Description

Technical Field

[0001] This invention relates to the field of tea-making equipment technology, specifically to an integrated vortex thermal crusher for tea-making. Background Technology

[0002] As a semi-finished product preceding matcha processing, the quality of tencha directly affects the color and flavor of the final matcha product. In the tencha production process, the vortex heat crushing process is one of the key steps. This process uses high-temperature hot air to quickly dehydrate and color-fix the tea leaves after fixation, and uses ultra-hot air forming technology to quickly lock in the color of the tea leaves. Currently, the hot air inlet of the vortex heat crushing equipment usually adopts a fixed cross-section guide structure to introduce hot air into the drying cylinder. This structure includes a single air inlet and a fixed flow distribution component. After passing through this structure, the high-temperature hot air directly enters the drying cylinder and comes into contact with the tea leaves.

[0003] However, in actual production, factors such as changes in hot air duct resistance, fluctuations in fan outlet pressure, and changes in airflow density caused by changes in hot air temperature result in undesirable fluctuations in the hot air velocity and flow field morphology entering the drying cylinder, even at the same production line speed (i.e., the same tea feed rate). Existing fixed-section guide structures cannot effectively compensate for and stabilize these hot air fluctuations, leading to some tea leaves being overheated and becoming dull or charred during the thermal crushing process, while others are undercooked and have a greenish tint. The consistency of the thermal crushing effect within the same batch of tea is difficult to guarantee, ultimately affecting the uniformity of the finished tea product's quality. Therefore, we propose an integrated vortex-energy thermal crushing device for tea production.

[0005] The purpose of this invention is to provide an integrated vortex-powered thermal crushing device for tea grinding production, to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: An integrated vortex-powered thermal crushing device for tea grinding production, comprising a vortex crushing cylinder and a drying cylinder, and further comprising: The connecting cylinder is fixedly installed between the vortex crusher and the drying cylinder, and is used to send hot air and tea leaves into the drying cylinder; The feed pipe is fixedly installed at the top of the vortex crusher and is used to feed tea leaves into the vortex crusher. The airflow regulation unit is located inside the vortex crusher and is used to evenly disperse the hot airflow sent into the vortex crusher and ensure that it comes into full contact with the tea leaves. The airflow tuning unit includes: The floating vortex module is located at the end of the vortex crusher away from the connecting cylinder, and is used to change the area of ​​the air inlet throat of the vortex crusher according to the flow fluctuation. The baffle temperature equalization module is located at the center of the vortex crusher and is used to baffle and evenly distribute the airflow passing through the vortex crusher. The tea-dispersing module is located inside the vortex crusher near the connecting cylinder and is used to disperse the tea leaves fed into the feed pipe.

[0006] Preferably, an air supply pipe is fixedly installed at the end of the vortex crusher away from the connecting cylinder, and a discharge pipe is fixedly installed at the end of the drying cylinder away from the connecting cylinder. Multiple sets of supports are fixedly installed on the outer walls of the vortex crusher and the drying cylinder.

[0007] Preferably, the floating vortex module includes: A ring frame is fixedly installed on the inner wall at the center of the vortex crusher. A rotating rod is rotatably installed through the center of the ring frame to provide the installation anchor point for the entire airflow tuning unit. The guide cone is sleeved on the end of the rotating rod near the air supply pipe and is used to change the area of ​​the throat between the air supply pipe and the vortex crusher. Spiral grooves are formed on the outer arc surface of the guide cone to cooperate with the airflow to drive the guide cone to rotate; A guide belt is fixedly installed on the outer arc surface of the rotating rod. The inner wall of the guide cone is provided with a guide groove that slides with the guide belt to restrict the guide cone to slide only along the axial direction of the rotating rod. An annular groove is formed at the end of the guide cone. A connecting ring is rotatably installed on the inner wall of the annular groove. The side wall of the connecting ring is connected to one side of the annular frame by three sets of elastic elements arranged in a circumferential array, which are used to push the guide cone to reset along the axial direction of the rotating rod.

[0008] Preferably, the elastic element includes: The fixing sleeve is fixedly installed on the side wall at the center of the ring frame to provide an anchor point for the installation of the elastic element; The slide rod is fixedly installed on one side of the connecting ring, and the slide rod is slidably connected to the fixed sleeve for sliding along the axial direction of the fixed sleeve; A spring is fixedly installed between the end of the slide rod and the inner wall of the fixed sleeve, and is used to push the slide rod and the connecting ring to reset.

[0009] Preferably, the guide cone includes a large-diameter end and a small-diameter end, the small-diameter end of the guide cone is located near the side of the air supply pipe, and the diameter of the large-diameter end is smaller than the inner diameter of the air supply pipe.

