Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically to a drying and screening device for tea processing. Background Technology

[0002] Tea leaves, commonly known as tea, generally include the leaves and buds of the tea plant. Other names include tea, jia, ming, and chuan. Tea contains catechins, cholesterol, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. Tea beverages are one of the world's three major beverages. In the tea production process, the tea leaves often need to be dried. However, after drying, the tea leaves will carry some impurities, so it is necessary to screen the dried tea leaves.

[0003] In the existing technology, after drying the tea leaves using a single drying device, the dried tea leaves are then screened manually or by other screening equipment. This results in poor screening effect and low drying and screening efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that drying tea leaves separately and then manually or mechanically sorting them results in poor sorting effect and low efficiency.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A drying and screening device for tea processing includes a main body and a screening mechanism connected to the main body. The screening mechanism includes a first motor and a screening cylinder. The screening cylinder is fixed inside the main body and has several screening holes. The first motor is fixed to the outside of the main body, and a connecting shaft is fixed to the output end of the first motor. The connecting shaft is rotatably connected to the screening cylinder inside the main body. A spiral conveyor plate is fixed to the connecting shaft and is rotatably disposed inside the screening cylinder.

[0007] Furthermore, the outer circumference of the spiral conveyor plate rotates and fits against the inner wall of the screening cylinder.

[0009] Furthermore, the feed hopper and the first discharge hopper are arranged in a centrally symmetrical manner.

[0010] Furthermore, the lower end of the main body is provided with a first discharge port, a filter screen is fixedly connected to the first discharge port, and a second discharge hopper is fixedly connected to the lower end of the main body, the second discharge hopper being connected to the first discharge port.

[0011] Furthermore, a pushing component is connected to the main body. The pushing component includes a second motor and a push plate. The second motor is fixed to the outside of the main body, and a screw is fixed to the output end of the second motor. The main body is symmetrically provided with sliding grooves. The screw is rotatably connected to one side of the sliding groove inside the main body, and a slide rod is fixed to the other side of the sliding groove inside the main body. Slider blocks are fixed to both ends of the push plate. The sliders are slidably connected to the sliding grooves. One end of the push plate slider is threadedly connected to the screw, and the other end of the push plate slider is slidably connected to the slide rod. The lower end of the push plate is slidably attached to the filter screen.

[0012] Furthermore, a second discharge port is provided on the outer side of the main body, the second discharge port is flush with the filter screen, and a third discharge hopper is fixedly connected to the outer side of the main body at the second discharge port.

[0026] like Figure 1-6 As shown, a drying and screening device for tea processing includes a main body 1 and a screening mechanism 4. The screening mechanism 4 is connected to the main body 1 and includes a first motor 405 and a screening cylinder 401. The screening cylinder 401 is fixed inside the main body 1 and has a plurality of screening holes 404. The first motor 405 is fixed to the outside of the main body 1, and a connecting shaft 406 is fixed to the output end of the first motor 405. The connecting shaft 406 is rotatably connected to the screening cylinder 401 inside the main body 1. A spiral conveying plate 407 is fixed to the connecting shaft 406 and is rotatably disposed inside the screening cylinder 401. The outer circumference of the spiral conveying plate 407 rotates and fits against the inner wall of the screening cylinder 401, thereby driving the tea leaves to move, screen, and convey within the screening cylinder 401 through the rotation of the spiral conveying plate 407.

[0027] like Figure 3 As shown, the upper end of the screening cylinder 401 is fixedly connected to and connected to the feed hopper 402 for introducing tea leaves. The feed hopper 402 extends movably from the upper end of the main body 1. The lower end of the screening cylinder 401 is fixedly connected to and connected to the first discharge hopper 403. The first discharge hopper 403 extends movably from the lower end of the main body 1 for collecting the tea leaves obtained after screening by the screening cylinder 401. The feed hopper 402 and the first discharge hopper 403 are arranged in a centrally symmetrical manner.

