Description

Technical Field

[0001] The invention relates to the technical field of pharmaceuticals, in particular to pharmaceutical extraction equipment and an extraction method. Background Art

[0002] Medicinal materials play an important role in traditional Chinese medicine, health products and modern pharmaceuticals. The effective substances in their ingredients have significant benefits for human health. Different medicinal materials contain a variety of biologically active ingredients, such as polysaccharides, flavonoids, saponins, volatile oils, etc. These ingredients show unique effects in preventing and treating diseases, enhancing immunity, etc. Therefore, medicinal materials play an irreplaceable role in the pharmaceutical industry.

[0003] In the pharmaceutical process, the active ingredients in the medicinal materials need to be extracted before they can be fully utilized. The purpose of extraction is to separate the active substances in the medicinal materials so that they can function efficiently in the preparations. However, the direct use of unextracted medicinal materials often leads to problems such as low ingredient content and low absorption efficiency, which makes it difficult to ensure the efficacy of the medicine. Therefore, the extraction process is crucial in modern pharmaceutical manufacturing, which not only affects the efficacy of the product, but also determines the purity and quality of the drug.

[0004] There are many existing methods for extracting medicinal materials, including water extraction, alcohol extraction, ultrasonic extraction, and centrifugal extraction. Among them, centrifugal extraction is widely used in the extraction process. It uses centrifugal force to separate the juice and residue of the medicinal material, and can effectively extract the effective ingredients in the medicinal material. Compared with other extraction methods, centrifugal extraction has the advantages of simple operation and high efficiency, and is suitable for large-scale medicinal material extraction processes.

[0005] However, the existing centrifugal extraction method has certain shortcomings. In traditional centrifugal extraction, the crushed medicinal materials need to be carried or transferred many times before they can enter the centrifugal equipment for separation. This process not only wastes time, but also easily leads to secondary contamination of the medicinal materials, affects the purity of the extract, and reduces the extraction efficiency. The transfer steps during the operation increase the complexity of the equipment and the operating cost, which is not conducive to the simplification of the extraction process and the improvement of efficiency. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a pharmaceutical extraction device and an extraction method, which solves the problem in the prior art that the crushed medicinal materials need to be carried or transferred multiple times before entering the centrifugal equipment, thereby wasting time, causing secondary contamination of the medicinal materials, and affecting the extraction purity.

[0007] To achieve the above purpose, the present invention is implemented by the following technical scheme: a pharmaceutical extraction device, comprising: A crushing barrel, the top of which is provided with a second motor, which is used to drive the transmission shaft and the crushing knife to rotate and crush the raw materials after the medicinal materials are put into the crushing barrel; The extrusion barrel is located at the bottom of the crushing barrel and is hollowed out to receive the crushed raw materials. A pressing sheet is installed at the bottom of the transmission shaft to allow the raw materials to enter the extrusion barrel and rotate with the transmission shaft to squeeze the raw material juice. An extraction barrel is located below the crushing barrel. A centrifugal rack is arranged in the extraction barrel, and a screen is installed on the side wall of the centrifugal rack. The centrifugal rack is used to receive the raw material juice; Motor 1 is located at the bottom of the extraction barrel and is used to drive the centrifugal frame to rotate to generate centrifugal force, so that the juice passes through the screen into the extraction barrel, and the residue remains in the centrifugal frame.

[0008] Preferably, the crushing knife is provided with multiple layers, and the number of blades of the multiple layers of the crushing knife increases successively from top to bottom, a plurality of sieve plates are fixedly connected inside the extraction barrel, and the bottom surface of the crushing knife is in contact with the top surface of the sieve plate, and the apertures of the plurality of sieve plates decrease successively from top to bottom, and the cross-section of the sieve plate is set to be in a U shape.

[0009] Preferably, a bottom ring is fixedly connected to the bottom surface of the inner wall of the extraction barrel, and a slope is arranged on the top surface of the bottom ring. A base is fixedly connected to the middle of the bottom ring, and the bottom surface of the centrifugal frame contacts the top surface of the base.

[0010] Preferably, a discharge pipe is fixedly connected to the bottom of one side of the extraction barrel, a collecting barrel is threadedly connected to one side of the bottom surface of the extraction barrel, and the discharge pipe and the collecting barrel are both located on the lower side of the bottom ring.

