Description

Technical Field

[0001] The invention relates to the field of garlic oil extraction, and more particularly to a device for extracting garlic oil. Background Art

[0002] Garlic oil is an important substance extracted from garlic, which has many pharmacological functions, such as activating cells, promoting energy production, enhancing antibacterial and antiviral abilities, accelerating metabolism, relieving fatigue, etc. At present, the extraction methods of garlic oil mainly include steam distillation, solvent extraction, and supercritical CO2 extraction. Supercritical fluid extraction technology (SFE) is a new separation technology that uses the characteristics of supercritical fluids (such as CO2) with low gas viscosity and high liquid solubility near the critical point to achieve efficient component extraction. The critical temperature of supercritical CO2 is 31.1℃ and the critical pressure is 7.2MPa, which is easy to realize industrialization. Its density is close to that of liquid, with extremely strong solubility, while its viscosity is close to that of gas, with high diffusion coefficient, and it can quickly penetrate materials.

[0003] The accumulation of materials in the static extraction tank leads to a single CO2 permeation path, and the garlic paste is easy to clump and form a "dead zone". Even if some equipment can turn the garlic to a certain extent, the materials near the edge are still difficult to turn completely, resulting in some materials not being fully extracted and the oil being difficult to fully dissolve. To this end, we propose a garlic oil extraction equipment. Summary of the invention

[0004] The invention provides a garlic oil extraction device, which solves the technical problem in the related art that materials close to the edge are still difficult to be completely turned over, resulting in that part of the materials cannot be fully extracted and the oil is difficult to be fully dissolved.

[0005] The present invention provides a garlic oil extraction device, comprising: an extraction tank, wherein a supercritical flow-aiding mechanism extending to the tank bottom is arranged at the center of a sealing cover of the extraction tank;

[0006] The supercritical flow-aiding mechanism comprises a vertical arm, a material-carrying part and a speed control part, wherein: the material-carrying part comprises a circular array of branch support arms and a garlic paste filter cloth, each branch support arm penetrates the vertical arm to form a sliding connection, and an air-pushing plate with an inclination angle of 15-35° is arranged on the lower surface of the branch support arm, and adjacent air-pushing plates form a staggered flow-guiding structure;

[0007] The garlic paste filter cloth is fixedly embedded in a fan shape between adjacent branch arms, and forms a filter disc matching the inner diameter of the extraction tank in the unfolded state; the speed control unit is connected to each branch arm, and drives the branch arms to alternately perform low-speed lifting and high-speed release, so that the garlic paste filter cloth forms a periodic undulating motion in a supercritical CO2 environment: the garlic paste is slowly raised by being gathered, and a free fall is triggered, and the garlic paste balls are dispersed in a weightless state.

[0008] Further, a plurality of CO2 ejection holes and lifting channels are formed in the outer wall of the vertically inserted arm. The total air inlet end of the plurality of CO2 ejection holes is provided with a CO2 supply pipe, and the plurality of CO2 ejection holes are interconnected with the CO2 supply pipe through an air channel provided in the wall plate of the vertically inserted arm.

[0009] Further, the split support arm penetrates through the lifting channel and slides up and down along it. A protective hanging curtain is slidably arranged on the inner wall of the lifting channel, and the protective hanging curtain is fixedly connected to the split support arm in a folding fan shape to prevent the garlic paste from entering the vertically inserted arm.

[0010] Further, the speed control component includes a pneumatic push rod, and the pneumatic push rod is fixed at the inner top end of the vertically inserted arm. The air inlet control end of the pneumatic push rod is connected with a push rod air supply pipe. The pneumatic push rod includes a quick extension arm, and the quick extension arm is coaxial with the vertically inserted arm. The bottom end of the quick extension arm is fixedly connected to a plurality of split support arms.

