Description

Technical Field

[0001] This invention relates to the field of tea-making equipment technology, and in particular to an automatic detection system for the blooming of black tea and an intelligent drying room. Background Technology

[0002] The "golden flowers" on tea are formed during the drying process of dark tea. These golden flowers, also known as *Eurotium cristatum*, are a type of probiotic that naturally grows on dark tea under specific temperature and humidity conditions. Extensive research and clinical data show that *Eurotium cristatum* can effectively enhance the human immune system and has anti-cancer, antioxidant, and anti-aging effects. The drying process directly affects the normal growth of *Eurotium cristatum* in dark tea. The national standard for dark tea products includes *Eurotium cristatum* as an indicator, and the quantity of *Eurotium cristatum* directly affects the quality grade and selling price of dark tea products.

[0003] Existing technologies still have some shortcomings in the fermentation process of dark tea in a drying room:

[0004] 1. In the existing technology, hot air or atomized water vapor is directly injected or discharged into the drying room to control the temperature and humidity of the drying room when black tea is fermenting. However, when cooling is required, the hot air is directly discharged, which easily causes heat loss and thus causes a lot of energy consumption during the fermentation process.

[0005] 2. In the existing technology, black tea is directly placed into the material rack for fermentation. However, when black tea is placed in the material rack, the black tea at the bottom cannot be heated evenly, which affects the fermentation of the whole black tea.

[0006] To address the aforementioned issues, this invention proposes an automatic detection system for black tea mold growth and an intelligent drying room. Summary of the Invention

[0007] The purpose of this invention is to solve the problem in the prior art that the fermentation process of black tea causes a lot of energy consumption and the bottom layer of black tea cannot be heated evenly, affecting the fermentation of the whole black tea. The invention proposes an automatic detection system for black tea fermentation and an intelligent drying room.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A smart drying chamber for black tea to develop its characteristic bloom includes a drying chamber shell. A hollow fixing column is longitudinally fixed inside the drying chamber shell. An annular air injection pipe is fixed to the bottom inner wall of the drying chamber shell by bolts. An external connecting pipe is fixedly inserted through one side of the drying chamber shell. One end of the external connecting pipe is connected to an external heat source, and the other end of the external connecting pipe is connected to the annular air injection pipe. The annular air injection pipe has multiple air injection holes for discharging hot air. The annular air injection pipe is connected to the hollow fixing column by a guide pipe.

[0010] A circulation structure is installed on one side of the drying chamber shell to circulate the hot air inside the drying chamber shell and reduce the waste of heat energy.

[0011] The uniform blooming structure is set on the outer wall of the hollow fixed column to ensure that the black tea is heated evenly and develops blooms.

[0012] In one possible design, the circulation structure includes a heat exchange box disposed on the side of the drying chamber shell away from the external connecting pipe. A gas collecting hood is welded to the top of the drying chamber shell. The top of the drying chamber shell has multiple through holes communicating with the gas collecting hood. An exhaust fan is provided on the inner wall of the top of the gas collecting hood. Multiple connecting pipes are fixedly inserted through the top of the gas collecting hood. The top ends of the multiple connecting pipes are fixedly connected to the same annular pipe. A first insulating pipe is provided on one side of the annular pipe. A gas transfer ball is fixed to the bottom end of the first insulating pipe. A second insulating pipe is provided on one side of the gas transfer ball, and the second... The bottom end of the insulation pipe extends into the drying chamber shell and is connected to the annular air injection pipe. The outer wall of the hollow fixed column is provided with multiple exhaust holes. The external connecting pipe is connected to the heat source of the outer wall, and injects the external hot air into the annular air injection pipe and the hollow fixed column respectively. The air injection holes and exhaust holes discharge the hot air from the outside to the inside and from the inside to the outside respectively, which promotes the fermentation of black tea placed in the frame of the arc-shaped hollow feeding plate. The operation of the exhaust fan can discharge the upward floating hot air from the drying chamber shell into the first insulation pipe, the second insulation pipe and then into the annular air injection pipe in sequence, so as to recycle the hot air and avoid the waste of heat energy caused by direct discharge.

