Description

Technical Field

[0001] This invention belongs to the field of tea roasting and roasting technology, specifically, it relates to a portable tea roasting and roasting machine. Background Technology

[0002] Fixing (or killing the green) is a crucial step in tea processing. Its core purpose is to inhibit oxidation and deterioration by deactivating polyphenol oxidase in fresh leaves through high temperatures, while simultaneously evaporating some moisture to soften the leaves and facilitate subsequent processing. The effectiveness of fixing directly determines the tea's color, aroma, and taste—key quality indicators. Currently, the market offers tea fixing equipment ranging from large industrial-grade to small household or workshop-style machines. Smaller machines are gaining popularity due to their suitability for home processing and small-batch tea garden operations. However, existing small-scale tea fixing equipment still suffers from significant drawbacks in practical applications, limiting its operational efficiency and user experience.

[0003] Specifically, after the existing tea fixing equipment completes the fixing process, the fixing pot is in a high-temperature state because it is in direct contact with the heat source. If the unloading operation is carried out directly at this time, the manual contact with the high-temperature pot body is very likely to cause burns, which poses a serious safety hazard. Therefore, operators often need to wait for the fixing pot to cool down to a safe temperature naturally before they can carry out manual unloading. This cooling and waiting process takes a long time, which greatly extends the overall cycle of a single fixing operation and leads to low work efficiency.

[0004] In view of this, the present invention is proposed. Summary of the Invention

A drying component is also installed on the side wall of the base. The drying component is used to extract heat from the heating cylinder body to dry the tea leaves.

[0008] A positioning seat is installed on the base, a swing arm is rotatably installed on the positioning seat, a connecting arm is installed at the end of the swing arm, the end of the connecting arm is installed on the side wall of the blanching pot, a top rod is vertically inserted into the swing arm, a rocker arm is installed at the rotation center of the connecting arm, the rocker arm is movably connected to the top rod, and the bottom of the top rod is slidably set in the combination groove opened in the side wall of the positioning seat;

[0009] The combined trough includes a guide trough, which is used to deflect towards the rotation center of the swing arm, guide the top rod to move downward, and drive the blanching pot to rotate synchronously to ensure that the blanching pot is in a horizontal state. The end of the guide trough is provided with a discharge trough, which is a straight trough. The discharge trough is used to guide the top rod to move outward, so that the blanching pot is flipped over as a whole, which facilitates the discharge of material later.

[0010] In a preferred embodiment of the present invention, the heating cylinder body has a pair of handles on its side wall, the handles are fitted with heat insulation sleeves, the base is fitted with an anti-slip pad, and an electric heating tube is installed inside the heating cylinder body for heating the blanching pot.

[0011] In a preferred embodiment of the present invention, the drying assembly includes a hot air base, which is mounted on a base. A baffle plate is installed at the bottom of the inner cavity of the hot air base, and several pairs of tea drying cages of the same specifications are stacked on top of the hot air base. This allows for continuous changes in the position of the tea drying cages at different heights during the drying process, resulting in more uniform drying.

[0012] In a preferred embodiment of the present invention, a gas delivery pipe is connected inside the hot air base. The end of the gas delivery pipe is connected to the heating chamber inside the heating cylinder body. A blower is also connected to the heating chamber. The blower is used to deliver external cold air to the heating area of ​​the heating cylinder body for heating and to deliver the heated gas to the drying component.

[0013] In a preferred embodiment of the present invention, a frame is mounted on the base, a dual-axis motor is mounted on the frame, the output end of the dual-axis motor is movably connected to the positioning seat, and the side wall of the output end of the dual-axis motor is connected to the swing arm.

[0014] In a preferred embodiment of the present invention, a strip groove is provided on the rocker arm, a slide rod is slidably arranged inside the strip groove, a synchronization frame is installed on the slide rod, the synchronization frame is L-shaped, and the bottom of the synchronization frame is connected to the top rod, and the rocker arm is in an inclined state.

