Description

Technical Field

[0001] This utility model relates to the field of tea, and more specifically, to a tea forming production line. Background Technology

[0002] Tea processing is a process that uses physical and chemical methods to alter the shape and internal substances of tea leaves, giving them a specific flavor and appearance. In the entire process of processing granular oolong tea, the shaping process is the key step that determines the appearance of the tea leaves, and it occurs before the drying process. During the shaping process, the tea leaves undergo multiple cycles of "rolling and breaking up clumps," and between these cycles, the tea leaves are subjected to a "fire" process. This fire process causes the tea leaves to lose moisture appropriately and changes their plasticity, thus facilitating the gradual tightening of the leaves.

[0003] An existing automated tea production line includes a forming module for performing the forming process. Specifically, after the tea leaves undergo one or more "rolling-untangling" processes in the forming module, they need to be manually or transported to a separate firing device for firing. The fired tea leaves are then transported back to the forming module in the same manner to continue the "rolling-untangling" process. However, the time spent transporting the tea leaves lengthens the overall production cycle, and the transport action reduces the continuity of the production line, thus affecting the overall efficiency of the forming process.

[0010] In some embodiments of this application, the heat treatment module includes a heat treatment machine, a first elevator, and a second elevator.

[0029] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0030] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0031] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0032] Please see Figure 1 and Figure 2 The tea forming production line provided in one embodiment of this utility model mainly includes a forming module 1 and a heat treatment module 2. The forming module 1 includes a first forming module 11 and a second forming module 12 arranged sequentially. The first forming module 11 is used to receive tea leaves input from the outside, and the second forming module 12 is used to output the tea leaves. Both the first forming module 11 and the second forming module 12 include forming units for performing forming operations on the tea leaves. The heat treatment module 2 is used to heat the tea leaves and is provided with at least one heat treatment module. At least one heat-treated module 2 is disposed within the first molding module 11, the first molding module 11 includes at least two molding units connected in sequence, and at least one pair of adjacent molding units in the first molding module 11 are connected by the heat-treated module 2; and / or, at least one heat-treated module 2 is disposed within the second molding module 12, the second molding module 12 includes at least two molding units connected in sequence, and at least one pair of adjacent molding units in the second molding module 12 are connected by the heat-treated module 2; and / or, at least one heat-treated module 2 is disposed between the first molding module 11 and the second molding module 12, and is used to connect two adjacent molding units between the first molding module 11 and the second molding module 12.

[0033] In the tea forming production line of this embodiment, externally input tea leaves enter the first forming module 11 of the forming module. After being processed by one or more forming machines in the first forming module 11, the tea leaves enter the second forming module 12 and are similarly processed by one or more forming machines in the second forming module 12 before being output. During this process, since the heat treatment module 2 is integrated into the forming module 1 and can connect two adjacent forming machines, the tea leaves can undergo a heat treatment process between two complete forming operations. This gives the tea forming production line a continuous "forming-heat treatment-forming" process, saving the steps of manually or using transfer equipment to transfer the tea leaves from the forming module 1 to the heat treatment module 2 and back from the heat treatment module 2 to the forming module 1, thus improving the continuity of the production line and eliminating the time spent transferring tea leaves, shortening the overall production cycle and improving the overall efficiency of the forming process.

[0034] It should be noted that the arrangement of the heat-treated modules 2 can be as follows: only within the first molding module 11, only within the second molding module 12, or only between the first molding module 11 and the second molding module 12. Alternatively, they can be arranged separately within the first molding module 11 and the second molding module 12, separately within the first molding module 11 and between the first molding module 11 and the second molding module 12, or separately between the first molding module 11 and the second molding module 12 and within the second molding module 12. They can also be arranged separately within the first molding module 11, the second molding module 12, and between the first molding module 11 and the second molding module 12. The specific number and arrangement of the heat-treated modules 2 can be selected according to actual production needs.

