Description

Technical Field

[0001] This invention relates to the field of herbal plant extraction equipment technology, and in particular to a high-purity beverage ingredient extraction equipment and extraction process. Background Technology

[0002] Extracts from herbs can be used as the main raw material for solid beverages. When extracting juice from herbs, an extraction device is required.

[0003] A search of Chinese invention patents revealed the following: Publication number CN115918829B, titled "A High-Efficiency Concentration and Extraction Device for Herbal Solid Beverages." This invention uses a rolling roller to crush herbal plants, and the crushed juice is filtered and enters a filter cylinder. Under the action of a baffle and a cylindrical plate on top, the juice undergoes sedimentation and purification within the filter cylinder. The piston rod slides back and forth, allowing the juice to enter a forming cylinder for concentration and shaping. Extracting juice through crushing reduces the amount of residue in the juice, while sedimentation within the filter cylinder further reduces the amount of residue, improving the purity of the juice.

[0004] However, in actual use, some problems still exist in the above and similar technical solutions: 1. When using the rolling crushing method, the crushed material residue is easy to adhere to the inner wall of the crushing chamber and the surface of the discharge structure. It is necessary to stop the machine for manual cleaning, which is a complicated operation process and affects the efficiency of continuous operation. 2. Existing filtration methods mostly rely on gravity for natural permeation, resulting in low filtration efficiency. They also lack pressure-driven mechanisms to assist filtration. Furthermore, the filters are usually built-in, requiring disassembly of the equipment for replacement, making maintenance inconvenient. 3. During the filtration process, filter residue gradually accumulates and thickens on the surface of the filter screen, leading to increased filtration resistance and decreased efficiency. Furthermore, the lack of a corresponding automatic cleaning structure necessitates manual intervention for removal. Summary of the Invention

[0015] The extraction process of the high-purity beverage component extraction equipment includes the following steps: S1. Plant materials are put into the feed inlet of the upper grinding disc. The material enters between the upper and lower grinding discs, driving the grinding shaft to rotate, which in turn drives the upper grinding disc to rotate, crushing the material into slurry. S2. Drive the extrusion cylinder to engage with the end cylinder, pushing the second piston to slide and extruding the slurry inside the extrusion cylinder. The slurry is contained between the second piston and the first piston. The slurry enters between the filter screen and the first piston through the second one-way valve. The slurry is filtered through the filter screen, pushing the second piston. The second piston pushes the first piston, causing the first piston to push the filter residue into the end cylinder, extruding the filter residue and expelling the remaining slurry. This pulls the second piston back to its original position, creating a negative pressure between the first and second pistons to replenish the slurry. S3. When the extrusion cylinder moves towards the end cylinder, it drives the unloading rod to swing horizontally. When the extrusion cylinder and the end cylinder separate, the unloading rod swings downward to scrape off the filter residue adhering to the outside of the filter screen.

[0016] Compared with the prior art, the present invention provides a high-purity beverage component extraction device, which has the following beneficial effects: 1. The material enters the space between the upper and lower grinding discs through the hopper and rotating pipe. The motor drives the grinding shaft and the upper grinding disc to rotate, crushing the material into slurry that flows into the collection box. The upper grinding disc drives the push plate to rotate, pushing the slurry into the material bucket. The liquid level sensor detects the liquid level in the material bucket. When it is about to be full, the electric valve is controlled to reduce the feeding speed, realizing the automated coordination of crushing and feeding, avoiding slurry overflow, and ensuring the continuous and stable crushing operation. At the same time, the use of grinding discs to crush effectively avoids the problem of filter residue remaining in the crushing tank, eliminating the need to clean the filter residue.

[0017] 2. The grinding shaft drives the notched disc to rotate via a gear set, causing the extrusion cylinder to connect and seal with the end cylinder. The connecting rod pushes the second piston, forcing the slurry through the second one-way valve into the space between the filter screen and the first piston for filtration. The second piston continues to advance, pressing against the first piston to completely expel the slurry. The filtrate is collected through the discharge pipe. Subsequently, the second piston retracts, and the first piston is limited by the baffle, creating a negative pressure between them. New slurry is drawn from the material tank through the first one-way valve. After the notched disc completes one revolution, the first spring resets the extrusion cylinder, exposing the filter screen, and the filter residue automatically falls off. Pressure-driven circulating filtration is used, which is highly efficient. The filter screen extends automatically, making it easy to replace, and maintenance does not require disassembly.