[0015] In a preferred embodiment of the present invention, a baffle is installed on the top rod, a limiting plate is sleeved on the outer wall of the top rod, the limiting plate is installed on the side wall of the connecting arm, a return spring is sleeved on the outer wall of the top rod, one end of the return spring is engaged with the baffle, the other end of the return spring is engaged with the limiting plate, and a protrusion is installed at the bottom of the top rod, the protrusion being slidably disposed in the combination groove.

[0016] In a preferred embodiment of the present invention, the initial end of the guide groove is connected to a tilting groove, the tilting groove is an arc groove, the unloading groove is a reset groove, and the reset groove and the tilting groove have the same radius of curvature. A partition is provided at the connection between the reset groove and the guide groove, and a torsion spring is installed at the rotation center of the partition. When the push rod slides along the tilting groove to the guide groove, the partition blocks the reset groove.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This invention has two main advantages. First, through the coordinated operation of a dual-axis motor, swing arm, top rod, and combined groove, the pan can be started directly after fixation without waiting for it to cool down. The motor drives the swing arm to rotate, causing the bottom protrusion of the top rod to slide along the combined groove. Under the guidance of the guide groove, the fixation pan remains horizontal during rotation to prevent tea leaves from falling off. After entering the unloading trough, the entire fixation pan can be flipped to achieve mechanical unloading, which improves work efficiency, ensures operational safety, and prevents the tea leaves from spoiling due to over-fermentation. Second, the integrated design of the fixation and drying components facilitates easy handling by operators, making it suitable for processing small samples of tea tree breeding materials on-site or at home. It can be used in various scenarios such as workshops and courtyards, and can ensure the stability of operation. In terms of operation, the withering stage is heated quickly by electric heating tubes, and in the drying stage, the residual heat of the withering components is transported to the drying components through the gas conveying pipe by the blower, without the need for additional heating devices; thirdly, a heat regulating air plate is arranged in the middle of the bottom of the drying device, so that part of the hot air is transported from both sides to the rear half of the bottom of the device, and part of the hot air is returned to the front half of the drying device by the baffle plate, so that the temperature of the entire drying device is uniform; fourthly, the stacked tea drying cages can be adjusted to achieve uniform drying, effectively reducing energy consumption and processing and maintenance costs and improving quality.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0030] Example 1:

[0031] like Figures 1 to 6 As shown, a portable tea roasting and drying machine includes a base 1.

[0032] A heating cylinder body 2 is installed on the base 1. The heating area of ​​the heating cylinder body 2 is equipped with a blanching pot 4. A drying component is also installed on the side wall of the base 1. The drying component is used to extract heat from the heating cylinder body 2 to dry the tea leaves.

[0033] A positioning seat 13 is installed on the base 1. A swing arm 12 is rotatably installed on the positioning seat 13. A connecting arm 11 is installed at the end of the swing arm 12. The end of the connecting arm 11 is installed on the side wall of the blanching pot 4. A top rod 20 is vertically inserted on the swing arm 12. A rocker arm 16 is installed at the rotation center of the connecting arm 11. The rocker arm 16 is movably connected to the top rod 20, and the bottom of the top rod 20 is slidably set in the combination groove opened in the side wall of the positioning seat 13.

[0034] The combined trough includes a guide trough 26, which is used to deflect towards the rotation center of the swing arm 12, guide the push rod 20 to move downward, and drive the blanching pot 4 to rotate. During this process, the blanching pot 4 deflects synchronously to ensure that the blanching pot 4 is in a horizontal state. A discharge trough 27 is provided at the end of the guide trough 26. The discharge trough 27 is a straight trough and is used to guide the push rod 20 to move outward, so that the blanching pot 4 can be flipped over as a whole, which facilitates the subsequent discharge.

