Description

Technical Field

[0001] The present invention relates to the technical field of pea protein powder detection devices, and more particularly to a device for detecting the emulsification stability of pea protein powder. Background Art

[0002] Pea protein powder is a high-quality protein separated and extracted from peas using advanced technology and low-temperature and low-pressure technology. Pea protein contains eight essential amino acids for the human body and is a complete protein. Emulsion stability refers to the property of the emulsion maintaining a significantly stable state and not producing unstable two-phase stratification. Emulsification is a liquid-liquid interface phenomenon.

[0003] Many foods (such as plant-based beverages, salad dressings, meat substitutes, etc.) require protein powder as an emulsifier to help mix oil and water and maintain a uniform state; if the emulsification stability is poor, the product may have problems such as stratification, precipitation or loose texture, and the functions of pea protein powder produced by different raw materials or processes may vary; in the existing technology, when conducting emulsification stability testing of pea protein powder, most of the time, it is necessary to manually prepare the protein powder-water-oil emulsion, which is labor-intensive and has large errors in manual operation, and the stability and accuracy of the test data cannot be guaranteed.

[0004] In response to the above problems, some solutions have been provided in the prior art. For example, the Chinese utility model patent with authorization announcement number CN211904850U discloses a device for detecting the emulsification stability of pea protein powder. The device automatically configures a pea protein powder-water-oil emulsion for detecting the emulsification stability of pea protein powder, thereby reducing the burden of manual operation and ensuring the uniform mixing of pea protein powder with water and oil, preventing powder agglomeration, and making the material and oil evenly mixed. Although the prior art can make the material and oil evenly mixed, thereby improving the accuracy of the test data, a large amount of protein powder is directly mixed with water in the prior art, which leads to the formation of a large number of powder bubbles wrapped with protein powder between the protein powder and the water, which easily affects the mixing effect between the materials and causes errors in the test data. Summary of the Invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a device for detecting the emulsification stability of pea protein powder, which can achieve the purpose of improving the accuracy of detection data.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] The device for detecting the emulsification stability of pea protein powder comprises a cylinder, a water supply pipe is inserted into the cylinder, and an indirect feeding component is provided on the cylinder;

[0008] The indirect feeding assembly includes a baffle fixedly mounted in the cylinder, and the top wall of the baffle is an inclined surface, a motor is fixedly mounted on the cylinder, a rotating rod is fixedly mounted on the motor, a stirring rod is evenly fixedly mounted on the rotating rod, an annular groove is provided on the baffle, a sealing plate for sealing the annular groove is slidably mounted on the rotating rod, and an elastic pad is jointly installed between the sealing plate and the baffle, a discharge trough is provided on the sealing plate, a first inclined block is fixedly mounted on the bottom wall of the sealing plate, and a first push rod cooperating with the first inclined block is fixedly mounted on the rotating rod, and a refueling assembly is provided on the rotating rod.

[0009] Furthermore, elastic rods are evenly fixedly installed on the baffle and the inner wall of the cylinder, and bumps are evenly fixedly installed on the blocking plate.

[0010] Furthermore, a refueling rod is fixedly mounted on the rotating rod, and a refueling groove is provided on the refueling rod. A refueling pipe is rotatably mounted on the rotating rod, and the refueling pipe is connected to the refueling groove. Refueling holes are evenly provided on the bottom wall of the refueling groove.

[0011] Furthermore, a mounting ring is fixedly installed in the cylinder, and a mixing net is vertically slidably installed in the cylinder, an elastic airbag is installed between the mixing net and the mounting ring, and a second inclined block cooperating with the stirring rod is fixedly installed on the top wall of the mixing net.

[0012] Furthermore, the elastic airbag is provided with an inlet valve whose input end is connected to the cylinder, the mounting ring is provided with a groove, the groove is evenly provided with injection holes, and the elastic airbag is provided with a drain valve whose output end is connected to the groove.

[0013] Furthermore, a slide groove is provided on the cylinder body, a buoyancy plate is slidably installed in the slide groove, and a connecting pipe connected with the output end of the drain valve is fixedly installed on the buoyancy plate.

[0014] Furthermore, two second inclined blocks are symmetrically arranged around the rotating rod.

[0015] Furthermore, the top wall of the blocking plate is an inclined surface.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention sets a blocking plate. When the rotating rod drives the first push rod to rotate, the first push rod drives the blocking plate to move up and down through the first inclined block, and drives the discharge trough to contact the raw material during the upward movement of the blocking plate. At this time, the raw material above the baffle can enter the solution below the cylinder through the discharge trough. When the first push rod is out of contact with the first inclined block, the elastic pad stretches and drives the blocking plate to reset downward. After the blocking plate is reset, it drives the discharge trough to break away from the raw material. The raw material can be intermittently added to the solution in the cylinder, so that the raw material and the solution are quickly and evenly mixed, thereby improving the uniformity of the raw material mixing and playing a role in improving the accuracy of the detection data.

