Description

Technical Field

[0001] This utility model relates to the field of plant extraction technology, and in particular to a highly efficient device for extracting and processing active plant ingredients. Background Technology

[0002] Cold pressing, as the mainstream process for extracting essential oils from citrus fruits, relies on mechanical force to disrupt the structure of the oil glands in the peel. Traditional equipment suffers from significant uneven material distribution during operation: the peel accumulates in the center and sparsely surrounds it in a "hill-like" distribution, leading to an imbalance in pressure distribution when the pressing plate presses down. The overloaded central area easily causes excessive cell breakage and the introduction of impurities, while the under-pressurized edges contain a large number of unruptured glands, severely impacting the essential oil extraction rate and product purity. Existing solutions often employ manual leveling, which is inefficient, poses hygiene risks, and is cumbersome because the pressing chamber is typically in a relatively enclosed environment.

[0022] Please see Figures 1 to 4This application discloses a high-efficiency plant active ingredient extraction and processing device 1000, comprising a grinding chamber 1, a feeding rack 2, a grinding plate 3, a leveling plate 4, and a driving device 5. The grinding chamber 1 has a cavity, within which a fixing plate 11 is provided, dividing the cavity into an upper grinding chamber and a lower collecting chamber. The fixing plate 11 has multiple collecting holes. The feeding rack 2 is located on one side of the grinding chamber 1 and has an inclined channel communicating with the cavity. The grinding plate 3 is located at the top of the cavity. The leveling plate 4 is located on the lower side of the grinding chamber. The driving device 5 is located outside the grinding chamber 1 and is used to drive the leveling plate 4 from the lower side of the grinding chamber to the other side to level the fruit peel material piled on the fixing plate 11.

[0023] The compaction chamber 1 is divided into a compaction chamber and a collection chamber by a fixing plate 11. Collection holes on the fixing plate 11 allow the pressed liquid components to flow into the collection chamber. The inclined channel of the feed rack 2 facilitates material entry into the compaction chamber; the inclination angle can be adjusted according to the material characteristics, for example, between 30 and 60 degrees. The compaction plate 3 can be made of metal, and a raised section can be provided at the bottom to enhance the compaction effect. The leveling plate 4 can be made of metal or high-strength plastic, and its movement path can be set to a straight line or a curved trajectory. The drive device 5 can be an electric push rod, hydraulic cylinder, or pneumatic device, connected to the leveling plate 4 via a telescopic shaft 51. The moving speed of the leveling plate 4 is adjustable to adapt to the leveling requirements of different materials.

[0024] This technical solution effectively solves the problem of uneven distribution of fruit peel within the crushing chamber through the reciprocating motion of the leveling plate 4. The leveling plate 4 evenly spreads the accumulated material onto the fixed plate 11, ensuring uniform force on the material when the crushing plate 3 presses down, thus improving pressing efficiency. Compared to the uneven pressure distribution caused by the natural accumulation of material in existing technologies, this device ensures full pressing of material in all parts through mechanical leveling, thereby improving the essential oil extraction rate. This design avoids the manual intervention required in traditional processes, achieving automated operation.

[0025] Please see Figure 3 Furthermore, this application also proposes that one side of the collection cavity protrudes outward to form a placement position, in which the equalizing plate 4 is housed.

[0026] Specifically, the placement position is a recessed space formed by partially extending the sidewall of the collection chamber outward. This structure can be achieved by stamping or welding an additional cavity. In a preferred embodiment, the depth of the placement position is slightly greater than the thickness of the leveling plate 4, and its inner surface can be coated with an anti-rust coating. When not in operation, the leveling plate 4 is fully embedded in the placement position, flush with the sidewall of the collection chamber. Thus, this technical solution optimizes the collection chamber structure, ensuring the chamber's airtightness while providing dedicated storage space for the leveling plate 4. When the drive device 5 is not activated, the leveling plate 4 can be completely hidden in the placement position, avoiding interference with material entry and exit and the normal downward pressure of the compaction plate 3.

