Description

Technical Field

[0001] The present application relates to the field of plant extraction, and in particular to an extraction device for osmanthus extract. Background Art

[0002] Osmanthus fragrans is a precious natural spice. Its active ingredient, osmanthus essential oil, is widely used in various food and cosmetic products as a high-end spice. It has the effects of calming, antibacterial, air purification, dispelling cold and rheumatism, phlegm and cough, promoting qi and relieving pain, dispersing blood and stopping diarrhea, and removing bad breath. It is also an excellent mood booster and air freshener. The commonly used method for extracting osmanthus volatile oil is steam distillation (SD). The SD method is simple to operate, low in cost, and has a large extraction volume. However, some heat-sensitive substances or unstable substances are easily hydrolyzed and destroyed during the high temperature process, and the obtained essential oil has poor aroma and low purity.

[0003] For example, patent number CN201620587009.1, an extractor for extracting osmanthus, includes a feeding device, characterized in that a drying device is provided at the bottom of the feeding device, the bottom of the drying device is connected to a crushing device through a pipeline, one side of the crushing device is connected to an extraction box through a pipeline, a controller is provided at the top of the extraction box, a liquid crystal display is inlaid on the outer wall of the controller, a first control button and a second control button are provided below the liquid crystal display, a degreasing filter is provided in the inner cavity of the extraction box, a heating device is provided at the bottom of the inner cavity of the extraction box, one side of the extraction box is connected to an exhaust pump through a pipeline, and one side of the exhaust pump is connected to a condenser through a pipeline. The above device has the following shortcomings in actual use:

[0004] The device uses a drying device to bake osmanthus to remove the essential oil. After the essential oil is removed, it is distilled by heating and condensing to achieve the extraction effect. However, the temperature difference caused by the distillation method can easily degrade the molecular structure inside the essential oil, reduce the purity of the essential oil, and thus affect the quality of the extract.

[0029] 2. The baffle fixed on the surface of the filter plate is used to intercept the osmanthus residue to form a filtering effect. At the same time, the extract flows into the side groove along the inclined surface and finally enters the bottom of the storage shell, thereby slowing down the flow rate of the extract. The filter net set at the bottom of the faucet is used to perform secondary filtration on the residue in the extract to avoid residual impurities affecting the purity of the extract.

[0040] The following is combined with Figure 1 —5 Further details of this application are provided.

[0041] The embodiment of the present application discloses an extraction device for osmanthus extract.

[0042] Example 1

[0043] Reference Figure 1 An extraction device for osmanthus extract comprises a main shell 1, a feeding shell 3 is welded and fixed to the upper end surface of the main shell 1, the feeding shell 3 is funnel-shaped and communicated with the main shell 1, and is used to feed osmanthus raw materials;

[0044] Reference Figure 2 , 3 The first crushing mechanism 4 includes a first grinding wheel 42 rotatably connected to both sides of the inner wall of the main shell 1, and a rotating shaft is embedded and fixed on the end surface of the first grinding wheel 42 close to the main shell 1, and the end surface of the rotating shaft away from the first grinding wheel 42 is rotatably plugged into the main shell 1, and a servo motor 41 is fixedly provided at a position opposite to the first grinding wheel 42 on one side of the outer surface of the main shell 1, and the output shaft of the servo motor 41 movably passes through the main shell 1 and is fixedly connected to the rotating shaft of the first grinding wheel 42.

[0045] Through the above arrangement, the output shaft of the servo motor 41 is fixedly connected to the rotating shaft on one side of the first grinding wheel 42 , so that when the servo motor 41 rotates, the first grinding wheel 42 is driven to rotate synchronously, thereby providing power for the first grinding mechanism 4 .

[0046] Reference Figure 3 A plurality of first grinding teeth 43 are fixedly arranged around the surface of the first grinding wheel 42. The plurality of first grinding teeth 43 are all in a rhombus shape and have an angle of 60° with the roller surface of the first grinding wheel 42. A liquid outlet groove 44 is provided on the surface of the first grinding tooth 43 facing the other first grinding tooth 43. The liquid outlet groove 44 passes through the bottom of the first grinding tooth 43 and is connected with the roller surface of the first grinding wheel 42. A circular cavity 45 is provided inside the first grinding wheel 42. The opening of the cavity 45 is embedded and fixed with the outer ring of the sealing bearing. The inner surface of the cavity 45 is provided with a There are longitudinal grooves 46, the number of which is the same as the number of liquid outlet grooves 44, and the longitudinal grooves 46 are aligned with the center of the bottom of the liquid outlet groove 44; a conduit 47 is inserted and fixedly connected to one side of the main shell 1 at a position relative to the cavity 45, one end of the conduit 47 is inserted and fixed to the inner ring of the sealing bearing (the outer diameter of the conduit 47 is consistent with the inner diameter of the inner ring of the sealing bearing to achieve an interference fit), and the end of the conduit 47 close to the cavity 45 passes through the side wall of the main shell 1 and is connected to the cavity 45. This arrangement enables the conduit 47 to act as a rotating shaft.

