Description

Technical Field

[0001] The utility model relates to an open-close type comprehensive green making machine for oolong tea. Background Art

[0002] Making green tea (qing qing) is a key process in oolong tea production. It regulates water evaporation and the autolysis of tea leaves during the withering process. Mechanical forces on the leaves damage some of the leaf margin cells, promoting the oxidation, polymerization, and condensation of polyphenols, producing colored substances and promoting the formation of aromatic compounds. Making green tea consists of two steps: shaking and airing (in the oolong tea process, airing comes before shaking). During shaking, the leaf tissue vibrates, enhancing the cellular water absorption capacity and improving the transport function of the conductive tissues. Water from the stem is transported to the leaf through the veins, and aromatic substances from the stem are transferred to the leaf along with the water. Water evaporates from the leaf surface, while water-soluble substances accumulate within the leaf. As water from the stem veins penetrates the leaves, the leaves return to their swollen state after shaking, a process known as returning to life. Following shaking, the leaves enter airing, also known as resting, waiting for green, or spreading green. During the drying process, the leaves are relatively still, while water continues to evaporate from the leaves. This leads to a loss of water, while water from the stems is insufficiently replenished, causing the leaves to wilt again, a process known as withering. During the drying process, the leaves undergo a chemical process known as withering, gradually losing their green color and turning red at the edges. After 5-7 cycles of alternating shaking and drying, the leaves are considered properly dried when they exhibit a red edge (cinnabar red), a green center (or yellow-green), transparent veins, a spoon-like shape, a firm exterior, a soft feel, and a rich osmanthus (or orchid) fragrance.

[0003] The traditional process of making green tea is all done manually, which is labor-intensive and labor-intensive. In order to achieve mechanized green tea making, a Chinese patent "An Intelligent Tea Green Tea Making Machine" has been retrieved, with the announcement number CN216255221U. The machine comprises a frame, a drum, a blasting device, and an air duct. The drum is a cylindrical drum for making green tea, which is rotatably mounted on the frame, the blasting device is mounted on the frame, the blasting device is disposed adjacent to the end of the cylindrical structure of the drum, and the air duct is a circular tubular structure, one end of the air duct is mounted on the blasting device, and the main part of the air duct extends into the drum through the end of the drum. Although the air flow blown into the drum by the blasting device forms a vortex in the drum, which is conducive to uniform heating of the green leaves as a whole and uniform quality of the finished green tea, the patent requires airing after shaking the green tea, that is, the green tea leaves in the drum need to be manually taken out and spread out to dry. After spreading out, they need to be put back into the drum and shaken again. After repeated several times, the green tea making process is completed. Although the above equipment achieves mechanized shaking of green tea, the overall green tea making efficiency is still low and the manual workload is still large. Utility Model Content

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] 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 rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] The following describes some implementation structures of the present invention in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0028] The utility model discloses an oolong tea opening and closing integrated green making machine comprising a frame 1 and a drum 2 rotatably connected to the frame 1. The drum wall shape can be cylindrical or polygonal (i.e., a prism with a polygonal cross section).

[0029] At least one open window 3 is provided on the wall of the drum 2 and is arranged along the length direction of the drum. A flip plate 4 with air holes is installed on the open window 3. The flip plate 4 can flip around a rotating axis parallel to the rotation axis of the drum. The rotating axis can be a rotating axis entity, or the flip plate 4 and the drum body can be connected by a loose-leaf 19, and the rotating axis of the loose-leaf is the rotating axis of the flip plate 4.

[0030] When the turnover plate 4 is turned to close the open window, the turnover plate 4 and the rest of the cylinder wall of the drum form a complete cylinder wall surface (which can be a cylindrical wall surface or a polygonal cylinder wall surface) of the drum, and when the turnover plate 4 is turned to open, the turnover plate 4 and the lower cylinder wall of the drum form a support surface for spreading and airing the green leaves, i.e. the tea leaves are spread and aired on the turnover plate 4 and the lower cylinder wall of the drum.

[0031] In one embodiment, the drum is horizontally arranged, has one or two open windows, and the open windows are provided on the two side wall plates of the drum, and each open window is provided with a turnover plate 4 which can close the open window.

