Description

Technical Field

[0001] The invention relates to the technical field of tea production equipment, in particular to a temperature-adjustable tea drying machine. Background Art

[0002] Drying is the last step in tea processing and one of the key steps. The main purpose of drying is to dissipate the moisture of the tea to prevent over-fermentation and enhance the aroma of the tea. The main principle of drying is to continuously heat and dry the tea with high-temperature hot air to reduce the humidity of the tea to an appropriate level. Drying allows the tea to reach the appropriate humidity and taste, while locking in the aroma of the tea.

[0003] In daily life, tea is generally dried in a drawer-type tea dryer. The tea leaves are spread flat on a flat plate, which is then placed in the dryer and dried using charcoal or electric heating. As the temperature in the dryer rises from the bottom to the top, the tea leaves placed on the flat plate are dried and heated, thereby maintaining the moisture in the tea leaves and allowing them to be stored for a long time.

[0004] During actual operation, the temperature in the dryer gradually increases from the bottom to the top, which causes the temperature of the lower layer to be too high and the temperature of the upper layer to be too low. The temperature distribution inside the dryer is uneven. At the same time, the tea leaves placed on plates at different heights in the dryer require different drying times. The tea leaves on the plates closer to the top require longer drying times. When the dryer finishes drying, the tea leaves on the lower plates are over-dried and the tea leaves on the upper plates are under-dried, which leads to uneven drying of the tea leaves.

[0005] To this end, the existing technology provides some solutions, which include placing the tea leaves in a drum with a filter surface, and turning the drum to evenly dry the tea leaves with hot air, thereby solving the problem of uneven drying of the tea leaves. However, the temperature inside the drum cannot be adjusted, and the tea dust and tea residue generated during the turning of the tea leaves are not removed, which leads to reduced quality of the tea leaves.

[0006] In view of this, in order to overcome the above technical problems, the present invention designs a temperature-adjustable tea drying machine to solve the above technical problems. Summary of the Invention

[0007] The technical problem to be solved by the present invention is: how to eliminate tea dust and tea residues generated during tea drying and how to adjust the temperature for uniform tea drying.

[0008] In order to achieve the above object, the present invention proposes the following technical solutions:

[0009] The present invention provides a temperature-adjustable tea dryer, comprising a motor, a bracket, a housing, and a temperature sensor, and is characterized in that it also includes a flip assembly, an unfolding assembly, and a temperature adjustment assembly. The bracket is fixedly mounted on the ground, and the housing is fixedly mounted on the bracket. An air inlet is provided at the top of the left side of the housing, and an air outlet is provided at the bottom of the right side of the housing. A flip assembly for guiding is installed at the left end of the housing, and the flip assembly changes the position of the accumulated tea leaves by spatial rotation. The flip assembly is installed inside the housing, and is used to place tea leaves for drying. Hot air enters the drying interior from the air inlet provided on the housing. The flip assembly guides the hot air used for drying the tea leaves toward the right bottom of the dryer. The flip assembly flips the tea leaves. During the flipping process, the dried tea leaves will generate a large amount of tea residue and tea dust. The hot air guided by the flip assembly can guide the tea residue and tea dust generated during the flipping process to the right bottom of the dryer, thereby flipping the tea leaves so that the tea leaves are heated evenly, and the tea residue and tea dust generated during the drying process can be collected in a centralized manner.

[0010] The right side of the flip assembly is equipped with an unfolding assembly for assisting the flip assembly in screening tea leaves. The unfolding assembly converts left and right movement into up and down movement so that the tea leaves change position as the position of the unfolding assembly changes, thereby enabling the dried tea leaves to be taken out uniformly, thereby improving the convenience of taking out the tea leaves. The unfolding assembly is installed inside the flip assembly through the right side of the shell. When the dryer is working, when the flip assembly flips the tea leaves, if there is too much tea leaves, the tea leaves will accumulate, thereby causing the tea leaves to be heated unevenly. The unfolding assembly is installed inside the flip assembly to stir the tea leaves, thereby achieving uniform heating of the tea leaves. At the same time, the unfolding assembly can also The leaves are screened by size, and a temperature regulating component for exporting tea residues is installed under the expansion component. A temperature sensor is installed on the temperature regulating component, and the temperature regulating component is installed on the right bracket of the outer shell. When the dryer is working, the hot air is continuously transported to the inside of the dryer, causing the temperature inside the dryer to continue to rise. At this time, the temperature sensor drives the temperature regulating component to open and cool the dryer. When the temperature drops to a level suitable for drying tea leaves, the temperature regulating component is closed. When the temperature regulating component is opened, the tea residue and tea dust remaining in the dryer can be cleaned at the same time, thereby realizing the control of the temperature inside the dryer on the one hand, and the cleaning of the tea residue and tea dust in the dryer on the other hand.

