Description

Technical Field

[0001] This utility model relates to the field of soybean peptide production technology, specifically to an impurity separator for soybean peptide powder production. Background Technology

[0002] Soybean peptides are peptides obtained from soybean protein through enzymatic hydrolysis. They are mainly oligopeptides composed of 3-6 amino acids, which can quickly replenish the body's nitrogen source, restore physical strength, and relieve fatigue. Soybean peptides have functions such as low antigenicity, cholesterol inhibition, promotion of lipid metabolism, and fermentation. When used in food, they can quickly replenish protein sources, eliminate fatigue, and act as a growth factor for bifidobacteria. Soybean peptides contain a small amount of macromolecular peptides, free amino acids, sugars, and inorganic salts, with a relative molecular mass below 1000. The protein content of soybean peptides is about 85%, and its amino acid composition is the same as that of soybean protein, with a good balance and rich content of essential amino acids.

[0003] However, when producing soybean peptides, an impurity separator is needed to clean the impurities in the soybean peptide powder. However, during the impurity separation process, the soybean peptide powder inside the impurity separator is prone to clogging the separation cylinder, which affects the separation effect of the impurity separator. Therefore, we propose an impurity separator for soybean peptide powder production. Utility Model Content

[0026] Multiple sets of stirring blades 28 are fixedly installed on the outer surface of the rotating rod 23. The stirring blades 28 are located inside the screening and separation cylinder 21 and are in contact with the inner wall of the screening and separation cylinder 21.

[0027] A protective shell 9 is bolted to the outer periphery of the impurity discharge shell 8. The second belt 25, the second driving pulley 24, and the second driven pulley 26 are all located inside the protective shell 9 to provide dust protection for the second belt 25, the second driving pulley 24, and the second driven pulley 26.

[0028] The outer casing 7 is hinged with an inspection door 6, which allows personnel to easily inspect the brush plate 19, air jet pipe 20, and screening and separation cylinder 21 inside the outer casing 7.

[0029] Working principle: After the equipment is started, the drive component works first as the power source, the drive motor 2 runs, and drives the first active pulley 14 at its output end to rotate. The first active pulley 14 drives the rotating rod 23 to rotate synchronously through the tensioned first belt 15, and finally drives the rotating rod 23, which runs through the feed cylinder 5, the outer shell 7, and the impurity discharge shell 8, to rotate as a whole. The staff pours the soybean peptide powder raw material to be separated into the feed hopper 4. The raw material falls naturally into the feed cylinder 5. The spiral feed blades 22 convey the raw material evenly and stably to the screening and separation cylinder 21 inside the outer shell 7 through the spiral propulsion action, so as to avoid the raw material from accumulating and blocking the feed channel. While the rotating rod 23 rotates, the transmission rod 32 is driven to rotate through the second belt 25. The gear 31 at the other end of the transmission rod 32 meshes with the gear ring 33 on the fixed ring plate 34 on the outer surface of the screening and separation cylinder 21, which ultimately drives the screening and separation cylinder 21 to rotate stably in the opposite direction to the rotating rod 23 within the outer shell 7. The part of the rotating rod 23 located inside the screening and separation cylinder 21 is also fixed with multiple sets of stirring blades 28. The stirring blades 28 contact the inner wall of the screening and separation cylinder 21, which both stir the raw materials in the cylinder with the rotating rod, breaking up the raw material agglomerates, and scraping off the powder attached to the inner wall of the cylinder, thus preventing blockage inside the screening and separation cylinder 21. The sieve holes provided in the sieve separation cylinder 21 only allow qualified soybean peptide powder to pass through. Impurities are trapped due to their large particle size. Under the centrifugal force and gravity of the rotating cylinder, the qualified soybean peptide powder passes through the sieve holes and falls into the gap between the outer shell 7 and the sieve separation cylinder 21. Finally, it is discharged through the finished product discharge shell 13 at the bottom of the outer shell 7, becoming the separated "finished peptide powder". Impurities that cannot pass through the sieve holes are gradually pushed to the impurity discharge shell 8 on the right side as the cylinder rotates. Two sets of cleaning brushes 19 are fixed to the inner wall of the outer shell 7. The bristles at the bottom of the brushes are in close contact with the outer surface of the screening and separation cylinder 21. When the screening and separation cylinder 21 rotates, the brushes will continuously brush away the fine powder attached to the outer surface of the cylinder and clear the blocked screen holes. At the same time, the air jet pipe 20 sprays air to the outer surface of the screening and separation cylinder 21 through an external air source to help blow away the fine powder that the brushes cannot clean, ensuring that the screen holes are always unobstructed and maintaining stable screening efficiency, thereby preventing or reducing the blockage of the screening and separation cylinder during the separation of soybean peptide powder impurities. In addition, impurities first enter the return pipe 18 through the impurity discharge shell 8. The impurity discharge pipe 12 on the return pipe 18 is normally in the closed state. Impurities preferentially enter the return cylinder 10 on the back of the frame 1. The return motor 11 on the return cylinder 10 runs, driving the return rod and spiral return blades at its output end to rotate. Through the spiral propulsion, the mixture of "impurities + a small amount of unseparated peptide powder" in the return cylinder 10 is sent back to the feed hopper 4 through the circulation outlet pipe 17 and re-enters the separation process. When the equipment has been running for a period of time and a lot of impurities have accumulated, the return pipe 18 is also equipped with a valve. The operator can open the valve of the impurity discharge pipe 12 and close the valve on the return pipe 18 to directly discharge the pure impurities that cannot be separated, which facilitates the re-separation of the soybean peptide powder that has not been completely separated.