[0032] The turnover plate 4 can be an arc-shaped plate or a flat plate, and one side edge of the turnover plate 4 is connected to the outer cylinder wall of the drum through a plurality of hinges, so that the turnover plate 4 can be turned outward. Of course, the turnover plate 4 can also be rotated through a rotating shaft penetrating the two side wall plates of the turnover plate 4.

[0033] The drum 2 includes two circular side wall plates 201, a bottom plate 202 fixed between the two side wall plates, a top plate 203 fixed between the two side wall plates, and two turnover plates 4 rotatably connected to the side edges of the bottom plate. A cylindrical pipe 5 is fixed on the central part of the two side wall plates, and the length of the cylindrical pipe 5 is greater than the distance between the two side wall plates and the diameter of the cylindrical pipe 5 is less than the diameter of the drum. The cylindrical pipe 5 is provided with a plurality of air holes 501 at the position between the two side wall plates. A guide wheel 6 is arranged on the frame to support the rotation of the two end portions of the cylindrical pipe penetrating the two side wall plates. One end portion of the cylindrical pipe is driven to rotate by a belt pulley transmission mechanism 7 driven by a motor 18. A fan 8 is arranged at one end portion of the cylindrical pipe to blow air into the interior of the cylindrical pipe. The air blown by the fan 8 enters the space between the cylinder wall and the cylindrical pipe through the air holes 501. Under the action of the fan 8, the air passes through the fan 8, the interior of the cylindrical pipe 5, the air holes 501, and the space between the drum 2 and the cylindrical pipe 5 (where the tea leaves are located), thereby achieving the blowing of the tea leaves. Of course, the air inlet of the fan 8 can be provided with a hot air mechanism such as an electric heating wire to blow hot air to meet the temperature requirements of the tea-making process.

[0034] The preferred method is that the bottom plate 202, the top plate 203 and the two flip plates 4 are evenly distributed in the circumferential direction of the drum, that is, the bottom plate 202 and the top plate 203 are arranged opposite each other, and the lower sides of the two flip plates 4 are rotatably connected to the two side edges of the bottom plate 202. When flipping, the upper sides of the flip plates 4 are away from the top plate 203. After the green tea has rolled in the drum for some time, the flip plates 4 are opened, and the green tea can be spread out on the flip plates 4 or the bottom plate 202 to dry. The green tea can also be pulled into the flip plates 4 by tools to prevent the green tea from being too concentrated and stuffy, and the green tea leaves can be fully exposed to the oxygen in the air and quickly produce oxidation changes, thereby solving the problem that the current green tea making equipment causes the green tea leaves to be too concentrated and stuffy. The effect of drying the green tea leaves in this application is close to that of traditional water-screen drying, thereby improving the quality of the tea (such as promoting the water flow of the green leaves, making the red edges of the green leaves bright, improving the aroma of the tea, and the purity of the finished product), and avoiding stuffiness and dull red edges.

[0035] In order to facilitate the rotation of the green tea in the drum, a number of guide vane bars 9 parallel to the axis of rotation of the drum are provided on the inner wall surface of the drum. The guide vane bars 9 can be provided on the top plate 203, the bottom plate 202 or the flip plate 4, etc. The guide vane bars 9 can be metal bars, wooden bars or bamboo bars, etc. The cross-sectional shape of the guide vane bars 9 can be rectangular, triangular, semicircular, etc. The preferred installation position of the guide vane bars 9 is the upper side edge of the bottom plate 202 or the lower side edge of the flip plate 4 (when the machine is shut down and the flip plate 4 is about to be turned over, the green tea leaves in the flip plate 4 area will not slide directly into the bottom plate 202, reducing the workload of subsequently pulling some green tea leaves from the bottom plate area into the flip plate 4 area), as well as the side edge of the top plate.

[0036] In order to limit the flipping range of the flip plate, a side panel 10 is installed at the end edge of the flip plate, and a hook 11 is provided on the inner side of the side panel. Flanges 12 for limiting the hook are provided on the two side wall panels of the drum. When the flip plate is flipped open, the hook 11 is limited by the flange 12, so that the flip plate cannot continue to flip down.

