Description

Technical Field

[0001] This invention relates to the field of tea production equipment, and in particular to a tea scenting machine. Background Technology

[0002] Scenting is an essential processing technique in the production of scented teas. Scented teas include jasmine tea, magnolia tea, osmanthus tea, and pearl orchid tea, among which jasmine tea has the greatest reputation and production volume. The principle of scenting is to mix tea leaves with fresh flowers. Under the action of enzymes, temperature, moisture, and oxygen, mature fresh flowers decompose and release fragrant substances that penetrate into the tea leaves and are absorbed. While absorbing fragrance, the tea leaves also absorb moisture. Under the action of the humid and hot scenting environment, complex chemical changes occur, causing the tea soup to gradually change from green to bright yellow, and the taste to change from light and astringent to rich and mellow. This creates the unique aroma, color, and taste of scented tea, allowing the tea leaves and floral fragrance to blend together, thus forming a scented tea with distinctive aroma and taste.

[0003] Because the scenting process requires fresh flowers, the flowers must be picked on a sunny day. Flowers picked on a cloudy day will not open properly and cannot be scented. Therefore, the flower buds need to be picked around 10:00 AM. In the afternoon, the picked flowers are graded, inspected, and spread out to dry. Around 8:00 PM, the flowers are "cultivated" to artificially create suitable temperature and humidity to induce the buds to open. Once the buds have opened to a rate of 90% by 9:00 PM, the scenting process can begin. During scenting, the tea leaves and flowers are mixed together and piled thickly. Because fresh flowers contain water... When the tea leaves are piled up thickly and then heated, it is necessary to spread them out thinly in time to dissipate heat. Therefore, the essence of scenting is to continuously pile the tea leaves thickly and spread them out. When piled thickly, the aroma released by the fresh flowers can better blend with the tea leaves and raise the appropriate temperature to promote chemical fusion reaction. Spreading them out thinly can lower the pile temperature, prevent the fresh flowers from becoming stuffy and producing off-flavors, and at the same time promote the addition of oxygen and the contact between the tea leaves and the fresh flowers, thereby further promoting the fusion of the tea leaves and the fresh flowers. This process is carried out at night and takes a long time.

[0004] Currently, the scenting process typically involves piling tea leaves on the floor. During the thin-spreading stage, workers use tools to flatten the tea pile. After cooling, the thinly spread tea leaves are manually scented again. The scenting process is time-consuming, and the higher the quality of the tea, the more times it needs to be scented. Therefore, the frequent piling and thin-spreading of tea leaves during scenting consumes a large number of workers, and the workload is not low. Since workers need to spread the tea leaves from one end of the pile to the other in one go, the whole process takes time. If the thin-spreading is not done in time, the tea pile at the back will experience smoldering or burning, which will reduce the quality of the scented tea. Later, this part of the tea leaves will blend with other tea leaves, which may reduce the quality of the same batch of tea.

[0005] Therefore, in order to further improve the efficiency of scenting tea, the existing technology provides the following solutions: Taking the application number: 202111084979.1, patent name: a scenting equipment for processing flower scented tea, as an example, this invention uses different containers to hold fresh flowers and tea embryos, and places the container containing fresh flowers inside the container containing tea embryos. The container containing fresh flowers is breathable, and the flowers can be fused with the tea embryos without contacting them through a spiral loading method. This eliminates the need for subsequent flower separation processes, thus improving the overall scenting efficiency. This method departs from the traditional scenting process of flower tea. Under the premise that the flower tea and tea embryos are not in direct contact, the actual fusion efficiency cannot be guaranteed, and the quality of the fused flower tea cannot be guaranteed either.

[0006] Existing technologies also include patents with application number 202111623589.7 ("Scented Tea System") and application number 202310867781.3 ("A Scented Tea Device"). Both of these technologies separate the tea leaves from the fresh flowers, relying solely on the fusion of the floral aroma with the tea leaves to eliminate the need for flower processing and improve overall scenting efficiency. However, these devices contradict traditional processing methods. Since the fresh flowers and tea leaves do not come into contact during the scenting process, the scenting efficiency cannot be guaranteed. Therefore, it is impossible to verify whether the overall scenting efficiency of the tea can be effectively improved. Compared to methods that reduce processing steps to improve the scenting of tea, the fundamental way to improve the scenting of tea is to increase the labor intensity and efficiency of workers during the scenting process based on existing technologies. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides a tea scenting machine, which effectively solves the problems mentioned in the background art.

