[0002] In the processing of matcha (the raw material for tea), there is a very important step: after the green leaves are steamed to kill the greenness, they need to be roasted in a matcha roasting oven to develop a special roasted aroma (roasting aroma) and to better preserve the original green color of the raw material. Color preservation and roasting aroma are the two most important indicators of a matcha roasting oven.

[0003] A document with publication number (CN207963365U) discloses a tea drying machine based on drum turning technology, including a box body and a drying drum. The inner cavity of the box body is provided with a dustproof net, a drying drum and a second guide plate from top to bottom. The top of the box body is connected to an exhaust pipe. The drying drum is rotatably connected to the box body via a rotating shaft. The lowest end of the rotating shaft is provided with a discharge hole that cooperates with a guide hopper.

The bottom of the box body is provided with several legs evenly. A support plate is provided between all the legs. A purification box is provided at the top of the support plate.

[0004] In the roasting of tea, the above-mentioned device turns the tea leaves up and down to roast them. However, the device does not have any internal components that move the tea leaves. In contrast, existing devices that can turn the tea leaves have fixed internal components that cannot move. As a result, the tea leaves are carried by the components during the turning process, and the tea leaves cannot be turned and roasted evenly.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the technical problems of tea roasting, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A drum-type tea roasting device includes a roasting component for roasting tea leaves. The roasting component includes a cylinder, a limiting ring, a cleaning zone, a drive motor, and a stirring plate. The cylinder is connected to the output end of the drive motor. The limiting rings are symmetrically arranged on one end of the cylinder, and each limiting ring is fixedly connected to the cylinder. The stirring plate surrounds one end of the cylinder, and each stirring plate is elastically connected to the cylinder. The cleaning zone is located on the cylinder.

[0008] In a preferred embodiment of this utility model, support wheels are symmetrically arranged at both ends of the cylinder, and the corresponding support wheels are rotatably connected to brackets. Multiple support frames are fixedly connected to one end of the bracket, one of which is fixedly connected to a drive motor. The output end of the drive motor is fixedly connected to a drive wheel, and the drive wheel is driven by a transmission ring, which is fixedly connected to the cylinder.

[0009] In a preferred embodiment of the present invention, a cavity is provided at one end of the cylinder, the stirring plate is slidably connected to the cavity at the corresponding position, and a spring is symmetrically provided on each stirring plate, with the end of each spring being fixedly connected to the corresponding stirring plate and the inner wall of the cavity.

[0010] In a preferred embodiment of the present invention, a push rod is fixedly connected to one end of each stirring plate, and a through hole for the push rod to move is opened at one end of the cylinder, and each push rod is engaged with the same push block.

[0011] In a preferred embodiment of the present invention, the push block is semi-circular in shape, and the bottom of the push block is fixedly connected to the corresponding support frame. The push block is rotatably connected to one end of the cylinder, and grooves are arrayed on the push block.

[0012] In a preferred embodiment of the present invention, one of the limiting rings is fixedly connected to one end of the cylinder, and the other limiting ring is disposed in the middle of the cylinder. The other limiting ring is used to separate the stirring plate area from the impurity removal area, and the other limiting ring is fixedly connected to the cylinder.

[0013] In a preferred embodiment of the present invention, a cleaning zone is provided at the other end of the cylinder, a screening groove is provided on the inner wall of the cleaning zone, and spiral plates are symmetrically arranged on the inner wall of the cleaning zone, with each spiral plate fixedly connected to the inner wall of the cleaning zone.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This drum-type tea roasting equipment feeds tea leaves into the drum from one end. A drive motor drives the drum to rotate slowly. During rotation, a stirring plate tumbles the tea leaves at the bottom, ensuring even roasting and preventing tea leaves from accumulating at the bottom of the drum during rotation. Accumulated tea leaves lead to uneven roasting and affect the roasting quality. As the tea leaves are tumbled by the stirring plate, the corresponding stirring plate rotates to its corresponding position and is then shaken by other components within the roasting assembly. This shaking of the stirring plate will cause the tea leaves to be tumbled, but the tea leaves at the corners of the stirring plate and the drum wall will be shaken, preventing them from remaining in the same position during the roasting process. This would prevent the tea leaves from being in contact with the drum wall for a long time, thus affecting the roasting quality.

