Description

Technical Field

[0001] This invention relates to the field of tea-making technology, and in particular to a method for separating tea flowers during the scenting process. Background Technology

[0002] In existing technology, scented tea is a special type of tea made by adding various flowers to tea leaves. The traditional scenting method for tea mainly includes the following steps: selecting high-quality tea leaves and fresh flowers, spreading the tea leaves and flowers separately, mixing the tea leaves and flowers in a certain proportion, spreading the tea mixture on the ground or platform, letting it sit to release and absorb the fragrance, turning it manually from time to time to allow the fragrance to be absorbed by the tea leaves, separating the tea leaves and flowers after the scenting process, removing the flowers that have lost their fragrance, and drying the tea leaves that have absorbed the fragrance.

[0003] However, while this traditional method can produce scented teas with specific aromas, it has several limitations. First, fresh flowers have a long time to mature and release their fragrance, and once released, the aroma diffuses rapidly, meaning the tea leaves cannot efficiently absorb it during the scenting process, resulting in significant waste. Second, after the scenting process, the tea leaves and flowers need to be separated, a step that is not only tedious and time-consuming but also costly, increasing overall production costs and labor intensity. Furthermore, the separation process may damage the tea leaves, affecting not only the quality of the final product but also limiting the scale and efficiency of scented tea production. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a tea-flower separation scenting method that ensures tea leaves can uniformly absorb aroma during the scenting process, improves the utilization rate of floral fragrance, avoids solid fresh flowers from mixing into the tea leaves, and greatly simplifies the process of separating tea leaves from flowers after scenting.

[0005] To achieve the above objectives, the present invention provides a tea-flower separation scenting method, which provides a fragrance-emitting cylinder, a scenting cylinder, and a fragrance-returning cylinder arranged in a concentric structure from the inside out, comprising the following steps:

[0006] S100. Place fresh flowers evenly in the fragrance-emitting cylinder and tea leaves evenly in the scenting cylinder;

[0007] S200. Fresh air is introduced into the fragrance tube, and the fragrance tube is driven to rotate at a predetermined speed for a predetermined time to release the fragrance of the flowers;

[0008] S300. Drive the scenting cylinder to rotate, so that the tea leaves can absorb the floral fragrance emitted through the air holes on the circumferential surface of the scenting cylinder;

[0009] S400. The floral fragrance that has not been absorbed by the tea leaves is collected into the fragrance return tube through the air vents on the circumferential surface of the scenting tube.

[0010] S500. The floral-scented air stored in the incense burner is transported back to the incense exhalation burner;

[0011] S600. Repeat steps S200 to S500 until the scenting process is complete, and the scented tea is obtained.

[0012] To improve the efficiency of aroma absorption, the aroma-emitting cylinder, the scenting cylinder, and the aroma-returning cylinder are sequentially connected to form a closed aroma circulation loop, and the pressure in this aroma circulation loop is greater than atmospheric pressure.

[0013] To ensure that the tea leaves come into fuller contact with the aroma, the rotation speeds of both the aroma-emitting cylinder and the scenting cylinder are configured to be independently adjustable.

[0014] A further proposed solution is to have the aroma-emitting tube and the scenting tube rotate in the same direction.

[0015] In order to more effectively promote the release of aroma, the aroma-emitting tube is provided with an air inlet pipe arranged along its axial direction. One end of the air inlet pipe is connected to an external air source, and the other end extends into the aroma-emitting tube. Furthermore, the air inlet pipe has air delivery holes evenly distributed on the circumferential surface of the aroma-emitting tube.

[0016] To ensure the consistency of the finished flower tea quality, the temperature and humidity of the floral air transported back to the aroma-exhaling cylinder are the same as the temperature and humidity of the fresh air input into the aroma-exhaling cylinder.

[0017] To improve the utilization rate of fragrance, the fragrance return cylinder is connected to a gas storage buffer tank. The floral fragrance air stored in the gas storage buffer tank is mixed with fresh air and then delivered to the fragrance release cylinder.