[0008] The technical solution to the problem includes a rotating roller with multiple radial support rods evenly distributed around its two ends. The support rods at both ends of the roller correspond one-to-one and form a group. A material holding platform is provided below each group of support rods. The material holding platform is fixed by rope hoisting. The material holding platform includes a rectangular canvas. A fixed rod along its length is fixed at each of the left and right ends of the canvas. A top rod parallel to the fixed rod is embedded in the middle of the canvas. The two ends of the top rod extend outwards with a length greater than that of the fixed rod. U-shaped grooves are provided at the front and rear ends of the canvas. The openings of the two U-shaped rods face each other. An electric cylinder with its protruding end facing upwards is fixed on the outside of the bottom plate of each U-shaped groove. Two horizontal telescopic rods are hinged in each U-shaped groove. A spring is fitted on the telescopic rod to allow it to return to its original extension. The free end of the telescopic rod is hinged to the fixed rod on the corresponding side via a vertical shaft. When the two telescopic rods in the U-shaped groove rotate to the point where their axes coincide, they are limited by the U-shaped groove. At this time, the canvas is flattened, and at the same time, the protruding end of the electric cylinder moves directly below the top rod.

[0009] Furthermore, a base is provided below the rotating roller, and a bracket is provided at each of the front and rear ends of the base, and the spindle of the rotating roller is rotatably mounted on the corresponding bracket.

[0010] Furthermore, each bracket has an inverted T-shaped rod hinged to its inner side, and each T-shaped rod has a horizontal support extending into the box on its inner side at the lower end. The free end of the support is telescopically fixed to the end of the corresponding fixed rod, and the rope always swings in a vertical plane.

[0011] Furthermore, the upper end of the fixing rod is provided with a baffle along its length.

[0012] Furthermore, a crossbar is fixed to the extended end of the electric cylinder.

[0013] This device employs a three-dimensional scenting process for tea leaves, significantly saving space and improving space utilization, thereby reducing costs. Furthermore, the device can quickly and efficiently transition between thick and thin layers of tea leaves, effectively preventing the tea leaves from becoming stale or burnt due to delayed thinning. The entire transition process is quick and convenient, saving time and labor, thus greatly reducing labor costs and the intensity of work for workers, effectively improving the production efficiency of the scenting process.

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 3As can be seen, the present invention includes a rotating roller 1. To facilitate the installation of the rotating roller 1, a base 11 is provided below the rotating roller 1. A bracket 12 is provided at each of the front and rear ends of the base 11. The spindle of the rotating roller 1 is rotatably mounted on the corresponding bracket 12. Multiple support rods 2 are evenly distributed along the radial direction at both ends of the rotating roller 1. The support rods 2 at both ends of the rotating roller 1 correspond one-to-one and form a group. A material holding platform is provided below each group of support rods 2. The material holding platform is hoisted and fixed by ropes 3. In order to ensure the installation of the ropes 3 and that the electric cylinder 8 does not interfere with the brackets 12 and the base 11 in any state after installation, an inverted T-shaped rod 13 is hinged to the inner side of each bracket 12. A horizontal support part 14 extending into the box is provided on the inner side of the lower end of each T-shaped rod 13. The free end of the support part 14 is telescopically fixedly connected to the end of the corresponding fixed rod 5. The ropes 3 are always kept in place. The material-holding platform, which swings in a vertical plane, includes a rectangular canvas 4. A fixed rod 5 along the length of the canvas 4 is fixed at each of its left and right ends. To block the ends of the canvas 4, a baffle 15 along the length of the fixed rod 5 is provided at the upper end of each fixed rod 5. A top rod 6 parallel to the fixed rod 5 is embedded in the middle of the canvas 4. The top rod 6 extends outwards at both ends with a length greater than that of the fixed rod 5. U-shaped grooves 7 are provided at both the front and rear ends of the canvas 4, with the openings of the two U-shaped rods facing each other. An electric cylinder 8 with its protruding end facing upwards is fixed to the outer side of the bottom plate of each U-shaped groove 7. To prevent the protruding end of the electric cylinder 8 from being unsupported, a horizontal rod 16 is fixed to the protruding end of the electric cylinder 8. Two horizontal telescopic rods 9 are hinged within each U-shaped groove 7. A spring 10 is fitted on the telescopic rod 9 to allow it to return to its original position and extend. The free ends of the telescopic rods are hinged to the corresponding fixed rods 5 via a vertical axis. When the two telescopic rods 9 inside the U-shaped groove 7 rotate to coincide with their axes, they are limited by the U-shaped groove 7. At this time, the canvas 4 is flattened, and the extended end of the electric cylinder 8 moves to directly below the top rod 6.

