Description

Technical Field

[0001] This utility model belongs to the technical field of flower tea drying machines, specifically relating to a drum-type flower tea drying machine. Background Technology

[0002] In the processing of scented tea, drying is a crucial step in ensuring its quality and extending its shelf life. There are many existing devices for drying scented tea, with the drum dryer being one of the more common types.

[0003] For example, patent CN222993403U discloses a drying device for osmanthus tea production, including multiple components such as a heating element, a tank, a feed inlet, a discharge outlet, a drum, a lid, and a drive mechanism. In use, the lid is pushed to rotate counter-clockwise, and then the material is fed into the drum through the feed inlet. The lid is then pushed clockwise to seal the drum. The drive mechanism drives the drum to rotate, thereby drying the material inside the drum.

[0004] Undeniably, the drying device for osmanthus tea production disclosed in this patent can indeed achieve the aforementioned effects, but it still has certain shortcomings: the drum cover is movably connected to the inner wall of the drum via two rotating shafts, relying on the shafts to achieve closure. During the drum rotation, the fit between the cover and the inner wall of the drum may decrease due to vibration or the compression of the material inside the drum, causing the cover to rotate and leading to leakage of material inside the drum; the heating tubes are distributed at equal rectangular intervals on the inner wall of the tank, which leads to uneven temperature between the central area of ​​the tank and the area near the heating tubes, affecting the overall drying uniformity. Although the protrusions can support some of the material rotating and being lifted, their effect is limited. Moreover, in order to push the cover, there needs to be a certain distance between the protrusions and the drain plate and the cover, and the material within this distance cannot be lifted by the protrusions, which also affects the overall drying uniformity.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

A rotating component 5 is inserted into the heating jacket 1. The rotating component 5 includes a first rotating circular plate 51 near the heat insulation plate 2, a second rotating circular plate 52 near the support frame 4, a rotating shaft 53 passing through the center of the first rotating circular plate 51 and the second rotating circular plate 52 and fixedly connected to the first rotating circular plate 51 and the second rotating circular plate 52, a plurality of rotating frames 54 arranged circumferentially between the first rotating circular plate 51 and the second rotating circular plate 52, and a reduction motor 55 fixed to the outside of the fixing plate 3 and whose output shaft is connected to the end of the rotating shaft 53 through a coupling; wherein, the two ends of the rotating shaft 53 respectively pass through The heat insulation plate 2, the fixing plate 3, and the support frame 4 are located at corresponding positions and rotate in coordination with them. Specifically, a seated bearing is installed at the outer end of the rotating shaft 53, and the seated bearing is fixed to the outside of the fixing plate 3. Among them, a first sealing layer 511 of rubber material is fixed on the outer circumference of the first rotating circular plate 51, which is in contact with the inner wall of the heating sleeve 1. Multiple reinforcing rods 56 are fixed between the first rotating circular plate 51 and the second rotating circular plate 52, which are evenly distributed along their circumference. The second rotating circular plate 52 is located inside the fixing ring 17, and a second sealing layer 521 of rubber material is fixed on the outer circumference of the second rotating circular plate 52, which is in contact with the inner wall of the fixing ring 17.

[0025] In this embodiment, the rotating frame 54 includes a transmission plate 541 located near and inside the first rotating plate 51, a limiting ring 542 located near and inside the second rotating plate 52, a transmission shaft 543 fixed to the outside of the transmission plate 541 and passing through the first rotating plate 51 and rotatably engaging with the first rotating plate 51 (a seated bearing is mounted on the outer end of the transmission shaft, and the seated bearing is fixed to the outside of the first rotating plate 51), and at least five connecting rods 541 located between the transmission plate 541 and the limiting ring 542 and whose two ends are fixedly connected to the corresponding positions of the transmission plate 541 and the limiting ring 542 and distributed circumferentially along the transmission plate 541. 44; It should be further explained here that the second rotating circular plate 52 has a clearance hole 522 that corresponds to the position of the limiting ring 542 and has a diameter larger than the inner diameter of the limiting ring 542 so that the tea canister 6 can be inserted into the rotating frame 54 through the clearance hole 522; Three limiting rollers 523 are evenly spaced on the inner side of the second rotating circular plate 52 at the position outside the limiting ring 542. The outer wall of the limiting roller 523 is attached to the outer wall of the limiting ring 542 so as to limit and support the limiting ring 542; A circular shaft is fixed on the inner side of the second rotating circular plate 52, and the limiting roller 523 is sleeved on the circular shaft and rotates in cooperation with it. A limiting cap is fixed on the outer end of the circular shaft to prevent the limiting roller 523 from falling off the circular shaft.

[0026] In this embodiment, a regular polygonal mounting groove 5411 is recessed at the center of the inner wall of the transmission circular plate 541, and a limiting groove 5412 is recessed on the inner wall of the mounting groove 5411; the tea caddy 6 has a cylindrical structure, and ventilation holes 61 are evenly opened on its outer wall; a mounting shaft 62 corresponding to the shape of the mounting groove 5411 is fixed on the outer side of one end of the tea caddy 6 near the mounting groove 5411, and a ball-head plunger 63 corresponding to the limiting groove 5412 is fixed on the mounting shaft 62; when the mounting shaft 62 is inserted into the mounting groove 5411... At this time, the outer end of the ball plunger 63 enters the limiting groove 5412 to limit the tea tube 6; more specifically, a lifting handle 64 is fixed on the outer wall of the tea tube 6 near the limiting ring 542; a switch door 65 is provided on the outer wall of the tea tube 6 (the arc length of the switch door 65 is greater than the arc length between two adjacent connecting rods 544; one end of the switch door 65 is hinged to the tea tube 6, and the other end is snapped onto the tea tube 6 by existing technology); and multiple stirring plates 66 extending axially are evenly fixed on the inner wall of the tea tube 6.

