Description

Technical Field

[0001] The present invention relates to the technical field of tea making, and in particular to a baking device for tea refining and a use method thereof. Background Art

[0002] Tea roasting technology is a key link in the tea refining process. It refers to the process of drying, enhancing the aroma and transforming the quality of tea through thermal action. Its core principle is to use appropriate temperature and time to promote changes inside the tea leaves, remove excess moisture, prevent mildew and improve storage resistance. Through Maillard reaction and caramelization reaction, it promotes the formation of aroma substances, while reducing undesirable components such as astringency and bitterness, making the tea soup taste more mellow and sweet. This technology is widely used in oolong tea, black tea and dark tea, and is the core process for forming the unique flavor characteristics of tea.

[0003] After searching, the Chinese patent with publication number CN116746619A discloses a tea refining baking device, including a transmission shaft, the outer surface of the transmission shaft is movably connected to a heating tube, one side of the inner cavity of the heating tube is movably connected to a terminal post, the outer surface of the heating tube is movably connected to a drum screen, and one end of the drum screen is fixedly connected to one side of the outer surface of the transmission shaft by a bolt, and the outer surface of the drum screen is movably connected to an outer shell. The present application provides a tea refining baking device and baking method. The arrangement of the heating tube, the drum screen and the outer shell can bake the tea leaves stirred in the drum screen in a non-contact manner, effectively preventing the water vapor in the atmosphere from entering the tea leaves with the hot air. At the same time, the arrangement of the outer shell and its upper structure can timely condense the evaporated water vapor in the tea leaves into water droplets and discharge them out, thereby effectively improving its baking efficiency and quality for the tea leaves. However, when this solution is actually used, it still has the following shortcomings: In order to improve the efficiency of tea processing, a multi-layer baking method is often used in the baking oven to increase the baking output. Therefore, each time baking is performed, it is necessary to manually remove the shelves of each layer and take out the baked tea leaves, and then replenish the shelves of each layer with new tea leaves to be baked, which affects the efficiency of baking production. In addition, since manual intervention is required at the beginning and end of baking, it is impossible to produce tea automatically and quickly. Moreover, if the tea leaves are only baked flat during drying, the tea leaves on the inner side will be heated unevenly, and the degree of baking will be less than that of the tea leaves on the outer side, which will lead to uneven quality of the tea output.

[0004] Therefore, the present application provides a tea refining baking device and a method of use to meet the needs of automatic loading and unloading and uniform baking. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a tea refining baking device and a method of use, so as to solve the problems of cumbersome manual loading and unloading and uneven baking.

[0010] Preferably, the baking plate is arranged in a ring shape, an axis groove is opened on the inner side wall of the baking plate, a rotating shaft slidably connected to the axis groove is fixedly mounted on the sleeve, a limit block adapted to the baking plate is fixedly mounted on the end of the mounting ring close to the notch, a counterweight block is fixedly mounted on the end of the bottom of the baking plate away from the notch, and the top of the sleeve is fixedly connected to the bottom of the fixed shaft.

[0011] Preferably, the leveling assembly includes a guide frame fixedly installed in the baking box, a sliding rod is slidably installed in the guide frame, a plurality of pressure rods adapted to the baking plates are fixedly installed on the sliding rod, an electric telescopic rod is fixedly installed on the inner side wall of the top of the baking box, and the movable end of the electric telescopic rod is fixedly connected to the top of the sliding rod.

[0012] Preferably, a slot matching the pressure rod is provided on the counterweight block, an operating rod matching the slot is fixedly installed on the bottom of the sliding rod, both the slot and the operating rod are provided with rounded corners, and a cleaning arm matching the discharge port is fixedly installed on the driving rod.

[0013] Preferably, sealing plates are slidably mounted on the feed port and the discharge port, and an electric push rod is fixedly mounted between the sealing plates and the baking box.

[0014] Preferably, a storage box is slidably mounted on the bottom of the base plate.

