Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a stir-frying device for tea processing. Background Technology
[0002] Tea, as a traditional beverage, is loved by consumers all over the world. In the tea processing process, the quality of tea is the key factor that determines its market value and taste. Tea processing involves multiple stages, among which stir-frying is a crucial step. During stir-frying, tea leaves undergo complex physical and chemical changes, thus forming a unique aroma, taste and appearance.
[0003] Tea leaves, after being picked, consist of different parts, such as leaves, buds, and stems. During picking, transportation, and storage, tea leaves inevitably suffer some mechanical damage, causing some leaves to break. These broken parts will further form debris during the stir-frying process. In addition, during the stir-frying process, the tea leaves are constantly rolling and rubbing inside the wok, and collisions with the wok wall and stir-frying arms will also produce debris. Currently, after stir-frying, a screening process is usually added to remove these debris. The additional screening process increases the complexity of the processing, time costs, and labor costs. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tea-processing stir-frying device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tea processing stir-frying device, comprising a frame, a housing fixedly connected to the frame, a stir-frying cylinder rotatably connected to the housing, a heating chamber fixedly connected to the housing, an exhaust pipe fixedly connected to the housing, a sieving structure provided on the stir-frying cylinder, the sieving structure mainly consisting of several sieve holes, all of which are opened on the stir-frying cylinder, and a fixing cylinder fixedly connected to the housing, the fixing cylinder being sleeved on the outside of the stir-frying cylinder.
[0006] The effect achieved by the above-mentioned components is as follows: tea leaves are put into the frying drum, biomass pellet fuel is added to the heating chamber, and the drum is ignited to heat it. The drum is rotated, causing the tea leaves to tumble. Smoke is discharged through the exhaust pipe. As the tea leaves are frying with the rotation of the drum, smaller particles and debris will be discharged through several sieve holes into the fixed drum. No additional sieving is required, thus avoiding the current practice of adding a screening process to remove these debris after frying. The additional screening process increases the complexity of the processing flow, time costs, and labor costs.
[0007] Preferably, a discharge pipe is fixedly inserted into the heating chamber, and a guide groove is formed on the inner wall of the fixed cylinder, the guide groove being connected to the discharge pipe.
[0008] The effect achieved by the above components is as follows: after the debris enters the fixed cylinder, it enters the guide trough along the inner wall of the fixed cylinder. Since the end of the guide trough near the discharge pipe is lower than the other side, the debris will enter the discharge pipe along the guide trough and then be discharged.
[0009] Preferably, two fixing blocks are fixedly connected to the stir-frying drum, and a scraper is provided on both fixing blocks.
[0010] The effect achieved by the above components is that the rotation of the wok drum will drive the scraper to move, so that the scraper cleans the inner wall of the fixed drum and prevents it from sticking to the inner wall of the fixed drum.
[0011] Preferably, the fixing block has a sliding groove, and a sliding rod is slidably connected in the sliding groove, and the sliding rod is fixedly connected to the scraper.
[0012] The effect achieved by the above components is that the sliding rod drives the scraper to move, thereby adjusting the position of the sliding rod.
[0013] Preferably, a spring is fixedly connected to the inner wall of the chute, one end of the spring is fixedly connected to the slide rod, and two baffles are fixedly connected in the guide chute.
[0014] The effect achieved by the above components is as follows: when the scraper is in contact with the inner wall of the fixed cylinder, the spring is in a contracted state, so the spring rebound force acts on the slide rod, resulting in a better cleaning effect. In addition, the two baffles limit the scraper to prevent the scraper from getting stuck in the guide chute.
[0015] Preferably, the shell is provided with a stirring structure, which mainly consists of a stirring shaft. The stirring shaft is disposed on the shell, and two stirring rods are fixedly connected to the stirring shaft.
[0016] The effect achieved by the above components is that rotating the stirring shaft can drive the two stirring rods to stir the tea leaves, thereby improving the stir-frying effect.