[0011] The preferred turning assembly includes a motor, a drum and an auger, the motor is fixedly installed on the left and right sides of the shell, the output end of the motor passes through the left side of the shell and is connected to the drum, and a filter for hot air circulation is installed on the outer circumferential surface of the drum. The hot air used to dry the tea leaves enters the dryer through the air inlet opened in the shell and passes through the filter, thereby realizing the diffusion of the hot air and making the tea leaves in the drum evenly dried by the hot air, and an auger for conveying tea residue is fixedly installed on the outer circumferential surface of the drum. The auger will evenly guide the hot air entering the dryer so that the hot air moves in a certain direction, thereby realizing even drying of the tea leaves in the drum, and at the same time, the auger can also transport the tea residue and tea dust generated when the drum rotates, thereby realizing the transportation of the tea residue and preventing the tea residue from being over-dried and affecting the tea aroma. The auger and the shell are sealed to form a spiral channel, and the spiral channel can make the hot air evenly fill the entire dryer, avoiding the internal temperature of the dryer Inconsistency, thereby achieving uniform heating of the dryer interior, the spiral angle of the spiral auger fixedly installed on the outer circumferential surface of the drum is between 15°-30°, thereby reducing the blockage of tea residue on the one hand, and improving the efficiency of the auger in conveying tea residue on the other hand. When the hot air enters the dryer, the auger will guide the hot air entering the dryer, so that the hot air is evenly filled with the entire dryer, thereby achieving a uniform increase in the temperature inside the dryer. The spiral angle of the auger is less than 15°, which results in the spiral auger being unable to generate a large enough thrust during the transmission process, so that the tea residue is blocked in the middle of the spiral auger blades when rotating to convey the tea residue, thereby causing the drying of the drum tea to be affected by the tea residue and tea dust. The spiral angle of the auger is greater than 30°, which causes the tea residue and gas to be stuck on the side of the spiral, causing a blockage problem. The tea residue and gas are not pushed but slide on the spiral surface of the auger blades, thereby reducing the transmission efficiency.

[0012] The preferred unfolding assembly includes a handle, a baffle, a collecting bin, a connecting shaft, a paddle plate, a scraper, a fixed block, a connecting rod and a fixed frame, the connecting shaft is hollow, one end of the connecting shaft is fixedly connected to the baffle, one end of the baffle is fixedly installed with a handle, the connecting shaft is slidably installed inside the flip assembly, the staff can directly pull out the connecting shaft through the handle, thereby improving the installation convenience of the unfolding assembly, the other end of the connecting shaft is installed with a fixed frame supporting the scraper, a plurality of scrapers are slidably installed on the circumferential surface of the fixed frame, and the scrapers can stir the tea leaves at the bottom of the drum, and a fixed block for controlling the extension and retraction of the scraper to achieve the change of the position of the accumulated tea leaves is installed on the left side of the fixed frame, The scraper can be expanded and retracted on the fixed frame by moving the fixed block left and right, so that on the one hand, the tea leaves accumulated at the bottom of the drum can be stirred in the retracted state, and on the other hand, the tea leaves in the drum can be uniformly collected in the expanded state. A connecting rod is fixedly installed at one end of the fixed block close to the fixed frame, and a paddle is fixedly installed at the end of the connection away from the fixed block. The paddle is installed on the left side of the handle. When the staff presses the paddle and pulls out the connecting shaft, the scraper is in the expanded state, thereby realizing the scraper cleaning the inner wall of the flip assembly. A collection bin for screening tea leaves is fixedly installed on the connecting shaft, so that large and small leaves of tea can be screened during the rotation of the flip assembly.

