Description

Technical Field

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

[0002] Tea processing is a complex and meticulous process, involving multiple stages such as picking, withering, oxidation, pan-frying, rolling, and drying. Among these, charcoal roasting, as a crucial step in drying and aroma enhancement, has a vital impact on the quality of tea. Although the traditional charcoal roasting process has a long history, compared to electric roasting, it has better heat penetration, ensuring consistent heat distribution throughout the tea leaves and guaranteeing their final quality.

[0003] However, existing tea charcoal roasting processes often use roasting kilns or ovens with limited charcoal capacity. When long roasting times are required, the heat retention is often insufficient, necessitating the replacement of the kiln or oven, wasting manpower and time. For example, Wuyi rock tea is the most complex, time-consuming, and demanding type of tea in its charcoal roasting process, requiring careful attention to the specific characteristics of the tea leaves. Its core technique is "slow roasting over a gentle fire," aiming to thoroughly infuse the tea leaves with the heat, resulting in roasting times of dozens of hours or even more than ten days. Roasting kilns or ovens have limited charcoal capacity, effectively maintaining the roasting for a maximum of 36 hours, which is insufficient for long-term roasting needs.

[0004] Therefore, it is necessary to develop a charcoal roasting processing equipment to address the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a charcoal roasting equipment that can meet the needs of long-term tea roasting, avoids the need for manual repeated loading of the kiln or oven, and improves the efficiency of tea roasting.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to a charcoal roasting processing device, which includes a bottom support, a well ring body, and a tea roasting cage. The well ring body is a circular cement ring structure. Multiple well ring bodies are coaxially stacked above the charcoal loading cavity of the bottom support and the inner cavity can continue to stack charcoal upwards. The tea roasting cage for holding tea leaves is placed on the top surface of the top well ring body.

[0008] Furthermore, the bottom support is a tea roasting kang (heated brick bed), and the well ring body is stacked on top of the pit of the tea roasting kang.

[0009] The main body of the well ring is stacked on the pit of the tea roasting pit and applied directly to the pit. This allows for improvement without modifying existing tea roasting equipment, making it more flexible to use.

[0010] Furthermore, it also includes a reinforcing cage and handles. The reinforcing cage is a circular structure formed by bending and binding reinforcing bars and is embedded in the main body of the well ring. The four handles are symmetrically arranged on the outer wall of the main body of the well ring, and the base of the handles extends into the main body of the well ring and is welded to the reinforcing cage.

[0011] Furthermore, the reinforcing cage also includes an outlet joint, which extends horizontally outward from the reinforcing cage and is welded to the top wall of the handle; the handle and the outlet joint are provided in a one-to-one correspondence.

[0012] The addition of the handle facilitates the lifting and positioning of the well ring by tea roasting workers, which improves work efficiency, especially during the later ring removal operation.

[0013] Furthermore, the wall thickness of the well ring body is not less than 80 mm.

[0014] Furthermore, the bottom support is a tea roasting furnace, and the main body of the well ring is stacked above the charcoal charging chamber of the tea roasting furnace. A handle is provided on the outer iron wall of the tea roasting furnace.

[0015] When applied to existing tea roasting ovens, it allows for flexible placement compared to fixed tea roasting beds.

[0016] Furthermore, a ring boss is coaxially provided on the top surface of the well ring body, and a concave ring groove is coaxially provided on the bottom surface of the well ring body; the ring boss of the well ring body is embedded in the concave ring groove of the adjacent well ring body above.

[0017] The addition of an interlocking structure is an important improvement by the inventor, which overcomes the problem of misalignment during stacking, avoids tipping over after tilting, and makes the tea roasting process more stable.

[0018] Furthermore, the outer side of the well ring body is also covered with an insulation layer and an outer cylinder cover. The outer cylinder cover supports and supports the insulation layer and is fixedly welded to the handle.

[0019] Furthermore, the insulation layer is specifically formed by filling rock wool board or expanded perlite particles.

[0020] The tea roasting room requires prolonged heat preservation, resulting in energy consumption. However, by covering the outside of the well ring body with an insulation layer, the heat from the charcoal fire can be confined within the well ring body as much as possible, reducing heat loss into the room and significantly improving energy efficiency.

[0021] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0022] This utility model of smoldering charcoal roasting equipment, by adding multiple well rings stacked above the charcoal loading chamber of the bottom support, can continuously load charcoal upwards, increasing the amount of charcoal loaded and thus increasing the burning time, which can meet the needs of long-term tea roasting. Compared with the existing traditional charcoal roasting process, tea can be roasted for a long time with a single loading, avoiding repeated loading of the kiln or furnace, and reducing labor intensity.

