Description

Technical Field

[0001] The present invention relates to the field of extraction and separation devices, and particularly to a high-efficiency extraction and separation device for gardenia fruit oil. Background Art

[0002] Supercritical fluid extraction equipment uses supercritical fluid as a solvent to extract specific components from solids or liquids. A supercritical fluid refers to a fluid state formed when a substance exceeds its critical temperature and critical pressure. At this time, the fluid has unique physical and chemical properties, such as a density and solubility ability between those of a gas and a liquid. The most commonly used supercritical fluid is carbon dioxide because it has a relatively low critical temperature and pressure, is environmentally friendly, and non-toxic.

[0003] Supercritical fluid extraction technology is an efficient and environmentally friendly extraction technology, which is widely used in industries such as food, medicine, and chemical engineering. The advantages of this technology include high selectivity, high efficiency, environmental friendliness, and low energy consumption. Supercritical fluid extraction equipment generally includes an extraction tank, a compressor, a heating system, a separation system, and a circulation system. The extraction tank is used to load the material to be extracted and the supercritical fluid. The compressor is used to compress the fluid to the supercritical state. The heating system is used to adjust the temperature of the fluid above the supercritical temperature. The separation system is used to separate the extracted fluid from the extract, and usually includes one or more separation tanks. The circulation system is used to recycle the supercritical fluid to improve efficiency and reduce costs. The design and operation of supercritical fluid extraction equipment require precise control of temperature and pressure to ensure that the fluid is in the supercritical state and can efficiently complete the extraction process.

[0004] In the process of extracting components from gardenia or various plant raw materials, although the special properties of supercritical fluid result in strong flow and penetration effects, the characteristics of a single supercritical fluid input position lead to poor extraction efficiency; while adding a stirring member in the extraction tank makes the sealing structure complex and prone to sealing failure. Summary of the Invention

[0023] Referring to Figures 1 to 8 , in an embodiment of the present invention, an efficient extraction and separation device for gardenia fruit oil includes: The extraction barrel 100 includes, from top to bottom, a connected working section barrel 110, a funnel-shaped material discharging section barrel 120, and a cylindrical material discharging section barrel 130. An outlet 131 is provided on the material discharging section barrel 130. The upper cover 200 is closed at the top of the extraction barrel 100. The bottom cover 300 is closed at the bottom of the material discharging section barrel 130. The partition plate 400 is fixedly separated in the middle of the height of the working section barrel 110. A first air inlet 111 is provided above the partition plate 400 in the working section barrel 110, and a first air outlet 112 and a feed inlet 113 are provided below the partition plate 400. The magnetic stirring part includes a driving motor 510 provided on the upper cover 200 and a stirring assembly 520 provided in the extraction barrel 100. An outer magnetic action head 511 is driven at the output end of the driving motor 510. The stirring assembly 520 includes a rotating shaft 521 extending from the upper cover 200 into the material discharging section barrel 130. The upper end of the rotating shaft 521 is an inner magnetic action head 522 that acts with the outer magnetic action head 511. A transition channel 523 is provided in the rotating shaft 521 in terms of length. A plurality of stirring tubes 525 are provided on the outer wall of the rotating shaft 521 corresponding to the lower part of the partition plate 400. The stirring tubes 525 communicate with the transition channel 523. A spiral structure 526 that forms a fit is provided on the outer wall of the rotating shaft 521 corresponding to the material discharging section barrel 120 and the material discharging section barrel 130. Among them, at the position above the partition plate 400, an upper air duct 524 that communicates with the transition channel 523 is provided on the outer wall of the rotating shaft 521 or the outer wall of the inner magnetic action head 522.

[0024] In the prior art, during the process of extracting components from gardenia or various plant raw materials, although the special characteristics of supercritical fluids make the effects of flow and penetration stronger, the characteristics of a single supercritical fluid input position result in poor extraction efficiency. And when adding a stirring member in the extraction tank, while the sealing structure is complex, it is also prone to sealing failure.

[0025] The high-efficiency extraction and separation equipment for gardenia fruit oil provided by the present invention includes an extraction barrel 100, an upper cover 200, a bottom cover 300, a partition plate 400, and a magnetic stirring part.

[0026] The extraction barrel 100 includes, from top to bottom, a connected working section barrel 110, a funnel-shaped material discharging section barrel 120, and a cylindrical material discharging section barrel 130. The working section barrel 110, the material discharging section barrel 120, and the material discharging section barrel 130 can be an integral structure or a connecting structure. An outlet 131 is provided on the material discharging section barrel 130. The outlet 131 and the material discharging section barrel 130 can be an integral structure or a welded structure.