[0017] Preferably, a sleeve is rotatably connected to the frame, the sleeve is fixedly connected to the stir-frying drum, the sleeve is rotatably sleeved on the stirring shaft, a first bevel gear is fixedly connected to the sleeve, a second bevel gear is fixedly connected to the stirring shaft, a connecting rod is fixedly connected to the housing, and one end of the connecting rod is rotatably connected to a third pawl through a bearing, the third pawl meshing with the first bevel gear and the third pawl meshing with the second bevel gear.
[0018] The effect achieved by the above components is that rotating the stirring shaft can drive the second bevel gear to rotate, which in turn drives the third spur gear to rotate, and further causes the sleeve to drive the first bevel gear to rotate in the opposite direction.
[0019] Preferably, a motor is fixedly connected to the housing, and the stirring shaft is driven to rotate by the motor.
[0020] The effect achieved by the above components is as follows: the output end of the motor is connected to the stirring shaft through a reducer and a coupling. The motor model is 28BYJ-48. First, the power is turned on to power the motor control system, and then the motor is started to drive the stirring shaft to rotate.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting a sieving structure, tea leaves are put into the frying drum, biomass pellet fuel is added to the heating chamber, and the drum is heated by ignition. The frying drum is rotated, causing the tea leaves to tumble. The smoke is discharged through the exhaust pipe. During the frying process, as the tea leaves are tumbled with the rotation of the frying drum, smaller particles and debris will be discharged through several sieve holes into the fixed drum. No additional sieving operation is required, thus avoiding the current practice of adding a screening process to remove these debris after frying. The additional screening process increases the complexity of the processing flow, time costs, and labor costs. Attached Figure Description

[0030] Example 1, as Figure 1 and Figure 2 The present invention relates to a tea processing stir-frying device, comprising a frame 1, a housing 2 fixedly connected to the frame 1, a stir-frying cylinder 5 rotatably connected to the housing 2, a heating chamber 3 fixedly connected to the housing 2, and an exhaust pipe 4 fixedly connected to the housing 2.
[0031] Reference Figures 1 to 6The frying drum 5 is equipped with a sieving structure 6, which mainly consists of several sieve holes 61. All sieve holes 61 are formed on the frying drum 5. A fixed cylinder 62 is fixedly connected to the shell 2 and fitted onto the outside of the frying drum 5. Tea leaves are added to the frying drum 5, and biomass pellet fuel is added to the heating chamber 3 and ignited to heat the frying drum 5. Rotating the frying drum 5 causes the tea leaves to tumble, and the smoke is discharged through the exhaust pipe 4. During the frying process, smaller particles and debris pass through the sieve holes 61. The material is discharged into the fixed cylinder 62 without the need for additional sieving, thus avoiding the current practice of adding a sieving process after stir-frying to remove these debris. This additional sieving process increases the complexity, time, and labor costs of the processing. A discharge pipe 63 is fixedly inserted into the heating chamber 3, and a guide groove 64 is formed on the inner wall of the fixed cylinder 62. The guide groove 64 is connected to the discharge pipe 63. After entering the fixed cylinder 62, debris and other materials flow along the inner wall of the fixed cylinder 62 into the guide groove 64. Because the guide groove 64 is close to... One end of the discharge pipe 63 is lower than the other, so the debris will enter the discharge pipe 63 along the guide chute 64 and then be discharged. Two fixed blocks 65 are fixedly connected to the frying drum 5, and scrapers 68 are provided on both fixed blocks 65. When the frying drum 5 rotates, it will drive the scrapers 68 to move, so that the scrapers 68 clean the inner wall of the fixed cylinder 62 and prevent them from sticking to the inner wall of the fixed cylinder 62. The fixed blocks 65 are provided with sliding grooves 66, and sliding rods 67 are slidably connected in the sliding grooves 66. The sliding rods 67 are fixedly connected to the scrapers 68. The sliding rod 67 drives the scraper 68 to move, thereby adjusting the position of the sliding rod 67. A spring 610 is fixedly connected to the inner wall of the slide groove 66. One end of the spring 610 is fixedly connected to the sliding rod 67. Two baffles 69 are fixedly connected in the guide groove 64. When the scraper 68 is in contact with the inner wall of the fixed cylinder 62, the spring 610 is in a contracted state. Therefore, the rebound force of the spring 610 acts on the sliding rod 67, resulting in a better cleaning effect. The two baffles 69 limit the scraper 68 to prevent the scraper 68 from getting stuck in the guide groove 64.
