Description

Technical Field

[0001] The invention relates to the field of extraction and separation devices, and in particular 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 is a substance in a fluid state formed when its critical temperature and critical pressure exceed its critical value. At this point, the fluid exhibits unique physical and chemical properties, such as density and solubility between those of gases and liquids. The most commonly used supercritical fluid is carbon dioxide due to its low critical temperature and pressure, environmental friendliness, and non-toxicity.

[0003] Supercritical fluid extraction technology is an efficient and environmentally friendly extraction technology that is widely used in the food, pharmaceutical, chemical and other industries. The advantages of this technology include high selectivity, high efficiency, environmental protection and low energy consumption. Supercritical fluid extraction equipment usually 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 a supercritical state. The heating system is used to adjust the temperature of the fluid to 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 a supercritical state and can efficiently complete the extraction process.

[0004] In the process of extracting ingredients from gardenia or various plant materials, although the special characteristics of supercritical fluid make the flow and penetration effects stronger, the characteristics of the single supercritical fluid input position make the extraction efficiency poor; and adding a stirring component in the extraction tank not only complicates the sealing structure, but also makes it easy for the seal to fail.

[0035] Reference Figures 1 to 8 In one embodiment of the present invention, a highly efficient extraction and separation device for gardenia fruit oil comprises:

[0036] The extraction barrel 100 includes, from top to bottom, a connected working section barrel 110, a funnel-shaped discharge section barrel 120, and a cylindrical discharge section barrel 130, wherein the discharge section barrel 130 is provided with a discharge port 131;

[0037] An upper cover 200 is sealed on the top of the extraction barrel 100;

[0038] A bottom cover 300 is sealed at the bottom of the discharge barrel 130;

[0039] A partition 400 is fixedly separated at the middle of the height of the working section barrel 110. The working section barrel 110 is provided with a first air inlet 111 above the partition 400 and a first air outlet 112 and a feed port 113 below the partition 400.

[0040] 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 output end of the driving motor 510 drives an external magnetic action head 511. 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 internal magnetic action head 522 that acts on the external magnetic action head 511. A transition channel 523 is provided on the inner length of the rotating shaft 521. The rotating shaft 521 is provided with a plurality of stirring tubes 525 on the outer wall corresponding to the bottom of the partition 400, and the stirring tubes 525 are connected to the transition channel 523. The rotating shaft 521 is provided with a matching spiral structure 526 on the outer wall corresponding to the lower material section barrel 120 and the discharge material section barrel 130, wherein, at the upper position of the partition 400, the outer wall of the rotating shaft 521 or the outer wall of the inner magnetic action head 522 is provided with an upper airway 524 connected to the transition channel 523.

[0041] In the prior art, during the extraction of components from gardenia or various plant materials, although the special properties of supercritical fluids result in strong flow and penetration effects, the characteristics of a single supercritical fluid input position result in poor extraction efficiency. Adding a stirring member to the extraction tank complicates the sealing structure and is also prone to seal failure.

[0042] The high-efficiency extraction and separation equipment for gardenia fruit oil provided by the present invention comprises an extraction barrel 100, an upper cover 200, a bottom cover 300, a partition 400 and a magnetic stirring part.

[0043] From top to bottom, the extraction barrel 100 comprises a connected working section barrel 110, a funnel-shaped discharge section barrel 120, and a cylindrical discharge section barrel 130. The working section barrel 110, the discharge section barrel 120, and the discharge section barrel 130 can be integrally formed or connected. The discharge section barrel 130 is provided with a discharge port 131. The connection between the discharge port 131 and the discharge section barrel 130 can be integrally formed or welded.

[0044] The upper cover 200 is sealed on the top of the extraction barrel 100. The upper cover 200 and the extraction barrel 100 can be connected by threads or flanges.

[0045] The bottom cover 300 is sealed at the bottom of the discharge section barrel 130. The bottom cover 300 and the discharge section barrel 130 are an integral structure or a connected structure.

[0046] A partition 400 is located midway along the height of the working section barrel 110. The partition 400 can be secured in various ways, such as by having the outer periphery of the partition 400 clamped between the upper cover 200 and the extraction barrel 100, or by providing a mounting base on the extraction barrel 100 to which the partition 400 is bolted. A first air inlet 111 is provided above the working section barrel 110, corresponding to the partition 400. This first air inlet 111 serves as the entry point for the supercritical fluid, but it can also serve other injection or removal functions. A first air outlet 112 and a feed inlet 113 are provided below the working section barrel 110, corresponding to the partition 400. This first air outlet 112 serves as the exit point for the supercritical fluid, but it can also serve other injection or removal functions. The feed inlet 113 is the inlet for the raw material to be extracted, but it can also serve other injection or removal functions. The partition 400 divides the extraction barrel 100 into an upper space and a lower space.