[0027] The upper cover 200 is closed at the top of the extraction barrel 100. The connection between the upper cover 200 and the extraction barrel 100 can be a threaded connection, a flange connection, or the like.

[0028] The bottom cover 300 is closed at the bottom of the discharge section barrel 130. The bottom cover 300 and the discharge section barrel 130 are of an integral structure or a connection structure.

[0029] The partition plate 400 is separated in the middle of the height of the working section barrel 110. The fixing method of the partition plate 400 can be various. For example, the outer periphery of the partition plate 400 is clamped by the upper cover 200 and the extraction barrel 100, or a mounting seat is provided on the extraction barrel 100, and the partition plate 400 is fixed to the mounting seat by bolts. A first air inlet 111 is provided above the partition plate 400 in the working section barrel 110. The first air inlet 111 is the position where the supercritical fluid enters, but it can also be used for other injection or discharge functions. A first air outlet 112 and a feed inlet 113 are provided below the partition plate 400 in the working section barrel 110. The first air outlet 112 is the position where the supercritical fluid is discharged, but it can also be used for other injection or discharge functions. The feed inlet 113 is the injection port for the raw material to be extracted, but it can also be used for other injection or discharge functions. The partition plate 400 divides the extraction barrel 100 into an upper space and a lower space.

[0030] The magnetic stirring part includes a driving motor 510 arranged on the upper cover 200 and a stirring assembly 520 arranged in the extraction barrel 100. The driving motor 510 can be arranged on the upper cover 200 in various ways. An outer magnetic action head 511 is driven at the output end of the driving motor 510, and it is not necessarily magnetic. The stirring assembly 520 includes a rotating shaft 521 extending from the upper cover 200 into the discharge section barrel 130. The upper end of the rotating shaft 521 is an inner magnetic action head 522 that acts with the outer magnetic action head 511. Magnetic action can occur between the inner magnetic action head 522 and the outer magnetic action head 511, so the operation of the driving motor 510 can drive the rotation of the rotating shaft 521. The power transmission of the magnetic stirring part is not the focus, and it can refer to the current existing technology. For example, one of the inner magnetic action head 522 and the outer magnetic action head 511 is a magnetic material and generates magnetic attraction with the other, or both the inner magnetic action head 522 and the outer magnetic action head 511 are magnetic materials, so that they can attract each other. The material of the upper cover 200 needs to be considered to avoid the situation of magnetic field shielding. Corresponding to the inner magnetic action head 522 and the outer magnetic action head 511 on the upper cover 200, a traditional bowl-shaped convex structure can be set, or other structural settings can be made, which is not the focus here. A transition channel 523 is provided in the rotating shaft 521 in terms of length. The transition channel 523 can penetrate the height direction of the inner magnetic action head 522 or be closed by the inner magnetic action head 522, and the specific setting is selected according to the actual use situation. An upper air duct 524 leading to the transition channel 523 is provided at the position above the partition 400 on the outer wall of the rotating shaft 521 or the outer wall of the inner magnetic action head 522. The upper air duct 524 conducts the upper space of the extraction barrel 100 to the transition channel 523. A plurality of stirring pipes 525 are arranged on the outer wall of the rotating shaft 521 corresponding to the lower part of the partition 400, and the stirring pipes 525 are conducted to the transition channel 523. Thus, a conduction is formed between the upper spaces of the extraction barrel 100. The upper inlet is the upper air duct 524, and the lower outlet is the stirring pipe 525. A spiral structure 526 that forms a cooperation is arranged on the outer wall of the rotating shaft 521 corresponding to the lower feeding section barrel 120 and the discharge section barrel 130. During the forward rotation of the rotating shaft 521, the spiral structure 526 generates a downward driving force, and during the reverse rotation of the rotating shaft 521, the spiral structure 526 generates an upward driving force.

[0031] During the working process, first, the extraction barrel 100, the upper cover 200, the bottom cover 300, the partition plate 400, and the magnetic stirring part are all installed in place. Through the feed inlet 113 on the extraction barrel 100, the raw material to be extracted is injected into the lower space. During this process, the rotating shaft 521 rotates in the reverse direction, and the spiral structure 526 and the stirring tube 525 jointly complete the homogenization of the raw material to be extracted. After the loading is completed, supercritical fluid is injected through the first air inlet 111. The supercritical fluid enters from the upper air passage 524 of the rotating shaft 521, then is introduced into each stirring tube 525 through the transition passage 523, and finally enters the lower space of the extraction barrel 100. During the injection of the supercritical fluid, the rotating shaft 521 continuously rotates in the reverse direction. While completing the stirring action, the supercritical fluid flows out from each stirring tube 525, fully realizing the homogenization and efficient extraction process. After the extraction process is completed, after the extraction fluid is completely discharged through the first air outlet 112, the rotating shaft 521 rotates in the forward direction, and the discharge port 131 is opened. The material after extraction is automatically discharged through the operation of the stirring assembly 520. When the entire device needs to be cleaned, water is injected into the space above the partition plate 400 through the first air inlet 111 or an independently provided water inlet. The water flow enters from the upper air passage 524 of the rotating shaft 521, then is introduced into each stirring tube 525 through the transition passage 523, and finally enters the lower space of the extraction barrel 100, thereby completing the cleaning process of each part.