[0011] Preferably, a retaining ring is fixedly connected to the top surface of the centrifugal frame, the cross section of the retaining ring is arranged in an inverted figure eight shape, and a baffle is fixedly connected to the side wall of the inner wall of the centrifugal frame.

[0012] Preferably, a boss is fixedly connected to the middle of the bottom surface of the inner wall of the centrifugal frame, a plug plate is fixedly connected to the outer side of the top of the output end of the motor 1, the plug plate is movably connected in the boss, and a nut 1 is threadedly connected to the top of the output end of the motor 1, and the nut 1 is located on the top surface of the boss.

[0013] Preferably, a support rod is fixedly connected to the top of the outer wall of the extraction barrel, a threaded rod is fixedly connected to the bottom of the support rod, a nut 2 is threadedly connected to the top of the threaded rod, and an ear plate is fixedly connected to the bottom of the outer wall of the crushing barrel, the threaded rod passes through the ear plate, and the bottom surface of the ear plate is in contact with the top surface of the support rod.

[0014] Preferably, a sleeve is fixedly connected to the bottom of the crushing barrel, the diameter of the sleeve is larger than the diameter of the extrusion barrel, and the extrusion barrel is located inside the sleeve, and a feed pipe is installed on one side of the top surface of the extraction barrel.

[0015] A pharmaceutical extraction method, the extraction method comprising the following steps: S1, put the medicinal materials to be extracted into the crushing barrel from the feed pipe and drive the second motor to drive the transmission shaft, crushing knife and tablet pressing to rotate, and the crushing knife crushes the medicinal materials; S2, the crushed medicinal materials fall down along the through holes of the sieve plate in sequence and finally enter the extrusion barrel, at which time the tablet press squeezes the crushed medicinal materials so that the juice falls into the centrifugal frame; S3, guiding the juice into the outer side of the middle of the centrifugal frame through the boss, and then driving the motor to drive the centrifugal frame and the screen to rotate, at this time, the juice rotates with the centrifugal frame and is thrown out along the through holes of the screen, while the residue in the juice is retained in the centrifugal frame; S4, using the extraction bucket to enclose the thrown juice, and guide it to flow to the bottom ring, and use the bottom ring to drain it to the discharge pipe; S5. At this time, the last remaining residue in the juice falls into the collection bucket by its own gravity, and finally the valve on the discharge pipe is opened to discharge the final obtained juice.

[0016] Preferably, remove nut 2 to remove the crushing barrel from above the extraction barrel, and then remove nut 1 to remove the centrifugal frame. At this time, the crushing barrel, the screen and the extraction barrel can be cleaned separately.

[0017] Working principle: When in use, first put the medicinal materials to be extracted into the crushing barrel from the feed pipe. At this time, the uppermost sieve plate will support the uncrushed medicinal materials. Then start the second motor, which drives the transmission shaft, crushing knives and pressing plate to rotate. At this time, the crushing knives fully crush the medicinal materials. The crushed medicinal materials will fall through the through holes on the uppermost sieve plate into the next layer of sieve plate. The diameter of the through holes on the next layer of sieve plate is smaller than that of the through holes on the upper layer of sieve plate, and the number of crushing knives on the next layer is also increasing. Therefore, the step-by-step crushing of the medicinal materials can be realized. And the cross-section of the sieve plate is set in a U shape, so that the medicinal materials can be guided to the top surface of the sieve plate, avoiding the phenomenon that the medicinal materials are located at the inner side wall of the extraction barrel and resulting in incomplete crushing. When the crushing is over, finally it will fall into the extrusion barrel. At this time, the pressing plate will rotate along with the transmission shaft. By the rotation of the pressing plate, extrusion force can be applied to the crushed medicinal materials, so that the juice flows into the centrifugal frame. And after the juice is discharged from the extrusion barrel, it will flow down along the inner wall of the sleeve. Therefore, the sleeve can be used to avoid the situation that the juice splashes out of the device due to excessive extrusion force. Subsequently, the juice enters the outer side of the middle part of the centrifugal frame through the guidance of the boss and flows to the bottom ring through the sieve mesh. And part of the residue will also enter the centrifugal frame. Therefore, by starting the first motor, the first motor drives the centrifugal frame and the sieve mesh to rotate at high speed. The centrifugal force throws the juice out through the holes of the sieve mesh, while the residue in the juice remains in the centrifugal frame. And the inclined surface of the bottom ring guides the discharged juice to the discharge pipe. Finally, the residue remaining in the juice will fall into the collection barrel due to gravity. Subsequently, the operator can open the valve on the discharge pipe to discharge the finally extracted pure juice. And by setting the retaining ring in an inverted V shape, the juice can be guided into the centrifugal frame, avoiding the situation that the juice directly enters the extraction barrel without filtration and is discharged from the discharge pipe. At the same time, when the centrifugal frame centrifuges the medicinal material juice, the movement of the juice is restricted by the baffle inside the centrifugal frame, avoiding the phenomenon of relative movement between the juice and the centrifugal frame, making the two in a relatively static state. Therefore, it is beneficial for the centrifugal force to act on the juice. At the same time, the retaining ring can also be used to enclose the juice and residue during centrifugation to avoid them flying out of the centrifugal frame. And after use, turn the second nut to remove it from the threaded rod. At this time, the crushing barrel can be lifted and removed from the support rod. Subsequently, the crushing barrel can be rinsed. Then rotate and remove the first nut. At this time, the retaining ring can be pulled to remove the centrifugal frame and the sieve mesh from the base. Subsequently, the sieve mesh can be rinsed. When the rinsing is over, first install the centrifugal frame. And when installing, insert the plug board into the boss, then tighten the first nut. Finally, place the crushing barrel, and make the threaded rod pass through the ear plate and reinstall the second nut.

