Description

Technical Field

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

[0002] Drying tea leaves is a crucial step in the tea production and processing process, playing a decisive role in the final aroma, taste, color, and shelf life of the tea.

[0003] In traditional tea drying processes, static or semi-static baking methods are used, where tea leaves are spread flat on a drying tray and heated. However, this method leads to uneven heating, with the bottom layer of tea leaves, being closer to the heat source, getting too hot, while the top layer gets too cold. To ensure drying quality, frequent manual turning is required, which not only increases labor intensity and reduces production efficiency, but also makes it difficult to guarantee the uniformity of manual operation, resulting in fluctuations in product quality between different batches and even within the same batch. In addition, tea stems and broken pieces inevitably occur during processing. In existing drying equipment, these impurities are mixed with the finished tea leaves and need to be separated by specialized screening equipment after the drying process, which undoubtedly increases the complexity of the production process and the investment cost of equipment.

[0004] To address these issues, some drying equipment integrating dynamic tumbling functions has emerged. For example, rotating drums are used to heat the tea leaves, and some designs employ mesh drums to remove impurities while drying. However, this structure introduces new technical challenges: tea stems and fragments sifted through the mesh fall directly to the heating area at the bottom of the equipment. As the equipment continues to operate, these impurities accumulate, severely blocking the flow of hot air and preventing it from reaching the tea leaves above. This leads to a significant decrease in drying efficiency and causes uneven heating again. Furthermore, the accumulated impurities make cleaning and maintenance extremely inconvenient and even pose safety hazards.

[0005] Therefore, this utility model proposes a tea production and processing equipment to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of uneven heating, low automation, and impurities generated during processing that clog hot air channels and are difficult to clean in the existing tea production and processing equipment, this utility model aims to provide a tea production and processing equipment with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a tea production and processing equipment, including: a box, a rotating mechanism, a heating mechanism; and a built-in rotating surface and a dustproof partition.

[0008] The built-in spiral surface is a plate-like structure that extends spirally along the inner wall of the mesh cylinder of the rotating mechanism; the dustproof partition is a pull-out plate-like structure.

[0009] Furthermore, the rotating mechanism is horizontally rotatably mounted on the upper middle part of the box, and the rotating mechanism includes a mesh tube for holding tea leaves therein for processing; The heating mechanism is installed at the bottom of the inside of the box and is used to generate hot air to dry the tea leaves in the mesh cylinder; The built-in spiral surface is fixedly connected to the inner wall of the mesh cylinder of the rotating mechanism. The built-in spiral surface extending along the axial direction of the mesh cylinder is fixedly connected to the inner wall of the mesh cylinder. The built-in spiral surface is used to push the tea leaves along the axial direction of the mesh cylinder from the feed end to the discharge end when the mesh cylinder rotates. The dustproof partition is slidably installed inside the housing and separates the rotating mechanism from the heating mechanism. It is used to receive and collect impurities that are screened out by the mesh of the screen cylinder, thereby ensuring that the hot air channel generated by the heating mechanism is unobstructed.

[0010] Preferably, the bottom of the dustproof partition has a mesh structure.

[0011] Preferably, the heating mechanism includes a heating pipe fixedly connected to the lower part of the housing, and fan blades for blowing air heated by the heating pipe upward.

[0012] Preferably, the heating mechanism further includes a fan frame, the fan blades are rotatably connected to the fan frame, and the fan frame is fixed to the inner bottom of the housing by patches and screws.

[0013] Preferably, the rotating mechanism further includes a rotating shaft and at least two sets of bearings. The rotating shaft is fixedly connected to the mesh cylinder via a connecting rod, and the rotating shaft is rotatably supported on the box body via the bearings.

[0014] Preferably, the bearing is fixedly connected to the inner wall of the housing via a connecting rod 2.

[0015] Preferably, the tea production and processing equipment further includes a feeding assembly fixedly connected to one side of the housing, the feeding assembly including a motor that provides rotational power, and the output shaft of the motor driving the rotation mechanism.

[0016] Preferably, the feeding assembly further includes a feeding port, the outlet of which is connected to the internal space of the mesh cylinder.

[0018] Preferably, the box body is also provided with a discharge port, which is located at the end of the mesh cylinder away from the inlet.

[0019] This utility model has the following beneficial effects: 1. This utility model solves the problems of low automation, low processing efficiency, and uneven heating of tea leaves in the prior art by setting an internal rotating surface inside the rotating mesh cylinder. It achieves the technical effect of automatically conveying tea leaves forward while drying them evenly, which significantly improves the level of automation, processing efficiency, and uniformity of product quality.

[0020] 2. This utility model solves the problem in the prior art where tea stems and debris generated during tea processing fall directly and block the hot air passage, contaminate the heating components, and cause a decrease in drying efficiency and difficulty in cleaning and maintenance by setting a pull-out dustproof partition between the rotating mechanism and the heating mechanism below. It achieves the technical effect of effectively separating and collecting impurities, preventing blockage of the hot air passage, ensuring the long-term stable drying efficiency of the equipment, and making the cleaning work simple and quick, thus improving the practicality and maintenance convenience of the equipment.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0024] Please refer to Figure 1 and Figure 2 A tea processing equipment includes a housing 1, which serves as the mounting carrier for the entire equipment and forms a closed working space. Inside the housing 1, from top to bottom, are a rotating mechanism 3, a dustproof partition 2, and a heating mechanism 4. The rotating mechanism 3 is horizontally rotatably mounted in the upper middle part of the housing 1. The dustproof partition 2 is slidably installed inside the housing 1 and separates the rotating mechanism 3 from the heating mechanism 4.

The feeding assembly 38 is used to feed tea into the rotating mechanism 3 and provide power to the rotating mechanism 3. The rotating mechanism 3 is used to tumble, screen, and convey the tea. The heating mechanism 4 is used to generate hot air to heat and dry the tea inside the rotating mechanism 3. Impurities generated during the tea processing fall into the dustproof partition 2 and are collected. The dried tea is finally discharged from the outlet 39.

[0025] Please refer to Figure 2 and Figure 3 The rotating mechanism 3 includes a mesh cylinder 31. An internal spiral surface 32, extending spirally along the axial direction of the mesh cylinder 31, is fixedly connected to the inner wall of the mesh cylinder 31. The function of the internal spiral surface 32 is to continuously push the tea leaves inside from the feeding end near the feeding component 38 to the discharge end near the discharge port 39 during the rotation of the mesh cylinder 31, thus achieving automatic forward movement of the tea leaves during processing. Simultaneously, the dustproof partition 2, as a flat structure with a handle, is slidably mounted on a guide rail on the inner wall of the housing 1 and is located within the rotating mechanism 3. Directly below and above the heating mechanism 4, the dustproof partition 2 has multiple mesh holes on its body, forming a structure with a mesh bottom.

By pulling out the dustproof partition 2, the collected impurities can be easily cleaned, avoiding the problem of impurity accumulation and blockage, and ensuring the long-term stability of the equipment.