[0015] A tea refining baking method comprises the following steps: Step 1: Ensure the baking box is closed and sealed. The notches on all baking plates are located below the feed port. The sliding plates are retracted into the clearance slots. The sealing plates close the feed port and the discharge port to prevent the tea from spilling. Open the sealing plate at the feed port and start the servo motor. The servo motor begins to rotate. Step 2: Tea leaves are automatically added into the baking box at a uniform speed through the feed port. The tea leaves first pass through the gaps on each baking plate and reach the bottom in turn. The servo motor drives the driving rod to rotate, first contacting the fixed plate on the bottom layer, driving the sliding plate to move out of the gap and fill the gap on the baking plate. Under the action of the driving rod, the baking plate and the sleeve are driven to rotate along the driving shaft for one circle, so that the tea leaves are evenly spread on the baking plate on the bottom layer. After one circle, the fixed shaft on the bottom layer drives the mounting ring and the linkage rod thereon to rotate to the fixed plate on the second sliding plate at the bottom, driving the sliding plate on the second layer to move out of the gap and fill the gap on the baking plate. The tea leaves fall on the baking plate on the second layer, and under the action of the linkage rod, the baking plate, sleeve and fixed shaft of the second layer are driven to rotate along the fixed shaft of the first layer. This process is repeated until all baking plates are covered with tea leaves. Step 3: Under the action of the counterweight and the limit block, the baking plate remains stationary, and the tea leaves fall onto the baking plate. As the servo motor rotates, the electric telescopic rod changes the distance between the pressure rod and the baking plate, thereby adjusting the thickness of the baked tea leaves. Under the action of the pressure rod, the tea leaves on the baking plate are spread flat to a preset height; Step 4: The servo motor rotates to drive the driving rod. Under the action of the corrugated ring, the rotating ring moves up and down relative to the driving shaft. The rotating ring drives the sleeve mounted on the driving shaft to vibrate up and down, which in turn drives all the baking plates to vibrate up and down, shaking the tea leaves evenly. Step 5: After baking is completed, the sealing plate at the discharge port is opened, the servo motor reverses, and the rotating ring drives the driving rod to reverse. After the driving rod reverses one circle, it contacts the other end of the fixed plate, drives the sliding plate to move into the make way slot, and opens the gap on the baking plate. The servo motor continues to rotate, driving the sliding plates of each layer to move into the make way slot and open the corresponding gap in turn, and finally the gap is located above the discharge port. The pressure rod and the operating rod are driven upward by the electric telescopic rod to adapt to the card slot set on the counterweight block, driving the baking plate to rotate around the sleeve along the rotating shaft and tilt toward the gap, pouring the tea leaves into the discharge port from the gap. After confirming that all the tea leaves have been discharged, turn off the servo motor and reset the electric telescopic rod, close the sealing plate at the discharge port, and restore the baking box to a closed and sealed state.

[0016] Beneficial effects of the present invention: 1. This tea refining baking device and method of use, by providing a feed inlet and a discharge inlet, automatically adds tea leaves into the baking box at a uniform speed through the feed inlet. Utilizing the corresponding relationship between the sliding plates, the clearance grooves, and the notches, the tea leaves fall sequentially onto the baking plates, achieving automatic loading and unloading, eliminating the need for manual loading and unloading, significantly saving labor costs and improving production efficiency. The design of multi-layer baking plates and the automatic feeding and uniform spreading mechanism can maximize the amount of tea leaves roasted within a limited space, fully utilizing the internal space of the baking box, improving the utilization rate of the baking equipment, and thus improving overall baking efficiency. 2. This tea refining baking device and its use method, by providing a servo motor to drive the driving rod to rotate, cooperates with the fixed plate, sliding plate and other structures, so that when the tea leaves fall onto the baking plate, the sliding plate fills the gap in turn and drives the baking plate to rotate, and the tea leaves fallen on the baking plate are evenly spread to a preset height by the action of the pressing rod, which can ensure that the tea leaves on each layer of baking plate are evenly distributed, ensuring uniform baking and effectively improving the baking quality. In addition, the electric telescopic rod can be used to change the distance between the pressing rod and the baking plate, thereby adjusting the thickness of the baked tea leaves, so that the baking equipment can adapt to the baking needs of different types of tea with different process requirements, thereby improving the versatility and flexibility of the equipment; 3. This tea refining roasting device and its use method utilizes a servo motor to rotate a driving rod. Under the action of a corrugated ring, the rotating ring moves up and down relative to the driving shaft, thereby driving all baking plates to vibrate up and down. This can evenly disperse the tea leaves, preventing tea accumulation and uneven roasting. This allows the tea leaves to more fully contact the heat source, achieving a uniform and efficient roasting effect and improving roasting quality. 4. This baking device and method for refining tea leaves, by providing an electric telescopic rod to drive the pressure rod and the operating rod to move upward, which is adapted to the slot on the counterweight block, drives the baking plate to rotate around the sleeve along the rotating shaft and tilt toward the notch, and pours the tea leaves into the discharge port from the notch. At the same time, the reciprocating motion of the electric telescopic rod can also achieve a vibration effect on the baking plate, so that the tea leaves can be automatically discharged faster and more thoroughly, avoiding tea leaves from being missed, improving the utilization rate of the tea leaves, and reducing production costs.

