Description

[0002] Spirulina is a microalgae rich in a variety of active substances, which have wide application value in the fields of food, health products, medicine, etc. In order to effectively extract the active substances in spirulina, it is usually necessary to dry the spirulina first to remove the moisture in it, then break it into small particles, and finally obtain the required pure active substances through solvent extraction, separation and purification.

[0003] However, in actual operation, due to the certain volume and hardness of spirulina, it is often difficult to obtain an ideal grinding effect when spirulina is directly placed in a crushing device for crushing. The crushing uniformity is poor and large particles are prone to exist. The active substances in these particles are difficult to be fully released, thus affecting the extraction efficiency. In addition, due to the unsatisfactory crushing effect, it often takes a long time to achieve the required powder fineness, which not only increases production costs, but also reduces production efficiency.

[0060] The present application also includes an embodiment, specifically a method for extracting active substances from Spirulina, which uses the above-mentioned device for extracting active substances from Spirulina to perform extraction, comprising the following steps:

[0061] Step 1: placing the dried spirulina in a pretreatment mechanism for pre-crushing, and further grinding through a grinding and filtering mechanism below the pretreatment mechanism;

[0062] Step 2: When the feeding mechanism starts to rise, the air blowing mechanism blows the ground powder to the periphery of the grinding and filtering mechanism for filtering, and the qualified powder falls down, and then the pre-treatment mechanism discharges part of the pre-crushed spirulina;

[0063] Step 3: After the material is discharged, the falling spirulina and the unqualified powder after filtering can be pushed to the middle of the grinding and filtering mechanism to wait for grinding according to the continuous rise of the feeding mechanism;

[0064] Step 4: The unloading mechanism descends and resets, the pretreatment mechanism continues pre-crushing, and the grinding and filtering mechanism continues to further grind into powder;

[0065] Step 5: The ground spirulina powder can be used to extract active substances by solvent extraction. Commonly used solvents include water, ethanol, acetone, etc. The specific selection depends on the properties of the active substances to be extracted. Using existing technical means, solvent extraction can be carried out by leaching, reflux extraction, Soxhlet extraction, etc. to improve the extraction efficiency;

[0066] Step 6: The mixture after extraction contains the active substances of Spirulina and other impurities. The active substances need to be separated from the mixture by centrifugation, filtration, chromatography (such as gel chromatography, ion exchange chromatography, affinity chromatography, etc.) and purified. This step can also adopt existing technical means and will not be described in detail.

[0067] Step 7: The extracted and purified active substances usually need to be dried to remove moisture and improve their stability. The dried active substances can be stored under appropriate conditions such as low temperature, light protection, and sealing for subsequent use.

[0068] The working principle of a spirulina active substance extraction device is that the dried spirulina is pre-crushed in a pre-treatment housing 3 and further ground into powder between a first grinding disc 21 and a second grinding disc 22 during use;