[0018] 3. When the extrusion cylinder moves towards the end cylinder, the push block pushes the control rod to slide, and through the guide groove and pin rod, it drives the unloading rod to swing to the horizontal. After the extrusion cylinder separates, the fourth spring pushes the control rod to reset, and drives the unloading rod to swing downward to scrape off the filter residue adhering to the outside of the filter screen, so that it falls into the discharge pipe and is discharged. Through mechanical linkage, stubborn filter residue is automatically cleaned, reducing filtration resistance. The working process is smooth, the failure rate is low, and there is no need to stop the machine to clean the filter screen. Attached Figure Description

A storage box 22 is installed at the connection between the lower grinding disc 29 and the upper grinding disc 25. The material is crushed by the lower grinding disc 29 and the upper grinding disc 25 to achieve slurry separation. The support frame 1 is equipped with a control host (not shown in the figure), which controls the operation of each component and enables the coordination of each component.

[0024] In this invention, a hopper 21 is installed at the top of the support 1 to facilitate the placement of materials. A rotating tube 23 is installed at the material inlet of the upper grinding disc 25. The top of the rotating tube 23 is rotatably connected to the bottom of the hopper 21. The bottom of the hopper 21 is coaxial with the grinding shaft 24. When the upper grinding disc 25 rotates, the rotating tube 23 can rotate with it to ensure the continuity of material feeding.

[0025] In this invention, a material bucket 27 is installed at the bottom of the storage box 22, which can temporarily store the slurry. The top end of the connecting pipe 41 is installed at the bottom of the material bucket 27, and the connecting pipe 41 is connected to the material bucket 27. The connecting pipe 41 is connected to the storage box 22 through the material bucket 27. A liquid level sensor 28 is installed on the material bucket 27, which can detect the amount of slurry in the material bucket 27. An electric valve 211 is installed at the bottom of the hopper 21. The feeding speed of the material is controlled by the cooperation of the liquid level sensor 28 and the electric valve 211.

[0026] In this invention, a push plate 210 is installed on the outer wall of the upper grinding disc 25. The push plate 210 is slidably connected to the inside of the storage box 22, so as to facilitate pushing the slurry to the material bucket 27 and making it easier for the material bucket 27 to collect the slurry.

[0027] In this invention, the grinding shaft 24 is rotatably connected to the bracket 1, and the bracket 1 is connected to the drive mechanism 3. The drive mechanism 3 includes a first gear 31. The bottom end of the grinding shaft 24 is keyed to the first gear 31. The bracket 1 is equipped with a motor 32. The output shaft of the motor 32 is keyed to a second gear 33. The first gear 31 and the second gear 33 mesh to facilitate driving the grinding shaft 24 to rotate, which in turn facilitates driving the upper grinding disc 25 to rotate.

[0028] Example 2: Based on Example 1, a high-purity beverage component extraction device is provided. A filter mechanism 4 is connected to a support 1. The filter mechanism 4 includes a squeezing cylinder 42. The squeezing cylinder 42 is slidably connected to the support 1. An end cylinder 48 for interlocking with the squeezing cylinder 42 is installed on the support 1. A filter screen 411 is slidably connected to one end of the end cylinder 48 near the squeezing cylinder 42. A second spring 413 connects the filter screen 411 and the squeezing cylinder 42. A discharge pipe 43 is installed on the squeezing cylinder 42. A first piston 410 and a second piston 415 are slidably connected inside the squeezing cylinder 42. A second one-way valve 414 is installed on the first piston 410. (It should be noted that both the second one-way valve 414 and the first one-way valve 415 are spring-loaded one-way valves. Their spring force is greater than the water pressure formed when the squeezing cylinder 42 is full of liquid, thereby ensuring that the slurry inside the squeezing cylinder 42 is discharged after the squeezing cylinder 42 is separated from the end cylinder 48.) The liquid will not be discharged directly from the second one-way valve 414. It needs to be pressured by the second piston 415 to open the second one-way valve 414. The first piston 410 is used to contact the filter screen 411. A connecting rod 418 is installed on one side of the first piston 410. The connecting rod 418 slides through the second piston 415. A third spring 419 is installed between the connecting rod 418 and the second piston 415. A baffle 417 is installed at the end of the extrusion cylinder 42 to contact the connecting rod 418. A connecting pipe 41 is installed between the first piston 410 and the second piston 415 in the extrusion cylinder 42. A first one-way valve 47 is installed on the connecting pipe 41. The connecting pipe 41 is connected to and communicates with the storage box 22. Thus, through the cooperation of the first piston 410 and the second piston 415, the slurry is extracted, filtered through the filter screen 411, and the filter residue is squeezed to fully discharge the slurry in the filter residue.