[0018] To improve the aroma transfer efficiency and tea absorption capacity during the scenting process of jasmine tea, multiple reversing paddles are provided in both the aroma-exhaling cylinder and the scenting cylinder. These reversing paddles divide the internal space of the aroma-exhaling cylinder and the scenting cylinder into multiple dwelling areas along a first direction parallel to the axial direction of the aroma-exhaling cylinder. Each reversing paddle has a first side end and a second side end. The first side end extends to the second side end in an arc-shaped structure, and an opening is formed between the first side end and the second side end. A reversing mechanism is provided in the opening of each reversing paddle. The reversing mechanism is used to drive the first side end and the second side end of the corresponding reversing paddle to move away from or towards each other in the first direction, so that the first side end of any reversing paddle connects with the second side end of the previous reversing paddle in its direction of movement to form a continuous spiral conveying path.

[0019] To enable simple and effective control of the commutator paddles, the commutator mechanism includes:

[0020] The first sliding block is located at the first side end of the reversing lever;

[0021] The second sliding block is located at the second side end of the reversing lever corresponding to the first sliding block;

[0022] A reversing shaft, arranged along a second direction perpendicular to the first direction, is used to transmit driving force;

[0023] The reversing gear is located between the first and second sliding blocks on the same reversing paddle and is fixedly connected to the reversing shaft coaxially.

[0024] The worm gear is located between the first and second sliding blocks on the same reversing lever and is fixedly connected to the reversing shaft coaxially.

[0025] A reversing worm gear is positioned in the first direction and meshes with the worm wheel;

[0026] The drive motor is used to drive the commutator worm gear to rotate;

[0027] The first and second sliding blocks each have teeth on their opposite surfaces that mesh with the reversing gear.

[0028] The tea-flower separation scenting method provided by this invention utilizes the relative independence of the aroma-exhaling cylinder and the scenting cylinder. Only the pure aroma released by the fresh flowers in the aroma-exhaling cylinder is allowed to enter the scenting cylinder through the vent holes, while the solid fresh flowers are effectively isolated. This ensures that the tea can absorb the aroma evenly during the scenting process, while preventing solid fresh flowers from mixing into the tea. This greatly simplifies the process of separating the tea and flowers after scenting. In addition, the aroma that is not absorbed by the tea enters the aroma-returning cylinder through the scenting cylinder, is collected, temporarily stored, and finally flows back to the aroma-exhaling cylinder for recycling, thus improving the utilization rate of the fresh flowers.

Detailed Implementation

[0038] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0039] Example 1.

[0040] Please refer to Figure 1 and Figure 2 The tea flower separation scenting method described in this embodiment provides a fragrance-emitting cylinder 10, a scenting cylinder 20, and a fragrance-returning cylinder 30 arranged in a concentric structure from the inside out.

[0041] The specific steps involved in the scenting process are as follows:

[0042] S100. Place fresh flowers evenly in the fragrance-spraying cylinder 10 and tea leaves evenly in the scenting cylinder 20.

[0043] Specifically, the fragrance-emitting tube 10, the scenting tube 20, and the fragrance-returning tube 30 are all placed horizontally. Fresh flowers (such as jasmine, gardenia, osmanthus, etc.) and high-quality tea leaves are selected as raw materials. The fresh flowers are evenly placed inside the fragrance-emitting tube 10 along the axial direction, while the tea leaves are evenly placed inside the scenting tube 20 along the axial direction.

[0044] S200. Fresh air is introduced into the fragrance tube 10, and the fragrance tube 10 is driven to rotate at a predetermined speed for a predetermined time to release the fragrance of the flowers.

[0045] Specifically, after the flowers are placed, filtered and humidity-controlled fresh air is introduced into the fragrance diffuser 10 to help maintain the purity of the fragrance. Simultaneously, the fragrance diffuser 10 is driven to rotate at a predetermined speed for a predetermined time, referring to... Figure 2As shown, the flowers can be flipped to the highest point by the fragrance tube 10. Then, under the action of their own gravity, they will fall and tumble in a cycle. That is, the rotation of the fragrance tube 10 and the flow of fresh air work together to promote the release of the flowers' natural fragrance.

