Description

Technical Field

[0001] This utility model relates to a tea drying equipment, specifically a dynamic tea dryer capable of sieving powdered tea. Background Technology

[0002] The main processes in tea processing include picking, withering, fixing, rolling, and drying. These processes vary slightly depending on the type of tea, but overall they are all aimed at achieving the best taste and quality.

[0003] Tea drying typically utilizes dryers. Currently, the most common type of dryer is the drum dryer. Drum dryers have spiral blades inside, which push the tea leaves from the inlet to the outlet. The inventors discovered that the spiral blades only move the tea leaves during the drying process and do not shape them. Furthermore, the sides of the drying drum are completely enclosed, and powder is generated during the drying process. This powder accumulates inside the drum and, due to the high temperature, burns, producing a smoky flavor. The tea leaves absorb this smoky flavor, thus affecting their quality. Therefore, to address the shortcomings of existing technology, a dynamic tea dryer capable of sieving powdered tea has been developed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dynamic tea drying machine capable of sieving powdered tea.

The two auxiliary roller components support the rotation of one roller.

[0009] Furthermore, the drying drum also includes a roller and a support ring, and a screen cylinder is installed between two adjacent rollers, with at least one support ring fitted onto the screen cylinder.

[0011] Furthermore, the unloading mechanism includes a base frame; an unloading trough, the top of which is open, one end is closed, and the other end is open and connected to a second unloading chute; the unloading trough is connected to the base frame by at least four second elastic plates, the second elastic plates being installed at an angle; an air supply duct, the air supply duct being placed at the bottom of the unloading trough, one end being installed on a support frame, and the other end being installed on the base frame; a blower, the blower being installed in the air supply duct; and a second propulsion mechanism, the second propulsion mechanism being drivenly connected to the unloading trough.

[0012] Further, the second propulsion mechanism includes a second worktable; a second drive shaft, one end of which is mounted on the second worktable via a fourth bearing seat, and the other end of which is mounted on the second worktable via a third bearing seat; a second rotating shaft, both ends of which are mounted on the bottom of the unloading chute via fifth bearing seats; a second push rod, one end of which is connected to the second rotating shaft, and the other end of which extends downwards and is connected to the second drive shaft; a third driven wheel, which is drivenly connected to the second drive shaft; a second drive motor, which has a second output shaft; and a second driving wheel, which is keyed to the second output shaft and drivenly connected to the third driven wheel.

[0013] Furthermore, the feeding mechanism includes a feeding frame; a feeding trough, the top of which is open, one end is closed, and the other end is open and connected to a first unloading chute; the feeding trough is connected by at least four first elastic plates, the first elastic plates being installed at an angle; and a first propulsion mechanism, the first propulsion mechanism being installed on the feeding frame and being drivenly connected to the feeding trough.

[0014] Further, the first propulsion mechanism includes a first worktable; a first drive shaft, one end of which is mounted on the first worktable via a first bearing seat, and the other end of which is mounted on the first worktable via a second bearing seat; a first driven wheel, which is mounted on the first drive shaft; a first motor, which has a first output shaft; a second drive wheel, which is mounted on the first output shaft and is drively connected to the first driven wheel; a first rotating shaft, both ends of which are mounted on the bottom of the feed trough via first bearing seats; and a first push rod, one end of which is connected to the first drive shaft, and the other end of which extends upward at an angle and is connected to the first rotating shaft.

[0016] The advancements of this invention compared to the prior art are as follows:

[0017] 1. This utility model features a tea powder sieving function. Specifically, the drying drum is equipped with multiple sections of screen cylinders. These screen cylinders filter the tea powder produced during drying, separating it from the tea leaves in a timely manner. The filtered tea powder falls into a collection basket for recycling, preventing the accumulated tea powder from burning and producing a smoky smell, thus improving the quality of the dried tea. Multiple de-clumping guide strips are spirally distributed inside the drying drum. These strips rotate with the drum, pushing and moving the tea leaves upwards, thus turning the tea leaves and ensuring even heating. Furthermore, the rotating strips collide with the tea leaves, breaking up any clumps or blocks, making the tea leaves more loose and ensuring more thorough and even heating, improving drying efficiency and further enhancing the quality of the dried tea.