[0011] Further, a plurality of ultrasonic generators are fixedly arranged on the upper walls of the plurality of split support arms. The ultrasonic emission direction of the ultrasonic generators is vertically upward, and the ultrasonic generators are connected to and controlled by the intelligent module.

[0012] Further, arc-shaped auxiliary support rings are fixedly arranged on the arc-shaped edges of the plurality of garlic paste filter cloths. Both ends of the plurality of auxiliary support rings are fixedly connected to the side walls of two adjacent split support arms.

[0013] Further, the split support arms and the auxiliary support rings are used to support the stability of three sides of the garlic paste filter cloth, so that the center of the garlic paste filter cloth is in a sunken state after being affected by gravity.

[0014] Further, an outer ring pipe is fixedly arranged on the outer periphery of the bottom ring of the extraction tank. The output end of the outer ring pipe is fixedly connected with a gas-liquid outlet for discharging supercritical CO2 for pressure relief.

[0015] Further, a plurality of floating balls are arranged at the input end of the outer ring pipe. The plurality of floating balls are located in the extraction tank, and the plurality of floating balls are interconnected with the outer ring pipe through a connecting pipe and are distributed in a ring shape.

[0016] Further, an air inlet hole is formed in the top of the floating ball, a reflux hole is formed in the bottom of the floating ball, a pneumatic ball is fixedly arranged in the upper middle part of the floating ball, and a counterweight block is fixedly arranged at the bottom of the floating ball.

[0017] The beneficial effects of the present invention are as follows:

[0018] The supercritical flow-aiding mechanism of the present invention significantly improves the extraction efficiency. Its core structure is a filter disc composed of a support arm and a garlic paste filter cloth. Driven by a speed control unit, it realizes periodic undulating motion, so that the garlic paste mass alternately experiences a slow load-bearing state and a weightless dispersion state in a supercritical CO2 environment. This motion mode not only increases the contact area between the material and the supercritical fluid, but also strengthens the turbulent effect through the 15-35° inclined flow guide structure of the air push plate, thereby promoting the improvement of mass transfer efficiency. In particular, at the moment of weightlessness, the instantaneous dispersion and suspension state of the garlic paste particles enhances the penetration of the CO2 fluid in the extraction tank and increases the dissolution rate of the target component.

[0019] The alternate movement mechanism of the spreading arm driven by the speed control unit, through the periodic action of "low-speed lifting-high-speed release", innovatively uses the weightlessness effect to enhance the dispersion effect of the mashed garlic. During low-speed lifting, the spreading arm drives the filter cloth to rise slowly, so that the mashed garlic can fully absorb the extractant in the supercritical CO2 environment and gradually break away from the accumulation at the bottom of the tank; during the high-speed release stage, the spreading arm quickly returns to trigger the free fall of the mashed garlic, using the instantaneous weightlessness to break the mashed garlic agglomerate structure and promote particle dispersion. This dynamic undulating movement not only prevents the mashed garlic from agglomerating due to static pressure, but also increases the probability of contact between CO2 and active ingredients through mechanical-gravity synergy.

DETAILED DESCRIPTION

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a garlic oil extraction device comprises: an extraction tank 11, a supercritical flow-aiding mechanism 2 extending to the tank bottom is arranged at the center of the sealing cover of the extraction tank 11;

[0032] The supercritical flow-aiding mechanism 2 includes a vertical arm 21, a material-carrying member and a speed control member, wherein: the material-carrying member includes a ring-shaped array of branch support arms 33 and a garlic paste filter cloth 31, each branch support arm 33 penetrates the vertical arm 21 to form a sliding connection, and a push plate 38 with an inclination angle of 15-35° is arranged on the lower surface of the branch support arm 33, and adjacent push plates 38 form a staggered guide structure;

[0033] The garlic paste filter cloth 31 is fixedly embedded in a fan shape between adjacent branch arms 33, and forms a filter disc matching the inner diameter of the extraction tank 11 in the unfolded state; the speed control unit is connected to each branch arm 33, and drives the branch arms 33 to alternately perform low-speed lifting and high-speed release, so that the garlic paste filter cloth 31 forms a periodic undulating motion in the supercritical CO2 environment: the garlic paste is slowly lifted up by the folding, and the free fall is triggered, and the garlic paste balls are dispersed in a weightless state.

