Description

Technical Field

[0001] This utility model relates to the field of tea processing, specifically to a heating mechanism for continuous drying of tea. Background Technology

[0002] Tea drying machines are indispensable equipment in the tea processing process. They are mainly used to quickly and evenly dry freshly picked leaves using hot air or other heating methods to achieve the required moisture content, thereby maintaining the quality of the tea and extending its shelf life.

[0003] Existing tea drying machines typically have a hot air blower positioned below the front end of the tea conveyor path. This blower directs hot air upwards onto the tea leaves, which are then conveyed backwards. The hot air blower below the front end of the conveyor path continuously dries the tea, achieving a continuous drying effect. However, to ensure the drying effect of the tea leaves along the conveyor path, the conveyor speed must be controlled at a low speed. This results in low efficiency for batch drying of tea leaves. Furthermore, drying tea leaves at a single fixed point often leads to uneven heating, inconsistent drying results, and some leaves becoming damp, resulting in poor quality.

[0004] Therefore, to solve the above problems, a heating mechanism for continuous tea drying is needed to address these production issues. Utility Model Content

[0005] In view of this, the heating mechanism for continuous tea drying in this technical solution provides uniform heating and drying conditions for the tea on the entire tea conveying mechanism by installing a heating device on the side wall of the hot air chamber and introducing hot air to the air inlet of the large fan through the heating device, thereby ensuring the quality of the dried tea and improving production efficiency.

[0007] Furthermore, the heating device is configured as multiple devices with the same structure, and the multiple heating devices are evenly distributed along the length direction of the conveying mechanism, and the heating device is installed on the side of the hot air chamber.

[0008] Furthermore, the heating device includes a mounting frame arranged on the side of the hot air chamber, a support frame protruding from the mounting frame, a heating tube mounted on the support frame, and a small fan, wherein the mounting frame has a mounting position for mounting the small fan.

[0009] Furthermore, the support frame has a rectangular cross-section along the length of the conveying mechanism, and the support frame has heating pipe mounting holes for installing heating pipes. There are multiple heating pipes, and the multiple heating pipes are evenly distributed along the height of the support frame. The small fan is used to deliver external air to the heating pipes for heating.

[0010] Furthermore, a large fan is installed at the top of the hot air chamber, which is used to guide hot air from below to the conveying mechanism to dry the tea leaves.

[0011] Furthermore, it also includes a temperature detection device mounted on the frame, the temperature detection device including a length guide rod assembly, a width guide rod assembly and a temperature detector mounted on the frame, the width guide rod assembly being adjustablely mounted on the length guide rod assembly, and the temperature detector being adjustablely mounted on the width guide rod assembly.

[0021] Figure 1 This is an isometric schematic diagram of the heating device of this utility model; Figure 2 This is a top view of the present invention; Figure 3 This is a top view of the internal installation of the large fan in this utility model; Figure 4This is a schematic diagram of the hot air chamber layout of this utility model; Figure 5 This is a front view of the present utility model; Figure 6 This is a schematic diagram of the installation of the small fan of this utility model; as shown in the figure, a heating mechanism for continuous tea drying includes a hot air chamber 7 arranged at the lower end of the conveying mechanism 2 and a heating device used in conjunction with the hot air chamber 7; the heating device is used to convey hot air to the hot air chamber 7, and the hot air chamber 7 is used to provide continuous hot air and heat and dry the tea; the heating mechanism for continuous tea drying of this technical solution continuously sets multiple large fans in the hot air chamber below the tea conveying mechanism 2 (which adopts a conveyor belt structure, and an existing conveying structure can be used; the conveyor belt of the conveying mechanism 2 is breathable to facilitate the hot airflow to dry the tea) and sets heating devices on the side walls of the hot air chamber. The heating devices introduce hot air into the air inlet of the large fans, providing uniform heating and drying conditions for the tea on the entire tea conveying mechanism, ensuring the quality of the dried tea, and improving production efficiency.

[0022] In this embodiment, multiple heating devices 5 with identical structures are evenly distributed along the length of the conveying mechanism. The heating devices 5 are installed on the side of the hot air chamber 7, and the large fan 4 is arranged above the hot air chamber 7. The heating devices 5 are used to heat the air and guide it to the air inlet of the large fan 4. Multiple large fans 4 are provided and evenly arranged along the length of the frame, positioned directly above the hot air chamber 7. This facilitates the upward introduction of heated air from the hot air chamber 7 onto the conveying mechanism 2 for heating and drying the tea leaves. Multiple hot air chambers 7 are correspondingly provided, forming a one-to-one arrangement with the large fans.

[0023] In this embodiment, the heating device 5 includes a mounting frame 53 arranged on the side of the hot air chamber, a support frame 54 protruding from the mounting frame, a heating pipe 52 mounted on the support frame 54, and a small fan 51. The mounting frame has a mounting position for mounting the small fan. The mounting frame 53 is installed in conjunction with the hot air chamber 7. The mounting frame 53 has a frame structure. The small fan 51 is installed inside the mounting frame 53 to introduce external air into the hot air chamber 7. A support frame structure is installed on the inner end face of the mounting frame 53 for mounting the heating pipe 52. When the small fan and heating pipe are running, the small fan can draw in outside air and heat it through the heating pipe, thereby increasing the air convection speed.

[0024] In this embodiment, the support frame has a rectangular cross-section along its length. The support frame has heating pipe mounting holes 55 for installing heating pipes 52. Multiple heating pipes 52 are evenly distributed along the height of the support frame. The small fan 51 is used to deliver external air to the heating pipes for heating. The support frame itself also adopts a rectangular frame structure with multiple heating pipe mounting holes 55 for facilitating the arrangement of multiple heating pipes. Alternatively, the heating pipes can be selected as heating meshes and installed on the support frame, depending on the actual situation.

[0025] In this embodiment, a smoothing device 3 is also installed on the frame 1. The smoothing device 3 flips and scrapes the tea leaves to ensure that the thickness of the tea leaves stacked on the conveyor belt is consistent, so that the tea leaves are heated evenly. At the same time, the smoothing device also has a dispersing function, so that the tea leaves are distributed loosely and the shape is more conducive to heating (the smoothing device 3 can adopt the structure in the prior art).

[0026] In this embodiment, a temperature detection device 6 is also included, which is mounted on the frame. The temperature detection device includes a length guide rod assembly 62, a width guide rod assembly 61, and a temperature detector 64, all mounted on the frame 1. The width guide rod assembly is adjustablely mounted on the length guide rod assembly 62, and the temperature detector 64 is adjustablely mounted on the width guide rod assembly 61. The width guide rod assembly 61 is mounted on the length guide rod assembly 62 via the mounting base 63. The temperature detector 64 is mounted in conjunction with the width guide rod assembly 61 and can be adjusted in position along the width direction (either using a slide rail slider or a screw and nut assembly, which is the prior art). The length guide rod assembly 62, together with the mounting base 63, can form a ball screw structure or other structures (the prior art is used here). This allows the temperature detector 64 to detect temperature not only along the length direction but also along the width direction. The temperature detector 64 can collect the real-time temperature of the tea leaves and then adjust the power of the heating module by comparing the real-time temperature of the tea leaves with a preset range. If the temperature is less than the minimum value of the temperature range, the heating efficiency of the heating tube can be increased; if the temperature is greater than or equal to the maximum value of the temperature range, the heating efficiency of the heating tube can be decreased or even the heating tube can be turned off.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