[0018] 2. The sieving cylinder on the drying drum of this utility model filters the tea powder while also expelling the moisture generated during the drying process. The top of the exhaust cap has an exhaust port. When the moisture generated during drying inside the drum enters the exhaust cap through the guide cylinder, the moisture follows the hot air and is expelled upwards from the exhaust port of the exhaust cap. The tea leaves are discharged from the discharge port of the exhaust cap, thus achieving separation of the tea leaves from the moisture.

[0019] 3. The baffle plate of this utility model is suspended at the port of the drying cylinder and spaced apart from the side of the drying cylinder. It does not affect the drying rotation and can also prevent the hot air ejected from the hot air pipe from rushing out in the opposite direction. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments in this application. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0035] Example 1:

[0036] like Figures 1 to 8 As shown in the figure, this embodiment of a dynamic tea drying machine for sieving powdered tea includes a drying cylinder 22, a baffle plate 225, a guide cylinder 24, an exhaust cap 25, a discharge mechanism 201, a collection basket 213, a drying shell 21, and a transmission mechanism. The drying cylinder 22 is rotatably mounted on the support frame 212, and multiple screen cylinders 222 are spaced apart along the length of the drying cylinder 22. Multiple deblocking guide strips 224 are distributed at intervals on the inner side of the drying cylinder 22, and the multiple deblocking guide strips extend in a spiral distribution. The baffle plate 225 is suspended at one end of the drying cylinder 22 and connected to the hot air pipe 215. The baffle plate 225 has a feed inlet 226, which is connected to the feeding mechanism 200. One end of the guide cylinder 24 is connected to the other end of the drying cylinder 22. The exhaust cap 25 is suspended on the other end of the guide cylinder 24, with an exhaust port 251 at the top and a discharge port at the bottom. The discharge mechanism 201 is connected to the discharge port. A collection basket is movably installed at the bottom of each screen cylinder 222. The drying shell 21 covers the drying cylinder 22 and is installed on the top of the support frame 212. The transmission mechanism is connected to the drying cylinder 22.

[0037] like Figure 1 As shown, when the hot air pipe 215 obstructs the supply of tea leaves to the feeding mechanism 200, the hot air pipe can be bent to provide working space above the feeding mechanism for feeding the kneaded tea leaves.

[0038] like Figure 3 As shown, the baffle plate 225 is suspended inside the port of the drying cylinder.

[0039] like Figure 4 As shown, the screen cylinder 222 allows hot air to pass through while filtering the tea powder generated during the drying process inside the drying cylinder. The tea powder falls into the collection basket below the drying cylinder through the screen cylinder, thus achieving the recycling of the tea powder.

[0040] Understandably, such as Figure 1 , 2 As shown, baffles are installed on both sides of the support frame 212. The width of the baffles can extend from the top of the support frame to its middle. This allows the tea powder carried by the hot air in the drying cylinder to fall into the collection basket below as it is blocked by the baffles when it is sprayed outward through the screen cylinder, thus reducing the amount of tea powder lost.

[0041] like Figure 5As shown, multiple de-clumping guide strips are distributed inside the drying drum, extending in a spiral pattern. This overcomes the problem of existing spiral blades that only push the tea leaves without loosening them. The multiple de-clumping guide strips push the tea leaves forward within the drying drum while simultaneously moving them upwards, thus tumbling the tea leaves and ensuring even heating. Furthermore, as the drying drum rotates, the multiple de-clumping guide strips collide with the tea leaves, breaking up any clumps or blocks of tea, making the tea leaves more loose and ensuring more thorough and even heating, thereby improving drying efficiency and the quality of the dried tea.

[0042] like Figure 8 As shown, multiple units of this invention can be used in series to achieve multiple dynamic drying processes. Tea leaves can be transferred between adjacent dynamic dryers via a conveyor.

