Description

Technical Field

[0001] This invention relates to the field of tea processing technology, and in particular to a far-infrared ceramic roasting machine for tea. Background Technology

[0002] In the tea processing industry, roasting is one of the key processes determining the flavor and quality stability of the finished tea. This is especially true for traditional teas like Wuyi Rock Tea, which possess a unique "rocky" flavor, where the roasting process directly impacts its aroma layers and taste. While traditional charcoal roasting imparts a distinctive charcoal flavor to tea, it suffers from low thermal efficiency, uneven temperature distribution, high labor intensity, and heavy reliance on operator experience, making it difficult to meet the demands of modern tea production for standardization, energy conservation, and large-scale operations. In recent years, new heat source technologies such as electric heating and infrared radiation have been gradually applied to tea roasting equipment. Although these technologies have improved temperature control accuracy and automation to some extent, common problems remain, including insufficient heat utilization, poor uniformity of the flow field within the roasting chamber, and inadequate humidity control. These issues lead to uneven heating of the tea, high energy consumption, and affect the consistency of the final product quality. Furthermore, existing equipment does not adequately consider waste heat recovery and recycling, resulting in energy waste, increased difficulty in environmental control, and hindering further improvements in the efficiency of tea roasting production. Therefore, there is an urgent need to develop a new type of tea roasting equipment that can replicate the flavor of traditional processes while achieving efficient heat utilization, precise temperature and humidity control, and automated operation, so as to promote the transformation and upgrading of tea processing technology towards green, intelligent, and standardized directions.

[0060] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the invention. Similarly, the following embodiments are only some, not all, embodiments of the present invention, and all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0061] Please see Figures 1 to 6This embodiment provides a far-infrared ceramic roasting machine for tea, including: a housing 1, an air outlet assembly 2, an air inlet assembly 3, a tea-turning assembly 4, and a heating assembly 5. The housing 1 has an air inlet 11, a first air outlet 12, a second air outlet 13, a heating chamber, a first air supply channel 14, and a second air supply channel 15. The air inlet 11 is located at the bottom of the housing 1, the first air outlet 12 is located on the side wall of the housing 1, the first air supply channel 14 and the second air supply channel 15 are arranged opposite each other on the inner side of the housing 1, and the second air outlet 13 is located between the first air supply channel 14 and the second air supply channel 15. The air outlet assembly 2 is located between the first air outlet 12 and the second air outlet 13. The air outlet assembly 2 includes a dehumidifier 21, which is used to dehumidify the air at the second air outlet 13 before it re-enters the housing 1 through the first air outlet 12. The air inlet assembly 3 includes... The system includes a first fan unit 31 and a second fan unit 32. The first fan unit 31 is located at the entrance of the first air supply channel 14, and the second fan unit 32 is located at the entrance of the second air supply channel 15. The tea-turning assembly 4 includes a tea tray 41, a flip plate assembly 42, and a first transmission assembly 43. The first transmission assembly is connected to the flip plate assembly 42. The flip plate assembly 42 is located on the tea tray 41, and the tea tray 41 is slidably connected to the housing 1. The heating assembly 5 includes a first heating plate assembly 51, a second heating plate assembly 52, and a far-infrared heating assembly 53. The first heating plate assembly 51 is located at the output end of the first air supply channel 14, the second heating plate assembly 52 is located at the output end of the second air supply channel 15, and the far-infrared heating assembly 53 is located above the tea tray 41. The far-infrared heating assembly 53 includes multiple far-infrared ceramic heating tubes, which are distributed in a preset manner above the tea tray 41.

[0062] In this embodiment, the housing 1 serves as the main support structure of the device. An air inlet 11 at its bottom is used to introduce external air, a first air outlet 12 on the side wall is used to discharge treated dry, hot air, and a second air outlet 13, located between the first air supply channel 14 and the second air supply channel 15, is used to discharge humid, hot exhaust gas. The first air supply channel 14 and the second air supply channel 15 are symmetrically distributed inside the housing 1, forming a bidirectional air supply path to ensure uniform airflow distribution within the heating chamber.

