Description

Technical Field

[0001] This invention relates to the technical field of matsutake mycelium extraction, and in particular to a matsutake mycelium extraction device and extraction method. Background Technology

[0002] Matsutake mushroom mycelium can synthesize and accumulate functional oils in the form of lipid droplets during fermentation. These oils are rich in unsaturated fatty acids and have extremely high development value. However, the current industrialization of oil extraction from mycelium is severely limited by outdated extraction processes and equipment.

[0003] Currently, industrial production equipment for extracting oil components from matsutake mycelium has a fragmented extraction and separation process, resulting in a lengthy and inefficient process. Furthermore, the materials are easily contaminated during transfer, leading to oxidative rancidity of the oil. Furthermore, the limited functionality of the equipment makes it impossible to grade the quality of the extract, making it difficult to enrich different fatty acid compositions or active ingredients, resulting in uneven quality and significant differences in bioactivity of the final oil products.

[0013] Preferably, an opening mechanism is provided between the vessel lid and the reactor body. The opening mechanism includes a telescopic switch mechanism located on the outside of the reactor body and a connecting rod assembly connecting the vessel lid and the telescopic switch mechanism. The connecting rod assembly includes a connecting piece fixedly installed on the outside of the reactor body, and the cylinder end of the telescopic switch is hinged to the connecting piece via a rotating shaft; The linkage assembly also includes a support plate fixedly mounted on the vessel lid and a lifting rod. The middle part of the lifting rod is hinged to the support plate via a pivot to form a lever structure. One end of the lever is connected to the end cap of the vessel lid, and the other end is movably connected to the end of the telescopic rod of the telescopic switch via a pivot.

[0015] The beneficial effects of the matsutake mycelium extraction device and extraction method disclosed in this invention are: 1. This invention achieves oil extraction, extrusion, and cleaning within a closed system by using a liftable screen tank and a chamber isolation system consisting of an upper baffle ring, a lower sealing baffle ring, and a horizontal partition. This significantly shortens the production cycle and fundamentally avoids the risks of organic solvent evaporation, oil oxidation, and external contamination caused by material transfer. Physical extrusion is achieved through a contoured extrusion head driven by an extrusion telescopic press, which can efficiently recover the high-concentration oil solution adsorbed in the residue. The extruded liquid is then separated from the main extract collected through the extract outlet. This not only significantly improves the total oil yield but also facilitates subsequent graded refining. 2. The synergistic effect of the ultrasonic oscillator and the extrusion effectively prevents the filter pores of the sieve from being blocked by lipids or cell residues. The combination of the stirring blades and the bubbler (under the protection of inert gas) enhances the mass transfer efficiency between the organic solvent and mycelium in the extraction chamber. The precise temperature control provided by the jacket and the jacket guide plate provides a key guarantee for protecting heat-sensitive components such as unsaturated fatty acids in the oil and controlling the solvent temperature. The synergistic effect of the whole system ultimately achieves efficient, high-yield and high-quality extraction of matsutake mycelium oil. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] In the accompanying drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this invention, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0020] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0021] In this embodiment: Reference Figures 1-2 The diagram shows a preferred embodiment of the present invention.

[0022] This embodiment of a matsutake mycelium extraction device includes a reaction vessel body 1, a vessel cover 2, and a jacket 3 disposed inside the reaction vessel body 1. The vessel cover 2 is provided with a manhole 25 and a lamp hole 27 for easy operation, observation, and equipment maintenance. It also includes: The sieve tank 4 has a filter structure with filter holes on its cylindrical wall, which is used to collect the mycelium of pine mushrooms; A horizontal partition 14 is fixedly installed in the middle of the inner cavity of the reactor body 1, dividing the inner cavity into an upper squeezing and cleaning chamber 15 and a lower extraction chamber 16. The center of the horizontal partition 14 is provided with a channel for the sieve tank 4 to pass through. The upper baffle ring 244 and the lower sealing baffle ring 245 can both be vertically moved and installed inside the reactor body 1, and are located above and below the horizontal partition 14, respectively. A lifting mechanism is provided on the vessel lid 2 to drive the vertical movement of the upper retaining ring 244 and the lower sealing retaining ring 245; The sieve tank 4 is disposed between the upper retaining ring 244 and the lower sealing retaining ring 245; When the device is in the squeezing and cleaning position, the screen tank 4 is located in the squeezing and cleaning chamber 15, and the lower sealing ring 245 rises and seals against the lower surface of the horizontal partition 14 to form a closed squeezing and cleaning chamber. When the device is in the extraction position, the sieve tank 4 is located in the extraction chamber 16, and the upper baffle ring 244 descends and seals against the upper surface of the horizontal partition 14 to form the extraction chamber.

