Description

Technical Field

[0001] The present invention relates to the technical field of tea processing, and particularly to a crystallization device and a crystallization method for vine tea. Background Art

[0002] During the crystallization process of vine tea, the vine tea is placed in a suitable temperature environment. The flavonoid compounds in the vine tea will penetrate to the surface of the tea leaves and adhere to the tea leaves during the drying process, gradually crystallizing to form a uniform white frost. The white frost on the surface of the vine tea is an embodiment of its quality. Only vine tea rich in flavonoid compounds and with excellent production technology can form a uniform white frost.

[0003] In the prior art, for the crystallization of vine tea, the vine tea is usually wrapped with a cloth and then sent into a constant temperature chamber for static crystallization. However, the crystallization of vine tea has high temperature requirements. Once the central temperature of the vine tea exceeds 60 degrees Celsius, the vine tea needs to be taken out and broken up for cooling. Stacking the vine tea in the constant temperature chamber, the vine tea is likely to heat up, resulting in a large local temperature difference, which not only affects the crystallization efficiency of the vine tea but also reduces the crystallization quality of the vine tea. Summary of the Invention

[0004] An object of the present invention is to improve the temperature uniformity of vine tea during the crystallization process, thereby improving the crystallization effect of vine tea.

[0005] Another object of the present invention is to improve the automation degree of the crystallization device for vine tea and improve the crystallization efficiency of vine tea.

[0011] Further, a first support framework is arranged inside the first limiting ridge, and a second support framework is arranged inside the second limiting ridge; both the first support framework and the second support framework are made of metal materials.

[0012] Further, first toothed belts protruding outwards are respectively formed at both ends of the first conveyor belt, and second toothed belts protruding outwards are respectively formed at both ends of the second conveyor belt; at the opposite belt surfaces of the first conveyor belt and the second conveyor belt, the first toothed belt and the second toothed belt are meshed with each other.

[0013] Further, the crystallization device for bud tea further includes: a plurality of limiting disks respectively arranged at both ends of the plurality of cavities to close the plurality of cavities.

[0014] Further, a feed inlet is arranged at the top of the machine shell, and a discharge outlet is arranged at the bottom of the machine shell; the feed inlet and the discharge outlet are opposite to the belt surface of the first conveyor belt or the second conveyor belt.

[0016] The beneficial effects of the present invention are as follows:

[0017] For the crystallization device for bud tea of the present invention, by arranging the first conveyor belt and the second conveyor belt that are locally opposite to each other, the bud tea is squeezed into a flat thin layer by the first conveyor belt and the second conveyor belt, improving the overall temperature uniformity of the bud tea, and thus ensuring the crystallization effect of the bud tea. The opposite belt surfaces of the first conveyor belt and the second conveyor belt are set as an S shape with repeated bends, extending the conveying path of the bud tea and ensuring sufficient crystallization time for the bud tea.

[0039] The following will refer to Figures 1 to 11 to describe a crystallization device and a crystallization method for vine tea provided by the present invention.

[0040] Figure 1 is a schematic structural diagram of a crystallization device for vine tea according to an embodiment of the present invention. Figure 2 is a schematic structural diagram of a crystallization device for vine tea according to an embodiment of the present invention; wherein, in order to better show the assembly structure of the first conveyor belt 300 and the second conveyor belt 400, the structures of the machine shell 100 and the temperature control device 600, etc. are hidden. Figure 3 is Figure 2 a schematic enlarged view of area A in

[0041] As Figures 1 - 3 shown, this embodiment first provides a crystallization device for vine tea. The crystallization device for vine tea generally may include: a machine shell 100, a plurality of drive rollers 200, a first conveyor belt 300, a second conveyor belt 400, and a temperature control device 600.

[0042] A plurality of driving rollers 200 are rotatably arranged on the casing 100. The first conveyor belt 300 and the second conveyor belt 400 are arranged inside the casing 100 and sleeved on the plurality of driving rollers 200. The belt surface parts of the first conveyor belt 300 and the second conveyor belt 400 face each other and are used for clamping and conveying the bud tea. The opposite belt surfaces of the first conveyor belt 300 and the second conveyor belt 400 are in a repeatedly bent S shape in the vertical direction; and at each bending point, the distance between the first conveyor belt 300 and the second conveyor belt 400 increases to form a cavity 500. The temperature control device 600 is arranged at the bottom of the casing 100 and is used for maintaining the air inside the casing 100 within a preset temperature range.