[0028] like Figure 3 As shown, in order to further sieve the tea leaves sieved by the screening cylinder 401, the lower end of the main body 1 is provided with a first discharge port 105, a filter screen 106 is fixedly connected to the first discharge port 105, and a second discharge hopper 107 is fixedly connected to the lower end of the main body 1 for collecting the tea leaves sieved by the filter screen 106. The second discharge hopper 107 is connected to the first discharge port 105.

[0029] like Figure 4 , 6As shown, in order to push the tea leaves on the filter screen 106 and collect the tea leaves remaining on the filter screen 106 after sieving, a pushing component 3 is connected to the main body 1. The pushing component 3 includes a second motor 301 and a push plate 304. The second motor 301 is fixed to the outside of the main body 1, and a screw 302 is fixed to the output end of the second motor 301. The main body 1 is symmetrically provided with sliding grooves 108. The screw 302 is rotatably connected to one side of the sliding groove 108 inside the main body 1, and a sliding rod 303 is fixed to the other side of the sliding groove 108 inside the main body 1. The push plate 304 is fixed at both ends. A slider 305 is connected to the slide groove 108. One end of the push plate 304 is threadedly connected to the screw 302, and the other end is slidably connected to the slide rod 303. The lower end of the push plate 304 is slidably attached to the filter screen 106. A second discharge port 103 is provided on the outside of the main body 1. The second discharge port 103 is flush with the filter screen 106. A third discharge hopper 104 is fixedly connected to the outside of the main body 1 at the second discharge port 103 for collecting the tea leaves obtained after being screened by the filter screen 106.

[0030] like Figure 1 As shown, an electric heating plate is symmetrically fixed to the inner wall of the main body 1, and an air inlet pipe 101 and an air outlet pipe 102 are symmetrically connected to both sides of the main body 1. An air pump 2 is connected to both the air inlet pipe 101 and the air outlet pipe 102, thereby controlling the flow direction of the hot air in the main body 1 to be opposite to the movement direction of the tea leaves through the air pump 2.

[0031] In use, this invention heats the main body 1 using a heating plate 5. Air pumps 2 on the inlet pipe 101 and outlet pipe 102 control the airflow within the main body 1 from right to left, guiding tea leaves into the screening cylinder 401 from the left-side feed hopper 402. The output of the first motor 405 drives the connecting shaft 406 to rotate, which in turn drives the spiral conveyor plate 407 to rotate. The spiral conveyor plate 407 moves the tea leaves from left to right within the screening cylinder 401, creating convection currents with the hot airflow. This ensures thorough contact between the hot airflow and the tea leaves, promoting drying. The tea leaves then pass through several screening holes in the screening cylinder 401. The tea leaves are screened at 404 and collected by the first discharge hopper 403. The tea leaves screened through the screening holes 404 fall onto the filter screen 106 and are screened by the filter screen 106. The tea leaves screened through the filter screen 106 are collected by the second discharge hopper 107. The output end of the second motor 301 drives the screw 302 to rotate. At the same time, under the sliding limit action of the slide bar 303, the rotation of the screw 302 drives the push plate 304 to slide on the filter screen 106 through the linkage of the slider 305. This pushes the tea leaves screened on the filter screen 106 to the second discharge port 103 and is collected by the third discharge hopper 104, thus completing the drying and multi-stage screening of the tea leaves.

[0032] In summary: In this embodiment of the present invention, after the tea leaves are introduced into the screening cylinder 401 inside the main body 1 by the feeding hopper 402, they are screened by the screening cylinder 401 driven by the spiral conveyor plate 407, and then screened by the filter screen 106. This allows for multi-stage screening of the tea leaves. While the tea leaves are being screened in the main body 1, the main body 1 is heated by the heating plate 5, thereby achieving the drying of the tea leaves. Furthermore, the flow direction of the hot airflow inside the main body 1 is controlled by the air pipe and the air pump 2 to be opposite to the tea leaf conveying direction, thereby effectively promoting the drying effect and drying efficiency of the tea leaves.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