[0029] In this invention, a fourth gear 35 is keyed to the grinding shaft 24, a drive shaft 36 is rotatably connected to the bracket 1, a notched disc 44 is mounted on the drive shaft 36, a third gear 34 is keyed to the drive shaft 36, the fourth gear 35 meshes with the third gear 34, an abutment block 416 is installed at the end of the extrusion cylinder 42, the abutment block 416 is used to abut against the outer edge of the notched disc 44, an eccentric end rod 45 is rotatably connected to the bottom end of the notched disc 44, a connecting rod 46 is slidably fastened to the end rod 45, the connecting rod 46 is rotatably connected to the second piston 415, and a first spring 49 is connected between the extrusion cylinder 42 and the bracket 1, thereby facilitating the rotation of the notched disc 44.

[0030] In this invention, a sliding auxiliary mechanism 6 is connected to the bracket 1. The sliding auxiliary mechanism 6 includes a slide rod 61. The bracket 1 is equipped with slide rods 61 on both sides of the extrusion cylinder 42. A pair of fixing rings 62 are installed on the extrusion cylinder 42. The two ends of the fixing rings 62 are slidably connected to the pair of slide rods 61 respectively. A first spring 49 is movably sleeved on the slide rod 61. The two ends of the first spring 49 abut against the fixing rings 62 and the slide rod 61 respectively, ensuring the stability of the sliding of the extrusion cylinder 42.

[0031] Example 3: Based on Example 2, a high-purity beverage component extraction device is provided. A push-out mechanism 5 is connected to the support 1. The push-out mechanism 5 includes a control rod 53. The control rod 53 is connected to the support 1. A swinging unloading rod 55 is connected to the control rod 53. The filter residue adhering to the filter screen 411 can be scraped off by the swinging of the unloading rod 55.

[0032] In this invention, a mounting frame 52 is installed on the bracket 1, a control rod 53 is slidably connected to the mounting frame 52, a fourth spring 54 is installed between the control rod 53 and the mounting frame 52, a discharge rod 55 is rotatably connected to the mounting frame 52, and the discharge rod 55 is movably connected to the control rod 53. The control rod 53 is provided with a guide groove 56, the two ends of the guide groove 56 are straight, and the middle section is a quarter turn spiral. A pin 57 is installed on the discharge rod 55, and the end of the pin 57 extends into the guide groove 56. A push block 58 is installed on the outer wall of the extrusion cylinder 42, and the push block 58 is used to abut against the end of the control rod 53. An outlet pipe 51 is installed on the bracket 1 below the end cylinder 48. Through the cooperation of the pin 57 and the guide groove 56, it is easy to automatically drive the discharge rod 55 to swing and complete the automatic scraping of filter residue.

[0033] In this invention, an orifice plate 412 is slidably connected inside the end cylinder 48, and a filter screen 411 is threadedly screwed onto one side of the orifice plate 412. The two ends of the second spring 413 respectively abut against the end cylinder 48 and the orifice plate 412. The orifice plate 412 supports the filter screen 411 to prevent damage to the filter screen 411 when squeezing the filter residue. The threaded connection of the filter screen 411 to one side of the orifice plate 412 facilitates replacement.

