Description

Technical Field

[0001] The invention relates to the technical field of coconut protein preparation, and in particular to a separation and purification device for coconut protein. Background Art

[0002] Ultrafiltration is a modern separation technology that has been widely used in industry. After the coconut protein extract is separated by ultrafiltration, the protein macromolecules remain at the inner end of the ultrafiltration tube, while low molecular weight components such as sugar and salt seep to the outer end of the ultrafiltration tube. The coconut protein extract is continuously filtered under a certain pressure, which will concentrate the protein and its combined components. At the same time, the low molecular weight solute solution seeps out at a certain flow rate and gradually separates into protein solution and filtrate, realizing the separation and purification of the extract.

[0003] Before discharging the coconut protein accumulated at the inner end of the ultrafiltration cartridge, it is necessary to stop the feeding system. However, after stopping the feeding, the extract in the ultrafiltration cartridge and its top pipe will be retained due to the loss of pressure, and it is difficult for these retained extracts to actively penetrate the ultrafiltration cartridge to complete separation and purification. At this time, if the cover at the bottom of the ultrafiltration cartridge is directly opened, the retained extract will be discharged along with the coconut protein, reducing the purity of the coconut protein and affecting the effect of separation and purification. To this end, we propose a separation and purification device for coconut protein. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] Example 1

[0034] like Figure 1-Figure 11As shown, a separation and purification device for coconut protein includes a frame 1. Specifically, the frame 1 includes a workbench 12 fixed to a silo 2. A vertical plate 11 fixed to a round shell 31 is symmetrically fixed to the bottom of the workbench 12. A connecting frame is fixed to the inner end of the vertical plate 11. The connecting frame is fixed to the outer end of the round shell 31. A silo 2 is fixed to the frame 1. A visual window is provided on the silo 2 so that the staff can observe the situation inside the silo 2. A separation system 3 is connected and installed at the bottom of the silo 2. An opening and closing mechanism 5 is provided on the separation system 3. A feeding system 6, a power system 4 and a compression mechanism 8 are installed on the silo 2. An exhaust mechanism 7 is provided between the feeding system 6 and the compression mechanism 8. Among them, the extract enters the silo 2 from the feeding system 6, and then the extract enters the separation system 3 under the action of high pressure, the coconut protein macromolecules are intercepted, and the small molecule liquid is discharged through the separation system 3; when the coconut protein in the separation system 3 needs to be taken out, the feeding system 6 stops feeding, and the power system 4 is controlled to first fill the silo 2 with gas. As the air pressure in the silo 2 continues to increase, the extract remaining in the silo 2 can be pressed into the separation system 3 for separation. When the extract in the silo 2 is completely pressed into the separation system 3, the compression mechanism 8 is then controlled to compress the extract remaining in the separation system 3, and the residual extract in the separation system 3 is further separated and purified. This operation can fully separate the residual extract in the separation system 3, ensure the purity of the coconut protein macromolecules discharged subsequently, and the separation and purification effect is better. Then the opening and closing mechanism 5 is controlled to discharge the separated and purified coconut protein.

[0035] The compression mechanism 8 includes a housing 81 fixed to the silo 2, a piston 82 is installed in the housing 81, a moving rod 84 is fixed to the bottom of the piston 82, a blocking plate 85 and a compression plate 86 are fixed to the moving rod 84, and a plurality of tension springs 83 are fixed between the top of the piston 82 and the top wall of the housing 81. The power system 4 includes an air charging pipe 41 connected to the housing 81, a compressor 42 and a solenoid valve 1 41a are installed on the air charging pipe 41, and a branch pipe 43 is connected to the air charging pipe 41, a solenoid valve 2 43a is installed on the branch pipe 43, and the other end of the branch pipe 43 is connected to the silo 2. Wherein, when the coconut protein trapped in the separation system 3 needs to be discharged, the compressor 42 is started first, the gas can be pressed into the inflation pipe 41, the electromagnetic valve 43a is opened, and the gas enters the silo 2 from the branch pipe 43. As the air pressure in the silo 2 continues to increase, the extract remaining in the silo 2 is constantly pressed into the separation system 3 at the bottom of the silo. Under high pressure, these extracts are constantly separated and purified by the separation system 3, until the extract in the silo 2 is completely pressed into the separation system 3. At this time, due to the reason of air pressure balance, the extract remaining in the separation system 3 can not be separated completely. If the coconut protein is directly discharged, these extracts will also be discharged together with the coconut protein, which has a strong impact on the purity of the coconut protein, causing the effect of separation and purification to be affected.