[0046] S300. Drive the scenting cylinder 20 to rotate, so that the tea leaves can absorb the floral fragrance emitted through the vent holes on the surface of the aroma-emitting cylinder 10.

[0047] Specifically, the scenting cylinder 20 is rotated by an external drive device, and the tea leaves are also turned to the highest point by the scenting cylinder 20. Then, under the action of their own gravity, they will fall and turn in a cycle. At the same time, they absorb the emitted floral fragrance through the vent holes (not shown in the figure) on the circumferential surface of the aroma-emitting cylinder 10, so that the tea leaves can come into contact with and absorb the floral fragrance over a larger area.

[0048] S400. The floral fragrance that has not been absorbed by the tea leaves is collected into the fragrance return tube 30 through the air vents on the circumferential surface of the scenting tube 20.

[0049] Specifically, during the rotation of the scenting cylinder 20, the floral fragrance that has not been absorbed by the tea leaves is collected through the air holes on the circumferential surface of the scenting cylinder 20 and introduced into the outermost fragrance-returning cylinder 30. This step effectively recovers the unabsorbed fragrance and reduces the loss of fragrance.

[0050] It should be noted that the vents mentioned in the above steps are configured to allow only fresh air to pass through, and not solids such as flowers and tea leaves.

[0051] S500. The floral fragrance air stored in the fragrance return tube 30 is transported back to the fragrance return tube 10.

[0052] Optionally, the temperature and humidity of the scented air returned to the fragrance exhalation cylinder 10 by the fragrance return cylinder 30 are the same as the temperature and humidity of the fresh air input into the fragrance exhalation cylinder 10. Specifically, the recycled scented air may contain moisture evaporated from fresh flowers or tea leaves. After the scented air has been regulated in terms of temperature and humidity, it is then returned to the fragrance exhalation cylinder 10. This step is beneficial to the consistency of the scenting process, and at the same time, the recycled scented air reduces the demand for fresh flowers, thereby reducing production costs.

[0053] S600. Repeat steps S200 to S500 until the scenting process is complete, and the scented tea is obtained.

[0054] In this way, through repeated cycles, the tea leaves can absorb the floral fragrance evenly and deeply, resulting in a flower tea with a rich aroma and consistent quality. The floral fragrance does not overflow, and the utilization rate of the floral fragrance is high. Only the fresh flowers inside the fragrance release cylinder are allowed to release pure fragrance into the scenting cylinder 20, while effectively isolating solid fresh flowers. This simplifies the process of separating the tea leaves from the flowers after scenting, and naturally avoids the damage that may be caused to the tea leaves during the separation process, thus improving the quality of the final product.

[0055] In some embodiments, the aroma-emitting cylinder 10, the scenting cylinder 20, and the aroma-returning cylinder 30 are sequentially connected to form a closed aroma circulation loop, and the pressure within the aroma circulation loop is greater than atmospheric pressure.

[0056] Specifically, refer to Figure 3 As shown, the aroma-emitting cylinder 10 and the scenting cylinder 20 are connected through the vent holes on the circumferential surface of the aroma-emitting cylinder 10. The scenting cylinder 20 and the aroma-returning cylinder 30 are connected through the vent holes on the circumferential surface of the scenting cylinder 20. The aroma-returning cylinder 30 is connected to the aroma-emitting cylinder 10 through a pipe not shown in the figure, thus forming a closed aroma circulation loop. In this closed aroma circulation loop, the pressure level is usually higher than the standard atmospheric pressure, generally 1.1 times the standard atmospheric pressure. This slightly higher pressure environment helps the aroma components dissolve and absorb in the tea, thereby improving the scenting efficiency and the aroma absorption capacity of the tea.

[0057] In some embodiments, in order to make the tea leaves come into fuller contact with the aroma, the rotation speed of the aroma-emitting cylinder 10 and the scenting cylinder 20 are both configured to be independently adjustable, and the rotation directions of the aroma-emitting cylinder 10 and the scenting cylinder 20 are the same.