At this time, the tea leaves can be evenly laid on the baking plates 34 at the bottom, and at the same time, when rotating one circle, the tea leaves are evenly spread on the baking plates 34 at the bottom. After a week, the fixed shaft 36 of the bottom layer drives the mounting ring 46 and the linkage rod 47 thereon to rotate to the fixed plate 42 on the second layer sliding plate 41 at the bottom, and drives the sliding plate 41 of the second layer to move out of the clearance groove 4 and fill the gap on the baking plate 34, so that the tea leaves fall on the baking plate 34 of the second layer, and under the action of the linkage rod 47, the baking plate 34, the sleeve 33 and the fixed shaft 36 of the second layer are driven to rotate along the fixed shaft 36 of the first layer, and the process is repeated until all baking plates 34 are covered with tea leaves, realizing automatic feeding and automatically laying tea leaves evenly on each baking layer. The plate 34 is used to maximize the amount of roasted tea leaves while realizing automation and improving roasting efficiency. When discharging, the notch of the baking plate 34 on the bottom layer is located at the position of the discharge port 38. At this time, the servo motor 31 is reversed to make the rotating ring 43 drive the driving rod 45 to reverse.

[0024] like Figure 6 and Figure 7As shown, the baking plate 34 is arranged in an annular shape, and an axis groove 5 is opened on the inner wall of the baking plate 34. A rotating shaft 51 that is slidably connected to the axis groove 5 is fixedly installed on the sleeve 33. A limit block that is adapted to the baking plate 34 is fixedly installed on the end of the mounting ring 46 close to the notch. A counterweight block 52 is fixedly installed on the end of the bottom of the baking plate 34 away from the notch. The top of the sleeve 33 is fixedly connected to the bottom of the fixed shaft 36; the leveling assembly includes a guide frame 6 fixedly installed in the baking box 1, and a slide rod is slidably installed in the guide frame 6. 61, a plurality of pressure rods 62 adapted to the baking plate 34 are fixedly mounted on the slide rod 61, an electric telescopic rod 63 is fixedly mounted on the inner side wall of the top of the baking box 1, and the movable end of the electric telescopic rod 63 is fixedly connected to the top of the slide rod 61; a slot adapted to the pressure rod 62 is provided on the counterweight block 52, and an operating rod 64 adapted to the slot is fixedly mounted on the bottom of the slide rod 61, and both the slot and the operating rod 64 have rounded corners. A cleaning arm adapted to the discharge port 38 is fixedly mounted on the driving rod 45; When feeding, under the action of the counterweight block 52 and the limit block, when the tea leaves fall on the baking plate 34, the baking plate 34 remains stationary, and while rotating with the servo motor 31, the tea leaves fallen on the baking plate 34 can be spread to a preset height under the action of the pressure rod 62, and the distance between the pressure rod 62 and the baking plate 34 can be changed by the electric telescopic rod 63 to adjust the thickness of the baked tea leaves, thereby adapting to different baking needs, and when discharging, the pressure rod 62 and the operating rod 64 can be driven upward by the electric telescopic rod 63, which can be adapted to the card slot provided on the counterweight block 52 above it, driving the baking plate 34 to rotate around the sleeve 33 along the rotating shaft 51, thereby tilting toward the notch, and pouring the tea leaves from the notch into the discharge port 38.