[0063] The air outlet assembly 2 connects the first air outlet 12 and the second air outlet 13. Its core component, the dehumidifier 21, adopts a combination of condensation and adsorption technology to efficiently remove moisture from the air discharged from the second air outlet 13. The dried air is then sent back into the housing 1 through the first air outlet 12 for recycling, significantly improving the thermal energy utilization rate.

[0064] The air intake assembly 3 includes a first fan unit 31 and a second fan unit 32, which are respectively located at the inlets of the first air supply channel 14 and the second air supply channel 15. The coordinated operation of the two fans enhances the stability of air supply and the controllability of flow rate.

[0065] In the tea-turning assembly 4, the tea tray 41 is connected by a sliding mechanism to facilitate loading and unloading of tea leaves. The flipping plate assembly 42 consists of multiple flipping plates and is used to turn the tea leaves during the roasting process. The first transmission assembly 43 drives the flipping plate assembly 42 to move through a sprocket and chain mechanism to ensure that the tea leaves are heated evenly.

[0066] The first heating plate group 51 and the second heating plate group 52 of the heating assembly 5 are located at the output ends of the first air supply channel 14 and the second air supply channel 15, respectively. Preferably, they are made of honeycomb ceramic heating bricks, which have the characteristics of strong heat storage capacity and uniform radiation. The far-infrared heating group 53 is set above the tea tray 41 and consists of multiple far-infrared ceramic heating tubes distributed in a preset array to directly radiate heat to the tea leaves. Its wavelength matches the absorption characteristics of the tea leaves, promoting the evaporation of internal moisture and the transformation of flavor substances. The preset method can be a matrix-style uniform arrangement or an arc-shaped distribution matching the shape of the tea tray 41. Preferably, the far-infrared ceramic heating tubes and the ceramic heating bricks form a composite heat source, which can both rapidly heat up and maintain a stable temperature, adapting to the process requirements of different stages of tea roasting.

[0067] When this device is in operation, air enters through the air inlet 11, is pressurized by the first fan unit 31 and the second fan unit 32, and then sent into the first air supply channel 14 and the second air supply channel 15 respectively. It flows through the first heating plate group 51 and the second heating plate group 52 and is heated into hot air, which is then evenly blown from both sides onto the tea tray 41 inside the heating chamber. Simultaneously, the far-infrared heating group 53 radiates heat to the tea leaves from above, achieving multi-directional heating. The tea leaves are periodically turned by the tea-turning component 4 to ensure all-around heating. The humid and hot air is discharged from the second air outlet 13, dehumidified by the dehumidifier 21, and becomes dry hot air, which then flows back into the housing 1 through the first air outlet 12 for recycling. This process effectively maintains a stable temperature and controllable humidity inside the chamber, significantly improving thermal energy utilization efficiency.

[0068] This embodiment solves the problems of uneven heat distribution, high energy consumption, and insufficient temperature and humidity control precision in traditional tea roasting equipment by combining a composite heat source structure with a circulating dehumidification and air supply system. The bidirectional air supply channel and the evenly distributed far-infrared heating elements 53 ensure consistent heating of the tea leaves, preventing localized over- or under-roasting. The automated operation of the tea-turning component 4 reduces labor intensity and improves production efficiency. Waste heat recovery and recycling significantly reduce energy waste, meeting green production requirements. This device has a reasonable structure, is easy to operate, and is suitable for standardized roasting processing of various types of tea, effectively ensuring the stability and consistency of tea quality.

