Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a tea rolling and drying system. Background Art

[0002] Tencha, the raw material for matcha, is made from fresh leaves that are covered before picking, through a process of withering, drying, and separating the stems and leaves. After grinding, the tea becomes matcha. While specialized equipment such as steam withering machines and furnaces for tencha have been developed in China, drying equipment for tencha remains a niche. Currently, improving the quality of tencha has become a pressing need for most domestic tencha companies. Only by developing tencha drying equipment tailored to the quality and style of Chinese tea can the quality of my country's tencha products be continuously improved, meeting the growing consumer demand for mid-range and high-end matcha.

[0003] A published Chinese patent application, Publication No. CN215063540U, titled "Tea Rolling Equipment with Drying Structure," describes a prior art device comprising a housing, a preheating device, a drying device, and a drive mechanism. The preheating device is mounted within the housing; the drying device is fixed to a side wall of the housing; and the drive mechanism is mounted on one side of the drying device. During use, tea leaves to be dried are poured into the conveyor opening and preheated on conveyor belts staggered vertically. Air from a blower at the bottom of the housing is then blown through a hot air blower to preheat the tea leaves on the conveyor belt. The evaporated water vapor escapes through vents in the housing wall, achieving a single preheating operation and enhancing the taste of the dried tea leaves. The preheated tea leaves are then conveyed by the conveyor belt to the dryer. The motor drives the drying drum's rotating shaft, which in turn rotates the drum. This, in turn, rotates a stirring baffle within the drum, ensuring thorough stirring and uniform drying. While this prior art device can achieve tea rolling drying, it does have certain limitations in its implementation.

[0004] This prior art utilizes a motor to rotate the rotating shaft of the drying barrel, thereby rotating the drying barrel and the stirring baffle inside the drying barrel, thereby fully stirring the tea leaves and evenly drying them. However, this prior art utilizes a stirring drying method to dry the rolled tea leaves, and some rolled tea leaves are easily broken by the rotating stirring. This prior art fails to ensure the integrity of the rolled tea leaves and instead reduces their overall quality. Therefore, this prior art fails to dry the rolled tea leaves while maintaining their overall quality. Utility Model Content

[0015] (3) Beneficial effects

[0016] The utility model provides a tea rolling drying system, which has the following beneficial effects:

[0017] 1. This rolling tea drying system, through the coordinated arrangement of a feeding component, an exhaust component, an air supply component, and a drying box, enables the rolling tea drying system to effectively dry the rolling tea without damaging it. Fresh air is drawn in by a blower and heated by a hot air furnace to form hot air. The hot air flows into an air guide hood, where the air pressure increases. When the air pressure in the air guide hood reaches a certain threshold, the hot air pressure pushes open the air equalization components at each air guide port and flows into the drying box. The hot air simultaneously flows through multiple longitudinally arranged air guide ports into the drying box, drying the rolling tea on the conveying mesh plate in the drying box. The hot air flows laterally and blows the rolling tea on the conveying mesh plate, thereby effectively drying the rolling tea. Compared with existing technologies, this system can dry the rolling tea while ensuring its overall quality and avoiding damage to the tea.

[0018] 2. This rolling tea drying system, through the provision of a feeding component, can better ensure that the tea leaves are evenly spread. Driven by a motor, the feeding belt rotates, conveying the rolling tea toward the side of the drying box feed port. The rolling tea falls through the feed port onto the conveyor mesh of the drying box, thereby evenly spreading the rolling tea on the conveyor mesh. This better prevents tea leaves from being stuck due to excessive thickness and thus avoiding mechanical failure.

[0019] 3. This rolling tea drying system uses a dehumidification fan installed in the exhaust hood. Dehumidification fans are used at the rear and upper parts of the drying chamber to assist in exhaust. This prevents the rolling tea from turning yellow inside the drying chamber, allowing for more thorough and even tea flow, thus preserving its original green color. Traditional dryers, however, have strong wind pressure at the front and gradually weaken at the back, resulting in uneven temperatures inside the chamber, which can cause the tea leaves to turn yellow.

[0020] 4. This tea drying system passes the air inlet pipe through the exhaust pipe body, and the drying box discharges hot air with residual temperature through the exhaust pipe. The hot air heats the air inlet pipe during the discharge process, thereby preheating the fresh air in the air inlet pipe, thereby realizing heat recovery, avoiding heat energy loss, and achieving the purpose of effective energy saving.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication 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. Obviously, the embodiments described are only some of the embodiments of this utility model, and not all of them.

