Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a fixation device for tea processing. Background Technology

[0002] In tea processing, fixation (or killing the green) is a crucial step, directly impacting the quality of the tea. Proper fixation can deactivate enzymes in the tea leaves, preventing fermentation and preserving the color, aroma, and nutrients. However, existing fixation devices for tea processing have many shortcomings.

[0003] Traditional withering equipment typically relies solely on the heating of the roasting chamber itself. This single heat source model easily leads to insufficient or uneven heat supply. In practice, due to variations in the distance and contact method between different locations within the roasting chamber and the heating source, the degree of heating of the tea leaves varies significantly during the withering process. Some tea leaves may become scorched due to overheating, losing their original flavor and quality; while other tea leaves may not be thoroughly withered, and enzyme activity may not be effectively inhibited, making them prone to spoilage during subsequent storage and processing, seriously affecting the overall stability and consistency of the tea's quality.

[0004] Therefore, how to solve the problem of uneven heat supply leading to poor fixation effect in tea fixing is a problem that needs to be solved. Utility Model Content

[0005] In view of this, the present invention provides a fixation device for tea processing, which provides an additional heat source to the fixation mechanism through an auxiliary heating mechanism, so as to avoid poor fixation effect caused by uneven heating when fixing tea.

[0006] To address the aforementioned technical problems, this utility model provides a fixation device for tea processing, comprising a fixation mechanism, which includes a roasting chamber. An auxiliary heating mechanism is connected to one side of the fixation mechanism. The auxiliary heating mechanism includes a heating box with a partition inside, and a heat dissipation assembly inside. The heat dissipation assembly includes a secondary water tank located on one side of the partition, and several heat dissipation copper pipes connected between the partition and the secondary water tank. A fan for guiding hot air into the roasting chamber is located below the heat dissipation copper pipes. By providing an auxiliary heating mechanism to the roasting chamber and utilizing the heat dissipation assembly to generate hot air, the device provides additional heat to the roasting chamber, ensuring even heating of the tea leaves during the fixation process and improving the fixation effect.

[0007] The auxiliary heating mechanism also includes a heating component that provides a heat source for the heat dissipation copper pipes. This component includes a hot water tank located on one side of the heating chamber and a first water pump located on top of the hot water tank. The combined use of the first water pump and the hot water tank ensures a stable water supply to the heat dissipation copper pipes, guaranteeing a continuous and stable heat source. This, in turn, stabilizes the temperature of the hot air introduced into the roasting chamber by the fan, helping to improve the temperature stability during the tea processing and thus enhancing the quality of the roasting process.

[0008] A water pump is connected to the hot water tank via a suction pipe, and a water supply pipe is connected to the outlet of the first water pump. The water supply pipe is located inside the heating tank and has several connecting pipes, each of which is connected to the inlet of a heat dissipation copper pipe. By connecting the connecting pipes to the heat dissipation copper pipes and sending hot water into the heat dissipation copper pipes via the first water pump, the hot water can be accurately and smoothly delivered from the hot water tank to the heat dissipation copper pipes. This ensures that the heat dissipation copper pipes can fully absorb the heat from the hot water, thereby making the temperature and heat distribution of the hot air generated by the fan more uniform, which is beneficial to improving the uniformity of tea leaf processing.

[0009] A return flow assembly is connected to the partition to guide water from the auxiliary water tank back to the hot water tank. The return flow assembly includes a second water pump installed on the side wall of the partition. A suction pipe connects the pump's pumping end to the auxiliary water tank, and a return pipe connects the pump to the hot water tank. The auxiliary water tank receives water flowing in through the heat dissipation copper pipes, and the return flow assembly guides the water back to the hot water tank, achieving water recycling, reducing water waste, and maintaining water circulation throughout the heating system. This ensures the continuity and stability of the heating and heat dissipation components, providing stability for the blanching device.

[0010] The auxiliary heating mechanism is connected to the roasting chamber via an exhaust duct. This connection allows the hot air generated by the auxiliary heating mechanism to be effectively delivered to the roasting chamber, providing additional heat for the tea leaves during the roasting process, ensuring smooth heat transfer, and helping to improve roasting efficiency.

[0011] Inside the roasting chamber, a rake is rotated to turn the tea leaves, and a geared motor is connected to the outer wall of the chamber to drive the rake to rotate. By driving the rake to rotate, the tea leaves inside the roasting chamber are continuously turned, ensuring that all parts of the tea leaves are heated evenly during the fixation process. This avoids localized overheating or underheating, greatly improving the uniformity and quality of the fixation process.