[0010] Preferably, the baffle temperature equalization module includes: The sun gear is fixedly installed on the outer wall of the rotating rod. Planet gears are rotatably installed on the side wall of the annular frame. A rotating cylinder is rotatably installed on the side wall of the annular frame. A planet carrier is fixedly installed on the inner wall of the rotating cylinder to cooperate with the rotation of the rotating rod to form a planetary gear set. The flow equalization plate is fixedly installed on the outer wall of the rotating drum. Several through holes are opened on both sides of the flow equalization plate to cooperate with the rotation of the planetary gear set to evenly distribute the airflow in the vortex crusher in the circumference. A hollow cavity, located inside the flow equalization plate, serves as a buffer for airflow. A convex ring is fixedly installed on the leeward side of the flow equalization plate. Several side holes are distributed in a circumferential array on the arc-shaped inner surface of the convex ring for radial dispersion of airflow inside the vortex crusher.

[0011] Preferably, the axes of the side hole and the through hole are perpendicular to each other, and the inside of the convex ring is hollow, with the internal cavity of the convex ring communicating with the hollow cavity.

[0012] Preferably, the through holes on the windward and leeward sides of the flow equalization plate are staggered.

[0013] Preferably, the dispersing module includes: A retaining ring is fixedly installed on the outer wall of the end of the rotating rod and is used to rotate synchronously with the rotation of the rotating rod. Three sets of curved plates are fixedly installed on the outer wall of the fixed ring in a circular array to disperse the tea leaves falling from above as the fixed ring rotates. Several raised strips are evenly distributed on the surface of the curved plate to help disperse the clumps of tea leaves.

[0014] Preferably, the surface of the bent plate is inclined to the axis of the fixed ring, and the bent plate is S-shaped.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting a floating vortex module, sleeves a guide cone on a rotating rod and uses an elastic element to provide a restoring force. At the same time, a spiral groove is opened on the outer arc surface of the guide cone. When the hot air flow fluctuates, the airflow impact force on the guide cone changes accordingly, automatically overcoming or releasing the elastic force of the elastic element and sliding along the axial direction of the rotating rod. This allows the annular throat area between the outer wall of the guide cone and the inner wall of the air supply pipe to adaptively adjust with the flow fluctuation, thereby maintaining a relatively stable hot air velocity entering the vortex crusher. This reduces the instability of the hot air flow field caused by factors such as changes in hot air pipe resistance and fluctuations in fan outlet pressure, improves the anti-disturbance capability of the hot air delivery process, and solves the problem that existing fixed cross-section guide structures cannot effectively compensate for hot air fluctuations, resulting in inconsistent thermal crushing effects.

[0016] This invention also incorporates a flow equalization module. The rotating rod drives the sun gear, which in turn drives the planetary carrier and rotating drum at a speed lower than the rotating rod. This causes the flow equalization disk to rotate synchronously with the rotating drum. When hot air passes through the staggered through-holes on both sides of the flow equalization disk, it is forced to change direction and be buffered within the hollow cavity. Simultaneously, some hot air is injected radially through the side holes on the convex ring. This creates a uniform flow field with axial and radial cross-mixing on the cross-section of the vortex crusher, eliminating potential temperature differences between the center and edge of the hot air. This ensures a consistent temperature distribution of the hot air entering the drying drum across the entire cross-section, solving the problem of uneven heating of the same batch of tea leaves due to uneven hot air distribution within the vortex crusher.

[0017] This invention also incorporates a dispersing module. The rotation of the rotating rod drives the curved plate on the fixed ring to rotate synchronously, causing the tea leaves falling into the vortex crusher from the feed pipe to be periodically patted by the curved plate. At the same time, the convex strips on the surface of the curved plate further scrape and tear the sticky tea clumps. The inclined setting of the curved plate allows it to also have a component force that pushes the tea leaves axially when rotating. The S-shaped structure allows the same curved plate to have different tangential inclination angles at different radial positions, realizing multi-angle dispersion of the falling tea leaves. This ensures that the tea leaves are in a loose and uniform distribution state before entering the hot air zone, solving the problems of insufficient contact between the tea leaves and the hot air when the tea leaves are fed in clumps, and insufficient heat breaking of some tea leaves due to wrapping.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-6 This invention provides a technical solution: an integrated vortex thermal crushing device for tea grinding production, comprising a vortex crushing cylinder 1 and a drying cylinder 3, and further comprising: Connecting cylinder 2 is fixedly installed between vortex crusher 1 and drying cylinder 3, and is used to send hot air and tea into drying cylinder 3; Feed pipe 4 is fixedly installed on the top of vortex crusher 1 and is used to feed tea into vortex crusher 1; The airflow adjustment unit 8 is located inside the vortex crusher 1 and is used to evenly disperse the hot airflow sent into the vortex crusher 1 and make it fully contact the tea leaves. The airflow tuning unit 8 includes: The floating swirl module 81 is located at the end of the vortex crusher 1 away from the connecting cylinder 2, and is used to change the air inlet throat area of ​​the vortex crusher 1 according to the flow fluctuation. The deflector temperature equalization module 82 is located at the center of the vortex crusher 1 and is used to deflect and evenly distribute the airflow flowing through the vortex crusher 1. The tea-dispersing module 83 is located inside the vortex crusher 1 near the connecting cylinder 2 and is used to disperse the tea leaves fed into the feed pipe 4.