[0032] See also Figures 1 to 7 The utility model provides a technical solution: a rolling tea drying system for drying rolling tea, comprising a drying box 1, wherein a conveying mesh plate for carrying rolling tea is provided inside the drying box 1.

[0033] The conveyor mesh is a conveyor belt, such as that used in the tea rolling equipment with a drying structure disclosed in Publication No. CN215063540U. Multiple conveyor meshes are arranged longitudinally within the drying oven, with adjacent conveyor meshes conveying tea in opposite directions. The tea on the upper conveyor mesh moves laterally and then falls onto the lower conveyor mesh.

[0034] A rolled tea drying system also includes a feeding component, an exhaust component, and an air supply component. A feeding port is provided on the top wall of the drying box 1, and a discharging port 19 is provided on the bottom wall of the drying box 1.

[0035] The feeding component is used to convey the rolled tea into the drying box 1, and the rolled tea falls through the feeding port onto the conveying mesh plate inside the drying box 1. The air supply component is used to convey hot air into the drying box 1. The exhaust component is used to exhaust the hot and humid air inside the drying box 1.

[0036] The air supply components include a blower 7, a hot air stove 8, an air guide cover 10, and an air inlet pipe 17. The blower 7 and the hot air stove 8 are fixedly installed at the bottom of the drying box 1. A filter cartridge 18 is fixedly installed at the inlet end of the air inlet pipe 17. The outflow end of the air inlet pipe 17 is connected with the inflow end of the blower 7, and the outflow end of the blower 7 is connected with the furnace cavity of the hot air stove 8. The furnace cavity of the hot air stove 8 is connected with the air guide cover 10. The air guide cover 10 is fixedly installed on one side wall of the drying box 1. A plurality of air guide ports 11 connected with the interior of the drying box 1 are opened on the air guide cover 10, and the air guide ports 11 are arranged in sequence longitudinally. An air equalization component is provided on the air guide cover 10 and at each air guide port 11.

[0037] The blower 7 draws fresh air through the air inlet pipe 17, and the hot air furnace 8 heats the fresh air to form hot air. The hot air flows into the air guide cover 10, and the wind pressure in the air guide cover 10 increases. When the wind pressure in the air guide cover 10 reaches a certain threshold, the hot air pressure pushes open each air equalization component and flows into the drying box 1, and the hot air dries the rolled tea on the conveying mesh.

[0038] Filter cartridge 18 is used to filter the fresh air entering air inlet duct 17, reducing dust pollution and the risk of microbial contamination during the production process, thereby improving the safety of the rolled tea. Blower 7 draws fresh air through air inlet duct 17, which then flows into the cavity of hot air furnace 8, where it is heated to form hot air. This hot air then flows through multiple longitudinally arranged air ducts into the drying oven, drying the rolled tea on the conveyor screen within the drying oven. The hot air flows laterally, blowing over the rolled tea on the conveyor screen, effectively drying the rolled tea.

[0039] Specifically, the feeding component is fixedly mounted on an upper side wall of the drying oven 1, with its discharge end located above the feed inlet of the drying oven 1. The feeding component comprises a feeding hopper 2, a motor 3, a feeding belt 6, and two rotating shafts 4. The two rotating shafts 4 are rotatably mounted on the feeding hopper 2. The motor 3 is fixedly mounted on the outer side wall of the feeding hopper 2, with the output shaft end of the motor 3 coaxially fixedly connected to one end of one of the rotating shafts 4. The feeding belt 6 is tightly wound around the two rotating shafts 4 in a ring shape.

[0040] The motor 3 is used to drive a rotating shaft 4 to rotate, which in turn drives the feeding belt 6 to rotate. That is, the feeding belt 6 rotates around the two rotating shafts 4. During the rotation process, the feeding belt 6 moves the rolled tea in the feeding hopper 2 to the feeding port. After the rolled tea leaves the feeding belt 6, it falls through the feeding port and falls onto the conveying mesh, that is, it is spread flat on the conveying mesh.

[0041] Specifically, multiple protrusions 5 are fixedly attached to the outer walls of each end of the rotating shaft 4. These protrusions 5 support the edges of the feeding belt 6, creating a raised shape relative to the center. The outer surface of the feeding belt 6 is provided with numerous grooves. The motor 3 drives the feeding belt 6 via the rotating shaft 4, which conveys the tea leaves from the feeding hopper 2 into the drying oven 1.

[0042] The outer surface of the feeding belt 6 is provided with a plurality of grooves adapted to the rolled tea leaves. The rolled tea leaves in the upper hopper 2 are accommodated in the grooves, and the feeding belt 6 can effectively push the rolled tea leaves to move when it moves, that is, it can effectively transport the rolled tea leaves.