[0043] It should be noted that, as Figure 8 As shown, a structure for drying tea leaves by connecting multiple dynamic dryers in series is presented. The unloading mechanism of the first dynamic dryer unloads the tea leaves into the first conveyor 300. The first conveyor 300 conveys the tea leaves to the second conveyor 400. The second conveyor 400 unloads the tea leaves into the feeding mechanism of the second dynamic dryer. The unloading mechanism of the second dynamic dryer unloads the tea leaves dried in the second dynamic dryer into the third conveyor 500. The third conveyor 500 conveys the tea leaves to the next conveyor. This process is repeated to connect multiple dynamic dryers in series, thus enabling the tea leaves to be dried multiple times.

[0044] In some alternative embodiments, one structure of the transmission mechanism is provided. The transmission mechanism includes a first driven wheel 217, a first drive motor 221, and a first driving wheel 220. The first driven wheel 217 is mounted to the end face of the drying cylinder 22 by multiple first bolts 218; the first drive motor 221 is provided with a first drive shaft 2211; the first driving wheel 220 is mounted on the first drive shaft 2211, and the first driving wheel 220 is drively connected to the first driven wheel 217.

[0045] The number of the first bolts 218 can be 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or 22, etc. Of course, it is not limited to these; the appropriate number of first bolts can be selected according to the actual needs of the work.

[0046] A transmission connection structure between the first driving gear 220 and the first driven gear 217, wherein the first driving gear 220 and the first driven gear 217 can be connected by meshing transmission. The first driving gear 220 and the first driven gear 217 are gear structures.

[0047] Another transmission connection structure between the first driving pulley 220 and the first driven pulley 217 involves a transmission connection between the first driving pulley 220 and the first driven pulley 217 via a first transmission member 219. When the first transmission member 219 is a transmission belt, the first driving pulley 220 and the first driven pulley 217 form a pulley structure. When the first transmission member 219 is a transmission chain, the first driving pulley 220 and the first driven pulley 217 form a sprocket structure.

[0048] Work style:

[0049] The first drive motor 221 drives the first drive shaft 2211 to rotate, the first drive shaft 2211 drives the first drive wheel 220 to rotate, the first drive wheel 220 drives the first driven wheel 217 to rotate through the first transmission component 219, and the first driven wheel 217 drives the drying drum 22 to rotate.

[0050] In some alternative embodiments, a rotating structure for the drying cylinder is provided, which includes the addition of auxiliary roller components 211 and rollers 23. Two auxiliary roller components 211 are installed in parallel at intervals at both ends of the support frame 212, and rollers 23 are installed at both ends of the drying cylinder 22. The two auxiliary roller components 211 support the rotation of one roller 23.

[0051] The auxiliary roller component can consist of a roller and a support base, with both ends of the roller rotatably mounted on the support base.

[0052] The rollers 23 at both ends of the drying cylinder are each supported by two auxiliary rollers. When the drying cylinder is subjected to rotational driving force, the two auxiliary rollers at both ends of the drying cylinder support the drying cylinder to rotate.

[0053] An installation structure for the auxiliary roller component 211: The auxiliary roller component is installed on the support frame 212 via an auxiliary frame 216.

[0054] In some alternative embodiments, one structure of the drying cylinder is provided. The drying cylinder 22 also includes a roller 2201 and a support ring 223. A screen cylinder 222 is installed between two adjacent rollers 2201, and at least one support ring 223 is sleeved on the screen cylinder 222.

[0055] The screen cylinder 222 can be fitted with 1, 2, 3, or 4 support rings. The support rings can enhance the load-bearing capacity of the screen cylinder and prevent deformation of the screen cylinder.

[0056] Understandably, the sides of the drum are sealed. The screen cylinder filters out tea powder produced during the drying process. The drying drum combines the drum and the screen cylinder to avoid a completely permeable structure. The drum helps to concentrate heat inside the drying drum, maintaining a certain drying temperature and thus achieving the desired tea drying effect.