[0022] Both the vortex crusher 1 and the drying cylinder 3 are horizontally arranged cylindrical structures, coaxially connected by a connecting cylinder 2, allowing hot air and tea leaves to enter the drying cylinder 3 in a straight line from the vortex crusher 1. The air supply pipe 5 delivers high-temperature superheated air from an external hot air source axially into the vortex crusher 1. The feed pipe 4 is located at the top of the vortex crusher 1, used to feed the withered tea leaves into the inner cavity of the vortex crusher 1 from top to bottom. The airflow regulation unit 8 is installed inside the vortex crusher 1, used to regulate the flow field of the high-temperature hot air delivered by the air supply pipe 5, ensuring that the hot air enters the drying cylinder 3 in a uniform and stable manner.

[0023] The floating vortex module 81 is located near the air supply pipe 5 and can adaptively change the throat cross-sectional area of ​​the air inlet channel according to the flow rate of hot air input from the air supply pipe 5. At the same time, it initially disperses the hot air and gives it circumferential rotational momentum. The baffle temperature equalization module 82 is located in the middle area of ​​the vortex crusher 1. It is used to receive the rotating hot air output from the floating vortex module 81 and evenly disperse it across the entire cross-section of the cylinder, eliminating local temperature differences. The dispersing module 83 is located near the connecting cylinder 2 and below the feed pipe 4. It is used to disperse the tea leaves into a loose state. After the hot air flows through the floating vortex module 81 and the baffle temperature equalization module 82 in sequence, it reaches the area where the dispersing module 83 is located in a uniform flow field. It carries the tea leaves dispersed by the dispersing module 83 through the connecting cylinder 2 into the drying cylinder 3.

[0024] An air supply pipe 5 is fixedly installed at the end of the vortex crusher 1 away from the connecting cylinder 2, and a discharge pipe 6 is fixedly installed at the end of the drying cylinder 3 away from the connecting cylinder 2. Multiple sets of brackets 7 are fixedly installed on the outer walls of the vortex crusher 1 and the drying cylinder 3.

[0025] The air supply pipe 5 is connected to an external hot air source and serves as the inlet for high-temperature hot air. The discharge pipe 6 serves as the outlet for the tea leaves and exhaust gas after the thermal crushing process. Multiple sets of supports 7 are arranged at intervals along the axial direction of the vortex crusher 1 and the drying cylinder 3 to support the two cylinders at the same horizontal height and ensure the coaxiality of the entire production line.

[0026] Please see Figures 3-4 The floating vortex module 81 includes: The annular frame 811 is fixedly installed on the inner wall of the center of the vortex crusher 1. A rotating rod 812 is rotatably installed through the center of the annular frame 811 to provide the installation anchor point for the entire airflow tuning unit 8. The guide cone 815 is sleeved on the end of the rotating rod 812 near the air supply pipe 5 and is used to change the throat area between the air supply pipe 5 and the vortex crusher 1. Spiral groove 819 is formed on the outer arc surface of guide cone 815 to cooperate with airflow to drive guide cone 815 to rotate; The guide belt 817 is fixedly installed on the outer arc surface of the rotating rod 812. The inner wall of the guide cone 815 is provided with a guide groove 818 that slides with the guide belt 817 to restrict the guide cone 815 to slide only along the axial direction of the rotating rod 812. An annular groove 816 is formed at the end of the guide cone 815. A connecting ring 814 is rotatably mounted on the inner wall of the annular groove 816. The side wall of the connecting ring 814 is connected to one side of the annular frame 811 by three sets of elastic members 813 arranged in a circumferential array, which are used to push the guide cone 815 to reset along the axial direction of the rotating rod 812.

