Description

Technical Field

[0001] This utility model relates to the field of black tea processing technology, specifically a powder separation device for black tea processing. Background Technology

[0002] The processing of black tea mainly involves withering, rolling, fermentation, and drying. The first step is withering, in which fresh leaves are spread out evenly to allow them to lose some moisture, soften, and release their grassy aroma, laying the foundation for subsequent processing.

[0003] Patent publication number "CN221890380U" discloses "A refined black tea powder separation device, which includes a box body with an inlet, an outlet, and an exhaust port. The inlet is located on the upper side of the box body, and the outlet is located on the lower side. An air guide plate and a filter screen are installed inside the box body. The upper and lower ends of the air guide plate and the filter screen are connected to the inlet and the outlet, respectively. The air guide plate, the filter screen, and the box body together form a channel for black tea to pass through. The side of the box body near the filter screen is a negative pressure chamber, and the side near the air guide plate is an air intake chamber. An exhaust port is provided in the negative pressure chamber of the box body. A fan is installed in the air intake chamber of the box body to inject air into the air intake chamber. When the black tea passes through the channel, the dust inside the black tea is blown out. After passing through the filter screen, the dust in the channel is discharged from the exhaust port, thereby effectively separating the dust inside the tea leaves."

[0004] In the aforementioned patent, black tea is fed into the feed inlet and the powder is removed by air separation. However, when adding black tea, the feed inlet is relatively large, making it difficult to control the amount of black tea added. When a large amount of black tea is added continuously, the overall thickness of the black tea is relatively thick. The black tea on the side away from the air outlet is blocked by the black tea in front, making it difficult to effectively remove the powder inside the black tea in this area.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0026] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figures 1 to 5 This application provides a powder separation device for black tea processing, including a main body box 1. A separation component 3 is provided on the outside of the main body box 1, and a feeding component 2 is provided on the top of the main body box 1. The feeding component 2 includes a feeding hopper 21, and two baffles 23 are slidably connected to the bottom of the feeding hopper 21. A connecting frame 22 is fixedly installed between the feeding hopper 21 and the top of the main body box 1. The two baffles 23 are symmetrical about the center of the main body box 1. The separation component 3 includes an outer block 31 and a gathering hopper 32. The outer block 31 is fixedly installed on the left side of the main body box 1, and the gathering hopper 32 is fixedly installed on the right side of the main body box 1. An air inlet 35 is opened inside the outer block 31. Ventilation holes 39 are opened on both the left and right side walls of the main body box 1. The air inlet 35 communicates with the inside of the main body box 1 through the ventilation holes 39, and the gathering hopper 32 communicates with the inside of the main body box 1 through the ventilation holes 39.

[0028] Side plates 24 are fixedly installed on both the front and rear sides of the feeding hopper 21. Slider 25s are fixedly installed on the top of both the front and rear ends of the baffle 23. The sliders 25 are slidably connected to the outer sides of the front and rear walls of the feeding hopper 21. A screw 26 is rotatably connected between the two front side plates 24, and the slider 25 is screwed through the two front sliders 25. A first motor 27 is fixedly installed on the outer end of the front side plate 24. The output end of the first motor 27 moves through the inside of the side plate 24 and is fixedly connected to the screw 26. The threads on both sides of the center of the screw 26 have different directions of rotation. The two sliders 25 are screwed to the outer sides of the threads with different directions of rotation of the screw 26, respectively. A slide rod 28 is fixedly installed between the two back side plates 24. The slide rod 28 moves through the two back sliders 25. The feeding hopper 21 is located directly above the main body box 1.