[0018] (2) The present invention provides an elastic rod, which drives the protrusion to move up and down during the up and down movement of the blocking plate. The protrusion will reciprocally hit the elastic rod during the up and down movement, causing the elastic rod to swing back and forth. Then, the raw materials on the top wall of the baffle can be stirred during the back and forth swing of the elastic rod, thereby ensuring that the raw materials move normally into the groove. In addition, when the protrusion hits the elastic rod, the elastic rod transmits the vibration to the baffle, thereby ensuring that the raw materials on the baffle can completely pass through the groove into the cylinder, thereby improving the accuracy of the raw material ratio and further improving the accuracy of the detection data.

[0019] (3) The present invention can block the incompletely mixed raw materials in the solution by setting a mixing net, so that the incompletely mixed raw materials are kept in the middle of the mixed solution, thereby improving the mixing efficiency, thereby preventing the incompletely mixed raw materials from sinking to the bottom, resulting in an excessively high concentration of the solution below, affecting the mixing effect of the solution, and during the rotation of the stirring rod, the second inclined block can drive the mixing net to shake up and down, and then during the shaking of the mixing net up and down, the incompletely mixed raw materials on the top wall of the mixing net can be driven to swing, thereby ensuring uniform mixing of the solution, further improving the accuracy of the detection data;

[0020] (4) The present invention provides grooves, which can drive the solution to be sprayed toward the mixed solution through the injection holes on the grooves during the shaking of the elastic airbag, thereby improving the solution mixing effect. At the same time, the residence time of the oil in the solution below the mixing net is prolonged, and the uniformity of the solution mixing is improved. Under the action of the buoyancy plate, the connecting pipe can always be in contact with the surface solution. Since the oil will float up quickly after entering the solution, the surface solution can be absorbed by setting the buoyancy plate. Then, during the compression of the elastic airbag, the surface solution will be sprayed toward the bottom of the solution through the injection holes, thereby ensuring that the solution is fully and evenly mixed, avoiding uneven solution mixing, which affects the accuracy of the detection data, and further improving the accuracy of the detection data.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 8, a device for detecting the emulsification stability of pea protein powder, comprising a barrel 1, a water supply pipe 2 is inserted into the barrel 1, and an indirect feeding component 3 is provided on the barrel 1;

[0037] The indirect feeding assembly 3 includes a baffle 301 fixedly installed in the cylinder 1, and the top wall of the baffle 301 is an inclined surface, a motor 302 is fixedly installed on the cylinder 1, a rotating rod 303 is fixedly installed on the motor 302, a stirring rod 304 is evenly fixedly installed on the rotating rod 303, an annular groove is provided on the baffle 301, a sealing plate 305 for sealing the annular groove is slidably installed on the rotating rod 303, and an elastic pad 306 is installed between the sealing plate 305 and the baffle 301, a discharge trough 307 is provided on the sealing plate 305, a first inclined block 308 is fixedly installed on the bottom wall of the sealing plate 305, and a first push rod 309 cooperating with the first inclined block 308 is fixedly installed on the rotating rod 303, and a refueling assembly 4 is provided on the rotating rod 303.

[0038] Elastic rods 310 are evenly fixedly mounted on the baffle 301 and the inner wall of the cylinder 1 , and bumps 311 are evenly fixedly mounted on the blocking plate 305 .

[0039] A refueling rod 401 is fixedly mounted on the rotating rod 303 , and a refueling groove 402 is provided on the refueling rod 401 . A refueling pipe 403 is rotatably mounted on the rotating rod 303 , and the refueling pipe 403 is connected to the refueling groove 402 . Refueling holes 404 are evenly provided on the bottom wall of the refueling groove 402 .

[0040] During use, the user can first add a certain amount of aqueous solution into the barrel 1 through the water supply pipe 2, and then start the motor 302 and drive the rotating rod 303 to rotate. During the rotation of the rotating rod 303, the first push rod 309 is driven to rotate. Then, during the rotation of the first push rod 309, it gradually contacts the first inclined block 308 and drives the first inclined block 308 to move upward. During the upward movement of the first inclined block 308, the blocking plate 305 is driven to move upward and squeeze the elastic pad 306. Then, during the upward movement of the blocking plate 305, the discharge chute 307 is driven to contact the raw material. At this time, the raw material above the baffle 301 can pass through The raw material passes through the discharge chute 307 and enters the solution below the cylinder 1. When the first push rod 309 is out of contact with the first inclined block 308, the elastic pad 306 stretches and drives the sealing plate 305 to reset downward. After the sealing plate 305 is reset, it drives the discharge chute 307 to break contact with the raw material. At the same time, the rotating rod 303 drives the stirring rod 304 to stir the mixed solution in the cylinder 1. That is, by setting the sealing plate 305, the raw material can be indirectly added to the solution in the cylinder 1, so that the raw material and the solution can be mixed quickly and evenly, thereby improving the uniformity of the raw material mixing and improving the accuracy of the detection data.