[0016] 2. The absence of a push block at the bottom of this drum-type tea grinding and roasting equipment prevents the bottom stirring plate from being unable to move a large amount of tea leaves during the tea leaf turning process caused by the presence of the push block, thus affecting the tea leaf turning and roasting process.

[0017] 3. This drum-type tea grinding and roasting equipment uses the rapid rotation of the drum to drive the impurity removal zone. The tea leaves are sieved by the screening trough in the impurity removal zone, removing the dust and broken tea leaves generated during the roasting process. No further screening is required, reducing operation steps and improving work efficiency. In addition, during the screening of the tea leaves, the guiding action of the spiral plate guides and turns the tea leaves, which quickly cools the tea leaves while removing the dust and broken tea leaves mixed in with them.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model 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 this utility model.

[0027] Please see Figure 1-5A drum-type tea roasting device includes a roasting component for roasting tea leaves. The roasting component includes a drum body 1, limiting rings 11, a cleaning zone 12, a drive motor 22, and stirring plates 31. The drum body 1 is connected to the output end of the drive motor 22. The limiting rings 11 are symmetrically arranged on one end of the drum body 1, and each limiting ring 11 is fixedly connected to the drum body 1. The stirring plates 31 surround one end of the drum body 1, and each stirring plate 31 is elastically connected to the drum body 1. The cleaning zone 12 is located on the drum body 1. Tea leaves are fed into the drum body 1 from one end. The drive motor 22 drives the drum body 1 to rotate slowly. During rotation, the stirring plates... The stirring plate 31 causes the tea leaves at the bottom to turn over, which ensures that the tea leaves are roasted evenly. This prevents the tea leaves from piling up at the bottom of the cylinder 1 during rotation, as this would lead to uneven roasting and affect the quality of the roasted tea leaves. As the tea leaves are turned over by the stirring plate 31, the corresponding stirring plate 31 rotates to the corresponding position and is then shaken by other components in the roasting assembly. The shaking of the stirring plate 31 will cause the tea leaves at the corners of the stirring plate 31 and the wall of the cylinder 1 to shake, preventing the tea leaves from moving and remaining in the same position during the roasting process. This would prevent the tea leaves from being in contact with the wall of the cylinder 1 for a long time, which would affect the roasting quality.

[0028] The device has an electric heating wire installed in the area of ​​the stirring plate 31. Since the electric heating wire is a well-known technology in the field, it is not disclosed in detail in this article. Moreover, this device is designed for the fine drying stage. Therefore, the electric heating wire controls the temperature at 40-60℃ through electronic control and performs continuous drying for 6 to 20 hours, thereby fully stimulating the "fuxiaxiang" umami amino acids such as theanine and glutamic acid, avoiding high-temperature charring, preserving the bright green color, and reducing the final moisture content of the tea leaves to 3% to 5%.

[0029] The cylinder 1 has symmetrical support wheels 21 at both ends, and the corresponding support wheels 21 are rotatably connected to brackets 2. One bracket 2 at one end is fixedly connected to multiple support frames 25, one of which is fixedly connected to a drive motor 22. The output end of the drive motor 22 is fixedly connected to a drive wheel 23, and the drive wheel 23 is driven by a transmission ring 24. The transmission ring 24 is fixedly connected to the cylinder 1. The drive motor 22 drives the drive wheel 23 to rotate through its output end. During the rotation of the drive wheel 23, the transmission ring 24 is driven to rotate through direct contact. The transmission ring 24 drives the cylinder 1 to rotate. The cylinder 1 is supported by the support wheels 21 during rotation. The drive motor 22 drives the cylinder 1 to rotate slowly first and roast the tea. After roasting, the drive motor 22 drives the cylinder 1 to rotate quickly, sending the tea leaves in the stirring plate 31 area into the impurity removal area 12 area. The device is tilted towards the other end of the cylinder 1 and appropriately towards the impurity removal area 12 area.

