Description

Technical Field

[0001] The utility model patent relates to tea processing equipment, in particular to a high-quality tea dryer. Background Art

[0002] Drying and fragrance enhancement of tea are important steps in tea processing. Its function is to bake out the moisture and aroma of tea through high temperature, dry the tea, completely eliminate the grassy smell in the tea, and improve the taste and aroma of the tea. The drying process of high-quality tea is often carried out by using a drying equipment with a drying net.

[0003] The name is "A Tea Dryer" (document number: CN208875298U, hereinafter referred to as Document 1). In this Document 1, it includes a chassis 1, a vibration motor 2 and a tray rack 3. The vibration motor 2 is installed at the bottom of the chassis 1, and one end of the vibration motor 2 extends into the chassis 1. The tray rack 3 is placed in the chassis 2, the vibration motor 2 is connected to the tray member 3, and a tray 4 is placed on the tray rack 3. The sieve-shaped trays 4 are arranged up and down in the chassis 1, and the tea is placed on the trays 4 for heating.

[0004] The name is "A Tea Dryer" (document number: CN204180819U, hereinafter referred to as Document 2). In this Document 2, a plurality of trays 11 for holding tea are arranged up and down on a rotating shaft 3, and a number of through holes 14 and filter meshes 15 are provided on the trays 11. When this high-quality tea dryer enhances the fragrance of the tea, the tea is placed on a plurality of trays 11 for heating, which can increase the heating area of the tea.

[0005] In the above technical solutions, the tea is stacked up and down. The moisture volatilized from the tea on the bottom tray will flow to the upper tray. When taking out the tea after drying, the tea on the upper tray is wetter than that on the lower tray. Therefore, when the tea is finally taken out, the drying degrees of the tea on each layer are inconsistent, affecting the final tea processing quality. Summary of the Invention

[0006] The utility model provides a high-quality tea dryer to ensure the consistency of the drying degree of the tea.

[0007] To achieve the above purpose, the technical solution adopted is: a high-quality tea dryer, including a box body. A drying chamber is provided inside the box body. The drying nets for holding tea are placed in the drying chamber in a stacked manner from top to bottom. There is a guiding outlet for taking out the drying net on one side of the bottom of the drying chamber, and a guiding inlet for placing the drying net on one side of the top of the drying chamber. After the tea is dried from top to bottom, it is exported horizontally at the guiding outlet.

[0008] Compared with the prior art, the technical effect of the utility model is as follows: The drying net for holding tea leaves is placed in the drying chamber in a stacked manner from top to bottom. After the tea leaves are dried, the drying net is translated and exported from top to bottom to the outlet at the bottom of the drying chamber. The tea leaves at the bottom are not affected by the moisture of the upper layer, so that the drying degree of the tea leaves removed successively is basically the same, ensuring the quality of the final tea product.

[0024] The following will further elaborate on the present utility model in conjunction with the attached Figures 1 - 15 drawings and related content:

[0025] A famous-quality tea dryer includes a box body 10. A drying chamber 11 is arranged inside the box body 10. The drying nets 60 for holding tea leaves are placed in the drying chamber 11 in a stacked manner from top to bottom. One side at the bottom of the drying chamber 11 has a guiding outlet 13 for taking out the drying net 60, and one side at the top of the drying chamber 11 has a guiding inlet for placing the drying net 60. After being dried from top to bottom, the drying net 60 is translated and exported from the guiding outlet 13.

[0026] In the above solution, when drying the tea leaves, the drying nets for holding the tea leaves are placed in the drying chamber in a stacked manner from top to bottom, and the drying treatment of the tea leaves is realized under the heating of the heat source. After the tea leaves are dried, the drying net 60 is translated and exported from the guiding outlet 13 at the bottom of the drying chamber 11 from top to bottom. Since the moisture volatilized from the tea leaves on the upper drying net 60 has an upward flow trend, the tea leaves on the bottom drying net 60 are not affected by the upper moisture, so that the dryness of the tea leaves on the drying nets 60 successively removed from the bottom guiding outlet 13 can be basically the same, ensuring the quality of the tea products.