[0037] In order to ensure that the flip plate can be firmly connected to the drum when closed, a buckling structure is provided between the free end of the flip plate and the drum when the flip plate is closed. The buckling structure includes a lug 13 with a hole installed on the free end of the flip plate and a pin 14 installed on the wall of the drum. When the flip plate is closed to open the window, the pin is inserted into the hole of the lug to achieve stable closure of the flip plate.

[0038] In order to prevent the green tea from leaking out of the drum, a blocking strip 15 is provided at the gap between the turning plate and the drum wall. The blocking strip 15 can be a plastic sheet, a wood sheet or a metal sheet.

[0039] In order to ensure that the flip plate can be favorably supported after it is flipped over, a retractable gas strut 16 is provided between the free end of the flip plate and the roller, one end of the gas strut is connected to the outside of the free end of the flip plate, and the other end of the gas strut is connected to the side wall plate of the roller. The gas strut 16 is a commercially available component, which has two working positions, namely, extending to the longest position and retracting to the shortest position. When extended to the longest position, it corresponds to the flip plate closing the open window, and when retracted to the shortest position, it corresponds to the flip plate flipping down. Since the gas strut 16 may be damaged after long-term use, the flipping amplitude of the flip plate can be limited by the aforementioned hook 11 and flange 12.

[0040] The roller 2 installed on the frame 1 of the present application needs to ensure that the turning plate does not come into contact with the ground after being turned over.

[0041] The side wall plates of the above-mentioned drum, the remaining drum walls and the turnover plate can be made of wood, bamboo, stainless steel (i.e. stainless steel plate, etc.), wire mesh (i.e. wire mesh, etc.) or rattan mesh (i.e. a mesh woven from rattan).

[0042] In order to facilitate the observation of the shaking of the green tea in the drum, several observation doors are opened on the top plate. The observation doors are equipped with cover plates that can be opened and closed. The cover plates are connected to the top plate through hinges, and the free end of the cover plate and the top plate are also connected with the aforementioned buckle structure.

[0043] The working method of the oolong tea opening and closing comprehensive green making machine of the present invention is as follows: the turning plate is turned over to open the open window, the green tea is poured into the drum, the turning plate is turned over to close the open window, the drum rotates under the action of external power (which can be a belt drive mechanism or a chain drive mechanism driven by a motor), and the drum stops rotating after rotating for a certain period of time (and it is necessary to ensure that the bottom plate is at the lowest position), the turning plate is turned over to open the open window, and the green tea is now spread on the drum wall where the turning plate and the drum are located at a lower position. At this time, the green tea drying process is being implemented. After a certain period of time, the green tea spread on the drum wall where the turning plate and the drum are located at a lower position is turned over to close the open window, and the drum starts rotating again, and this is repeated several times to complete the entire green making process. When using the green making device of the present application, there is no need to manually take out the green tea from the equipment, dry it and pour it in repeatedly, thereby greatly improving the working efficiency of green making and also being beneficial to improving the quality of tea.

[0044] The utility model discloses an oolong tea opening and closing integrated green making machine, which comprises a fan, an air duct, a transmission device, a frame and a rotatable drum connected to the frame. The drum body is divided into four arc-shaped parts (all of the materials used have a breathable function), two of which are fixed (the bottom plate and the top plate), and the other two (the flip plates) can be movably opened and closed.

[0045] When the green tea leaves need to be "heated and withered" or "shaken," the two movable arc-shaped opening and closing devices are closed to form a complete column wall surface with the rest of the drum for related operations; when the green tea leaves are in the "resting" process, the two movable (flip plate) devices are opened to be on the same plane as the bottom fixed part device (bottom plate), forming a support surface for spreading the green leaves to dry. This prevents the green leaves from being piled up too much and allows them to be evenly and quickly exposed to oxygen in the air, producing the oxidation changes required for tea making. This effectively solves the drawback of the old-fashioned green tea making machine where the green leaves are piled up and stuffy, and achieves the effect of traditional water-screening green tea drying. At the same time, it can further promote the water flow of the green tea leaves, make the edges of the green leaves bright and vivid red, avoid the generation of stuffy tea leaves and dull red edges, and further improve the efficiency of green tea making and the quality of tea.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are welcome.
