasted on a metal mesh conveyor belt 2. Driven by a motor and gears, the metal mesh conveyor belt 2 rotates continuously, feeding the areca nuts into a U-shaped sealing cover 3. At this time, the heating component 4 is activated, and the electric heating tube 402 generates heat. The motor 403 drives the fan blades 404 to circulate hot air within the conical heating cover 401 and the U-shaped sealing cover 3, achieving uniform roasting of the areca nuts. Simultaneously, the universal motor 1302 in the drive mechanism 13 drives the rotating shaft 6 to rotate, causing the flexible striking strips 8 on the roller 7 to continuously strike the metal mesh conveyor belt 2 and the areca nuts, causing the areca nuts to vibrate. This not only prevents stacking and adhesion but also… It can promote uniform heating of its surface. Moreover, when the rotating shaft 6 rotates, it drives the mounting shaft 10 to rotate through the pulley 12 and the transmission belt. When the cam 11 on the mounting shaft 10 rotates to the top, it contacts the bottom of the metal mesh conveyor belt 2 and lifts the bottom, causing the conveyor belt to vibrate and assisting the areca nuts to turn over. This can further ensure uniform heating. After the baking is completed, the areca nuts move with the metal mesh conveyor belt 2 and slide down through the inclined guide plate 17 to complete the collection. The device uses the coordinated rotation of the roller 7, the flexible striking strip 8, the mounting shaft 10 and the cam 11 to make the metal mesh conveyor belt 2 vibrate, causing the areca nuts to continuously shift and turn over during the conveying process, which significantly improves the baking uniformity and realizes continuous and efficient areca nut baking operation.
