Description

Technical Field

[0001] The invention relates to tea production equipment with a stir-frying function, and belongs to the technical field of tea stir-frying. Background Art

[0002] After tea leaves are picked, enzymes (such as polyphenol oxidase and peroxidase) within the leaves continue to be active, catalyzing the oxidation of tea polyphenols and other components, causing the leaves to brown and ferment. Stir-frying at high temperatures quickly destroys the enzyme structure, rendering it inactive and thus preventing excessive oxidation: This prevents the tea from developing a bitter or fermented taste due to enzymatic reactions. Stir-frying allows the large amount of low-boiling-point grassy substances in the fresh leaves to evaporate with the water. At the same time, high temperatures promote the release of high-boiling-point aroma components (such as floral substances like benzyl alcohol and phenylethyl alcohol, as well as terpenes), creating the tea's fresh, floral, or cooked aroma.

[0003] In the existing method of stir-frying tea leaves, the tea leaves are placed in a tea-frying pot, the heating temperature and stir-frying time are set by a control system, the electromagnetic heating coil starts working, and the heat generated is quickly transferred to the tea-frying pot to heat and stir-fry the tea leaves. During the stir-frying process, the tea leaves can be turned manually or mechanically as needed to ensure that the tea leaves are heated evenly. Since the tea leaves are inside the stir-frying pot, after the stir-frying is completed, the pot body needs to be tilted as a whole to discharge the stir-fried tea leaves. Since the pot body is heavy, it is inconvenient to take out the tea leaves. For this reason, we propose a tea production equipment with a stir-frying function. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a tea production equipment with a stir-frying function, which solves the problem in the prior art that after the tea leaves are stir-fried, the entire pot body needs to be tilted to discharge the stir-fried tea leaves, and the tea leaves are inconvenient to take out due to the heavy pot body.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A tea production equipment with a stir-frying function, comprising a support frame and a stir-frying pot, a discharge port being provided at the bottom of the stir-frying pot, a sealing platform being plugged into the inside of the discharge port, a rotating shaft being rotatably connected to the inside of the sealing platform, a driving component that can control the rotation of the rotating shaft being fixedly connected to one end of the rotating shaft, a stir-frying component being sleeved on the outer surface of the rotating shaft, the driving component being installed inside the mounting frame, a moving component that can control the mounting frame to move up and down being fixedly installed on the mounting frame, and a spreading component that can spread the tea leaves is provided under the stir-frying pot.

[0006] By adopting the above technical solution, when frying the tea leaves, the staff can pour the tea leaves into the stir-fry pot, and then start the servo motor to control the rotation shaft to rotate, so that the stir-fry rack can rotate inside the stir-fry pot and stir-fry the tea leaves inside the stir-fry pot. When the stir-frying is completed, the staff can start the servo cooling fan and the electric push rod, and the electric push rod drives the mounting rack to move downward, so that the rotation shaft can drive the sealing table to move downward, and the sealing table moves out from the inside of the discharge port, so that the tea leaves inside the stir-fry pot can be discharged from the discharge port, and the tea leaves are taken out more conveniently. In addition, in the process of the mounting rack moving downward, the rack can be driven to move downward, and the gear can be controlled to reverse, so that the rotating roller rotates in the opposite direction, and the conveyor belt also rotates in the opposite direction. Since the conveyor belt continues to run, tea leaves fall from the inside of the stir-fry pot. The tea leaves dropped from the conveyor belt can fall on different positions of the conveyor belt, and due to the setting of the spreading plate, the tea leaves on the conveyor belt can be spread so that the tea leaves can be spread more evenly on the conveyor belt, and the cooling fan continuously blows air on the conveyor belt to cool the spread tea leaves. When the tea leaves need to be fried again, the staff can start the electric push rod, which can drive the mounting frame to move upward, so that the rotating shaft drives the sealing table to move upward, and the sealing table can seal the discharge port. At this time, since the rack moves upward, the gear can rotate forward, and the conveyor belt can rotate forward. During the forward rotation of the conveyor belt, the tea leaves can be driven to move to the right. During the movement, the tea leaves can fall into the tea collection box below the conveyor belt in turn, making tea collection more convenient.

[0007] The present invention is further configured as follows: the driving assembly includes a servo motor, the servo motor is fixedly connected to the top end of the rotating shaft, and the servo motor is fixedly installed inside the mounting frame.

[0008] By adopting the above technical solution, the servo motor can provide rotational power to rotate the rotating shaft, thereby controlling the stir-fry rack to rotate, stir-frying the tea leaves inside the stir-fry pan, and making the tea leaves heated more evenly.

