Description

Technical Field

[0001] The present invention relates to the technical field related to black tea fermentation, and particularly to an apparatus and method for promoting black tea fermentation by precise pulsed light. Background Art

[0002] The main purpose of black tea fermentation is to improve the taste, enrich the flavor and aroma of tea leaves, and at the same time to form the unique color, aroma and taste quality of black tea. At present, the method for black tea fermentation is mainly carried out by promoting with pulsed light. The related apparatus for promoting black tea fermentation by precise pulsed light is a technical device that uses light pulses of specific wavelengths and frequencies to optimize the black tea fermentation process. Traditional black tea fermentation depends on the temperature and humidity in the natural environment.

[0003] When promoting black tea fermentation by precise pulsed light, the black tea is first placed in a specific tray, and the light source of the pulsed light is mainly provided by devices such as LEDs or laser diodes. The pulsed light device is placed at a certain position above the tray. Then, when the pulsed light device is started, it regulates specific wavelengths and frequencies according to the background operating system to assist in the fermentation of the black tea material in the tray and improve the fermentation efficiency of black tea. However, when the black tea is placed on the tray, due to the different shapes of the black tea leaves, there is an overlapping phenomenon when placed, and the tea leaves blocked are not conducive to receiving the irradiation of the pulsed light. At the same time, the oxygen, humidity and temperature in the fermentation environment can all affect the oxidation-reduction reactions of polyphenol oxidase and other related enzymes. Due to the humidity, there will be a certain viscosity between the black tea, causing the material to adhere and accumulate. The overlapping tea leaves will affect the adjustment of relevant parameters during fermentation, thereby affecting the fermentation process. Summary of the Invention

[0013] A method for using a device for promoting black tea fermentation using precise pulsed light, the method comprising the following steps: Step 1: When in use, place the black tea material in the material placement area on the tray, then start the second motor and drive the threaded rod to rotate, and adjust the height of the sleeve according to the thickness of the tea material accumulation, thereby adjusting the spacing between the mixing piece and the bottom of the material placement area; Step 2: Start the driving member 1, drive and drive the mixing rod to perform circular motion with the axis of the tray as the center, and the plurality of toggle bars on the support rod will push the black tea material forward, thereby flattening the black tea material accumulated in the material placement area and spreading it flat on the material placement area; Step 3: The second driving member drives the driven rod to move in the vertical direction, thereby driving the light source member connected to the driven rod to move. The distance between the light source member and the tray can be adjusted according to the pre-calculated humidity and material volume of the black tea material, so that the black tea material is initially exposed to a certain intensity of irradiation, which is convenient for improving the efficiency of black tea fermentation. Step 4: The temperature sensor and humidity sensor on the control component sense the temperature and humidity near the black tea on the tray, and then output corresponding signals. The controller receives the signals of the temperature and humidity, and then outputs corresponding control instructions. The controller controls the driving part two to adjust the distance between the light source part and the tray. When the light source part moves away from the tray, correspondingly, the intensity of the pulsed light irradiation required for the fermentation of the black tea material becomes lower, and the generated heat will also decrease correspondingly. The movement of the driven rod drives the electrode plate to move on the resistance wire, and one of the wiring terminals is electrically connected to the fan part with a heating wire. According to the change of the resistance, the output power of the fan part is controlled, and finally the output wind speed is adjusted. Step 5: When the black tea is fermenting, start the ventilation component to extract the air in the gaps of the black tea piled up at the bottom of the material placement area, and then extract the water vapor generated by the black tea. At the same time, under the action of the fan part, the water vapor rising above the black tea is blown, and one of the fan parts extracts the water vapor to the outside of the tank body. During this period, the operation of the pump body is regulated by the controller, and the controller outputs control instructions according to the temperature sensor and humidity sensor.

[0014] The beneficial effects of the present invention are as follows: 1. In the present invention, by arranging a mixing part in the material placement area of the tray, and the mixing part can rotate itself when moving, so while turning over the black tea material, it can also spread the piled-up black tea material evenly in the material placement area. Under the action of the ventilation component and the wind force component, the humidity between the black tea materials is effectively controlled, the viscosity caused by humidity between the black teas is reduced, and the materials will not adhere and pile up. With the use of the mixing part, the black tea materials can be evenly irradiated by the pulsed light, thus ensuring the fermentation efficiency of the black tea materials.

[0015] 2. In the present invention, corresponding light source parts are arranged on the upper and lower sides of the tray with transparent characteristics to irradiate the black tea in the material placement area of the tray with pulsed light, and the two light source parts can move relatively or in opposite directions under the cooperation between the driven rod and the driving part two to adjust the irradiation effect and intensity on the black tea, ensuring the fermentation effect of the black tea.