[0043] In the solution of this embodiment, by arranging the first conveyor belt 300 and the second conveyor belt 400 with opposite local belt surfaces, the bud tea is clamped by the first conveyor belt 300 and the second conveyor belt 400 and extruded into a flat thin layer, thereby improving the overall temperature uniformity of the bud tea and further ensuring the crystallization separation effect of the bud tea. The opposite belt surfaces of the first conveyor belt 300 and the second conveyor belt 400 are arranged in a repeatedly bent S shape, which prolongs the conveying path of the bud tea and ensures that the bud tea has sufficient crystallization separation time during the whole transportation process. A cavity 500 is arranged at each bending point, so that when the bud tea is transported to the cavity 500, it slides and tumbles under the action of gravity, and thus is dispersed, further improving the temperature uniformity of the bud tea and enhancing the crystallization separation effect of the bud tea. By arranging the temperature control device 600, the air temperature inside the casing 100 is maintained within a preset temperature range, so that the bud tea is within a temperature range suitable for crystallization separation, thereby improving the crystallization separation effect and efficiency of the bud tea.

[0044] Furthermore, in the solution of this embodiment, by arranging the first conveyor belt 300 and the second conveyor belt 400, while ensuring the crystallization separation effect of the bud tea, the automatic transportation of the bud tea is realized. The automated process of the crystallization separation technology of the bud tea greatly improves the production efficiency of the bud tea and reduces the labor cost.

[0045] In some preferred embodiments, the temperature control device 600 is configured to maintain the air temperature inside the casing 100 within a temperature range of 50°C to 60°C.

[0046] In some preferred embodiments, the casing 100 can be configured as a heat-insulating casing to improve the overall heat-insulating performance of the crystallization separation equipment for the bud tea, enhance the temperature stability of the air inside the casing 100, and thus enhance the crystallization separation effect.

[0047] In some preferred embodiments, the temperature control device 600 may include a temperature sensor and a heating device. The heating device may be configured as an air inlet pipe for delivering hot air within a preset temperature range into the casing 100. The temperature of the hot air may be preset between 50°C and 60°C. The heating device is arranged at the bottom of the casing 100. Utilizing the characteristic that hot air naturally rises, the temperature uniformity of the air within the casing 100 is improved, thereby enhancing the crystallization effect of the moyeam tea.

[0048] In some preferred embodiments, at each bend where the cavity 500 is formed, the first conveyor belt 300 and the second conveyor belt 400 may share a driving roller 200. Moreover, when the first conveyor belt 300 and the second conveyor belt 400 at the bend are first installed on the same driving roller 200, by leaving a longer length for the belt surface on the outer side of the driving roller 200, the distance between the first conveyor belt 300 and the second conveyor belt 400 is increased to form the cavity 500.

[0049] The crystallization device for moyeam tea generally may also be provided with a power device (e.g., a motor). The power device is connected to the driving roller 200 to provide power for the rotation of the driving roller 200 and adjust the rotation speed of the driving roller 200. In some embodiments, the power device may provide power for multiple driving rollers 200 simultaneously to ensure that the rotation speeds of the multiple driving rollers 200 are consistent.

[0050] The distance between the horizontally arranged belt surfaces of the first conveyor belt 300 and the second conveyor belt 400 facing each other can be set according to actual needs. In some embodiments, the horizontally arranged belt surfaces of the first conveyor belt 300 and the second conveyor belt 400 facing each other may be closely adjacent to minimize the layer thickness of the moyeam tea to the greatest extent. In other embodiments, a certain gap may be formed between the first conveyor belt 300 and the second conveyor belt 400 to ensure the transportation efficiency of the moyeam tea.

[0051] As Figure 2 、 5 shown, the crystallization device for moyeam tea generally may also include a plurality of stirring rods 510.