[0035] It should be further explained that the arrangement of the heat-treated module 2 within the first forming module 11 can be between one or more pairs of adjacent forming units. Furthermore, the heat-treated module 2 arranged between each pair of adjacent forming units can be a single module or multiple modules connected sequentially. The arrangement of the heat-treated module 2 within the second forming module 12 is similar to its arrangement within the first forming module 11 and will not be repeated here. The heat-treated module 2 arranged between the first forming module 11 and the second forming module 12 can be a single module or multiple modules connected sequentially.

[0036] It is conceivable that when both the first molding module 11 and the second molding module 12 are provided with a molding machine unit, the fire-resistant module 2 is provided between the first molding module 11 and the second molding module 12 to connect the molding machine unit of the first molding module 11 and the molding machine unit of the second molding module 12.

[0037] Please see Figure 1In the first embodiment of this utility model, the molding unit of the second molding module 12 is a cyclic molding unit 121, which can perform multiple molding operations cyclically. The second molding module 12 also includes an input mechanism 122 and an output mechanism 123, and the input mechanism 122, the cyclic molding unit 121, and the output mechanism 123 are connected in sequence. The output mechanism 123 is used to output the tea leaves outward. The molding unit of the first molding module 11 is a linear molding unit 111, which can perform one molding operation. The first molding module 11 includes at least two linear molding units 111 arranged in sequence. A pair of adjacent linear molding units 111 are connected by a heat transfer module 2, and the first linear molding unit 111 is used to receive the tea leaves input from the outside, and the last linear molding unit 111 is connected to the input mechanism 122.

[0038] In this tea forming production line, the tea leaves are first shaped gradually by linear forming units 111. The tea leaves are then subjected to a heat treatment between a pair of adjacent linear forming units 111, which improves the quality and plasticity of the tea. Subsequently, the tea leaves are stacked and consolidated within the circulating forming unit 121, and finally, the tea leaves are output. The circulating forming unit 121 is suitable for scenarios requiring multiple forming operations, avoiding the problem of an excessively long overall production line size caused by using only linear forming units 111, thus contributing to a more compact overall production line layout.

[0039] In this embodiment, the first molding module 11 includes four linear molding units 111 arranged in sequence, and a heat treatment module 2 is arranged between the second linear molding unit 111 and the third linear molding unit 111.

[0040] Please see Figure 1 and Figure 3 In a specific embodiment, the heat treatment module 2 includes a heat treatment machine 21, a first elevator 22, and a second elevator 23. The heat treatment machine 21 has an inlet 2122 and an outlet 2123. The first elevator 22 is used to receive tea leaves output from the preceding linear forming machine 111 of two adjacent linear forming machine units 111 and transport the tea leaves to the inlet 2122 of the heat treatment machine 21. The second elevator 23 is used to receive tea leaves output from the outlet 2123 of the heat treatment machine 21 and transport the tea leaves to the following linear forming machine unit 111 of two adjacent linear forming machine units 111. The arrangement of the first elevator 22 and the second elevator 23 can stably transport tea leaves from one linear forming machine unit 111 to the heat treatment machine 21 for heat treatment according to the layout and height requirements of the production line, and then transport the heat-treated tea leaves to another linear forming machine unit 111, thereby ensuring the continuity and stability of the production line.

[0041] Please see Figure 2 In the second embodiment of this utility model, the molding unit of the second molding module 12 is a cyclic molding unit 121, which can perform multiple molding operations cyclically. The second molding module 12 also includes an input mechanism 122 and an output mechanism 123, and the input mechanism 122, the cyclic molding unit 121, and the output mechanism 123 are connected in sequence. The output mechanism 123 is used to output the tea leaves outward. The molding unit of the first molding module 11 is a linear molding unit 111, which can perform one molding operation. The first molding module 11 includes at least two linear molding units 111 arranged in sequence, and each linear molding unit 111 is connected in sequence. The first linear molding unit 111 is used to receive the tea leaves input from the outside, and the last linear molding unit 111 is connected to the input mechanism 122 through the heat treatment module 2.

