Description

Technical Field

[0001] The invention relates to the technical field of equipment for preparing antioxidant peptides from pomfret, and in particular to a device and a process for preparing antioxidant peptides from pomfret. Background Art

[0002] Collagen is a fibrous protein widely distributed in the skin, hair, bones and blood vessels of animals. It can support and protect the body. Collagen peptides are a mixture of polypeptides with a molecular weight less than 3kDa produced after enzymatic hydrolysis of collagen. Compared with collagen, it has a better absorption rate; it also has properties that collagen does not have, such as antioxidant, platelet aggregation inhibition and anti-tumor activity. Due to its significant physiological activity, it is currently widely used in various fields such as functional foods, health foods and cosmetics.

[0003] When most fish meat reacts with enzymes, less water is poured into it. When fish meat powder reacts with enzymes, the fish meat cannot react with the enzymes fully and needs to be stirred for a long time to react thoroughly, which causes the reaction time to be longer and the reaction efficiency to be reduced accordingly. Even if there is enough water mixed in the fish meat, some fish meat will still settle at the bottom of the container, affecting the efficiency of the reaction. Summary of the invention

[0018] S4: Expand the stirring area to save reaction time.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention discloses a device for preparing antioxidant peptides using pomfret. The crushed fish meat, enzyme and a certain amount of sterile water are poured into a mixing drum, and then a driving motor is started. The driving motor drives the rotating shaft to rotate, the rotating shaft drives the sleeve to rotate, and the sleeve drives a plurality of trapezoidal stirring racks to rotate simultaneously. Since the inner wall of the mixing drum is provided with a reciprocating thread, the trapezoidal stirring rack will reciprocate up and down under the action of the reciprocating thread during the rotation process. At this time, the fish meat soaked in water will adhere to the water. The trapezoidal stirring rack will move up and down during the rotation process, stirring the fish meat in the water. The centrifugal force generated during the up and down rotation of the trapezoidal stirring rack will lift the fish meat precipitated on the top of the hollow round block, thereby preventing the fish meat precipitate from being unable to fully react with the enzyme.

[0021] (2) The present invention provides a device for preparing antioxidant peptides using silver carp. During the rotation of the rotating shaft, a plurality of centrifugal blades are driven to rotate. The rotation of the centrifugal blades generates a suction force, which draws air into the mixing drum through the ventilation pipe. During the continuous air extraction, a vacuum state is formed in the mixing drum. As the air pressure in the mixing drum decreases, bubbles generated in the mixing drum during the stirring process are broken and eliminated, the liquid volume ratio in the reaction system increases, and the enzyme and crushed fish meat are more evenly distributed in the water, thereby improving the reaction rate. In addition, as the gas in the mixing drum is drained, the corresponding suction force drives the arc sealing plate to move toward the rotating shaft. When the arc sealing plate leaves the arc groove, the outside air enters the centrifugal bellows from the gap between the T-plate and the arc groove, thereby avoiding mechanical damage caused by the continuous air extraction of the centrifugal blades and stabilizing the air pressure in the mixing drum.

[0022] (3) The present invention provides a device for preparing antioxidant peptides using pomfret. During the rotation of the trapezoidal stirring frame, the shaped plate will be driven to rotate, and the shaped plate will drive the limiting rod to rotate. During the rotation, the limiting rod will contact the limiting ring in the annular groove, and the limiting rod will move up and down along the limiting ring. At this time, the limiting spring will undergo a stretching and compression movement, and the limiting rod will drive the tooth plate to move up and down. The tooth plate will drive the two rotating rods to rotate under the action of the two gears, and the rotating rod will drive the stirring roller to rotate. The stirring roller will fully stir the fish meat during the rotation process, thereby further improving the reaction efficiency of the fish meat and the enzyme;

[0023] (4) The present invention provides a device for preparing antioxidant peptides using pomfret. During the rotation of the stirring roller, the limiting rotating plate will drive the limiting rotating plate to rotate. The limiting rotating plate will contact the arc ladder plate. The limiting rotating plate contacting the arc ladder plate will approach the direction of the rotating shaft. The limiting rotating plate drives the two stirring rollers to approach the rotating shaft on the I-shaped rectangular block. At this time, the rotating spring undergoes compression deformation. When the limiting rotating plate leaves the arc ladder plate, the stirring roller will reset under the elastic force of the rotating spring. At this time, the stirring roller will move left and right during the rotation, so that the fish meat and enzyme react more quickly, thereby reducing the time for extracting titanium oxide.

