Description

Technical Field

[0001] This utility model belongs to the field of tea technology, and relates to high-voltage pulse electric fields, specifically a device for processing tea using high-voltage pulse electric fields. Background Technology

[0002] High-voltage pulsed electric field (HPP) treatment of tea is an advanced food processing technology designed to improve the quality and safety of tea. This device applies brief, intense electric field pulses to increase the permeability of tea cell membranes, thereby effectively enhancing the extraction efficiency of active ingredients. This treatment method not only preserves the natural flavor and nutrients of tea but also significantly reduces the content of harmful microorganisms, extending the product's shelf life. Furthermore, the HPP treatment process is relatively gentle, minimizing the loss of heat-sensitive components, and has therefore attracted increasing attention and application from tea producers.

[0003] However, some existing high-voltage pulse electric field tea processing devices may have uneven electric field distribution during use, resulting in higher electric field strength in some areas than in others. This leads to different processing effects on the tea leaves at different locations, and therefore, this problem needs to be solved. Utility Model Content

The technical problem this invention aims to solve is that, because the distribution of the electric field may be uneven, the electric field strength in some areas may be higher than in other areas, resulting in different treatment effects on the tea leaves at different locations.

[0012] 1. This utility model employs a technique of using scrapers to agitate the tea leaves, thus avoiding uneven processing. It effectively solves the problem of uneven electric field distribution, where some areas may have higher electric field strength than others, leading to varying processing effects on the tea leaves.

[0020] Reference Figure 1 - Figure 5 A high-voltage pulsed electric field processing device for tea includes a base 1. Two support frames 101 are symmetrically fixedly connected to the top of the base 1. A pulse chamber 102 is rotatably connected between the two support frames 101.

A rotating mechanism for rotating the guide rollers 3 is provided at one end of each of the three guide rollers 3. The scrapers 304 prevent uneven processing of the tea leaves.

[0021] Preferably, the moving mechanism includes a reciprocating lead screw 201, which is rotatably connected to one side of the base 1. A first motor 2 is fixedly connected to one end of the reciprocating lead screw 201, and the first motor 2 is fixedly connected to one side of the base 1. A slider 202 is slidably sleeved on the surface of the reciprocating lead screw 201. A lead screw sleeve 203 is provided inside the slider 202 near the reciprocating lead screw 201, and the lead screw sleeve 203 and the reciprocating lead screw 201 are mutually cooperated. Two limiting plates 204 are symmetrically fixedly connected to the top of the slider 202. An adjusting plate 205 is slidably sleeved on the surface of the two limiting plates 204. The setting of the limiting plates 204 can ensure that the adjusting plate 205 can also move upward during the movement. Both ends of the adjusting plate 205 are provided with adjusting mechanisms for adjusting the adjusting plate 205. The setting of the reciprocating lead screw 201 can make the adjusting plate 205 move.

[0022] Furthermore, the adjustment mechanism includes an adjustment column 206, which is fixedly connected to one side of the adjustment plate 205. A sliding groove 103 is provided on the surface of the support frame 101 near the adjustment column 206. Adjustment grooves 104 are provided at both ends of the sliding groove 103. The sliding groove 103 and the adjustment groove 104 are interconnected. The adjustment column 206 is configured to cooperate with the sliding groove 103 and the adjustment groove 104. The adjustment plate 205 can be adjusted by the setting of the adjustment groove 104.

[0023] Preferably, the rotating mechanism includes a rotating shaft 405, which is fixedly connected to one end of the guide roller 3. A worm gear 406 is fixedly sleeved on the surface of the rotating shaft 405. A worm 404 is fitted on the surface of the worm gear 406. The worm 404 is rotatably connected to one side of the pulse chamber 102. A second motor 4 is fixedly connected to the surface of the pulse chamber 102 near the worm 404. A first synchronous pulley 401 is fixedly sleeved on the output shaft of the second motor 4. A second synchronous pulley 403 is fixedly sleeved on the surface of the worm 404 near the first synchronous pulley 401. The same synchronous belt 402 is sleeved on the surfaces of the first synchronous pulley 401 and the second synchronous pulley 403. A starting mechanism for starting the air vent 306 is provided at the end of the guide roller 3 away from the rotating shaft 405. The guide roller 3 can be rotated by the worm gear 406.

[0024] Furthermore, the starting mechanism includes a flow guide box 301, which is fixedly connected to one side of the pulse chamber 102. A rotating shaft 303 is provided on the surface of the flow guide box 301 near the flow guide roller 3. The rotating shaft 303 is fixedly connected to one end of the flow guide roller 3. Two connecting pipes 302 are fixedly connected to the surface of the flow guide box 301 away from the pulse chamber 102.

[0025] Working principle: During use, the tea leaves to be processed are placed into the pulse chamber 102, and then the external air pump is connected to the connecting pipe 302. After preparation, the motor and air pump can be started via the controller. A synchronous belt 402 is installed on the output shaft of the second motor 4, and the other end of the synchronous belt 402 is connected to the worm gear 404. Therefore, when the second motor 4 starts, the worm gear 404 will rotate synchronously. Three guide rollers 3 are installed inside the pulse chamber 102, and two scrapers 304 are symmetrically fixed to the surface of each of the three guide rollers 3. A worm wheel 406 is installed at one end of each of the three guide rollers 3, and each of the three worm wheels 406 is connected to the worm gear 404. In coordination, when the worm gear 404 rotates, the worm wheel 406 drives the scraper 304 to rotate synchronously. Because the scraper 304 agitates the tea leaves during rotation, uneven processing is avoided. A guide box 301 is installed at one end of the guide roller 3, and the guide box 301 is connected to an external air pump via a connecting pipe 302. Therefore, when the guide roller 3 drives the scraper 304 to rotate, air is ejected from the air vents 306 on the surface of the scraper 304, ensuring more thorough displacement of the tea leaves. A reciprocating screw 201 is also installed at the bottom of the base 1, and the reciprocating screw 201 is connected to the first motor 2. Thus, when the first motor 2 rotates... After motor 2 starts, reciprocating screw 201 rotates synchronously. A slider 202 is provided on the surface of the reciprocating screw 201, and the slider 202 engages with the reciprocating screw 201 via a screw sleeve 203. A pin hole is provided radially on the inner circumference of the screw sleeve 203, and a crescent-shaped pin that engages with the reciprocating screw 201 is placed inside the pin hole. Thus, when the reciprocating screw 201 rotates, the slider 202 can move. An adjusting plate 205 is provided on the top of the slider 202, and the adjusting plate 205 is connected to the slider 202 via a limiting plate 204. Therefore, when the slider 202 moves, the adjusting plate 205 moves synchronously. An adjusting column 206 is also installed at the end. The adjusting column 206 cooperates with the sliding groove 103 and adjusting groove 104 on one side of the base 1. As the reciprocating screw 201 continues to rotate, the slider 202 will drive the adjusting column 206 into the adjusting groove 104. Because the adjusting groove 104 is inclined, when the adjusting column 206 enters the adjusting groove 104, it will drive the adjusting plate 205 to move upward. The adjusting plate 205 cooperates with the pulse chamber 102, and when it moves upward, it is at one end of the pulse chamber 102. Therefore, when it moves upward, it can make the pulse chamber 102 tilt at an angle, further avoiding uneven processing of tea leaves.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
