Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and more specifically, to a heat-pressing machine. Background Technology

[0002] Tea leaves undergo multiple shaping processes, and at appropriate intervals between these processes, they need to be briefly heated in a firing device. This process causes the tea leaves to lose moisture and change their plasticity, which is beneficial for the gradual tightening of the leaves in subsequent shaping operations. Existing firing equipment mainly uses the rotation of drums to tumble the tea leaves inside, ensuring even heating. However, this tumbling process can generate some dust, which mixes with the tea leaves. After firing, the tea leaves must be sieved through a dust-sieving device to remove the dust, which is cumbersome and time-consuming. Utility Model Content

[0003] The purpose of this invention is to provide a heat treatment machine, which solves the technical problem of how to simplify the heat treatment and sieving operations and reduce time costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] This utility model provides a heat-passing machine, comprising: a base, wherein the base has a protective cavity with a downward-facing opening, and a downwardly inclined guide plate is provided directly below the opening; a roller, which is horizontally arranged and hollow to form a heat-passing channel, wherein the two ends of the heat-passing channel are a feed inlet and a discharge outlet, and the roller has a plurality of sieving holes on its peripheral wall that are respectively connected to the heat-passing channel, and the roller is rotatably disposed in the protective cavity; and a heating furnace, which is connected to the heat-passing channel and is used to provide hot air to the heat-passing channel.

[0006] In some embodiments of this application, the base includes a base, a shield, a baffle, and a guide plate. The shield, baffle, and guide plate are all connected to the base. The baffle is located below the shield and is arranged horizontally side by side at intervals. The arrangement direction of the two baffles is perpendicular to the extension direction of the roller. The two baffles and the shield enclose the protective cavity, and the opening is formed between the lower ends of the two baffles. The roller is rotatably connected to the base so as to be rotatably disposed in the protective cavity.

[0007] In some embodiments of this application, the mask is a semi-cylindrical structure.

[0008] In some embodiments of this application, the baffle includes a first baffle arranged vertically and a second baffle arranged at an incline, and the horizontal spacing between the second baffles of the two baffles gradually decreases from top to bottom, and the opening is formed between the lower ends of the second baffles of the two baffles.

[0009] In some embodiments of this application, the guide plate is arranged at a downward angle from the side where one of the baffles is located to the side where the other baffle is located.

[0010] In some embodiments of this application, the inner wall of the fire passage is provided with protruding strips and guide vanes;

[0011] The convex strips extend along the extension direction of the fire passage and are provided in a plurality of them, and each of the convex strips is arranged circumferentially. Between two adjacent convex strips, there are a plurality of guide vanes that are spaced apart along the extension direction of the fire passage and are arranged in an inclined manner.

[0012] In some embodiments of this application, several of the protruding strips divide the inner wall of the fire passage into several circumferentially arranged side portions. Each side portion is provided with several guide vanes, and the guide vanes on adjacent side portions are staggered, while the guide vanes on two side portions separated by one side portion are aligned.

[0013] In some embodiments of this application, the roller includes a main body and two extensions connected to the main body and located on both sides of the main body axially, and the fire passage is formed in the main body and the two extensions; the main body is located in the protective cavity and has the sieve hole, the two extensions extend out of the protective cavity, and the ends of the two extensions away from the main body are the feed inlet and the discharge outlet, respectively.

[0014] In some embodiments of this application, the heat treatment machine further includes a feeding hopper, a first elevator, and a second elevator. The feeding hopper is installed at the feed inlet and communicates with the heat treatment channel through the feed inlet. The discharge port of the feeding hopper faces upward, and the feeding hopper is communicated with the heating furnace. The first elevator is used to lift the tea leaves upward and transport them to the discharge port of the feeding hopper. The second elevator is used to receive the tea leaves falling from the discharge port and lift them upward.

[0015] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0016] In this embodiment of the fire-passing machine, tea leaves enter the fire-passing channel through the feed inlet. The heating furnace operates to send hot air into the fire-passing channel. Simultaneously, the drum rotates within the protective chamber, causing the tea leaves in the fire-passing channel to be continuously tumbled under the action of gravity, centrifugal force, and airflow. This allows the tea leaves to be heated evenly under the action of hot air, thus dissipating some moisture. The fire-passing tea leaves then leave the fire-passing channel through the discharge outlet, ready for the next process. During this process, because the drum's peripheral wall has several sieve holes that communicate with the fire-passing channel, as the tea leaves are tumbled within the fire-passing channel, the broken pieces, due to their light weight and small volume, can be discharged through the sieve holes under the action of centrifugal force, gravity, and airflow. The protective chamber prevents the broken pieces from splashing outwards, allowing them to be concentrated at the opening of the protective chamber and naturally fall onto the inclined guide plate located below the opening under gravity, where they are directionally discharged for subsequent collection or cleaning. Therefore, this tea-processing machine integrates the tea-processing and sieving equipment, allowing the tea leaves to be naturally sifted during the tea-processing process without interference between the two operations. This simplifies the tea-processing and sieving process and reduces time costs. Furthermore, compared to using separate tea-processing and sieving equipment, the integrated design also helps save on equipment procurement costs. Attached Figure Description

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.

