Description

Technical Field

[0001] This utility model belongs to the field of tea sorting and stir-frying technology, specifically relating to a tea sorting and stir-frying device. Background Technology

[0002] In tea processing, electricity, gas, or hot air are typically used as heat sources. Precise temperature control of the equipment can deactivate enzymes in fresh leaves, causing them to evaporate moisture or release aroma. During the stir-frying process, rollers, stirrers, and other structures move the tea leaves, ensuring that each leaf is evenly exposed to the heat source, preventing localized scorching or under-processing. This also aids in shaping. High-temperature, rapid turning is used during fixation, low-temperature, slow turning during drying, and medium-temperature, gentle turning during aroma enhancement, ultimately achieving the desired color, aroma, flavor, and shape for the tea.

[0003] However, during tea processing, if ungraded tea leaves are directly put into the stir-frying stage, the tender buds and coarse old leaves have different heat requirements, which can easily lead to problems such as scorched tender leaves and undercooked old leaves. If the tea leaves after being screened by the equipment are transferred to the stir-frying equipment, the tea leaves are easily affected by moisture or impurities during the transfer process, which will affect the quality of the tea leaves in the subsequent stir-frying. Utility Model Content

[0004] The purpose of this utility model is to provide a tea screening and frying device to solve the above problems. The connecting plate drives the push rod to slide in the feeding hopper, so that the push rod can drive the sliding basket to slide back and forth in the feeding hopper. The screen installed at the bottom of the sliding basket can slide and screen the tea in the feeding hopper, so that the tea can be screened through the screen before frying.

[0005] This utility model achieves the above objectives through the following technical solutions: A tea sorting and stir-frying device includes a frame, a drive mechanism fixedly mounted on the frame, a connecting plate mounted on the drive mechanism, a sorting mechanism fixedly mounted on the connecting plate, and the sorting mechanism fixed to the top of the frame.

The screen 504 is connected to the inside of the feeding hopper 502. Both the feeding hopper 502 and the sliding basket 503 are designed with an inclined structure.

[0019] Please see Figures 1 to 6 As shown, the drive mechanism 3 includes a fixed frame 301 and a motor 302. The fixed frame 301 is fixedly installed on the side of the frame 1 near the connecting plate 4. The motor 302 is fixedly installed on the fixed frame 301. The output shaft of the motor 302 is fixedly connected to a turntable 303. A locking rod 304 is fixedly installed on the top of the turntable 303. The locking rod 304 is sleeved inside the connecting plate 4. When the control switch of the motor 302 is turned on, the motor 302 is fixed to the bottom end of the fixed frame 301 installed on the frame 1. The output shaft of machine 302 drives turntable 303 to rotate on fixed frame 301. A locking rod 304 is fixed on the top of turntable 303. The rotation of turntable 303 causes locking rod 304 to slide in the locking groove 305 provided in connecting plate 4. Locking rod 304 abuts against the inner wall of connecting plate 4, which can push connecting plate 4 to perform reciprocating linear motion. The connecting plate 4 is provided with locking groove 305, and locking rod 304 is slidably installed in the locking groove 305. The minimum diameter of locking rod 304 is equal to the width of locking groove 305.

[0020] Please see Figures 1 to 6As shown, a stirring mechanism 2 is installed near the bottom of the feeding hopper 502 on the frame 1. The stirring mechanism 2 includes a long rod 201 and a material box 202. The material box 202 is fixedly installed on the frame 1, and the long rod 201 is rotatably installed inside the material box 202. Both ends of the long rod 201 are fixedly connected to brackets 204. A pressure plate 205 and a stirring rod 206 are fixedly installed on the brackets 204 respectively. The brackets 204 at both ends of the long rod 201 drive the pressure plate 205 and the stirring rod 206 to move synchronously. The stirring rod 206 rotates with the long rod 201. The tea leaves at the bottom of the material box 202 are turned upwards to prevent local accumulation. The arc-shaped structure of the pressure plate 205 can apply slight pressure to the tea leaves as the support 204 rotates, simulating manual pressing and helping to shape the tea leaves. The part of the pressure plate 205 near the inner wall of the material box 202 is set with an arc-shaped structure. The pressure plate 205 and the stirring rod 206 are rotatably connected to the material box 202. A sealing plate 203 is slidably installed on the side wall of the material box 202. A feeding trough 207 is provided in the part of the material box 202 near the sealing plate 203.

[0021] In use, the operator first slowly pours the tea leaves to be screened into the hopper 502. The tea leaves slide down the inclined surface of the inner wall of the hopper 502 and fall into the sliding basket 503 installed inside the hopper 502. Since baffles 505 are installed at both ends of the hopper 502 near the sliding basket 503, the baffles 505 can block the part of the sliding basket 503 that is not in contact with the hopper 502, thus preventing the tea leaves from falling directly into the material box 202 from the gap between the hopper 502 and the sliding basket 503. Furthermore, a screen 504 is fixedly installed at the bottom of the sliding basket 503, and the inclined structure of the hopper 502 can guide the tea leaves to converge towards the center of the screen 504. When screening tea leaves, the control switch of motor 302 can be turned on. Motor 302 is fixed to the bottom of the mounting bracket 301 on the frame 1. The output shaft of motor 302 drives turntable 303 to rotate on the mounting bracket 301. A locking rod 304 is fixed to the top of turntable 303. The rotation of turntable 303 causes locking rod 304 to slide in the locking groove 305 provided in connecting plate 4. Locking rod 304 abuts against the inner wall of connecting plate 4, which can push connecting plate 4 to make reciprocating linear motion. The end of connecting plate 4 is connected to a push rod 501. A fixed connection is established, with push rod 501 driving the sliding basket 503 to reciprocate synchronously within the feeding hopper 502. The screen 504 within the sliding basket 503 can shake and screen the tea leaves. Qualified tea leaves, after screening, fall through the screen 504 into the conveying channel at the bottom of the feeding hopper 502, allowing them to be directly discharged into the material box 202. Impurities mixed in with the tea leaves are trapped on the surface of the screen 504 and cleaned after screening. Once the tea leaves fall into the material box 202, a long rod 201 is rotatably installed within it. The long rod 201 rotates under the drive, and the supports 204 at both ends of the long rod 201 drive the pressure plate 205 and the stirring rod 206 to move synchronously. The stirring rod 206 rotates with the long rod 201, turning the tea leaves at the bottom of the material box 202 upward to prevent local accumulation of tea leaves. The arc-shaped structure of the pressure plate 205 rotates with the support 204 to apply slight pressure to the tea leaves, simulating manual pressing action and helping to shape the tea leaves. During the stir-frying process, the temperature of the material box 202 is maintained, and the color of the tea leaves is checked to avoid over-drying and causing the tea leaves to become brittle. After the stir-frying is completed... Turn off the heating system and keep the long rod 201 rotating to prevent the tea leaves from scorching due to residual heat. Then push the sealing plate 203, which is slidably installed on the side wall of the material box 202. The sealing plate 203 slides along the slide rail set inside the material box 202, so that the feeding trough 207 on the side wall of the material box 202 is in an open state. The tea leaves are discharged along the feeding trough 207 under the push of the pressure plate 205 and the stirring rod 206. During the discharge process, the tea leaves are collected by a collection container. If continuous processing is required, the feeding trough 207 can be connected to a belt conveyor to realize automated discharge.