[0013] In one possible design, the circulation structure further includes an annular water pipe disposed on the inner wall of the drying chamber shell. Multiple electromagnetic atomizing nozzles are located on the side of the annular water pipe near the hollow fixed column. A heat exchange tube is disposed inside the heat conversion chamber. The top end of the heat exchange tube penetrates the top of the heat conversion chamber and is connected to a gas transfer sphere. The bottom end of the heat exchange tube extends into the drying chamber shell and is connected to an annular gas injection pipe. An exhaust pipe is located on one side of the gas transfer sphere. A water pump is bolted to the top of the heat conversion chamber. An inlet pipe is fixed to the inlet of the water pump, and the bottom end of the inlet pipe extends into the heat conversion chamber. An outlet pipe is fixed to the outlet of the water pump, and one end of the outlet pipe extends into the drying chamber shell and is connected to the annular water pipe. During cooling, the solenoid valves on the second insulation pipe and the exhaust pipe are closed, and the solenoid valve on the heat exchange tube is opened. Hot gas enters the heat conversion chamber through the transfer of the gas transfer sphere. Inside the chamber, the hot air completes the heat conversion within the heat exchange chamber, heating the water inside. The cooled gas then enters the annular air injection pipe, further cooling the interior of the drying chamber and preventing heat waste caused by direct discharge. When the humidity is too high, the solenoid valves on the second insulation pipe and heat exchange pipe are closed, while the solenoid valve on the exhaust pipe is opened. At this point, the hot air carrying water vapor is discharged to the outside (the exhaust pipe can discharge hot air and water vapor into the heat exchange chamber to heat the water inside, or it can be used as a heat source elsewhere to reduce heat consumption). When the temperature and humidity sensor detects insufficient humidity inside the drying chamber, the water pump is activated. The water pump pumps the water heated by the hot air into the annular water pipe, which sprays hot water into the drying chamber through an electromagnetic atomizing nozzle to increase humidity. The sprayed water is hot water, thus preventing a significant drop in temperature caused by increased humidity.

[0014] In one possible design, the uniform blooming structure includes a cross-shaped bottom plate rotatably fitted onto the outer wall of a hollow fixed column, a cross-shaped top plate rotatably connected to the inner top wall of the drying chamber shell, and the top of the hollow fixed column penetrating the cross-shaped top plate. The cross-shaped bottom plate and the cross-shaped top plate are coaxial, and multiple sliding rods are fixedly connected between the cross-shaped bottom plate and the cross-shaped top plate. Multiple rotating rings are rotatably fitted onto the outer wall of the hollow fixed column from top to bottom, and the bottom ends of the multiple sliding rods are fixedly penetrating the rotating rings. Multiple support plates are arranged in a ring on the outer wall of the rotating rings, and arc-shaped hollowed-out feeding plates are slidably fitted onto the tops of the multiple support plates. When the cross-shaped bottom plate and the cross-shaped top plate rotate, they can drive the support plates and the arc-shaped hollowed-out feeding plates to rotate. At this time, the hot air ejected from the air injection hole and the air exhaust hole is discharged from the outside to the inside and from the inside to the outside, respectively. The inside and outside work together to uniformly dry and bloom the black tea placed on the arc-shaped hollowed-out feeding plate.

[0015] In one possible design, the uniformly patterned structure further includes a nut ring fitted onto the outer wall of the hollow fixed column, with the nut ring located below the top cross plate. The top outer wall of the hollow fixed column has a reciprocating thread section, and the nut ring is threadedly connected to the hollow fixed column through the reciprocating thread section. Multiple rotating rods are rotatably connected to the top of the bottom cross plate. Multiple first rectangular holes are provided inside the top cross plate, and second rectangular holes are provided inside the support plate. The top ends of the rotating rods sequentially pass through the multiple second rectangular holes and extend into the first rectangular holes. The first and second rectangular holes limit the movement of the rotating rods. A first connecting rod is rotatably connected to the side of each rotating rod away from the hollow fixed column. The other ends of the multiple first connecting rods are rotatably connected to corresponding arc-shaped hollowed-out feeding plates. Each rotating rod is rotatably connected to a second connecting rod on the side near the hollow fixed column. The top ends of multiple second connecting rods are rotatably connected to a nut ring. The cross base plate, cross top plate, nut ring, and sliding rod rotate. The nut ring is threadedly connected to the reciprocating thread section. Therefore, during rotation, the nut ring moves up and down under the action of the reciprocating thread section. The reciprocating thread section drives the rotating rod to rotate back and forth through the second connecting rod. When the rotating rod rotates outward, it pushes the arc-shaped hollow feeding plate outward through the first connecting rod. The multiple arc-shaped hollow feeding plates arranged vertically move outward a different distance under the action of the rotating rod. Therefore, the upward floating hot air can rise from the bottom of the arc-shaped hollow feeding plate to ferment the black tea in the frame, avoiding the vertical stacking of black tea and causing the black tea in the upper layer to not ferment evenly.

