Description

Technical Field

[0001] This utility model relates to the field of tea processing, specifically to a continuous tea drying machine. 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 at the front end of the conveyor path dries different types of 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, since the thickness of the tea leaves piled up at different locations along the conveyor path may vary, this can lead to uneven heating and inconsistent drying results, with some tea leaves becoming damp and resulting in poor quality.

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

[0005] In view of this, the continuous tea dryer of this technical solution continuously installs multiple large fans in the hot air chamber below the tea conveying mechanism, and installs heating devices on the side wall 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.

The large fan is arranged above the hot air chamber, and the heating component is used to heat the air and guide it to the air inlet of the large fan.

[0008] Furthermore, the heating assembly 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 frame, 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, it also includes a smoothing device mounted on the frame, the smoothing device including a cover mounted on the frame, a smoothing frame used in conjunction with the cover, and a smoothing adjustment component mounted in conjunction with the smoothing frame, the smoothing adjustment component being adjustable in the vertical direction.

[0011] Furthermore, the smoothing adjustment assembly includes a sliding seat mounted on the smoothing frame, an adjusting screw mounted in conjunction with the sliding seat, and a rotating bracket mounted on the sliding seat. The adjusting screw and the sliding seat form a screw-nut pair and can adjust the installation height of the sliding seat.

The heating device introduces hot air into the air inlet of the large fan, 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.

[0027] In this embodiment, the heating devices 5 are multiple devices with identical structures, and these heating devices 5 are evenly distributed along the length of the conveying mechanism. Each heating device 5 includes a hot air chamber 7 mounted on the frame 1 and a heating assembly mounted on the side of the hot air chamber 7. The large fan 4 is arranged above the hot air chamber 7. The heating assembly 5 is used to heat the air and guide it to the air inlet of the large fan 4. Multiple large fans 4 are provided, and these large fans 4 are evenly arranged along the length of the frame. The large fans 4 are arranged directly above the hot air chamber 7, which facilitates the upward introduction of the heated air in the hot air chamber 7 onto the conveying mechanism 2 for heating and drying the tea leaves. The hot air chamber 7 is correspondingly provided in multiple ways, forming a one-to-one arrangement with the large fans.

[0028] In this embodiment, the heating assembly 5 includes a mounting frame 53 arranged on the side of the hot air chamber, a support frame protruding from the mounting frame, a heating pipe 52 mounted on the support frame, and a small fan 51. The mounting frame has a mounting position for mounting the small fan. Figure 4-6 As shown, the mounting frame 53 is installed in conjunction with the hot air chamber 7. The mounting frame 53 is 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 installing the heating tube 52. When the small fan and heating tube are running, the small fan can draw in outside air and heat it through the heating tube, thereby increasing the air convection speed.

[0029] In this embodiment, the support frame is along the length of the frame (i.e. Figure 1 The cross-section (horizontal direction) is generally rectangular. The support frame has mounting holes for heating tubes 52. Multiple heating tubes 52 are evenly distributed along the height of the support frame. The small fan 51 is used to deliver external air to the heating tubes for heating. The support frame also adopts a rectangular frame structure with multiple mounting holes for facilitating the arrangement of multiple heating tubes. Alternatively, heating tubes can be selected as heating meshes and installed on the support frame, depending on the actual situation.

[0030] In this embodiment, a smoothing device 3 is also included, mounted on the frame 1. The smoothing device 3 includes a protective cover 31 mounted on the frame 1, a smoothing frame 35 used in conjunction with the protective cover 31, and a smoothing adjustment assembly mounted in conjunction with the smoothing frame 35. The smoothing adjustment assembly is adjustable in the vertical direction. Figure 7 , 8 As shown, the protective cover 31 is installed on the frame 1, and the smoothing frame 35 is also installed in conjunction with the frame 1. The protective cover 31 has an opening for tea leaves to pass through, which facilitates the conveying of tea leaves to the conveyor belt. The smoothing adjustment component can be adjusted along the vertical height of the smoothing frame 35.

[0031] In this embodiment, the smoothing adjustment assembly includes a sliding seat 34 mounted on a smoothing frame 35, an adjusting screw 36 mounted in conjunction with the sliding seat 34, and a rotating bracket 33 mounted on the sliding seat 34. The adjusting screw 36 and the sliding seat 34 form a screw-nut pair, which can adjust the installation height of the sliding seat. The rotating bracket is used to flip and smooth the tea leaves and output them from the protective cover. The sliding seat 34 is mounted in conjunction with the adjusting screw 36 and the smoothing frame 35. Its screw-nut pair structure facilitates the adjustment of the installation height of the sliding seat 34. The sliding seat is equipped with the rotating bracket 33 and a driving component 32 (either a drive motor or other driving component) that works with the rotating bracket 33. The driving component 32 drives the rotating bracket 33 to rotate and flip and smooth the tea leaves. The higher the adjustment height of the sliding seat 34, the higher the output thickness of the tea leaves after smoothing. This smoothing device can ensure the consistency of the tea leaf stack thickness at all parts of the conveyor belt, thereby making the tea leaves heat evenly. At the same time, the smoothing device also has a dispersing function, making the tea leaves fluffy and easier to heat.

[0032] In this embodiment, a temperature detection device 6 is also included, mounted on a 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.

The width guide rod assembly 61 is mounted on the length guide rod assembly 62 via a mounting base 63. The temperature detector 64 is mounted in conjunction with the width guide rod assembly 61 and its position can be adjusted along the width direction (either using a slide rail and slider or a screw and nut assembly, which is existing technology). The length guide rod assembly 62, in conjunction with the mounting base 63, can form a ball screw structure or use other structures (existing technology is acceptable here), allowing the temperature detector 64 to detect temperature not only along the length direction but also along the width direction.