[0016] 3. In the present invention, an electrode plate is arranged on one of the driven rods. When the driven rod moves, it drives the electrode plate to move on the resistance wire, and one of the wiring terminals is electrically connected to the fan part with a heating wire. According to the change of the resistance, the output power of the fan part is controlled, and finally the output wind speed is adjusted, increasing the automation of the fan part output and simplifying the complexity when the controller outputs control instructions.

[0017] 4. In the present invention, through two wind power components, while hot air can be input into the tank, the moisture generated by the black tea fermentation and located above the material placement area can also be carried away. One of the wind power components blows air over the upper part of the material placement area, forming suction forces on both sides of the air flow, and then entraining the moisture to be discharged from the position of the other wind power component. During this period, it is avoided that the air directly acts on the surface of the black tea and blows the position of the black tea, thereby affecting the irradiation of the black tea by the pulsed light.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. Example

[0022] Device and method for promoting black tea fermentation by precise pulsed light, such as Figure 1 - Figure 9 As shown, it includes a tank body 1 with sliding slots 2 at both ends, a transparent tray 3 arranged at the center of the tank body 1, a mixing component 5 arranged on the material placement area 4, a ventilation component, a light source component 6 arranged on the top and bottom of the tray 3, and a control component; specifically: The tray 3 is a cylindrical structure with an opening at one end. The inside of the tray 3 is a material placement area 4 for placing tea leaves. The material placement area 4 has a certain depth, which is set according to the volume of the fermented black tea belt and the thickness of the belt. The tank body 1 is provided with a feed port 40. The output end of the feed port 40 corresponds to the material placement area 4 of the tray 3. Black tea materials can be added to the material placement area 4 through the feed port 40. The mixing member 5 is driven by a driving member arranged on the tray 3 and performs a circular motion with the axis of the tray 3 as the center. The mixing member 5 is mainly used to enter the material from the feed port 40 to the material placement area 4. The piled black tea material is flattened to make it spread in the material placement area 4, which is convenient for the subsequent pulse light irradiation operation; the ventilation component is used to extract the air between the gaps of the tea leaves attached to the bottom of the material placement area 4. Because the black tea will be piled up together when placed, the black tea material will have a certain thickness. When the black tea is fermented, heat and water vapor will be generated, and the black tea material near the bottom of the material placement area 4 is not easy to emit water vapor, which will affect the fermentation efficiency. Therefore, a ventilation component is provided to extract the air between the gaps of the tea leaves; The output ends of the light source components 6 are all facing the tray 3, so that a displacement mechanism for driving the light source components 6 to move relative to each other is provided on the tank body 1. Since the tray 3 is made of a transparent material, the pulse light output by the light source components 6 can act on the black tea material near the bottom of the material placement area 4. Therefore, when the irradiation intensity of the black tea material is adjusted and the light source components 6 need to be moved, in order to ensure that the irradiation intensity of the top and bottom of the black tea in the material placement area 4 is consistent, the displacement mechanism can be used to make the two light source components 6 move synchronously, thereby ensuring the consistency of the taste of the fermented black tea at the top and bottom of the material; The control component is used to adjust the temperature and humidity at the position of the material placement area 4, and the controller 31 is also used to control the operation and regulation of the driving member 1, the ventilation component and the displacement mechanism, thereby increasing the degree of automation of the device structure; The control component includes a controller 31 arranged on the tank body 1 and a temperature sensor 32 and a humidity sensor 33 arranged inside the tank body 1 and used to detect the temperature and humidity of the material placement area 4. The temperature sensor 32 and the humidity sensor 33 can perform real-time detection of the black tea in the material placement area 4 to ensure that the fermentation is carried out normally and efficiently.

[0023] In order to solve the problem of moving and adjusting the height of the mixing member 5; Figure 6 - Figure 8As shown in the figure, the first driving member includes a rotating shaft 7 rotatably connected to the tray 3 and a first motor 8. The rotating shaft 7 is connected to the output end of the first motor 8. A sleeve 9 is slidably connected to the rotating shaft 7. Ear plates 10 are provided on both sides of the sleeve 9. A threaded rod 11 is threadedly connected to one of the ear plates 10, and a limiting rod 12 is slidably connected to the other ear plate 10. One ends of the threaded rod 11 and the ear plate 10 are respectively connected to the rotating shaft 7. A second motor 13 is installed on the sleeve 9, and the output end of the second motor 13 is connected to the other end of the threaded rod 11. By starting the second motor 13 to drive the threaded rod 11 to rotate, according to the thickness of the tea material accumulation, the height of the sleeve 9 is adjusted, and thus the distance between the mixing member 5 and the bottom of the material placement area 4 is adjusted.