[0016] In one possible design, the support plate has multiple second arc-shaped blocks on both sides of its top, and the arc-shaped hollow feeding plate has multiple first arc-shaped blocks on both sides of its bottom. The first arc-shaped blocks cooperate with the second arc-shaped blocks. The bottom of the arc-shaped hollow feeding plate is welded with a limiting block, which extends into and cooperates with the second rectangular hole. When the arc-shaped hollow feeding plate moves, the cooperation of the first and second arc-shaped blocks causes the arc-shaped hollow feeding plate to bounce up and down, thereby vibrating the black tea fixed in the frame of the arc-shaped hollow feeding plate. This facilitates the fermentation of the inner layer of black tea, achieving the purpose of uniform fermentation of the black tea.

[0017] In one possible design, a bevel gear ring is bolted to the bottom of the cross-shaped base plate, a drive motor is bolted to the bottom inner wall of the drying chamber shell, a bevel gear that meshes with the bevel gear ring is fixed to the output shaft of the drive motor, and a temperature and humidity sensor is bolted to one side inner wall of the drying chamber shell.

[0018] In one possible design, the outer walls of the second insulation pipe, exhaust pipe, and heat exchange pipe are all equipped with solenoid valves, and a smart control panel is provided on one side of the drying chamber shell. The smart control panel is electrically connected to the solenoid valves, drive motor, water pump, and electromagnetic atomizing nozzle.

[0019] In one possible design, multiple connecting plates are fixed from top to bottom on one inner wall of the drying chamber shell, and the multiple connecting plates are respectively located above adjacent support plates. A camera is fixed to the bottom side of the connecting plate by bolts, and the camera is electrically connected to the intelligent control panel. When the black tea on the arc-shaped hollow feeding plate is fermenting, the arc-shaped hollow feeding plate rotates under the action of the rotating rod and the rotating ring and moves back and forth in a reciprocating manner to evenly ferment the black tea. When the arc-shaped hollow feeding plate moves outward, the camera can clearly capture the video of the black tea fermenting, which makes it convenient for the staff to check the fermentation status of the black tea in real time.

[0020] An automatic detection system for black tea mold growth includes the aforementioned intelligent drying room for black tea mold growth.

[0021] In this invention, a gas collecting hood is welded to the top of the drying chamber shell. The top of the drying chamber shell has multiple through holes connected to the gas collecting hood, which are arranged in a ring around a hollow fixed column. An exhaust fan is provided on the inner wall of the top of the gas collecting hood. The top of the gas collecting hood is fixedly connected to a ring pipe through multiple connecting pipes. A first insulation pipe is provided on one side of the ring pipe, and the bottom end of the first insulation pipe is connected to the ring air injection pipe. The operation of the exhaust fan can discharge the upward floating hot air from the drying chamber shell into the first insulation pipe, the second insulation pipe, and then into the ring air injection pipe in sequence, so as to recycle the hot air and avoid the waste of heat energy caused by direct discharge.

[0022] In this invention, the heat exchange box is equipped with a heat exchange tube. The top end of the heat exchange tube is connected to a gas transfer ball, and the bottom end of the heat exchange tube is connected to an annular gas injection pipe. An exhaust pipe is provided on one side of the gas transfer ball. A water pump is fixed to the top of the heat exchange box by bolts. Hot gas enters the heat exchange box through the gas transfer ball, heating the water inside the heat exchange box. After re-entering the drying chamber shell, it can play a cooling role, avoiding the waste of heat energy caused by direct discharge. When the humidity inside the drying chamber shell is insufficient, the water pump pumps the water heated by the hot gas into the annular water pipe. The hot water is sprayed into the drying chamber shell through an electromagnetic atomizing nozzle to increase the humidity. The sprayed water is hot water, thus avoiding a large drop in temperature caused by increasing humidity.