[0030] The cylinder 1 has a cavity at one end, and a stirring plate 31 is slidably connected to the cavity at a corresponding position. Each stirring plate 31 is symmetrically equipped with a spring 33, and the end of each spring 33 is fixedly connected to the corresponding stirring plate 31 and the inner wall of the cavity. A push rod 32 is fixedly connected to one end of each stirring plate 31. One end of the cylinder 1 has a through hole for the push rod 32 to move, and each push rod 32 is engaged with the same pushing block 3. The pushing block 3 is semi-circular in shape, and its bottom is fixedly connected to the corresponding support frame 25. The pushing block 3 is rotatably connected to one end of the cylinder 1. Grooves are arrayed on the pushing block 3. As the cylinder 1 rotates, it drives each stirring plate 31 to rotate as well. The rotation of the stirring plate 31 moves the tea leaves accumulated at the bottom, causing them to be evenly roasted by turning them over, preventing the tea leaves from piling up and affecting the roasting quality. Furthermore, when the bottom stirring plate 3... 1. After moving to the bottom of the push block 3, the push rod 32 is pushed by the edge of the push block 3. The push rod 32 drives the stirring plate 31, and the stirring plate 31 compresses the spring 33. The spring 33 is compressed and deformed, and the deformation force is applied to the stirring plate 31. When the push rod 32 moves to the groove position on the push block 3, the spring 33 pushes the stirring plate 31 and the push rod 32 downward through the deformation force. The push rod 32 is stuck in the groove of the push block 3. During continuous rotation, the stirring plate 31 in the bottom area of ​​the cylinder 1 is continuously driven to move, while the stirring plate 31 in the non-bottom area continues to shake. During the shaking, the tea leaves are shaken out from the corner area of ​​the stirring plate 31 and the wall of the cylinder 1. The tea leaves do not need to move to the high point before they fall out from the corner area of ​​the stirring plate 31 and the wall of the cylinder 1. This avoids the tea leaves from being in contact with the wall of the cylinder 1 for too long, which would affect the roasting quality.

[0031] The absence of the bottom area of ​​the push block 3 prevents the bottom stirring plate 31 from being unable to move a large amount of tea leaves during the tea leaf turning process caused by the presence of the push block 3, thus affecting the tea leaf turning and roasting process.

[0032] One of the limiting rings 11 is fixedly connected to one end of the cylinder 1, and the other limiting ring 11 is located in the middle of the cylinder 1. The other limiting ring 11 is used to separate the stirring plate 31 area from the impurity removal area 12 area. The other limiting ring 11 is fixedly connected to the cylinder 1. During the slow rotation and roasting of the cylinder 1, the limiting ring 11 blocks and limits the tea leaves to prevent them from directly entering the impurity removal area 12 area. After the tea leaves are roasted, the drive motor 22 drives the cylinder 1 to rotate rapidly. During the rapid rotation of the cylinder 1 and under the action of the tilt angle, the cylinder 1 conveys the tea leaves toward the impurity removal area 12 area.

[0033] The other end of the cylinder 1 has a cleaning zone 12. The inner wall of the cleaning zone 12 is provided with a screening groove. Spiral plates 13 are symmetrically arranged on the inner wall of the cleaning zone 12. Each spiral plate 13 is fixedly connected to the inner wall of the cleaning zone 12. When the tea leaves enter the cleaning zone 12, the rapid rotation of the cylinder 1 drives the cleaning zone 12. The tea leaves are screened by the screening groove of the cleaning zone 12, and the dust and broken tea leaves generated during the tea roasting process are screened out. No further screening is required, reducing operation steps and improving work efficiency. In addition, during the screening of the tea leaves, the spiral plates 13 guide and turn the tea leaves, which cools the tea leaves quickly and screens out the dust and broken tea leaves mixed in with the tea leaves.