[0018] The present invention provides an extraction device and an extraction method for pharmaceutical use. It has the following beneficial effects: 1. The present invention arranges the extraction barrel below the tablet crushing barrel, so that the crushed medicinal materials can directly enter the centrifugal extraction process without being transferred through other containers or steps, thereby avoiding the time delay caused by the transportation of the crushed medicinal materials and reducing the risk of secondary contamination, making the extraction process more efficient, significantly accelerating the extraction speed, and improving the overall work efficiency.

[0019] 2. The present invention sets a plurality of crushing knives and sieve plates. During the crushing process, the medicinal materials are first supported by the upper sieve plate and initially crushed. The through holes of the sieve plates gradually become smaller, and the number of crushing knives increases step by step, forming a step-by-step crushing mechanism, thereby achieving the effect of step-by-step screening and crushing, which can not only ensure that the medicinal materials are fully crushed, but also effectively control the fineness of the powder, ensure that the juice is released more fully in the subsequent extraction process, and improve the extraction rate.

[0020] 3. The present invention fixes nut 2 on the threaded rod, so that the operator can quickly remove the crushing barrel from the support rod, which is convenient for cleaning the crushing barrel. At the same time, nut 1 facilitates the disassembly of the centrifugal frame and the screen, which simplifies the cleaning process, not only shortens the cleaning time of the equipment, ensures the sanitary condition of the equipment, but also effectively improves the maintenance efficiency of the equipment.

[0021] 4. The present invention uses a baffle ring and a baffle plate. During the centrifugation process, the inverted eight-shaped baffle ring guides the juice into the centrifuge frame to prevent the juice from being discharged directly without being filtered. The baffle plate inside the centrifuge frame further limits the relative movement of the juice, so that the juice and the centrifuge frame remain in a relatively static state, ensuring that the centrifugal force fully acts on the juice, thereby effectively separating the residue and the juice. At the same time, the baffle ring can prevent the juice and the residue from flying out of the centrifuge frame due to the centrifugal force, thereby keeping the equipment clean and stable in operation.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please see attached Figure 1 -Attached Figure 8 The embodiment of the present invention provides a pharmaceutical extraction device, including: a crushing barrel 5, a motor 2 6 is arranged on the top of which, the motor 2 6 is used to drive the transmission shaft 7 and the crushing knife 8 to rotate and crush the raw materials after the medicinal materials are put into the crushing barrel 5; an extrusion barrel 11, which is located at the bottom of the crushing barrel 5 and is hollow, and is used to receive the crushed raw materials. A pressing tablet 10 is installed at the bottom of the transmission shaft 7, and is used for the raw materials to enter the extrusion barrel 11 and rotate with the transmission shaft 7 to extrude the raw material juice; an extraction barrel 1, which is located below the crushing barrel 5, and a centrifugal frame 3 is arranged in the extraction barrel 1, and a screen 4 is installed on its side wall, and the centrifugal frame 3 is used to receive the raw material juice; a motor 1 2, which is located at the bottom of the extraction barrel 1, and is used to drive the centrifugal frame 3 to rotate to generate centrifugal force, so that the juice passes through the screen 4 into the extraction barrel 1, and the residue remains in the centrifugal frame 3.