[0032] In summary, during the feeding process, the rotating shaft 521 rotates in the reverse direction, and the spiral structure 526 and the stirring tube 525 jointly complete the homogenization of the raw material to be extracted. The supercritical fluid enters from the upper air passage 524 of the rotating shaft 521, is introduced into each stirring tube 525 through the transition passage 523, and finally enters the lower space of the extraction barrel 100. During the injection of the supercritical fluid, the rotating shaft 521 continuously rotates in the reverse direction. While completing the stirring action, the supercritical fluid flows out from each stirring tube 525, fully realizing the homogenization and efficient extraction process. After the extraction process is completed, the rotating shaft 521 rotates in the forward direction, and the discharge port 131 is opened. The material after extraction is automatically discharged through the operation of the stirring assembly 520. When cleaning, water is injected into the space above the partition plate 400. The water flow enters from the upper air passage 524 of the rotating shaft 521, then is introduced into each stirring tube 525 through the transition passage 523, and finally enters the lower space of the extraction barrel 100, thereby completing the cleaning process of each part.

[0033] In one embodiment, an operating structure 310 for driving the stirring assembly 520 to rise and fall is connected to the bottom cover 300.

[0034] In this embodiment, the operating structure 310 can be a threaded rod, and the lifting and lowering of the stirring assembly 520 are achieved by adjusting the degree of threaded engagement between the operating structure 310 and the bottom cover 300. In other embodiments, the form of the operating structure 310 can be diverse, such as an automated structure driven by a motor.

[0035] Referring to Figure 8 , in one embodiment, when the stirring assembly 520 is in the upper state, there is a clearance fit between the rotating shaft 521 and the partition plate 400.

[0036] In this embodiment, considering that after the extraction and separation equipment has been used for a certain period of time, it is possible for a small amount of impurities to enter above the partition plate 400. Therefore, during the cleaning process, not only the space below the partition plate 400 needs to be cleaned, but also the space above the partition plate 400 needs to be cleaned. Water is injected into the space above the partition plate 400 through the first air inlet 111 or an independently provided water inlet. When the stirring assembly 520 is lifted, the small amount of impurities above the partition plate 400 fall into the lower part together with the water flow, thus completing the cleaning process. The manner in which the clearance fit between the rotating shaft 521 and the partition plate 400 is formed can be diverse. For example, the outer circumference of the rotating shaft 521 has a non-uniform diameter at this position. When the rotating shaft 521 is in the lower state, they are in close fit, and when the rotating shaft 521 is in the upper state, there is a clearance fit between them. When using the first air inlet 111 to perform the water injection operation simultaneously, relevant valve structures need to be set to selectively introduce supercritical gas and cleaning water into the first air inlet 111.

[0037] In one embodiment, the inner wall of the discharge section barrel 130 is in the shape of an inverted frustum of a cone.

[0038] In this embodiment, considering that the spiral structure 526 needs to form a driving effect, the size of the outer circumference of the spiral structure 526 and the inner wall of the extraction barrel 100 form a very precise match. The possibility of structural damage to the spiral structure 526 or the extraction barrel 100 during rotation is relatively high, especially when the rotation speed of the stirring assembly 520 is relatively high. Specifically, the taper of the inner wall of the discharge section barrel 130 is designed and selected according to the actual situation.

[0039] Referring to Figure 1 , in one embodiment, the upper cover 200 is provided with an upper convex bowl 210 at the position corresponding to the outer magnetic action head 511, and the inner magnetic action head 522 extends into the upper convex bowl 210 to form a fit.

[0040] In this embodiment, in the form of the upper convex bowl 210, the possibility of the structure of the inner magnetic action head 522 retaining impurities is reduced, and even if impurities enter the gap between the inner magnetic action head 522 and the upper convex bowl 210, they are likely to naturally escape or be washed out.