[0034] Working principle: Tea leaves are fed into the cylinder 1 from one end. The drive motor 22 drives the cylinder 1 to rotate slowly. During rotation, the stirring plate 31 agitates the tea leaves at the bottom, ensuring even roasting and preventing tea leaves from accumulating at the bottom of the cylinder 1, which would lead to uneven roasting and affect the quality of the roasted tea. As the tea leaves are agitated by the stirring plate 31, the corresponding stirring plate 31 rotates to its corresponding position and is then shaken by other components within the roasting assembly. This shaking of the stirring plate 31 agitates the tea leaves, but the tea leaves at the edges and corners of the cylinder 1 wall are not affected by the shaking. To prevent the tea leaves from remaining in the same position during the turning and roasting process, which would cause them to remain in contact with the wall of the cylinder 1 for an extended period and affect the roasting quality, the drive motor 22 drives the drive wheel 23 to rotate via its output end. The drive wheel 23, in turn, drives the transmission ring 24 to rotate via direct contact transmission. The transmission ring 24 then drives the cylinder 1 to rotate. The cylinder 1 is supported by the support wheel 21 during rotation. The drive motor 22 initially drives the cylinder 1 to rotate slowly for roasting. After roasting, the drive motor 22 drives the cylinder 1 to rotate rapidly, sending the tea leaves in the stirring plate 31 area into the impurity removal zone. The device is tilted towards the other end of the cylinder 1 and appropriately tilted towards the impurity removal zone 12. As the cylinder 1 rotates, each stirring plate 31 rotates accordingly. The rotating plates 31 move the tea leaves accumulated at the bottom, causing them to be evenly roasted by turning them over, preventing the accumulation of tea leaves from affecting the roasting quality. When the bottom stirring plate 31 moves to the bottom of the pushing block 3, the push rod 32 is pushed by the edge of the pushing block 3. The push rod 32 drives the stirring plate 31, compressing the spring 33. The spring 33 deforms under compression and applies the deformation force to the stirring plate 31. When the push rod 32 moves to the bottom of the pushing block 3, the tea leaves accumulate at the bottom of the cylinder 1 and are roasted evenly by turning them over. After the rod 32 moves to the groove position on the push block 3, the spring 33 pushes the stirring plate 31 and the push rod 32 downward through the deformation force. The push rod 32 is stuck in the groove of the push block 3. During continuous rotation, the stirring plate 31 in the bottom area of ​​the cylinder 1 is continuously driven to move, while the stirring plate 31 in the non-bottom area continues to shake. During the shaking, the tea leaves are shaken out from the corner area of ​​the stirring plate 31 and the wall of the cylinder 1. The tea leaves do not need to move to the high point before they fall out from the corner area of ​​the stirring plate 31 and the wall of the cylinder 1, thus avoiding the tea leaves from being in contact with the wall of the cylinder 1 for too long, which would affect the roasting quality.The absence of the bottom area of ​​the push block 3 prevents the bottom stirring plate 31 from being unable to move a large amount of tea leaves during the tea leaf turning process, thus affecting the tea leaf turning and roasting. During the slow rotation and roasting of the cylinder 1, the limiting ring 11 blocks and limits the tea leaves, preventing them from directly entering the impurity removal zone 12. After the tea leaves are roasted, the drive motor 22 drives the cylinder 1 to rotate rapidly. During the rapid rotation of the cylinder 1 and under the action of the tilt angle, the tea leaves are conveyed towards the impurity removal zone 12. When the tea leaves enter the impurity removal zone 12, the rapid rotation of the cylinder 1 drives the impurity removal zone 12, and the tea leaves are screened by the screening trough of the impurity removal zone 12. The dust and broken tea leaves generated during the tea leaf roasting are screened out, eliminating the need for subsequent screening operations, reducing operation steps, and improving work efficiency. In addition, during the screening of the tea leaves, the guiding action of the spiral plate 13 guides and turns the tea leaves, which cools the tea leaves quickly and screens out the dust and broken tea leaves mixed in with them. ;