[0057] In some embodiments, to facilitate observation of the drying status inside the drying drum, a cover 26, a hinge 28, a locking seat 29, and a locking rod 210 are added. The exhaust cap 25 has an observation port 27. One end of the cover 26 is installed on the exhaust cap 25 via the hinge 28. One end of the locking rod 210 is installed on the cover 26 via another hinge 28, and the other end is movably fixed to the exhaust cap 25 via the locking rod 210.

[0058] One possible structure for the locking rod is a screw. The locking seat has a through hole, and the exhaust cap has a corresponding threaded hole. To fix the locking seat to the exhaust cap, the screw is passed through the through hole and then screwed into the threaded hole. Tightening the screw secures the locking seat to the exhaust cap, and the cover closes the observation port. To separate the locking seat from the exhaust cap, the screw is unscrewed, allowing the locking seat to detach and the cover to be opened, enabling staff to observe the drying process inside the drying drum through the observation port. Understandably, if the lighting inside the drying drum is insufficient, a flashlight can be used to shine into the drum through the observation port to increase brightness and facilitate observation.

[0059] In some embodiments, a structure for the unloading mechanism is provided. The unloading mechanism 201 includes a base frame 2017, an unloading trough 20111, an air supply duct 2016, a blower 2012, and a second propulsion mechanism. The top of the unloading trough 2011 is open, one end is closed, and the other end is open and connected to a second unloading inclined chute 2028; the unloading trough 20111 is connected to the base frame 2017 by at least four second elastic plates 2013, which are installed at an angle; the air supply duct 2016 is located at the bottom of the unloading trough 20111, with one end installed on a support frame 2018 and the other end installed on the base frame 2017; the blower 2012 is installed on the air supply duct 2016; and the second propulsion mechanism is drivenly connected to the unloading trough 20111.

[0060] The top of the unloading chute is open to facilitate the feeding of tea leaves. One end of the unloading chute is closed to prevent tea leaves from falling out from that end.

[0061] The air supply duct and the bottom of the unloading chute are separated, and the air supply duct does not affect the movement of the unloading chute.

[0062] Blower 2012 blows air into the air duct, which guides the air to the bottom of the unloading trough, thus cooling the bottom of the trough. The dried tea leaves discharged from the drying cylinder fall into the unloading trough, where heat exchange occurs, indirectly cooling the tea leaves.

[0063] One installation method for the second elastic plate: one end of the second elastic plate is installed on the base frame 2017 via a second angle bracket 2014, and the other end of the second elastic plate is installed on the bottom of the unloading chute 20111 via another second angle bracket. The second angle bracket is fixedly connected to the unloading chute and the base frame via a third bolt 2015.

[0064] like Figure 6 As shown, the second elastic plate 2013 is inclined in the opposite direction of the unloading chute.

[0065] In some embodiments, a structure of the second propulsion mechanism is provided. The second propulsion mechanism includes a second worktable 2021, a second drive shaft 2020, a second rotating shaft 2030, a second push rod 2024, a third driven wheel 2019, a second drive motor 2027, and a second driving wheel 2026. One end of the second drive shaft 2020 is mounted to the second worktable 2021 via a fourth bearing seat 2023, and the other end is mounted to the second worktable 2021 via a third bearing seat 2022; both ends of the second rotating shaft 2030 are mounted to the bottom of the unloading chute 20111 via fifth bearing seats 2029; one end of the second push rod 2024 is connected to the second rotating shaft 2030, and the other end extends downward at an incline and is connected to the second drive shaft 2020; the third driven wheel 2019 is drive-connected to the second drive shaft 2020; the second drive motor 2027 is provided with a second output shaft; the second driving wheel 2026 is keyed to the second output shaft and drive-connected to the third driven wheel 2019.

[0066] One transmission connection structure between the third driven wheel 2019 and the second drive shaft 2020 is as follows: the third driven wheel 2019 and the second drive shaft 2020 are connected by a key.