[0043] Specifically, the exhaust assembly is fixedly mounted on the drying oven 1 and communicates with the interior of the drying oven 1. It includes an exhaust duct 16, which is fixedly mounted on the outer wall of the drying oven 1 and communicates with the interior. An air inlet duct 17 extends through the body of the exhaust duct 16. Hot air with residual heat is discharged from the drying oven 1 through the exhaust duct 16. During the discharge process, the hot air heats the air inlet duct 17, thereby preheating the fresh air in the air inlet duct 17.

[0044] Among them, by passing the air inlet pipe 17 through the exhaust pipe 16, the drying box 1 discharges hot and humid air with residual temperature through the exhaust pipe 16. The hot and humid air heats the air inlet pipe 17 during the discharge process, thereby preheating the fresh air in the air inlet pipe 17, thereby realizing heat recovery, avoiding heat energy loss, and achieving the purpose of effective energy saving.

[0045] Specifically, the exhaust component also includes an exhaust hood 15, which is fixedly installed on the top of the drying box 1 and the two are connected. One end of the exhaust pipe 16 is fixedly installed on the exhaust hood 15 and the two are connected. A dehumidification fan is fixedly installed in the exhaust hood 15.

[0046] Exhaust hood 15 and exhaust duct 16 are both used to exhaust the hot, humid air within drying oven 1. A dehumidification fan accelerates the exhaust of hot, humid air within drying oven 1, enhancing airflow. By installing a dehumidification fan within exhaust hood 15, and thereby assisting exhaust at the rear and upper portions of drying oven 1, the tea leaves are prevented from becoming stale and yellowing within drying oven 1. This allows for more thorough and even tea leaf drainage, preserving their original green color.

[0047] Specifically, a connecting pipe 9 communicating with the furnace cavity is fixedly mounted on the hot blast furnace 8, and one end of the connecting pipe 9 away from the hot blast furnace 8 is communicated with an air guide cover 10. A filter plate 12 is provided inside the air guide cover 10.

[0048] The connecting pipe 9 is used to guide the flow of air. The filter plate 12 is used to perform secondary filtration on the fresh air (i.e., the hot air), thereby reducing dust pollution during the production process, reducing the risk of microbial contamination, and improving the safety index of the tea rolling process.

[0049] More specifically, the wind equalizing assembly includes two opposing baffles 14 , which are hinged to the air guide cover 10 via a fixed shaft 13 , and a torsion spring is provided at the hinge between the baffle 14 and the air guide cover 10 .

[0050] After the blower 7 is started, air is drawn into the air inlet pipe 17, heated by the hot air furnace 8, and then blown into the air guide cover 10. The hot air evenly fills the air guide cover 10. At the same time, due to the obstruction of the baffle 14 in the air guide port 11, the hot air is blocked in the air guide cover 10, the wind pressure in the air guide cover 10 increases, and the air pressure in the air guide cover 10 gradually stabilizes and balances. When the air pressure reaches a certain value, the air pressure simultaneously pushes the baffles 14 in multiple air guide ports 11 to overcome the force of the torsion spring, causing the baffles 14 to open into the drying box 1, allowing hot air to enter each air guide port 11 at the same time, preventing hot air from entering the drying box 1 only from the air guide port 11 corresponding to the connecting pipe 9, thereby preventing uneven drying.

[0051] At the same time, due to the inclination angle of the baffle 14, the ventilation area of ​​the air guide port 11 is reduced, and the pressure in the air guide cover 10 is relatively high, so that the hot air enters the drying box 1 at a faster speed, and the hot air can directly pass through the entire drying box 1, so that the temperature of the drying box 1 near the air guide port 11 and away from the air guide port 11 remains consistent, avoiding the heat caused by slow wind speed being completely lost near the air guide port 11, and the heat away from the air guide port 11 being too low, resulting in uneven drying, further improving the drying effect.

[0052] After the hot air enters the drying box 1 to dry the ground tea, it enters the exhaust duct 16 through the exhaust hood 15. A section of the air inlet duct 17 is located inside the exhaust duct 16. The residual heat of the exhaust gas in the exhaust duct 16 can be used to preheat the new air in the air inlet duct 17, so that the air can be quickly heated to the specified temperature when entering the hot air furnace 8, thereby improving the drying efficiency and helping to reduce the energy consumption of the hot air furnace 8 and reducing energy consumption.

[0053] Finally, the rolled tea moves to the discharge port 19 through the circulating mesh plate to complete drying. The dried rolled tea can be directly discharged from the discharge port 19 into a pre-placed rolled tea receiving container.

[0054] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
