Description

Technical Field

[0001] This invention relates to the field of α-linolenic acid extraction technology from perilla seed oil, specifically to a high-efficiency extraction device and extraction method for α-linolenic acid extraction from perilla seed oil. Background Technology

[0002] Perilla seed oil is obtained from the mature seeds of the medicinal plant Perilla frutescens (Lamiaceae family). It is a highly unsaturated natural oil, with α-linolenic acid as its main component, accounting for approximately 67%. Perilla seed oil is obtained through pressing / leaching, followed by saponification, acidification, washing, dehydration, and molecular distillation to obtain the α-linolenic acid product. However, in the extraction process of perilla seed oil, ordinary extraction equipment cannot guarantee the uniformity of perilla seed drying. This makes it difficult to ensure efficient separation of perilla seeds and perilla seed oil during pressure filtration. After obtaining the perilla seed oil, it still needs to be distilled to obtain α-linolenic acid. However, the uniform heating effect of the perilla seed oil during distillation is poor, resulting in a slow extraction rate of α-linolenic acid. Therefore, we have developed a high-efficiency extraction device and method for the extraction of α-linolenic acid from perilla seed oil. Summary of the Invention

[0003] The purpose of this invention is to provide a high-efficiency extraction device and extraction method for the extraction of α-linolenic acid from perilla seed oil, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency extraction device for extracting α-linolenic acid from perilla seed oil, comprising a base frame, a movable frame mechanism slidably connected to the front upper end of the base frame, a roller mechanism rotatably arranged at the rear upper end of the base frame, a rolling stirring mechanism extending into the roller mechanism fixed at the rear upper end of the movable frame mechanism, and a drying mechanism also installed on the front side inside the base frame.

[0005] The roller mechanism rotates under the drive of the drive mechanism in the base frame. When the roller mechanism rolls, it also drives the moving frame mechanism to move back and forth. When the moving frame mechanism moves back and forth, it delivers the hot air generated by the drying mechanism to the inside of the roller mechanism.

[0006] When the roller mechanism rolls, the rolling and stirring mechanism stirs and rolls the perilla seeds inside the roller mechanism, while the drive mechanism stirs the perilla seed oil inside the base frame.

[0007] Preferably, the base frame includes a base, an arc-shaped groove in the middle of the upper end of the base, and a front receiving cavity and a rear receiving cavity provided at both ends of the arc-shaped groove;

[0008] The base is also provided with an installation groove at the front end, a storage groove at the bottom of the arc-shaped groove, a vertical groove in the middle of the left and right side walls of the storage groove, and support rollers on the front and rear sides of the top of the vertical groove. A motor is installed at the rear end of the base.

[0009] The roller mechanism includes a roller supported on a support roller, a filter screen in the middle of the roller, and annular grooves on the front and rear sides of the filter screen. The annular grooves are provided with annular teeth, and an opening is provided in the middle of the front end of the roller.

[0010] Preferably, the drive mechanism includes a gear mechanism installed inside the front and rear receiving cavities respectively, and a rotating rod arranged left and right in the storage slot;

[0011] The gear mechanism includes a first gear that is movably mounted on the top of the middle section between the front and rear receiving cavities via a rotating shaft, and a second gear that meshes with the left and right sides of the bottom of the first gear.

[0012] The motor shaft at the motor output end extends into the rear receiving cavity and is fixed to the corresponding rotating shaft;

[0013] The front end of the first gear is also fixed with a support rotating disk at the middle of both ends. The top of the first gear extends into the corresponding annular groove and meshes with the bottom of the annular tooth. The support rotating disk is supported on the bottom of the drum.

[0014] The two ends of the rotating rod extend into the front and rear receiving cavities respectively and are fixed to the middle of the corresponding second gear. The rotating rod is also equipped with stirring blades.

[0015] Preferably, the movable frame mechanism includes slide blocks slidably connected to both sides of the upper front end of the base, a cross frame connected to the top of the two sets of slide blocks, a funnel fixed to the top of the cross frame, and a conveying pipe connected to the bottom of the funnel.

[0016] The drying mechanism includes a drying box fixed in the mounting slot, an electric heating wire installed inside the drying box, and a rectangular rubber corrugated pipe connected to the middle of the front end of the drying box.