[0027] Further, in order to facilitate the removal of the bottom drying net 60 after drying from the guiding outlet 13, movable rods or plates 21 are arranged at the bottom of the drying chamber 11. The movable rods or plates 21 are respectively at the supporting position for supporting the second-to-bottom drying net 60 inside the bottom of the drying chamber 11 or at the avoiding position separated from the second-to-bottom drying net 60 inside the bottom of the drying chamber 11. In this solution, by using the movable rods or plates 21 to support the second-to-bottom drying net 60 inside the bottom of the drying chamber 11, the lowermost drying net 60 can be in a free state without the pressure of the upper drying net 60, which is convenient for being drawn out from the drying chamber 11 at the guiding outlet 13. Subsequently, control the movable rods or plates 21 to be at the avoiding position separated from the second-to-bottom drying net 60 inside the bottom of the drying chamber 11, and the stacked drying nets 60 inside the drying chamber 11 can fall naturally. Repeating this process, after the drying of the tea leaves placed in the drying nets 60 inside the drying chamber 11 is completed, they can be successively removed from the bottom guiding outlet 13, thereby completing the drying treatment of the tea leaves.

[0028] In order to ensure that the drying net 60 will not fall after being placed at the bottom inside the drying chamber 11, strip-shaped supporting plates 14 with flat surfaces are arranged on the left and right sides at the bottom of the drying chamber 11. The front end of the supporting plate 14 is connected or abuts and joins with the bottom edge of the guiding outlet 13, and the rear end of the supporting plate 14 extends towards the rear wall of the drying chamber 11. The supporting plate 14 can play a role in supporting the drying net 60, preventing the drying net 60 placed at the bottom inside the drying chamber 11 from falling downward, and facilitating the smooth export of the drying net 60 from the guiding outlet 13.

[0029] As a preferred solution, there are two power rotating shafts 22 arranged parallel to each other, at the same height and horizontally in the drying chamber 11. The power rotating shafts 22 are either parallel to the front and rear box walls of the box body 10 or parallel to the left and right box walls. The movable rods or plates 21 with coplanar plate surfaces are fixedly arranged on the power rotating shafts 22 at intervals in a cantilevered manner; when the movable rods or plates 21 rotate with the power rotating shafts 22, the movable rods or plates 21 are in a position where they avoid the peripheral wall surface of the frame of the drying mesh 60 when stacked with the drying mesh 60 in the drying chamber 11, or are inserted into the bottom edge part of the frame of the second last drying mesh 60 at the bottom of the drying chamber 11 and support the second last drying mesh 60 and the drying meshes 60 above it to the support position.

[0030] By controlling the rotation of the power rotating shaft 22, the movable rod or plate 21 can swing upwards. The cantilever end of the movable rod or plate 21 can support the second last drying mesh 60 in the drying chamber 11, so that the lowest drying mesh 60 in the drying chamber 11 can be separated from the drying meshes 60 above it. The lowest drying mesh 60 is in a free state without being pressed by the drying meshes 60 above it, which is convenient for moving out from the export 13. Subsequently, the movable rod or plate 21 can be controlled to swing downwards to a position where it avoids the drying mesh 60, and the movable rod or plate 21 will not interfere with the drying mesh 60. Then, the subsequent drying meshes 60 in the drying chamber 11 can fall to a position where they are in the same position as the export 13, which is convenient for moving out from the export 13. As shown in combination with Figure 10 、 11 shown, Figure 10 Figure 9 shows the state where the movable plate 21 and the drying mesh 60 are in a mutually avoiding position, Figure 11 Figure 10 shows the state where the movable plate 21 is in the state of supporting the drying mesh 60, that is, a height difference h of 1 - 5 mm is formed between the lowest drying mesh 60 and the second last drying mesh 60. The second last drying mesh 60 will not be pressed on the lowest drying mesh 60, that is, the last drying mesh 60, and the last drying mesh 60 can be conveniently moved and taken out.

