Description

Technical Field

[0001] This utility model belongs to the field of tea production technology, and in particular relates to a tea drying machine. Background Technology

[0002] Drying is an important step in tea production. Its main purpose is to remove the moisture from the tea leaves, while also shaping the leaves and making them more resistant to oxidation. A good drying process helps ensure the quality of the tea.

[0003] In the existing technology, when tea leaves are directly put into a dryer with a high drying temperature, the surface temperature of the tea leaves may rise rapidly, causing the surface moisture to evaporate quickly, while the internal moisture does not have time to diffuse to the surface. This results in uneven drying inside and outside the leaves, which can easily lead to cracks or breakage of the leaves, affecting the overall structure and appearance of the tea.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 As shown, Figure 1 The diagram shown is a front view of the tea drying machine in the embodiment.

[0025] This device includes:

[0026] Drying box 10, the drying box 10 includes a feed inlet 11 located at the top;

[0027] The conveyor belt is installed inside the drying chamber 10. The conveyor belt includes conveyor belt 1 21, conveyor belt 22 and conveyor belt 3 23 arranged sequentially from top to bottom. The starting end of conveyor belt 1 21 is located below the feed inlet 11. The starting end of conveyor belt 22 is connected to the end of conveyor belt 1 21. The starting end of conveyor belt 3 23 is connected to the end of conveyor belt 2 22.

[0028] The heating element includes heating element 1 31, heating element 2 32 and heating element 33 disposed on the side wall of the drying chamber 10. Heating element 1 31, heating element 2 32 and heating element 33 are respectively disposed above conveyor belt 1 21, conveyor belt 22 and conveyor belt 3 23, and the output temperature of heating element 1 31, heating element 2 32 and heating element 33 increases sequentially.

[0029] The drying box 10 also includes a discharge port 12, and the end of the conveyor belt 23 is connected to the top of the discharge port 12.

[0030] The feed inlet 11 is used to feed the tea leaves to be dried into the drying box 10. The first conveyor belt 21 starts below the feed inlet 11, receives the tea leaves entering from the feed inlet 11, and conveys them forward to its end. Then the tea leaves are transferred from the end of the first conveyor belt 21 to the second conveyor belt 22 connected to it, and continue to be conveyed in the opposite direction. Finally, the tea leaves reach the position above the discharge outlet 12 through the third conveyor belt 23 and are discharged from the discharge outlet 12.

[0031] Specifically, conveyor belt 22 has the opposite transmission direction to conveyor belt 21, and conveyor belt 23 has the opposite transmission direction to conveyor belt 22. The transmission directions of conveyor belt 21, conveyor belt 22, and conveyor belt 23 are as follows: Figure 1 As indicated by the middle arrow, the structures of each conveyor belt, drive shaft, etc., are existing technologies and will not be described in detail here.

[0032] Heating element 1 (31), heating element 2 (32), and heating element 3 (33) are respectively positioned above the corresponding conveyor belts, and their output temperatures increase sequentially. This allows the tea leaves to complete the entire drying process in a gradually warming environment.

[0033] By gradually increasing the temperature, tea leaves can be protected from damage caused by sudden exposure to high temperatures. This helps preserve the active ingredients and aroma compounds in the tea leaves, ensuring their quality.

[0034] Different temperature settings allow the tea leaves to effectively expel moisture at each stage. Initial drying at lower temperatures helps initiate the dehydration process, while gradually increasing temperatures accelerate this process, ensuring that the tea leaves are dried evenly and thoroughly.

[0035] Specifically, heating element 1 31, heating element 2 32 and heating element 3 33 are heating elements, which can be heating wires, heating tubes, etc.

[0036] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a front view of the tea drying machine in the embodiment. Figure 2 The diagram shown is a schematic representation of the cost-sharing component in the embodiment;

[0037] It also includes a spreading component 40, which is set on the inner top wall of the drying box 10. The spreading component 40 includes a number of evenly distributed spreading rods 43 at intervals. The spreading rods 43 are located above the conveyor belt 21 and spread the tea leaves on the conveyor belt 21.

[0038] The arrangement of several distribution rods 43 ensures that they can effectively act on the tea leaves that have just fallen from the feed inlet 11 onto the conveyor belt 21, dispersing these piled-up or clustered tea leaves. By dispersing the tea leaves, the surface area of ​​the tea leaves in contact with the hot air is increased, which helps to improve the drying efficiency, ensures that the tea leaves are more evenly distributed throughout the conveying process, avoids local overheating or underheating, and is conducive to achieving a more uniform tea drying effect.

[0039] The distribution component 40 includes a fixed frame 41, the top of which is fixedly connected to the inner top wall of the drying oven 10, and a fixed block 42 is provided at the bottom of the fixed frame 41. Several distribution rods 43 are detachably provided at the bottom of the fixed block 42.

[0040] The fixing block 42 is provided with a plurality of insertion holes 421 for the distribution rod 43 to be inserted, and the upper end of the distribution rod 43 is threaded into the insertion hole 421.

[0041] Specifically, the spreading rod 43 is cylindrical, and the insertion hole 421 is a hole that matches its shape. The fixing bracket 41 and the fixing block 42 support and fix several spreading rods 43. The insertion hole 421 on the fixing block 42 not only plays a positioning role, but also forms a firm connection with the spreading rod 43 through the thread design. This design makes it easy to install and disassemble the spreading rod 43, and facilitates cleaning, maintenance or replacement. In addition, according to different production needs (such as the type of tea, batch size, etc.), the spreading effect can be optimized by increasing or decreasing the number of spreading rods 43 or adjusting the spacing between them.

[0042] like Figure 3 As shown, Figure 3 The diagram shown is a structural schematic of the sharing rod in the embodiment;

[0043] The distribution pole 43 includes a pole body 431 and a protective sleeve 432 disposed on the outside of the pole body 431. The protective sleeve 432 is made of flexible material.

[0044] The flexible protective sleeve 432 reduces physical damage to the tea leaves. During the spreading process, using hard materials directly could scratch or break the tea leaves, while the flexible material effectively prevents this, ensuring the integrity of the tea leaves. The flexible protective sleeve 432 can also adaptively adjust its contact surface shape according to the stacking of the tea leaves, better conforming to the surface and thus more effectively dispersing them.

[0045] The flexible protective sleeve 432 can be made of silicone, which has good heat resistance and flexibility, and can maintain stable performance over a wide temperature range. In addition, silicone has excellent food contact safety and is easy to clean.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