[0034] The outer wall of the vertical arm 21 is provided with a plurality of CO2 ejection holes 24 and a lifting channel 23, and a CO2 supply pipe 22 is provided at the total air inlet end of the plurality of CO2 ejection holes 24, and the plurality of CO2 ejection holes 24 are interconnected with the CO2 supply pipe 22 through an air channel provided in the wall panel of the vertical arm 21.

[0035] like Figure 5 ,Figure 6 and Figure 7 As shown in Figure 7 , the split support arm 33 penetrates through the lifting channel 23 and slides up and down along it. A protective hanging curtain 25 is slidably arranged on the inner wall of the lifting channel 23, and the protective hanging curtain 25 is fixedly connected to the split support arm 33 in a folding fan shape, and is used to block the garlic puree from entering the hanging arm 21.

[0036] The speed control component includes a pneumatic push rod 36, and the pneumatic push rod 36 is fixed at the inner top end of the hanging arm 21. The air inlet control end of the pneumatic push rod 36 is connected with a push rod air supply pipe 35. The pneumatic push rod 36 includes a quick extension arm 37, and the quick extension arm 37 is coaxial with the hanging arm 21. The bottom end of the quick extension arm 37 is fixedly connected to a plurality of split support arms 33.

[0037] A plurality of ultrasonic generators 34 are fixedly arranged on the upper walls of a plurality of split support arms 33. The ultrasonic emission direction of the ultrasonic generator 34 is vertically upward, and the ultrasonic generator 34 is connected to and controlled by the intelligent module.

[0038] Arc-shaped auxiliary support rings 32 are fixedly arranged on the arc-shaped edges of a plurality of garlic puree filter cloths 31. Both ends of a plurality of auxiliary support rings 32 are fixedly connected to the side walls of two adjacent split support arms 33.

[0039] The split support arm 33 and the auxiliary support ring 32 are used to support the stability of three sides of the garlic puree filter cloth 31, so that the center of the garlic puree filter cloth 31 is in a sunken state under the action of gravity.

[0040] As Figure 2 、 Figure 8 and Figure 9 As shown in Figure 2 , Figure 8 and Figure 9 , an outer ring pipe 41 is fixedly arranged on the outer periphery of the bottom ring of the extraction tank 11. The output end of the outer ring pipe 41 is fixedly connected with a gas-liquid outlet 42, which is used for pressure relief and discharging supercritical CO2.

[0041] A plurality of floating balls 43 are arranged at the input end of the outer ring pipe 41. A plurality of floating balls 43 are located in the extraction tank 11, and a plurality of floating balls 43 are communicated with the outer ring pipe 41 through a connecting pipe and are distributed in a ring shape.

[0042] An air inlet hole 45 is opened at the top of the floating ball 43, a reflux hole 46 is opened at the bottom of the floating ball 43, a pneumatic ball 44 is fixedly arranged in the upper middle part of the floating ball 43, and a counterweight 47 is fixedly arranged at the bottom of the floating ball 43.

[0043] First, lift the sealing cover of the extraction tank 11 upward by a certain height, then add the garlic puree raw material into the extraction tank 11. A large amount of garlic puree is distributed on the garlic puree filter cloth 31, and then close the sealing cover. At this time, a large amount of garlic puree is at the bottom of the extraction tank 11 along with the garlic puree filter cloth 31;

[0044] After that, the extraction tank 11 starts to work. When it reaches the preset state, carbon dioxide is injected into the air duct opened in the wall plate of the vertical arm 21 through a carbon dioxide supply device externally connected to the CO2 supply pipe 22, and then diffuses into the extraction tank 11 through multiple CO2 ejection holes 24;

