Description

Technical Field

[0001] This utility model belongs to the field of tea processing machinery technology, specifically relating to a drying device for enhancing the aroma of white tea. Background Technology

[0002] Tea aroma enhancement and drying is a technique that uses high temperatures to stimulate the aroma of tea leaves and remove moisture. The traditional aroma enhancement and drying process for white tea requires extremely high uniformity and precision in temperature control. Existing hot air drying equipment mainly uses convection for heat transfer, which suffers from uneven hot air distribution, poor temperature control precision, and low heat energy utilization, resulting in uneven drying of tea leaves and loss or incomplete transformation of aroma compounds. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a drying device for white tea aroma enhancement processing, which can improve the uniformity of white tea drying, drying effect and aroma of white tea.

A second bearing is provided at one end of the fixed shaft near the rear wall of the box body, and a roller is provided on the second bearing.

[0006] The housing is equipped with a drive motor, and the inner ring of the first bearing is equipped with a transmission shaft; one end of the transmission shaft is connected to the output shaft of the drive motor, and the other end is equipped with a gear.

[0007] A gear ring is provided at one end of the roller near the rear wall of the housing, and the gear ring meshes with a gear; a far-infrared radiation plate is provided on the fixed shaft; a sealing element is provided on the inner side of the door body through a third bearing, the sealing element is circular, and the sealing element can make close contact with the roller.

[0008] In the drying device for white tea aroma enhancement provided by this utility model, preferably, a plurality of tea lifting plates are arranged along the axial direction of the drum.

[0009] In the drying device for white tea aroma enhancement provided by this utility model, preferably, the drum has several holes.

[0010] In the drying device for white tea aroma enhancement provided by this utility model, more preferably, the far-infrared radiation plate is located at the lower end and the lower side end of the fixed shaft.

[0011] In the drying device for white tea aroma enhancement provided by this utility model, a reflective layer is further preferably provided on the inner wall of the drum.

[0012] In a further preferred embodiment of the drying device for white tea aroma enhancement provided by this utility model, a vacuum pump is provided on the box body, and the vacuum pump is connected to the interior of the box body through a pipe.

[0013] In the drying device for white tea aroma enhancement provided by this utility model, a buffer tank is further preferably provided on the pipeline.

[0014] In a further preferred embodiment of the drying device for white tea aroma enhancement provided by this utility model, a crushing disc is provided inside the box, and the crushing disc is located below the roller.

[0015] The above technical solution utilizes far-infrared radiation heating, where energy directly acts on the tea leaves, causing molecular resonance and heat generation within the leaves, thus expelling moisture. This ensures even heating and prevents the leaves from becoming burnt on the outside and damp on the inside. Furthermore, it effectively stimulates and transforms the aroma compounds in white tea, resulting in a superior aroma enhancement effect. A tea-lifting plate is installed inside the drum, allowing the tea leaves to be tumbled during rotation, ensuring even exposure to far-infrared radiation and improving heating uniformity. A reflective layer is incorporated within the drum to effectively utilize far-infrared radiation energy, increasing energy efficiency. A vacuum pump installed in the chamber maintains a slight vacuum during drying, enabling rapid drying while preserving the aroma of white tea. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] This embodiment provides a drying device for enhancing the aroma of white tea, such as... Figures 1 to 7 As shown, it includes a box body 1, a door body 2 hinged to the box body 1, a fixed shaft 3 and a first bearing 4 fixedly installed on the rear wall of the box body 1, a second bearing 5 installed at one end of the fixed shaft 3 near the rear wall of the box body 1, and a roller 6 installed on the second bearing 5.

[0026] A drive motor 7 is installed on the housing 1, and a transmission shaft 8 is installed on the inner ring of the first bearing 4; one end of the transmission shaft 8 is connected to the output shaft of the drive motor 7, and the other end is equipped with a gear 9.

[0027] A gear ring 10 is provided at one end of the roller 6 near the rear wall of the housing 1, which meshes with the gear 9; three far-infrared radiation plates 11 are provided on the fixed shaft 3; the far-infrared radiation plates 11 are located at the lower end and the lower side end of the fixed shaft 3.

[0028] A sealing element 13 is provided on the inner side of the door body 2 via a third bearing 12. The sealing element 13 is circular and can be in close contact with the roller 6. When the roller 6 rotates, the sealing element 13 rotates synchronously with the roller 6. The sealing element 13 is used to prevent tea leaves from falling from the front end of the roller 6 when the roller 6 rotates.

[0029] In order to lift the tea leaves during the rotation of the drum 6 and dry them evenly, 20 tea-lifting plates 14 are arranged inside the drum 6 along the axial direction of the drum 6.

[0030] In order to separate the broken tea produced during the drying process, several holes 15 are made on the drum 6. A broken material tray 20 is provided inside the box 1, which is located below the drum 6 and is used to catch the broken tea separated from the drum 6.

[0031] In order to effectively utilize the far-infrared rays emitted by the far-infrared radiation plate 11 and improve drying efficiency, a reflective layer 16 is provided on the inner wall of the drum 6, which can reflect the far-infrared rays irradiated on the reflective layer 16 onto the tea leaves.

[0032] A vacuum pump 17 is installed on the chamber 1, and the vacuum pump 17 is connected to the inside of the chamber 1 through a pipe 18. A buffer tank 19 is installed on the pipe 18. The vacuum pump 17 creates a micro-vacuum inside the chamber 1, which can quickly dry the moisture in the tea leaves, thereby improving the drying efficiency.

[0033] This invention is used as follows: Open door 2, place the tea leaves to be dried inside drum 6, close door 2, and the chamber 1 is sealed. The sealing element 13 is in tight contact with drum 6. Connect the power supply (drive motor 7, far-infrared radiation plate 11, and vacuum pump 17 are electrically connected to the power supply), start drive motor 7, far-infrared radiation plate 11, and vacuum pump 17. Drum 6 rotates under the drive of drive motor 7, and the tea leaves rotate accordingly. Under the action of tea lifting plate 14, the tea leaves can be lifted, achieving tumbling, so that all sides of the tea leaves can be irradiated by far-infrared rays, thus achieving uniform drying and ensuring drying efficiency and quality. The start of vacuum pump 17 creates a micro-vacuum state inside chamber 1, which can quickly dry the moisture from the tea leaves and discharge it outside chamber 1, improving drying efficiency. During the drying process, some broken tea leaves will be produced. These broken tea leaves can fall through holes 15 on drum 6 into the broken tea tray 20 below drum 6, achieving tea leaf separation. After drying, turn off the drive motor 7, far-infrared radiation plate 11 and vacuum pump 17. When the air pressure in chamber 1 returns to normal pressure, open the door 2 and take out the dried tea leaves.

[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.