[0012] The output shaft of the geared motor is connected to a rotating shaft via a coupling. One end of the rotating shaft is connected to the inner wall of the roasting chamber via a bearing. In other words, the geared motor's output shaft is connected to the rotating shaft via a coupling, and one end of the rotating shaft is connected to the inner wall of the roasting chamber via a bearing. The geared motor drives the rake to rotate. This connection structure ensures that the power of the geared motor can be stably and reliably transmitted to the rake, allowing the rake to rotate smoothly and continuously, thus more effectively turning the tea leaves and providing stable mechanical power support for the uniform processing of the tea leaves.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. The auxiliary heating mechanism provides additional heat to the roasting chamber of the fixation mechanism. The heating component delivers hot water to the heat dissipation copper pipe through the hot water tank and the first water pump. The heat dissipation component uses a fan to guide the hot air emitted by the heat dissipation copper pipe into the roasting chamber, which can increase the temperature during the fixation process and improve the efficiency and quality of tea fixation.

[0015] 2. The design of the reflux assembly enables the recycling of water resources. A second water pump draws water from the auxiliary water tank through a suction pipe, then returns it to the hot water tank via a reflux pipe, reducing water waste and lowering the cost of tea processing.

[0016] 3. The auxiliary heating mechanism is connected to the frying chamber through an air duct, which ensures that the hot air generated by the heat dissipation components is accurately introduced into the frying chamber, so that the heat is concentrated on the tea leaves, effectively preventing heat loss and improving energy utilization.

[0017] 4. The rotating rake inside the roasting chamber, driven by a geared motor, turns the tea leaves. This turning ensures more even heating of the tea leaves during the fixation process, guaranteeing consistent fixation results and improving tea quality. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-6 As shown: This embodiment provides a fixation device for tea processing, including a fixation mechanism 1. An auxiliary heating mechanism 2 is connected to one side of the fixation mechanism 1. The fixation mechanism 1 also includes the auxiliary heating mechanism 2, which includes a heating box 21. The heating box 21 is provided with a partition 22 and a heat dissipation component 23 inside. The heat dissipation component 23 includes a secondary water tank 231 located on one side of the partition 22. Several heat dissipation copper pipes 232 are connected between the partition 22 and the secondary water tank 231. A fan 233 for introducing hot air into the frying chamber 11 is provided below the heat dissipation copper pipes 232. By installing an auxiliary heating mechanism 2 on one side of the fixing mechanism 1, the fan 233 in the auxiliary heating mechanism 2 introduces the hot air emitted by the heat dissipation copper pipe 232 into the frying chamber 11, thereby providing hot air auxiliary heating to the frying chamber 11 and improving the fixing effect of tea. That is, by setting the auxiliary heating mechanism 2, additional hot air auxiliary heating can be provided to the frying chamber 11 in the fixing mechanism 1, improving the fixing effect. Moreover, the heat dissipation component 23 can effectively realize the transfer and distribution of heat. In addition, an air inlet is opened at the bottom of the heating box 21, so that the external air source enters the heating box 21 under the action of the fan 233. At the same time, a filter screen for filtering air is installed at the air inlet to prevent impurities in the air from entering the frying chamber 11 and affecting the fixing effect.

[0027] The auxiliary heating mechanism 2 also includes a heating component 24 that provides a heat source for the heat dissipation copper pipe 232. The heating component 24 includes a hot water tank 241 located on one side of the heating box 21, and a first water pump 242 located on top of the hot water tank 241. The hot water tank 241 stores hot water and heats the water source. Then, the first water pump 242 draws the hot water from the hot water tank 241 and enters the first water pump 242 through the water extraction pipe 243. The first water pump 242 then delivers the hot water to the heating box 21 through the water supply pipe 244. The connecting pipe 245 on the water supply pipe 244 is connected to the inlet of the heat dissipation copper pipe 232, providing a stable hot water heat source for the heat dissipation copper pipe 232, ensuring a stable hot air temperature, guaranteeing the temperature and stability of the hot air, and thus improving the quality and stability of the blanching process.