[0026] In the present invention, after the medicinal materials are put into the crushing barrel 5 through the feed port, the motor 2 6 is started, driving the internal transmission shaft 7 to rotate, and the transmission shaft 7 then drives the crushing knife 8 to rotate at high speed to crush the put-in medicinal materials. During the crushing process, after the medicinal materials are crushed, the powder and juice fall into the extrusion barrel 11 located at the bottom of the crushing barrel 5. The extrusion barrel 11 is a hollow design, which can effectively receive the crushed medicinal materials. A pressing tablet 10 is also installed at the bottom of the transmission shaft 7. After the crushed medicinal materials enter the extrusion barrel 11, the transmission shaft 7 continues to rotate to drive the pressing tablet 10, and the extrusion force generated by the rotation is used to further squeeze out the juice in the medicinal materials. The extrusion process enables the juice of the medicinal materials to be squeezed out more fully, providing efficient raw material juice for subsequent extraction. Through continuous crushing and extrusion, the process flow is simplified, and the loss and pollution of the intermediate links are avoided; Immediately afterwards, the squeezed juice flows into the extraction barrel 1 from the bottom of the extrusion barrel 11. After starting, it drives the centrifugal frame 3 to rotate at a high speed, generating centrifugal force. Using this powerful centrifugal force, the juice is separated through the screen 4. During the centrifugation process, the juice passes through the screen 4 and flows into the extraction barrel 1, while the solid residues are retained inside the centrifugal frame 3 by the centrifugal force, thus realizing the efficient separation of the juice and the residues. The centrifugal separation process further purifies the juice of the medicinal materials, ensuring that the finally obtained extract is more pure. Therefore, the continuous operation of crushing, juicing, and centrifugal extraction of the medicinal materials is realized, avoiding the time delay during the transfer of the crushed medicinal materials and reducing the secondary pollution caused by multiple handling, making the entire extraction process more concise and efficient, significantly improving the extraction speed, and effectively improving the overall work efficiency.

[0027] Please refer to the appendix Figure 6-Figure 8 , the crushing knives 8 are arranged in multiple layers, and the number of blades of the multiple layers of crushing knives 8 increases sequentially from top to bottom. A plurality of sieve plates 9 are fixedly connected inside the extraction barrel 1, and the bottom surface of the crushing knives 8 is in contact with the top surface of the sieve plates 9. The apertures of the plurality of sieve plates 9 decrease sequentially from top to bottom, and the cross-section of the sieve plate 9 is arranged in a U-shape.

[0028] In the present invention, the crushing knives 8 are arranged in a multi-layer structure, and the number of blades increases layer by layer from top to bottom, so that each layer of crushing knives 8 can accurately crush medicinal materials with different particle sizes. The upper crushing knives 8 are responsible for primary crushing, and the increase in the number of lower blades further strengthens the crushing effect, ensuring that the medicinal materials are gradually refined during the crushing process at different levels, laying a good foundation for the subsequent extraction process, and significantly improving the crushing efficiency and fineness control of the medicinal materials; In addition, a plurality of sieve plates 9 are fixedly connected inside the extraction barrel 1. The apertures of the sieve plates 9 decrease layer by layer from top to bottom, and the cross-section of each layer of sieve plate 9 is designed in a U-shape. Therefore, it can effectively guide the medicinal material powder to concentrate on the top surface of the sieve plate 9, avoiding the phenomenon that the powder slides down to the inner wall of the extraction barrel 1 and causes uneven crushing. The design of the gradually decreasing apertures of the sieve plates 9 enables larger particles of medicinal materials to be crushed on the upper sieve plates 9, while smaller particles can enter the next layer of sieve plates 9 through the through holes for more delicate crushing, thereby helping to crush the medicinal materials to the ideal fineness, ensuring the full release of the juice, and greatly improving the extraction efficiency and quality.