[0036] In order to further separate the extract remaining in the separation system 3, the electromagnetic valve 2 43a is closed and the electromagnetic valve 1 41a is opened, and the gas in the inflation tube 41 is continuously pressed into the housing 81. As the air pressure in the housing 81 continues to increase, the piston 2 82 begins to move downward, and drives the moving rod 84 fixed to the piston 2 82 to move downward, thereby driving the compression plate 86 to move downward. The compression plate 86 extends into the separation system 3 and can compress the extract therein, so that the extract can be separated and purified again, thereby ensuring the purity of the coconut protein discharged subsequently and improving the separation and purification effect;

[0037] The gas in the shell 81 can be released through the exhaust mechanism 7. Under the tension of the tension spring 83, the piston 82 moves upward, driving the moving rod 84 to move upward, which can drive the compression plate 86 and the sealing plate 85 to move back to their original initial state. In the initial state, the sealing plate 85 abuts against the bottom of the shell 81, which can prevent the extraction liquid in the silo 2 from entering the shell 81; the size of the sealing plate 85 is smaller than that of the compression plate 86.

[0038] In this embodiment, the separation system 3 includes a round shell 31 fixed on the frame 1, an outer bracket 32 ​​is fixed in the round shell 31, a separation tube 34 connected to the silo 2 is fixed on the outer bracket 32, a plurality of holes 34a are opened on the separation tube 34, and a filter cartridge 33 is fixed on the outside of the separation tube 34, the filter cartridge 33 is formed by winding a long filter cloth, a drain pipe 35 is connected to the round shell 31, and a discharge pipe 36 is connected to the bottom of the separation tube 34. Among them, the discharge pipe 36 is initially closed, and the discharge pipe 35 is open. The extract enters the separation tube 34. Under high pressure, the extract then passes through the hole 34a and contacts the filter cartridge 33. The coconut protein is trapped in the separation tube 34, and small molecule liquid passes through the filter cartridge 33 and enters the round shell 31. Then, these small molecule liquids are discharged from the discharge pipe 35.

[0039] When the extract in the silo 2 is completely pressed into the separation tube 34 by the high air pressure, the power system 4 continues to introduce gas, and the gas will pass through the channel 34a at the upper part of the separation tube 34 and penetrate the filter cartridge 34 into the round shell 31, and finally the air pressure inside and outside the separation tube 34 will be in a balanced state. Even if the gas is introduced again, the extract remaining in the separation tube 34 cannot pass through the filter cartridge 34 to complete the separation; at this time, the compression plate 86 can be controlled to move downward and extend into the separation tube 34 to squeeze and compress the extract in the separation tube 34. Under the action of pressure, the small molecule liquid in the extract remaining in the separation tube 34 will pass through the filter cartridge 34, and the extract remaining in the separation tube 34 can be separated and purified, thereby improving the effect of separation and purification and ensuring the purity of the coconut protein discharged later.

[0040] In this embodiment, the feeding system 6 includes a feeding pipe 61, a high-pressure feed pump 62 is installed on the feeding pipe 61, and a delivery pipe 63 is installed between the feeding pipe 61 and the silo 2, and a solenoid valve 3 63a is installed on the delivery pipe 63. The high-pressure feed pump 62 is started to pump the extract into the feeding pipe 61, and then the extract can enter the silo 2 from the delivery pipe 63; before starting the power system 4, the solenoid valve 3 63a can be closed in advance.

[0041] Example 2

[0042] refer to Figure 6-Figure 7 , which is basically the same as the embodiment 1, and is more optimized in that the exhaust mechanism 7 includes a cylinder 1 71 connected to the feed pipe 61 and a cylinder 2 76 connected to the housing 81, and both the cylinder 1 71 and the cylinder 2 76 are provided with air holes 78, a piston 1 73 is installed in the cylinder 1 71, a connecting column 74 is fixed on the piston 1 73, and the other end of the connecting column 74 extends into the cylinder 2 76 and is fixed with a sealing plate 77, specifically, the connecting column 74 is slidably installed on the cylinder 1 71 and the cylinder 2 76, and a key slot is provided on the connecting column 74 to prevent the deflection thereof. A spring 75 is sleeved on the connecting column 74, and the spring 75 is fixed between the piston 1 73 and the cylinder 1 71. After the coconut protein is discharged, the feeding system 6 is started and the extracting liquid is pumped in. During this process, the extracting liquid will push the piston 1 73 to move, drive the connecting column 74 fixed to the piston 1 73 to move, and then drive the sealing plate 77 fixed to the connecting column 74 to move. The sealing plate 77 moves and separates from the air hole 78 on the cylinder 2 76. At this time, a large amount of gas filled in the shell 81 is discharged from the air hole 78. As the gas in the upper part of the shell 81 is gradually discharged, the piston 1 73 slowly moves up under the tension of the tension spring 75, driving the moving rod 84 and the blocking plate 75 and the compression plate 86 thereon to move up to the original position;