[0042] In this tea forming production line, the tea leaves are first shaped gradually by a linear forming unit 111. The tea leaves are then subjected to a heat treatment between adjacent linear forming units 111 and a circulating forming unit 121. This heat treatment improves the quality and plasticity of the tea leaves. Subsequently, the tea leaves are stacked and consolidated within the circulating forming unit 121, and finally, the tea leaves are output. The circulating forming unit 121 is suitable for scenarios requiring multiple forming operations, avoiding the problem of an excessively long overall production line size caused by using only linear forming units 111, thus contributing to a more compact overall production line layout.

[0043] In this embodiment, the first molding module 11 includes two linear molding units 111 arranged in sequence, and two heat treatment modules 2 are connected in sequence between the second linear molding unit 111 and the input mechanism 122.

[0044] Please see Figure 2 and Figure 3 In a specific embodiment, the heat treatment module 2 includes a heat treatment machine 21, a first elevator 22, and a second elevator 23. The heat treatment machine 21 is provided with an inlet 2122 and an outlet 2123. The first elevator 22 is used to receive the tea leaves output from the last linear forming unit 111 in the first forming module 11 and transport the tea leaves to the inlet 2122 of the heat treatment machine 21. The second elevator 23 is used to receive the tea leaves output from the outlet 2123 of the heat treatment machine 21 and transport the tea leaves to the input mechanism 122.

[0045] The first elevator 22 and the second elevator 23 are configured to stably transport tea leaves from the last linear forming unit 111 to the firing machine 21 for firing, according to the layout and height requirements of the production line. The fired tea leaves are then transported to the input mechanism 122, and subsequently to the circulating forming unit 121, thereby ensuring the continuity and stability of the production line.

[0046] Please see Figure 2 In a specific embodiment, the tea forming production line also includes a cooling module 3. The second elevator 23 conveys the tea to the input mechanism 122 through the cooling module 3. The cooling module 3 includes a cooler 31 and a third elevator 32. The cooler 31 includes an inlet and a outlet. The inlet is used to receive the tea conveyed by the second elevator 23, and the third elevator 32 is used to receive the tea output from the outlet of the cooler 31 and convey the tea to the input mechanism 122.

[0047] After being heated, the tea leaves are usually at a high temperature and cannot be directly fed into the circulating forming unit 121. They need to be cooled in the heating module 2. The cooling module 3, as a transition link between the heating module and the input mechanism 122, uses a cooler 31 to quickly reduce the temperature of the tea leaves. Then, the third elevator 32 smoothly conveys the cooled tea leaves to the circulating forming unit 121, forming a continuous process of "forming → heating → cooling → forming". This further shortens the production cycle and improves the overall efficiency of the forming process.

[0048] It should be noted that the cooling module 3 can be similarly set in the first embodiment. The second elevator 23 conveys the tea leaves to the next linear forming unit 111 of the two adjacent linear forming units 111 through the cooling module 3. The specific structural arrangement can be referred to the above description, and will not be elaborated on here.

[0049] Please see Figure 1 and Figure 2 In the above embodiments, the linear forming machine unit 111 includes a forming machine 1211, a fourth conveying mechanism 1111 and a deblocking machine 1213 connected in sequence, and the deblocking machine 1213 of the first linear forming machine unit 111 and the forming machine 1211 of the second linear forming machine unit 111 are connected through the fifth conveying mechanism 1112.

[0050] Specifically, when the last linear forming unit 111 is connected to the input mechanism 122 via the heat transfer module 2, the first elevator 22 of the heat transfer module 2 is used to receive the tea leaves output from the de-blocking machine 1213 of the last linear forming unit 111. When the first elevator 22 is connected between two adjacent linear forming units 111 via the heat transfer module 2, the first elevator 22 is used to receive the tea leaves output from the de-blocking machine 1213 of the previous linear forming unit 111, and the second elevator 23 is used to transport the tea leaves to the forming machine 1211 of the next linear forming unit 111.