[0052] The plurality of stirring rods 510 are rotatably arranged on the casing 100 and are located within the plurality of cavities 500. Among them, the plurality of stirring rods 510 are arranged in one-to-one correspondence with the plurality of cavities 500.

[0053] The solution of this embodiment, by arranging the rotating stirring rods 510 at the cavity 500 to stir and disperse the moyeam tea, further improves the overall temperature uniformity of the moyeam tea, thereby avoiding the situation where the moyeam tea accumulates and agglomerates, resulting in too large a local temperature difference and affecting the crystallization effect.

[0054] In some preferred embodiments, at least one stirring blade may be provided on the stirring rod 510 to enhance the stirring effect, thereby further reducing the temperature difference of the moyeam tea and improving the crystallization quality of the moyeam tea.

[0055] The rotation speed of the stirring rod 510 is inversely proportional to the rotation speed of the transmission roller 200.

[0056] The crystallization time of the moyeam tea is related to the season, and different crystallization time requirements are needed for the moyeam tea in different seasons. In some preferred embodiments, the crystallization time of the moyeam tea in summer is 2 - 2.5 hours, and the crystallization time of the moyeam tea in spring and autumn is 3 - 4 hours. When ensuring the production efficiency of the moyeam tea, the slower the rotation speed of the transmission roller 200 (that is, the longer the crystallization time of the moyeam tea), the more moyeam tea is clamped between the first conveyor belt 300 and the second conveyor belt 400.

[0057] In the solution of this embodiment, the rotation speed of the stirring rod 510 is set to be inversely proportional to the rotation speed of the transmission roller 200, so that the stirring effect of the stirring rod 510 is adapted to the quantity of the moyeam tea, thereby ensuring the temperature uniformity of the moyeam tea and improving the crystallization effect of the moyeam tea. When the rotation speed of the transmission roller 200 is relatively fast (that is, the quantity of the moyeam tea clamped between the first conveyor belt 300 and the second conveyor belt 400 is small), the stirring rod 510 completes the dispersion of the moyeam tea at a slower rotation speed, thereby reducing the risk of damage to the leaves of the moyeam tea while ensuring the temperature uniformity of the moyeam tea. When the rotation speed of the transmission roller 200 is slow (that is, the quantity of the moyeam tea clamped between the first conveyor belt 300 and the second conveyor belt 400 is large), the rotation speed of the stirring rod 510 increases to improve the stirring effect, thereby ensuring the temperature uniformity of the moyeam tea and further ensuring the crystallization effect of the moyeam tea.

[0058] The first conveyor belt 300 and the second conveyor belt 400 are made of a non - elastic material with good air permeability.

[0059] In the solution of this embodiment, the first conveyor belt 300 and the second conveyor belt 400 are made of a material with good air permeability, which improves the contact effect between the moyeam tea and the air in the machine housing 100, ensures that the leaves of the moyeam tea can be maintained within a suitable temperature range for crystallization, and thus improves the crystallization effect and crystallization efficiency of the moyeam tea.

[0060] The horizontally - arranged belt surfaces of the first conveyor belt 300 and the second conveyor belt 400 that face each other will form an arched shape convex in the middle under the extrusion of the moyeam tea they clamp. In the solution of this embodiment, the first conveyor belt 300 and the second conveyor belt 400 are set as non - elastic materials, so that when the horizontally - arranged belt surfaces of the first conveyor belt 300 and the second conveyor belt 400 form an arch, the cavity 500 formed between the first conveyor belt 300 and the second conveyor belt 400 can also become a constricted shape with smaller ends and larger middle, thereby reducing the risk of the moyeam tea falling off from both ends of the cavity 500.

[0061] In some preferred embodiments, the first conveyor belt 300 and / or the second conveyor belt 400 may be configured with inelastic fabrics, such as cotton linen, or polyester fabric, etc.

[0062] At both ends of the first conveyor belt 300, first limiting ridges 310 protruding inward are respectively formed. At both ends of the second conveyor belt 400, second limiting ridges 410 protruding inward are respectively formed. At both ends of each driving roller 200, limiting grooves 210 are respectively formed. When the first conveyor belt 300 or the second conveyor belt 400 abuts against the driving roller 200, the first limiting ridge 310 or the second limiting ridge 410 is snapped into the limiting groove 210.

