Description
Technical Field
[0001] This utility model relates to the technical field of tea processing equipment, and more specifically, to a tea stir-frying device for tea production. Background Technology
[0002] Stir-frying is a crucial step in tea production and processing, directly impacting the final quality of the tea. Stir-frying typically occurs after the initial processing (kill-green) and aims to use high temperatures to halt the activity of oxidative enzymes in the tea leaves, thus preserving their color, aroma, and flavor. Proper temperature and time control during stir-frying can enhance the aroma, making it more intense, and improve the flavor, making it smoother and more harmonious. Since tea leaves are brittle after drying, resulting in more broken pieces, the quality of the stir-frying process is affected. Therefore, sifting is necessary after stir-frying.
[0003] Patent CN220875775U discloses a tea-stirring device for tea production, including a support base and a support plate movably connected within the support base. Two fixed frames are symmetrically fixed to the bottom wall of the inner cavity of the support base, and guide pins are movably connected within the fixed frames. Compression springs are sleeved around the guide pins. A rotary motor is mounted on the back of the support base, and a rotating shaft is mounted on the output end of the rotary motor. Two cams are fixed to the outer wall of the rotating shaft. A connecting frame is fixed to the surface of the support plate, and multiple connecting columns are fixed within the connecting frame. A heating cylinder is fixed between the multiple connecting columns, and a storage cylinder is movably connected to the outside of the heating cylinder, with a filter plate fixed inside the storage cylinder. This tea-stirring device for tea production can not only thoroughly stir-fry the tea leaves but also screen them, reducing residue and impurities, thereby ensuring the quality of the tea. However, after the stir-frying is finished, all the tea leaves inside the stir-frying box are poured into the screening box. Then, the screening box is pushed and pulled back and forth manually, so that the broken tea leaves falling into the screening box shake and fall through the sieve holes on the sieve plate into the collection drawer. This still has the problem of low screening and collection efficiency.
[0004] Therefore, there is an urgent need for a tea-stirring device for tea production that can quickly sieve and collect tea leaves and tea leaves fragments during stir-frying. Utility Model Content
[0005] The purpose of this invention is to solve the problem of low efficiency in screening and collecting tea leaves and tea leaves debris in existing tea stir-frying devices. This invention provides a tea stir-frying device for tea production, which can achieve the technical effect of quickly screening and collecting tea leaves and tea leaves debris.
[0006] This utility model is achieved through the following technical solution: a tea-stirring device for tea production, comprising a cylinder, wherein the cylinder is equipped with a support component and a heating mechanism; the bottom of the cylinder is open, and an arc-shaped screen is movably arranged at the opening; the stirring device further comprises a stirring component and a material collection component, wherein the stirring component is arranged within the space enclosed by the cylinder and the arc-shaped screen, and the material collection component comprises a debris box and a tea-collecting box, wherein the debris box is arranged vertically below the arc-shaped screen and movably connected to the support component via a lifting component, and the tea-collecting box is movably mounted on the debris box.
[0007] Preferably, the debris box is formed by an open main box and a movable plate, wherein the movable plate is movably connected to the open main box.
[0008] Preferably, the top of the lidless main box has multiple notches, and the bottom of the tea collection box is detachably connected to a pair of placement strips, the notches being used to embed the placement strips.
[0009] Preferably, the bottom of the movable plate is hinged to the front side of the bottom of the lidless main box.
[0010] Preferably, the support assembly includes a base and a pair of L-shaped side plates, the pair of L-shaped side plates being disposed facing each other on the left and right sides of the cylinder, one end of the pair of L-shaped side plates being detachably connected to the left and right sides of the cylinder respectively, and the other end of the pair of L-shaped side plates being detachably connected to the left and right ends of the base respectively.
[0011] Preferably, the stir-frying assembly includes a rotating shaft and multiple stir-frying plates. The rotating shaft extends through the middle of the cylinder. The multiple stir-frying plates are detachably connected to the rotating shaft via multiple connecting rods. The multiple connecting rods are arranged around the outer periphery of the rotating shaft, and the multiple stir-frying plates are all arc-shaped. The lowest point of each stir-frying plate abuts against the arc-shaped screen.
[0012] Preferably, the rotating shaft is equipped with a rotating motor, which is mounted on the side of one of the L-shaped side plates facing away from the cylinder. One end of the rotating shaft is detachably connected to the output shaft of the rotating motor, and the other end of the rotating shaft extends out of the cylinder and is movably connected to the side of the other L-shaped side plate facing the cylinder through a bearing.
[0013] Preferably, the lifting assembly includes a lifting rod and a telescopic motor. The telescopic motor is mounted on the surface of the base. One end of the lifting rod is detachably connected to the side of the uncovered main box facing the base, and the other end of the lifting rod is detachably connected to the output shaft of the telescopic motor.
[0014] Preferably, the heating mechanism is a heating sleeve, which is fitted around the outer periphery of the cylinder.
[0015] Preferably, the top of the cylinder is provided with a feed inlet, and the feed inlet is hinged with a sealing cap.