[0031] As a preferred solution, the power rotating shafts 22 are respectively arranged adjacent to and parallel to the front and rear box walls of the box body 10. The front power rotating shaft 22 is located inside the upper edge of the export 13. When the movable plate 21 rotates with the power rotating shaft 22 to the support position for supporting the second last drying mesh 60, the movable plate 21 avoids the export path of the last drying mesh 60 below it. In this solution, the power rotating shafts 22 are respectively arranged at the front and rear box walls of the drying chamber 11, and the drying mesh 60 is located in the area between the two power rotating shafts 22. The movable plate 21 supports or avoids the front and rear frame edges of the drying mesh 60. The example shown in the drawings is that the power rotating shaft 22 is provided with a square movable plate 21, and the plate edge on the long side of the movable plate 21 is fixed on the power rotating shaft 22. For the sake of brevity below, the movable rods or plates 21 are all described in the name of the movable plate 21.

[0032] Combined with Figure 6 、 7, as shown in Figure 8, the shaft end of the power rotating shaft 22 is connected to one end of the first crank 26. The other end of the first crank 26 is hinged to one end of the first connecting rod 25. The other end of the first connecting rod 25 is hinged to the upper end of the vertically arranged upright rod 24. The two ends of the horizontal longitudinal rod 23 with a horizontal rod length are respectively provided with upright rods 24 and are arranged corresponding to the shaft ends of the two power rotating shafts 22. The longitudinal rod 23 is driven by a lifting mechanism to move up and down. By driving the longitudinal rod 23 to move up and down by the lifting mechanism, the upright rod 24 thereon can be synchronously moved up and down. Further, through the connection of the first connecting rod 25, the upright rod 24 can drive the first crank 26 to swing, so that the power rotating shaft 22 connected thereto rotates around its own axis. The movable plate 21 arranged on the power rotating shaft 22 can then swing to support or avoid the second last drying screen 60 in the drying chamber 11. It should be noted that the two power rotating shafts 22 are respectively controlled by two symmetrically arranged first cranks 26 to rotate synchronously and reversely, so that the movable plates 21 on the front and rear sides of the drying screen 60 support the drying screen 60 synchronously, and the drying screen 60 can be stably supported.

[0033] To better show the state changes of the first connecting rod 25 and the first crank 26 during movement, as Figure 9 shown, the dotted line in the figure is the position of the longitudinal rod 23 when it rises to the high position and the corresponding positions of the corresponding components.

[0034] Further, there is a lifting rod 41 extending downward from the middle of the longitudinal rod 23. The driving rotating shaft 30 is connected to one end of the second crank 42. The other end of the second crank 42 is hinged to one end of the second connecting rod 43. The other end of the second connecting rod 43 is hinged to the middle upper part of the lifting rod 41. The limit wheel set 50 limits the up and down translation path of the lifting rod 41. In this solution, by driving the driving shaft 30 to rotate, the second crank 42 can swing, so that the second connecting rod 43 pushes the lifting rod 41 and the longitudinal rod 23 thereon to move up and down. The limit wheel set 50 can limit the movement of the lifting rod 41 to enable it to stably move up and down in the vertical direction. In this solution, as Figure 7 shown, the limit wheel set 50 can be composed of guide wheels clamped on both sides of the rod body of the lifting rod 41. The guide wheels are provided with limit grooves, and the rod body of the lifting rod 41 is located in the limit grooves to limit the horizontal displacement of the lifting rod 41.

[0035] Since the hinge shaft cores at both ends of the second connecting rod 43 are parallel to the axis of the driving shaft 30, the lifting rod 41 can only move up and down and has no possibility of rotating around its own rod core. In this way, it is ensured that the longitudinal rod 23 only makes translational movement in the up and down direction. In addition, the lifting rod 41 can also be selected as an I-beam or a square rod, and by cooperating with the limit wheel set 50, the degree of freedom of the lifting rod 41 rotating around its own rod core is limited.