[0031] 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.

[0032] 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.

[0033] Please see Figures 1 to 3The heat-passing machine provided in one embodiment of this utility model mainly includes a base 1, a drum 2, and a heating furnace 3. The base 1 has a protective cavity 15 with a downward-facing opening 16. A downwardly inclined guide plate 14 is located directly below the opening 16. The drum 2 is horizontally arranged and hollow to form a heat-passing channel 23. The two ends of the heat-passing channel 23 are an inlet 231 and an outlet 232, respectively. Several sieve holes 211 are formed on the peripheral wall of the drum 2, each communicating with the heat-passing channel 23. The drum 2 is rotatably disposed within the protective cavity 15. The heating furnace 3 is connected to the heat-passing channel 23 and is used to supply hot air to the heat-passing channel 23.

[0034] In the frying machine of this utility model embodiment, tea leaves enter the frying channel 23 through the feed inlet 231. The heating furnace 3 works to send hot air into the frying channel 23. At the same time, the roller 2 rotates in the protective cavity 15, so that the tea leaves in the frying channel 23 are continuously turned over in the frying channel 23 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 frying tea leaves leave the frying channel 23 through the discharge outlet 232 so that they can be put into the next process. During this process, because the roller 2 has several sieving holes 211 on its peripheral wall that are connected to the sieving channel 23, as the tea leaves are turned over in the sieving channel 23, the tea dust, due to its light weight and small volume, can be discharged from the sieving channel 23 through the sieving holes 211 under the action of centrifugal force, gravity, and airflow. The protective cavity 15 prevents the tea dust from splashing in all directions. The tea dust can be concentrated at the opening 16 of the protective cavity 15 and fall naturally onto the inclined guide plate 14 located below the opening 16 under the action of gravity, and is discharged directionally through the guide plate 14 for subsequent collection or cleaning. Thus, this sieving machine integrates the sieving equipment and the dust-sieving equipment, allowing the tea leaves to be naturally sieved during the sieving process, and the sieving and dust-sieving operations do not interfere with each other, thereby simplifying the sieving and dust-sieving operations and reducing time costs. On the other hand, compared with using the sieving equipment and dust-sieving equipment separately, the integrated setup also helps to save on equipment procurement costs.

[0035] It should be noted that collection troughs or similar features located below opening 16 should also be included within the scope of protection of this utility model application.

[0036] It is conceivable that the protective cavity 15 also serves to prevent excessive heat loss.

[0037] Please see Figure 1In one embodiment where a protective cavity 15 is provided within the aforementioned machine base 1, the machine base 1 includes a base 11, a shield 12, a baffle 13, and a guide plate 14. The shield 12, baffle 13, and guide plate 14 are all connected to the base 11. Two baffles 13 are located below the shield 12 and are arranged horizontally side-by-side at intervals. The arrangement direction of the two baffles 13 is perpendicular to the extension direction of the roller 2. The two baffles 13 and the shield 12 enclose the protective cavity 15, and an opening 16 is formed between the lower ends of the two baffles 13. The roller 2 is rotatably connected to the base 11 and rotatably disposed within the protective cavity 15. The base 11 provides basic support for the overall structure, while the two baffles 13 and the shield 12 form a semi-enclosed protective cavity 15, thus providing a practical and feasible structural design for the machine base 1.

[0038] In other embodiments, the base 1 may be an integral structure with a protective cavity 15, which will not be described in detail here.

[0039] In a specific embodiment, the shield 12 has a semi-cylindrical structure. The inner curved surface of the shield 12 has a natural guiding effect on the upwardly sprayed debris. After impacting the inner curved surface, the debris can slide down the arc surface to the baffle 13 and flow out from the opening 16 formed between the lower ends of the two baffles 13 under the action of gravity. The semi-cylindrical structure of the shield 12 can also be adapted to the shape of the roller 2, making the overall appearance more compact and beautiful.