[0058] In this way, the independently adjustable rotation speed allows the rotation speed of the cylinder to be adjusted according to actual needs at each stage of the scenting process, thereby optimizing the aroma absorption efficiency. For example, in the early stages of scenting, to promote the full release of floral fragrance from the fresh flowers, the rotation speed of the aroma-exhaling cylinder 10 can be set relatively high, thus accelerating the release of floral fragrance. Simultaneously, since the aroma-exhaling cylinder 10 and the scenting cylinder 20 rotate in the same direction, this ensures that the fresh flowers and tea leaves tumble in the same direction within the cylinder. This consistency greatly increases the opportunity for the tea leaves to come into contact with the aroma (see reference). Figure 2 As shown, the fragrance emitted by the turning flowers travels through the shortest path to the tea leaves, further improving the efficiency of aroma absorption.

[0059] In some embodiments, refer to Figure 3As shown, the fragrance-returning cylinder 30 is connected to a gas storage buffer tank 40. The floral-scented air stored in the gas storage buffer tank 40 is mixed with fresh air before being delivered to the fragrance-exhaling cylinder 10. The gas storage buffer tank 40 can store the floral fragrance that has not been absorbed after the scenting process, which reduces the demand for fresh flowers in mass production and helps to reduce raw material costs. In addition, the gas storage buffer tank 40 can serve as an intermediate link to mix the collected floral-scented air with fresh air and redistribute it to balance the pressure changes in the fragrance circulation loop.

[0060] In some embodiments, refer to Figure 2 and Figure 3 As shown, to more effectively promote the release of fragrance, the fragrance-emitting tube 10 is provided with an air inlet pipe 50 arranged along its axial direction. One end of the air inlet pipe 50 is connected to an external air source, and the other end extends into the fragrance-emitting tube 10. Furthermore, the air inlet pipe 50 has air delivery holes evenly distributed on its circumferential surface within the fragrance-emitting tube 10. This structural design ensures that the airflow can be evenly distributed from one end to the other, promoting the circulation of fresh air throughout the fragrance-emitting tube 10. In other words, fresh air can be evenly delivered into the fragrance-emitting tube 10 through the air delivery holes, which helps to evenly extract and release the fragrance components from the flowers.

[0061] In some embodiments, refer to Figures 3 to 8 As shown, in order to improve the aroma transfer efficiency and tea absorption capacity during the scenting process of jasmine tea, both the aroma-exhaling cylinder 10 and the scenting cylinder 20 are provided with multiple reversing paddles 70. The multiple reversing paddles 70 divide the internal space of the aroma-exhaling cylinder 10 and the scenting cylinder 20 into multiple dwelling areas 60 along a first direction parallel to the axial direction of the aroma-exhaling cylinder 10. Each reversing paddle 70 has a first side end 71 and a second side end 72. The first side end 71 extends to the second side end 72 in an arc-shaped structure, and an opening is formed between the first side end 71 and the second side end 72. A reversing mechanism 90 is provided in the opening of each reversing paddle 70. The reversing mechanism 90 is used to drive the first side end 71 and the second side end 72 of the corresponding reversing paddle 70 to move away from each other or move closer to each other in the first direction, so that the first side end 71 of any reversing paddle 70 is connected to the second side end 72 of the previous reversing paddle 70 in its moving direction to form a continuous spiral conveying path 80.

[0062] Thus, the deformation of the reversing lever 70 is controlled by the reversing mechanism 90; that is, when the reversing mechanism 62 does not act on the reversing lever 70, the deformation is controlled by reference to... Figure 3 , Figure 6 and Figure 8As shown, the first end 71 and the second end 72 of the reversing paddle 70 are aligned, meaning that the planes on which the reversing paddles 70 are located are parallel to each other, thus dividing multiple stopping areas 60 along the axial direction of the cylinder (10, 20); and when the reversing mechanism 62 acts on the reversing paddle 70, referring to Figure 6 and Figure 7 As shown, the first end 71 and the second end 72 of the reversing lever 70 are offset from each other in the first direction to form Figure 6 The spiral conveyor path 80 is shown.