[0025] A tea refining baking method comprises the following steps: Step 1: Ensure that the baking box 1 is closed and sealed, the notches on all baking plates 34 are located below the feed port 37, the sliding plate 41 is retracted into the clearance groove 4, the sealing plate 7 closes the feed port 37 and the discharge port 38 to prevent the tea leaves from scattering, the sealing plate 7 at the feed port 37 is opened, and the servo motor 31 is started, and the servo motor 31 begins to rotate; The tea leaves are then put into the baking box 1 at a uniform speed through the feeding port 37. The tea leaves first pass through the gaps on each baking plate 34 and reach the bottom in turn. The servo motor 31 drives the driving rod 45 to rotate, first contacting the fixed plate 42 of the bottom layer, driving the sliding plate 41 to move out of the gap 4, filling the gaps on the baking plates 34. Under the action of the driving rod 45, the baking plates 34 and the sleeve 33 are driven to rotate along the driving shaft 32 for one circle, so that the tea leaves are evenly spread on the baking plates 34 of the bottom layer. After one circle of rotation, the fixed shaft 36 of the bottom layer drives the mounting ring 46 and the linkage rod 47 thereon to rotate to the fixed plate 42 on the second sliding plate 41 of the bottom layer, driving the sliding plate 41 of the second layer to move out of the gap 4, filling the gaps on the baking plates 34, and the tea leaves fall on the baking plates 34 of the second layer. Under the action of the linkage rod 47, the baking plates 34, the sleeve 33 and the fixed shaft 36 of the second layer are driven to rotate along the fixed shaft 36 of the first layer. This process is repeated until all baking plates 34 are covered with tea leaves. Step 3: Under the action of the counterweight 52 and the limit block, the baking plate 34 remains stationary, and the tea leaves fall onto the baking plate 34. While the servo motor 31 rotates, the electric telescopic rod 63 changes the distance between the pressing rod 62 and the baking plate 34, thereby adjusting the thickness of the baked tea leaves. Under the action of the pressing rod 62, the tea leaves falling on the baking plate 34 are spread flat to a preset height. Step 4: The servo motor 31 rotates and drives the driving rod 45 to rotate. Under the action of the corrugated ring 48, the rotating ring 43 moves up and down relative to the driving shaft 32. The rotating ring 43 drives the sleeve 33 mounted on the driving shaft 32 to vibrate up and down, thereby driving all the baking plates 34 to vibrate up and down, shaking the tea leaves evenly. After baking is completed, the sealing plate 7 at the discharge port 38 is opened, the servo motor 31 is reversed, and the rotating ring 43 drives the driving rod 45 to reverse. After the driving rod 45 reverses one circle, it contacts the other end of the fixed plate 42, drives the sliding plate 41 to move into the make way slot 4, and opens the gap on the baking plate 34. The servo motor 31 continues to rotate, driving the sliding plates 41 of each layer to move into the make way slot 4 and open the corresponding gap, and finally makes the gap above the discharge port 38. The pressure rod 62 and the operating rod 64 are driven to move upward by the electric telescopic rod 63, and are adapted to the card slot provided on the counterweight block 52, driving the baking plate 34 to rotate around the sleeve 33 along the rotating shaft 51, tilting toward the gap, and pouring the tea leaves from the gap into the discharge port. After confirming that all the tea leaves have been discharged, the servo motor 31 is turned off and the electric telescopic rod 63 is reset, and the sealing plate 7 at the discharge port 38 is closed, so that the baking box 1 is restored to a closed and sealed state.

[0026] The technical solution provided by the present invention automatically adds tea leaves into the baking box 1 at a uniform speed through the feed port 37. At this time, the notches on each baking plate 34 are all located below the feed port 37, and the sliding plate 41 is recovered in the clearance groove 4. During the process of pouring the tea leaves, they first pass through the notches on each baking plate 34 to reach the bottom in turn, and the servo motor 31 drives the driving rod 45 to rotate, first contacting the fixed plate 42 of the bottom layer and driving the sliding plate 41 to move out of the clearance groove 4 and fill the notches on the baking plates 34. Under the action of the driving rod 45, the baking plates 34 and the sleeves 33 are driven to rotate one circle along the driving shaft 32. At this time, the tea leaves can be evenly laid on the baking plates 34 of the bottom layer. At the same time, after one circle of rotation, the fixed shaft 36 of the bottom layer drives the mounting ring 46 thereon and the linkage rod 47 rotates to the fixed plate 42 on the second layer sliding plate 41 at the bottom, and drives the sliding plate 41 of the second layer to move out of the clearance groove 4 and fill the gap on the baking plate 34, so that the tea leaves fall on the baking plate 34 of the second layer, and under the action of the linkage rod 47, drives the baking plate 34, the sleeve 33 and the fixed shaft 36 of the second layer to rotate along the fixed shaft 36 of the first layer, and repeats this process until all baking plates 34 are covered with tea leaves, realizing automatic feeding while automatically and evenly spreading the tea leaves on each layer of baking plates 34, maximizing the amount of baked tea leaves while realizing automation and improving baking efficiency. When discharging, the gap of the baking plate 34 of the bottom layer is located at the position of the discharge port 38. At this time, the servo motor 31 reverses to make the rotating ring 43 drive the driving The rod 45 is reversed, and after one rotation, it can contact the other end of the fixed plate 42, thereby driving the sliding plate 41 to move into the clearance groove 4 and open the gap on the baking plate 34, so that the tea leaves of the first layer can be poured out through the discharge port 38, and in the process of the servo motor 31 continuing to rotate, the sliding plates 41 of each layer are driven to move into the clearance groove 4 and open the corresponding gaps, and the final gap is located above the discharge port 38, so that the tea leaves on all the baking plates 34 are automatically poured out from the discharge port 38, realizing automatic discharge and saving manual operation costs. At the same time as baking, the servo motor 31 rotates to drive the driving rod 45 to rotate, and under the action of the corrugated ring 48, the rotating ring 43 moves up and down relative to the driving shaft 32, and drives the rotating ring 43 sleeved on the driving shaft 32 The sleeve 33 on the upper part vibrates up and down, thereby driving all baking plates 34 to vibrate up and down, thereby shaking the tea leaves evenly, closing the sealing plate 7, and realizing the process of automatic feeding. Under the action of the counterweight block 52 and the limit block, when the tea leaves fall on the baking plate 34, the baking plate 34 remains stationary, and while rotating with the servo motor 31, under the action of the pressure rod 62, the tea leaves fallen on the baking plate 34 can be spread to a preset height, and the distance between the pressure rod 62 and the baking plate 34 can be changed by the electric telescopic rod 63 to adjust the thickness of the baked tea leaves, thereby meeting different baking requirements. When discharging, the electric telescopic rod 63 drives the pressure rod 62 and the operating rod 64 to move up, which can adapt to the card slot provided on the counterweight block 52 above it.The baking plate 34 is driven to rotate around the sleeve 33 along the rotating shaft 51, thereby tilting toward the notch, and pouring the tea leaves from the notch into the discharge port 38.