[0023] Reference Figures 3-8As shown, the lifting drive mechanism includes a switching telescopic mechanism 24 disposed on the vessel cover 2. The telescopic part of the switching telescopic mechanism 24 is connected to a boom 242. The boom 242 is operatively connected to the upper retaining ring 244 and the lower sealing retaining ring 245 respectively. A sealing cavity 241 is provided outside the boom 242. A sealing end 243 extending into the interior of the reactor body 1 is provided at the bottom of the sealing cavity 241 for achieving dynamic sealing. The sealing end 243 can effectively prevent the substances inside the reactor body 1 from leaking into the external environment through the penetration part of the boom 242 during lifting and lowering activities. At the same time, it can also prevent external impurities from entering the reactor and affecting the extraction process.

[0024] The telescopic switching mechanism 24 is driven by electricity or hydraulic power, and can precisely control the movement stroke and speed of the telescopic part according to the control command, so as to ensure that the upper retaining ring 244 and the lower sealing ring 245 maintain stable and accurate positioning during vertical movement.

[0025] The lid 2 is provided with an extrusion mechanism, which includes an extrusion telescopic machine 23 installed on the lid 2 and a contour extrusion head 231 connected to the end of its telescopic part. The position of the contour extrusion head 231 corresponds to the inner cavity of the sieve tank 4 to ensure uniform force during extrusion.

[0026] Among them, the extrusion telescopic machine 23 also adopts an electric or hydraulic drive method. It can precisely control the telescopic stroke according to the preset program to moderately extrude the matsutake mycelium raw material in the screen tank 4 to promote the dissolution of functional oils.

[0027] Furthermore, the shape of the contoured extrusion head 231 is adapted to the inner cavity of the sieve tank 4, which can closely fit the surface of the raw material during the extrusion process, avoid extrusion dead corners, and improve extraction efficiency. At the same time, the extrusion mechanism and the lifting drive mechanism work together to realize the lifting and extrusion operation of the raw material at different process stages, meeting the diverse needs in the process of matsutake mycelium extraction.

[0028] Furthermore, it also includes a stirring mechanism, which includes a drive motor 26 mounted on the lid 2 and a rotating rod 261 driven by the drive motor 26 and passing through the horizontal partition 14. The portion of the rotating rod 261 located within the extraction chamber 16 is equipped with stirring blades 263. It also includes an ultrasonic cleaning and extraction mechanism, which includes an ultrasonic oscillating rod 262 mounted on the portion of the rotating rod 261 located within the extrusion cleaning chamber 15. The drive motor 26 ensures that the rotating rod 261 drives the stirring blades 263 to perform efficient stirring within the extraction chamber 16, so that the matsutake mycelium raw material and the extraction solvent are fully mixed, further improving the dissolution rate of functional oils. The ultrasonic oscillating rod 262 can generate high-frequency vibration within the extrusion cleaning chamber 15 to perform deep cleaning and vibration extraction of the raw material in the sieve tank 4, effectively removing impurities from the surface of the raw material, while enhancing the extraction effect. Working in synergy with the stirring mechanism, it improves the extraction quality and efficiency of matsutake mycelium.