[0023] In this invention, the nut ring is threadedly connected to the hollow fixed column via a reciprocating threaded section. Multiple rotating rods are rotatably connected to the top of the cross-shaped base plate. These rotating rods are rotatably connected to the arc-shaped hollowed-out feeding plate via a first connecting rod, and to the nut ring via a second connecting rod. The nut ring is threadedly connected to the reciprocating threaded section, thus, during rotation, the nut ring moves up and down reciprocally under the action of the reciprocating threaded section. The reciprocating threaded section pushes the arc-shaped hollowed-out feeding plate outwards via the second connecting rod and the rotating rods. The multiple arc-shaped hollowed-out feeding plates arranged vertically move outwards at different distances under the action of the rotating rods. Therefore, the upward-floating hot air can rise from the bottom of the arc-shaped hollowed-out feeding plate and promote the fermentation of the black tea in the frame, preventing the black tea from being vertically piled up and causing uneven fermentation of the higher layers of black tea.

[0024] In this invention, the support plate has multiple second arc-shaped blocks on both sides of its top, and the arc-shaped hollow feeding plate has multiple first arc-shaped blocks on both sides of its bottom. The first arc-shaped blocks cooperate with the second arc-shaped blocks. The bottom of the arc-shaped hollow feeding plate is welded with a limiting block, which extends into the second rectangular hole and cooperates with the second rectangular hole. When the arc-shaped hollow feeding plate moves, the cooperation of the first and second arc-shaped blocks causes the arc-shaped hollow feeding plate to bounce up and down, thereby vibrating the black tea fixed in the frame of the arc-shaped hollow feeding plate, which facilitates the fermentation of the inner layer of black tea, so as to achieve the purpose of uniform fermentation of black tea.

[0025] In this invention, the hot air inside the drying chamber can be circulated more effectively to promote the fermentation of black tea. The hot air can also heat the water in the heat conversion box for later humidification, avoiding the waste of heat energy. In addition, when the cross-shaped base plate rotates, it can drive multiple arc-shaped hollow feeding plates arranged vertically to move on the corresponding horizontal plane. This not only ensures that the arc-shaped hollow feeding plates at different heights are heated evenly to promote fermentation, but also vibrates the black tea placed on the arc-shaped hollow feeding plates as they move, facilitating the fermentation of the inner layer of black tea and achieving the goal of uniform fermentation of black tea.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1

[0039] Reference Figures 1-9 The intelligent drying chamber for black tea fermentation is used in the field of tea-making equipment. It includes a drying chamber shell 1, a hollow fixed column 7 fixed longitudinally inside the drying chamber shell 1, an annular air injection pipe 3 fixed to the bottom inner wall of the drying chamber shell 1 by bolts, an external connecting pipe 5 fixed through one side of the drying chamber shell 1, one end of the external connecting pipe 5 is connected to an external heat source, and the other end of the external connecting pipe 5 is connected to the annular air injection pipe 3. The annular air injection pipe 3 is provided with multiple air injection holes 4 for discharging hot air, and the annular air injection pipe 3 and the hollow fixed column 7 are connected by a guide pipe 6.

[0040] Reference Figures 2-5 The intelligent drying oven also includes a circulation structure located on one side of the drying oven shell 1 for recycling the hot air inside the drying oven shell 1, reducing heat energy waste. The circulation structure includes a heat conversion box 19 located on the side of the drying oven shell 1 away from the external connecting pipe 5. A gas collecting hood 11 is welded to the top of the drying oven shell 1. The top of the drying oven shell 1 has multiple through holes 10 connected to the gas collecting hood 11. An exhaust fan 12 is provided on the inner wall of the top of the gas collecting hood 11. Multiple connecting pipes 13 are fixedly passed through the top of the gas collecting hood 11. The top ends of the multiple connecting pipes 13 are fixedly connected to the same annular pipe 14. A first heat-insulating pipe 15 is provided on one side of the annular pipe 14. A gas transfer ball 16 is fixed at the bottom end of the first heat-insulating pipe 15. A second heat-insulating pipe 17 is provided on one side of the rotating ball 16, and the bottom end of the second heat-insulating pipe 17 extends into the drying chamber shell 1 and is connected to the annular air injection pipe 3. The outer wall of the hollow fixed column 7 is provided with multiple exhaust holes 8. The external connecting pipe 5 is connected to the heat source of the outer wall, and injects the external hot air into the annular air injection pipe 3 and the hollow fixed column 7 respectively. The air injection hole 4 and the exhaust hole 8 respectively discharge the hot air from the outside to the inside and from the inside to the outside, so as to make the black tea placed in the frame of the arc-shaped hollow feeding plate 32 bloom. The operation of the exhaust fan 12 can discharge the upward floating hot air from the drying chamber shell 1 into the first heat-insulating pipe 15 and the second heat-insulating pipe 17 in sequence, and then into the annular air injection pipe 3, so as to circulate the hot air and avoid the waste of heat energy caused by direct discharge.

