Description
Technical Field
[0001] This utility model relates to the technical field of phenolic substance extraction devices, specifically to a device for extracting phenolic substances from orchid plants that are both medicinal and edible. Background Technology
[0002] Orchids, as important medicinal and edible resources, have a long history of application in traditional Chinese medicine and diet. Gastrodia elata and Dendrobium officinale are typical examples. Studies have shown that the bioactivity of these orchids is closely related to their rich content of phenolic substances. Gastrodia elata is rich in phenolic components such as gastrodin and barisonin. Modern pharmacological studies have confirmed that gastrodin has sedative and neuroprotective effects, while barisonin exhibits good antioxidant activity. Dendrobium officinale contains phenolic substances such as dendrobin, which show significant activity in enhancing immunity, anti-inflammation, and anti-aging. Due to their unique chemical structure and physiological functions, these phenolic substances have become a key focus of research and development in medicine and health food.
[0003] The prior art discloses a phenolic compound extraction device (publication number: CN214075291U), including a shell, a pull plate, a stirring and pulverizing mechanism, a filtering mechanism, a bottom plate, a separation mechanism, an observation window, a collection port, and a feed hopper; the top of the shell has a feed port, and the feed hopper is located at the feed port; the pull plate is horizontally and movably disposed in the shell, and the bottom plate is inclinedly disposed in the shell and located below the pull plate; the stirring and pulverizing mechanism is rotatably disposed in the shell and located above the pull plate; the filtering mechanism is inclinedly disposed between the pull plate and the bottom plate; the observation window is located in the middle of one side of the shell; a strip-shaped drain hole is vertically disposed on one side of the shell between the filtering mechanism and the bottom plate, and the separation mechanism is at least partially and movably located inside the strip-shaped drain hole; the collection port is located at the bottom end of the shell near the bottom plate.
[0004] Existing technologies improve filtration efficiency and facilitate the collection of sediments and discharge of slag by tilting the filtration mechanism. However, the filtered material still contains a large amount of phenolic substances. Directly discharging the filtered material results in significant waste and increases the cost of factory production. To address these issues, we propose a device for extracting phenolic substances from orchid plants that are both medicinal and edible. Utility Model Content
[0005] The present invention aims to provide a device for extracting phenolic substances from orchid plants that are both medicinal and edible, in order to solve the problem that directly discharging the filtered material results in a large amount of waste and increases the production cost of the factory.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an extraction device for phenolic substances from orchid plants that are both medicinal and edible, comprising an extraction box, a filter discharge port on the side wall of the extraction box, a pressing box on the outer wall of the extraction box near the filter discharge port, a pressing assembly inside the pressing box, the pressing assembly including a driving component, a pressing plate, a mounting plate and a discharge plate, the mounting plate being disposed on the inner wall of the pressing box, the driving component being disposed at the end of the pressing box away from the extraction box, and the output end of the driving component extending through the pressing box into the pressing box, the pressing plate being disposed at the output end of the driving component, and the pressing plate being able to abut against the outer wall of the extraction box, the discharge plate being hinged to the end of the mounting plate near the extraction box, a trigger plate being disposed at the upper end of the discharge plate, the pressing plate being able to contact the trigger plate, a reset component being disposed between the discharge plate and the mounting plate, and a cover component being disposed between the pressing assembly and the filter discharge port.
[0007] The beneficial effects of this solution are as follows: After filtration, the material falls through the filter discharge port onto the upper part of the mounting plate and the discharge plate. At this time, the driving component pushes the extrusion plate to move, causing the material on the mounting plate to be pushed towards the outer wall of the extraction box. As the material accumulates and is squeezed against each other, the residual phenolic liquid in the material flows out, thereby improving the extraction rate of phenolic substances in the raw material and reducing the cost of factory production. As the extrusion plate continues to move, it abuts against the trigger plate and pushes the trigger plate to rotate, causing the discharge plate to rotate around the hinge point. This creates a gap between the mounting plate and the extraction box. When the extrusion plate contracts under the action of the driving component after extrusion, the pressed material loses the extrusion pressure and is discharged from the gap under the action of gravity. As the extrusion plate continues to retract until it separates from the trigger plate, the trigger plate is reset under the action of the reset component, eliminating the gap between the mounting plate and the extraction box. This allows the next batch of material to be pressed to accumulate on the upper part of the mounting plate and the discharge plate, facilitating the pressing assembly to press the next batch of material.