[0009] The present invention is further configured as follows: the stir-fry assembly includes a fixed tube sleeved on the outer surface of the rotating shaft, the outer surface of the fixed tube is fixedly connected to the stir-fry rack, the outer surface of the rotating shaft is fixedly connected to the baffle, and the fixed tube and the baffle are connected by a support spring.

[0010] The present invention is further configured as follows: a limiting protrusion is fixedly connected to the outer surface of the rotating shaft, a limiting groove is provided inside the fixing tube, and the limiting protrusion is inserted into the limiting groove.

[0011] By adopting the above technical solution, due to the arrangement of the limiting protrusion and the limiting groove, the fixed tube and the rotating shaft can move in the up and down directions but cannot rotate relative to each other. This ensures that when the rotating shaft rotates, the fixed tube can be controlled to rotate. When discharging materials, the stir-fry rack is blocked by the bottom of the stir-fry pan, so that the stir-fry rack remains inside the stir-fry pan, and as the rotating shaft continues to move downward, the support spring can be compressed to ensure that the rotating shaft moves downward without being blocked.

[0012] The present invention is further configured as follows: the moving assembly includes an electric push rod, one end of the electric push rod is fixedly connected to the mounting frame, the other end of the electric push rod is fixedly connected to the fixing frame, and both ends of the fixing frame are fixedly connected to the support frame.

[0013] By adopting the above technical solution, the electric push rod can drive the mounting frame to move downward, thereby facilitating the discharge of tea leaves.

[0014] The present invention is further configured as follows: the paving assembly includes two rotating rollers, the two rotating rollers are connected by a conveyor belt, the conveyor belt is arranged below the discharge port, and the two rotating rollers are installed inside the bracket through bearings.

[0015] The present invention is further configured as follows: one end of one of the rotating rollers is fixedly connected to a gear, the outer surface of the gear is meshedly connected to a rack, and the rack is fixedly connected to the mounting frame via a reinforcing rod.

[0016] By adopting the above technical solution, the rack moves downward, which can drive the gear to rotate in the opposite direction, and the conveyor belt runs in the opposite direction, which is beneficial to the spreading of tea leaves. The rack moves upward, which can drive the gear to rotate in the forward direction, and drive the conveyor belt to run in the forward direction, which is beneficial to the collection of tea leaves.

[0017] The present invention is further configured as follows: a paving plate is fixedly connected to the lower surface of the sealing platform, and a plurality of through holes are provided on the paving plate.

[0018] By adopting the above technical solution, the spreading plate can scrape and level the tea leaves piled up on the conveyor belt, ensuring that the tea leaves are spread more evenly and have a better cooling effect on the tea leaves.

[0019] The present invention is further configured as follows: the support frame and the bracket are both fixedly mounted on the upper surface of the bottom frame, and a tea collection box is placed on the bottom frame.

[0020] By adopting the above technical solution, the tea collection box can collect the cooled tea leaves.

[0021] The present invention is further configured as follows: a fan frame is installed on the support frame, and a cooling fan is fixedly installed on the fan frame.

[0022] By adopting the above technical solution, the wind blown by the cooling fan can take away the heat on the surface of the tea leaves, so that the tea leaves are cooled faster and are convenient for subsequent collection of the tea leaves.

[0023] The beneficial effects of the present invention are:

[0024] When frying the tea leaves, the staff can pour the tea leaves into the stir-fry pan, and then start the servo motor to control the rotation shaft to rotate, so that the stir-fry rack can rotate inside the stir-fry pan to stir-fry the tea leaves inside the stir-fry pan. When the stir-frying is completed, the staff can start the servo cooling fan and the electric push rod, and the electric push rod drives the mounting rack to move downward, and the rotation shaft can drive the sealing table to move downward, and the sealing table is moved out from the inside of the discharge port, so that the tea leaves inside the stir-fry pan can be discharged from the discharge port, and it is more convenient to take out the tea leaves.

[0025] During the downward movement of the mounting frame, the rack can be driven to move downward, and the gear can be controlled to reverse, so that the rotating roller rotates in the opposite direction and the conveyor belt also rotates in the opposite direction. Since the conveyor belt continues to run, the tea leaves falling from the inside of the stir-fry pot can fall on different positions of the conveyor belt, and due to the setting of the spreading plate, the tea leaves on the conveyor belt can be spread so that the tea leaves can be spread more evenly on the conveyor belt, and the cooling fan continuously blows air on the conveyor belt to cool the spread tea leaves.

[0026] When it is necessary to fry the tea leaves again, the staff can start the electric push rod, which can drive the mounting frame to move upward, so that the rotating shaft drives the sealing platform to move upward, and the sealing platform can seal the discharge port. At this time, since the rack moves upward, the gear can rotate forward, and the conveyor belt can rotate forward. During the forward rotation of the conveyor belt, the tea leaves can be driven to move to the right. During the movement, the tea leaves can fall into the tea collection box below the conveyor belt in turn, making tea collection more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further explained below with reference to specific illustrations.