[0023] Furthermore, by stacking the main body of the well ring onto the pit of the tea roasting kiln, it can be directly applied to traditional tea roasting facilities, reducing the renovation cost of the tea roasting room. Embedding a steel cage within the main body of the well ring increases its strength, reducing damage from collisions during use. Adding handles to the outer wall of the well ring facilitates lifting by workers. Welding the lead-out joints of the steel cage to the top wall of the handle increases its connection strength, preventing it from bending upwards and exposing its base inside the well ring. A well ring wall thickness is appropriately designed to increase its insulation performance and reduce heat loss. Combining the tea roasting kiln and the main body of the well ring makes the tea roasting process more spatially flexible, no longer confined to a specific tea roasting room. The kiln can be moved to the desired location and fitted with the well ring for tea roasting, making it more flexible in use. The addition of interlocking ring bosses and grooves between adjacent well ring bodies ensures alignment during stacking and a tight connection, preventing slippage. By adding an insulation layer and an outer cylinder cover, the insulation performance of the well ring body can be further increased, reducing heat loss and saving charcoal consumption; the outer cylinder cover supports and holds the rock wool board or expanded perlite particles, preventing the insulation material from loosening and falling off.

[0031] The core of this utility model is to provide a charcoal roasting processing equipment that can meet the needs of long-term tea roasting, avoid the need for manual repeated loading of the kiln or oven, and improve the efficiency of tea roasting.

[0035] Example 1

[0036] like Figures 1-3 As shown, the charcoal roasting equipment of this utility model includes a bottom support, a well ring body 1, and a tea roasting cage 7. The well ring body 1 is a circular cement ring structure, cast using a mold. Multiple well ring bodies 1 are coaxially stacked above the charcoal loading cavity of the bottom support, and their cylindrical inner cavity can continue to stack charcoal upwards, thereby increasing the charcoal loading capacity. The tea roasting cage 7, used to hold tea leaves, is placed on the top surface of the top well ring body 1.

[0037] By adding multiple well ring bodies 1 stacked above the charcoal loading chamber of the bottom support, charcoal can be continuously loaded upwards, increasing the amount of charcoal loaded and thus increasing the burning time, which can meet the needs of long-term tea roasting. Compared with the existing traditional charcoal roasting process, tea can be roasted for a long time with a single loading, avoiding repeated loading of the kiln or furnace, and reducing labor intensity.

[0038] Specifically, such as Figure 1 As shown, the bottom support is a tea roasting kiln 6, and a well ring body 1 is stacked on top of the kiln pit of the tea roasting kiln 6. The tea roasting kiln 6 has multiple kiln pits, and multiple well ring bodies 1 can be stacked on each kiln pit.

[0039] By stacking the main body 1 of the well ring onto the pit of the tea roasting kang 6, it can be directly applied to traditional tea roasting facilities, reducing the renovation cost of the tea roasting room.

[0040] In one specific implementation of this embodiment, such as Figures 1-3 As shown, the charcoal roasting equipment of this utility model also includes a reinforcing cage 2 and handles 3. The reinforcing cage 2 is a circular structure formed by bending and binding reinforcing bars and is embedded in the well ring body 1, which is cast in concrete. Four handles 3 are symmetrically arranged on the outer wall of the well ring body 1, with two parallel handles 3 forming a group, and two groups of handles 3 arranged symmetrically. The root of the handle 3 extends into the well ring body 1 and is welded to the reinforcing cage 2.

[0041] Obviously, the handle 3 can also be replaced by a groove formed on the outer wall of the well ring body 1, and the well ring body 1 can be lifted by using the handle groove. Similar simple modifications all fall within the protection scope of this utility model.

[0042] Specifically, such as Figures 1-3 As shown, the reinforcing cage 2 also includes a lead-out connector 201, which extends horizontally outward from the reinforcing cage 2 and is welded to the top wall of the handle 3. The handle 3 and the lead-out connector 201 are arranged in a one-to-one correspondence. The handle 3 is formed of steel pipe.

[0043] Specifically, such as Figures 1-3 As shown, the wall thickness of the well ring body 1 is not less than 80 mm.

[0044] By embedding a steel cage 2 within the main body 1 of the well ring, the strength of the main body 1 is improved, reducing the risk of damage from collisions during use. Adding a handle 3 to the outer wall of the main body 1 facilitates lifting by workers. Welding the lead-out joint 201 of the steel cage 2 to the top wall of the handle 3 increases the connection strength of the handle 3, preventing it from bending upwards and exposing its root inside the main body 1. A properly designed wall thickness for the main body 1 increases its thermal insulation performance and reduces heat loss.