[0047] The magnetic stirring part includes a drive motor 510 provided on the upper cover 200 and a stirring assembly 520 provided in the extraction barrel 100. The drive motor 510 can be provided on the upper cover 200 in a variety of ways. The output end of the drive motor 510 drives an external magnetic action head 511, which is not limited to being 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 internal magnetic action head 522 that acts on the external magnetic action head 511. The internal magnetic action head 522 and the external magnetic action head 511 can act magnetically, so the operation of the drive motor 510 can drive the rotation of the rotating shaft 521. The power transmission of the magnetic stirring unit is not a key issue; reference can be made to existing technologies. For example, if one of the inner magnetic action head 522 and the outer magnetic action head 511 is made of a magnetic material and magnetically attracts the other, or if both are magnetic materials, attracting each other, the material of the upper cover 200 needs to be considered to avoid magnetic field shielding. The upper cover 200 can be provided with a conventional bowl-shaped protrusion corresponding to the inner magnetic action head 522 and the outer magnetic action head 511, or other structural configurations can be employed, which are not the focus here. A transition channel 523 is provided along the inner length of the rotating shaft 521. The transition channel 523 can extend through the height of the inner magnetic action head 522 or be enclosed by the inner magnetic action head 522, depending on the actual use. An upper airway 524 is provided on the outer wall of the rotating shaft 521 or the outer wall of the inner magnetic action head 522, above the partition 400, to connect to the transition channel 523. The upper airway 524 connects the upper space of the extraction barrel 100 with the transition channel 523. The outer wall of the rotating shaft 521, corresponding to the space below the partition 400, is equipped with multiple stirring tubes 525, which connect to the transition channel 523. This creates a connection between the upper spaces of the extraction barrel 100, with the upper inlet forming the upper airway 524 and the lower outlet forming the stirring tubes 525. The rotating shaft 521 is equipped with a mating spiral structure 526 on the outer walls of the lower and discharge barrels 120, 130. During forward rotation of the rotating shaft 521, the spiral structure 526 generates a downward driving force, while during reverse rotation, the spiral structure 526 generates an upward driving force.

[0048] During operation, first install the extraction barrel 100, the upper cover 200, the bottom cover 300, the partition 400 and the magnetic stirring part in place. The raw material to be extracted is injected into the lower space through the feed port 113 on the extraction barrel 100. During this process, the rotating shaft 521 rotates in the opposite 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, the supercritical fluid is injected through the first air inlet 111. The supercritical fluid enters from the upper airway 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. During the supercritical fluid injection process, the rotating shaft 521 continues to rotate in the opposite 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 complete and the extracted fluid is completely discharged through the first air outlet 112, the rotating shaft 521 rotates forward, opening the discharge port 131. The extracted material is then automatically discharged through the operation of the stirring assembly 520. To clean the entire apparatus, water is injected into the space above the partition 400 through the first air inlet 111 or a separately provided water inlet. The water enters through the upper air passage 524 of the rotating shaft 521, then flows through the transition channel 523 into the various stirring tubes 525, and finally into the lower space of the extraction barrel 100, completing the cleaning process for each component.

[0049] In summary, during the feeding process, the rotating shaft 521 rotates in the opposite direction, and the spiral structure 526 and the stirring tube 525 jointly complete the homogenization of the raw materials to be extracted. The supercritical fluid enters from the upper airway 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 supercritical fluid injection process, the rotating shaft 521 continues to rotate in the opposite direction, completing the stirring action while 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 forward and opens the discharge port 131. The extracted material is automatically discharged through the operation of the stirring assembly 520; during cleaning, water is injected into the space above the partition 400, and the water flows into the upper airway 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.

[0050] In one embodiment, the bottom cover 300 is connected to an operating structure 310 for driving the stirring assembly 520 to rise and fall.

[0051] In this embodiment, the operating structure 310 can be a threaded rod, and the stirring assembly 520 can be raised and lowered by adjusting the degree of threaded engagement between the operating structure 310 and the bottom cover 300. In other embodiments, the operating structure 310 can be in various forms, such as a motor-driven automated structure.

[0052] Reference Figure 8 In one embodiment, the stirring assembly 520 is in an upward state, and there is a clearance fit between the rotating shaft 521 and the partition 400.

[0053] In this embodiment, considering that after the extraction and separation equipment has been used for a certain period of time, trace impurities may enter the space above the partition 400. Therefore, during the cleaning process, it is necessary not only to clean the space below the partition 400, but also to clean the space above the partition 400. Water is injected into the space above the partition 400 through the first air inlet 111 or an independently set water inlet. When the stirring assembly 520 is lifted, the trace impurities above the partition 400 fall into the bottom together with the water flow, thereby completing the cleaning process. The above-mentioned gap fit between the rotating shaft 521 and the partition 400 can be formed in various ways. For example, the diameter of the outer periphery of the rotating shaft 521 at this position is non-uniform. When the rotating shaft 521 is in the lower state, the two are tightly fitted. When the rotating shaft 521 is in the upper state, the two are gap-fitted. When the first air inlet 111 is used for water injection at the same time, a relevant valve structure needs to be provided to selectively introduce supercritical gas and cleaning water to the first air inlet 111.