[0008] Preferably, as an improvement, the covering assembly includes a covering plate and two lifting plates. The inner wall of the pressing box is symmetrically provided with sliding grooves. The covering plate is slidably installed between the two sliding grooves. The covering plate is provided with a through hole that matches the filter discharge port. The two lifting plates are symmetrically arranged at the end of the covering plate near the extrusion plate, and both lifting plates abut against the extrusion plate. The end of the lifting plate near the mounting plate is provided with a first plane and a second plane. The first plane and the second plane are connected by an inclined plane. When the extrusion plate abuts against the first plane, the filter discharge port is connected to the through hole. When the extrusion plate abuts against the second plane, the covering plate covers the filter discharge port.
[0009] The beneficial effects are as follows: when the extrusion plate abuts against the first plane, the through hole of the cover plate is aligned with and connected to the filter discharge port, ensuring that the material in the extraction box can smoothly enter the pressing box; when the extrusion plate moves forward to perform the pressing operation, the extrusion plate transitions to the second plane through the inclined surface, so that the cover plate rises synchronously with the lifting plate, thereby automatically covering the filter discharge port, preventing the material from continuously being discharged from the filter discharge port when the pressing component is pressing, which would cause the material to accumulate between the extrusion plate and the driving component, making the pressing component unable to operate normally.
[0010] Preferably, as an improvement, the reset element is a torsion spring, and the driving element is a telescopic hydraulic cylinder.
[0011] Preferably, as an improvement, the end of the discharge plate near the lifting plate is symmetrically provided with a limiting groove, and the end of the mounting plate near the discharge plate is symmetrically provided with a limiting plate, which can abut against the limiting groove.
[0012] The beneficial effects are: through the cooperation of the limiting plate and the limiting groove, the discharge plate and the mounting plate are located on the same horizontal plane, ensuring the smooth operation of the extrusion plate.
[0013] Preferably, as an improvement, the extraction box is provided with a diversion plate at one end near the pressing box, and a plurality of diversion holes are evenly opened at the end of the diversion plate near the mounting plate. The diversion holes are connected to the inside of the extraction box, and a diversion groove is opened at the end of the diversion plate near the mounting plate to connect the plurality of diversion holes.
[0014] The beneficial effects are as follows: When the pressing component presses the material, the squeezed phenolic liquid drips onto the upper part of the guide plate and flows along the surface of the guide plate until the phenolic liquid flows into the extraction box through the guide hole. This prevents the phenolic liquid from remaining in the pressing box or being discharged with the pressed residue. The guide groove is used to connect all the guide holes and block the continued flow of the phenolic liquid, so that all the phenolic liquid attached to the guide plate flows into the guide groove and then into the extraction box through the guide hole.
[0015] Preferably, as an improvement, the lower end of the through hole is provided with an inclined surface.
[0016] The beneficial effect is that by setting an inclined surface at the lower end of the through hole, the material is prevented from staying at the upper end of the through hole and causing blockage of the filter discharge port.
[0017] Preferably, as an improvement, the inner wall of the extraction box is provided with an upper filter plate and a lower filter plate that are parallel to each other, and the aperture of the upper filter plate is larger than that of the lower filter plate. The filter discharge port is respectively opened on the lower side wall of the extraction box near the upper filter plate and the lower filter plate.
[0018] Preferably, as an improvement, the inner wall of the extraction box is provided with several heating elements, which are heating tubes.
[0019] The beneficial effects are as follows: by heating the phenolic liquid in the extraction chamber, the solubility of phenolic substances in the solvent can be increased, and the diffusion of phenolic components in plant cells into the solvent can be accelerated, thereby shortening the extraction time and increasing the amount of phenolic substances extracted per unit time.