[0034] An extraction process for a high-purity beverage component extraction device includes the following steps: S1. Plant material is put into the feed inlet of the upper grinding disc 25. The material enters between the upper grinding disc 25 and the lower grinding disc 29, driving the grinding shaft 24 to rotate, which in turn drives the upper grinding disc 25 to rotate, crushing the material into slurry. S2. Drive the extrusion cylinder 42 to engage with and abut against the end cylinder 48, pushing the second piston 415 to slide, thereby extruding the slurry inside the extrusion cylinder 42. The slurry is contained between the second piston 415 and the first piston 410. The slurry enters between the filter screen 411 and the first piston 410 through the second one-way valve 414. The slurry is filtered through the filter screen 411, pushing the second piston 415. The second piston 415 pushes the first piston 410, causing the first piston 410 to push the filter residue into the end cylinder 48, extruding the filter residue and expelling the remaining slurry. This pulls the second piston 415 back to its original position, creating a negative pressure between the first piston 410 and the second piston 415 to replenish the slurry. S3. When the extrusion cylinder 42 moves toward the end cylinder 48, it drives the unloading rod 55 to swing to the horizontal. When the extrusion cylinder 42 and the end cylinder 48 separate, the unloading rod 55 swings downward to scrape off the filter residue adhering to the outside of the filter screen 411.