[0017] A backing plate is also connected between the two sets of slides. The front end of the rectangular rubber corrugated tube is fixed to the rear end of the backing plate, and the two sides of the rear end of the backing plate are fixed to the two sides of the front end of the drying box by tension springs.

[0018] Preferably, the rolling mixing mechanism includes mounting frames fixed on both sides of the rear end of the cross frame, reinforcing plates fixed between the two sets of mounting frames, rolling rollers installed in the middle of the outer side of the mounting frames, and cleaning brushes provided on the outer side walls at both ends of the mounting frames. The rolling rollers and cleaning brushes are in close contact with the inner wall of the roller.

[0019] The front end of the roller is equipped with an end cover mechanism, which includes an end cover fixed to the front end of the roller by countersunk screws and symmetrically arranged arc-shaped protrusions on the end cover. The end cover has an opening in the middle.

[0020] The conveying pipe extends into the drum through the opening and the hole, and the rear ends of the cross frame are movably mounted with abutment wheels via brackets;

[0021] The top of the drying chamber is connected to the bottom front end of the mounting frame via a flexible hose, which communicates with a nozzle on the inner wall of the mounting frame through a channel inside the mounting frame.

[0022] This invention also provides an extraction method for a high-efficiency extraction device for extracting α-linolenic acid from perilla seed oil, specifically including the following steps:

[0023] S1. Put the perilla seeds into the drum mechanism, and then make the drive mechanism drive the drum mechanism to rotate.

[0024] S2. When the drum mechanism rolls, it drives the moving frame mechanism to move back and forth. The moving frame mechanism transports the hot air generated by the drying mechanism to the inside of the drum mechanism to dry and keep the perilla seeds in the drum mechanism warm.

[0025] S3. When the roller mechanism rolls, the rolling and stirring mechanism stirs and rolls the perilla seeds in the roller mechanism. The perilla seed oil produced by rolling falls into the base frame, and the drive mechanism stirs the perilla seed oil in the base frame.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the present invention can realize the rotation of the drum mechanism synchronously through the driving mechanism, the driving mechanism stirs the perilla seed oil, and the moving frame mechanism transports the hot air generated by the drying mechanism to the inside of the drum mechanism when it moves back and forth.

[0027] The reciprocating motion of the cross frame causes the rolling and stirring mechanism to move back and forth in the drum accordingly. This allows the mounting frame and reinforcing plate on the rolling and stirring mechanism to stir the perilla seeds in the drum, which is more conducive to achieving uniform drying of the perilla seeds. In addition, the cleaning brush cleans the inner wall of the drum, which can remove the perilla seeds attached to the inner wall of the drum.

[0028] As the moving frame mechanism moves backward, the abutment plate on the moving frame mechanism presses against the rectangular rubber corrugated tube, causing the rectangular rubber corrugated tube to be compressed. The air inside the rectangular rubber corrugated tube enters the drying chamber, and the air heated by the electric heating wire in the drying chamber is introduced into the nozzle through the hose and the channel inside the mounting frame. Finally, the hot air is introduced into the drum through the nozzle to dry and keep the perilla seeds in the drum warm.

[0029] When the drum rotates, the rolling rollers on the rolling and stirring mechanism roll the perilla seeds, causing them to break and release oil. The obtained perilla seeds enter the storage tank, and the stirring blades on the rotating rod stir the perilla seed oil in the storage tank. This allows the heating rod in the storage tank to heat the perilla seed oil evenly, preparing for the subsequent extraction of α-linolenic acid from the perilla seed oil.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-13 The present invention provides a technical solution:

[0046] Example 1:

[0047] A high-efficiency extraction device for extracting α-linolenic acid from perilla seed oil includes a base frame 1, a movable frame mechanism 4 is slidably connected to the front of the upper end of the base frame 1, a roller mechanism 3 is rotatably arranged at the rear of the upper end of the base frame 1, a rolling stirring mechanism 8 extending into the roller mechanism 3 is fixed at the rear end of the upper part of the movable frame mechanism 4, and a drying mechanism 5 is also installed on the front side inside the base frame 1.

[0048] The upper end of the base frame 1 is also fixed with an arc-shaped protective cover 2 covering the outside of the roller mechanism 3, which prevents the perilla seed oil flowing out through the filter screen 32 from splashing when the roller mechanism 3 rotates.