10. A tea refining baking method, based on a tea refining baking device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Ensure that the baking box (1) is in a closed and sealed state, that the notches on all baking plates (34) are located below the feed port (37), that the sliding plate (41) is retracted into the clearance groove (4), that the sealing plate (7) closes the feed port (37) and the discharge port (38) to prevent the tea leaves from scattering, that the sealing plate (7) at the feed port (37) is opened, that the servo motor (31) is started, and that the servo motor (31) begins to rotate; Step 2: The tea leaves are automatically added into the baking box (1) at a uniform speed through the feed port (37). The tea leaves first pass through the gaps on each baking plate (34) and reach the bottom. The servo motor (31) drives the driving rod (45) to rotate, first contacting the fixed plate (42) at the bottom, driving the sliding plate (41) to move out of the clearance groove (4) and fill the gap on the baking plate (34). Under the action of the driving rod (45), the baking plate (34) and the sleeve (33) are driven to rotate along the driving shaft (32) for one circle, so that the tea leaves are evenly spread on the baking plate (34) at the bottom. Afterwards, the fixed shaft (36) of the bottom layer drives the mounting ring (46) and the linkage rod (47) thereon to rotate to the fixed plate (42) on the second sliding plate (41) at the bottom, driving the sliding plate (41) of the second layer to move out of the clearance groove (4) and fill the gap on the baking plate (34). The tea leaves fall on the baking plate (34) of the second layer, and under the action of the linkage rod (47), the baking plate (34) of the second layer, the sleeve (33) and the fixed shaft (36) are driven to rotate along the fixed shaft (36) of the first layer. The process is repeated until all baking plates (34) are covered with tea leaves. Step 3: Under the action of the counterweight (52) and the limit block, the baking plate (34) remains stationary, and the tea leaves fall on the baking plate (34). While the servo motor (31) rotates, the distance between the pressing rod (62) and the baking plate (34) is changed by the electric telescopic rod (63), thereby adjusting the thickness of the baked tea leaves. Under the action of the pressing rod (62), the tea leaves falling on the baking plate (34) are spread to a preset height. Step 4: The servo motor (31) rotates to drive the driving rod (45) to rotate. Under the action of the corrugated ring (48), the rotating ring (43) moves up and down relative to the driving shaft (32). The rotating ring (43) drives the sleeve (33) mounted on the driving shaft (32) to vibrate up and down, thereby driving all the baking plates (34) to vibrate up and down, thereby evenly shaking the tea leaves. Step 5: After baking is completed, the sealing plate (7) at the discharge port (38) is opened, the servo motor (31) is reversed, and the rotating ring (43) drives the driving rod (45) to reverse. After the driving rod (45) reverses one circle, it contacts the other end of the fixed plate (42), drives the sliding plate (41) to move into the clearance groove (4), and opens the gap on the baking plate (34). The servo motor (31) continues to rotate, and drives the sliding plates (41) of each layer to move into the clearance groove (4) and open the corresponding gap, and finally makes the gap at the discharge port. Above the material opening (38), the electric telescopic rod (63) drives the pressure rod (62) and the operating rod (64) to move upward, and adapt to the card slot provided on the counterweight block (52), driving the baking plate (34) to rotate around the sleeve (33) along the rotating shaft (51), tilting toward the notch, and pouring the tea leaves from the notch into the material opening. After confirming that all the tea leaves have been discharged, the servo motor (31) is turned off and the electric telescopic rod (63) is reset, and the sealing plate (7) at the material opening (38) is closed, so that the baking box (1) returns to a closed and sealed state.