During the continuous air extraction process, a vacuum state will be formed in the mixing drum 1.

[0041] like Figure 1 and Figure 4 As shown, two adaptation mechanisms 6 are arranged on the outer wall of the centrifugal bellows 506, and the adaptation mechanism 6 includes two triangular plates 601 fixedly mounted on the outer wall of the sleeve 503, and a T-plate 602 is slidably mounted on the centrifugal bellows 506, and the right end of the T-plate 602 extends into the centrifugal bellows 506, and two adaptation springs 603 are fixedly mounted on the right inner wall of the T-plate 602, and the right ends of the two adaptation springs 603 are fixedly connected to the centrifugal bellows 506, and an arc-shaped sealing plate 604 is fixedly mounted on the right end of the T-plate 602, and the arc-shaped sealing plate 604 is slidably connected to the arc-shaped groove 509.

[0042] As the gas in the mixing drum 1 is drained, the corresponding suction force will drive the arc-shaped sealing plate 604 to move towards the direction close to the rotating shaft 501. When the arc-shaped sealing plate 604 leaves the arc-shaped groove 509, the outside air will enter the centrifugal air box 506 from the gap between the T-shaped plate 602 and the arc-shaped groove 509, avoiding mechanical damage caused by the continuous suction of the centrifugal fan blade 508 and stabilizing the air pressure in the mixing drum 1 at the same time.

[0043] As Figure 3 shown, a limiting mechanism 7 is arranged in the mixing drum 1. The limiting mechanism 7 includes an annular block 701 fixedly installed on the inner wall of the mixing drum 1.

During the rotation of the limiting rod 705, it will contact the limiting ring 703 in the annular groove 702, and the limiting rod 705 will move up and down along the limiting ring 703.

[0045] As Figure 3 and Figure 6 shown, U-shaped plates 704 are respectively fixedly installed on several trapezoidal stirring frames 504. Limiting rods 705 are respectively slidably installed in several U-shaped plates 704. Several limiting rods 705 respectively penetrate through the U-shaped plates 704.

The bottom ends of several limiting springs 707 are respectively fixedly connected with several U-shaped plates 704. The top ends of several limiting rods 705 all extend into the annular groove 702.

[0046] The limiting spring 707 will undergo stretching and compression movements, and the limiting rod 705 drives the tooth plate 706 to move up and down.

[0047] As Figure 6 shown, a rotating mechanism 8 is respectively arranged on several trapezoidal stirring frames 504. The rotating mechanism 8 includes two rotating rods 801 rotatably installed on the inner wall of the trapezoidal stirring frame 504. Both rotating rods 801 are rotatably connected with the sleeve 503. I-shaped rectangular blocks 802 are respectively fixedly sleeved on two rotating rods 801. Stirring rollers 803 are respectively slidably sleeved on two I-shaped rectangular blocks 802. Rotating springs 804 are respectively sleeved on two I-shaped rectangular blocks 802. One ends of two rotating springs 804 far from the sleeve 503 are respectively fixedly connected with two stirring rollers 803. One ends of two rotating springs 804 close to the sleeve 503 are both fixedly connected with the I-shaped rectangular blocks 802.

[0048] The toothed plate 706 will drive the two rotating rods 801 to rotate under the action of the two gears 805, and the rotating rods 801 will drive the stirring rollers 803 to rotate. The stirring rollers 803 will fully stir the fish meat during the rotation process, further improving the reaction efficiency of the fish meat and the enzyme.

[0049] like Figure 5 and Figure 6 As shown, gears 805 are fixedly sleeved on the two rotating rods 801, and the two gears 805 are meshed with the tooth plate 706. A limiting rotating plate 806 is rotatably sleeved on the two stirring rollers 803. A limiting long groove 807 is provided on the trapezoidal stirring frame 504. The limiting rotating plate 806 passes through the limiting long groove 807 and is slidably connected to the limiting long groove 807. An arc-shaped ladder plate 808 is fixedly installed on the inner wall of the stirring drum 1.