[0035] Working principle: Plant materials are placed inside the hopper 21. The materials enter the feed inlet of the upper grinding disc 25 through the rotating tube 23, and enter between the upper grinding disc 25 and the lower grinding disc 29. The motor 32 is started, and the motor 32 drives the second gear 33 to rotate. The second gear 33 drives the first gear 31 to rotate, thereby driving the grinding shaft 24 to rotate, which in turn drives the upper grinding disc 25 to rotate, crushing the materials into slurry. The slurry flows into the collection box 22 for storage. When the upper grinding disc 25 rotates, it drives the push plate 210 to rotate, thereby pushing the slurry in the collection box 22 to move into the material bucket 27. The liquid level sensor 28 can detect the amount of slurry in the material bucket 27. When the material bucket 27 is about to be full, the electric valve 211 is controlled to work, reducing the feeding speed of the hopper 21, thereby ensuring the normal crushing process and preventing the slurry from filling the collection box 22 and overflowing. When the grinding shaft 24 rotates, it drives the fourth gear 35 to rotate, which in turn drives the third gear 34 to rotate, which in turn drives the drive shaft 36 to rotate, which in turn drives the notched disc 44 to rotate. When the notched disc 44 rotates, it drives the eccentric end rod 45 to rotate, pushing the end rod 45 to slide inward into the connecting rod 46. At this time, the notched end of the notched disc 44 will disengage from the abutting block 416. The complete outer edge of the notched disc 44 pushes the abutting block 416 to move, causing the extrusion cylinder 42 to slide. The fixing ring 62 slides along the slide rod 61, and the first spring 49 is compressed. The extrusion cylinder 42 will abut against the end of the end cylinder 48. A rubber pad is installed at the end of the extrusion cylinder 42 to ensure its airtightness when the extrusion cylinder 42 abuts against the end cylinder 48 and prevents leakage. After the abutment is completed, the end rod 45 will abut against the connecting rod 46. The connecting rod 46 is pushed to slide, which in turn pushes the second piston 415 to slide, thereby squeezing the slurry inside the extrusion cylinder 42. The slurry is located between the second piston 415 and the first piston 410. The slurry is sprayed out unidirectionally through the second one-way valve 414 and enters between the filter screen 411 and the first piston 410. When the second piston 415 slides, the third spring 419 is stretched, which pulls the connecting rod 418 to move, thereby pushing the first piston 410 towards the filter screen 411 and continuing to push the second piston 415. The second piston 415 will then come into contact with the first piston 410, thus completely extruding the slurry. All the slurry enters between the first piston 410 and the filter screen 411, where it is filtered. The filtrate then enters the filter screen 411. The filtrate is discharged through the discharge pipe 43 into the end cylinder 48. A collection bucket is connected to the discharge pipe 43 to collect high-purity filtrate. The second piston 415 is pushed, which in turn pushes the first piston 410, causing the first piston 410 to push the filter residue into the end cylinder 48. The filter residue pushes the filter screen 411 and the perforated plate 412 into the end cylinder 48. The second spring 413 is compressed, making the interior of the end cylinder 48 stepped. The perforated plate 412 and the stepped ends of the end cylinder 48 abut against each other, thus restricting the sliding of the perforated plate 412 and the movement of the filter screen 411. Under the push of the second piston 415, the first piston 410 extends into the end cylinder 48, squeezing the filter residue between the first piston 410 and the filter screen 411, ensuring the filtrate is fully discharged and preventing waste. At this point, connecting rod 46 has reached its maximum stroke, i.e., notch plate 44 rotates half a turn. The rotation of notch plate 44 pulls end rod 45, which slides away from connecting rod 46, thus releasing the push on filter screen 411. Second spring 413 will return to its original position and extend, pushing orifice plate 412 and filter screen 411 out and into the end of extrusion cylinder 42. This pushes first piston 410 and second piston 415 into extrusion cylinder 42. After end rod 45 slides away from connecting rod 46, it provides sliding allowance to connecting rod 46. Under the return contraction force of third spring 419, second piston 415 is pulled towards connecting rod 46. The sliding distance is limited by the sliding allowance of connecting rod 46. At this point, the end of connecting rod 418 will abut against baffle 417.This restricts the first piston 410 from sliding further into the extrusion cylinder 42. The notch plate 44 continues to move, pulling the end rod 45. After sliding a certain distance, the end rod 45 engages with the connecting rod 46, thereby pulling the connecting rod 46. The connecting rod 46 pulls the second piston 415, which moves away from the first piston 410. The first piston 410 is restricted from moving by the connecting rod 418 and the baffle 417. The third spring 419 contracts, creating a negative pressure between the first piston 410 and the second piston 415. Under the action of the first one-way valve 47, a negative pressure is created inside the connecting pipe 41, thereby drawing the slurry inside the material bucket 27 into the extrusion cylinder 42. After the notch plate 44 completes one revolution, the notch of the notch plate 44 rotates to the contact block 416. The notch plate 44 will no longer pull the end rod 45, but will push the end rod 45 to work. Under the action of the first spring 49, the first spring 49 returns to its original position and extends, pushing the extrusion cylinder 42 towards... The notch plate 44 slides in the direction of the end rod 45, which has completed its pulling action. There is a sliding allowance between the end rod 45 and the connecting rod 46. When the extrusion cylinder 42 slides, due to the friction between the second piston 415 and the first piston 410 and the extrusion cylinder 42, and the relatively low friction between the end rod 45 and the connecting rod 46, the extrusion cylinder 42 will drive the second piston 415 and the first piston 410, along with the slurry between them, to slide synchronously towards the notch plate 44. This causes the extrusion cylinder 42 to detach from the end cylinder 48, exposing the filter screen 411 and the adhered filter residue. The filter residue falls off under gravity, reducing the filtration resistance of the filter screen 411 and minimizing mechanical wear. Repeating these steps allows for continuous filtration, resulting in high-purity plant material filtered juice. The pressure injection method provides higher filtration efficiency, and the extended filter screen 411 facilitates replacement without disassembly. When the extrusion cylinder 42 moves toward the end cylinder 48, the extrusion cylinder 42 pushes the control rod 53 to slide through the push block 58, the fourth spring 54 is compressed, and the pin 57 slides along the guide groove 56. When it slides from the side guide groove 56 to the top, it will drive the unloading rod 55 to swing to the horizontal. This action is completed before the extrusion cylinder 42 and the end cylinder 48 are connected, so as to avoid the unloading rod 55 being damaged by impact. When the extrusion cylinder 42 and the end cylinder 48 are separated, after the extrusion cylinder 42 and the end cylinder 48 are separated, the fourth spring 54 pushes the control rod 53 to slide back to its original position, and drives the unloading rod 55 to swing downward through the pin 57. The unloading rod 55 scrapes off the filter residue adhering to the outside of the filter screen 411, so that it falls into the outlet pipe 51 and is discharged through the outlet pipe 51. The unloading rod 55 makes it easy to clean the filter residue that is tightly adhered and cannot fall off automatically. The mechanical linkage control is adopted, which has high smoothness and low failure rate.