[0019] The specific working process of this invention is as follows: When using this device, two workers need to simultaneously drive the U-shaped grooves 7 on both sides of the container platform outward, so that the U-shaped grooves 7 move outward. During this process, the two telescopic rods 9 on the same U-shaped groove 7 are in a V-shape, and the two fixed rods 5 are brought together in the middle. The canvas 4 hangs down in the middle to hold the U-shaped cloth bag. As the U-shaped groove 7 moves outward, the electric cylinder 8 also moves outward and makes way for the top rod 6. At this time, the flower tea to be scented is thickly spread along the length of the cloth bag for scenting. The other multiple containers are operated in the same way. The operation process can be achieved by rotating the roller.

[0020] After a period of scenting, when the tea pile temperature rises significantly and it needs to be spread thinly, two workers simultaneously press the U-shaped groove 7 inward, causing it to move inward. During this process, the two telescopic rods 9 move the fixed rod 5 outward, simultaneously flattening the canvas 4. Once the canvas 4 is flattened, continuous pressing of the U-shaped groove 7 drives the telescopic rods 9 to move in the direction of axial alignment, compressing the spring 10 and causing the telescopic rods 9 to retract until their axes align. At this point, under the elastic force of the spring 10 and the limiting action of the U-shaped groove 7, the telescopic rods 9 are limited. The thickly spread tea pile remains thick on the flattened canvas 4. Since the extended end of the electric cylinder 8 is already below the top rod 6, the extension of the electric cylinder 8 is controlled to push the top rod 6... The rod 6 is lifted, causing the middle of the flattened canvas 4 to bulge higher than both ends. During this process, the fixed rod 5 converges towards both ends, and the telescopic rod 9 retracts while the spring 10 is compressed. Under the influence of gravity, the tea pile slides to both sides and spreads thinly. After spreading, the electric cylinder 8 resets. The tea pile can be spread thinly by repeatedly driving the electric cylinder 8 or by reciprocating the extension and retraction of the electric cylinder 8. During the reset of the electric cylinder 8, the canvas 4 is flattened again under the action of the spring 10. At this time, the worker can use the lever to help organize the tea pile after spreading. After heat dissipation, the worker drives the U-shaped groove 7 to move outward again, so that the canvas 4 is reset from the flattened state to the U-shaped cloth bag state. During this process, the tea leaves are restored from the spread state to the thick pile state for scenting again.

[0021] This device has the following advantages:

[0022] 1. Compared with the traditional method of scenting tea leaves on the ground, this device uses a three-dimensional method for scenting tea leaves. This method can save space many times over, thereby improving space utilization and achieving cost savings.

[0023] 2. While traditional scenting methods still rely on ordinary tools to disperse and dissipate heat from thick piles to thin spreads, and to gather and scent tea from thin spreads to thick piles, this device can quickly and efficiently achieve both the transition from thick to thin piles and vice versa. It effectively avoids the problem of tea leaves becoming smothered or burned due to untimely thin spreading. Furthermore, the entire transition process is quick and convenient, saving time and labor, thus significantly reducing labor costs and the labor intensity of workers, thereby effectively improving the production efficiency of scenting.

[0024] 3. This equipment has a lightweight structure, low production cost, and is easy to use. It can effectively meet the current production needs of scented tea, has great market potential, and is easy to promote and apply.