[0069] In some embodiments, the flap assembly 42 includes multiple flaps arranged sequentially and at intervals within the tea drawer 41. Each flap has a first drive shaft at one end and a first driven shaft at the other end. The first driven shaft is rotatably connected to the side wall of the tea drawer 41. The first transmission assembly 43 includes a first drive unit 431, a first drive wheel 432, multiple first driven wheels 433, and a first chain 434. The first drive wheel 432 is drive-connected to the output end of the first drive unit 431. Each first driven wheel 433 is drive-connected to a first drive shaft. The first chain 434 is sleeved on the first drive wheel 432 and the multiple first driven wheels 433.

[0070] In this embodiment, the flip-plate assembly 42 consists of multiple flip plates arranged at intervals inside the tea drawer 41 to turn the tea leaves during the roasting process to ensure even heating. Each flip plate has a first drive shaft at one end and a first driven shaft at the other end, wherein the first driven shaft is rotatably connected to the side wall of the tea drawer 41 to achieve stable support and rotational movement of the flip plate.

[0071] In the first transmission group 43, the first drive unit 431 serves as the power source, with its output end connected to the first drive wheel 432. Each first driven wheel 433 is connected to its corresponding first drive shaft. The first chain 434 is mounted on the first drive wheel 432 and all the first driven wheels 433, forming a closed-loop transmission structure. Preferably, the first chain 434 is a roller chain, and its pitch design is adapted to the low-speed, smooth movement requirements of tea leaf turning, reducing operating noise and wear. When the first drive unit 431 starts, it drives the first chain 434 to rotate through the first drive wheel 432, thereby driving all the first driven wheels 433 to rotate synchronously, ultimately enabling each flap to achieve a coordinated and consistent turning action.

[0072] When the tea-turning assembly 4 is working, the first drive unit 431 drives all the first driven wheels 433 to rotate synchronously through the first drive wheel 432 and the first chain 434, thereby driving each flip plate to rotate around the first driven shaft, so as to achieve uniform turning of the tea leaves in the tea drawer 41.

[0073] This embodiment uses a chain drive structure to ensure the synchronization and stability of the movement of multiple flippers, avoiding the unevenness problem of traditional manual flipping; the spacing and coordinated movement of the flippers ensure that the tea leaves are heated more fully, reducing local over-roasting or under-roasting; the overall structure is simple and reliable, reducing the complexity of equipment maintenance, while improving roasting efficiency and the consistency of tea quality.

[0074] In some embodiments, the tea-turning assembly 4 further includes a second transmission group 44, which is disposed between the first drive unit 431 and the first transmission group 43. The second transmission group 44 includes: a second drive wheel 441, a second driven wheel 442, a second driven shaft, and a second chain 443. The second drive wheel 441 is connected to the output end of the first drive unit 431; the second driven wheel 442 is drively connected to the first drive wheel 432; the second driven shaft is disposed between the second driven wheel 442 and the first drive wheel 432; and the second chain 443 is sleeved on the second drive wheel 441 and the second driven wheel 442.

[0075] In this embodiment, the second transmission group 44 serves as the power transmission mechanism between the first drive unit 431 and the first transmission group 43. Its second drive wheel 441 is directly connected to the output end of the first drive unit 431 to receive the initial power input. The second driven wheel 442 forms a transmission engagement with the second drive wheel 441 via the second chain 443. The second driven shaft is positioned between the second driven wheel 442 and the first drive wheel 432, serving to support and transmit torque. This structure achieves a two-stage reduction transmission through the sleeve connection of the second chain 443, effectively reducing the input speed of the first transmission group 43 and increasing the output torque, adapting to the low-speed, high-torque conditions required for tea leaf turning. Preferably, the second driven shaft is made of 45# steel, and its surface is hardened to improve wear resistance and load-bearing capacity. The second chain 443 is a roller chain with the same pitch as the first chain 434 to ensure the matching of the transmission system.

[0076] When the first drive unit 431 is started, the power is transmitted through the second drive wheel 441 to the second driven wheel 442 via the second chain 443, and then through the second driven shaft to drive the first drive wheel 432 to rotate, ultimately driving the first transmission group 43 to complete the tea-turning action.