[0024] To solve the problem that the black tea material in the material placement area 4 can be evenly irradiated by pulsed light; as Figure 8 shown in the figure, the mixing member 5 is composed of a support rod 14 and a plurality of stirring bars 15 connected to the support rod 14. There are flow gaps between the stirring bars 15; A third motor 16 is installed on the sleeve 9. One end of the support rod 14 passes through the sleeve 9 and is connected to the output end of the third motor 16. The third motor 16 drives the support rod 14 to rotate, thereby driving a plurality of stirring bars 15 to perform circular motion around the central axis of the support rod 14. When used in cooperation with the first driving member, it can be realized that while the mixing plate moves itself, the black tea material in the material placement area 4 is turned over, thus ensuring the uniformity of the pulsed light irradiation of the black tea material.

[0025] To solve the problem that the water vapor generated in the gaps of the black tea material in the tray 3 cannot be effectively discharged; as Figure 6 - Figure 8 shown in the figure, therefore, the device structure further includes a plurality of first holes 17 opened on the side wall of the material placement area 4 of the tray 3 and a plurality of second holes 18 opened on the bottom wall of the material placement area 4. The plurality of first holes 17 are equidistantly arranged around the central axis of the tray 3 and are close to the bottom position of the material placement area 4. The plurality of second holes 18 are dispersedly arranged in a fan-shaped area 19 on the tray 3; An annular seal 20 is sleeved on the outer side wall of the tray 3, and the annular seal 20 corresponds to the positions of a number of first holes 17. A first air duct 201 is provided at the output end of the annular seal 20. A sector seal 21 is provided at the bottom of the tray 3 and at a position corresponding to the sector area 19. A second air duct 211 is provided at the output end of the sector seal 21. A pump body 22 is provided on the tank body 1. The output ends of the first air duct 201 and the second air duct 211 are both connected to the input end of the pump body 22. When the pump body 22 is operating, the air flowing in the annular seal 20 and the sector seal 21 is pumped out through the first air duct 201 and the second air duct 211, so as to form a negative pressure environment at the positions of the first holes 17 and the second holes 18. The water vapor between the gaps of the black tea will flow into the annular seal 20 and the sector seal 21 under the traction of the negative pressure, and finally will be pumped out by the pump body 22 and discharged to the outside of the tank body 1.

[0026] To solve the problem of the two light source components 6 moving towards or away from each other synchronously; as Figure 1 - Figure 3 shown, the displacement mechanism includes two U-shaped driven rods 23 respectively slidably connected to the two sliding slots 2 and a second driving member for driving the two driven rods 23 to linearly move towards or away from each other. One end of the driven rod 23 extends into the tank body 1 and is connected to the light source component 6, and the other end of the driven rod 23 extends to the outside of the tank body 1 and is connected with a rack 24, and the positions of the two racks 24 are opposite; the second driving member includes a rotating gear 25 and a driving motor 26 for driving the rotating rack 24 to be rotationally connected. Both of the two racks 24 are engaged with the rotating gear 25. When the driving motor 26 is started, the driving motor 26 will drive the rotating gear 25 to rotate, thereby driving the two racks 24 to move towards or away from each other, and further driving the driven rod 23 to slide on the tank body 1, and finally driving the light source component 6 to move.

[0027] When this embodiment is in use, the black tea material is placed in the material placement area 4 on the tray 3, and then the second motor 13 is started to drive the threaded rod 11 to rotate. According to the thickness of the accumulated tea material, the height of the sleeve 9 is adjusted, and then the distance between the mixing part 5 and the bottom of the material placement area 4 is adjusted. The first driving part is started, and then the black tea material accumulated in the material placement area 4 can be leveled and spread flat on the material placement area 4. Then, the second driving part drives the driven rod 23 to move in the vertical direction, and then drives the light source part 6 connected to the driven rod 23 to move. The distance between the light source part 6 and the tray 3 can be adjusted according to the pre-measured humidity and the volume of the black tea material, so that the black tea material will be exposed to a certain intensity of irradiation initially, which is convenient for improving the efficiency of black tea fermentation. The controller 31 will control the second driving part to adjust the distance between the light source part 6 and the tray 3. When the black tea is fermenting, the ventilation assembly is started to extract the air between the gaps of the black tea accumulated at the bottom of the material placement area 4, and then the water vapor generated by the black tea will be extracted. Through the mutual cooperation of the above structures, it is possible to ensure that the environment during the fermentation of black tea is within a suitable range. Embodiment

