DETAILED DESCRIPTION

[0028] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0029] This embodiment provides a method for processing Maofeng tea, which specifically comprises the following steps: S1. Fresh leaf spreading: Spread the picked fresh tea leaves on a spreading machine for spreading. The spreading temperature is controlled at 20-26°C and the spreading time is controlled at 3-4h.

[0031] The Maofeng tea processing method uses a rehumidification step so that the multi-layer mesh belt rehumidification machine can make the rehumidification effect of the tea more uniform, so as to control the moisture content of the tea, thereby ensuring the uniformity of the moisture inside the tea, so as to ensure the uniformity of subsequent drying; in the drying process of the method, the initial drying is carried out by high-temperature hair pulling fire, which can promote the aroma of the tea, and the secondary drying adopts a low-temperature slow drying method, which further enhances the aroma of the tea while ensuring the moisture content of the tea, so that the quality of the prepared tea is more superior.

[0032] The present invention also provides a Maofeng tea processing device, which is used for performing the drying operation in the above steps.

[0033] Combination Figure 1-8 As shown, a Maofeng tea processing device in this embodiment includes a drying box 100 with an upper opening, and a detachable box cover 110 is provided at the upper opening of the drying box 100. The box cover 110 is installed on the drying box 100 for installing a filter frame 200 with tea leaves laid flat in the drying box 100; A hot air inlet assembly is provided in the drying box 100 and at the bottom thereof, and a broken tea collecting assembly is also provided in the drying box 100 and is covered above the hot air inlet assembly, the broken tea collecting assembly comprises a truncated cone-shaped collecting cover 210, the outer edge of the collecting cover 210 is bent to form a broken tea collecting portion 211 for collecting broken tea, a turning assembly for turning the tea leaves in the filter frame 200 is provided at the middle position of the collecting cover 210, the turning assembly comprises a rotatable air duct 220 whose lower end is connected to the hot air inlet assembly, an air jet pipe 221 connected to the air duct 220 is provided at the upper end portion of the air duct 220 along the radial direction of the filter frame 200, and spray holes are distributed on the air jet pipe 221, a first knocking assembly for knocking the filter frame 200 is also provided in the air duct 220, a switching assembly is also provided in the hot air inlet assembly, and the switching assembly is used to allow hot air to enter the air duct 220, and a second knocking assembly for knocking the collecting cover 210 is also provided in the collecting cover 210.

[0034] In actual use of this embodiment, the upper opening of the drying box 100 extends outward to form a mounting ring 102, and the outer edge of the box cover 110 overlaps the mounting ring 102, and the two are connected by bolts to realize the disassembly and assembly of the box cover 110 at the upper opening of the drying box 100; The inner wall of the drying box 100 is provided with a lap ring 201 for lap-joining the filter frame 200 along its circumference. The filter frame 200 includes an annular frame and a filter screen provided at its lower end. The tea leaves are spread on the filter screen. The air permeability of the filter screen can be used to dry the tea leaves, and the broken tea leaves in the tea leaves can be filtered by the filter screen. When the box cover 110 is installed on the drying box 100, it can preferably press-fit the filter frame 200 to realize the installation of the filter frame 200 in the drying box 100. In this embodiment, Figure 2 As shown, the broken tea collection assembly can be lifted and lowered below the filter frame 200, wherein the collection cover 210 is in a truncated cone shape, which can guide the broken tea filtered by the filter frame 200 and falling thereon to the broken tea collection part 211 for collection, and the outer wall of the broken tea collection part 211 slides and fits the inner wall of the drying box 100 to ensure the effect of collecting the broken tea and prevent the broken tea from falling into the drying box 100 below it; in actual use, a discharge slot (not shown in the figure) is provided on the outer wall of the drying box 100 corresponding to the broken tea collection part 211, and a side plate (not shown in the figure) is provided at the discharge slot by screws, thereby, when the broken tea collection assembly is lowered to the lowest position, the broken tea collected by the broken tea collection part can be discharged better by opening the side plate; The hot air inlet assembly is located below the broken tea collection assembly, and is used to deliver hot air into the drying box 100. Specifically, the collection cover 210 is provided with air holes, and the box cover 110 is provided with an air outlet pipe 111, so that the hot air entering the drying box 100 from the hot air inlet assembly can flow upward through the air holes, and be discharged from the drying box 100 through the air outlet pipe 111 through the filter frame 200, thereby drying the tea leaves. Among them, through the arrangement of the air duct 220, the air jet pipe 221, the spray hole and the switching component, when it is necessary to use the flipping component to flip the tea leaves in the filter frame 200 in actual use, the switching component can switch the hot air inlet component so that the hot air discharged by it can enter the air duct 220 and be sprayed out through the air jet pipe 221 and the spray hole, so that it can blow the tea leaves to flip them. Among them, as the air duct 220 rotates, the positions of the air jet pipe 221 and the spray hole are changed, so that the tea leaves laid in the filter frame 200 can be flipped more evenly; when it is not necessary to flip the tea leaves, the switching component can switch the hot air inlet component to stop supplying air to the air duct 220, so that it can transport hot air to the drying box 100 for drying. Among them, by setting the first knocking component, when the hot air in the air duct 220 flows to turn the tea leaves in actual use, the hot air flow can drive the first knocking component to knock the filter frame 200, causing the filter frame 200 to vibrate, thereby improving its filtering effect on broken tea leaves; Among them, through the setting of the second knocking component, in actual use, when the hot air flow in the air duct 220 turns the tea leaves, the second knocking component can knock on the collection cover 210, so as to better make the broken tea on it fall into the broken tea collection part 211, so as to promote the collection of broken tea.