[0016] The technical solution of this utility model has the following beneficial effects:
[0017] (1) Before stir-frying the tea leaves, the shavings box is raised to contact the outer wall of the cylinder using the lifting component. During stir-frying, small tea shavings fall into the shavings box through the mesh of the arc-shaped screen. After stir-frying, the shavings box is lowered using the lifting component, which facilitates cleaning of the shavings and allows space to be left between the shavings box and the arc-shaped screen for placing the tea collection box on top of the shavings box. The arc-shaped screen can also be easily disassembled, allowing the stir-fried tea leaves to fall and be collected in the tea collection box. This tea stir-frying device can quickly separate tea leaves and tea shavings while stir-frying, and can quickly collect tea leaves and tea shavings separately. It is easy to use, improves the efficiency of tea leaf and tea shavings separation and collection, improves the processing efficiency of the tea stir-frying process, and allows for easy disassembly and cleaning of the arc-shaped screen to avoid clogging.
[0018] (2) By opening the movable plate, the tea leaves in the debris box can be easily removed. By embedding the placement strip at the bottom of the tea collection box into the multiple notches opened at the top of the lidless main box, the tea collection box can be securely placed on top of the debris box. At this time, the arc-shaped screen can be removed to easily put the tea leaves that have been stir-fried in the cylinder into the tea collection box.
[0019] (3) During stir-frying, the rotating shaft drives the stir-frying plate to rotate. The continuous rotation of the stir-frying plate strikes the arc-shaped screen, causing it to vibrate. This allows the tea leaves to be turned more evenly on the surface, improving the stir-frying effect. It also makes it easier for light impurities and tea fragments to pass through the pores of the arc-shaped screen, thus improving screening efficiency. Furthermore, it prevents relatively moist tea leaves or impurities from accumulating on the screen, ensuring that the arc-shaped screen remains unobstructed, thereby reducing cleaning frequency and improving usage efficiency. The arc-shaped design of the stir-frying plate facilitates the natural flow and turning of the tea leaves during the stir-frying process, ensuring more even heating and preventing tea leaves from sticking together.

The components of the embodiments of the present invention described and shown herein can generally be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] Example 1
[0030] like Figures 1 to 5As shown, this embodiment provides a tea-stirring device for tea production, including a cylinder 1. The cylinder 1 is equipped with a support component 2 and a heating mechanism. The bottom of the cylinder 1 is open, and an arc-shaped screen 3 is movably installed at the opening. The arc-shaped screen 3 is fastened to the outer wall of the cylinder 1 by multiple clips 9. The stirring device also includes a stirring component 4 and a material collection component 5. The stirring component 4 is disposed within the space enclosed by the cylinder 1 and the arc-shaped screen 3. The material collection component 5 includes a debris box 51 and a tea collection box 52. The debris box 51 is disposed vertically below the arc-shaped screen 3 and movably connected to the support component 2 via a lifting component 6. The tea collection box 52 is movably mounted on the debris box 51.
[0031] Before stir-frying the tea leaves, the lifting component 6 raises the debris box 51 to a position close to the outer wall of the cylinder 1. During stir-frying, small tea leaf debris falls into the debris box 51 through the mesh of the arc-shaped screen 3. After stir-frying, the lifting component 6 lowers the debris box 51, facilitating the cleaning of debris and creating space between the debris box 51 and the arc-shaped screen 3 to allow the tea collection box 52 to be placed on top of the debris box 51. The arc-shaped screen 3 can also be easily disassembled, allowing the stir-fried tea leaves to fall and be collected in the tea collection box 52. This tea stir-frying device can quickly separate tea leaves and tea leaf debris while stir-frying, and can quickly collect tea leaves and tea leaf debris separately. It is easy to use, improves the efficiency of tea leaf and tea leaf debris separation and collection, increases the processing efficiency of the tea stir-frying process, and allows for easy disassembly and cleaning of the arc-shaped screen 3, preventing clogging.
[0032] In this embodiment, the debris box 51 is formed by an open-top main box 511 and a movable plate 512, with the movable plate 512 movably connected to the open-top main box 511. Opening the movable plate 512 allows for easy removal of debris.
[0033] In this embodiment, the top of the lidless main box 511 has multiple notches 511a, and the bottom of the tea collection box 52 is detachably connected to a pair of placement strips 53. The notches 511a are used to embed the placement strips 53. The length of the placement strips 53 is slightly longer than the length of the tea collection box 52, making it convenient to pick up the tea collection box 52. When it is necessary to collect the stir-fried tea, the pair of placement strips 53 are embedded in the notches 511a at the top of the lidless main box 511, which can securely place the tea collection box 52 on top of the debris box 51. At this time, the buckle 9 can be opened to remove the arc-shaped screen 3, and the stir-fried tea in the cylinder 1 can be put into the tea collection box 52. The tea collection box 52 has a larger capacity than the debris box 51. The length and width of the tea collection box 52 are both greater than the length and width of the cylinder 1, making it convenient to collect the stir-fried tea. Removing the tea collection box 52 filled with tea makes it easy to transfer the stir-fried tea to the next process. Furthermore, to prevent tea leaves from falling during transportation, a lid (not shown) can be installed on the top of the tea collection box 52.