[0041] Reference Figures 3-5The circulation structure also includes an annular water pipe 24 installed on the inner wall of the drying chamber shell 1. Multiple electromagnetic atomizing nozzles 25 are provided on the side of the annular water pipe 24 near the hollow fixed column 7. A heat exchange pipe 20 is installed inside the heat conversion box 19. The top end of the heat exchange pipe 20 penetrates the top of the heat conversion box 19 and is connected to the gas transfer ball 16. The bottom end of the heat exchange pipe 20 extends into the drying chamber shell 1 and is connected to the annular air injection pipe 3. An exhaust pipe 18 is provided on one side of the gas transfer ball 16. The top of the heat conversion box 19... A water pump 21 is fixed to the unit by bolts. An inlet pipe 22 is fixed to the inlet of the water pump 21, and the bottom end of the inlet pipe 22 extends into the heat exchange chamber 19. An outlet pipe 23 is fixed to the outlet of the water pump 21, and one end of the outlet pipe 23 extends into the drying chamber shell 1 and is connected to the annular water pipe 24. When cooling down, the solenoid valve 47 on the second insulation pipe 17 and the exhaust pipe 18 is closed, and the solenoid valve 47 on the heat exchange pipe 20 is opened. Hot gas enters the heat exchange chamber 19 through the gas transfer ball 16. Inside, the hot air completes the heat conversion in the heat conversion box 19, heating the water inside the heat conversion box 19. The cooled gas then enters the annular air injection pipe 3, which can cool the inside of the drying chamber shell 1 and avoid the waste of heat energy caused by direct discharge. When the humidity is too high, the solenoid valve 47 on the second insulation pipe 17 and the heat exchange pipe 20 is closed, and the solenoid valve 47 on the exhaust pipe 18 is opened. At this time, the hot air carrying water vapor is discharged to the outside (the exhaust pipe 18 can discharge hot air and water vapor into the heat conversion box 19 to heat the water inside the heat conversion box 19, and can also be used as a heat source in other places to reduce heat energy consumption). When the temperature and humidity sensor 9 detects that the humidity inside the drying chamber shell 1 is insufficient, the water pump 21 is started. The water pump 21, which is heated by the hot air, is injected into the annular water pipe 24. The hot water is sprayed into the drying chamber shell 1 through the electromagnetic atomizing nozzle 25 to increase the humidity. The water sprayed is hot water, which avoids a large drop in temperature caused by increasing humidity.

[0042] Reference Figures 6-9The intelligent drying chamber also includes a uniform blooming structure set on the outer wall of the hollow fixed column 7. This structure ensures the black tea is evenly heated and blooms. The uniform blooming structure includes a cross-shaped bottom plate 26 rotatably fitted onto the outer wall of the hollow fixed column 7. A cross-shaped top plate 27 is rotatably connected to the inner top wall of the drying chamber shell 1, with the top of the hollow fixed column 7 penetrating through the cross-shaped top plate 27. The cross-shaped bottom plate 26 and the cross-shaped top plate 27 are coaxial. Multiple sliding rods 29 are fixedly connected between the cross-shaped bottom plate 26 and the cross-shaped top plate 27. The outer wall of the hollow fixed column 7 is rotatably fitted from top to bottom. There are multiple rotating rings 30, and the bottom ends of multiple sliding rods 29 are fixedly inserted through the rotating rings 30. Multiple support plates 31 are arranged in a ring on the outer wall of the rotating rings 30, and the top of each support plate 31 is slidably fitted with an arc-shaped hollow feeding plate 32. When the cross bottom plate 26 and cross top plate 27 rotate, they can drive the support plates 31 and the arc-shaped hollow feeding plate 32 to rotate. At this time, the hot air ejected from the air injection hole 4 and the air exhaust hole 8 is discharged from the outside to the inside and from the inside to the outside, respectively. The inside and outside work together to evenly dry and ferment the black tea placed on the arc-shaped hollow feeding plate 32.