[0050] During the rotation, the stirring roller 803 will drive the limit rotating plate 806 to rotate, and the limit rotating plate 806 will contact the arc ladder plate 808. The limit rotating plate 806 contacting the arc ladder plate 808 will approach the direction of the rotating shaft 501. The limit rotating plate 806 drives the two stirring rollers 803 to approach the direction of the rotating shaft 501 on the I-shaped rectangular block 802. At this time, the rotation spring 804 is compressed and deformed. When the limit rotating plate 806 leaves the arc ladder plate 808, the stirring roller 803 is reset under the elastic force of the rotation spring 804. At this time, the stirring roller 803 will move left and right during the rotation, so that the fish meat and enzyme react more quickly, reducing the time for extracting titanium oxide.

[0051] As shown in the figure, a process of a device for preparing antioxidant peptides using pomfret is shown, and the method steps are as follows:

[0052] S1: Stir up and down to prevent sedimentation;

[0053] S2: Eliminate bubbles and increase reaction rate;

[0054] S3: Stir thoroughly to increase the contact area;

[0055] S4: Expand the stirring area to save reaction time.

[0056] When in use, crushed fish meat, enzyme and a certain amount of sterile water are poured into the mixing drum 1, and then the driving motor 507 is started, the driving motor 507 drives the rotating shaft 501 to rotate, the rotating shaft 501 drives the sleeve 503 to rotate, and the sleeve 503 drives several trapezoidal stirring racks 504 to rotate at the same time. Since the inner wall of the mixing drum 1 is provided with a reciprocating thread, the trapezoidal stirring rack 504 will reciprocate up and down under the action of the reciprocating thread during the rotation process. At this time, the fish meat soaked in the water will be attached to the water, and the trapezoidal stirring rack 504 will stir the fish meat in the water during the up and down movement during the rotation process. The centrifugal force generated during the up and down rotation of the trapezoidal stirring rack 504 will bring up the fish meat precipitated on the top of the hollow circle 3 to prevent the fish meat precipitation from being unable to fully react with the enzyme; during the rotation of the rotating shaft 501, it will drive several centrifugal blades 508 Rotation: The rotation of the centrifugal fan blades 508 will generate a suction force, which will draw air into the mixing drum 1 through the ventilation pipe 505. During the continuous air extraction process, a vacuum state will be formed in the mixing drum 1. Since the air pressure in the mixing drum 1 is reduced, the bubbles generated in the mixing drum 1 during the stirring process will be broken and eliminated, the liquid volume ratio in the reaction system will increase, and the enzyme and the crushed fish meat will be more evenly distributed in the water, thereby improving the reaction rate. In addition, as the gas in the mixing drum 1 is drained, the corresponding suction force will drive the arc-shaped sealing plate 604 to move toward the direction close to the rotating shaft 501. When the arc-shaped sealing plate 604 leaves the arc-shaped groove 509, the outside air will enter the centrifugal bellows 506 from the gap between the T-shaped plate 602 and the arc-shaped groove 509, thereby avoiding mechanical damage caused by the continuous extraction of the centrifugal fan blades 508 and stabilizing the air pressure in the mixing drum 1.

[0057] During the rotation of the trapezoidal stirring frame 504, the U-shaped plate 704 will be driven to rotate. The U-shaped plate 704 will drive the limiting rod 705 to rotate. During the rotation of the limiting rod 705, it will contact the limiting ring 703 in the annular groove 702, and the limiting rod 705 will move up and down along the limiting ring 703. At this time, the limiting spring 707 will undergo stretching and compression movements. The limiting rod 705 drives the toothed plate 706 to move up and down. The toothed plate 706 will drive the two rotating rods 801 to rotate by themselves under the action of the two gears 805. The rotating rod 801 will drive the stirring roller 803 to rotate. The stirring roller 803 will fully stir the fish meat during rotation, further improving the reaction efficiency between the fish meat and the enzyme. During the rotation of the stirring roller 803, it will drive the limiting rotating plate 806 to rotate. The limiting rotating plate 806 will contact the arc-shaped ladder plate 808. The limiting rotating plate 806 that contacts the arc-shaped ladder plate 808 will move closer to the axis 501. The limiting rotating plate 806 drives the two stirring rollers 803 to move closer to the axis 501 on the工字 rectangular block 802. At this time, the rotating spring 804 undergoes compressive deformation. When the limiting rotating plate 806 leaves the arc-shaped ladder plate 808, the stirring roller 803 will reset under the elastic force of the rotating spring 804. At this time, the stirring roller 803 will move left and right during rotation, making the reaction between the fish meat and the enzyme faster and reducing the time for extracting titanium oxide.