[0020] Preferably, as an improvement, the end of the pressing box away from the extraction box is provided with a waste outlet, and the waste outlet is hinged to a cover. Attached Figure Description

[0027] Example
[0028] The basic implementation examples are as follows: Figures 1-4 As shown, Figure 1 The apparatus shown is for extracting phenolic substances from orchid plants that are both medicinal and edible, including an extraction chamber 1, such as... Figure 2The extraction box 1 shown has an upper filter plate 2 and a lower filter plate 3 fixedly installed on its inner wall at an incline. The upper filter plate 2 has a larger aperture than the lower filter plate 3. A filter discharge port 4 is provided at the right end of the extraction box 1, which abuts against the lower ends of the upper filter plate 2 and the lower filter plate 3. The filter discharge port 4 is connected to the inside of the pressing box 5. A pressing box 5 is provided on the outer wall of the right end of the extraction box 1. A pressing assembly is provided inside the pressing box 5. The pressing assembly includes a driving component 7, a pressing plate 8, a mounting plate 6, and a discharge plate 29. The mounting plate 6 is fixedly installed on the inner wall of the pressing box 5, and its upper end is covered with a stainless steel layer. A support plate is fixedly installed on the outer wall of the right end of the pressing box 5. The driving component 7 is fixedly installed on the upper end of the support plate. The output end of drive component 7 extends through the pressing box 5 and into the pressing box 5. Drive component 7 is set as a telescopic hydraulic cylinder. Extrusion plate 8 is fixedly installed at the output end of drive component 7, and the lower end of extrusion plate 8 abuts against the upper end of mounting plate 6. Force plate 9 is fixedly installed on the outer wall of the right end of extraction box 1. The right end of force plate 9 and the left end of extrusion plate 8 are both covered with stainless steel. Drive component 7 can push extrusion plate 8 to contact force plate 9. Rotation groove 10 is opened on the left end of mounting plate 6. Rotating rod is fixedly installed on the inner wall of rotation groove 10. Discharge plate 29 is rotatably installed on the outer wall of rotating rod. Trigger plate 11 is fixedly installed on the upper end of discharge plate 29. Trigger plate 11 and rotating rod are located on the same plane. The lower end of extrusion plate 8 can contact trigger plate 11. Figure 3 and Figure 4 The discharge plate 29 shown is fixedly equipped with reset pieces 12 at both its front and rear ends and the inner wall of the rotating groove 10. The reset pieces 12 are sleeved on the outer wall of the rotating rod and are designed as torsion springs. Limiting grooves 13 are symmetrically formed on both the front and rear sides of the right end of the discharge plate 29. Limiting plates 14 are symmetrically fixedly installed on the left end of the mounting plate 6, and the limiting plates 14 can abut against the inner wall of the limiting grooves 13. Through the cooperation of the limiting plates 14 and the limiting grooves 13, the discharge plate 29 and the mounting plate 6 are positioned on the same horizontal plane, ensuring the smooth operation of the extrusion plate 8. Figure 2The extraction box 1 shown is fixedly equipped with a flow guide plate 15 on its right end. The flow guide plate 15 is S-shaped and guides the phenolic liquid to flow downwards. Several flow guide holes 16 are vertically opened on the outer wall of the flow guide plate 15, and each flow guide hole 16 is connected to the inside of the extraction box 1. A flow guide groove 17 is opened on the right end of the flow guide plate 15, which connects the several flow guide holes 16. A filter screen is fixedly installed on the outer wall of the flow guide groove 17, and the filter screen smoothly transitions to the outer wall of the flow guide plate 15. The filter screen is used to prevent the residue after pressing from remaining in the flow guide groove 17. When the pressing component presses the material, the extruded phenolic liquid... The phenolic liquid drips onto the upper end of the guide plate 15 and flows along the surface of the guide plate 15 until it flows into the extraction box 1 through the guide hole 16. This prevents the phenolic liquid from remaining in the pressing box 5 or being discharged with the pressed residue. The guide trough 17 is used to connect all the guide holes 16 and block the continued flow of the phenolic liquid, so that all the phenolic liquid attached to the guide plate 15 flows into the guide trough 17 and then into the extraction box 1 through the guide hole 16. A cover assembly is provided between the pressing assembly and the filter discharge port 4.