[0040] In a specific embodiment, the baffle 13 includes a vertically arranged first baffle 131 and an inclined second baffle 132 arranged sequentially from top to bottom, and the horizontal interval between the second baffles 132 of the two baffles 13 gradually decreases from top to bottom. An opening 16 is formed between the lower ends of the second baffles 132 of the two baffles 13. The inclined second baffle 132 plays the role of guiding the debris to fall effectively into the guide plate 14 below the opening 16.

[0041] In a specific embodiment, the guide plate 14 is arranged at an angle downward from the side where one of the baffles 13 is located to the side where the other baffle 13 is located. The arrangement of the guide plate 14 can effectively cooperate with the action of the debris splashing out from the sieve hole 211 on the peripheral wall when the drum 2 rotates, so as to facilitate the collection of debris and reduce the accumulation of debris on the guide plate 14.

[0042] In other embodiments, the guide plate 14 may be inclined downward relative to the extending direction of the roller 2.

[0043] Please see Figure 4In a specific embodiment, the inner wall of the fire passage 23 is provided with protruding strips 24 and guide vanes 25. The protruding strips 24 extend along the extension direction of the fire passage 23 and are provided in several ways, and each protruding strip 24 is arranged circumferentially. Between two adjacent protruding strips 24, there are several guide vanes 25 that are distributed at intervals along the extension direction of the fire passage 23, and the guide vanes 25 are arranged in an inclined manner.

[0044] The protruding strip 24 is used to flip the tea leaves in the heat-exposing channel 23 upward when the drum 2 rotates, so as to heat the tea leaves more evenly. The inclined guide plate 25 can generate a small axial force on the tea leaves when the drum 2 rotates, which helps the tea leaves to move slowly towards the discharge port 232. Furthermore, with the cooperation of several guide plates 25 that are spaced apart along the extension direction of the heat-exposing channel 23, the tea leaves input from the feed port 231 can be output from the discharge port 232, without the need to manually or mechanically lift the drum 2 to discharge the tea leaves, thus simplifying the structural design and operation steps.

[0045] In this embodiment, the protrusion 24 extends from the feed inlet 231 to the discharge outlet 232.

[0046] In a specific embodiment, several protruding strips 24 divide the inner wall of the fire passage 23 into several circumferentially arranged side portions 26. Each side portion 26 is provided with several guide vanes 25, and the guide vanes 25 on adjacent side portions 26 are staggered. The guide vanes 25 on two side portions 26 separated by one side portion 26 are aligned, so that the tea leaves can complete the movement from the feed inlet 231 to the discharge outlet 232 through a more complex path, so as to promote the full mixing of the tea leaves in the fire passage 23 and thus obtain a more uniform fire effect.

[0047] It should be noted that the guide vane 25 can be rectangular or curved.

[0048] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In a specific embodiment, the roller 2 includes a main body 21 and two extensions 22 connected to the main body 21 and located on both axial sides of the main body 21. A fire passage 23 is formed within the main body 21 and the two extensions 22. The main body 21 is located within a protective cavity 15 and has a sieve hole 211. The two extensions 22 extend out of the protective cavity 15, with the ends of the two extensions 22 furthest from the main body 21 being an inlet 231 and an outlet 232, respectively. The extensions 22 provide a buffer zone for the feeding and discharging of tea leaves and ensure that the inlet 231 and outlet 232 are not obstructed by the protective cavity 15, allowing for smooth communication with external structures.

[0049] In this embodiment, the main body 21 is a stainless steel mesh.

[0050] Please see Figure 1 , Figure 3 and Figure 5 In this embodiment, the two extensions 22 are provided with annular grooves 221 arranged around their outer periphery, and the base 11 is provided with rollers 111 that respectively cooperate with the annular grooves 221 of the two extensions 22, so that the rollers 2 and the base 11 are rotatably connected.

[0051] Please see Figures 1 to 3 In a specific embodiment, the heat treatment machine also includes a feed hopper 4, a first elevator 5, and a second elevator 6. The feed hopper 4 is installed at the feed inlet 231 and is connected to the heat treatment channel 23 through the feed inlet 231. The discharge port of the feed hopper 4 faces upward, and the feed hopper 4 is connected to the heating furnace 3. The first elevator 5 is used to lift the tea leaves upward and transport them to the discharge port of the feed hopper 4. The second elevator 6 is used to receive the tea leaves falling from the discharge port 232 and lift them upward. The arrangement of the first elevator 5 and the second elevator 6 facilitates the seamless connection of the heat treatment machine with other equipment, thereby forming a complete material flow path and realizing automated continuous production.

[0052] In this embodiment, the feed hopper 4 is provided with an air inlet 41 for connecting with the heating furnace 3.

[0053] 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.