[0047] Through the above arrangement, the liquid outlet trough 44 is connected with the longitudinal groove 46, and then the liquid outlet trough 44 is connected with the inside of the cavity 45. When the first grinding wheel 42 rotates, it will drive the outer ring of the sealed bearing to rotate on the ball. The rotation of the ball will not affect the inner ring of the sealed bearing. Therefore, the conduit 47 will not rotate and the extractant can be transported in real time, so that the extractant accumulates inside the cavity 45 and generates pressure, flows out of the liquid outlet trough 44 through the longitudinal groove 46, and finally contacts with the osmanthus raw material for mixing and configuration.

[0048] It should be noted that the other end of the conduit 47 away from the cavity 45 should be provided with a water injection device such as a control valve and a liquid pump, but since it is not a major technology, it will not be described in detail.

[0049] Reference Figure 2 The second grinding mechanism 5 includes a second grinding wheel 51 rotatably connected to both sides of the inner wall of the main shell 1, and a plurality of second grinding teeth 52 (the number is the same as the first grinding teeth 43) are integrally provided on the surface of the second grinding wheel 51; it should be noted that there is a certain distance between the second grinding wheel 51 and the roller surface of the first grinding wheel 42, so that the second grinding teeth 52 are meshed with the first grinding teeth 43.

[0050] Through the above arrangement, the second grinding teeth 52 are in a meshing state with the first grinding teeth 43. When the first grinding wheel 42 rotates, the first grinding teeth 43 apply thrust to the second grinding teeth 52, causing the second grinding wheel 51 to rotate in the opposite direction. While the second grinding wheel 51 rotates, it interacts with the first grinding wheel 42 to form an interaction force, so that the first grinding teeth 43 and the second grinding teeth 52 are clamped during the rotation process, thereby crushing the osmanthus raw material.

[0051] Reference Figure 2 , 4A storage shell 2 is welded and fixed to the lower end surface of the main shell 1, and a mounting groove 12 is provided on one side of the storage shell 2. The mounting groove 12 penetrates the side wall of the storage shell 2 and is connected to the hollow part in the middle of the storage shell 2. At the same time, the inner wall of the storage shell 2 located on both sides of the mounting groove 12 is provided with sliding grooves 11; two guide plates 10 are fixedly provided on the inner wall of the storage shell 2 relative to the other side of the mounting groove 12, and the surfaces of the two guide plates 10 are inclined at 15°, and a certain space is reserved between the ends of the guide plates 10 and the inner wall of the storage shell 2, and a filtering mechanism 6 is movably inserted between the two guide plates 10 on the inner wall of the storage shell 2, and the filtering mechanism 6 includes two sliding grooves 11 slidably arranged, and the groove surface of the sliding groove 11 is flush with the side wall of the main shell 1, and a slider 64 in the groove, and a filter plate 61 is fixedly provided on the opposite side of the two sliders 64, and a rubber film 65 is glued around the outer surface of the filter plate 61 located in the mounting groove 12, and the width of the rubber film 65 is consistent with the groove width of the mounting groove 12.

[0052] Through the above arrangement, the filter plate 61 is pushed to make the slider 64 move along the channel of the slide groove 11, and the filter plate 61 is movably inserted from the mounting groove 12 into the storage shell 2, so that the filter plate 61 is cleaned regularly to prevent excessive residues. When the filter plate 61 is fully inserted into the storage shell 2, the rubber membrane 65 fixed on the outer surface of the filter plate 61 fills the gap between the filter plate 61 and the mounting groove 12, thereby sealing the interior of the storage shell 2. At the same time, when the extract flows into the inclined surfaces of the two guide plates 10, the flow direction is changed by the inclination angle to slow down the flow rate.

[0053] Reference Figure 4 , 5 The upper end surface of the filter plate 61 is set as an inclined step surface 62, the inclined step surface 62 has the middle part as the top, and both sides are inclined downward by 2 to 3 degrees, and side grooves 66 are opened downward at the inclined ends of both sides; a plurality of baffles 63 are fixed on the surface of the inclined step surface 62, and the baffles 63 are triangular and the angle between them and the inclined step surface 62 is set to 60 degrees.