[0028] A water pump 242 is connected to the hot water tank 241 via a water pump 243. A water supply pipe 244 is connected to the outlet of the first water pump 242 and is located inside the heating chamber 21. Several connecting pipes 245 are attached to the water supply pipe 244, each connecting pipe 245 connecting to the inlet of each heat dissipation copper pipe 232. This connection method ensures that hot water is evenly and effectively distributed to each heat dissipation copper pipe 232, resulting in a more uniform temperature distribution of the hot air and improving the uniformity of tea leaf processing.

[0029] A return flow assembly 25 is connected to the partition 22 for guiding water from the auxiliary water tank 231 back to the hot water tank 241. The return flow assembly 25 includes a second water pump 251 installed on the side wall of the partition 22. A suction pipe 252 is connected between the suction end of the second water pump 251 and the auxiliary water tank 231, and a return flow pipe 253 is connected between the second water pump 251 and the hot water tank 241. The second water pump 251 draws water that has absorbed heat from the auxiliary water tank 231 through the suction pipe 252 and sends it back to the hot water tank 241 through the return flow pipe 253, realizing the recycling of water resources, reducing energy consumption, and maintaining the thermal balance of the system. That is, by guiding the water that has dissipated heat from the auxiliary water tank 231 back to the hot water tank 241 through the return flow assembly 25, the recycling of water resources is realized, energy consumption is reduced, and the thermal balance of the entire system is maintained.

[0030] The auxiliary heating mechanism 2 is connected to the roasting chamber 11 via an exhaust pipe 26. This connection allows the hot air generated by the auxiliary heating mechanism 2 to be directly delivered to the roasting chamber 11 through the exhaust pipe 26 under the influence of the fan 233, providing the necessary heat for the tea's processing and ensuring the smooth participation of the hot air in the tea's processing.

[0031] A rake 12 for turning the tea leaves is rotatably installed inside the roasting chamber 11, and a geared motor 14 for driving the rake 12 to rotate is connected to the outer wall of the roasting chamber 11. When the geared motor 14 is working, its output shaft drives the rake 12 to rotate, and the tea leaves are continuously turned over during the fixation process, ensuring that the tea leaves are heated evenly and improving the fixation quality.

[0032] The output shaft of the geared motor 14 is connected to a rotating shaft 13 via a coupling. One end of the rotating shaft 13 is connected to the inner wall of the roasting chamber 11 via a bearing. The coupling ensures the effective transmission of power between the geared motor 14 and the rotating shaft 13, while the bearing supports the rotating shaft 13, enabling it to rotate stably. This, in turn, ensures the stable rotation of the rake 12, ensuring stable tea leaf turning and improving the stability of the withering effect.

[0033] The method of using this utility model is as follows: First, inject an appropriate amount of water into the hot water tank 241 and heat the water through the water heater on the hot water tank 241. Then, turn on the first water pump 242. The first water pump 242 draws water from the hot water tank 241 through the water pumping pipe 243, and then transports the water to the heating box 21 through the water supply pipe 244. Several connecting pipes 245 on the water supply pipe 244 introduce hot water into each heat dissipation copper pipe 232. The hot water flows in the heat dissipation copper pipe 232, providing a heat source for the heat dissipation copper pipe 232. As the hot water flows in the heat dissipation copper pipe 232, the heat dissipation copper pipe 232 begins to dissipate heat. Start the fan 233 to guide the hot air radiated by the heat dissipation copper pipe 232 into the frying chamber 11. At this time, the hot air is delivered from the auxiliary heating mechanism 2 to the frying chamber 11 through the air duct 26. Then start the geared motor 14. The output shaft of the geared motor 14 drives the rotating shaft 13 to rotate through the coupling. The rotating shaft 13 drives the rake 12 in the frying chamber 11 to rotate. Then put the tea leaves to be fried into the frying chamber 11 for frying.

[0034] During the heating process, the second water pump 251 is turned on. The second water pump 251 draws water from the auxiliary water tank 231 through the liquid extraction pipe 252, and guides the water in the auxiliary water tank 231 that has been cooled back to the hot water tank 241 through the return pipe 253, so as to realize the recycling of water source and maintain the heat stability of the entire heating system.

[0035] Meanwhile, based on the type and quantity of tea leaves and the actual needs of fixing, the flow rate and volume of hot water in the heat dissipation copper pipe 232 are controlled by adjusting the working frequency of the first water pump 242 and the second water pump 251, thereby adjusting the temperature and heat of the hot air introduced into the roasting chamber 11 to achieve the best fixing effect.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