[0035] like Figures 1 to 6 As shown in the specific embodiment, the heating cylinder body 2 has a pair of handles 3 on its side wall, and the side wall of the handles 3 is equipped with a heat insulation sleeve. The bottom of the base 1 is equipped with an anti-slip pad, and an electric heating tube is installed inside the heating cylinder body 2, which is used to heat the blanching pot 4. The handles 3, together with the heat insulation sleeve, facilitate the handling of the equipment and prevent burns. The anti-slip pad enhances the stability of the base 1. The electric heating tube directly provides an efficient heat source to the blanching pot 4. All three together improve the portability, safety, and blanching efficiency of the equipment.

[0036] like Figures 1 to 6 As shown, the drying assembly further includes a hot air base 6, which is mounted on the base 1. A baffle plate 61 is installed at the bottom of the inner cavity of the hot air base 6. The baffle plate 61 ensures that the hot air entering the hot air base 6 is dispersed, preventing uneven drying caused by the hot air converging on one side of the base if no baffle plate is installed. Several pairs of identical, stacked tea drying baskets 7 are arranged on the top of the hot air base 6, allowing for continuous adjustment of the positions of the tea drying baskets 7 at different heights during the drying process. The hot air base 6 provides drying support, and the stacked tea drying baskets 7 can be flexibly adjusted to achieve uniform drying.

[0037] like Figures 1 to 6 As shown, the hot air base 6 is further connected to a gas delivery pipe 5. The end of the gas delivery pipe 5 is connected to the heating chamber inside the heating cylinder body 2. A blower 10 is also connected to the heating chamber, and the blower 10 is used to deliver external cold air to the heating area of ​​the heating cylinder body 2 for heating, and to deliver the heated gas to the drying assembly. By connecting the heating chamber and the hot air base 6 through the gas delivery pipe 5, and cooperating with the blower 10 to deliver airflow, the waste heat of the heating cylinder body 2 can be recovered and utilized, eliminating the need for an additional drying heat source and reducing energy consumption.

[0038] Example 2:

[0039] The difference between the above embodiments and this embodiment is that: Figures 1 to 6As shown, a frame 15 is mounted on the base 1, and a dual-axis motor 14 is mounted on the frame 15. The output end of the dual-axis motor 14 is movably connected to the positioning seat 13, and the side wall of the output end of the dual-axis motor 14 is connected to the swing arm 12. The frame 15 provides stable mounting support for the dual-axis motor 14, which directly drives the swing arm 12 to rotate, replacing manual operation, improving the automation level of the equipment, and reducing labor intensity.

[0040] like Figures 1 to 6 As shown, in a specific embodiment, the rocker arm 16 has a strip groove 17, and a slide rod 18 is slidably disposed inside the strip groove 17. A synchronization frame 19 is mounted on the slide rod 18. The synchronization frame 19 is L-shaped, and its bottom is connected to the top rod 20. The rocker arm 16 is in an inclined state. Through the sliding cooperation between the strip groove 17 and the slide rod 18, the L-shaped synchronization frame 19 realizes the flexible linkage between the top rod 20 and the rocker arm 16. The inclined rocker arm 16 optimizes the direction of force transmission, ensuring that the deflection action of the blanching pan 4 is smooth and stable.

[0041] like Figures 1 to 6 As shown, furthermore, a baffle 21 is installed on the push rod 20, and a limiting plate 23 is sleeved on the outer wall of the push rod 20. The limiting plate 23 is installed on the side wall of the connecting arm 11, and a return spring 22 is sleeved on the outer wall of the push rod 20. One end of the return spring 22 is engaged with the baffle 21, and the other end is engaged with the limiting plate 23. A protrusion 24 is installed at the bottom of the push rod 20, and the protrusion 24 is slidably disposed in the combination groove. The baffle 21 and the limiting plate 23 limit the extension range of the return spring 22, the return spring 22 provides elastic return force, and the protrusion 24 ensures stable sliding cooperation between the push rod 20 and the combination groove, thereby improving the accuracy of the movement of the push rod 20 and the reliability of the return.