[0029] Please refer to the appendix Figure 1 and Figure 2 , the bottom surface of the inner wall of the extraction barrel 1 is fixedly connected with a bottom ring 12, and the top surface of the bottom ring 12 is provided with an inclined surface. The middle of the bottom ring 12 is fixedly connected with a base 13, and the bottom surface of the centrifugal frame 3 is in contact with the top surface of the base 13. One side of the bottom of the extraction barrel 1 is fixedly connected with a discharge pipe 14. One side of the bottom surface of the extraction barrel 1 is threadedly connected with a collection barrel 15, and both the discharge pipe 14 and the collection barrel 15 are located on the lower side of the bottom ring 12.

[0030] In the present invention, the top surface of the bottom ring 12 is provided with an inclined surface structure, which can effectively guide the flow of the juice after centrifugal separation, so that it can smoothly flow to the lower side of the bottom ring 12, avoiding the problem of juice retention or overflow. In addition, the middle part of the bottom ring 12 is fixedly connected with a base 13, and the top surface of the base 13 is in contact with the bottom surface of the centrifugal frame 3, providing a stable support for the centrifugal frame 3, ensuring that the centrifugal frame 3 remains stable during high-speed rotation without offset or vibration, which is conducive to the stability of the centrifugal effect and the improvement of the separation efficiency; The discharge pipe 14 and the collecting barrel 15 are both located on the lower side of the bottom ring 12. Through the drainage effect of the inclined surface of the bottom ring 12, the juice after centrifugal separation naturally flows into the discharge pipe 14 under the action of gravity, and then is discharged through the discharge pipe 14, reducing the need for manual operation. At the same time, the residue is discharged to the collecting barrel 15 through the discharge pipe 14, ensuring that the residue after extraction is effectively collected, facilitating subsequent processing, preventing cross contamination between the juice and the residue, and improving the purity of the extract and the cleanliness of the entire equipment.

[0031] Please see attached Figure 1-Figure 5 The top surface of the centrifugal frame 3 is fixedly connected with a retaining ring 16, and the cross section of the retaining ring 16 is set to an inverted eight-shaped shape. The side wall of the inner wall of the centrifugal frame 3 is fixedly connected with a retaining plate 17. The middle part of the bottom surface of the inner wall of the centrifugal frame 3 is fixedly connected with a boss 18, and the top outer side of the output end of the motor 2 is fixedly connected with a plug plate 19, and the plug plate 19 is movably connected in the boss 18, and the top of the output end of the motor 2 is threadedly connected with a nut 20, and the nut 20 is located on the top surface of the boss 18.

[0032] In the present invention, a retaining ring 16 with an inverted eight-shaped cross-section is fixedly connected to the top surface of the centrifugal frame 3, which can effectively guide the juice generated during the centrifugal process to flow into the centrifugal frame 3, prevent the juice from flowing out of the extraction barrel 1 without being filtered, and ensure that the juice enters the centrifugal frame 3 for sufficient centrifugal separation. The retaining ring 16 also plays a role of enclosure during high-speed centrifugation, preventing juice and residue from splashing out of the centrifugal frame 3 due to centrifugal force, thereby keeping the interior of the device clean; In addition, a baffle 17 is fixedly connected to the side wall of the inner wall of the centrifugal frame 3, which further limits the relative movement between the juice and the centrifugal frame 3 during the centrifugal process, keeps the juice and the centrifugal frame 3 in a relatively static state, and ensures that the centrifugal force can act more concentratedly on the juice, thereby achieving a more efficient separation effect and facilitating the complete separation of residue and juice; At the same time, a boss 18 is fixedly connected to the middle part of the bottom surface of the inner wall of the centrifugal frame 3, and an insert plate 19 is installed on the outer side of the top of the output end of the motor 2, and the insert plate 19 is movably connected in the boss 18, so as to ensure that the motor 2 can be firmly connected to the centrifugal frame 3 through the insert plate 19, and at the same time ensure the flexibility of disassembly and assembly of the centrifugal frame 3. In addition, a nut 20 is threadedly connected to the top of the output end of the motor 2, and the nut 20 is located above the top surface of the boss 18, providing an additional fixing effect, so that the centrifugal frame 3 remains stable during high-speed rotation. After removing the nut 20, the centrifugal frame 3 can be quickly disassembled and assembled, which is convenient for cleaning and maintenance of the equipment.