[0028] Device and method for promoting black tea fermentation by precise pulsed light, as Figure 4 and Figure 9 shown, to solve the problem of air flow above the tray 3; on the basis of Embodiment 1, the following improvements are made in this embodiment: Two wind force components are provided on the tank body 1. The wind force components are used to promote the air flow near the tray 3, and the positions of the two wind force components are opposite. The wind force component includes an air box 27 and a fan part 28 arranged inside the air box 27. One of the two wind force components is used to extract the air in the tank body 1, and the other is used to input air into the tank body 1; A one-way air nozzle 29 is provided on one of the air boxes 27, and a heating wire 30 is provided on the other air box 27. The fan part 28 in the air box 27 where the one-way air nozzle 29 is located is used to extract the air in the tank body 1, and the fan part 28 in the air box 27 where the heating wire 30 is located is used to inject air into the tank body 1. The heating wire 30 is regulated by the controller 31. When the temperature of the peripheral environment of the black tea material decreases, the heating wire 30 is started, so that the air flow input into the tank body 1 by the fan part 28 has a temperature, thereby improving the temperature inside the tank body 1 and making the temperature inside the tank body 1 more suitable for the fermentation operation of black tea; A connecting member 34 is provided on one of the follower rods 23. One end of the connecting member 34 is connected with an electrode plate 35. A pole 36 is provided at the position where the electrode plate 35 is located. A resistance wire 37 is provided on the pole 36. The electrode plate 35 is in contact with the resistance wire 37. Connecting terminals 38 are respectively provided at both ends of the pole 36. A conducting wire 39 is connected between one of the connecting terminals 38 and the electrode plate 35. And this connecting terminal 38 is electrically connected with the fan member 28 in the air box 27 provided with the heating wire 30.

[0029] When this embodiment is in use, according to the temperature sensor 32 and the humidity sensor 33 on the control assembly, the temperature and humidity near the black tea on the tray 3 will be sensed, and then corresponding signals will be output. The controller 31 will receive the signals of the temperature and humidity, and then output corresponding control instructions. The controller 31 will control the second driving member to adjust the distance between the light source member 6 and the tray 3. When the light source member 6 is far away from the tray 3, correspondingly, at this time, the irradiation intensity of the pulsed light required for the fermentation of the black tea material becomes lower, and the generated heat will also be reduced correspondingly. The movement of the follower rod 23 will drive the electrode plate 35 to move on the resistance wire 37. And one of the connecting terminals 38 is electrically connected with the fan member 28 provided with the heating wire 30. According to the change of the resistance, the output power of the fan member 28 is controlled, and finally the output wind speed is adjusted.

10. A method for using the device for promoting black tea fermentation by precise pulsed light according to claims 1-9, characterized in that: The method of use includes the following steps: Step 1: When in use, place the black tea material in the material placement area (4) on the tray (3), then start the second motor (13) and drive the threaded rod (11) to rotate, and adjust the height of the sleeve (9) according to the thickness of the tea material accumulation, thereby adjusting the spacing between the mixing element (5) and the bottom of the material placement area (4); Step 2: Start the driving member 1 to drive and drive the mixing rod to perform a circular motion with the axis of the tray (3) as the center, and the plurality of toggle bars (15) on the support rod (14) will push the black tea material forward, thereby flattening the black tea material accumulated in the material placement area (4) and spreading it evenly on the material placement area (4); Step 3: The second driving member drives the driven rod (23) to move in the vertical direction, thereby driving the light source member (6) connected to the driven rod (23) to move. The distance between the light source member (6) and the tray (3) can be adjusted according to the pre-calculated humidity and material volume of the black tea material, so that the black tea material is initially exposed to a certain intensity of radiation, thereby improving the efficiency of black tea fermentation. Step 4: The temperature sensor (32) and the humidity sensor (33) on the control component sense the temperature and humidity near the black tea on the tray (3), and then output corresponding signals. The controller (31) receives the temperature and humidity signals and then outputs corresponding control instructions. The controller (31) controls the driving component 2 to adjust the spacing between the light source component (6) and the tray (3). When the light source component (6) is away from the tray (3), the intensity of the pulse light required for the fermentation of the black tea material becomes lower, and the heat generated is also reduced accordingly. The movement of the driven rod (23) drives the electrode sheet (35) to move on the resistance wire (37), and one of the wiring terminals (38) is electrically connected to the fan component (28) with the heating wire (30).

At the same time, under the action of the fan component (28), the water vapor rising above the black tea is blown away, and one of the fan components (28) extracts the water vapor to the outside of the tank body (1). During this period, the operation of the pump body (22) is regulated by the controller (31), and the controller (31) outputs control instructions according to the temperature sensor (32) and the humidity sensor (33).