[0035] Example 1

[0036] like Figures 1 to 5 As shown, a tea production device with a stir-frying function includes a support frame 1 and a stir-fry pot 2. The stir-fry pot 2 is provided with a heating component on the outside, and the heating component includes a heating coil installed on the bottom part of the stir-fry pot 2. A temperature sensor is provided inside the heating coil near the pot body. The temperature sensor and the heating coil are electrically connected to a thermostat through a wire. A high-frequency alternating current is passed through the coil to generate an alternating magnetic field, which causes eddy current heating at the bottom of the metal pot. By adjusting the frequency, duty cycle or on-off time of the coil current, the magnetic field strength is controlled, and then the heating power is adjusted. The staff can adjust the heating temperature through the thermostat according to the stir-frying temperature of the tea leaves.

[0037] A discharge port is provided at the bottom of the stir-fry pot 2, a sealing platform 3 is plugged into the inside of the discharge port, a rotating shaft 4 is rotatably connected to the inside of the sealing platform 3, one end of the rotating shaft 4 is fixedly connected to a driving component that can control the rotation of the rotating shaft 4, a stir-fry component is sleeved on the outer surface of the rotating shaft 4, the driving component is installed inside the mounting frame 5, a moving component that can control the mounting frame 5 to move up and down is fixedly installed on the mounting frame 5, a spreading component for spreading tea leaves is provided below the stir-fry pot 2, a fan frame 24 is installed on the support frame 1, and a cooling fan 25 is fixedly installed on the fan frame 24. When frying tea leaves, the staff can pour the tea leaves into the stir-fry pot 2, and then start the servo motor 6 to control the rotation shaft 4 to rotate, so that the stir-fry rack 8 can rotate inside the stir-fry pot 2 to stir the tea leaves inside the stir-fry pot 2. When the stir-frying is completed, the staff can start the servo cooling fan 25 and the electric push rod 13, and the electric push rod 13 drives the mounting rack 5 to move downward, so that the rotation shaft 4 can drive the sealing platform 3 to move downward, and the sealing platform 3 is moved out from the inside of the discharge port, so that the tea leaves inside the stir-fry pot 2 can be discharged from the discharge port, and the tea leaves can be taken out more conveniently.

[0038] During the downward movement of the mounting frame 5, the rack 19 can be driven to move downward, and the gear can be controlled to reverse, so that the rotating roller 15 rotates in the opposite direction, and the conveyor belt 16 also rotates in the opposite direction. Since the conveyor belt 16 continues to operate, the tea leaves falling from the inside of the stir-fry pot 2 can fall on different positions of the conveyor belt 16, and due to the setting of the spreading plate 21, the tea leaves on the conveyor belt 16 can be spread so that the tea leaves can be spread more evenly on the conveyor belt 16, and the cooling fan 25 continuously blows air to the conveyor belt 16 to cool the spread tea leaves. The method of cooling the stir-fried tea leaves before storing them can make the small amount of moisture contained in the tea leaves also dry, and less moisture remains, avoiding the formation of a local humid environment inside the tea packaging bag after packaging, and effectively reducing the growth of mold.

[0039] like Figure 2 As shown, the driving assembly includes a servo motor 6, which is fixedly connected to the top of the rotating shaft 4 and is fixedly installed inside the mounting frame 5. The servo motor 6 can provide rotational power to the rotating shaft 4, so that the rotating shaft 4 rotates, thereby controlling the stir-fry rack 8 to rotate, stir-frying the tea leaves inside the stir-fry pan 2, so that the tea leaves are heated more evenly.

[0040] like Figure 4 and Figure 5 The stir-fry assembly includes a fixed tube 7 sleeved on the outer surface of the rotating shaft 4, the outer surface of the fixed tube 7 is fixedly connected to the stir-fry rack 8, the outer surface of the rotating shaft 4 is fixedly connected to the baffle 9, the fixed tube 7 and the baffle 9 are connected by a supporting spring 10, the outer surface of the rotating shaft 4 is fixedly connected to a limiting protrusion 11, and a limiting groove 12 is provided inside the fixed tube 7, and the limiting protrusion 11 is inserted into the limiting groove 12. Due to the arrangement of the limiting protrusion 11 and the limiting groove 12, the fixed tube 7 and the rotating shaft 4 can move in the upper and lower directions and cannot rotate relative to each other, which can ensure that when the rotating shaft 4 rotates, the fixed tube 7 can be controlled to rotate. When discharging, the stir-fry rack 8 is blocked by the bottom of the stir-fry pot 2, so that the stir-fry rack 8 remains inside the stir-fry pot 2, and as the rotating shaft 4 continues to move downward, the supporting spring 10 can be compressed to ensure that the rotating shaft 4 moves downward without being blocked.