[0027] Please see Figure 4 Furthermore, this application also proposes that guide blocks 41 protrude from both sides of the uniform material plate 4, and guide rails 12 are recessed on the side wall of the compaction chamber. The guide rails 12 are arranged in a multi-level undulating shape, and the guide blocks 41 are located inside the guide rails 12. When the uniform material plate 4 moves, it moves along the undulating guide rails 12.

[0028] The guide block 41 and the guide rail 12 can be fitted together using a dovetail groove structure or a T-groove structure, with the height difference of the undulations of the guide rail 12 controlled within the range of 5-15mm. The undulation frequency of the guide rail 12 can be set to 3-5 peaks per 100mm length. As a preferred embodiment, the guide block 41 can be made of polytetrafluoroethylene (PTFE) to reduce frictional resistance. The undulation shape of the guide rail 12 can be arranged in a sinusoidal curve or a sawtooth pattern, with the sinusoidal curve shape being more conducive to the smooth transition of the uniform plate 4. The clearance tolerance between the guide block 41 and the guide rail 12 is controlled within the range of 0.1-0.3mm.

[0029] This technical solution utilizes multi-level, undulating guide tracks 12 to induce periodic vertical undulations in the material leveling plate 4 during its horizontal movement. As the material leveling plate 4 moves along the guide tracks 12, the guide blocks 41 drive it in a combined motion, achieving both horizontal material pushing and a kneading effect through vertical undulations. This motion effectively breaks up accumulated fruit peel materials, resulting in a more uniform distribution of the material on the fixed plate 11.

[0030] Please see Figure 3 and Figure 4 Furthermore, this application also proposes that the drive device 5 is provided with a telescopic shaft 51, which passes through the rolling box 1 and extends into the placement position. The placement position is also provided with a guide 52, the telescopic shaft 51 is connected to the guide 52, and the material leveling plate 4 is slidably connected to the guide 52.

[0031] The telescopic shaft 51 can be reciprocated linearly using a hydraulic cylinder or an electric actuator, and its stroke length must be adapted to the movement range of the material leveling plate 4. The guide member 52 is preferably a rectangular frame structure, with linear bearings or wear-resistant bushings installed on the inner wall of its through-hole to reduce frictional resistance when the guide strip 43 slides. The connection between the guide strip 43 and the plate body 42 can be achieved, but is not limited to, bolt fixing, welding, or integral molding. Vertical sliding connection can be achieved by providing grooves on the surface of the guide strip 43 that engage with protrusions in the guide member 52, or by using a dovetail groove guide rail structure.

[0032] This technical solution uses a telescopic shaft 51 to drive the guide component 52 to move horizontally, thereby causing the material leveling plate 4 to complete the material leveling operation. The sliding connection structure between the guide component 52 and the material leveling plate 4 allows the material leveling plate 4 to adapt to height changes as it moves along the undulating guide track 12, preventing the mechanism from jamming. Compared with existing technologies, this design achieves precise control of the material leveling plate 4's movement trajectory, ensuring uniform material layer thickness and a more reasonable pressure distribution in subsequent compaction processes. Specifically, when the guide block 41 moves along the multi-level undulating guide track 12, the guide strip 43 slides up and down within the through hole to compensate for height differences, maintaining stable contact pressure between the material leveling teeth 44 and the material surface, thus improving the leveling effect.

[0033] Please see Figure 4 Furthermore, this application also proposes that the guide member 52 is provided through at both ends, the material leveling plate 4 includes a plate body 42 and a guide strip 43, the guide strip 43 passes through the through hole of the guide member 52, the two ends of the guide strip 43 are connected to the plate body 42, and the guide strip 43 slides up and down in the through hole of the guide member 52.