[0041] In one embodiment, a lower air passage that leads into the stirring tube 525 is provided on the outer wall of the stirring tube 525.

[0042] In this embodiment, the provision of the lower air passage can improve the dispersion efficiency of the supercritical gas, and can also improve the extraction and separation effect. At the same time, during the process of passing through the cleaning water, the lower air passage can also achieve a better cleaning effect and complete a more thorough flushing.

[0043] In one embodiment, the transition passage 523 is eccentrically arranged within the rotating shaft 521.

[0044] During the process of inputting the supercritical gas, there is no obvious difference in the fluid transmission process between the transition passage 523 on the rotating shaft 521 and each stirring tube 525, because of the fluid characteristics and high-pressure characteristics of the supercritical gas. However, during the process of conducting the cleaning water, there is a large difference in the efficiency of introducing the cleaning water into the stirring tubes 525 at different heights. In this embodiment, the transition passage 523 is eccentrically arranged in the rotating shaft 521. Then, during the rotation of the rotating shaft 521, due to the centrifugal force, the cleaning water in the transition passage 523 enters the stirring tube 525 with a higher efficiency.

[0045] Refer to Figures 1 to 4 , in one embodiment, the inner magnetic action head 522 is tightly attached to the partition plate 400. The partition plate 400 is sleeved on the rotating shaft 521 and is provided with a plurality of groove rings 410. The inner magnetic action head 522 is provided with ribbed rings 420 that form a clearance fit corresponding to the groove rings 410.

[0046] In this embodiment, through the cooperation formed between the groove rings 410 and the ribbed rings 420, a labyrinth seal structure is formed, and the possibility of related impurities entering from below the partition plate 400 to above at the position of the rotating shaft 521 is greatly reduced. Especially when the partition plate 400 is provided with a groove ring 410 structure, the cleaning process is more thorough after the inner magnetic action head 522 rises. The number of the groove rings 410 and the ribbed rings 420 is preferably three to six, which can provide a strong sealing effect while not significantly increasing the processing difficulty.

[0047] Refer to Figure 2 , in one embodiment, the outer periphery of the partition plate 400 is clamped by the working section barrel 110 and the upper cover 200 in the thickness direction.

[0048] In this embodiment, the fixing method of the partition plate 400 is restricted. The partition plate 400 is clamped by the working section barrel 110 and the upper cover 200 at the edge of the circumference, so that the sealing effect at this position is relatively good. The manner of forming the clamping structure can be various. For example, an installation step is provided on the inner wall of the working section barrel 110 to support the partition plate 400, and a fixing ring extends downward from the lower part of the upper cover 200 to press down on the partition plate 400.

[0049] In one embodiment, the rotating shaft 521 and the inner magnetic action head 522 are detachably connected.

[0050] In this embodiment, since the rotating shaft 521 and the inner magnetic action head 522 are detachably connected, the installation process of the partition plate 400 is simplified. The connection manner between the rotating shaft 521 and the inner magnetic action head 522 can be threaded connection, bolt connection or flange connection, etc.

[0051] In one embodiment, a water inlet is provided above the partition plate 400 corresponding to the working section barrel 110.

[0052] In the foregoing embodiment, the injection of cleaning water can be completed through the first air inlet 111. In this embodiment, a water inlet is independently provided to complete the water injection into the space above the partition plate 400. When the stirring assembly 520 is lifted, the trace impurities above the partition plate 400 fall into the lower part together with the water flow, thereby completing the cleaning process. Independently providing a water inlet can provide great convenience for the work.

[0053] In summary, for the high-efficiency extraction and separation equipment for gardenia fruit oil provided by the present invention, during the feeding process, the rotating shaft 521 rotates reversely, and the spiral structure 526 and the stirring tube 525 jointly complete the homogenization of the raw material to be extracted. The supercritical fluid enters from the upper air duct 524 of the rotating shaft 521, is introduced into each stirring tube 525 through the transition channel 523, and finally enters the lower space of the extraction barrel 100. During the injection process of the supercritical fluid, the rotating shaft 521 continuously rotates reversely. While completing the stirring action, the supercritical fluid flows out from each stirring tube 525, fully realizing the homogenization and high-efficiency extraction process; after the extraction process is completed, the rotating shaft 521 rotates forward, and the discharge port 131 is opened. The extracted material is automatically discharged through the work of the stirring assembly 520; during cleaning, the space above the partition plate 400 is filled with water. The water flow enters through the upper air duct 524 of the rotating shaft 521, and then is introduced into each stirring tube 525 through the transition channel 523, and finally enters the lower space of the extraction barrel 100, thereby completing the cleaning process of each part.

[0054] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