[0077] This embodiment achieves a smooth transition and torque amplification of power transmission through a two-stage transmission structure, ensuring that the flipping plate group 42 can still operate stably under tea stacking conditions; the reduction transmission reduces the movement speed of the first transmission group 43, making the tea turning more gentle and uniform, and avoiding tea damage caused by violent movements; this transmission system has a compact structure, is easy to maintain, and improves the reliability and service life of the equipment.

[0078] In some embodiments, there are multiple tea trays 41, which are arranged vertically at intervals in the heating chamber; the number of first transmission groups 43 corresponds one-to-one with the number of tea trays 41, and multiple first driven wheels 433 are arranged at intervals along the extension direction of the tea trays 41; the number of second driven wheels 442 corresponds one-to-one with the number of first transmission groups 43, and multiple second driven wheels 442 are arranged vertically at intervals.

[0079] In this embodiment, multiple tea trays 41 are arranged vertically at intervals within the heating chamber, forming a layered roasting structure that can process multiple batches of tea simultaneously to improve production efficiency. Each tea tray 41 is equipped with an independent first transmission group 43, the number of which corresponds one-to-one with the number of tea trays 41, ensuring the independence of the tea-turning action for each layer. Multiple first driven wheels 433 are spaced apart along the extension direction of the tea tray 41, forming a stable transmission layout. Correspondingly, the number of second driven wheels 442 also matches the number of first transmission groups 43, and the multiple second driven wheels 442 are arranged vertically at intervals, constituting a vertical power transmission system. This layout allows each tea tray 41 to obtain independent tea-turning power, avoiding interference between layers. Preferably, the tea trays 41 are made of 304 stainless steel, and their surfaces are food-grade polished to ensure safe contact with tea leaves.

[0080] When the equipment is running, the second transmission group 44 transmits power to the first transmission group 43 of each layer through the vertically arranged second driven wheels 442, driving the flip-plate group 42 in each tea drawer 41 to operate independently. This embodiment significantly improves the space utilization and single-bake output of the equipment through the multi-layer tea drawer 41 structure; the independent transmission design ensures that the tea leaves in each layer do not interfere with each other, maintaining the consistency of the tea-flipping action; the vertical power layout saves horizontal space, making the equipment structure more compact; the temperature and humidity environment of each layer is relatively independent, which facilitates precise layer control, thereby improving the overall quality stability of tea roasting.

[0081] In some embodiments, the first heating plate group 51 includes a plurality of first heating plates arranged in a horizontal direction and facing the side of the tea drawer 41; the second heating plate group 52 includes a plurality of second heating plates arranged in a horizontal direction and facing the side of the tea drawer 41; the first heating plates and / or the second heating plates are configured as honeycomb ceramic heating bricks.

[0082] In this embodiment, the first heating plate group 51 includes multiple first heating plates arranged horizontally, facing the side of the tea tray 41 to form a side heating surface for the tea leaves. Similarly, the second heating plate group 52 also includes multiple horizontally arranged second heating plates, installed opposite to the first heating plate group 51, together forming a double-sided heating structure. The first and second heating plates use honeycomb ceramic heating bricks as heating elements. This material has a porous honeycomb structure, which can effectively increase the heating area and provide uniform infrared radiation. Preferably, the honeycomb pore size of the honeycomb ceramic heating brick is 1-2 mm, and the wall thickness is 0.3-0.5 mm, ensuring both mechanical strength and efficient thermal radiation performance. The surface of the heating plates undergoes a special glaze treatment, improving infrared emissivity while facilitating cleaning and maintenance.