[0029] In this embodiment, when the black tea is being separated into powder, the black tea is placed inside the feeding hopper 21. At this time, the first motor 27 is started to drive the screw 26 to rotate. The rotation of the screw 26 drives the two sliders 25 on it to move synchronously in opposite directions, thereby driving the two baffles 23 below to move synchronously outward. The sliders 25 and the sliding rods 28 on the back ensure the stable movement of the baffles 23. By moving the baffles 23 to both sides, the tea leaves fall into the main body box 1 below through the gap between the two baffles 23 for air separation. The baffles 23 have adjustable distances so that the thickness of the black tea flow is similar to the gap between the baffles 23 when the black tea falls downward. Therefore, it can be ensured that the thickness of the black tea blown by the air is low during air separation, thereby ensuring better powder blowing out of the black tea and ensuring the powder separation effect. In addition, the width of the baffles 23 can be adjusted to accommodate black tea with different particle sizes, so that the black tea can pass through the baffles 23 normally and fall into the main body box 1.

[0030] Reference Figures 1 to 5 In one aspect of this embodiment, a bracket 36 is fixedly installed inside the air inlet 35, a fan 37 is rotatably connected to the right side of the bracket 36, and a second motor 38 is fixedly installed on the left side of the bracket 36. The output end of the second motor 38 movably passes through the inside of the bracket 36 and is fixedly connected to the fan 37.

[0031] The separating component 3 also includes an industrial vacuum cleaner 34. A connecting pipe 33 is fixedly installed on the right side of the collecting hopper 32, and the outer end of the connecting pipe 33 is fixedly installed at the inlet of the industrial vacuum cleaner 34. The collecting hopper 32 is connected to the industrial vacuum cleaner 34 through the connecting pipe 33. Support legs 4 are fixedly installed on the outer side of the main body box 1 and the outer block 31. A discharge hopper 5 is fixedly installed on the bottom of the main body box 1. The discharge hopper 5 is connected to the inside of the main body box 1 and is located inside the support legs 4.

[0032] In this embodiment, after the black tea falls into the main body box 1, the second motor 38 drives the fan 37 to rotate and blow air. The blown air enters the main body box 1 through the ventilation hole 39 on the left side and blows the black tea. The air can separate the powder inside the black tea from the tea. The powder passes through the ventilation hole 39 on the right side and enters the collection hopper 32 under the force of the air. After the powder enters the collection hopper 32, the industrial vacuum cleaner 34 generates suction and absorbs the powder that has entered the collection hopper 32 into the industrial vacuum cleaner 34 for storage through the connecting pipe 33. The sorted black tea falls into the discharge hopper 5 and is discharged through the discharge hopper 5 and collected by the external collection device, thereby realizing the rapid separation of black tea and powder.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working Principle: During the powder separation process, the black tea is placed inside the feeding hopper 21. The first motor 27 is then activated, driving the screw 26 to rotate. The screw 26's rotation causes the two sliders 25 on it to move synchronously in opposite directions, which in turn moves the two lower baffles 23 outwards. The sliders 25 and sliding rods 28 on the back ensure stable movement of the baffles 23. By moving the baffles 23 to the sides, the tea leaves fall through the gap between the two baffles 23 into the main body box 1 below for air separation. The adjustable distance of the baffles 23 ensures that the thickness of the black tea flow is similar to the gap between the baffles 23 as it falls downwards. This ensures that the thickness of the black tea blown by the air is relatively low, thus better separating the powder from the tea and guaranteeing effective powder separation. Furthermore, this method is suitable for black tea with different particle sizes. The width of the baffle 23 can also be adjusted so that the black tea can pass through the baffle 23 and fall into the main body box 1 normally. After the black tea falls into the main body box 1, the second motor 38 drives the fan 37 to rotate and blow air. The blown air enters the main body box 1 through the ventilation hole 39 on the left and blows the black tea. The air can separate the powder inside the black tea from the black tea. The powder passes through the ventilation hole 39 on the right and enters the collection hopper 32 with the force of the air. After the powder enters the collection hopper 32, the industrial vacuum cleaner 34 generates suction and absorbs the powder that has entered the collection hopper 32 into the industrial vacuum cleaner 34 for storage through the connecting pipe 33. The sorted black tea falls into the discharge hopper 5 and is discharged through the discharge hopper 5 and collected by the external collection device, thus realizing the rapid separation of black tea and powder.