[0043] When the feeding system 6 stops feeding, under the elastic force of the spring 75, the piston 1 73 moves back, driving the connecting column 75 and the sealing plate 77 thereon to move back until the sealing plate 77 blocks the air hole 78 on the cylinder 2 76; the setting of the exhaust mechanism 7 makes the structure of the device more compact and the linkage is better.

[0044] Furthermore, the exhaust mechanism 7 also includes a stopper 72 symmetrically fixed in the cylinder 1 71 for preventing the spring 75 from being crushed. When the piston 1 73 moves to the maximum distance toward the cylinder 2 76, the stopper 72 will hinder the piston 1 73 from continuing to move, thereby preventing the spring 75 from being damaged due to excessive compression, thereby playing a protective role.

[0045] Example 3

[0046] refer to Figure 9-11, which is basically the same as the embodiment 1, and is more optimized in that the opening and closing mechanism 5 includes a switch part 51 installed in the drain pipe 35 and the discharge pipe 36 and a driving part 52 for controlling the two switch parts 51. The leakage shell 51 of one switch part 511 is fixed in the drain pipe 35, and the leakage shell 511 of the other switch part 51 is fixed in the discharge pipe 36. The switch part 51 includes a leakage shell 511, a round rod 512 is fixed in the leakage shell 511, a slide bar 513 is slidably installed on the round rod 512, a blocking ball 515 is fixed on the top of the slide bar 513, and a sealing ball 514 is fixed on the bottom of the slide bar 513, and the size of the sealing ball 514 is larger than the connection part of the leakage shell 511 to ensure that the sealing ball 514 can completely seal the leakage shell 511. When the sealing ball 514 abuts against the leakage shell 511, sealing can be achieved, and the switch part 51 is in a closed state; when the sealing ball 514 is away from the leakage shell 511, the switch part 51 is in an open state. The driving part 52 includes a rotating shaft 521 rotatably mounted between the liquid discharge pipe 35 and the material discharge pipe 36, and a cam 1 522 and a cam 2 523 are fixed to the two ends of the rotating shaft 521, respectively. The cam 1 522 and the cam 2 523 are arranged in opposite directions, and a gear 1 524 is sleeved and fixed on the rotating shaft 521, and a gear 2 525 is meshed on the gear 1 524. The driving part 52 also includes a motor 526 for driving the gear 2 525 to rotate. In the initial state, the short end of the cam 1 522 abuts against the sealing ball 514 in the liquid discharge pipe 35, and the long end of the cam 2 523 abuts against the sealing ball 514 in the material discharge pipe 36. At this time, the switch part 51 in the liquid discharge pipe 35 is in an open state, and the switch part 51 in the material discharge pipe 36 is in a closed state;

[0047] When the coconut protein in the separation tube 34 needs to be discharged, the motor 526 is started to drive the gear 2 525 to rotate, drive the gear 1 524 to rotate, and then drive the rotating shaft 521 to rotate, and then drive the cam 1 522 and cam 2 523 at both ends of the rotating shaft 521 to rotate 180 °, at this time, the switch portion 51 in the discharge pipe 35 is in a closed state, and the switch portion 51 in the discharge pipe 36 is in an open state, and the coconut protein in the separation pipe 34 can be discharged. The control motor 526 is reversed, so that the cam 1 522 and the cam 2 523 are rotated to the original position, the discharge pipe 35 is in a connected state, and the discharge pipe 36 is in a closed state. At this time, the extract of the next batch can be separated and purified. Through the opening and closing mechanism 5, the two switch portions 51 can be controlled at the same time, and the two switch portions 51 are in different states, which is more convenient to operate.

[0048] Example 4

[0049] refer to Figure 9-10, which is basically the same as the first embodiment, and is more optimized in that the rotating shaft 521 is respectively provided with a pointer 1 9a and a pointer 2 9b at the positions corresponding to the cam 1 522 and the cam 2 523, and one end of the pointer 1 9a and the pointer 2 9b is thicker and the other end is thinner, which is convenient for the staff to distinguish. The staff can judge the state of the two switch parts 51 by the state of the pointer 1 9a and the pointer 2 9b, which is simple and convenient.