[0083] When the equipment is working, the first heating plate group 51 and the second heating plate group 52 heat up simultaneously, converting electrical energy into far-infrared radiation energy through the honeycomb ceramic heating bricks, and uniformly heating the tea leaves in the tea tray 41 from both sides. This embodiment ensures the uniformity of heating of the tea leaves through the double-sided heating layout, avoiding the temperature gradient caused by unilateral heating; the honeycomb ceramic structure provides a larger effective heating area and higher thermal radiation efficiency; far-infrared radiation can directly penetrate the surface of the tea leaves, achieving synchronous heating inside and out, improving the utilization rate of thermal energy; the thermal inertia of the ceramic material helps to maintain temperature stability, reducing the impact of temperature fluctuations on the quality of the tea leaves, and ultimately achieving a highly efficient and uniform roasting effect.

[0084] In some embodiments, the first air supply channel 14 includes a first conveying section and a first diversion section arranged from bottom to top. The first diversion section includes multiple first diversion channels and a first guide plate 141 dividing the first diversion channels. The number of first diversion channels corresponds one-to-one with the number of tea drawers 41. The first diversion section is connected to the first conveying section. A first fan unit 31 is provided at the entrance of the first conveying section. A first heating plate group 51 is provided in the first diversion section. A first arc-shaped guide surface 142 is provided on the inner side of the first conveying section. The second air supply channel 15 includes a second conveying section and a second diversion section arranged from bottom to top. The second diversion section includes multiple second diversion channels and a second guide plate 151 dividing the second diversion channels. The number of second diversion channels corresponds one-to-one with the number of tea drawers 41. The second diversion section is connected to the second conveying section. A second fan unit 32 is provided at the entrance of the second conveying section. A second heating plate group 52 is provided in the second diversion section. A second arc-shaped guide surface 152 is provided on the inner side of the second conveying end.

[0085] In this embodiment, the first air supply channel 14 adopts a layered structure design, including a first conveying section and a first diversion section arranged from bottom to top. The first conveying section serves as the main air duct, and a first fan unit 31 is installed at its inlet to provide initial airflow power. The specially designed first arc-shaped guide surface 142 on the inner side can effectively reduce airflow resistance and achieve a smooth airflow transition. The first diversion section is divided into multiple first diversion channels by multiple first guide plates 141. The number of first diversion channels corresponds to the number of tea trays 41, ensuring that each tea tray 41 can obtain independent and uniform airflow distribution. The first heating plate group 51 is arranged in the first diversion section, so that the airflow is fully heated while being diverted.

[0086] Similarly, the second air supply duct 15 adopts a symmetrical structure, including a second conveying section and a second diversion section. A second fan unit 32 is installed at the inlet of the second conveying section, and a second arc-shaped guide surface 152 is provided on the inner side. The second diversion section is divided into multiple second diversion channels by a second guide plate 151, and the second heating plate group 52 is installed in the second diversion section. Preferably, the first guide plate 141 and the second guide plate 151 are made of aviation aluminum, and their windward surfaces adopt an airfoil curved surface design to further optimize the airflow distribution effect.

[0087] When the first fan unit 31 and the second fan unit 32 are started, the airflow enters the first conveying section and the second conveying section respectively, and smoothly enters the diversion section after being guided by the arc-shaped guide surface. In the first diversion section and the second diversion section, the airflow is evenly distributed to each diversion channel by the first guide plate 141 and the second guide plate 151 respectively, and is heated by the first heating plate group 51 and the second heating plate group 52 to form uniform hot air, which is finally sent out from the outlet facing the tea drawer 41.

[0088] This embodiment ensures a balanced distribution of hot air within the chamber through a dual-channel symmetrical design, avoiding temperature deviations caused by unilateral airflow. The one-to-one correspondence between the diversion channels and the tea trays 41 enables precise airflow distribution, ensuring consistent wind speed and temperature for each layer of tea. The arc-shaped guide surface combined with the airfoil guide plate design significantly reduces airflow resistance and improves airflow efficiency. The layout of the heating plate assembly built into the diversion section allows for full utilization of heat energy and reduces heat loss, ultimately achieving a highly efficient and uniform hot air circulation baking effect.