[0029] The masking assembly includes a masking plate 19 and two lifting plates 21, such as Figure 3 The pressing box 5 shown has symmetrically arranged sliding grooves 18 on its front and rear inner walls. The cover plate 19 is slidably installed between the two sliding grooves 18. Figure 2 The cover plate 19 shown has through holes 20 that match the filter discharge port 4, and the lower end of the through hole 20 is set as an inclined surface to prevent material from staying on the upper end of the through hole 20 and causing blockage of the filter discharge port 4. Two lifting plates 21 are symmetrically fixedly installed on the front and rear sides of the right end of the cover plate 19. A connecting plate is fixedly installed on the right end of the two lifting plates 21, so that the cover plate 19, the lifting plates 21 and the connecting plate form a frame structure, thereby improving the stability of the lifting of the cover plate 19. The lower ends of the two lifting plates 21 abut against the upper end of the extrusion plate 8. The lower end of each lifting plate 21 is provided with a first plane 22 and a second plane 23, and the first plane 22 and the second plane 23 are connected by an inclined surface. When the extrusion plate 8 abuts against the first plane 22, the filter discharge port 4 is connected to the through hole 20. When the extrusion plate 8 abuts against the second plane 23, the cover plate 19 covers the filter discharge port 4.
[0030] like Figure 2The pressing chamber 5 shown has a waste outlet on its lower right side, with a hinged cover 24 installed inside. The waste outlet is used to discharge the material that has been squeezed in the pressing chamber 5. Several heating elements 25 are fixedly installed on the inner wall of the extraction chamber 1. The heating elements 25 are heating tubes. By heating the phenolic liquid in the extraction chamber 1, the solubility of phenolic substances in the solvent can be increased, and the diffusion of phenolic components in plant cells into the solvent can be accelerated, thereby shortening the extraction time and increasing the amount of phenolic substances extracted per unit time. A feed funnel 27 is connected to the upper end of the extraction chamber 1. The feed funnel 27 is used to transport the crushed orchid plants into the extraction chamber 1. A discharge port 28 is connected to the left end of the extraction chamber 1. Figure 1 The extraction box 1 and the pressing box 5 shown are both equipped with a viewing window 26 at their front ends, through which the working conditions inside the extraction box 1 and the pressing box 5 can be seen intuitively.
[0031] The specific implementation process is as follows:
[0032] In its initial state, the extrusion plate 8 abuts against the first plane 22 at the lower end of the lifting plate 21. At this time, the through hole 20 of the cover plate 19 is aligned with and connected to the filter discharge port 4, allowing the material filtered by the upper filter plate 2 and the lower filter plate 3 to fall through the filter discharge port 4 onto the mounting plate 6 and the upper end of the discharge plate 29. When the operator observes through the viewing window 26 that the material on the upper end of the mounting plate 6 has accumulated to a certain extent, the operator activates the drive component 7 to push the extrusion plate 8 forward to perform the pressing operation. When the extrusion plate 8 transitions through the inclined plane to the lifting plate 21... When the lower plate 21 reaches the second plane 23 at its lower end, the cover plate 19 rises synchronously with the lifting plate 21, thereby automatically covering the filter discharge port 4. This prevents material from continuously being discharged from the filter discharge port 4 during the pressing assembly, which would cause material to accumulate between the extrusion plate 8 and the drive component 7, preventing the pressing assembly from operating normally. As the extrusion plate 8 continues to move, the material on the mounting plate 6 is pushed by the extrusion plate 8 to the right end of the force plate 9. As the material accumulates in large quantities and is squeezed against each other, the residual phenolic liquid in the material flows out. The phenolic liquid drips onto the upper end of the guide plate 15 and flows along its surface into the guide trough 17. It then flows through the guide holes 16 into the extraction box 1, preventing the phenolic liquid from remaining in the pressing box 5 or being discharged with the pressed residue. This improves the extraction rate of phenolic substances from the raw material and reduces factory production costs. When the extrusion plate 8 abuts against the trigger plate 11 and pushes the trigger plate 11 to rotate, the trigger plate 11 drives the discharge plate 29 to rotate around the rotating rod, thereby causing the mounting plate 6 to contact the force-bearing plate. A gap appears between the plates 9. When the extrusion plate 8 shrinks under the action of the drive component 7 after the extrusion is completed, the material after extrusion loses the extrusion pressure and is discharged from the gap under the action of gravity. As the extrusion plate 8 continues to retract until it separates from the trigger plate 11, the trigger plate 11 is reset under the action of the reset component 12, so that the gap between the mounting plate 6 and the force plate 9 disappears, and the next batch of material to be extruded accumulates on the mounting plate 6 and the discharge plate 29, so that the extrusion assembly can extrude the next batch of material.