[0013] Preferably, the fixed block is in the shape of a truncated cone, and an arc surface is provided at one end of the fixed block close to the connecting shaft, so that the scraper can be smoothly unfolded when the fixed block contacts the scraper, and an inclined surface that matches the fixed block is provided at the bottom end of the scraper close to the fixed frame. The arc surface on the fixed block is consistent with the inclination angle of the inclined surface at the bottom end of the scraper, so that the fixed block can fit tightly with the scraper when sliding left and right, ensuring smooth unfolding of the scraper and avoiding the scraper being stuck when the fixed block slides left and right, thereby preventing the scraper from being unable to unfold.

[0014] Preferably, the scrapers fixedly mounted on the fixed frame are evenly arranged at 60°, and the scrapers are staggered. There are six fixed scrapers, thereby ensuring that the scrapers are deployed to form a complete circle when the fixed block moves left and right. The scrapers are adapted to fit the inner wall of the drum by converting linear motion into up and down motion through the fixed block, thereby enabling the tea leaves inside the drum to be uniformly collected after drying. When the scrapers are retracted, since the scrapers are mounted inside the flip assembly, when the flip assembly flips the tea leaves, the scrapers cooperate with the flip assembly to stir the tea leaves, thereby achieving uniform drying of the tea leaves.

[0015] Preferably, the two side surfaces of the scraper perpendicular to the fixed frame are L-shaped, and the end of the scraper away from the fixed frame is a conical structure, and the bottom end of the cone fits with the inner wall of the drum, so that the conical structure can collect the tea leaves attached to the inner wall of the drum, and on the other hand, the tea leaves can be gathered near the conical structure for collection. After drying is completed, a brush is installed on the scraper, and the tea leaves in the flip assembly need to be taken out, and the scraper is unfolded. The evenly arranged scrapers are unfolded into a ring close to the inner wall of the flip assembly, and a brush is installed on the scraper. By taking out the unfolded assembly, the dried tea leaves in the flip assembly can be better taken out, and the brush on the scraper can clean the tea residue and tea dust remaining on the inner wall of the flip assembly. Preferably, the temperature regulating assembly includes a motor, a rotating shaft, a dust collecting trough, a rotating wheel, a rotating plate, a sleeve and a spring. The motor is controlled by a temperature sensor, so that when the temperature inside the dryer is too high or too low, the temperature sensor controls the motor to rotate. The output end of the motor is fixedly connected to the rotating shaft, and the other end of the rotating shaft away from the output end of the motor is fixedly installed with a rotating plate that blocks tea residue and hot air. The rotating plate is provided with a dust collecting trough for diversion near the bottom of the shell, so that the hot air inside the dryer can be discharged. The hot air and tea residue are transported to the dust collecting trough provided at the bottom of the shell through the flip assembly. The temperature inside the dryer gradually rises and reaches the threshold value of the temperature sensor. The temperature sensor will drive the motor to open the exhaust The tea residue and hot air rotating plate can be used to remove the tea residue in the dust collecting trough. A rotating wheel is installed in the middle of the rotating shaft, and the rotating wheel is installed at 1 / 3 of the transmission shaft. An incomplete annular protrusion is provided at the end of the rotating wheel away from the axis. An arc-shaped groove is provided at the lower end of the baffle, and the annular arc groove cooperates with the rotating wheel protrusion, so that the rotating wheel can slide in the annular arc groove. The arc protrusion cooperates with the arc groove to realize the change of the expansion component position, so that the tea leaves inside the drum can be stirred when the temperature is adjusted so that the tea leaves inside the drum are heated evenly. A sleeve is detachably installed on the left end of the baffle, and the baffle and the sleeve are connected by a spring, so that the convenience of disassembling the baffle can be improved.