[0045] The operation of this utility model of smoldering charcoal roasting equipment is as follows: First, charcoal is loaded into the pit of the tea roasting pit 6, and then crushed and compacted using a sledgehammer. Next, the first layer of the well ring body 1 is placed, and more charcoal is added, crushed, and compacted again. The second layer of the well ring body 1 is then lifted, and so on, layer by layer, adding charcoal and compacting each layer. This process of adding rings, charcoal, and hammering is repeated 9 times in 8 layers, resulting in a 1.2-meter-high well tower with a total charcoal loading of approximately 400 catties. Then, the top layer of charcoal is ignited, covered with charcoal ash, and the tea is roasted using smoldering fire. The tea roasting basket 7, filled with tea leaves, is placed on top of the top well ring body 1, and roasting begins. Approximately every 24 hours, one well ring is removed, and the ash thickness is readjusted to maintain a height of about 15 cm between the tea and the charcoal pile on the roasting basket 7. This tea roasting equipment can burn continuously for more than ten days without needing to repeatedly load and unload the pit, significantly improving the efficiency of tea roasting operations compared to traditional tea roasting pits.

[0046] Example 2

[0047] Based on the above embodiment 1, this embodiment is formed by improving the application of this utility model.

[0048] like Figure 4 As shown, the bottom support is a tea roasting stove 8. The main body 1 of the well ring is stacked above the charcoal loading chamber of the tea roasting stove 8, and a handle 801 is provided on the outer iron wall of the tea roasting stove 8. The tea roasting stove 8 is used independently and is more flexible in use compared to the tea roasting kiln 6.

[0049] The combination of the tea roasting stove 8 and the well ring body 1 makes the tea roasting process more flexible in terms of space. It is not necessary to be confined to a specific tea roasting room. The tea roasting stove 8 can be moved to the place of use as needed and put into the well ring body 1 to roast tea, making it more flexible in use.

[0050] Example 3

[0051] In the above embodiment 1 or embodiment 2, since the height of the well ring body 1 is 15 cm, the height increases after multiple stacks, which may lead to instability and misalignment. Therefore, improvements are needed to form this embodiment.

[0052] like Figure 5 As shown, a ring boss 101 is coaxially provided on the top surface of the well ring body 1, and a concave ring groove 102 is coaxially provided on the bottom surface of the well ring body 1. The ring boss 101 of the well ring body 1 is embedded in the concave ring groove 102 of the adjacent well ring body 1 above.

[0053] By adding interlocking annular protrusions 101 and concave annular grooves 102 to the adjacent well ring bodies 1, the centering during the stacking process is ensured, and the connection between them is tight, thus preventing slippage.

[0054] In one specific implementation of this embodiment, such as Figure 4 As shown, the outer side of the well ring body 1 is also covered with an insulation layer 4 and an outer cylinder cover 5. The outer cylinder cover 5 supports and supports the insulation layer 4. The top and bottom edges of the outer cylinder cover 5 are provided with inward folded edges. The outer cylinder cover 5 is connected by a fixed welding method at the position where it passes through the handle 3.

[0055] Specifically, such as Figure 4 As shown, insulation layer 4 is specifically formed by filling with rock wool board or expanded perlite granules. Rock wool board or expanded perlite granules have high high-temperature resistance and are suitable for thermal insulation under high-temperature conditions.

[0056] By adding an insulation layer 4 and an outer cylinder cover 5, the insulation performance of the well ring body 1 can be further increased, the heat loss to the outside can be reduced, and the amount of charcoal used can be saved; the outer cylinder cover 5 supports and holds the rock wool board or expanded perlite particles, preventing the insulation material from loosening and falling off.

[0057] In summary, this utility model of smoldering charcoal roasting equipment, by adding multiple well ring bodies 1 stacked above the charcoal loading chamber of the bottom support, allows for continuous upward charcoal loading, increasing the charcoal capacity and thus the burning time, meeting the needs of long-term tea roasting. Compared to existing traditional charcoal roasting processes, a single loading allows for long-term tea roasting, avoiding repeated loading of the roasting pit or furnace, and reducing labor intensity. Furthermore, by stacking the well ring bodies 1 on the roasting pit of the tea roasting pit 6, it can be directly applied to traditional tea roasting facilities, reducing the renovation cost of the tea roasting room. Embedding a steel cage 2 within the well ring body 1 increases its strength, reducing damage from collisions during use. Adding a handle 3 to the outer wall of the well ring body 1 facilitates lifting by operators. Welding the lead-out joint 201 of the steel cage 2 to the top wall of the handle 3 increases the connection strength of the handle 3, preventing it from bending upwards and exposing its root from the well ring body 1. Reasonably setting the wall thickness of the well ring body 1 increases its heat insulation performance, reducing heat loss. The combination of the tea roasting stove 8 and the well ring body 1 makes the tea roasting process more spatially flexible, no longer confined to a specific tea roasting room. The tea roasting stove 8 can be moved to the desired location and fitted with the well ring body 1 for tea roasting, making it more flexible in use. The addition of interlocking ring bosses 101 and concave ring grooves 102 between adjacent well ring bodies 1 ensures alignment during stacking and a tight connection, preventing slippage. The addition of an insulation layer 4 and an outer cylinder cover 5 further enhances the insulation performance of the well ring body 1, reducing heat loss and saving charcoal. The outer cylinder cover 5 supports and holds the rock wool board or expanded perlite granules, preventing the insulation material from loosening and falling off.