[0045] Subsequently, the extraction tank 11 can be pressurized to make the carbon dioxide in the extraction tank 11 in a supercritical state. At this time, the intelligent module controls the pneumatic push rod 36 to work, so that the telescopic arm 37 expands and contracts. The telescopic arm 37 drives the supporting arm 33 and the garlic puree filter cloth 31 to slowly rise. At this time, the supporting arm 33 closes to carry the garlic puree and slowly rises, and the air pushing plate 38 guides the supercritical fluid to form a vortex flow;

[0046] When the supporting arm 33 reaches the preset height, the supporting arm 33 is controlled by the pneumatic push rod 36 to quickly descend. At this time, the descending speed of the garlic puree filter cloth 31 is greater than the free-fall speed of the garlic puree, and the garlic puree falls freely. The garlic puree mass disperses under the weightless state. The air pushing plate 38 cuts the fluid to generate turbulence. The supporting arm 33 drives the garlic puree filter cloth 31 to perform a reciprocating motion of slow rise and rapid descent, so that the garlic puree in the filter cloth forms a dense accumulation layer during the slow rise stage, and realizes vibration dispersion during the free-fall stage, strengthening the contact and penetration of the supercritical fluid with the garlic puree and the material vibration mixing effect. When the garlic puree falls freely, it also plays a role of strong impact;

[0047] While the garlic puree filter cloth 31 slowly rises and quickly descends, multiple ultrasonic generators 34 also work, and the sound waves emitted by the ultrasonic waves spread vertically upward and impact on the garlic puree;

[0048] When the extraction time reaches the preset time, the extraction tank 11 is still in the carbon dioxide supercritical state. The staff opens the valve of the gas-liquid outlet 42, and the supercritical state carbon dioxide carries the garlic oil and is discharged through the air inlet hole 45 and the outer ring pipe 41, and then subsequent fine processing is carried out.

[0049] After the garlic puree filter cloth 31 carries the garlic puree and rises, if there is liquid in the garlic puree, under the vibration of multiple rises and descents, a large amount of water can be shaken off to the bottom of the extraction tank 11, thereby reducing the contact between the carbon dioxide in the supercritical state and the water in the garlic puree;

[0050] If there is liquid at the bottom, the floating ball 43 can float on the liquid by means of the pneumatic ball 44. Under the action of the counterweight 47, the air inlet hole 45 is always above the liquid, which will not affect the gas flow. Even if liquid enters the floating ball 43, it can be discharged from the reflux hole 46.

[0051] Equipment initialization and raw material loading

[0052] Sealing Cover Lifting Mechanism: Driven by hydraulic or pneumatic means, the sealing cover rises vertically by 30 - 50 cm to form an open feeding port, ensuring that the garlic puree is evenly distributed on the surface of the garlic puree filter cloth 31, and the initial stacking thickness is controlled at 8 - 12 cm.

[0053] Filter Cloth Prefabrication Technology: The auxiliary support ring 32 and the sub - support arm 33 are made of alloy materials. In the initial state, the central depression depth of the garlic puree filter cloth 31 is ≥5 cm, forming a natural diversion channel, which is conducive to the rapid penetration of supercritical CO2.

[0054] Establishment of Supercritical Environment

[0055] CO2 Diffusion System: The CO2 ejection holes 24 of the vertical arm 21 are symmetrically distributed, and the hole spacing is from the bottom to the top of the tank to ensure uniform distribution of fluid density.

[0056] Dynamic Pressure Regulation: Through the PLC control system, at the initial stage of extraction, the pressure is increased step - by - step to the target pressure to avoid the destruction of the garlic puree structure caused by pressure shock.