[0016] Preferably, a conical protrusion is fixedly installed inside the drum, which can cooperate with the unfolding component to stir the tea leaves inside the drum, thereby achieving uniform heating of the tea leaves accumulated inside the drum, thereby improving the quality of the tea leaves. The annular array of conical protrusions is at the circumference of the collection bin, and the conical protrusions are hinged to the inside of the drum, so that when the unfolding component collects the tea leaves, the conical protrusions will not affect the unfolding component. The conical protrusions use the rotation of the drum to change the position of smaller tea leaves, thereby achieving the screening and collection of large and small tea leaves.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention provides a temperature-adjustable tea dryer. The device changes the direction of hot air by rotating in space and utilizing a flip component. The unfolding component flips the component to stir the tea leaves, thereby achieving uniform heating of the tea leaves and centralized collection of tea residues.

DETAILED DESCRIPTION

[0031] Example: Figure 1-8 As shown, a temperature-adjustable tea dryer provided by the present invention includes a temperature-adjustable tea dryer provided by the present invention, including a motor 41, a bracket 1, a shell 2, and a temperature sensor 3, characterized in that it also includes a flip component 4, an unfolding component 5 and a temperature adjustment component 6, the bracket 1 is fixedly installed on the ground, the shell 2 is fixedly installed on the bracket 1, an air inlet is opened at the top of the left side of the shell 2, and an air outlet is opened at the bottom of the right side of the shell 2. A flip component 4 for guiding is installed at the left end of the shell 2, and the flip component 4 is installed inside the shell 2. The flip component 4 is used to place tea leaves for drying, and hot air enters the drying interior from the air inlet opened on the shell 2. The flip component 4 guides the hot air used to dry the tea leaves to the right bottom of the dryer. The flip component 4 flips the tea leaves. During the flipping process, the dried tea leaves will produce a large amount of tea residue and tea dust. The hot air guided by the flip component 4 can guide the tea residue and tea dust generated during the flipping process to the right bottom of the dryer, thereby realizing the flipping of the tea leaves so that the tea leaves are heated evenly, and at the same time, the tea residue and tea dust generated during the drying process can be collected centrally.

[0032] The right side of the flip assembly 4 is equipped with an expansion assembly 5 for assisting the flip assembly 4 in screening tea leaves. The expansion assembly 5 is installed inside the flip assembly 4 through the right side of the shell 2. When the dryer is working, when the flip assembly 4 flips the tea leaves, when the amount of tea leaves is too much, the tea leaves will accumulate, which will lead to uneven heating of the tea leaves. The expansion assembly 5 is installed inside the flip assembly 4 to stir the tea leaves, thereby achieving uniform heating of the tea leaves. At the same time, the expansion assembly 5 can also screen the tea leaves according to size. A temperature control assembly 6 for exporting tea residues is installed below the expansion assembly 5. A temperature sensor 3 is installed on the temperature control assembly 6. The temperature control assembly 6 is installed at the right side bracket 1 of the shell 2. When the dryer is working, the hot air is continuously transported to the inside of the dryer, resulting in a continuous increase in the temperature inside the dryer. At this time, the temperature sensor 3 drives the temperature control assembly 6 to open and cool the dryer. When the temperature drops to a level suitable for drying tea leaves, the temperature control assembly 6 is closed. When the temperature control assembly 6 is opened, the tea residue and tea dust remaining in the dryer can be cleaned at the same time, thereby achieving on the one hand the control of the temperature inside the dryer and on the other hand the cleaning of the tea residue and tea dust in the dryer.

[0033] When the staff operates the dryer to dry tea leaves, they take out the unfolding component 5 and place the tea leaves in the flipping component 4, so that the flipping component 4 can dry the tea leaves evenly. At the same time, the hot air passes through the flipping component 4 to evenly heat the inside of the dryer. By cooperating with the unfolding component 5 and the flipping component 4, the unfolding component 5 will stir the tea leaves in the flipping component 4 again during the rotation process, so as to achieve double stirring to make the tea leaves heated evenly. At the same time, the unfolding can also screen the large and small leaves of the tea leaves in the flipping component 4, so as to improve the overall quality of the tea leaves. By cooperating with the temperature regulating component 6, the internal temperature of the dryer can be adjusted to screen and filter the tea residues generated during the tea drying process, so as to reduce the influence of temperature and tea residues on the drying of the tea leaves. After the drying is completed, the staff will take out the unfolding component 5, and the unfolding component 5 can clean the tea residues and tea dust remaining on the flipping component 4, so as to ensure a good drying environment for the next drying.