[0051] In a specific embodiment, both the input mechanism 122 and the output mechanism 123 extend along the first horizontal direction D1 and are arranged at intervals on the second horizontal direction D2, and the second horizontal direction D2 is perpendicular to the first horizontal direction D1.

[0052] The recycling forming unit 121 is provided in several groups, with each recycling forming unit 121 arranged side by side at intervals in the first horizontal direction D1, and located between the input mechanism 122 and the output mechanism 123 in the second horizontal direction D2. While the input mechanism 122 and the output mechanism 123 can respectively connect to multiple recycling forming units 121, a compact layout is formed, thereby reducing the space occupied and optimizing the tea leaf transfer path.

[0053] In a specific embodiment, the circulating forming unit 121 includes a forming machine 1211, a first conveying mechanism 1212, a de-blocking machine 1213, a second conveying mechanism 1214, and a third conveying mechanism 1215. The forming machine 1211, the first conveying mechanism 1212, and the de-blocking machine 1213 are connected in sequence, and the second conveying mechanism 1214 and the input mechanism 122 are respectively connected to the forming machine 1211. The third conveying mechanism 1215 is used to selectively convey the tea leaves output by the de-blocking machine 1213 to the second conveying mechanism 1214 or the output mechanism 123.

[0054] The forming machine 1211 is used to knead the tea leaves, and the de-clumping machine 1213 is used to de-clump the tea leaves. The tea leaves output from the last linear forming unit 111 or the overheating module 2 are transferred via the input mechanism 122 to the forming machine 1211 of any circulating forming unit 121. They pass sequentially through the forming machine 1211, the first conveying mechanism 1212, and the de-clumping machine 1213. Subsequently, they are selectively conveyed by the third conveying mechanism 1215 to the second conveying mechanism 1214 or to the output mechanism 123. In the latter case, the tea leaves are conveyed by the third conveying mechanism 1215 to the second conveying mechanism 1214, and then by the second conveying mechanism 1214 back to the forming machine 1211 for kneading, thus cyclically performing the "kneading-de-clumping" action. When the tea leaves are conveyed to the output mechanism 123 by the third conveyor belt, the forming operation of the tea leaves in the circulating forming unit 121 ends, thereby providing a specific and feasible structural design for the circulating forming unit 121.

[0055] In a specific embodiment, the forming machine 1211 and the first conveying mechanism 1212, as well as the second conveying mechanism 1214 and the de-blocking machine 1213, are all arranged side by side in the first horizontal direction D1. The forming machine 1211 and the second conveying mechanism 1214, as well as the first conveying mechanism 1212 and the de-blocking machine 1213, are all arranged side by side in the second horizontal direction D2. The third conveying mechanism 1215 is located in the second horizontal direction D2 of the second conveying mechanism 1214 and the de-blocking machine 1213, and extends along the first horizontal direction D1. The forming machine 1211 is located on the side closer to the input mechanism 122 in the second horizontal direction D2, and the third conveying mechanism 1215 is located on the side closer to the output mechanism 123 in the second horizontal direction D2. This arrangement ensures that each mechanism operates independently, reduces mechanical interference, has a compact layout, and further optimizes the path of tea leaves transferred between the input mechanism 122, the circulating forming unit 121, and the output mechanism 123.

[0056] Please see Figure 3 In a specific embodiment, the heat treatment machine 21 includes a base 211, a drum 212, and a heating furnace 213. The base 211 has a protective cavity 2111 with a downward-facing opening 2112. A guide plate with a downward inclination is provided directly below the opening 2112. The drum 212 is horizontally arranged and hollow inside to form a heat treatment channel 2121. The two ends of the heat treatment channel 2121 are a feed inlet 2122 and a discharge outlet 2123, respectively. Several sieve holes 2124 are opened on the peripheral wall of the drum 212, which are respectively connected to the heat treatment channel 2121. The drum 212 is rotatably disposed in the protective cavity 2111. The heating furnace 213 is connected to the heat treatment channel 2121 and is used to provide hot air to the heat treatment channel 2121.