[0054] In one embodiment, the inner wall of the discharge barrel 130 is in the shape of an inverted frustum.

[0055] In this embodiment, to ensure the driving effect of the spiral structure 526, the outer circumference of the spiral structure 526 is precisely aligned with the inner wall of the extraction barrel 100. This increases the likelihood of structural damage to the spiral structure 526 or the extraction barrel 100 during rotation, particularly when the stirring assembly 520 rotates at high speeds. Specifically, the taper of the inner wall of the discharge barrel 130 is designed and selected based on actual conditions.

[0056] Reference Figure 1 In one embodiment, the upper cover 200 is provided with an upper convex bowl 210 at a 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.

[0057] In this embodiment, the upper convex bowl 210 reduces the possibility of impurities being retained in the structure of the inner magnetic action head 522, and even if impurities enter the gap between the inner magnetic action head 522 and the upper convex bowl 210, they can be easily removed naturally or cleaned out.

[0058] In one embodiment, a lower air passage leading to the interior of the stirring tube 525 is provided on the outer wall of the stirring tube 525 .

[0059] In this embodiment, the setting of the downcomer can improve the dispersion efficiency of the supercritical gas and the extraction and separation effect. At the same time, the downcomer can also achieve a better cleaning effect when clean water passes through it, completing a more thorough flushing.

[0060] In one embodiment, the transition channel 523 is eccentrically disposed within the rotating shaft 521 .

[0061] During the supercritical gas input process, there is no significant difference in the fluid transfer process between the transition channel 523 on the rotating shaft 521 and the various stirring tubes 525 due to the fluid and high-pressure characteristics of supercritical gas. However, during the clean water flow process, the efficiency of clean water introduction into the stirring tubes 525 at different heights varies significantly. In this embodiment, the transition channel 523 is eccentrically positioned relative to the rotating shaft 521. As the rotating shaft 521 rotates, the centrifugal effect increases the efficiency of clean water entering the stirring tubes 525 from the transition channel 523.

[0062] Reference Figures 1 to 4 In one embodiment, the inner magnetic action head 522 is tightly arranged with the partition 400, the partition 400 is sleeved with the rotating shaft 521 and is provided with a plurality of groove rings 410, and the inner magnetic action head 522 is provided with a ridge ring 420 corresponding to the groove ring 410 to form a clearance fit.

[0063] In this embodiment, the cooperation between the groove ring 410 and the ridge ring 420 forms a labyrinth seal structure, significantly reducing the possibility of impurities entering from below the partition 400 at the location of the rotating shaft 521. Particularly, the partition 400 is configured with the groove ring 410 structure, which ensures a more thorough cleaning process after the internal magnetic action head 522 is raised. The number of groove rings 410 and ridge rings 420 is preferably three to six, providing a strong sealing effect while minimizing the processing difficulty.

[0064] Reference Figure 2 In one embodiment, the outer periphery of the partition 400 is clamped by the working section barrel 110 and the upper cover 200 in the thickness direction.

[0065] In this embodiment, the partition 400 is secured in a limited manner, being clamped by the working section barrel 110 and the upper cover 200 at the edge of the peripheral channel, thereby achieving a better sealing effect at this location. The clamping structure can be formed in various ways, such as providing mounting steps on the inner wall of the working section barrel 110 to support the partition 400, and a fixing ring extending downward from the lower portion of the upper cover 200 to press down the partition 400.

[0066] In one embodiment, the rotating shaft 521 and the inner magnetic action head 522 are detachably connected.

[0067] In this embodiment, the installation process of the partition 400 is simplified by detachably connecting the rotating shaft 521 and the inner magnetic action head 522. The connection between the rotating shaft 521 and the inner magnetic action head 522 can be a thread, a bolt, or a flange connection.

[0068] In one embodiment, the working section barrel 110 is provided with a water inlet above the partition 400 .

[0069] In the previous embodiment, cleaning water can be injected through the first air inlet 111. In this embodiment, a separate water inlet is provided to fill the space above the partition 400 with water. When the stirring assembly 520 is raised, trace impurities above the partition 400 fall below along with the water flow, thus completing the cleaning process. The separate water inlet provides greater convenience for work.

[0070] In summary, the efficient extraction and separation equipment for gardenia fruit oil provided by the present invention, during the feeding process, the rotating shaft 521 rotates in the opposite direction, and the spiral structure 526 and the stirring tube 525 jointly complete the homogenization of the raw material to be extracted, and the supercritical fluid enters from the upper airway 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 supercritical fluid injection process, the rotating shaft 521 continues to rotate in the opposite direction, completing the stirring action while 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 forward and opens the discharge port 131. The extracted material is automatically discharged by the operation of the stirring assembly 520; during cleaning, water is injected into the space above the partition 400, and the water flows into the upper airway 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.