[0089] In some embodiments, the first fan unit 31 includes: a first suction duct, a first bracket, and a first fan. The first suction duct is disposed on the side wall of the housing 1; the first bracket is disposed on the first suction duct; and the first fan is disposed on the first bracket. The second fan unit 32 includes: a second suction duct, a second bracket, and a second fan. The second suction duct is disposed on the side wall of the housing 1, and the first suction duct and the second suction duct are disposed opposite to each other. The second bracket is disposed on the second suction duct; and the second fan is disposed on the second bracket.

[0090] In this embodiment, the first suction duct is fixed to the side wall of the housing 1, serving as an airflow passage; the first bracket is installed on the first suction duct to support the first fan; the first fan is fixed by the first bracket and is responsible for drawing air from the outside. The second fan unit 32 adopts a symmetrical design, including a second suction duct, a second bracket, and a second fan. The second suction duct is also located on the side wall of the housing 1, arranged opposite to the first suction duct, forming a bidirectional air intake structure; the second bracket is installed on the second suction duct to fix the second fan; the second fan is installed through the second bracket and works in conjunction with the first fan. Preferably, the first and second fans are centrifugal fans with backward-curved impellers, which have stable air pressure and low noise characteristics, and the outer shell is made of galvanized steel plate, which has good corrosion resistance.

[0091] When the equipment is running, the first and second fans start synchronously, drawing air from both sides of the equipment through the first and second suction ducts respectively, forming a symmetrical and balanced airflow input. This embodiment eliminates airflow deviation that may occur with unilateral air intake through the symmetrical layout of the dual fans, ensuring uniform airflow distribution within the air supply channel. The stable air pressure provided by the centrifugal fan ensures that the airflow can effectively penetrate the heating plate assembly and fully contact the tea leaves. The relatively opposite suction duct structure reduces airflow turbulence and lowers energy loss. The independent bracket installation method facilitates fan maintenance and replacement, improving the maintainability and service life of the equipment, ultimately achieving a highly efficient and stable airflow supply.

[0092] In some embodiments, the air intake assembly 3 further includes a second drive unit 33 and a baffle 34. The second drive unit 33 is disposed at the air inlet 11. The baffle 34 is connected to the second drive unit 33 and is used to close the air inlet 11.

[0093] In this embodiment, the air intake assembly 3 is supplemented with a second drive unit 33 and a baffle 34. The second drive unit 33 is located at the air inlet 11 and serves as the power source for the baffle 34; the baffle 34 is connected to the second drive unit 33 via a transmission mechanism and is used to open or close the air inlet 11. Preferably, the second drive unit 33 is an electric push rod with a thrust of 50N and a stroke of 100mm, which can precisely control the opening and closing angle of the baffle 34; the baffle 34 is made of 3mm thick aluminum plate, which has the characteristics of being lightweight and corrosion resistant.

[0094] When the air intake needs to be adjusted, the second drive unit 33 drives the baffle 34 to move, controlling the opening area of ​​the air intake channel by changing the relative position of the baffle 34 and the air inlet 11. This embodiment achieves precise adjustment of the air intake, which can flexibly adjust the air intake according to the needs of different tea types and roasting process stages; the sealing function of the baffle 34 can reduce heat loss and improve heat energy utilization when the equipment is preheating or paused; the automated control driven by the electric push rod reduces the intensity of manual operation, improves the convenience of equipment operation and the accuracy of process control, and ultimately achieves precise control of the airflow environment during the roasting process.

[0095] In some embodiments, the air outlet assembly 2 includes: a first air outlet duct 22 and a third fan 23. The first air outlet duct 22 is connected to the first air outlet 12 and the second air outlet 13. The third fan 23 is disposed on the first air outlet duct 22 and is disposed at the input end of the dehumidifier 21.