[0057] Ultrasonic - assisted Extraction

[0058] Acoustic Wave Focusing Technology: The acoustic waves of the ultrasonic generator 34 are reflected by the sub - support arm 33 to form a focusing area on the surface of the filter cloth. The high - speed micro - jets generated by the cavitation effect can penetrate the garlic puree mass, improving the cell wall breaking rate.

[0059] Frequency Modulation Strategy: Adopt a 20kHz / 40kHz dual - frequency alternating mode. The low - frequency 20kHz generates a strong cavitation effect, and the high - frequency 40kHz enhances the thermal effect. The alternating period is 10 seconds, improving the comprehensive extraction efficiency.

[0060] Filter Cloth Movement Control

[0061] Kinematic Model of Quick - control Component: The pneumatic push rod 36 adopts a cylinder structure, and the movement of the quick - extension arm 37 is divided into three stages:

[0062] Slow Lift 0 - 8 s: The speed is 0.2 m / s to ensure the complete rise of the garlic puree mass.

[0063] Emergency Stop Transition 8 - 9 s: The speed drops suddenly to 0, forming an instantaneous negative pressure area, triggering the expansion of micro - cracks on the surface of the garlic puree mass.

[0064] Free Fall 9 - 10 s: The filter cloth is completely released, and the falling acceleration reaches 9.8 m / s², and the garlic puree mass is dispersed under weightless conditions.

[0065] Hydrodynamics Optimization: The 15 - 35° inclination angle design of the gas - pushing plate 38 guides CO2 to form a spiral upward flow during the rising stage, increasing the shear force; a reverse turbulent flow is generated during the falling stage, improving the mass transfer coefficient.

[0066] Dynamic Separation and Drainage

[0067] Work in coordination with the floating ball 43: The floating ball 43 adopts a double-layer structure, with the outer layer made of corrosion-resistant fluororubber and the inner layer being the pneumatic ball 44.

[0068] Slow-rise - rapid-drop motion mechanism: The periodic motion of the split support arm 33 enables the mashed garlic to experience a cycle of "dense packing - weightlessness dispersion". During the slow-rise stage, a high-pressure penetration environment is formed, facilitating the penetration of CO2 through the dense material layer; the vibration dispersion during the rapid-drop stage breaks the material agglomeration, exposes the fresh active surface, and the extraction rate is increased by %.

[0069] Flow guiding design of the air-pushing plate 38: The staggered flow guiding structure enables the supercritical fluid to generate an alternating flow state of vortices and turbulence, increases the fluid shear force, effectively reduces the boundary layer thickness, and increases the mass transfer coefficient.

[0070] Improvement of cell wall breaking rate: The cavitation bubbles generated by the ultrasonic generator 34 can generate local high temperature and high pressure instantaneously when they collapse, destroying the fiber structure of the garlic cell wall and increasing the oil release rate.

[0071] Enhancement of microporous penetration: High-frequency vibration makes it easier for CO2 molecules to enter the internal micropores of the material, shortens the extraction time, and reduces the solvent consumption.

[0072] Intelligent phase separation of the floating ball 43: The dynamic balance design of the pneumatic ball 44 and the counterweight 47 ensures that the air inlet 45 is always above the gas-liquid interface, preventing moisture from mixing into the extract. Compared with the traditional fixed outlet, the product purity is improved, and the subsequent rectification energy consumption is reduced.

[0073] Energy-saving design of the speed control component: The pneumatic push rod 36 adopts a driving mode of "low-speed energy consumption - high-speed potential energy release".

[0074] Reliability guarantee of the protective curtain 25: The fan-shaped curtain expands and contracts synchronously when the split support arm 33 moves, effectively preventing the mashed garlic from blocking the lifting channel 23 and reducing the equipment failure rate.

[0075] Three-sided support filter cloth system: The split support arm 33 and the auxiliary support ring 32 form a triangular stable support, and the center of the filter cloth naturally sags to form a depression, avoiding stress concentration caused by the impact of the supercritical fluid and prolonging the service life of the filter cloth.

[0076] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