[0032] Reference Figure 2 and Figure 4The housing 2 is equipped with a stirring structure 7, which mainly consists of a stirring shaft 71. The stirring shaft 71 is mounted on the housing 2, and two stirring rods 72 are fixedly connected to the stirring shaft 71. Rotating the stirring shaft 71 can drive the two stirring rods 72 to stir the tea leaves, improving the stir-frying effect. A sleeve 73 is rotatably connected to the frame 1, and the sleeve 73 is fixedly connected to the frying cylinder 5. The sleeve 73 is rotatably mounted on the stirring shaft 71, and a first bevel gear 74 is fixedly connected to the sleeve 73. A second bevel gear 75 is fixedly connected to the stirring shaft 71. A connecting rod 77 is fixedly connected to the housing 2, and one end of the connecting rod 77 is rotatably connected to a third bevel gear through a bearing. The third bevel gear 76 is meshed with the first bevel gear 74, and the third bevel gear 76 is meshed with the second bevel gear 75. Rotating the stirring shaft 71 can drive the second bevel gear 75 to rotate, which in turn drives the third bevel gear 76 to rotate, further causing the sleeve 73 to drive the first bevel gear 74 to rotate in the opposite direction. A motor 78 is fixedly connected to the housing 2. The stirring shaft 71 is driven to rotate by the motor 78. The output end of the motor 78 is connected to the stirring shaft 71 through a reducer and a coupling. The model of the motor 78 is 28BYJ-48. First, the power is turned on to power the motor 78 control system, and then the motor 78 is started to drive the stirring shaft 71 to rotate.
[0033] The working principle is as follows: Tea leaves are placed into the frying drum 5, and biomass pellet fuel is added to the heating chamber 3 and ignited to heat the frying drum 5. Rotating the frying drum 5 causes the tea leaves to tumble, and the smoke is discharged through the exhaust pipe 4. During the frying process, smaller particles and debris pass through several sieve holes 61 and enter the fixed drum 62, eliminating the need for additional sieving. This avoids the current practice of adding a sieving process after frying to remove these debris, which increases the complexity, time, and labor costs of the processing. After entering the fixed drum 62, the debris flows along the inner wall of the fixed drum 62 into the guide trough 64. Since the end of the guide trough 64 closest to the discharge pipe 63 is lower than the other side, the debris flows along the guide trough 64 into the discharge pipe 63 and is then discharged. The rotation of the frying drum 5 drives the scraper 68 to move, causing the scraper 68 to scrape against the inner wall of the fixed drum 62. To clean and prevent the tea leaves from sticking to the inner wall of the fixed cylinder 62, the sliding rod 67 moves the scraper 68 to adjust its position. When the scraper 68 is in contact with the inner wall of the fixed cylinder 62, the spring 610 is in a contracted state. Therefore, the rebound force of the spring 610 acts on the sliding rod 67, resulting in a better cleaning effect. The two baffles 69 limit the scraper 68 to prevent it from getting stuck in the guide trough 64. Rotating the stirring shaft 71 can drive the two stirring rods 72 to stir the tea leaves, improving the stir-frying effect. Rotating the stirring shaft 71 can drive the second bevel gear 75 to rotate, which in turn drives the third pawl wheel 76 to rotate, further causing the sleeve 73 to drive the first bevel gear 74 to rotate in the opposite direction. The output end of the motor 78 is connected to the stirring shaft 71 through a reducer and a coupling. The model of the motor 78 is 28BYJ-48. First, the power is turned on to power the motor 78 control system, and then the motor 78 is started to drive the stirring shaft 71 to rotate.
