Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a tea baking and aroma-enhancing machine for evenly drying tea. Background Art

[0002] Tea, commonly known as tea, generally consists of the leaves and buds of the Camellia sinensis plant. Tea beverages made from tea leaves are one of the world's three major beverages. Tea processing primarily involves the following steps: picking, withering, cooling, and roasting. Roasting, in particular, evaporates excess moisture from the tea leaves, reducing their moisture content to 3%-5%. This roasted tea has a unique flavor and rich aroma, while also promoting its preservation. In the prior art, a rotary tea roasting and aroma-enhancing machine is mainly used to roast tea. The principle is to set a heat source on the side wall of the machine box, and set multiple trays on a rotating central axis. The tea leaves are placed on the trays and dried while rotating and being heated. For example, the Chinese utility model patent with publication number CN211575760U discloses a rose tea drying device, which dries the tea leaves placed on a fixed tray by setting a spiral heating tube on the inner wall of the drying box and a circulating fan at the bottom. However, this structure has certain problems. Since the heat source is on the side wall, the tea leaves placed on the outer side of the fixed tray are closer to the heat source than the tea leaves in the center. Therefore, the tea leaves on the outer side of the fixed tray will dry faster, which will eventually lead to uneven drying of the tea leaves as a whole. Utility Model Content

[0019] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1-5 The embodiment shown provides a tea roasting and aroma-enhancing machine for uniform drying, including a box body 1, which provides installation space for other parts. A box door 2 is hinged on one side of the box body 1 in the horizontal direction. When tea needs to be put into the box body 1, the box door 2 is opened and put in. When the tea leaves are dried, the box door 2 is closed. A driving motor 7 is provided on the top of the box body 1, and a rotating shaft 3 is vertically provided inside the box body 1. The output end of the driving motor 7 passes through the top side wall of the box body 1 and is connected to the rotating shaft 3. The driving motor 7 is configured to drive the rotating shaft 3 to rotate. A plurality of racks 4 are arranged at intervals on the rotating shaft 3, and tea leaves to be dried are placed on the racks 4. A drying device 5 is provided on both sides of each rack 4 in the horizontal direction of the box body 1, and the drying device 5 generates hot air to dry the tea leaves. The air outlet plate 54 of the drying device 5 is located above the rack 4, and the hot air generated by the drying device 5 is discharged downward from the air outlet plate 54. A support rod 6 is provided at the bottom of the box body 1 for supporting the box body 1.

[0022] The working principle and usage process of this embodiment are as follows:

[0023] When the present invention is in use, tea leaves are loaded into the box body 1 by opening the box door 2, and the tea leaves are placed on the rack 4. The box door 2 is then closed, and the drying device 5 is started to dry the tea leaves in the box body 1. At the same time, the drive motor 7 is started to rotate the rotating shaft 3, and the rack 4 rotates along with the rotating shaft 3, so that the tea leaves continuously pass through the air outlet plate 54 of the drying device 5 during the rotation process. Since the air outlet plate 54 of the drying device 5 is arranged above the rack 4, the distance between the tea leaves on the rack 4 and the heat source is the same, and the drying effect is the same, thereby achieving a uniform drying effect. A drying device 5 is provided on each side of the rack 4 to prevent the tea leaves from being heated for too short a time during the rotation process, thereby preventing the tea leaves from being dried poorly.

[0024] Example 2

[0025] This embodiment is developed based on the above embodiment to solve the installation stability of the rack 4. Figure 2As shown, specifically, a number of supporting assemblies are arranged at intervals on the rotating shaft 3, and a shelf 4 is provided on each supporting assembly. The supporting assembly below the shelf 4 provides supporting force to the shelf 4, and the supporting assembly includes at least four supporting rods 8 arranged in the circumferential direction of the rotating shaft 3. The four supporting rods 8 provide the most stable supporting force to the shelf 4.

[0026] Example 3

[0027] This embodiment is developed on the basis of the above embodiment. Specifically, this embodiment discloses the specific structure of the drying device 5, such as Figure 3-4 As shown, the drying device 5 also includes a fan 51, an electric heating element 52 and a deflector 53. The fan 51 and the electric heating element 52 are arranged on the side wall of the box body 1. The air inlet of the fan 51 is close to the outside of the box body 1, and the electric heating element 52 is located at the air outlet of the fan 51. The wind generated by the fan 51 is heated by the electric heating element 52 and blown out from the air outlet to become hot air. It should be noted that the present application does not limit the specific structure and form of the electric heating element 52. It only needs to be able to heat after being powered on, such as an electric heating wire. The present application does not go into details about this. The deflector 53 covers the air outlet of the fan 51 to prevent the heated hot air from leaking out. The air outlet plate 54 is connected to the deflector 53 and is located above the storage rack 4. The length of the air outlet plate 54 covers one side edge of the storage rack 4 to the edge of the rotating shaft 3. The hot air blown out by the fan 51 is guided by the deflector 53 and blown out from the air outlet plate 54.

[0028] Furthermore, if Figure 3-4 As shown, a plurality of ventilation holes 9 are provided on the air outlet plate 54. The diameter of the ventilation holes 9 is 2 mm. By providing the ventilation holes 9 on the air outlet plate 54 to discharge hot air, the drying effect of the tea leaves can be improved and the drying time of the tea leaves can be reduced.

[0029] Example 4

[0030] This embodiment is developed based on the above embodiment to prevent tea leaves from being thrown away during the rotation process. Specifically, Figure 1 、 5 As shown, the rack 4 is circular and its edges are folded upwards, and the folded portion can prevent the tea leaves from being thrown out of the rack 4. It should be noted that the bottom of the rack 4 can also be set as a ventilation structure. This arrangement avoids the bottom of the rack 4 being solid, and the wind from the drying device 5 flows to both sides, thereby blowing the tea leaves on the rack 4 everywhere.

[0031] Furthermore, if Figure 5 As shown, the shelf 4 is composed of two semicircular plates assembled by a magnetic element 10, which makes it easy to remove the shelf 4 from the rotating shaft 3 to place tea leaves.

[0032] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