[0042] like Figures 1 to 6 As shown, further, the initial end of the guide groove 26 is connected to a tilting groove 25, which is an arc groove. The unloading groove 27 is a reset groove 28, and the reset groove 28 and the tilting groove 25 have the same radius of curvature. A partition 29 is provided at the connection between the reset groove 28 and the guide groove 26. A torsion spring 30 is installed at the rotation center of the partition 29. When the push rod 20 slides along the tilting groove 25 to the guide groove 26, the partition 29 blocks the reset groove 28. When the push rod 20 slides along the reset groove 28 to the tilting groove 25, the partition 29 is squeezed and covered on the guide groove 26, ensuring that the push rod 20 moves to the tilting groove 25. The tilting groove 25 provides initial positioning for the push rod 20. The reset groove 28 cooperates with the guide groove 26 to complete the switching of the unloading and reset trajectories. The partition 29 and the torsion spring 30 achieve unidirectional conduction, avoiding interference with the movement trajectory of the push rod 20 and ensuring that the unloading and reset processes are carried out in an orderly manner.

[0043] Experimental example:

[0044] Drying methods and effects

[0045] Existing aroma extraction machine: Initial heat is set at 120°C to 130°C, leaf thickness is spread to about 1cm to 2cm, time is about 10min to 15min, no stirring is done in the middle, rehydration time is 10min to 15min, then the heat is set at 90°C to 100°C, leaf thickness is spread to 1cm to 2cm, no stirring is done in the middle, time is 10min to 15min, total time is 20min to 30min + rehydration time of 10min to 15min, total time is 30min to 45min.

[0046] This invention's integrated drying machine: First, the kneaded leaves are lightly heated at a fixed temperature of 120℃~130℃, with the leaves spread to a thickness of about 1cm. During the drying process, the degree of moisture loss of the tea leaves is sensed by hand. Every 1~2 minutes, the position of the drying basket is changed from bottom to top, and the leaves are turned over once. The temperature is changed from the bottom layer (120℃~130℃) to the top layer (90℃). Then, the second to last layer is placed on top, and the third to last layer is placed on top, and so on, continuously cycling. Each layer differs by about 5℃~10℃ from top to bottom: 90℃→95℃→100℃→105℃→110℃→120℃~130℃. The frequency of changing the position of the drying basket can be flexibly adjusted according to the degree of moisture loss of the tea leaves. Remove the tea leaves when they feel slightly prickly to the touch, about 6-7 minutes, with a moisture content of 15%-20%. After removing the tea, allow it to rehydrate for 10-15 minutes. Then, apply the final heat at 90°C-100°C, spreading the leaves 1-2cm thick, using the same method as the initial heat. The bottom layer temperature should be 100°C, and the top layer temperature 75°C-80°C. Dry for 4-5 minutes, with a moisture content of 5%-6%. The tea is considered properly dried when it can be easily crumbled into powder by hand. The total drying time for the initial and final heat is 10-12 minutes, plus 10-15 minutes of rehydration, for a total of 20-27 minutes.

[0047] I. Core Differences Between Existing Flavor-Enhancing Machines and the Integrated Blanching and Drying Machine of This Invention

[0048] 1. Existing aroma-enhancing machines: are mostly static with a constant temperature (mostly a single high temperature of 120℃, without being turned over during operation), resulting in uneven contact between the tea leaves and the heat medium, with localized overheating and undercooking coexisting.

[0049] 2. Innovation of this technology: Dynamic tumbling + stepped cooling circulating baking, the core of which is uniform heat and mass transfer and controllable reaction. Its biochemical and heat transfer principles are as follows:

[0050] Stepped temperature change + cyclic stirring: Dynamic stirring ensures uniform heating, and the stepped cooling from 120°C to 90°C to 95°C to 100°C to 105°C to 110°C to 120°C achieves gradient temperature control and cyclic reaction, allowing the contents to gradually transform through repeated cycles.