[0029] Furthermore, the horizontal partition 14 is provided with a flow-guiding structure, which is connected to a squeeze liquid outlet 141 that penetrates the side wall of the reactor body 1. The bottom of the reactor body 1 is provided with an extract liquid outlet 12 and a bubbler 11 is installed to inject high-speed bubbles into the sieve tank 4 during the extraction process, thereby enhancing the extraction effect. The bubbler 11 is connected to an external inert gas (nitrogen) source through a pipe, and its outlet extends to the bottom area of ​​the sieve tank 4, which can generate uniform and fine bubbles. These bubbles will drive the extraction solvent to form a circulating flow during their ascent, which not only helps the matsutake mycelium raw material to fully contact the extraction solvent, but also accelerates the diffusion of functional oils from the raw material to the solvent and prevents oil oxidation, thereby further improving the extraction efficiency. The squeeze liquid outlet 141 is used to discharge the squeeze liquid and the waste liquid after washing, while the extract liquid outlet 12 is used to collect the final extracted matsutake mycelium extract.

[0030] In this embodiment, the inner side of the jacket 3 is provided with spirally distributed jacket guide vanes 33. The jacket 3 is provided with a jacket inlet 31 and a jacket outlet 32. The spiral guide design ensures uniform flow of the heat exchange medium. The spirally distributed jacket guide vanes 33 can ensure that the heat exchange medium circulates fully in the jacket 3, improve the heat exchange efficiency, and thus better control the temperature in the reactor. The temperature is precisely controlled below the boiling point of the organic solvent to prevent large-scale evaporation of the solvent, ensure operational safety, and maintain the optimal extraction temperature to reduce the viscosity of the oil and increase its solubility.

[0031] It is worth noting that an opening mechanism is provided between the vessel cover 2 and the reactor body 1. The opening mechanism includes a telescopic mechanism 21 located on the outside of the reactor body 1, and a connecting rod assembly connecting the vessel cover 2 and the telescopic mechanism 21. The connecting rod assembly includes a connecting piece 13 fixedly installed on the outside of the reactor body 1, and the cylinder end of the telescopic mechanism 21 is hinged to the connecting piece 13 via a rotating shaft. The connecting rod assembly also includes a support plate 211 fixedly installed on the vessel cover 2 and a lifting rod 212. The middle part of the lifting rod 212 is hinged to the support plate 211 via a rotating shaft, forming a lever structure. The mechanism has one end connected to the end cap 22 of the vessel lid 2, and the other end connected to the end of the telescopic rod of the telescopic mechanism 21 via a rotating shaft. When the telescopic mechanism 21 is started, its telescopic rod extends and retracts. Through the movable connection with one end of the lifting rod 212, the lifting rod 212 is driven to rotate around the rotating shaft hinged to the support plate 211. Since the lifting rod 212 forms a lever structure, the other end will correspondingly drive the end cap 22 of the vessel lid 2, thereby realizing the opening and closing operation of the vessel lid 2 relative to the reactor body 1. This opening mechanism is reasonably designed, convenient to operate, stable and reliable, and can effectively improve the ease of use and safety of the device.

[0032] This invention achieves material flow and workstation switching by lifting and lowering the sieve tank 4 between the extraction chamber 16 and the squeezing and cleaning chamber 15. At the extraction station, the sieve tank 4 descends, and the upper baffle ring 244 and the horizontal partition 14 seal to form the extraction chamber. At this time, the drive motor 26 drives the rotating rod 261 and the stirring blade 263 to rotate, while the bubbler 11 blows in gas. Under the precise temperature control of the jacket 3, the mycelium is efficiently extracted. The extract is collected through the extract outlet 12. After extraction, the sieve tank 4 is lifted to the squeezing and cleaning station. The lower sealing ring 245 and the horizontal partition 14 seal to form a squeezing and cleaning chamber. Then, the extrusion telescopic machine 23 drives the contour extrusion head 231 to squeeze the residue, and simultaneously starts the ultrasonic oscillating rod 262. The cavitation effect generates extremely strong micro-mechanical force, which effectively breaks the cell wall of the hyphae and releases intracellular lipid droplets. At the same time, it prevents the filter pores of the sieve from being blocked by lipids or fine particles. The squeezed liquid and the cleaning waste liquid are discharged through the squeezed liquid outlet 141, thus continuously completing the entire process of extraction, squeezing and cleaning in a closed device.

