Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a roasting device for tobacco processing. Background Technology

[0002] In the tobacco processing flow, curing is a core step connecting tobacco leaf harvesting and subsequent processing. It involves the precise control of temperature, humidity, and time to physically dehydrate and biochemically transform fresh tobacco leaves, ultimately determining the quality, usability, and suitability for industrial processing.

[0003] In existing technologies, tobacco is typically placed on a mounting rod, which is then rotated by a drive mechanism to rotate and roast the tobacco. However, existing technologies generally use rigid components to pierce or clamp the tobacco. Because the tobacco stems are fragile and the leaves delicate, this rigid contact generates extreme local pressure at the point of contact, causing the stems to be pierced or crushed, creating mechanical wounds. During the subsequent roasting process, these wounds become channels for the abnormal and rapid loss of moisture and internal components, leading to premature drying and darkening of the color (commonly known as "roasting red" or "scalding"), resulting in significant quality defects. Furthermore, the physical damage is further exacerbated during the rotation of the device. In addition, the combined effect of centrifugal force and gravity causes continuous friction and tension between the fixed tobacco and the mounting rod, resulting in tearing and abrasion of the leaf tissue around the fixing point.

[0020] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0021] See Figures 1 to 5This embodiment discloses a roasting device for tobacco processing, including a roasting box body 1. The bottom of the roasting box body 1 is provided with four support legs 2, and the bottom of the support legs 2 is provided with rubber pads 3, which can provide support, shock absorption and anti-slip function. The internal cavity of the roasting box body 1 forms a roasting chamber 4, and the front side of the roasting box body 1 is provided with a door 5 that can be opened or closed. A drying drum 6 is rotatably installed inside the drying chamber 4. The drying drum 6 has multiple layers of tobacco placement trays 7 arranged at intervals. The tobacco placement trays 7 have a placement cavity 22 with an open top. The bottom wall of the placement cavity 22 is mesh-like. The placement cavity 22 is used to prevent tobacco that needs to be dried from getting wet. A partition plate 8 is detachably installed in the placement cavity 22 of the tobacco placement tray 7. The partition plate 8 divides the placement cavity 22 into several areas to facilitate the separate placement of tobacco of different specifications and varieties. A positioning element 9 is provided at the center of the bottom wall of the placement cavity 22 of the tobacco placement tray 7. The positioning element 9 has several positioning grooves 10 distributed circumferentially. The positioning grooves 10 extend radially along the placement cavity 22 and are used to fit into one end of the partition plate 8. The end of the partition plate 8 is magnetically attracted to the positioning groove 10 of the positioning component 9. When the partition plate 8 needs to be installed, one end of the partition plate 8 is inserted into the corresponding positioning groove 10, and it can be quickly attracted by magnetic attraction. When the partition plate 8 needs to be removed, the partition plate 8 can be pulled upward by force. The disassembly and assembly process is convenient and quick. Moreover, the number of partition plates 8 in each tobacco placement tray 7 can be adjusted as needed, thereby adjusting the size and number of the areas divided by them, so as to classify and roast tobacco of different sizes and types.

[0022] A loading / unloading port 11 is provided on one side of the baking drum 6. The loading / unloading port 11 can be closed or opened by a detachably connected sealing plate 12. The sealing plate 12 is provided with a handle 18, and there are fixing blocks 19 on the left and right sides of the sealing plate 12. A screw 20 passes through the through hole of the fixing block 19 and is screwed into the threaded hole 21 of the baking drum 6 to achieve detachable installation of the sealing plate 12 and the baking drum 6. Several through holes 13 are provided on the side wall of the baking drum 6 and on the sealing plate 12. The through holes 13 are strip-shaped holes that extend vertically along the baking drum 6.

[0023] A drive motor 14 is located at the bottom of the oven body 1. The output shaft of the drive motor 14 extends upward and is connected to the baking drum 6 via a rotating shaft, driving the baking drum 6 to rotate. A support base 15 is fixed to the bottom wall of the baking cavity 4 of the oven body 1. The rotating shaft is rotatably mounted on the support base 15. The bottom of the oven body 1 is detachably connected to the upper end of the rotating shaft, and the oven body 1 is located above the support base 15.

The steel balls 17 are rotatably mounted at the bottom of the retaining ring 16, and the bottom of the steel balls 17 protrudes downward from the bottom surface of the retaining ring 16. The top of the support base 15 has an annular groove that mates with the retaining ring 16. The retaining ring 16 rolls against the bottom wall of the annular groove of the support base 15 through the ring of steel balls 17 at its bottom. This structural design can provide rotational support for the oven body 1, ensuring its stability during rotation. At the same time, the rolling friction between the oven body 1 and the support base 15 during rotation can effectively reduce rotational friction.

[0024] The working process of the tobacco processing roasting device provided in this embodiment is as follows: In use, open the upper door 5 of the roasting oven body 1, lift the roasting drum 6 and remove it from the roasting oven body 1. Then, remove the sealing plate 12 from the roasting drum 6, place the tobacco to be roasted in the tobacco placement tray 7 inside the roasting drum 6, and then place the roasting drum 6 into the roasting cavity 4 of the roasting oven body 1, aligning it with the rotating shaft and support base 15. When drying the tobacco, start the drive motor 14. The rotation of the drive motor 14 will drive the rotating shaft to rotate, which in turn will drive the roasting drum 6 to rotate. The rotation of the roasting drum 6 will drive the tobacco placement tray 7 and the tobacco placed inside it to rotate. The hot air generated by the electric heating unit inside the roasting oven body 1 will enter the roasting drum 6 through the through hole 13 and rise to evenly roast the rotating tobacco. During roasting, it is not necessary to turn the tobacco or fix it, avoiding damage to the tobacco. The roasted tobacco has a natural shape and the roasting effect is good.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