[0051] 3. The core principle of aroma differences

[0052] (1) Heat transfer and moisture removal: Uniform dehydration determines the aroma base

[0053] Existing aroma extraction machines use direct drying, which causes surface moisture to quickly vaporize and form a crust. Without turning the machine over during the process, internal moisture migration is hindered, resulting in a dry exterior and a moist interior. Localized high temperatures can also cause sudden moisture loss, damaging cell structure and causing a large amount of low-boiling-point aromatic substances (such as linalool and linalool) to escape, while high-boiling-point aromas cannot be synthesized in time.

[0054] This invention features an integrated withering and drying machine: Tumbling + Stepped Cooling: Tumbling breaks the surface water film, allowing heat to penetrate the leaves evenly; stepped cooling matches the decreasing moisture content of the tea leaves.

[0055] High temperature range of 110℃~120℃: rapidly breaks down enzymes, deactivates oxidases, fixes tea aroma precursors, and evaporates free water;

[0056] Cooling section from 90℃ to 100℃: This slows down the rate of water loss, allows the bound water inside to migrate out slowly, avoids the release of aroma, and provides a mild environment for biochemical reactions.

[0057] (2) Key biochemical reactions in aroma formation: gradient temperature control is "precise synthesis"

[0058] The aroma of roasted tea mainly comes from the Maillard reaction (a non-enzymatic reaction in which reducing sugars and amino acids / proteins undergo heating to produce aroma substances), caramelization (a dehydration, decomposition and polymerization reaction in which monosaccharides / disaccharides undergo high-temperature heating with or without the participation of amino acids to produce aromatic flavors), and isomerization of terpenes.

[0059] Stepped temperature change perfectly matches the reaction temperature range:

[0060] High temperature range of 110℃~120℃: Triggers the initial stage of Maillard reaction, where amino acids and reducing sugars generate aldehydes, ketones and furan-based aroma precursors, while degrading grassy substances and removing raw grassy smell.

[0061] In the 100℃~110℃ medium temperature range: the Maillard reaction enters the middle stage, the precursor polymerizes to produce pyrazine, thiazole and other nutty and roasted aromas, the caramelization reaction proceeds gently, producing a sweet caramel aroma;

[0062] Low temperature range of 90℃~100℃: The reaction slows down, stabilizes the aroma substances that have been generated, promotes the isomerization of terpenes (such as linalool being converted into a more persistent aroma form), and reduces the burnt smell produced by high temperature pyrolysis.

[0063] Cyclic operation: Multiple gradient temperature changes allow the reaction to occur in steps, in depth and in a balanced manner, resulting in a layering of aromas; while direct drying either results in insufficient reaction (undercooked) or local over-pyrolysis (burnt), resulting in a single and thin aroma.

[0064] (3) The two key functions of dynamic mixing in this technology

[0065] Eliminating heat transfer dead zones: In static drying, the temperature is low and the reaction is weak at the piled-up areas of tea leaves, while the surface temperature is high and it is easy to scorch; turning and stirring allow each tea leaf to alternately contact the heat source, resulting in a uniform reaction throughout the leaves and no raw / scorched off-flavors.

[0066] Promotes the release and balance of aroma substances: The stirring creates a micro-airflow, which promptly removes CO2 and low-boiling-point off-flavors generated during baking, while retaining high-boiling-point premium aromas and avoiding musty or rancid tastes.

[0067] (4) Tea tissue structure and aroma retention

[0068] Existing technology: High temperature and sudden heating cause leaf cells to burst and cell walls to collapse, destroying the aroma storage structure, resulting in rapid aroma dissipation and short-lasting fragrance.

[0069] This invention utilizes a stepped, tumbling process to gently dehydrate cells, resulting in more regular cell shrinkage. This allows aromatic substances to combine with pectin and polysaccharides to form a slow-release system, resulting in a more lasting and richer aroma in the finished product.