[0035] Combination Figure 6 As shown, in this embodiment, the hot air inlet assembly includes an air inlet box 230, and an air cavity 231 is provided in the air inlet box 230. The air inlet pipe 120 for conveying hot air into the air cavity 231 is evenly distributed along the circumference of the drying box 100; The switching component includes a first bracket 250 which is raised and lowered in the air cavity 231 by a spring 240, a fixing plate 610 is provided on the upper plate surface of the first bracket 250 through a connecting column 601, a first leakage hole 611 is distributed on the fixing plate 610, and a second leakage hole 621 which is offset from the first leakage hole 611 is distributed on the upper side wall of the air cavity 231, and the spring 240 drives the first bracket 250 to move upward so that the fixing plate 610 fits the upper side wall of the air cavity 231 to close the second leakage hole 621.

[0036] In this embodiment, the air inlet box 230 is fixedly mounted on the bottom wall of the drying box 100, and can preferably deliver hot air to the air cavity 231 through the arrangement of multiple air inlet pipes 120. Specifically, the air inlet pipes 120 are used to connect to the hot air furnace to deliver hot air to the air cavity 231, wherein the temperature of the hot air is controlled according to the drying temperature; Among them, a spring mounting sleeve is provided at the center position of the lower side surface of the first bracket 250, the upper end of the spring 240 is located in the spring mounting sleeve, and the lower end is abutted against the bottom wall of the air cavity 231. The spring 240 is used to push the first bracket 250 upward, so that the fixing plate 610 can fit the upper side wall of the air cavity 231. Since the first leakage hole 611 and the second leakage hole 621 are misaligned, the second leakage hole 621 is closed. At this time, the broken tea collection component is located at the highest point, and the lower end of the air duct 220 extends into the air cavity 231 and does not fit the first bracket 250, that is, the hot air entering the air cavity 231 from the air inlet pipe 120 can enter the air duct 220 through the fixing plate 610 and the first bracket 250, so that the hot air enters the jet pipe 221 and is ejected through the jet hole to turn the tea leaves in the filter frame 200. It should be noted that, in the present embodiment, the cross-sectional area of ​​the air duct 220 is much smaller than the sum of the areas of the second leakage holes 621. Thus, when the air intake of the air intake pipe 120 remains unchanged, the flow rate of the hot air in the air cavity 231 entering the air duct 220, the jet pipe 221 and the jetting hole to eject the hot air increases. Thus, the airflow ejected from the jetting hole can blow the tea leaves in the filter frame 200 to flip.

[0037] When the broken tea collecting assembly descends, the lower end of the air duct 220 moves downward, so that it abuts against the first bracket 250, thereby closing the air duct 220. At the same time, it continues to push the first bracket 250 downward to drive the fixing plate 610 to separate from the upper side wall of the air cavity 231, thereby opening the second leakage hole 621. At this time, the hot air entering the air cavity 231 can enter the drying box 100 through the second leakage hole 621. There are multiple second leakage holes 621 evenly distributed on the upper side wall of the air cavity 231, so that the hot air in the air cavity 231 can enter the drying box 100 more evenly, so that the tea leaves are dried more evenly. Specifically, in order to prevent the lower end of the air duct 220 from being separated from the air inlet box 230 during the lifting process, an extension tube 631 for the air duct 220 to extend into is provided at the upper end of the air inlet box 230 .

[0038] In this embodiment, combined with Figure 3 and Figure 4 As shown, a second bracket 212 is provided on the inner side of the collecting hood 210 and at the lower end portion, the lower end of the air duct 220 passes through the second bracket 212 and extends into the air cavity 231, a driven gear 410 is provided on the outer wall of the air duct 220 between the collecting hood 210 and the second bracket 212, and a driving gear for cooperating with the driven gear 410 is provided on the second bracket 212 through the motor 310. The collecting hood 210 and the air duct 220 are lowered to drive the lower end of the air duct 220 to abut against the second bracket 212, and drive the fixing plate 610 to move downward to realize the opening of the second leakage hole 621.