[0034] In this embodiment, the bottom of the movable plate 512 is hinged to the front side of the bottom of the lidless main box 511, which facilitates the quick opening or closing of the movable plate 512 and makes it convenient for personnel to remove debris.
[0035] In this embodiment, the support component 2 includes a base 21 and a pair of L-shaped side plates 22. The pair of L-shaped side plates 22 are arranged facing each other on the left and right sides of the cylinder 1. One end of the pair of L-shaped side plates 22 is welded to the left and right sides of the cylinder 1 respectively, and the other end of the pair of L-shaped side plates 22 is welded to the left and right ends of the base 21 respectively.
[0036] In this embodiment, the stir-frying assembly 4 includes a rotating shaft 41 and multiple stir-frying plates 42. The rotating shaft 41 is movably inserted through the middle of the cylinder 1. The multiple stir-frying plates 42 are welded to the rotating shaft 41 by multiple connecting rods 43. The multiple connecting rods 43 are arranged around the outer periphery of the rotating shaft 41. One end of the connecting rod 43 is welded to the outer wall of the rotating shaft 41, and the other end of the connecting rod 43 is welded to the end of the stir-frying plate 42. The multiple stir-frying plates 42 are all arc-shaped, and the lowest point of the stir-frying plate 42 abuts against the arc-shaped screen 3.
[0037] During stir-frying, the rotating shaft 41 drives the stir-frying plate 42 to rotate. As the stir-frying plate 42 rotates, it contacts the arc-shaped screen 3. With the continuous rotation of the stir-frying plate 42, it strikes the arc-shaped screen 3, transmitting force to the screen and causing it to vibrate. The vibration of the arc-shaped screen 3 has two advantages: firstly, it allows the tea leaves to be turned more evenly on its surface, improving the heating uniformity and stir-frying effect; secondly, it allows light impurities and tea fragments to pass through the pores of the arc-shaped screen 3 more easily, thus improving screening efficiency; and thirdly, the impact and vibration of the stir-frying plate 42 prevents the accumulation of moist tea leaves or impurities on the screen, ensuring that the arc-shaped screen 3 remains unobstructed, thereby reducing cleaning frequency and improving usage efficiency.
[0038] The 42-curved design of the stir-frying plate helps the tea leaves to flow and turn naturally during the stir-frying process, which can more effectively ensure that the tea leaves are heated evenly and are less likely to stick together.
[0039] In this embodiment, the rotating shaft 41 is equipped with a rotating motor 44 mounted on one of the L-shaped side plates 22 facing away from the cylinder 1. One end of the rotating shaft 41 is connected to the output shaft of the rotating motor 44, and the other end of the rotating shaft 41 extends out of the cylinder 1 and is movably connected to the side of the other L-shaped side plate 22 facing the cylinder 1 via a bearing 45. The rotating motor 44 drives the rotating shaft 41 to rotate, which is convenient to use. Furthermore, the bearing 45 reduces friction, lowers wear, and improves the durability and service life of the equipment.
[0040] In this embodiment, the lifting assembly 6 includes a lifting rod 61 and a telescopic motor 62 mounted on the surface of the base 21. One end of the lifting rod 61 is welded to the side of the uncovered main box 511 facing the base 21, and the other end of the lifting rod 61 is connected to the output shaft of the telescopic motor 62. After stir-frying, the lifting rod 61 is shortened by the telescopic motor 62, allowing the shavings box 51 to be lowered. Then, the movable plate 512 of the shavings box 51 is flipped open, making it easy to remove the tea shavings from the shavings box 51, as well as the filter frame and the stir-fried tea leaves inside.
[0041] In this embodiment, the heating mechanism is a heating sleeve 7, which is fitted around the outer periphery of the cylinder 1. The heating sleeve 7 is prior art in this field, so its specific structure will not be described in detail. The size of the heating sleeve 7 is adapted to the cylinder 1.
[0042] In this embodiment, the feed inlet at the top of the cylinder 1 is hinged with a sealing cover 8, which can be easily opened or closed by flipping the sealing cover 8.
[0043] In this embodiment, the tea-stirring device also includes a controller 10 and a power supply 11. The controller 10 is electrically connected to the telescopic motor 62, the rotary motor 44, and the heating sleeve 7, respectively. The power supply 11 is electrically connected to the controller 10, the telescopic motor 62, the rotary motor 44, and the heating sleeve 7, respectively. The controller 10 can be a microcontroller (e.g., an 8051 series microcontroller, an STM32 series microcontroller), an FPGA programmable controller, etc. The controller 10 controls the telescopic motor 62, the rotary motor 44, and the heating sleeve 7, making it convenient to use. The control circuit can be implemented with simple programming by those skilled in the art, and the provision of the power supply 11 is also common knowledge in the art; therefore, the control method and circuit connection will not be described in detail.
[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