[0034] The prior art dryer generally adopts a drum 42 type, and the tea leaves are placed in the drum 42 for drying. The tea leaves are easily accumulated at the bottom of the drum 42, and the inside and outside of the accumulated tea leaves are heated unevenly, which affects the overall quality of the tea leaves. At the same time, it is also impossible to adjust the overall temperature inside the dryer. However, the present application cooperates with the flip component 4, the unfolding component 5, and the temperature control component 6, so that during the drying process, the temperature inside the dryer is adjusted while the tea residue produced by the tea leaves is separated, filtered and discharged, thereby reducing the impact of the tea residue on the tea leaves, thereby improving the overall taste and quality of the tea leaves.

[0035] The turning assembly 4 includes a motor 41, a drum 42 and an auger 43. The motor 41 is fixedly installed on the left and right sides of the shell 2. The output end of the motor 41 passes through the left side of the shell 2 and is connected to the drum 42. A filter for hot air circulation is installed on the outer circumference of the drum 42. When the drum 42 rotates, the filter can also filter the tea residue produced by drying the tea leaves to the bottom of the shell 2, thereby reducing the influence of the tea residue on the quality of the tea leaves. The hot air used to dry the tea leaves enters the dryer through the air inlet opened in the shell 2 and passes through the filter, thereby realizing the diffusion of the hot air so that the hot air can evenly dry the tea leaves in the drum 42. An auger 43 for conveying tea residue is fixedly installed on the outer circumference of the drum 42. The auger 43 will evenly guide the hot air entering the dryer, so that the hot air moves in a certain direction, thereby realizing the even drying of the tea leaves inside the drum 42. Drying, at the same time, the auger 43 can also transport the tea residue and tea dust generated by the rotation of the drum 42. After the hot air enters the dryer, a part of the hot air will pass through the filter and enter the inside of the drum 42, and then the tea leaves inside the drum 42 are evenly dried. At the beginning of drying, since the auger 43 is fixedly installed on the circumferential surface of the drum 42, tea residue and tea dust will be generated during the rotation. The tea residue will be driven to the bottom of the right side of the dryer by the rotation of the auger 43, and the tea dust will be brought to the right side of the dryer with the flow direction of the hot air, thereby realizing the transportation of the tea residue and preventing the tea residue from being over-dried and affecting the tea aroma. Since the dryer is in the shape of left and right drums 42, the auger 43 and the shell 2 are sealed to form a spiral channel, and the spiral channel can make the hot air evenly fill the entire dryer, avoiding inconsistent temperatures on the left and right sides of the dryer, thereby achieving uniform heating inside the dryer.

[0036] The spiral angle of the spiral auger 43 fixedly installed on the outer circumferential surface of the drum 42 is between 15° and 30°. The drum 42 rotates the auger 43 to transport the tea residue screened by the drum 42, thereby reducing the blockage of the tea residue and improving the efficiency of the auger 43 in transporting the tea residue. During the drying process, the auger 43 will guide the hot air entering the dryer, so that the hot air is evenly filled with the entire interior of the dryer, thereby achieving a uniform increase in the temperature inside the dryer. The spiral angle of the auger 43 is less than 15°, which results in the spiral auger 43 being unable to generate a sufficiently large thrust during the transmission process, so that the tea residue is blocked in the middle of the spiral auger 43 blades when the tea residue is rotated to be transported, thereby causing the drying of the tea leaves on the drum 42 to be affected by the tea residue and tea dust. The spiral angle of the auger 43 is greater than 30°, which causes the tea residue and gas to be stuck on the side of the spiral, causing a blockage problem. The tea residue and gas are not pushed but slide on the spiral surface of the auger 43 blades, thereby reducing the transmission efficiency.

