Description

Technical Field

[0001] The invention relates to the technical field of protein extraction, in particular to a device for extracting protein from seabuckthorn seeds. Background Art

[0002] After the oil is extracted from seabuckthorn seeds, they are usually treated as waste, which leads to a waste of resources. In order to make more effective use of these resources, people began to explore ways to reuse seabuckthorn seed waste. Specifically, the seabuckthorn seed waste is first graded through sieves of different specifications, and then goes through 100 mesh, 150 mesh and 200 mesh screening steps. The fine particles after screening are rich in protein and fiber, which become the target of subsequent extraction. After that, these sieves will enter the enzymatic hydrolysis stage. By adding pectinase and cellulase, these enzymes can break down the cell wall and release the encapsulated protein, thereby increasing the protein extraction rate. After the enzymatic hydrolysis is completed, the mixture will be bleached with VC to remove impurities and improve the color of the product. Finally, the bleached liquid is spray-dried at a high temperature of 200°C to convert it into protein powder that is easy to store and transport. This process not only realizes the effective utilization of seabuckthorn seed waste, but also provides a new source of raw materials for food, health products and other fields.

[0003] However, there are some problems with the current equipment used to extract protein from seabuckthorn seed waste. The entire production line consists of multiple independent equipment, including screening equipment, enzymatic reactors, bleaching equipment and spray dryers. These equipment each undertake different processing tasks, but occupy a large area, increasing construction and operating costs. At the same time, due to the lack of tight connection between equipment, materials are easily lost during transfer and processing, affecting the overall extraction efficiency and product quality.

[0004] Therefore, it is necessary to propose a seabuckthorn seed protein extraction device to solve the above problems. Summary of the invention

Therefore, when the second driving source 39 is running, the lifting shaft 11 can be lifted and rotated. Since the lifting shaft 11 is a regular polygonal column, the floating shaft 6 rotates accordingly. , and the floating shaft 6 is connected to the sieve plate 7 for rotation, so the sieve plate 7 will not rotate with it, and the lifting shaft 11 will drive the connecting arm 20 to rotate during the rotation, and the connecting arm 20 drives the driving arm 21 to rotate, and when the lifting shaft 11 descends, the driving arm 21 will be pressed down by the cooperation of the connecting arm 20 and the outer flange 22, and then the driving arm 21 drives multiple sieve plates 7 to move downward through its bottom roller, and then the first spring 19 is compressed, and when the lifting shaft 11 rises, the first spring 19 is reset, and the sieve plate 7 rises, and in this reciprocating manner, the sieve plate 7 continuously moves up and down to achieve screening, and when the floating shaft 6 rotates, it will drive the first arc plate 24 to rotate, and the first arc plate 24 can spread the material accumulated on the top of the sieve plate 7, reducing the possibility of blockage and improving the screening effect, and the lifting shaft 1 During the lifting and lowering, the sealing plug 8 is always located at the inner side of the connecting pipe 4, so that the material will not enter the enzymolysis tank 2. After screening for a certain period of time, the first driving source 15 is controlled to drive the top frame 13, the guide column 14, and the pressure ring 30 to move downward as a whole. The pressure ring 30 will gradually contact the connecting ring 17, and then press the connecting ring 17 downward. The connecting ring 17 also presses down the screen plate 7 through the driving arm 21, and the pressing amplitude is greater than the pressing amplitude when the lifting shaft 11 descends, until the screen plate 7 is pressed down to the lower end of the corresponding slag discharge groove 16, and the top of the screen plate 7 is not lower than the inner bottom wall of the corresponding slag discharge groove 16. At this time, the outer flange 22 moves downward away from the bottom of the connecting arm 20, and due to the downward movement of the screen plate 7, the floating shaft 6 will move downward synchronously. At this time, the sealing plug 8 enters the enzymolysis tank 2 from the connecting pipe 4, Moreover, since the downward movement of the floating shaft 6 will drive the first curved plate 24 to move downward synchronously, the driving rod 28 moves downward relative to the driving groove 29, and the driving groove 29 is displaced to the slope at the lower end of the driving groove 29, and then the driving rod 28 squeezes the second curved plate 25 through the driving block 27, and the second curved plate 25 moves downward and stretches the second spring 26. The bottom of the second curved plate 25 will contact the bottom of the sieve plate 7. Due to the separation of the sealing plug 8 and the connecting pipe 4, the material sieved at the lower end of the screening cylinder 1 will enter the inner side of the enzymolysis tank 2, and then pectinase, cellulase and other necessary materials are added to the enzymolysis tank 2, and then the second driving source 39 is continued to be controlled to operate. Since the outer flange 22 is far away from the bottom of the connecting arm 20, the lifting and lowering of the lifting shaft 11 will not drive the sieve plate 7 to rise and fall, and the sieve plate 7 remains stationary.However, the first curved plate 24 will be driven to rotate. Since the second curved plate 25 and the first curved plate 24 are arc-shaped, and the bottom of the second curved plate 25 is in contact with the top of the sieve plate 7, the second curved plate 25 and the first curved plate 24 will continuously scrape the large particles on the top of the sieve plate 7 from the slag discharge groove 16 when they rotate, and then collect them in the receiving groove 5. The stirring shaft 12 is driven to rotate and lift by the lifting shaft 11, and the stirring blade 45 performs preliminary stirring and mixing. When the material on the sieve plate 7 is discharged, the first driving source 15 drives the guide column 14 and the top The frame 13 and the pressure ring 30 rise as a whole, the first spring 19 is reset, the sieve plate 7 rises to the top of the corresponding slag discharge groove 16, the second arc plate 25 rises and resets, and the sealing plug 8 seals the connecting pipe 4 again, and then the sea buckthorn seed material continues to be added to the screening cylinder 1, and the outer jacket of the enzymolysis tank 2 heats the material inside the enzymolysis tank 2. The lifting shaft 11 continues to screen the material in the screening cylinder 1 during the lifting and rotation, and the stirring shaft 12 is driven to lift and rotate, and the bottom of the inner cavity of the enzymolysis tank 2 is continuously extracted through the piston at the bottom of the stirring shaft 12. The material in the part can be ejected upward through the first release port 43 when the plug rod 48 is moved downward, thereby avoiding deposition. Moreover, since the swivel 46 is rotatably connected to the first plug cylinder 41, the stirring shaft 12 will continuously drive the stirring blade 45 to change its angle when it is lifted and rotated, thereby realizing the change of the path, thereby improving the stirring enzymolysis effect. In addition, when the stirring blade 45 changes its angle, it will continuously drive the plug rod 48 to move through the pin shaft. Since the second plug cylinder 47 can be longitudinally displaced along the stirring shaft 12, the inner peripheral material of the enzymolysis tank 2 can be continuously sucked into the second suction port 49. When the plug rod 48 is displaced in the direction of the stirring shaft 12, the material will be squeezed out from the second release port 50, and then enter the nozzle 44 through the hose, and finally be ejected through the nozzle on the outer circumference of the nozzle 44. The ejected material can flush the inner wall of the enzymolysis tank 2, and can increase the contact opportunity between the material and the outer jacket of the enzymolysis tank 2, thereby improving the enzymolysis effect and efficiency. Finally, it can be discharged through the bottom of the enzymolysis tank 2. Since the inside of the enzymolysis tank 2 needs to be heated, necessary components such as a pressure relief valve can be set on the enzymolysis tank 2. ,