[0033] This invention achieves oil extraction, extrusion, and cleaning within a closed system by using a liftable screen tank 4 and a chamber isolation system formed by an upper baffle ring 244, a lower sealing baffle ring 245, and a horizontal partition 14. This significantly shortens the production cycle and fundamentally avoids the risks of organic solvent evaporation, oil oxidation, and external contamination caused by material transfer. Physical extrusion is achieved through a contour extrusion head 231 driven by an extrusion telescopic press 23, which efficiently recovers the high-concentration oil solution adsorbed in the residue. The oil solution is then separated from the main extract collected at the extract outlet 12 through the extrusion liquid outlet 141. This not only significantly improves the total oil yield but also facilitates subsequent graded refining.

[0034] The synergistic effect of the ultrasonic oscillator 262 and the extrusion effectively prevents the filter pores of the sieve tank 4 from being blocked by lipids or cell residues. The combination of the stirring blades 263 and the bubbler 11 (under inert gas protection) enhances the mass transfer efficiency between the organic solvent and mycelium in the extraction chamber 16. The precise temperature control provided by the jacket 3 and the jacket guide plate 33 provides a key guarantee for protecting heat-sensitive components such as unsaturated fatty acids in the oil and controlling the solvent temperature. The synergistic effect of the entire system ultimately achieves efficient, high-yield, and high-quality extraction of matsutake mycelium oil.

[0035] This embodiment also discloses a method for extracting matsutake mycelium, using the above-mentioned matsutake mycelium extraction device, including the following steps: opening the cap 22 through the cap opening mechanism, placing the sieve tank 4 containing matsutake mycelium between the upper baffle ring 244 and the lower sealing baffle ring 245, closing the cap 22 and sealing it; controlling the lifting mechanism to lower the sieve tank 4 to the extraction chamber 16, while the upper baffle ring 244 lowers and seals with the horizontal partition 14 to form an extraction chamber, injecting extraction solvent into the extraction chamber 16, controlling the extraction temperature through the jacket 3, and starting the stirring mechanism and the bubbler 11 for dynamic extraction operation; after extraction, opening the extract outlet 12, collecting the extract flowing out of the filter holes of the sieve tank 4 through the extract outlet 12; controlling the lifting mechanism to lower the sieve tank 4 to the extraction chamber 16. Tank 4 is raised to the squeezing and cleaning chamber 15, and at the same time, the lower sealing ring 245 rises and seals with the horizontal partition 14 to form a closed squeezing environment; the squeezing telescopic machine 23 is started to drive the contour squeezing head 231 to physically squeeze the mycelial residue in the sieve tank 4, and the ultrasonic cleaning and extraction mechanism is started to deeply degrease the residue. The recovered high-concentration oil solution is collected separately from the squeezing liquid outlet 141 through the drainage structure on the horizontal partition 14; cleaning liquid is injected into the squeezing and cleaning chamber 15, and the ultrasonic cleaning and extraction mechanism is started to clean the filter holes and surface of the sieve tank 4. At the same time, the cleaning waste liquid is discharged through the squeezing liquid outlet 141; after cleaning, the end cap 22 is opened and the sieve tank 4 is raised to the outside of the reactor body 1 to remove the mycelial residue.

[0036] It is worth noting that the extract obtained through extraction chamber 16 in this application is not the final extracted mycelial oil. Further separation of the extract is required. This solution aims to obtain an extract containing mycelial oil from the mycelial fermentation body. Subsequent separation needs to be achieved by centrifugation equipment, which is a well-known prior art in the field, and therefore will not be traced back.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
