Description

Technical Field

[0001] The utility model relates to the technical field of rice bran processing, in particular to a rice bran protein extraction device. Background Art

[0002] Rice bran is mainly made from pericarp, seed coat, endosperm, endosperm and embryo. Therefore, a small amount of rice husk and a certain amount of dust and microorganisms will be mixed in during the processing. Therefore, it can only be used as feed and is the main by-product of rice processing.

[0003] In the prior art, a Chinese patent with a publication number of "CN213791905U" discloses an integrated device for ultrafine grinding of rice bran and protein extraction, wherein a crushing knife is arranged on the outer side of a rotating shaft, and a scraping plate is also arranged on the outer side of the crushing knife to crush the rice bran, and a triangular knife is also arranged on the inner side of the scraping plate, and a grinding disc is also arranged on the lower side of the rotating shaft to better crush the rice bran, thereby solving the problem that most of the existing rice bran grinding and rice bran protein extraction are completed separately, and the two processes are not well connected, resulting in cumbersome processes, thereby increasing the labor intensity of workers and not being very convenient to use.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] Rice bran protein is a protein extracted after rice bran is crushed. In the scheme described above, the rice bran is crushed in advance and then sodium hydroxide solution is added to the crushed rice bran protein to complete the extraction of rice bran protein. However, when the rice bran is crushed, too much rice bran is accumulated on baffle 1 in the tank body, and it can only be discharged to the next process after all the rice bran is crushed. In addition, some rice bran at the bottom cannot be effectively crushed by the crushing knife, which will result in that some rice bran is not crushed very thoroughly. When all of it is discharged into the next process, this will result in that the effect of extracting some rice bran protein is not very good. Utility Model Content

[0032] A stirring assembly is provided inside the grinding chamber 3, and a blowing assembly is provided on the stirring assembly, and the airflow generated by the blowing assembly changes the position of the rice bran inside the grinding chamber 3;

[0034] In this embodiment, the wood bran in the crushing chamber 3 can be crushed by the crushing component, and then the rice bran is filtered by the screen 2. At the same time, the sodium hydroxide solution in the extraction chamber 4 is mixed with the rice bran. At the same time, the second motor 8 in the stirring component drives the stirring blade 10 to rotate through the rotating shaft 9. The stirring blade 10 stirs the sodium hydroxide solution and the rice bran, thereby improving the mixing efficiency of the two, and achieving better results when extracting protein from the rice bran.

[0035] Embodiment 2:

[0036] The blowing assembly is composed of a driving assembly and a diverter assembly. The driving assembly includes a lifting groove 11 and an external thread 12. The lifting groove 11 is arranged inside the inner bottom of the housing 1, and the external thread 12 is arranged outside the rotating shaft 9. The position of the external thread 12 is inside the lifting groove 11. A lifting block 13 is movably mounted on the external thread 12. A crescent pin 14 is arranged on the lifting block 13. The lifting block 13 can reciprocate on the external thread 12 through the action of the crescent pin 14. This technology is well known in the art and will not be described in detail here.

[0037] The lifting block 13 is slidably installed with the lifting groove 11, and a pushing plate 15 is fixedly installed on the side end face of the lifting block 13. An air pump 16 is fixedly installed on the inner top of the lifting groove 11. The air pump is connected with an air intake pipe 21. The air intake pipe 21, the connecting pipe 20 and the exhaust pipe 19 are all provided with a one-way valve. The air intake pipe 21 can allow external gas to enter the air pump 16.

The gas generated by the inflation cylinder 16 will enter the annular tube 18 through the connecting pipe 20. Finally, the gas in the annular tube 18 is discharged into the crushing chamber 3 through multiple exhaust pipes 19. The flow of airflow makes the rice bran in the crushing chamber 3 in a flowing state, so that the crushing blade 7 can better crush the rice bran.

[0040] Working principle:

[0041] When in use, rice bran is put into the crushing chamber 3 in the shell through the feeding pipe 22, and then driven by the first motor 5, the crushing blade 7 is driven to rotate through the rotating shaft 6, and the rice bran on the screen 2 can be crushed by the rotation of the crushing blade 7, and the crushed rice bran will fall into the extraction chamber 4 through the screen 2, and then the sodium hydroxide solution is put into the extraction chamber 4 through the introduction pipe 24. At this time, driven by the second motor 8, the stirring blade 10 is driven to rotate in the extraction chamber 4 through the rotating shaft 9, and the rice bran and the sodium hydroxide solution are stirred and mixed by the stirring blade 10, so as to improve the mixing efficiency of the two, and the effect of protein extraction from the rice bran is better;

[0042] When the second motor 8 drives the stirring blade 10 to rotate through the rotating shaft 9, the rotating shaft 9 will drive the lifting block 13 to move in the lifting groove 11 through the external thread 12. When the lifting block 13 moves, it will drive the piston on the push rod 17 to move in the inflation cylinder 16 through the pushing plate 15. The gas generated by the inflation cylinder 16 will enter the annular tube 18 through the connecting pipe 20. Finally, the gas in the annular tube 18 is discharged into the crushing chamber 3 through multiple exhaust pipes 19. The rice bran in the crushing chamber 3 is in a flowing state through the flow of airflow, so that the crushing blade 7 can better crush the rice bran. At the same time, the lifting block 13 will reciprocate in the lifting groove 11 through the action of the crescent pin 14. The reciprocating lifting of the lifting block 13 keeps the inflation cylinder 16 in a working state, so that the rice bran in the crushing chamber 3 can be better crushed.