[0063] In the solution of this embodiment, by providing the first limiting ridge 310, the second limiting ridge 410 and the limiting groove 210, when the first conveyor belt 300 or the second conveyor belt 400 abuts against the driving roller 200, the first limiting ridge 310 or the second limiting ridge 410 is snapped into the limiting groove 210, thereby restricting the displacement of the first conveyor belt 300 or the second conveyor belt 400 in the width direction, improving the structural stability of the first conveyor belt 300 and the second conveyor belt 400, and ensuring the smooth transportation of the moyeam tea.

[0064] As Figure 8 shown, when the first conveyor belt 300 is sleeved on the driving roller 200, the first limiting ridge 310 is embedded in the limiting groove 210, and the belt surface of the first conveyor belt 300 remains flat. The belt surface of the second conveyor belt 400 on its outer side forms an arched shape with both ends contracting inward and the middle bulging outward under the extrusion of the clamped moyeam tea. When the second conveyor belt 400 is sleeved on the driving roller 200, the second limiting ridge 410 is embedded in the limiting groove 210, and the belt surface of the second conveyor belt 400 remains flat. The belt surface of the first conveyor belt 300 on its outer side forms an arched shape with both ends contracting inward and the middle bulging outward under the extrusion of the clamped moyeam tea.

[0065] In some embodiments, the limiting ridge may be made of rubber material to improve its corrosion resistance, wear resistance and anti-aging performance, etc.

[0066] A first support framework 311 is arranged inside the first limiting ridge 310, and a second support framework 411 is arranged inside the second limiting ridge 410. Both the first support framework 311 and the second support framework 411 are made of metal materials.

[0067] The solution of this embodiment utilizes the rigid characteristics of the first support frame 311 and the second support frame 411, enabling the first conveyor belt 300 or the second conveyor belt 400 to resist its own weight and maintain a stable arc shape at the cavity 500 without the direct support of the driving roller 200. This ensures sufficient and stable space within the cavity 500, guarantees the normal operation of the stirring rod 510, and ensures the tumbling effect of the moyeam tea.

[0068] In some preferred embodiments, the first support frame 311 and / or the second support frame 411 can be configured as steel belts.

[0069] At both ends of the first conveyor belt 300, there are also formed first toothed belts 320 protruding outward, and at both ends of the second conveyor belt 400, there are also formed second toothed belts 420 protruding outward. At the opposing belt surfaces of the first conveyor belt 300 and the second conveyor belt 400, the first toothed belt 320 and the second toothed belt 420 are meshed.

[0070] The solution of this embodiment, by respectively providing the first toothed belt 320 and the second toothed belt 420 on the first conveyor belt 300 and the second conveyor belt 400, creates a certain gap between the first conveyor belt 300 and the second conveyor belt 400, thus ensuring the conveying efficiency of the moyeam tea. By utilizing the meshing of the first toothed belt 320 and the second toothed belt 420, the transmission speeds of the first conveyor belt 300 and the second conveyor belt 400 are kept consistent, avoiding relative movement between the horizontally opposing belt surfaces of the first conveyor belt 300 and the second conveyor belt 400, thereby reducing the risk of damage to the leaves of the moyeam tea. At the same time, the meshing arrangement of the first toothed belt 320 and the second toothed belt 420 improves the structural stability of the cavity 500.

[0071] In some preferred embodiments, the bandwidths of the first toothed belt 320 and the second toothed belt 420 can be set according to the transportation volume of the moyeam tea, so as to ensure that after the first conveyor belt 300 or the second conveyor belt 400 contracts and moves inward under the extrusion of the moyeam tea, the first toothed belt 320 or the second toothed belt 420 can still remain in the meshed state, thereby ensuring the synchronous transmission of the first conveyor belt 300 and the second conveyor belt 400, and at the same time reducing the risk of the moyeam tea leaking from the sides of the first conveyor belt 300 and the second conveyor belt 400.

[0072] The crystallization equipment for moyeam tea generally may also include a plurality of limiting discs 520.