[0034] The guide member 52 adopts a through-hole design, allowing the guide strip 43 to move vertically within the hole. The guide strip 43 can be a cylindrical metal rod or a rectangular cross-section metal strip, with its diameter or width slightly smaller than the inner diameter of the through hole, forming a clearance fit. The plate body 42 and the guide strip 43 are rigidly connected by welding or bolting. As a preferred embodiment, the surface of the guide strip 43 can be coated with polytetrafluoroethylene to reduce the coefficient of sliding friction. A copper sleeve can be embedded in the inner wall of the through hole of the guide member 52 as a wear-resistant bushing to further reduce friction loss. The clearance between the guide strip 43 and the through hole is controlled within the range of 0.1-0.3mm, ensuring smooth sliding while avoiding excessive wobble.

[0035] This technical solution achieves the adaptive adjustment function of the uniform material plate 4 in the vertical direction through the sliding fit structure between the guide strip 43 and the through hole. When the uniform material plate 4 moves in the compaction chamber, the guide strip 43 can slide up and down along the through hole, allowing the uniform material plate 4 to automatically adjust its height position according to the material accumulation thickness. Specifically, the sliding stroke of the guide strip 43 in the through hole is designed to be 20-30mm, which can effectively compensate for the height difference caused by changes in material thickness. This solves the problem in the prior art where the fixed height of the uniform material plate 4 cannot adapt to uneven material distribution, ensuring that the uniform material teeth 44 always maintain optimal contact pressure with the material surface. Compared with the traditional rigid connection method, this structure significantly improves the uniformity of material leveling, creating more uniform material distribution conditions for subsequent compaction processes.

[0036] Please see Figure 3 and Figure 4 Furthermore, this application also proposes that the bottom of the uniform plate 4 is provided with uniform teeth 44.

[0037] The material leveling teeth 44 can take various forms: the tooth shape can be designed as triangular, trapezoidal, or wavy, with a tooth height ranging from 3-10 mm and a tooth spacing of 5-15 mm; the material can be stainless steel or hard engineering plastic; the installation method can be welding, bolt fixing, or integral casting. As a preferred embodiment, the material leveling teeth 44 have an equidistantly arranged conical structure with a tooth tip angle of 45-60 degrees. This structure can effectively break up material agglomerates during movement.

[0038] Specifically, by setting uniform distribution teeth 44 at the bottom of the uniform distribution plate 4, when the driving device 5 drives the uniform distribution plate 4 to reciprocate, the uniform distribution teeth 44 can penetrate the material layer for crushing and turning. The undulating guide rail 12 causes the uniform distribution plate 4 to move vertically, and in conjunction with the toothed structure of the uniform distribution teeth 44, it can generate multi-directional forces on the fruit peel material accumulated on the fixed plate 11. This achieves uniform leveling and pre-crushing of the material layer, solving the problem of concentrated pressure in the middle caused by uneven material distribution in traditional pressing processes.

[0039] Please see Figure 2 Furthermore, this application also proposes that a crushing roller 6 is provided at the top of the inclined channel, the crushing roller 6 being used to pre-crush the citrus peel material.

[0040] The specific implementation of the crushing roller 6 includes, but is not limited to: using a metal roller with a textured surface to generate shearing force on the fruit peel through rotational motion; the roller surface can be equipped with spirally arranged crushing teeth to enhance the crushing effect when the material passes through; the roller speed is controlled within the range of 20-50 rpm to ensure crushing efficiency while avoiding excessive compression that could lead to premature evaporation of the essential oil. As a preferred embodiment, the angle between the crushing roller 6 and the inclined channel is set to 15-30 degrees, allowing the material to pass through the crushing area naturally under the action of gravity.

[0041] This technical solution pre-crushes the material before it enters the crushing chamber by adding a crushing roller 6. Specifically, the whole fruit peel is crushed by the crushing roller 6 into uniformly sized fragments, resulting in a more even distribution of material during the subsequent crushing process. This solves the problem of uneven crushing pressure distribution caused by differences in material size in traditional processes. The pre-crushed material is also more easily leveled by the leveling plate 4 in the crushing chamber, thus ensuring a more uniform pressure distribution when the crushing plate 3 presses down, effectively improving the efficiency of essential oil extraction.

