Description

Technical Field

[0001] The invention relates to the technical field of tea processing equipment, in particular to a device for automatically killing fresh tea leaves. Background Art

[0002] Tea leaf withering is a key step in the tea making process. Its main purposes are: to destroy the activity of enzymes in fresh leaves, prevent tea leaves from fermenting and turning red, and keep the tea leaves green; to emit a grassy smell and develop tea fragrance; to evaporate part of the water to soften the leaves, which is conducive to subsequent processing steps such as shaping. Common methods of withering tea leaves include stir-frying (frying in a pan to wither), which is often used in Longjing tea, where the leaves are stir-fried in an iron pan to wither; steaming tea leaves, which uses steam to wither the fresh leaves, such as some Japanese matcha production methods; baking tea leaves, which use hot air to wither the leaves; and sun-drying tea leaves, which rely on sunlight to wither the leaves. Some production methods of Yunnan Pu'er tea involve sun-drying. When the fresh tea leaves are withering, an automatic withering device is used to process them.

[0003] However, there are still some problems when using the existing automatic tea-withering device. If the tea leaves are inside the device, they will be heated unevenly, resulting in low efficiency in withering. At the same time, there are some impurities inside the fresh tea leaves that will mix with the tea leaves, making it inconvenient to screen and process them.

[0004] To this end, the invention provides a device for automatically killing fresh tea leaves. Summary of the invention

[0015] Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The automatic fresh tea leaf killing device is provided with a support plate. Since the slide bar is slidably connected to the inside of the lifting groove, the killing frame can be movably connected between the two support plates. First, the fresh tea leaves are placed in the killing frame, and the heater is started by the controller. The hot air generated enters the inside of the air outlet plate through the air guide pipe, so that the fresh tea leaves in the killing frame are killed. Then, the motor is started by the controller, so that the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the screw rod to rotate, so that the screw rod drives the ring to rotate. Since a limiting rod is fixedly connected to the top of the ring, and the top of the limiting rod is slidably connected to the inside of the moving groove, it can limit the ring outside the screw rod. At this time, the screw rod can drive the ring to move outside the screw rod, so that the screw rod drives the air outlet plate to move back and forth on the top of the killing frame, achieving a uniform heating effect, thereby improving the killing efficiency.

[0018] (2) The automatic fresh tea leaf withering device is provided with a withering frame. When the motor drives the rotating shaft to rotate, the rotating shaft can drive the squeezing ball on the outer side of the transmission rod to rotate. At this time, the squeezing ball can intermittently squeeze the force cover on the top of the withering frame, so that the withering frame can move up and down between the support plates under the cooperation of the sliding rod and the return spring. A filtering hole is opened in the inner bottom wall of the withering frame, so that impurities inside the fresh tea leaves can be filtered into the inside of the collecting frame. After the processing is completed, the moving rod is moved inside the movable tube, so that the moving rod drives the clamping block to move out of the inside of the positioning groove. At this time, the collecting frame can be turned over under the action of the rotating rod, so as to clean the impurities inside the collecting frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] It should be noted that: the slide bar 4 is moved inside the lifting groove 3, so that the slide bar 4 drives the finishing frame 5 to move up and down between the two support plates 1. Since the return spring 6 is fixedly connected to the bottom of the slide bar 4, the finishing frame 5 can return to its original position when not subjected to external force. By starting the motor 14, the motor 14 drives the screw rod 16 to rotate on the inner side of the gantry 10. When the top of the limit rod 18 is slidably connected to the inside of the moving groove 19, the ring 17 on the outside of the screw rod 16 can be limited. The rotation of the rotating shaft 15 drives the extrusion ball 21 on the outside of the transmission rod 20 to rotate, thereby intermittently squeezing the force cover 9 on the top of the connecting plate 24.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] Working principle: by setting the support plate 1, since the slide bar 4 is slidably connected to the inside of the lifting groove 3, the withering frame 5 can be movably connected between the two support plates 1, firstly, the fresh tea leaves are placed in the withering frame 5, and the heater 11 is started by the controller 2, and the hot air generated enters the inside of the air outlet plate 13 through the air guide pipe 12, so that the fresh tea leaves in the withering frame 5 are withered, and then the motor 14 is started by the controller 2, so that the motor 14 drives the rotating shaft 15 to rotate, and the rotation of the rotating shaft 15 drives the screw rod 16 to rotate, so that the screw rod 16 drives the ring 17 to rotate, because the limit rod 18 is fixedly connected to the top of the ring 17, and the top of the limit rod 18 is slidably connected to the inside of the moving groove 19, so that the ring 17 outside the screw rod 16 can be limited, and at this time the screw rod 16 can drive the ring 17 to move outside the screw rod 16, so that the The rod 16 drives the air outlet plate 13 to move back and forth on the top of the withering frame 5, achieving the effect of uniform heating, thereby improving the withering efficiency. By setting the withering frame 5, when the motor 14 drives the rotating shaft 15 to rotate, the rotating shaft 15 can drive the squeezing ball 21 on the outside of the transmission rod 20 to rotate. At this time, the squeezing ball 21 can intermittently squeeze the force-bearing cover 9 on the top of the withering frame 5, so that the withering frame 5 moves up and down between the support plates 1 under the cooperation of the slide bar 4 and the return spring 6, and a filtering hole 7 is opened in the inner bottom wall of the withering frame 5, so that the impurities inside the fresh tea leaves can be screened into the inside of the collecting frame 23. When the processing is completed, the moving rod 26 is moved inside the movable tube 25, so that the moving rod 26 drives the clamping block 28 to move out of the inside of the positioning groove 29.