[0049] The roller mechanism 3 rotates under the drive of the drive mechanism 6 in the base frame 1. When the roller mechanism 3 rolls, it also drives the moving frame mechanism 4 to move back and forth. When the moving frame mechanism 4 moves back and forth, it delivers the hot air generated by the drying mechanism 5 to the inside of the roller mechanism 3.

[0050] When the roller mechanism 3 rolls, the rolling and stirring mechanism 8 stirs and rolls the perilla seeds in the roller mechanism 3, while the driving mechanism 6 stirs the perilla seed oil in the base frame 1.

[0051] The base frame 1 includes a base 101, an arc-shaped groove 105 in the middle of the upper end of the base 101, a front receiving cavity 103 and a rear receiving cavity 106 provided at both ends of the arc-shaped groove 105;

[0052] The base 101 is also provided with an installation groove 102 at the front end, a storage groove 108 at the bottom of the arc groove 105, a vertical groove 109 in the middle of the left and right side walls of the storage groove 108, and support rollers 104 on the front and rear sides of the top of the vertical groove 109. A motor 107 is installed at the rear end of the base 101.

[0053] The front and rear width of the vertical groove 109 is greater than the front and rear length of the filter screen 32. When the drum 31 rotates, the centrifugal force causes a portion of the perilla seed oil flowing out through the filter screen 32 to flow down the arc-shaped protective cover 2 into the vertical groove 109 and then into the storage tank 108 from the vertical groove 109. The other portion of the perilla seed oil flows directly into the storage tank 108 through the filter screen 32, thus allowing the perilla seed oil to be stored in the storage tank 108.

[0054] The roller mechanism 3 includes a roller 31 supported on a support roller 104, a filter screen 32 in the middle of the roller 31, and an annular groove 33 on the front and rear sides of the filter screen 32. The annular groove 33 is provided with annular teeth 35, and the front end of the roller 31 is provided with an opening 34.

[0055] The arc-shaped protective cover 2 covers the outer side of the middle part of the roller 31, and the front and back length of the arc-shaped protective cover 2 is greater than the front and back length of the filter screen 32. When the roller 31 rotates, it prevents the perilla seed oil flowing out through the filter screen 32 from splashing.

[0056] The drive mechanism 6 includes a gear mechanism 61 installed in the front receiving cavity 103 and the rear receiving cavity 106 respectively, and a rotating rod 62 arranged left and right in the storage groove 108.

[0057] The gear mechanism 61 includes a first gear 611 movably mounted on the top of the middle section between the front receiving cavity 103 and the rear receiving cavity 106 via a rotating shaft 613, and a second gear 610 meshing on the left and right sides of the bottom of the first gear 611.

[0058] The motor shaft at the output end of the motor 107 extends into the rear receiving cavity 106 and is fixed to the corresponding rotating shaft 613;

[0059] The front end of the first gear 611 is also fixed with a support rotating disk 612 at the middle of both ends. The top of the first gear 611 extends into the corresponding annular groove 33 and meshes with the bottom of the annular tooth 35. In this way, when the first gear 611 drives the roller 31 to rotate on the support roller 104, it can also prevent the roller 31 from shifting its position back and forth.

[0060] The support rotating disk 612 is supported at the bottom of the roller 31, and in combination with the function of the support rotating disk 612, the active movement of the roller 31 is smoother.

[0061] The two ends of the rotating rod 62 extend into the front receiving cavity 103 and the rear receiving cavity 106 respectively and are fixed to the middle of the corresponding second gear 610. The rotating rod 62 is also provided with stirring blades 63.

[0062] The mobile frame mechanism 4 includes slide blocks 42 that slide on both sides of the upper front end of the base 101, a cross frame 41 connected to the top of the two sets of slide blocks 42, a funnel 45 fixed to the top of the cross frame 41, and a conveying pipe 46 connected to the bottom of the funnel 45.

[0063] When the mobile frame mechanism 4 moves back and forth, the sliding base 42 is slidably connected to both sides of the upper front end of the base 101, which ensures that the mobile frame mechanism 4 moves back and forth smoothly.