[0037] The unfolding assembly 5 includes a handle 51, a baffle 52, a collecting bin 53, a connecting shaft 54, a paddle 55, a scraper 56, a fixing block 57, a connecting rod and a fixing frame 59. The connecting shaft 54 ​​is hollow, and one end of the connecting shaft 54 ​​is fixedly connected to the baffle 52. One end of the baffle 52 is fixedly installed with a handle 51. The connecting shaft 54 ​​is slidably installed inside the flip assembly 4. The staff can directly pull out the connecting shaft 54 ​​through the handle 51. The other end of the connecting shaft 54 ​​is installed with a fixing frame 59 supporting the scraper 56. A number of scrapers 56 are slidably installed on the circumferential surface of the fixing frame 59, and the scraper 56 can stir the tea leaves at the bottom of the drum 42. When the scraper 56 is working, the spring 66 is in a stretched state. The scraper 56 completes its work. After that, it can be retracted by spring 66. A fixed block 57 for changing the working state of the scraper 56 is installed on the left side of the fixed frame 59. The scraper 56 can be expanded and retracted on the fixed frame 59 by moving the fixed block 57 left and right. A connecting rod is fixedly installed on one end of the fixed block 57 close to the fixed frame 59, and a dial plate 55 is fixedly installed on the end connected to the end away from the fixed block 57. The dial plate 55 is installed on the left side of the handle 51. When the staff presses the dial plate 55 and pulls out the connecting shaft 54, the scraper 56 is in the expanded state, thereby realizing that the scraper 56 cleans the inner wall of the flip assembly 4. A collecting bin 53 for screening tea leaves is fixedly installed on the connecting shaft 54, so that the large and small leaves of tea leaves can be screened during the rotation of the flip assembly 4.

[0038] Before drying begins, the staff will place the unfolding component 5 into the drum 42. At this time, the scraper 56 on the connecting shaft 54 ​​is in a retracted state. The drum 42 can be used to stir the tea leaves when drying, so that the tea leaves will not accumulate and the internal temperature will not be too high, thereby achieving uniform drying of the tea leaves. During drying, the drum 42 rotates continuously, and the collection bin 53 on the connecting shaft 54 ​​will collect tea leaves with small leaves, thereby achieving the screening and collection of large and small tea leaves. After drying is completed, the staff needs to press the dial plate 55 to unfold the scraper 56, and the scraper 56 will press against the inner wall of the drum 42. When the staff pulls out the unfolding component 5, the scraper 56 will scrape out the tea leaves. At the same time, the scraper 56 will clean the tea residue and tea dust remaining on the inner wall filter of the drum 42, thereby ensuring a good drying environment for the next drying of the tea leaves.

[0039] The fixed block 57 is in the shape of a truncated cone, and an arc surface 571 is provided at one end of the fixed block 57 close to the connecting shaft 54, so that the scraper 56 can be smoothly unfolded when the fixed block 57 contacts the scraper 56. The scraper 56 is provided with an inclined surface 561 that cooperates with the fixed block 57 near the bottom end of the fixed frame 59. The arc surface 571 provided on the fixed block 57 and the inclined surface 561 provided at the bottom end of the scraper 56 have the same inclination angle, so that the fixed block 57 can fit closely with the scraper 56 when sliding left and right, ensuring the smooth unfolding of the scraper 56 and avoiding the scraper 56 being stuck by the fixed block 57 when sliding left and right, thereby preventing the scraper 56 from being unfolded.

[0040] The fixed block 57 is in a frustum shape, so that it can fit tightly with the scraper 56 when the fixed block 57 slides left and right. When the staff places the unfolding component 5, the fixed block 57 does not move. At this time, the scraper 56 is in a retracted state. After the drying is completed, the staff needs to press the paddle. At this time, the fixed block 57 is driven to the right by the connecting rod, and the scraper 56 is in an unfolded state and close to the inner wall of the drum 42. The scraper 56 is in a fan shape with a protrusion. When the flip component 4 dries the tea leaves during the rotation process, the scraper 56 is in a retracted state. Since there is a protrusion on the scraper 56, it can cooperate with the flip component 4 to stir the tea leaves so that the tea leaves are heated evenly. After the drying is completed, the staff needs to take out the tea leaves, and the scraper 56 is in an unfolded state. The protrusion can fit the inner wall of the flip component 4, thereby realizing that the scraper 56 cleans the tea residue and tea dust remaining on the inner wall of the flip component 4.