[0069] Specifically, the first driving source 4 is controlled to drive the second rotating shaft 41, the anti-rotation column 20, the first rotating shaft 17, and the first grinding disc 21 to rotate as a whole, and the second rotating shaft 41 drives the crushing knife 42 to rotate for pre-crushing. At the beginning, the pre-treated material has not fallen yet. At this time, although the first grinding disc 21 rotates, it does not play a grinding role. After grinding, the second driving source 9 drives the first rotating shaft 17, the anti-rotation column 20, the first grinding disc 21, and the lifting cylinder 16 to move upward as a whole. Under the action of the plug plate 39, a positive pressure is generated inside the lower end of the lifting cylinder 16, and the gas enters the conical groove 30 through the outlet pipe 29. Through the guiding effect of the guide cone 23, the air flow blows to the top of the second grinding disc 22. Since there is no material on the top of the second grinding disc 22 at this time, the air blowing does not work. , and in the early stage of the lifting cylinder 16 rising, the guide wheel 43 moves up in the second guide groove 44, and the scraper plate 8 and the driving plate 11 remain stationary. As the lifting cylinder 16 moves up, the first through hole 19 gradually corresponds to the second through hole 40, and the pre-crushed spirulina in the pre-treatment shell 3 falls to the periphery of the filter plate 12, and due to the effect of the guide seat 13, the spirulina will exist in the area between adjacent guide seats 13, and then the first through hole 19 rises to above the second through hole 40, the second through hole 40 is closed, and the guide wheel 43 enters the third guide groove 45, and then the driving plate 11 drives the scraper plate 8 to move to the middle, and the scraper plate 8 pushes the spirulina particles that have just fallen from the periphery of the filter plate 12 to between the first grinding disk 21 and the second grinding disk 22, and the spirulina material enters the first grinding disk After the first grinding disc 21 and the second grinding disc 22 are moved between, the second driving source 9 is controlled to drive the first rotating shaft 17, the first grinding disc 21 and the lifting cylinder 16 to move downward and reset as a whole, and the driving plate 11 drives the scraper plate 8 to move outward and reset. After resetting, the second driving source 9 is turned off, and the first driving source 4 is started again. Then the second rotating shaft 41, the anti-rotation column 20, the first rotating shaft 17 and the first grinding disc 21 rotate as a whole again, and the pre-treatment shell 3 is pre-crushed. The first grinding disc 21 and the second grinding disc 22 are ground, and during the crushing and grinding, the rotating drum 15 will rotate with the first rotating shaft 17 under the action of the first guide groove 24 and the guide block 28, and when the rotating drum 15 drives the driving rod 18 to rotate, the driving rod 18 will push the driving sheet 33, and then the driving sheet 33 drives the flip plate 25 to flip The first torsion spring 35 is twisted, and the knocking head 31 is separated from the bottom of the filter plate 12. When the driving rod 18 is separated from the driving sheet 33, the first torsion spring 35 is reset, and then the flip plate 25 drives the knocking head 31 to knock on the bottom of the filter plate 12. The powder ground to the periphery of the filter plate 12 can be screened under the knocking. After grinding, the first driving source 4 stops, and the second driving source 9 drives the first rotating shaft 17, the anti-rotation column 20, the first grinding disk 21, and the lifting cylinder 16 to move upward as a whole. Under the action of the plug plate 39, a positive pressure is generated inside the lower end of the lifting cylinder 16, and the gas enters the conical groove 30 through the outlet pipe 29. Through the guiding effect of the guide cone 23, the airflow takes effect at this time, and the airflow blows the residual powder on the top of the second grinding disk 22 to the periphery of the filter plate 12 for filtration.Since the guide wheel 43 moves upward in the second guide groove 44 in the early stage of the lifting cylinder 16 rising, the scraper plate 8 and the driving plate 11 remain stationary. As the lifting cylinder 16 moves upward, the first through hole 19 gradually corresponds to the second through hole 40, and the pre-crushed spirulina in the pre-treatment shell 3 continues to fall to the periphery of the filter plate 12. Due to the effect of the guide seat 13, the spirulina will exist in the area between the adjacent guide seats 13. Then, the first through hole 19 rises to above the second through hole 40, the second through hole 40 is closed, and the guide wheel 43 enters the third guide groove 44. The driving plate 11 drives the scraper plate 8 to move toward the middle, and the scraper plate 8 pushes the spirulina particles just dropped from the periphery of the filter plate 12 and the unqualified spirulina after grinding and filtration to between the first grinding disc 21 and the second grinding disc 22. When the first rotating shaft 17 rises, the rotation of the drum 15 is also realized. Specifically, when the first rotating shaft 17 rises, the guide block 28 is driven to rise. The guide block 28 realizes the rotation of the drum 15 through the first guide groove 24. The drum 15 drives the driving rod 18 to rotate, and the driving rod 18 drives the flip plate 25 flips and knocks the bottom of the filter plate 12, so that the fallen spirulina and the spirulina blown to the periphery of the filter plate 12 are screened. After the spirulina material is replenished, the second driving source 9 drives the first rotating shaft 17, the first grinding disc 21, and the lifting cylinder 16 to move downward and reset as a whole, and the driving plate 11 drives the scraper plate 8 to move outward and reset, and the second driving source 9 can control the distance between the first grinding disc 21 and the second grinding disc 22, so as to adjust the grinding effect. After resetting, the second driving source 9 is turned off, and the first driving source 4 is started again. Then the second rotating shaft 41, the anti-rotation column 20, the first rotating shaft 17, and the first grinding disc 21 rotate as a whole again, and the pre-treatment shell 3 is pre-crushed, and the first grinding disc 21 and the second grinding disc 22 are further ground into powder. The knocking mechanism at the bottom of the filter plate 12 continues to knock and screen the spirulina particles on the periphery of the filter plate 12, and the qualified spirulina powder falls into the receiving tank body 10 for collection, and this cycle is repeated. Finally, the material taking door 2 can be opened to take out the receiving tank body 10 for subsequent solvent extraction and separation and purification steps;

[0070] It should be noted that when the first rotating shaft 17 drives the guide block 28 to move downward, the rotating drum 15 is reversed, during which the driving rod 18 will push the driving plate 33 in the opposite direction from the side close to the stop block 32, and then the driving plate 33 will flip, and the second torsion spring 37 will twist. During this period, the flip plate 25 will not flip and drive the knocking head 31 to knock on the bottom of the filter plate 12;

[0071] When the lifting cylinder 16 moves downward, negative pressure is generated at the bottom of the plug plate 39, and external gas enters the inner cavity at the lower end of the lifting cylinder 16 through the air inlet pipe 38.

[0072] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above.

[0073] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and improvements, and these changes and improvements shall all fall within the scope of the present invention claimed for protection.