[0041] like Figure 3 As shown, the moving assembly includes an electric push rod 13, one end of the electric push rod 13 is fixedly connected to the mounting frame 5, and the other end of the electric push rod 13 is fixedly connected to the fixing frame 14. Both ends of the fixing frame 14 are fixedly connected to the support frame 1. The electric push rod 13 can drive the mounting frame 5 to move downward to facilitate the discharge of tea leaves.

[0042] like Figure 2 and Figure 6As shown, the spreading assembly includes two rotating rollers 15, which are connected by a conveyor belt 16. The conveyor belt 16 is arranged below the discharge port. The two rotating rollers 15 are installed inside the bracket 17 through bearings. One end of one of the rotating rollers 15 is fixedly connected to a gear 18, and the outer surface of the gear 18 is meshed with a rack 19. The rack 19 is fixedly connected to the mounting frame 5 through a reinforcing rod 20. When the rack 19 moves downward, it can drive the gear 18 to rotate in the opposite direction, and the conveyor belt 16 will run in the opposite direction, which is beneficial to the spreading of the tea leaves. When the rack 19 moves upward, it can drive the gear 18 to rotate in the forward direction, and drive the conveyor belt 16 to run in the forward direction, which is beneficial to the collection of the tea leaves.

[0043] like Figure 4 As shown, the lower surface of the sealing platform 3 is fixedly connected with a spreading plate 21, which is provided with a plurality of through holes. The spreading plate 21 can flatten the tea leaves piled on the conveyor belt 16 to ensure that the tea leaves are spread more evenly and the tea leaves have a better cooling effect.

[0044] like Figure 3 As shown, the support frame 1 and the bracket 17 are both fixedly mounted on the upper surface of the base frame 22. The base frame 22 is fixedly connected to the ground by fixing bolts, so that the equipment is more stable. During the stir-frying of tea leaves, it is not easy to shake and has better stability. A tea collection box 23 is placed on the base frame 22. The tea collection box 23 is placed below one end of the conveyor belt 16. The tea collection box 23 is an open and uncovered design. Tea leaves falling from the conveyor belt 16 can fall directly into the tea collection box 23. The tea collection box 23 can collect the cooled tea leaves. A handle is fixedly connected to one side of the tea collection box 23. The staff pulls the handle to facilitate the movement of the tea collection box 23.

[0045] The servo motor 6, electric push rod 13, and cooling fan 25 are all electrically connected to the control switch through wires. The control switch can control the start and stop of the servo motor 6, electric push rod 13, and cooling fan 25 through corresponding buttons, and the above-mentioned pad components are all powered by 220V voltage.

[0046] When frying tea leaves, the staff can pour the tea leaves into the stir-fry pot 2, and then start the servo motor 6 to control the rotating shaft 4 to rotate, so that the stir-fry rack 8 can rotate inside the stir-fry pot 2 to stir the tea leaves inside the stir-fry pot 2. When the stir-frying is completed, the staff can start the servo cooling fan 25 and the electric push rod 13, and the electric push rod 13 drives the mounting frame 5 to move downward, so that the rotating shaft 4 can drive the sealing platform 3 to move downward, and the sealing platform 3 is moved out from the inside of the discharge port, so that the tea leaves inside the stir-fry pot 2 can be discharged from the discharge port, and the tea leaves are taken out more conveniently. In the process of the mounting frame 5 moving downward, the rack 19 can be driven to move downward, and the gear can be controlled to reverse, so that the rotating roller 15 rotates in the opposite direction, and the conveyor belt 16 also rotates in the opposite direction. Since the conveyor belt 16 continues to operate, the tea leaves falling from the inside of the stir-fry pot 2 can fall on the surface of the stir-fry pot 2. At different positions of the conveyor belt 16, and due to the setting of the spreading plate 21, the tea leaves on the conveyor belt 16 can be spread so that the tea leaves can be spread more evenly on the conveyor belt 16, and the cooling fan 25 continues to blow air to the conveyor belt 16 to cool the spread tea leaves. When the tea leaves need to be fried again, the staff can start the electric push rod 13, and the electric push rod 13 can drive the mounting frame 5 to move upward, so that the rotating shaft 4 drives the sealing platform 3 to move upward, and the sealing platform 3 can seal the discharge port. At this time, since the rack 19 moves upward, the gear 18 can be rotated forward, so that the conveyor belt 16 rotates forward. During the forward rotation of the conveyor belt 16, the tea leaves can be driven to move to the right. During the movement, the tea leaves can fall into the tea collection box 23 below the conveyor belt 16 in sequence, making tea collection more convenient.

[0047] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments and that various modifications and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