[0033] Please see attached Figure 1 and Figure 6 A support rod 21 is fixedly connected to the top of the outer wall of the extraction barrel 1, a threaded rod 22 is fixedly connected to the bottom of the support rod 21, a nut 24 is threadedly connected to the top of the threaded rod 22, and an ear plate 23 is fixedly connected to the bottom of the outer wall of the crushing barrel 5, the threaded rod 22 penetrates the ear plate 23, and the bottom surface of the ear plate 23 contacts the top surface of the support rod 21.

[0034] In the present invention, a support rod 21 is fixedly connected to the top of the outer wall, and a threaded rod 22 is connected to the bottom of the support rod 21, which is used to support and fix the structural stability of the crushing barrel 5. After removing the nut 24 on the top of the threaded rod 22, the crushing barrel 5 can be disassembled and reinstalled. By rotating the nut 24, the crushing barrel 5 on the threaded rod 22 can be easily loosened or fixed, which greatly improves the operating convenience of the equipment. The bottom of the outer wall of the crushing barrel 5 is also fixedly connected to an ear plate 23, and the bottom surface of the ear plate 23 is in contact with the top surface of the support rod 21, and the threaded rod 22 passes through the middle of the ear plate 23, thereby ensuring that the crushing barrel 5 can maintain a tight connection with the extraction barrel 1 during installation, and also providing additional support and stability to prevent the crushing barrel 5 from loosening or deviating during the operation of the equipment.

[0035] Please see attached Figure 1 , Figure 6 and Figure 7 A sleeve 26 is fixedly connected to the bottom of the crushing barrel 5 , the diameter of the sleeve 26 is larger than the diameter of the extrusion barrel 11 , and the extrusion barrel 11 is located in the sleeve 26 , and a feed pipe 25 is installed on one side of the top surface of the extraction barrel 1 .

[0036] In the present invention, the diameter of the sleeve 26 is slightly larger than that of the extrusion barrel 11, so that the extrusion barrel 11 can be located inside the sleeve 26. In this way, the crushed medicinal materials fall directly into the extrusion barrel 11 in the sleeve 26 after being pulverized, thereby avoiding the overflow or splashing of the crushed medicinal materials during the transfer process. The existence of the sleeve 26 also provides additional protection for the extrusion barrel 11, so that it remains stable during the extrusion operation, ensuring that the medicinal material juice can be smoothly collected in the centrifugal frame 3, avoiding the juice splashing out of the outside of the equipment due to excessive extrusion force, thereby improving the cleanliness and efficiency of the extraction; in addition, the feed pipe 25 is directly connected to the crushing barrel 5, so that the medicinal materials can quickly enter the pulverization process.

[0037] The pharmaceutical extraction method using the above device comprises the following steps: S1, put the medicinal materials to be extracted from the feed pipe 25 into the crushing barrel 5 and drive the motor 2 6 to drive the transmission shaft 7, the crushing knife 8 and the tableting 10 to rotate, and the crushing knife 8 crushes the medicinal materials; S2, the crushed medicinal materials fall down along the through holes of the sieve plate 9 and finally enter the extrusion barrel 11, at which time the tablet press 10 squeezes the crushed medicinal materials so that the juice falls into the centrifugal frame 3; S3, the juice is guided into the outer middle part of the centrifugal frame 3 through the boss 18, and then the motor 2 is driven to drive the centrifugal frame 3 and the screen 4 to rotate. At this time, the juice rotates with the centrifugal frame 3 and the juice is thrown out along the through holes of the screen 4, while the residue in the juice is retained in the centrifugal frame 3; S4, using the extraction barrel 1 to throw out the juice enclosure, and guide it to flow onto the bottom ring 12, and use the bottom ring 12 to drain it to the discharge pipe 14; S5. At this time, the last remaining residue in the juice falls into the collection bucket 15 by its own gravity, and finally the valve on the discharge pipe 14 is opened to discharge the finally obtained juice.

[0038] Remove the second nut 24 to remove the crushing barrel 5 from above the extraction barrel 1, and then remove the first nut 20 to remove the centrifugal frame 3. At this time, the crushing barrel 5, the screen 4 and the extraction barrel 1 can be cleaned separately.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