[0036] The following gives two implementation manners for the movable plate 21 to support the drying screen 60:

[0037] First, combine Figure 10 、 11 As shown in Figures 1 and 2, a recess 61 is provided on the bottom surface of the lower frame rod on the opposite side of the drying net 60. The recess 61 extends to the outer side of the lower frame rod of the drying net 60. When the movable plate 21 swings, it is respectively located in a supporting position of the recess 61 supporting the second-to-last drying net 60 at the bottom of the drying chamber 11 or in a evasive position separated from the second-to-last drying net 60 at the bottom of the drying chamber 11. In this embodiment, when the movable plate 21 swings upward to a high position, its overhanging end can swing into the recess 61 of the second-to-last drying net 60 at the bottom of the drying chamber 11. By abutting the inner top of the recess 61, the second-to-last drying net 60 and the drying nets 60 above it can be supported, thereby facilitating the removal of the lowest drying net 60 from the guide outlet 13. When the movable plate 21 falls back to the low position, the overhanging end of the movable plate 21 moves out of the recess 61 on the drying net 60 and avoids the frame edge of the drying net 60. The second to last drying net 60 can naturally fall to the lowest position and wait for subsequent removal. Figure 12 The middle concave portion 61 is arranged on the front and rear opposite sides of the lower frame rod of the drying net 60, and the concave portions 61 can be arranged equally on the left and right sides.

[0038] In this solution, after the bottom drying net 60 is removed, as the movable plate 21 swings downward, the penultimate drying net 60 will slide relative to the plate body of the movable plate 21 and gradually move downward. When the overhanging end of the movable plate 21 is at a critical position about to disengage from the recess 61 of the penultimate drying net 60, the distance between the lower frame surface of the penultimate drying net 60 in the drying chamber 11 and the inner bottom of the drying chamber 11 is approximately half the height of a single drying net 60. At this time, the movable plate 21 is controlled to disengage from the recess 61. Since the bottom drying net 60 is relatively close to the inner bottom of the drying chamber 11, the drying net 60 will not collide violently with the inner bottom of the drying chamber 11 when it falls, thus ensuring the integrity of the drying net 60 and the equipment.

[0039] Second, combine Figure 13 、 14As shown in Figures 1 and 2, a downwardly facing inclined surface 62 is provided on the outer side surface of the lower frame rod on the opposite side of the drying mesh 60. The end of the movable plate 21 close to the drying mesh 60 is a wedge-shaped end. When the movable plate 21 translates, the wedge-shaped end is respectively in a supporting position where it abuts against the inclined surface 62 of the second-to-last drying mesh 60 at the bottom of the drying chamber 11 and supports the second-to-last drying mesh 60 at the bottom of the drying chamber 11, or in an avoidance position where it is separated from the second-to-last drying mesh 60 at the bottom of the drying chamber 11. In this embodiment, when the wedge-shaped end of the movable plate 21 translates to abut against the inclined surface 62 on the second-to-last drying mesh 60 at the bottom of the drying chamber 11, the compression between the wedge-shaped end and the inclined surface 62 forces the second-to-last drying mesh 60 and the drying mesh 60 above it to move upward relative to the lowest drying mesh 60, thereby achieving a supporting action for the drying mesh 60. When the wedge-shaped end of the movable plate 21 moves in the opposite direction to avoid the inclined surface 62 or the frame rod of the drying net 60, the second to last drying net 60 can naturally fall to the lowest position and wait for subsequent removal. Figure 13 The middle inclined surface 62 is arranged on the front and rear opposite sides of the lower frame rod of the drying net 60, and the inclined surfaces 62 can be arranged equally on the left and right sides.

[0040] In this embodiment, after the bottom drying net 60 is removed, the wedge-shaped end slides relative to the inclined surface 62 on the penultimate drying net 60 as the movable plate 21 translates in the opposite direction, causing the drying net 60 to gradually move downward. When the tip of the wedge-shaped end of the movable plate 21 is at a critical position about to disengage from the inclined surface 62 of the penultimate drying net 60, the distance between the lower frame surface of the penultimate drying net 60 in the drying chamber 11 and the inner bottom of the drying chamber 11 is also approximately half the height of a single drying net 60. At this time, the wedge-shaped end is controlled to disengage from the inclined surface 62. Since the bottom drying net 60 is relatively close to the inner bottom of the drying chamber 11, the drying net 60 will not violently collide with the inner bottom of the drying chamber 11 when it falls, thus ensuring the integrity of the drying net 60 and the equipment.