[0063] Utilizing the formed spiral conveying path 80, during feeding, as the aroma-exhaling cylinder 10 or the scenting cylinder 20 rotates, the material (tea leaves or fresh flowers) can move along a predetermined spiral trajectory and be evenly distributed inside the cylinder. This process ensures the uniform distribution of the material inside the cylinder, laying the foundation for the subsequent scenting process. After feeding is completed, the reversing mechanism 90 controls the reversing paddle 70 to divide the aroma-exhaling cylinder 10 or the scenting cylinder 20 into multiple dwelling zones 60. This prevents the material from piling up in these dwelling zones 60 as the cylinders (10, 20) rotate and tumble, thus ensuring that the fresh flowers release their aroma in the best condition, while allowing the tea leaves to fully contact the aroma, optimizing the scenting effect. After the scenting process is completed, the reversing mechanism 90 controls the reversing paddle 70 to reshape the spiral conveying path 80. This path will guide the scented tea leaves out of the scenting cylinder 20 as the cylinder reverses, so that they can be processed in the next step, such as drying or packaging.

[0064] In this embodiment, the reversing paddle 70 is detachably fixed to the inner wall of the cylinder (10,20) so that it deforms under the drive of the reversing mechanism 62 to form a spiral conveying path 80. The durability of the metal reversing paddle 70 enables it to withstand long-term cyclic use and resist wear and tear.

[0065] Specifically, in order to control the reversing paddle 70 simply and effectively, the reversing mechanism 90 includes:

[0066] The first sliding block 91 is located at the first side end 71 of the reversing lever 70;

[0067] The second sliding block 92 is located at the second side end 72 of the reversing lever 70 corresponding to the first sliding block 91;

[0068] The reversing shaft 93 is arranged along a second direction perpendicular to the first direction and is used to transmit driving force;

[0069] The reversing gear 94 is located between the first sliding block 91 and the second sliding block 92 on the same reversing paddle 70, and is coaxially and fixedly connected to the reversing shaft 93.

[0070] The worm gear 95 is located between the first sliding block 91 and the second sliding block 92 on the same reversing lever 70, and is coaxially and fixedly connected to the reversing shaft 93.

[0071] The reversing worm gear 96 is positioned in the first direction and meshes with the worm wheel 95;

[0072] Drive motor 97 is used to drive the commutator worm gear 96 to rotate;

[0073] The first sliding block 91 and the second sliding block 92 are provided with teeth 98 on their opposite surfaces that mesh with the reversing gear 94.

[0074] During operation, the drive motor 97 starts, driving the reversing worm 96 (arranged along the first direction) to rotate. As the reversing worm 96 rotates, the worm wheel 95 starts to drive the reversing shaft 93 to rotate, which in turn drives the reversing gear 94 to rotate. Since the reversing gear 94 meshes with the teeth 98 on the first sliding block 91 and the second sliding block 92, precise control of the first side end 71 and the second side end 72 in the first direction is achieved. Thus, according to the rotation direction of the reversing worm 96, the first side end 71 and the second side end 72 of the reversing paddle 70 are staggered or aligned with each other, realizing the formation and release of the spiral conveying path 80.

[0075] Understandably, each reversing lever 70 opening is provided with a reversing mechanism 90. The reversing worm gear 96 corresponding to multiple reversing mechanisms 90 in a single cylinder (10, 20) can be made into a single piece to achieve synchronous operation of multiple reversing mechanisms 90 driven by a single drive motor 97.

[0076] The tea-flower separation scenting method provided in this embodiment utilizes the relative independence of the aroma-exhaling cylinder and the scenting cylinder. Only the pure aroma released by the fresh flowers in the aroma-exhaling cylinder is allowed to enter the scenting cylinder through the vent holes, while the solid fresh flowers are effectively isolated. This ensures that the tea can absorb the aroma evenly during the scenting process, while preventing solid fresh flowers from mixing into the tea. This greatly simplifies the process of separating the tea and flowers after scenting. In addition, the aroma that is not absorbed by the tea enters the aroma return cylinder through the scenting cylinder, is collected and temporarily stored, and finally flows back to the aroma-exhaling cylinder for recycling, thus improving the utilization rate of the fresh flowers.