[0043] Reference Figures 7-9 The uniformly patterned structure also includes a nut ring 46 sleeved on the outer wall of the hollow fixed column 7, and the nut ring 46 is located below the cross top plate 27. The top outer wall of the hollow fixed column 7 is provided with a reciprocating thread section 40, and the nut ring 46 is threadedly connected to the hollow fixed column 7 through the reciprocating thread section 40. The top of the cross bottom plate 26 is rotatably connected with multiple rotating rods 37. The cross top plate 27 is provided with multiple first rectangular holes 28, and the support plate 31 is provided with second rectangular holes 33. The top of the rotating rods 37 passes through multiple second rectangular holes 33 in sequence and extends into the first rectangular holes 28. The first rectangular holes 28 and the second rectangular holes 33 limit the rotation rods 37. The side of each of the multiple rotating rods 37 away from the hollow fixed column 7 is rotatably connected with a first connecting rod 38. The other end of each of the multiple first connecting rods 38 is rotatably connected to the corresponding arc-shaped hollow feeding plate 32. The multiple rotating rods 37 are close to the hollow Each side of the fixed column 7 is rotatably connected to a second connecting rod 39, and the top of each of the second connecting rods 39 is rotatably connected to a nut ring 46. The cross base plate 26, cross top plate 27, nut ring 46, and sliding rod 29 rotate. The nut ring 46 is threadedly connected to the reciprocating thread section 40. Therefore, during the rotation, the nut ring 46 moves up and down under the action of the reciprocating thread section 40. The reciprocating thread section 40 drives the rotating rod 37 to rotate back and forth through the second connecting rod 39. When the rotating rod 37 rotates outward, it pushes the arc-shaped hollow material feeding plate 32 outward through the first connecting rod 38. The multiple arc-shaped hollow material feeding plates 32 arranged vertically move outward a different distance under the action of the rotating rod 37. Therefore, the upward floating hot air can rise from the bottom of the arc-shaped hollow material feeding plate 32 to the black tea in the frame to make it bloom, avoiding the black tea from being vertically piled up and causing the black tea in the upper layer to not bloom evenly.

[0044] Reference Figures 7-9 The support plate 31 has multiple second arc-shaped blocks 36 on both sides of its top, and the arc-shaped hollow feeding plate 32 has multiple first arc-shaped blocks 35 on both sides of its bottom. The first arc-shaped blocks 35 cooperate with the second arc-shaped blocks 36. The bottom of the arc-shaped hollow feeding plate 32 is welded with a limiting block 34, which extends into the second rectangular hole 33 and cooperates with it. When the arc-shaped hollow feeding plate 32 moves, the cooperation of the first arc-shaped blocks 35 and the second arc-shaped blocks 36 causes the arc-shaped hollow feeding plate 32 to bounce up and down, thereby vibrating the black tea fixed in the frame of the arc-shaped hollow feeding plate 32, which facilitates the fermentation of the inner layer of black tea and achieves the purpose of uniform fermentation of black tea.

[0045] Reference Figure 8 A bevel gear ring 41 is bolted to the bottom of the cross base plate 26. A drive motor 42 is bolted to the bottom inner wall of the drying chamber shell 1. A bevel gear 43 that meshes with the bevel gear ring 41 is fixed to the output shaft of the drive motor 42. A temperature and humidity sensor 9 is bolted to the inner wall of one side of the drying chamber shell 1.

[0046] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8 The outer walls of the second insulation pipe 17, the exhaust pipe 18 and the heat exchange pipe 20 are all equipped with solenoid valves 47. A smart control panel 2 is provided on one side of the drying chamber shell 1. The smart control panel 2 is electrically connected to the solenoid valves 47, the drive motor 42, the water pump 21 and the electromagnetic atomizing nozzle 25.

[0047] The automatic detection system for black tea mold growth includes the aforementioned intelligent drying room for black tea mold growth.

[0048] Example 2

[0049] refer to Figure 10 Improvements based on Example 1: Multiple connecting plates 44 are fixed from top to bottom on one inner wall of the drying chamber shell 1, and the multiple connecting plates 44 are respectively located above adjacent support plates 31. A camera 45 is fixed to one side of the bottom of the connecting plate 44 by bolts. The camera 45 is electrically connected to the intelligent control panel 2. When the black tea on the arc-shaped hollow feeding plate 32 is fermenting, the arc-shaped hollow feeding plate 32 rotates under the action of the rotating rod 37 and the rotating ring 30 and moves back and forth, so as to evenly ferment the black tea. When the arc-shaped hollow feeding plate 32 moves to the outside, the camera 45 can clearly capture the video of the black tea fermenting, so that the staff can check the fermentation status of the black tea in real time.