[0027] In this embodiment, a transmission gear ring 7 is fixed inside the heat insulation plate 2, and a transmission gear 545 is fixed at the outer end of the transmission shaft 543. The transmission gear 545 is located inside the transmission gear ring 7 and meshes with the teeth on the inner wall of the transmission gear ring 7.

[0028] In this embodiment, the support frame 4 includes an inner support ring 41 fixed to the outside of the heating jacket 1, an outer support ring 43 fixed to the outside of the inner support ring 41 by a plurality of fixing rods 42, and a support plate 45 located at the center of the outer support ring 43 and fixedly connected to the outer support ring 43 by a plurality of evenly distributed connecting plates 44. A rotating shaft 53 passes through the support plate 45 and rotates with it. Specifically, a seated bearing is installed on the rotating shaft 53, and the seated bearing is fixed on the support plate 45. The number of connecting plates 44 is the same as the number of rotating frames 54.

[0029] Open the switch door 65 of the tea caddy 6, pour the dried flower tea (such as osmanthus or jasmine) into the tea caddy 6, and spread the dried flower tea evenly to avoid piling up. The amount of tea should not exceed 1 / 2 of the volume of the tea caddy 6. Then close the switch door 65. Next, hold the lifting handle 64 and insert the tea caddy 6 from the end of the heating sleeve 1 near the support frame 4, aligning it with the clearance hole 522 on the second rotating circular plate 52, and insert it into the rotating frame 54 circumferentially. Push the tea caddy 6 until the end of its mounting shaft 62 is inserted into the mounting groove 5411 on the inner wall of the transmission circular plate 541 of the rotating frame 54. At this time, the ball-head plunger 63 (elastic protrusion) on the mounting shaft 62 is squeezed and locked into the limiting groove 5412 on the inner wall of the mounting groove 5411, thereby fixing the tea caddy 6 circumferentially to prevent it from falling off during rotation. When installing the tea caddy 6, the three limiting rollers 523 on the inner wall of the second rotating disc 52 provide radial support to the limiting ring 542, ensuring the stability of the tea caddy 6.

[0030] Water is injected into the water storage chamber 11 of the heating jacket 1 through the water injection pipe 12 (the water level covers all the electric heating wires); the power is turned on and the electric heater 16 is started to heat the water in the water storage chamber 11. The heat is transferred through the inner layer of the heating jacket to the internal air cavity of the heating jacket, forming a mild water bath heating environment. Moreover, the first sealing layer 511 and the second sealing layer 521 can reduce heat loss.

[0031] During the drying process of the material inside the tea caddy 6, the geared motor 55 is started, and the output shaft of the geared motor 55 drives the rotating shaft 53 to rotate through the coupling. The rotating shaft 53 drives the first rotating disc 51 and the second rotating disc 52, which are fixedly connected, to rotate synchronously; the first rotating disc 51 and the second rotating disc 52 drive the rotating frame 54 to rotate synchronously (i.e., revolve), and the tea caddy 6 revolves with the rotating frame 54. When the rotating frame 54 revolves, the transmission shaft 543 revolves with the rotating frame 54. Because the transmission gear 545 at the outer end of the transmission shaft 543 meshes with the transmission gear ring 7 fixed on the inner side of the heat insulation plate 2, the transmission gear 545 is forced to roll around the transmission gear ring 7, causing the transmission shaft 543 to rotate; the transmission shaft 543 drives the transmission disc 541 to rotate, and the mounting shaft 62 and the mounting groove 5411 cooperate with each other, and the transmission disc 541 further drives the tea caddy 6 to rotate synchronously. When the tea caddy 6 rotates, the stirring plate 66 continuously turns the material inside the tea caddy. In this way, the flower tea cylinder 6 rotates both around the sun and on its own axis, and with the help of the internal stirring plate 66, it continuously turns the material, so that the flower tea comes into even contact with the heat inside the heating jacket 1, which can improve the overall uniformity of drying.

[0032] During the drying process, the moisture evaporated from the flower tea is discharged into the heating jacket 1 through the vent 61 of the flower tea cylinder 6, and finally exited through the exhaust pipe 15 at the top of the heating jacket. Initially, the moisture is dense, but as drying progresses, the moisture gradually decreases and weakens. The amount of moisture can be used to determine whether the flower tea is nearing the drying end. After drying, the reduction motor 55 is turned off, the rotating part 5 stops rotating, and the flower tea cylinder 6 is pulled outward by holding the lifting handle 64. The elastic protrusion of the ball plunger 63 retracts under pressure and exits the limiting groove 5412, the mounting shaft 62 disengages from the mounting groove 5411, and the flower tea cylinder 6 is removed from the rotating frame 54 through the clearance hole 522. Open the switch door 65 of the flower tea cylinder 6 and pour the dried flower tea into the collection container.

[0033] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations.