[0039] In this embodiment, the second bracket 212 is fixedly installed at the inner lower end portion of the collecting cover 210, and the air duct 220 is rotatably installed on the second bracket 212 through a bearing, thereby realizing the rotatable setting of the air duct 220; wherein, through the setting of the motor 310, the driven gear 410 and the driving gear, the motor 310 can better drive the air duct 220 to rotate, thereby, when the spray hole sprays air, the rotation of the air duct 220 can drive it to rotate, so that the tea leaves are evenly turned over.

[0040] In actual use, in order to better realize the lifting and lowering of the collection hood 210 and the air duct 220, a support leg 101 for supporting them is provided on the lower end surface of the drying box 100, so that the cylinder 130 is evenly distributed along its circumference on the lower end surface of the drying box 100, and the output shaft of the cylinder 130 passes through the bottom wall of the drying box 100 and is connected to the broken tea collection part 211, thereby, the broken tea collection component can be driven to rise and fall through the cylinder 130.

[0041] In this embodiment, combined with Figure 5-7As shown, the first knocking assembly includes a tube body 510 detachably installed in the air duct 220, a driving chamber 511 is provided in the tube body 510, a rotatable rotating column 520 is provided at the lower end of the driving chamber 511, and a lifting cylinder 530 covering the outside of the rotating column 520 is also provided in the driving chamber 511, and a sliding groove 701 connected end to end and in a wave shape is arranged on the outer wall of the rotating column 520 along its circumference, and a sliding column 721 sliding in the sliding groove 701 is relatively provided on the inner wall of the lifting cylinder 530, and a push rod 531 extending through the upper end of the tube body 510 is provided at the upper end of the lifting cylinder 530, and a sliding groove 532 is provided on the side wall of the push rod 531 along its circumference, and a sliding block sliding in the sliding groove 532 is provided on the tube body 510, and the rotation of the rotating column 520 is used to drive the sliding column 721 to slide in the sliding groove 701 to realize the push rod 531 lifting the filter frame 200.

[0042] In this embodiment, the air duct 220 is opened at both ends, and the upper end opening thereof extends outward to form a flange portion 401. The upper end of the tube body 510 extends outward to form a mounting portion 731 that matches the flange portion 401. The mounting portion 731 is fixed to the flange portion 401 by bolts, so that the tube body 510 is fixedly installed in the air duct 220. The slide groove 532 and the slider are arranged in cooperation, so that the lifting cylinder 530 is limited so that it cannot rotate in the circumferential direction. The sliding groove 701 and the sliding column 721 are arranged in cooperation, so that the rotating column 520 can rotate to enable the push rod 531 to extend out of the air duct 220 at intervals, thereby lifting the filter screen of the filter screen frame 200, so that the filter screen vibrates, thereby promoting its filtering of broken tea. In this embodiment, a rotating shaft 521 is disposed at the lower end of the rotating column 520 and penetrates through the tube body 510 and extends into the air duct 220 . An impeller 710 is disposed at the lower end of the rotating shaft 521 .

[0043] In this embodiment, by disposing the impeller 710 , the hot air flowing in the air duct 220 can drive the impeller 710 to rotate, thereby driving the rotating column 520 to rotate, thereby achieving the interval lifting of the jack 531 .

[0044] In this embodiment, combined with Figure 8 As shown, the second knocking assembly includes a mounting seat 810 on the second bracket 212 uniformly distributed along the circumference of the air duct 220, and a knocking rod 811 is provided on the mounting seat 810 through a torsion spring rotation. The torsion spring is used to drive the upper end of the knocking rod 811 to abut against the inner wall of the collecting cover 210 and the lower end to abut against the upper end surface of the driven gear 410. A lifting block 820 is provided on the upper end surface of the driven gear 410, and a guide bevel 821 is provided on one side wall of the lifting block 820. The driven gear 410 is rotated to drive the lower end of the knocking rod 811 to slide along the guide bevel 821 into the lifting block 820 and slide onto the driven gear 410, so that the knocking rod 811 knocks the collecting cover 210.

[0045] In actual use of this embodiment, the mounting seat 810 is mounted on a mounting ring 800, and the mounting ring 800 is fixedly mounted on the second bracket 212 by screws. Through the above structure, in actual use, the rotation of the air duct 220 can drive the lifting block 820 to rotate accordingly, and then during its movement, the lower end of the knocking rod 811 slides onto the lifting block 820 along the guide inclined surface 821 and cooperates with the torsion spring to slide to the upper end surface of the driven gear 410, so that the upper end of the knocking rod 811 can knock the collection cover 210, thereby causing the collection cover 210 to vibrate, so as to promote the broken leaves on it to slide into the broken leaf collection part 211 for collection; Among them, there are multiple knocking rods 811 arranged along the circumference of the air duct 220, so that the driven gear 410 can drive the knocking rods 811 to knock the collection cover 210 in sequence during the rotation, so that the collection cover 210 is knocked more evenly and its vibration effect is better.
