[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figure 1-3 As shown, a rosemary drying device is suitable for the pre-treatment drying of rosemary leaves or other herbs before essential oil extraction. It can achieve uniform hanging drying, improving drying efficiency and quality. It includes a box body 1, an air outlet duct 2, a hot air blower 3, a hanging frame 4, and clamps 5. Several hot air blowers 3 are connected to the two side walls along the length of the box body 1, and the air outlet duct 2 is connected to the top. The hanging frame 4 is fixed inside the box body 1. The clamps 5 for fixing rosemary are vertically suspended on the hanging frame 4.

[0025] It should be noted that the box 1 is used to place the clamps 5 containing rosemary to be dried; the box 1 is a sealed and insulated structure, with the inner wall lined with high-temperature resistant insulation material to reduce heat loss. The air outlet duct 2 is used to draw out water vapor, and an exhaust fan 10 can also be installed inside to increase the drying rate; the hot air fan 3 can provide a heat source for drying the rosemary; the hanging rack 4 facilitates the hanging of the clamps 5; the clamps 5 have a box-like structure, can hold a certain amount of rosemary and hang vertically, and are breathable to facilitate the contact between the hot airflow and the rosemary.

[0026] Specifically, the upper part of the enclosure 1 is constructed as an upward-contracting converging hood 6, while the lower part has a rectangular structure. This structure facilitates the upward convergence and smooth discharge of hot and humid airflow, preventing water vapor from condensing and dripping from the top of the enclosure. The lower part of the enclosure 1 has a rectangular structure with a regular internal space, which facilitates the rational arrangement of the hanging bracket 4 and clamps 5. Enclosure doors are also provided at both ends along the length of the enclosure 1.

[0027] Specifically, several sets of vertical rods 7 are provided below the suspension frame 4; a support rod 8 is fixedly connected to the lower end of each set of vertical rods 7; at least two hooks 9 are fixedly connected to the lower end of the support rod 8. The suspension frame 4 is fixed to the top of the inner side of the box 1 by a bracket. The hooks 9 are evenly distributed at the lower end of the support rod 8. In this application, nine sets of vertical rods 7 are provided below the suspension frame 4, and a horizontally arranged support rod 8 is fixedly connected to the lower end of each set of vertical rods 7; the support rod 8 is made of square steel pipe, and four evenly distributed hooks 9 are welded to its lower end. The hooks 9 are made of stainless steel with a smooth surface, which facilitates the hanging and removal of the clamp 5.

[0028] Specifically, the clamp 5 includes a horizontal round rod 51, a connecting rod 52, a square frame 53, a cover 54, and a mesh 55. Two connecting rods 52 are symmetrically fixed below the horizontal round rod 51. The connecting rods 52 are vertically fixed to one side of the square frame 53. The cover 54 matches the shape of the square frame 53 and is detachably connected to it. The square frame 53 is a frame structure. Mesh 55 is fixed to both the square frame 53 and the cover 54. The clamp 5 is made of stainless steel. The square frame 53 is welded from stainless steel strips and has a rectangular frame structure. The cover 54 matches the shape of the square frame 53, is connected to the square frame 53 on one side by a hinge, and has a latch locking mechanism on the other side to achieve quick opening and closing of the cover 54. Stainless steel mesh 55 is fixed to the inside of both the square frame 53 and the cover 54. The mesh 55 has a mesh size of 3-5 meshes, which can effectively support the rosemary branches and leaves without obstructing the passage of hot air.

[0029] Specifically, at least two layers of hot air blowers 3 are installed inside the chamber 1; the power of each layer of hot air blowers 3 gradually decreases from bottom to top. In this application, two layers of hot air blowers 3 are installed on both side walls of the chamber 1, with four hot air blowers 3 installed in each layer, evenly distributed along the length of the chamber. The power of the lower layer of hot air blowers 3 is 2.0-2.5kW, and the power of the upper layer of hot air blowers 3 is 1.5-2.0kW. Through this layered gradient power design, combined with the natural law of hot air rising, the vertical temperature gradient inside the chamber is compensated, achieving uniform drying.

[0030] This invention can also install a temperature sensor and a controller on the inner wall of the chamber 1, and a humidity sensor at the air outlet duct 2 to monitor changes in temperature and humidity inside the chamber. The controller can also be used to control the power of the hot air blower 3 and the air valve of the air outlet duct 2 in a coordinated manner to achieve intelligent management of the drying process.

[0031] The working principle of this utility model:

[0032] The operator opens the cover 54, evenly lays the rosemary plants on the mesh 55 of the square frame 53, closes the cover 54, and locks it with buckles. The clamps 5 are suspended from the hooks 9 via the horizontal rod 51, ensuring that the clamps 5 are spaced evenly. The hot air blower 3 is started, and hot air of different power levels is delivered in layers from both sides of the chamber, passing through the mesh 55 to evenly dry the rosemary. The hot and humid airflow is guided upwards by the confluence hood 6 and finally discharged through the exhaust duct 2. The drying parameters can be adjusted in real time through the monitoring system to achieve the best drying effect.

[0033] This application has a reasonable structure and is easy to operate. It is suitable for small and medium-sized rosemary drying processes and can also be extended to the pretreatment of other aromatic plants.

[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