[0027] The annular frame 811 is fixed to the inner wall of the vortex crusher 1, serving as the fixed support foundation for the entire airflow conditioning unit 8. The rotating rod 812 passes through the center of the annular frame 811 and rotates with it, serving as the common rotation axis for all rotating modules. The guide cone 815 is sleeved on the windward end of the rotating rod 812, with its outer arc surface facing the hot air input from the air supply pipe 5, used to disperse the concentrated hot air along the circumference. The spiral groove 819 is opened on the outer arc surface of the guide cone 815. When the hot air flows along the spiral groove 819, it pushes the guide cone 815 to rotate and disperses the hot air. The flow is transformed into a rotating airflow. The sliding fit between the guide belt 817 and the guide groove 818 allows the guide cone 815 to slide only along the axis of the rotating rod 812 and not rotate relative to it. The connecting ring 814 is rotatably installed in the annular groove 816 at the large diameter end of the guide cone 815, so that the thrust applied by the elastic element 813 can push the guide cone 815 to move axially without interfering with its own rotation. The elastic element 813 is connected between the connecting ring 814 and the annular frame 811, and always applies an elastic thrust toward the air supply pipe 5 to the guide cone 815.

[0028] Please see Figure 4 The elastic element 813 includes: The fixing sleeve 8131 is fixedly installed on the side wall at the center of the ring frame 811 to provide an installation anchor point for the elastic element 813; The slide rod 8132 is fixedly installed on one side of the connecting ring 814, and the slide rod 8132 is slidably connected to the fixed sleeve 8131 for sliding along the axial direction of the fixed sleeve 8131; Spring 8133 is fixedly installed between the end of slide rod 8132 and the inner wall of fixed sleeve 8131, and is used to push slide rod 8132 and connecting ring 814 to reset.

[0029] The fixed sleeve 8131 is fixed on the ring frame 811, providing a mounting base for the elastic element 813. One end of the slide rod 8132 is fixed to the connecting ring 814, and the other end is inserted into the fixed sleeve 8131 and slidably engaged with it, providing guidance for the axial movement of the connecting ring 814. The spring 8133 is installed inside the fixed sleeve 8131 and is always in a compressed state. Its elastic force is transmitted to the guide cone 815 through the slide rod 8132 and the connecting ring 814, pushing the guide cone 815 to move in the direction of the air supply pipe 5.

[0030] The guide cone 815 includes a large-diameter end and a small-diameter end. The small-diameter end of the guide cone 815 is located near the side of the air supply pipe 5, and the diameter of the large-diameter end is smaller than the inner diameter of the air supply pipe 5.

[0031] The small-diameter end of the guide cone 815 is positioned facing the air supply pipe 5, making it easy to extend into the inner port of the air supply pipe 5. The diameter of the large-diameter end of the guide cone 815 is smaller than the inner diameter of the air supply pipe 5, so that there is always an annular gap between the outer wall of the guide cone 815 and the inner wall of the air supply pipe 5 for the air supply to pass through. When the guide cone 815 moves axially, the cross-sectional area of ​​the annular gap changes accordingly, thereby realizing the adaptive adjustment of the intake throat area.

[0032] Please see Figure 5 The baffle temperature equalization module 82 includes: The sun gear 821 is fixedly installed on the outer wall of the rotating rod 812. The planet gear 822 is rotatably installed on the side wall of the ring frame 811. The rotating cylinder 823 is rotatably installed on the side wall of the ring frame 811. The planet carrier 824 is fixedly installed on the inner wall of the rotating cylinder 823 to cooperate with the rotation of the rotating rod 812 to form a planetary gear set. The flow equalization plate 825 is fixedly installed on the outer wall of the rotating drum 823. Several through holes 826 are opened on both sides of the flow equalization plate 825 to cooperate with the rotation of the planetary gear set to evenly distribute the airflow in the vortex crusher 1 in a circumferential direction. Hollow cavity 827, located inside flow equalization plate 825, serves as a buffer for airflow; The convex ring 828 is fixedly installed on the leeward side of the flow equalization plate 825. Several side holes 829 are distributed in a circular array on the arc-shaped inner surface of the convex ring 828 for radial dispersion of airflow in the vortex crusher 1.

[0033] The sun gear 821 rotates synchronously with the rotating rod 812. The planetary gear 822 is mounted on the ring frame 811 and meshes with the sun gear 821 and the planetary frame 824 respectively. The rotating cylinder 823 is driven by the planetary frame 824 and rotates at a speed lower than that of the rotating rod 812. The flow equalization plate 825 rotates with the rotating cylinder 823. The through holes 826 on its surface allow hot air to pass through. The hollow cavity 827 is opened inside the flow equalization plate 825 so that the hot air passing through the through holes 826 on the windward side is buffered in the cavity and then discharged from the through holes 826 on the leeward side. The convex ring 828 is set on the leeward side of the flow equalization plate 825. The side holes 829 on it spray part of the hot air radially so that the hot air after passing through the flow equalization plate 825 is evenly distributed on the cross section of the cylinder.