[0064] The drying mechanism 5 includes a drying box 51 fixed in the mounting groove 102, an electric heating wire installed inside the drying box 51, and a rectangular rubber corrugated pipe 52 connected to the middle of the front end of the drying box 51.

[0065] The rectangular rubber bellows 52 is also provided with a one-way valve 53 on its side. When the rectangular rubber bellows 52 is compressed, the one-way valve 53 closes, allowing air inside the rectangular rubber bellows 52 to enter the drying chamber 51. When the rectangular rubber bellows 52 expands, the one-way valve 53 closes and opens, allowing outside air to enter the rectangular rubber bellows 52.

[0066] A stop plate 43 is also connected between the two sets of slides 42. The front end of the rectangular rubber corrugated tube 52 is fixed to the rear end of the stop plate 43. The two sides of the rear end of the stop plate 43 are fixed to the two sides of the front end of the drying box 51 by tension springs 44.

[0067] The rolling mixing mechanism 8 includes mounting frames 81 fixed on both sides of the rear end of the cross frame 41, reinforcing plates 84 fixed between the two sets of mounting frames 81, rolling rollers 82 installed in the middle of the outer side of the mounting frame 81, and cleaning brushes 83 provided on the outer side walls at both ends of the mounting frame 81. The rolling rollers 82 and cleaning brushes 83 are in close contact with the inner wall of the roller 31.

[0068] The length of the roller 82 is greater than the front and back length of the filter screen 32. This ensures that the roller 82 always rolls on the filter screen 32 when the moving frame mechanism 4 drives the roller stirring mechanism 8 to move back and forth.

[0069] As the roller 31 rolls over the perilla seeds, some of them break, allowing for further drying of the perilla seeds after hot air enters the roller 31. The perilla seeds continue to be rolled over by the roller 31 until they break and release oil.

[0070] The front end of the roller 31 is equipped with an end cover mechanism 7. The end cover mechanism 7 includes an end cover 71 fixed to the front end of the roller 31 by countersunk screws 72 and arc-shaped protrusions 73 symmetrically arranged on the end cover 71. The end cover 71 has an opening 74 in the middle.

[0071] The conveying pipe 46 extends into the roller 31 through the opening 74 and the opening 34. The rear sides of the cross frame 41 are movably mounted with abutment wheels 47 via brackets 48.

[0072] The abutting wheel 47 abuts against the front end surface of the end cover 71. When the roller 31 drives the end cover 71 to rotate together, the abutting wheel 47 rolls onto the arc-shaped protrusion 73 and then rolls off the arc-shaped protrusion 73.

[0073] The top of the drying oven 51 is connected to the bottom front end of the mounting frame 81 via a flexible hose 54. The flexible hose 54 is connected to a nozzle 85 on the inner wall of the mounting frame 81 via a channel inside the mounting frame 81.

[0074] When the abutment wheel 47 rolls down from the corresponding arc-shaped protrusion 73, the moving frame mechanism 4 moves backward under the tension of the tension spring 44. The abutment plate 43 on the moving frame mechanism 4 squeezes the rectangular rubber bellows 52, causing the rectangular rubber bellows 52 to be compressed. The air inside the rectangular rubber bellows 52 enters the drying chamber 51, and the air heated by the electric heating wire in the drying chamber 51 is introduced into the nozzle 85 through the hose 54 and the channel inside the mounting frame 81. Finally, the hot air is introduced into the drum 31 through the nozzle 85 to dry and keep the perilla seeds in the drum 31 warm.

[0075] This invention also provides an extraction method for a high-efficiency extraction device for extracting α-linolenic acid from perilla seed oil, specifically including the following steps:

[0076] S1. Put the perilla seeds into the roller mechanism 3, and then make the drive mechanism 6 drive the roller mechanism 3 to rotate.

[0077] S2. When the drum mechanism 3 rolls, it drives the moving frame mechanism 4 to move back and forth. The moving frame mechanism 4 moves back and forth to transport the hot air generated by the drying mechanism 5 to the inside of the drum mechanism 3, so as to dry and keep the perilla seeds in the drum mechanism 3 dry.

[0078] S3. When the roller mechanism 3 rolls, the rolling and stirring mechanism 8 stirs and rolls the perilla seeds in the roller mechanism 3. The perilla seed oil produced by rolling falls into the base frame 1, and the drive mechanism 6 stirs the perilla seed oil in the base frame 1.