[0067] A third bearing sleeve 2031 is also installed on the second rotating shaft 2030. The third bearing sleeve 2031 is fixed to the second rotating shaft 2030 and is used to connect with the second push rod 2024.

[0068] A transmission structure for the third driven wheel 2019 and the second driving wheel 2026: The third driven wheel 2019 and the second driving wheel 2026 are connected by a second transmission component 2025.

[0069] Understandably, the second transmission component 2025 is a transmission belt, while the third driven pulley 2019 and the second driving pulley 2026 are both pulleys. Alternatively, the second transmission component 2025 is a transmission chain, while the third driven pulley 2019 and the second driving pulley 2026 are both sprockets.

[0070] One structure of the second drive motor 2027 is a limited-angle motor. It is understood that the reciprocating rotation angle range of the second drive motor can be set according to operational needs. When the second drive motor reciprocates within the set angle range, it drives the third driven wheel 2019 to reciprocate. The third driven wheel 2019 drives the second drive shaft 2020 to reciprocate. The second drive shaft 2020 drives the second push rod 2024 to reciprocate. The second push rod 2024 pushes and pulls the unloading chute 20111 via the second rotating shaft 2020. Supported by multiple second elastic plates, the unloading chute 20111 reciprocates upwards relative to the unloading direction, causing the tea leaves in the unloading chute to be thrown towards the unloading direction. Thus, the tea leaves gradually move towards the second unloading chute and are unloaded from the second unloading chute.

[0071] In some alternative embodiments, one structure of the feeding mechanism is provided. For example... Figure 7 As shown, the feeding mechanism 200 includes a feeding frame 2003, a feeding trough 2001, and a first propulsion mechanism. The top of the feeding trough 2001 is open, one end is closed, and the other end is open and connected to the first unloading chute 2002. The feeding trough 2001 is connected by at least four first elastic plates 20015, which are installed at an angle. The first propulsion mechanism is installed on the feeding frame 2003 and is drivenly connected to the feeding trough 2001.

[0072] The top of the feed trough 2001 is open to facilitate the feeding of tea leaves. One end of the feed trough is closed to prevent the tea leaves from falling out.

[0073] One installation method of the first elastic plate: the two ends of the first elastic plate are respectively installed on the feed trough 2001 and the feed rack 2003 by the first corner bracket 20013. The first corner bracket 20013 is fixedly connected to the feed trough 2001 and the feed rack 2003 by the second bolt 20014.

[0074] like Figure 7 As shown, the first elastic plate is inclined in the opposite direction to the feeding direction. When the feeding trough is subjected to a force by the first propulsion mechanism, the multiple first elastic plates support the feeding trough and push it upwards relative to the feeding direction, causing the tea leaves in the feeding trough to be thrown in the opposite direction of feeding. This facilitates the loosening of the tea leaves during movement.

[0075] It should be noted that the first elastic plate is installed at an angle. When the first propulsion mechanism pushes the feed trough, the first elastic plate swings in a circular motion. The first elastic plate swings in the direction of feeding. Under the constraint of multiple first elastic plates, the feed trough moves upward. The tea leaves in the feed trough follow the upward movement. The feed trough moves upward repeatedly, causing the tea leaves to move continuously in the direction of feeding until they fall from the first discharge chute into the feed inlet 226.

[0076] One structure of the first propulsion mechanism is as follows: The first propulsion mechanism includes a first worktable 20010, a first drive shaft 20018, a first auxiliary wheel 20012, a second moving wheel 2008, a first motor 2007, a first rotating shaft 2005, and a first push rod 20019. One end of the first drive shaft 20018 is mounted on the first worktable 20010 via a first bearing seat 20011, and the other end is mounted on the first worktable 20010 via a second bearing seat 20017; the first auxiliary wheel 20012 is mounted on the first drive shaft 20018; the first motor 2007 is provided with a first output shaft; the second moving wheel 2008 is mounted on the first output shaft and is drively connected to the first auxiliary wheel 20012; both ends of the first rotating shaft 2005 are mounted on the bottom of the feed trough 2001 via first shaft seats 2006; one end of the first push rod 20019 is connected to the first drive shaft 20018, and the other end extends upward at an incline and is connected to the first rotating shaft 2005.