[0042] Please see Figure 2 Furthermore, this application also proposes that the number of crushing rollers 6 is two, and multiple extrusion rings are provided on the surface of the crushing rollers 6, with the multiple extrusion rings on the two crushing rollers 6 being arranged alternately.

[0043] Specifically, the extrusion ring is an annular protrusion structure arranged along the axial direction of the crushing roller 6, and its cross-sectional shape can be semi-circular, trapezoidal, or triangular. In a preferred embodiment, the extrusion ring is made of hard alloy material, and its surface is polished to reduce material adhesion. The staggered arrangement means that the extrusion rings of the two crushing rollers 6 are arranged at intervals in their axial projection, forming a continuously changing extrusion gap when the two rollers rotate in opposite directions. For example, the spacing between the extrusion rings can be set to 5-8 mm, the height to 3-5 mm, and the distance between the two rollers can be adjusted within a range of 0.5-2 mm. Furthermore, the extrusion ring can be designed as a detachable structure, fixed to the roller base with bolts, facilitating the replacement of extrusion rings of different sizes according to material characteristics.

[0044] This technical solution achieves gradient crushing of fruit peel materials through a double-roller staggered extrusion structure. When the fruit peel enters between the two crushing rollers 6 through the feed rack 2, it is first subjected to initial crushing by the high-level extrusion ring. As the rollers rotate, the material enters the smaller gap formed by adjacent extrusion rings for secondary crushing. The staggered layout allows the material to withstand multi-directional shear forces, avoiding the fiber entanglement problem caused by traditional single-roller crushing.

[0045] The bottom of the rolling mill plate 3 is provided with multiple protrusions. Specifically, the protrusions can be conical, hemispherical, or prismatic in shape, with a height ranging from 3 to 8 mm, and the spacing between adjacent protrusions controlled at 5 to 15 mm. As a preferred embodiment, the protrusions are made of hard alloy material and are fixed to the bottom surface of the rolling mill plate 3 by threaded connection or welding. Furthermore, the protrusions can be distributed in an array or radially, with the radial distribution facilitating the diffusion of material to the outer periphery.

[0046] Therefore, when the pressing plate 3 is pressed down, the protrusions can effectively penetrate the surface of the peel, causing the oil glands to rupture more fully. Compared with the flat pressing plate 3, the local pressure generated by the protrusions is increased by 2-3 times, significantly improving the essential oil release rate under the same pressure conditions. At the same time, the grooves formed by the protrusions help the crushed material to spread evenly to the outer periphery, avoiding excessive accumulation of material in the middle. Specific tests show that the pressing plate 3 with this structure can increase the essential oil extraction rate of citrus peel by 18%-22% without increasing the load on the drive device 5.

[0047] Please see Figure 2 Furthermore, this application also proposes that a collection box 7 is provided inside the collection cavity, and the collection box 7 is pushed and pulled inside the collection cavity.

[0048] Specifically, the collection box 7 adopts a drawer-type structure design, and is connected to the side wall of the collection chamber by a sliding rail mechanism for push-pull operation. As a preferred embodiment, the sliding rail mechanism can use ball bearing rails or linear bearing rails to ensure smooth movement of the collection box 7 even when carrying materials. A handle or groove structure can be provided at the front end of the collection box 7 for easy operation, and a 1-3mm gap is maintained between the bottom of the box and the fixing plate 11 to prevent friction. Furthermore, a limiting protrusion can be provided on the side wall of the collection box 7, which cooperates with the limiting groove on the side wall of the collection chamber to ensure accurate positioning of the end point of the push-pull stroke. The collection box 7 is preferably made of food-grade stainless steel with a thickness of 1.2-2mm, ensuring both structural strength and ease of cleaning and maintenance.

[0049] This technical solution effectively solves the problems of difficult cleaning and residual material accumulation in traditional fixed collection chambers through the design of a pull-out collection box 7. When the crushed material falls through the collection hole, it can directly enter the movable collection box 7, allowing operators to remove the material and clean the chamber without opening the entire device.

[0050] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