[0041] Six scrapers 56 are fixedly mounted on the fixed frame 59 and are evenly arranged at 60° intervals. A brush is installed on the scraper 56. When the scraper 56 is in the retracted state, since the scraper 56 is installed inside the flip assembly 4, when the flip assembly 4 flips the tea leaves, the scraper 56 cooperates with the flip assembly 4 to stir the tea leaves, thereby preventing the tea leaves from accumulating at the bottom of the drum 42, causing the internal temperature to be too high and affecting the quality of the tea leaves, thereby achieving uniform drying of the tea leaves. After the drying is completed, the tea leaves in the flip assembly 4 need to be taken out, and the scraper 56 is unfolded. The six scrapers 56 evenly arranged at 60° are unfolded into a ring that is close to the inner wall of the flip assembly 4. At the same time, a brush is installed on the ring. By taking out the unfolding assembly 5, the dried tea leaves in the flip assembly 4 can be taken out, and the brush on the scraper 56 can clean the tea residue and tea dust remaining on the inner wall of the flip assembly 4.

[0042] The two side surfaces of the scraper 56 perpendicular to the fixing frame 59 are L-shaped, and the end of the scraper 56 away from the fixing frame 59 is a conical structure, and the bottom end of the cone fits with the inner wall of the drum 42, so that the conical structure can collect the tea leaves attached to the inner wall of the drum 42, and on the other hand, the tea leaves can be gathered near the conical structure for collection. After the drying is completed, a brush is installed on the scraper 56, and the tea leaves in the flip assembly 4 need to be taken out. The scraper 56 is unfolded, and the evenly arranged scrapers 56 are unfolded into a ring close to the inner wall of the flip assembly 4. At the same time, a brush is installed on the scraper 56. By taking out the unfolding assembly 5, the dried tea leaves in the flip assembly 4 can be better taken out, and the brush on the scraper 56 can clean the tea residue and tea dust remaining on the inner wall of the flip assembly 4.

[0043] The temperature regulating assembly 6 comprises a motor 68, a rotating shaft 61, a dust collecting trough 62, a rotating wheel 63, a rotating plate 64, a sleeve 65 and a spring 66. The motor 68 is controlled by the temperature sensor 3, so that when the temperature inside the dryer is too high or too low, the temperature sensor 3 controls the motor 68 to rotate. The output end of the motor 68 is fixedly connected to the rotating shaft 61, and the other end of the rotating shaft 61 away from the output end of the motor 68 is fixedly installed with a rotating plate 64 for blocking tea residue and hot air. The rotating plate 64 is provided with a dust collecting trough 62 for diversion near the bottom of the shell 2, so that the hot air inside the dryer can be discharged. The hot air and tea residue are transported to the dust collecting trough 62 provided at the bottom of the shell 2 through the flip assembly 4. The internal temperature of the dryer gradually rises and reaches the threshold value of the temperature sensor 3. The temperature sensor 3 will drive the motor 68 to open the rotating plate to remove the tea residue and hot air. The movable plate 64 can remove the tea residue in the dust collecting trough 62 on the one hand, and refresh the air environment inside the dryer on the other hand. A rotating wheel 63 is installed in the middle of the rotating shaft 61, and the rotating wheel 63 is installed on the transmission shaft. An incomplete annular protrusion is provided at the end of the rotating wheel 63 away from the axis, and an arc-shaped groove 67 is provided at the lower end of the baffle 52. The annular arc groove cooperates with the protrusion of the rotating wheel 63, so that the rotating wheel 63 can slide in the annular arc groove, and the arc protrusion 631 cooperates with the arc-shaped groove 67 to realize the change of the position of the unfolding component 5, so that the tea leaves inside the drum 42 can be stirred when the temperature is adjusted so that the tea leaves inside the drum 42 are heated evenly. A sleeve 65 is detachably installed on the left end of the baffle 52, and the baffle 52 and the sleeve 65 are connected by a spring 66, so that the convenience of disassembling the baffle 52 can be improved.