[0050] The instructions for using the intelligent drying room for black tea to develop a blooming effect include the following steps:

[0051] S1. The frame containing black tea is fixed on the top of the arc-shaped hollow feeding plate 32. When it is necessary to increase the temperature inside the drying chamber shell 1 to ferment the black tea, the external connecting pipe 5 is connected to the heat source on the outer wall. The external hot air is injected into the annular air injection pipe 3 and the hollow fixed column 7 respectively. The air injection hole 4 and the exhaust hole 8 discharge the hot air from the outside to the inside and from the inside to the outside respectively to ferment the black tea placed in the frame on the arc-shaped hollow feeding plate 32. The operation of the exhaust fan 12 can discharge the upward floating hot air from the drying chamber shell 1 into the first heat preservation pipe 15 and the second heat preservation pipe 17 in sequence, and then into the annular air injection pipe 3, so as to circulate the hot air and avoid the waste of heat energy caused by direct discharge.

[0052] S2. The temperature and humidity inside the drying chamber shell 1 are monitored in real time by the temperature and humidity sensor 9. When it is necessary to cool down the inside of the drying chamber shell 1, the solenoid valve 47 on the second insulation pipe 17 and the exhaust pipe 18 is closed, and the solenoid valve 47 on the heat exchange pipe 20 is opened. The hot gas enters the heat conversion box 19 through the gas transfer ball 16. At this time, the hot gas completes the heat energy conversion in the heat conversion box 19, heats the water in the heat conversion box 19, and then the cooled gas enters the annular gas injection pipe 3, which can cool down the inside of the drying chamber shell 1 and avoid the waste of heat energy caused by direct discharge.

[0053] S3. When the temperature and humidity sensor 9 detects that the humidity inside the drying chamber shell 1 is too high, the solenoid valve 47 on the second insulation pipe 17 and the heat exchange pipe 20 is closed, and the solenoid valve 47 on the exhaust pipe 18 is opened. At this time, the hot air carrying water vapor is discharged to the outside (the exhaust pipe 18 can discharge the hot air and water vapor into the heat conversion box 19 to heat the water in the heat conversion box 19, and can also be used as a heat source in other places to reduce heat energy consumption). When the temperature and humidity sensor 9 detects that the humidity inside the drying chamber shell 1 is insufficient, the water pump 21 is started. The water pump 21, which is heated by the hot air at this time, is fed into the annular water pipe 24. The hot water is sprayed into the drying chamber shell 1 through the electromagnetic atomizing nozzle 25 to increase the humidity. The water sprayed is hot water, thereby avoiding a large drop in temperature caused by increasing humidity.

[0054] S4. During the fermentation process, the drive motor 42 drives the cross base plate 26, cross top plate 27, nut ring 46 and sliding rod 29 to rotate through the cooperation of the bevel ring 41 and bevel gear 43. The nut ring 46 is threadedly connected to the reciprocating thread section 40. Therefore, during the rotation, the nut ring 46 moves up and down under the action of the reciprocating thread section 40. The reciprocating thread section 40 drives the rotating rod 37 to rotate back and forth through the second connecting rod 39. When the rotating rod 37 rotates outward, it pushes the arc-shaped hollow feeding plate 32 outward through the first connecting rod 38. The multiple arc-shaped hollow feeding plates 32 arranged vertically move outward a different distance under the action of the rotating rod 37. Therefore, the upward floating hot air can ferment the black tea in the frame from the bottom of the arc-shaped hollow feeding plate 32, avoiding the vertical stacking of black tea and causing the black tea in the upper layer to not ferment evenly.

[0055] S5. In addition, when the arc-shaped hollow feeding plate 32 moves, the first arc-shaped block 35 and the second arc-shaped block 36 work together to make the arc-shaped hollow feeding plate 32 bounce up and down, thereby vibrating the black tea fixed in the frame of the arc-shaped hollow feeding plate 32, so as to facilitate the fermentation of the inner layer of black tea and achieve the purpose of uniform fermentation of black tea.

[0056] However, as is well known to those skilled in the art, the working principles and wiring methods of the intelligent control panel 2, solenoid valve 47, drive motor 42, camera 45, water pump 21 and electromagnetic atomizing nozzle 25 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