[0054] Through the above arrangement, the surface of the filter plate 61 is set as an inclined surface 62, and a baffle 63 is fixedly provided on the inclined surface 62 to block the inflowing liquid to a certain extent and slow down the flow rate of the liquid. At the same time, there is an angle between the baffle 63 and the inclined surface 62, so that when the liquid flows through, the osmanthus residue in the liquid is intercepted. The side grooves 66 opened on both sides of the filter plate 61 are used to divert the liquid to help slow down the flow rate of the liquid.

[0055] Reference Figure 2 , 4A drainage hole 7 is provided on one side of the inner wall of the storage shell 2, and the drainage hole 7 passes through the storage shell 2 and is connected to the outside. At the same time, a faucet 8 is fixedly provided on the outer surface of the storage shell 2 at the position of the connecting hole for discharging liquid (the faucet 8 is a conventional device and is not described in detail), and a filter screen 9 is threadedly connected to the bottom surface of the faucet 8.

[0056] Through the above arrangement, when the faucet 8 is turned on, the extract in the storage shell 2 enters the faucet 8 through the drainage hole 7 and is then discharged from the outside of the device. During the extraction liquid discharge process, the filter screen 9 performs secondary filtration on the osmanthus residue remaining in the liquid. At the same time, the filter screen 9 can be rotated to be disassembled so that the filter screen can be cleaned or replaced regularly.

[0057] Reference Figure 2 An observation window 13 is provided on the outer surface of the storage shell 2 at a relative position between the guide plate 10 and the filter plate 61 . The observation window 13 is made of glass material, which is convenient for observing the extraction degree of the extract inside the storage shell 2 .

[0058] Among them, the device also includes sealed bearings, microcomputers, compilers, servo motors 41 and other structures, which are all existing technologies, and their structural principles will not be repeated. At the same time, the sealed bearings include outer rings, inner rings, sealing rings and balls, which are existing and mature technologies, and the installation method will not be described in detail.

[0059] The implementation principle of the extraction device of an osmanthus extract in the embodiment of the present application is as follows:

[0060] When using this device, the microcomputer sends a signal to enable the compiler to control the servo motor 41 to start. The servo motor 41 rotates and drives the first grinding wheel 42 to rotate synchronously. The first grinding tooth 43 applies a downward thrust to the second grinding tooth 52 through the rotation of the first grinding wheel 42. The second grinding tooth 52 is subjected to the thrust and moves to a certain extent. In this process, the second grinding wheel 51 rotates in the opposite direction with the first grinding wheel 42.

[0061] The cleaned osmanthus raw material is poured into the feeding shell 3, and the osmanthus raw material falls between the first grinding wheel 42 and the second grinding wheel 51 along the middle of the feeding shell 3. The first grinding wheel 42 and the second grinding wheel 51 rotate in opposite directions to form a force, so that the osmanthus raw material between the two grinding wheels is squeezed and crushed. While the osmanthus raw material is being crushed, the microcomputer sends a signal to control the water injection device to inject the extraction solvent. The extraction solvent is injected into the cavity 45 through the conduit 47, and then flows out from the liquid outlet trough 44 to contact with the crushed osmanthus raw material to form a mixture. In addition, the rotation of the first grinding wheel 42 and the second grinding wheel 51 also provides a certain stirring force for the mixing of the osmanthus raw material and the solvent.

[0062] After the stirring is completed, the extract flows into the storage housing 2, and gradually fills up with the injection of the extraction solvent. While waiting for the solvent to be prepared, the internal solvent can be observed through the observation window 13.

[0063] When the configuration is completed, the tap 8 is turned on to allow the extract to flow out. At this time, because the osmanthus raw material is crushed, it is in a state of fine particles floating on the surface of the liquid. As the extract flows out, a small part of the osmanthus residue is retained on the surface of the guide plate 10, and the remaining part flows into the surface of the filter plate 61 with the liquid. The extract flows to the lower side on the surface of the filter plate 61 due to gravity. In this process, the osmanthus residue on the surface of the liquid floats up and down inside the liquid due to the flow, and then contacts and is retained by the baffle 63. As the extract flows out completely, the osmanthus residue is retained on the surface of the filter plate 61 and the guide plate 10. By physically crushing the osmanthus raw material to fully mix it with the extraction solvent, the extraction effect is achieved, the mass loss of the extract caused by the conventional distillation end is avoided, and the purity of the extract is effectively improved.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