[0034] The axes of the side hole 829 and the through hole 826 are perpendicular to each other, and the interior of the convex ring 828 is hollow, with the internal cavity of the convex ring 828 communicating with the hollow cavity 827.

[0035] The side hole 829 is opened radially along the convex ring 828, and the through hole 826 is opened axially along the flow equalization plate 825. The airflow injection directions of the two are perpendicular to each other, so that the radially injected hot air and the axially passing hot air form a cross-mixing on the leeward side of the flow equalization plate 825. The internal cavity of the convex ring 828 and the hollow cavity 827 are interconnected, so that some of the hot air in the hollow cavity 827 can enter the interior of the convex ring 828 and be ejected from the side hole 829.

[0036] The through holes 826 on the windward and leeward sides of the flow equalization plate 825 are staggered.

[0037] The through holes 826 on the windward side and the through holes 826 on the leeward side of the flow equalization plate 825 are staggered in circumferential position, so that hot air cannot pass directly through the flow equalization plate 825 in a straight line, but must be turned inside the hollow cavity 827 before it can be discharged, thereby extending the buffer path of the airflow and making the pressure distribution more balanced.

[0038] Please see Figure 6 The repelling module 83 includes: The retaining ring 831 is fixedly installed on the outer wall of the end of the rotating rod 812 and is used to rotate synchronously with the rotation of the rotating rod 812. Three sets of curved plates 832 are fixedly installed on the outer wall of the fixing ring 831 in a circular array, and are used to disperse the tea leaves falling from above as the fixing ring 831 rotates. Several raised strips 833 are evenly distributed on the surface of the curved plate 832 to cooperate with the curved plate 832 to disperse the tea leaves in clumps.

[0039] The fixing ring 831 is fixed to the end of the rotating rod 812 and rotates synchronously with the rotating rod 812. The bending plate 832 rotates with the fixing ring 831. During the rotation, the tea leaves falling from the feed pipe 4 are periodically patted. The protrusion 833 is set on the surface of the bending plate 832. When the bending plate 832 pats the tea leaves, it increases the scraping and tearing effect on the tea clumps and disperses the sticky tea clumps into a loose state.

[0040] The surface of the bent plate 832 is inclined to the axis of the fixed ring 831, and the bent plate 832 is S-shaped.

[0041] The surface of the curved plate 832 is inclined to the axis of the fixed ring 831, so that when the curved plate 832 rotates, in addition to patting the tea leaves, it also generates a component force that pushes the tea leaves axially. The curved plate 832 extends in an S-shaped curve, so that the same curved plate 832 has different tangential inclination angles at different radial positions, thereby achieving multi-angle dispersion of falling tea leaves.

[0042] Working principle: High-temperature hot air is axially fed into the vortex crusher 1 through the air supply pipe 5. It first impacts the outer arc surface of the guide cone 815 of the floating vortex module 81. As the airflow flows along the spiral groove 819, it pushes the guide cone 815 to rotate, converting the concentrated hot air into a rotating airflow. When the hot air flow increases, the impact force on the windward surface of the guide cone 815 increases, overcoming the elastic force of the elastic element 813 and sliding along the rotating rod 812 away from the air supply pipe 5. The annular throat area between the inner wall of the air supply pipe 5 and the outer wall of the guide cone 815 increases accordingly, achieving adaptive expansion of the air intake channel. When the hot air flow decreases, the elastic element 813 pushes the guide cone 815 back to its original position, reducing the throat area, thereby maintaining the hot air flow. The hot air flows through the baffle plate 82 to drive the flow equalization plate 825 to rotate. The hot air passes through the through holes 826 distributed on both sides of the flow equalization plate 825 and is buffered and turned in the hollow cavity 827. Some of the hot air is sprayed radially through the side holes 829 on the convex ring 828, so that the hot air is evenly distributed on the cross section of the vortex crusher 1. At the same time, the rotating rod 812 drives the bending plate 832 of the dispersing module 83 to rotate. The tea leaves falling from the feed pipe 4 are beaten and dispersed into a loose state by the rotating bending plate 832 and the convex strip 833. The hot air after homogenization carries the dispersed tea leaves through the connecting cylinder 2 into the drying cylinder 3 for drying and color fixing. The exhaust gas and the processed tea leaves are finally discharged from the discharge pipe 6.