[0073] The plurality of limiting discs 520 are respectively arranged at both ends of the plurality of cavities 500 to enclose the plurality of cavities 500.

[0074] The solution of this embodiment, by providing the limiting discs 520 to enclose the cavity 500, further reduces the risk of the moyeam tea slipping from both ends of the cavity 500.

[0075] A feed inlet 110 is provided at the top of the casing 100, and a discharge outlet 120 is provided at the bottom of the casing 100. The feed inlet 110 and the discharge outlet 120 face the belt surface of the first conveyor belt 300 or the second conveyor belt 400.

[0076] In the solution of this embodiment, the feed inlet 110 is arranged at the top of the casing 100, and the discharge outlet 120 is arranged at the bottom of the casing 100, so that the moyeam tea moves horizontally by means of the first conveyor belt 300 and the second conveyor belt 400, and moves vertically by its own weight. It not only has a reasonable and stable structure, but also improves the convenience of feeding and collecting the moyeam tea.

[0077] The size of the feed inlet 110 can be set according to actual needs. In some embodiments, the size of the feed inlet 110 can be set to be relatively large, and the part of the top of the casing 100 facing the belt surface of the first conveyor belt 300 can be all set as the feed inlet 110 to improve the feeding efficiency of the moyeam tea.

[0078] In some embodiments, a fence 111 can also be provided on the feed inlet 110, so as to avoid accidental injury to the operators and improve the safety performance of the crystallization equipment for moyeam tea. At the same time, other sundries can be prevented from accidentally falling into the feed inlet 110, ensuring the normal operation of the crystallization equipment for moyeam tea and improving its aesthetics.

[0079] In some embodiments, the discharge outlet 120 can be set to be relatively small for the convenience of collecting the moyeam tea.

[0080] In some embodiments, support legs 130 can also be provided at the bottom of the casing 100 to support the casing 100 and keep the casing 100 away from the ground, so as to facilitate the collection of the moyeam tea from the discharge outlet 120.

[0081] In the solution of this embodiment, by arranging the feed inlet 110 at the top of the casing 100 and the discharge outlet 120 at the bottom of the casing 100, and using the first conveyor belt 300 and the second conveyor belt 400 to transport and crystallize the moyeam tea, its automated process not only improves the crystallization quality of the moyeam tea, but also improves the production efficiency of the moyeam tea and reduces the labor cost.

[0082] The specific working process of the crystallization equipment for moyeam tea provided by the present invention will be described in combination with the above embodiments:

[0083] The temperature control device 600 is activated to maintain the air temperature inside the casing 100 within a preset temperature range. The moyeam tea is fed into the casing 100 through the feed inlet 110 and lands on the belt surface of the first conveyor belt 300. The power device is activated to drive the transmission roller 200 to rotate, and the first conveyor belt 300 and the second conveyor belt 400 start to rotate. The moyeam tea moves under the drive of the first conveyor belt 300 and begins to contact the opposing second conveyor belt 400. Under the extrusion of the first conveyor belt 300 and the second conveyor belt 400, the moyeam tea forms a flattened thin layer. Thereafter, the moyeam tea moves while being clamped by the first conveyor belt 300 and the second conveyor belt 400. Among them, when the moyeam tea moves to the cavity 500 at the bending point, it freely falls under the action of gravity and is dispersed under the agitation of the stirring rod 510 to reduce the temperature difference of the moyeam tea and improve the crystallization effect. The moyeam tea moves slowly inside the casing 100 and gradually completes crystallization, and finally moves to the discharge outlet 120 under the transportation of the first conveyor belt 300 and the second conveyor belt 400 and is discharged from the discharge outlet 120.

[0084] Figure 11 is a schematic flow chart of a crystallization method for moyeam tea according to an embodiment of the present invention.

[0085] As Figure 11 shown, this embodiment also provides a crystallization method for moyeam tea, and the crystallization equipment of any one of the above is used for the crystallization of moyeam tea. The crystallization method for moyeam tea generally may include:

[0086] Step S1102: Activate the temperature control device 600 to maintain the air inside the casing 100 within a preset temperature range.

[0087] Step S1104: Feed the moyeam tea to be crystallized through the feed inlet 110 at the top of the casing 100.