[0096] In this embodiment, the first air outlet duct 22 serves as an airflow channel, connecting with the first air outlet 12 and the second air outlet 13 to form a complete airflow circulation path. The third fan 23 is mounted on the first air outlet duct 22 and located at the input end of the dehumidifier 21, providing airflow power to draw humid and hot air from the second air outlet 13 to the dehumidifier 21. Preferably, the third fan 23 is a high-temperature resistant centrifugal fan, with its impeller and casing 1 made of high-temperature alloy to ensure long-term stable operation under high-temperature and high-humidity conditions.

[0097] When the equipment is running, the third fan 23 starts to generate negative pressure, drawing the humid, hot air from the tea leaves inside the heating chamber into the first air outlet duct 22 through the second air outlet 13, and then delivering it to the dehumidifier 21 for processing. In this embodiment, the negative pressure suction of the third fan 23 ensures the rapid discharge of humid, hot air, preventing moisture accumulation in the chamber. The optimized airflow path of the third fan 23 at the input end of the dehumidifier 21 reduces airflow resistance. The high-temperature resistant design ensures the reliability of the equipment in high-temperature baking environments, achieving efficient collection and delivery of humid, hot air, creating favorable conditions for subsequent dehumidification and waste heat recovery.

[0098] In some embodiments, the air outlet assembly 2 includes: a second air outlet duct 24 and a first drain duct 25. There are multiple second air outlet ducts 24, which are spaced apart in a vertical direction. The second air outlet ducts 24 are connected to the first air outlet duct 22. The first drain duct 25 is connected to the drain outlet of the dehumidifier 21.

[0099] In this embodiment, the air outlet assembly 2 is supplemented with a second air outlet duct 24 and a first drain duct 25. Multiple second air outlet ducts 24 are provided, arranged at intervals along the vertical direction, and connected to the first air outlet duct 22 to form a layered exhaust structure. The first drain duct 25 is directly connected to the drain outlet of the dehumidifier 21 to discharge condensate generated during dehumidification. Preferably, the second air outlet duct 24 is made of 310S heat-resistant stainless steel with a diameter of 60mm, capable of withstanding high-temperature exhaust gases above 200℃; the first drain duct 25 is made of corrosion-resistant PVC material, and the pipe wall is designed with a drainage slope to ensure smooth discharge of condensate.

[0100] When the equipment is running, the hot and humid exhaust gases from each layer are collected through the corresponding second exhaust duct 24 to the first exhaust duct 22, and then treated by the dehumidifier 21. The condensate generated during dehumidification is promptly discharged through the first drain duct 25. This embodiment achieves layered collection of exhaust gases through multi-layered second exhaust ducts 24, avoiding the mixing of exhaust gases from different temperature layers; high-temperature resistant materials ensure the long-term reliability of the piping system in high-temperature environments; dedicated drain ducts ensure timely discharge of condensate, preventing water accumulation from corroding the equipment and maintaining the efficient operation of the dehumidifier 21, ultimately achieving a systematic treatment of exhaust gas collection and condensate discharge.

[0101] By adopting the above technical solutions, the present invention differs from the prior art and has the following beneficial effects:

[0102] By combining a composite heat source structure with a circulating dehumidification and air supply system, precise control and high energy efficiency are achieved in the tea roasting process. The composite heat source, composed of honeycomb ceramic heating bricks and far-infrared ceramic heating tubes, ensures both uniform and penetrating heat radiation while achieving a balance between rapid heating and stable heat preservation. A bidirectional air supply channel, coupled with a layered airflow design, ensures uniform and stable hot air distribution in each tea tray 41, solving the problem of uneven heat distribution in traditional equipment. The automated tea-turning component 4, through a multi-stage transmission system, gently and evenly turns the tea leaves, avoiding inconsistencies caused by manual operation. The air outlet component 2 recovers waste heat, and the dehumidifier 21 efficiently treats the humid air, returning the dry hot air to the roasting chamber for reuse, significantly reducing energy consumption. This technical solution employs a modular design, with each functional component operating in coordination. While improving the consistency of tea roasting quality, it significantly increases production efficiency and energy utilization, providing a reliable standardized production solution for the tea processing industry.