[0070] II. Summary

[0071] Existing technologies employ extensive dehydration, resulting in insufficient conversion and loss of aroma precursors, as well as uneven heating. This invention utilizes a combination of stirring and stepped temperature-changing circulation to precisely control the biochemical synthesis of tea aromas. Through uniform heat transfer, gradient-matched reaction temperature zones, and dynamic impurity removal, it achieves the removal of low-boiling-point off-flavors and the layered synthesis of high-boiling-point aromas, ultimately resulting in a richer, more complex aroma and a fresher, more mellow taste. See the table below for details:

[0072] The test results show that the products made using this multi-functional integrated machine have significantly improved quality, especially in terms of aroma and taste, which surpass the control (existing aroma-enhancing machine).

[0073] The implementation principle of the portable tea roasting and drying machine of the present invention is as follows:

[0074] First, the tea leaves are subjected to the fixation process. The tea leaves to be fixed are placed in the fixation pot 4. At this time, the protrusion 24 at the bottom of the top rod 20 is in the initial position of the turning groove 25, and the fixation pot 4 remains horizontal and stable for processing. The anti-slip pad at the bottom of the base 1 effectively improves the overall stability of the equipment. The heating element inside the heating cylinder body 2 is activated, heating the fixation pot 4 to achieve the desired temperature for fixation. The operator can move the equipment via the handle 3 on the side wall of the heating cylinder body 2. The heat insulation sleeve on the handle 3 provides good protection against burns. During the fixation process, the tea leaves can be manually turned as needed to ensure even fixation.

[0075] After the initial processing is complete, the operator unloads the tea leaves. At this time, the dual-axis motor 14 on the frame 15 is started. The output of the dual-axis motor 14 drives the swing arm 12 to rotate around the positioning seat 13. The protrusion 24 at the bottom of the push rod 20 first slides along the flipping groove 25 towards the guide groove 26. During the sliding process, the partition 29 blocks the reset groove 28 under the action of the torsion spring 30 to prevent the push rod 20 from accidentally entering. Under the guidance of the guide groove 26, the push rod 20 deflects towards the rotation center of the swing arm 12 and moves downward. The push rod 20 drives the slide rod 18 to slide in the strip groove 17 of the rocker arm 16 through the synchronous frame 19. The rocker arm 16 is installed at the rotation center of the connecting arm 11, thereby driving the initial processing pot 4 to deflect synchronously during the rotation, always maintaining a horizontal state to prevent the tea leaves from falling.

[0076] When the dual-axis motor 14 continuously drives the swing arm 12 to rotate, the protrusion 24 at the bottom of the push rod 20 enters the unloading groove 27 (i.e., the reset groove 28) along the end of the guide groove 26. The unloading groove 27 is a straight groove. The guide drives the push rod 20 to move outward through the reset spring 22. The push rod 20 drives the blanching pot 4 to rotate as a whole through the connecting arm 11, which facilitates the rapid unloading of materials after subsequent processing or cleaning.

[0077] After unloading, the dual-axis motor 14 rotates in reverse, and the protrusion 24 at the bottom of the push rod 20 slides along the reset groove 28 to the flip groove 25. At this time, the protrusion 24 presses the partition 29, the torsion spring 30 is deformed by force, and the partition 29 is pressed and covered on the guide groove 26 to ensure that the push rod 20 moves smoothly to the flip groove 25, ensuring the reset accuracy of the push rod 20. The equipment returns to the initial state and waits for the next operation.

[0078] After the fixation is completed, the fixed tea leaves are transferred to the tea drying basket 7 on top of the hot air base 6. The side walls are equipped with symmetrically distributed handles 8. Several pairs of stacked tea drying baskets 7 can be adjusted to different heights to make the tea dry more evenly.

[0079] Then, the blower 10 is started, and the blower 10 delivers external cold air to the heating chamber of the heating cylinder body 2. After the cold air is heated by the electric heating tube, it is delivered to the hot air base 6 through the gas delivery pipe 5. The heat is transferred from the hot air base 6 to each layer of tea drying cage 7 to realize the drying operation of the tea. This process makes full use of the residual heat of the heating cylinder body 2 and improves the energy utilization efficiency.

[0080] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