[0077] One structure of the first drive motor is a finite-angle motor. It is understood that the reciprocating rotation angle range of the first drive motor can be set according to operational requirements. When the first drive motor reciprocates within the set angle range, it drives the first auxiliary wheel 20012 to reciprocate.

[0078] A second bearing sleeve 20016 is installed on the first drive shaft 20018. The second bearing sleeve 20016 is used to connect with the first push rod 20019.

[0079] A transmission connection structure between the first auxiliary wheel 20012 and the second driving wheel 2008, wherein the first auxiliary wheel 20012 and the second driving wheel 2008 are connected by a second transmission component 2009. When the second transmission component 2009 is a transmission belt, both the first auxiliary wheel 20012 and the second driving wheel 2008 are pulleys. When the second transmission component 2009 is a transmission chain, both the first auxiliary wheel 20012 and the second driving wheel 2008 are sprockets.

[0080] In some alternative embodiments, a suspension structure for the wind deflector and exhaust cap is provided, with the addition of a bracket 214 and a suspension rod 227. One end of the bracket 214 is connected to the hot air duct 215, and the other end is bent and extended to connect to the drying housing 21; one end of the suspension rod 227 is connected to the exhaust cap 25, and the other end is connected to the drying housing 21.

[0081] The hot air duct 215 is suspended from the drying shell via a bracket 214, while the baffle plate is connected to the hot air duct, and the hot air duct supports the baffle plate suspended inside the drying drum. It is understood that neither the hot air duct nor the baffle plate affects the rotation of the drying drum.

[0082] The exhaust cap 25 is fitted onto the guide cylinder 24 with the support of the suspension rod 227. Understandably, the exhaust cap does not affect the rotation of the guide cylinder along with the drying cylinder.

[0083] like Figure 1 , 2 As shown, a screen 252 is installed at the exhaust port 251 of the exhaust cap 25. The screen 252 prevents debris from falling into the exhaust cap.

[0084] It should be noted that the hot air inside the drying drum enters the exhaust cap through the guide tube and then exits through the exhaust port on the exhaust cap. Understandably, the exhaust cap separates the tea leaves from the hot air. The tea leaves are discharged from the discharge port at the bottom of the exhaust cap, while the hot air is discharged from the exhaust port.

[0085] According to the above embodiments, the working principle of this utility model is as follows:

[0086] Hot air is introduced into the drying cylinder 22 through the hot air pipe 215 to preheat the drying cylinder. The preheating time can be 10 to 30 minutes.

[0087] The tea leaves to be dried are placed into the feeding mechanism 200, which discharges the tea leaves from the inlet 226 into the drying cylinder 22. Multiple de-clumping guide strips inside the drying cylinder 22 extend in a spiral distribution. As the multiple de-clumping guide strips push the tea leaves into the guide cylinder 24, the tea leaves move continuously under the action of the multiple de-clumping guide strips, and can also carry the tea leaves upward. After moving to a certain height, the tea leaves fall down under their own weight. They can also collide with the tea leaves inside the drying cylinder during rotation, thereby breaking up clumps and lumps, making the tea leaves fully loose, improving the drying efficiency and the quality of the dried tea. The tea powder generated during the drying process is filtered through the screen cylinder 222 and falls into the collection basket below the drying cylinder, realizing the recycling of tea powder.

[0088] Multiple de-clumping guide bars push the tea leaves inside the drying cylinder to the guide cylinder 24. The guide cylinder 24 then feeds the tea leaves into the exhaust cap 25. The tea leaves fall through the discharge port of the exhaust cap 25 to the unloading mechanism 201, while hot air is discharged from the exhaust port 251 at the top of the exhaust cap 25. The unloading mechanism 201 then pushes the tea leaves to the next processing step.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