[0044] During the drying process, the turning assembly 4 cooperates with the temperature regulating assembly 6, and the drum 42 rotates to dry the tea leaves, which will produce tea residue and tea dust. The hot air will bring the tea dust into the integrated groove of the dryer through the rotation of the auger 43, and the tea residue will be brought into the dust collecting groove 62 of the dryer by the rotating auger 43. The increasing amount of hot air will make the temperature inside the dryer too high. When a certain threshold is reached, the temperature sensor 3 starts the motor 68 to open the rotating plate 64 that blocks the tea residue and hot air, thereby discharging the accumulated tea residue on the one hand and regulating the temperature inside the dryer on the other hand. Adjust and refresh the environment inside the dryer. Through the cooperation of the temperature adjustment component 6 and the expansion component 5, when the temperature sensor 3 drives the motor 68 to rotate to discharge impurities inside the dryer, the incomplete annular protrusion on the rotating wheel 63 slides in the incomplete arc-shaped slide groove 67 opened at the lower end of the baffle 52, so that the baffle 52 drives the connecting shaft 54 ​​to move left and right, and then the tea leaves in the collection bin 53 on the connecting shaft 54 ​​can be filtered for the second time. Tea residue and tea dust. When the baffle 52 moves to the right, it can be reset by the spring 66 installed on the sleeve 65.

[0045] The ratio of the diameter of the sleeve 65 to that of the baffle 52 is:, and on the one hand, an incomplete annular groove is provided at the lower end of the baffle 52 to provide a working distance during operation, and on the other hand, the sealing of the dryer is improved. An incomplete arc groove 67 is provided at the lower end of the baffle 52, and the annular arc groove cooperates with the protrusion of the rotating wheel 63, so that the rotating wheel 63 can slide in the annular arc groove, and the protrusion of the rotating wheel 63 slides in the annular groove. Due to the height difference between the annular protrusion and the arc groove 67, the connecting shaft 54 ​​can produce a large rebound when it is reset, so that on the one hand, the connecting shaft 54 ​​can be moved left and right, and on the other hand, the tea leaves inside the collection bin 53 on the connecting shaft 54 ​​can be vibrated and filtered for tea residue.

[0046] A conical protrusion is fixedly installed inside the drum 42, which can cooperate with the unfolding component 5 to stir the tea leaves inside the drum 42, thereby achieving uniform heating of the tea leaves accumulated inside the drum 42, thereby improving the quality of the tea leaves. The annular array of conical protrusions is at the circumference of the collecting bin 53, and the conical protrusions are hinged to the inside of the drum 42, so that when the unfolding component 5 collects the tea leaves, the conical protrusions will not affect the unfolding component 5. The conical protrusions use the rotation of the drum 42 to change the position of smaller tea leaves, thereby achieving the screening and collection of large and small tea leaves.

[0047] Before drying tea leaves, the staff first needs to place the tea leaves in the drum 42 of the turning assembly 4, and then put the unfolding assembly 5 into the drum 42. At this time, the scraper 56 is in the retracted state, and the drum 42 is started. The auger 43 on the drum 42 guides the hot air, so that the temperature inside the dryer is quickly raised. At the same time, when the drum 42 rotates, the dried tea leaves will produce tea residue and tea dust. The produced tea residue will be driven by the auger 43 to the dust collecting tank 62 on the right side of the dryer. The produced tea dust will be driven by the hot air through the auger 43 and gather on the right side of the dryer. When the temperature inside the dryer is too high, the temperature sensor 3 controls The motor 68 opens the rotating plate 64 of the integrated groove. Driven by the hot air, the tea residue and tea dust generated will be discharged from the dryer. At the same time, the discharge of hot air can cool the inside of the dryer. When the temperature is too low, the temperature sensor 3 controls the motor 68 to close the rotating plate 64. After the drying is completed, the staff needs to press the dial plate 55 to pull out the connecting shaft 54. When pressing the dial plate 55, the dial plate 55 will drive the connecting rod to pull the fixed block 57 to move to the right, so that the scraper 56 is unfolded and close to the inner wall of the drum 42. While pulling it out, the tea residue and tea dust remaining on the inner wall of the drum 42 are cleaned to ensure a good drying environment for the next drying of tea leaves.