[0057] Tea leaves enter the heat treatment channel 2121 through the feed inlet 2122. The heating furnace 213 operates to send hot air into the heat treatment channel 2121. At the same time, the drum 212 rotates in the protective chamber 2111, causing the tea leaves in the heat treatment channel 2121 to be continuously turned over in the heat treatment channel 2121 under the action of gravity, centrifugal force and airflow. This allows the tea leaves to be heated evenly under the action of hot air, so as to lose some moisture. The tea leaves that have completed the heat treatment leave the heat treatment channel 2121 through the discharge outlet 2123, so that they can be put into the next process. During this process, because the drum 212 has several sieving holes 2124 on its peripheral wall that are connected to the sieving channel 2121, as the tea leaves are turned over in the sieving channel 2121, the tea dust, due to its light weight and small volume, can be discharged from the sieving channel 2121 through the sieving holes 2124 under the action of centrifugal force, gravity, and airflow. The protective cavity 2111 prevents the tea dust from splashing in all directions. The tea dust can be concentrated at the opening 2112 of the protective cavity 2111 and fall naturally under the action of gravity onto the inclined guide plate located below the opening 2112, and then discharged in a directional manner through the guide plate for subsequent collection or cleaning. Thus, the sieving machine 21 integrates the functions of sieving and dust screening, which can reduce costs and improve overall production efficiency.

[0058] Please see Figure 4 In a specific embodiment, the inner wall of the fire passage 2121 is provided with protruding strips 2125 and guide vanes 2126. The protruding strips 2125 extend along the extension direction of the fire passage 2121 and are provided in several ways, and each protruding strip 2125 is arranged circumferentially at intervals. Between two adjacent protruding strips 2125, there are several guide vanes 2126 that are distributed at intervals along the extension direction of the fire passage 2121, and the guide vanes 2126 are arranged in an inclined manner.

[0059] The protruding strip 2125 is used to flip the tea leaves in the heat-exposing channel 2121 upward when the drum 212 rotates, so as to heat the tea leaves more evenly. The inclined guide plate 2126 can generate a small axial force on the tea leaves when the drum 212 rotates, which helps the tea leaves move slowly towards the discharge port 2123. Furthermore, with the cooperation of several guide plates 2126 that are spaced apart along the extension direction of the heat-exposing channel 2121, the tea leaves input from the feed port 2122 can be output from the discharge port 2123, without the need to manually or mechanically lift the drum 212 to discharge the tea leaves, thus simplifying the structural design and operation steps.

[0060] In this embodiment, the protrusion 2125 extends from the feed inlet 2122 to the discharge outlet 2123.

[0061] In a further embodiment, several protruding strips 2125 divide the inner wall of the fire passage 2121 into several circumferentially arranged side sections. Each side section is provided with several guide vanes 2126, and the guide vanes 2126 on adjacent side sections are staggered. The guide vanes 2126 on two side sections separated by one side section are aligned, so that the tea leaves can complete the movement from the feed inlet 2122 to the discharge outlet 2123 through a more complex path, thereby promoting the full mixing of the tea leaves in the fire passage 2121 and obtaining a more uniform fire-testing effect.

[0062] It should be noted that the cooling machine 31 in the cooling module 3 is designed with reference to the heat exchanger 21 in the above embodiment. In a specific embodiment, the only difference between the cooling machine 31 and the heat exchanger 21 is that the heating furnace 213 in the heat exchanger 21 is replaced with a blower that provides cold air. Specifically, while the tea leaves are cooled in the cooling machine 31, the broken pieces can be screened out again, thereby further improving the overall production efficiency.

[0063] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