[0079] Specifically, when using it, put the perilla seeds into the funnel 45. Under the action of gravity, the perilla seeds fall down the conveying pipe 46 into the inside of the roller 31. The mesh of the filter screen 32 is smaller than the diameter of the perilla seeds, so that the perilla seeds will not leak out from the filter screen 32.

[0080] When the motor 107 is working, it drives the first gear 611 at the rear end to rotate through the rotating shaft 613 at the rear end. Then the second gear 610 at the rear end drives the two sets of rotating rods 62 to rotate synchronously in opposite directions. At this time, the stirring blades 63 on the rotating rods 62 stir the perilla seed oil in the storage tank 108.

[0081] The rotation of the rotating rod 62 causes the second gear 610 at the front end to drive the first gear 611 at the front end to rotate, thus making the two sets of first gears 611 at the front and rear ends rotate synchronously.

[0082] Since the top of the first gear 611 extends into the corresponding annular groove 33 and meshes with the bottom of the annular tooth 35, the first gear 611 drives the roller 31 to rotate on the support roller 104.

[0083] When the roller 31 rotates, it drives the end cap 71 at its front end to rotate, so that when the abutment wheel 47 rolls to the middle of the arc-shaped protrusion 73, the abutment wheel 47 pushes the cross frame 41 to move forward against the tension of the tension spring 44 through the bracket 48.

[0084] Then, as the abutment wheel 47 rolls down from the arc-shaped protrusion 73, the crossbeam 41 moves backward under the tension of the tension spring 44.

[0085] With the back-and-forth reciprocating motion of the crossbeam 41, the rolling and stirring mechanism 8 also moves back and forth in the drum 31 accordingly. This allows the mounting frame 81 and reinforcing plate 84 on the rolling and stirring mechanism 8 to stir the perilla seeds in the drum 31, which is more conducive to achieving uniform drying of the perilla seeds. In addition, the cleaning brush 83 cleans the inner wall of the drum 31, which can remove the perilla seeds attached to the inner wall of the drum 31.

[0086] As the moving frame mechanism 4 moves backward, the abutment plate 43 on the moving frame mechanism 4 presses the rectangular rubber corrugated tube 52, causing the rectangular rubber corrugated tube 52 to be compressed. The air inside the rectangular rubber corrugated tube 52 enters the drying chamber 51, and the air heated by the electric heating wire in the drying chamber 51 is introduced into the nozzle 85 through the hose 54 and the channel inside the mounting frame 81. Finally, the hot air is introduced into the drum 31 through the nozzle 85 to dry and keep the perilla seeds in the drum 31 warm.

[0087] When the drum 31 rotates, the rolling roller 82 on the rolling and stirring mechanism 8 rolls the perilla seeds, causing the perilla seeds to break and release oil. The obtained perilla seeds enter the storage tank 108. The stirring blade 63 on the rotating rod 62 stirs the perilla seed oil in the storage tank 108, so that the heating rod in the storage tank 108 can heat the perilla seed oil evenly, in preparation for further extraction of α-linolenic acid from the perilla seed oil.

[0088] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The conveying pipe extends into the drum through the opening and the hole, and the rear ends of the cross frame are movably mounted with abutment wheels via brackets; The top of the drying chamber is connected to the bottom front end of the mounting frame via a flexible hose, which communicates with a nozzle on the inner wall of the mounting frame through a channel inside the mounting frame.

6. An extraction method based on the high-efficiency extraction equipment for α-linolenic acid extraction from perilla seed oil according to any one of claims 1-5, characterized in that: Specifically, the following steps are included: S1. Put the perilla seeds into the drum mechanism, and then make the drive mechanism drive the drum mechanism to rotate. S2. When the drum mechanism rolls, it drives the moving frame mechanism to move back and forth. The moving frame mechanism transports the hot air generated by the drying mechanism to the inside of the drum mechanism to dry and keep the perilla seeds in the drum mechanism warm. S3. When the roller mechanism rolls, the rolling and stirring mechanism stirs and rolls the perilla seeds in the roller mechanism. The perilla seed oil produced by rolling falls into the base frame, and the drive mechanism stirs the perilla seed oil in the base frame.