[0041] In the process of the blocking plate 305 moving up and down, the protrusion 311 is driven to move up and down, and in the process of the protrusion 311 moving up and down, it will reciprocally hit the elastic rod 310, and make the elastic rod 310 swing back and forth, and then in the process of the elastic rod 310 swinging back and forth, the raw materials on the top wall of the baffle 301 can be stirred, thereby ensuring that the raw materials move normally into the groove 602, and in the process of the protrusion 311 hitting the elastic rod 310, the elastic rod 310 transmits the vibration to the baffle 301, thereby ensuring that the raw materials on the baffle 301 can completely pass through the groove 602 into the cylinder 1, thereby improving the accuracy of the raw material ratio and further improving the accuracy of the detection data.

[0042] During the rotation of the rotating rod 303, the refueling rod 401 is driven to rotate. At the same time, the user can add oil to the refueling tank 402 through the refueling pipe 403, and then the oil flows evenly into the mixed solution through the refueling hole 404 on the refueling tank 402. Since the density of the oil is relatively small, it will float upward in the solution. By adding the oil evenly to the bottom of the mixed solution, the oil can be fully contacted with the mixed solution, thereby further improving the uniformity of the mixing between the oil, raw materials and water, and further improving the accuracy of the detection data.

[0043] A mounting ring 501 is fixedly installed in the cylinder 1, and a mixing net 502 is vertically slidably installed in the cylinder 1. An elastic airbag 503 is installed between the mixing net 502 and the mounting ring 501. A second inclined block 504 that cooperates with the stirring rod 304 is fixedly installed on the top wall of the mixing net 502.

[0044] The elastic airbag 503 is provided with an inlet valve 601 whose input end is connected to the cylinder 1 , the mounting ring 501 is provided with a groove 602 , the groove 602 is evenly provided with injection holes 603 , and the elastic airbag 503 is provided with a drain valve 604 whose output end is connected to the groove 602 .

[0045] The cylinder 1 is provided with a slide groove 606 , in which a buoyancy plate 605 is slidably mounted. A connecting pipe 607 connected to the output end of the drain valve 604 is fixedly mounted on the buoyancy plate 605 .

[0046] By adopting the above technical solution, in the process of the rotating rod 303 driving the stirring rod 304 to stir the mixed solution in the cylinder 1, the mixing net 502 can be provided to block the incompletely mixed raw materials in the solution, so that the incompletely mixed raw materials are kept in the middle of the mixed solution, thereby improving the mixing efficiency, thereby preventing the incompletely mixed raw materials from sinking to the bottom, resulting in an excessively high concentration of the solution below, and affecting the mixing effect of the solution. At the same time, in the process of rotation, the stirring rod 304 gradually contacts the inclined surface of the second inclined block 504 and drives the second inclined block 504 to move downward. In the process of the second inclined block 504 moving downward, the mixing net 502 is driven to move downward and squeeze the elastic airbag 503. Then, when the second inclined block 504 is out of contact with the stirring rod 304, the elastic airbag 503 extends and drives the mixing net 502 to return to its original position upward. That is, in the process of the stirring rod 304 stirring and mixing the mixed solution, it can also drive the mixing net 502 to swing up and down. Then, in the process of the mixing net 502 swinging up and down, it can drive the incompletely mixed raw materials on the mixing net 502 to swing, thereby ensuring uniform mixing of the solution and further improving the accuracy of the detection data.

[0047] During the extension of the elastic airbag 503, the solution is sucked in through the liquid inlet valve 601. Then, during the compression of the elastic airbag 503, the solution in the elastic airbag 503 flows into the groove 602 through the liquid discharge valve 604 and is sprayed toward the mixed solution through the injection hole 603 on the groove 602. This improves the solution mixing effect while extending the residence time of the oil in the solution below the mixing net 502, further improving the uniformity of the solution mixing and thus further improving the accuracy of the detection data.

[0048] During the extension of the elastic airbag 503, the elastic airbag 503 absorbs the solution through the liquid inlet valve 601 and the connecting tube 607, and under the action of the buoyancy plate 605, the connecting tube 607 can always be in contact with the surface solution. Since the oil will float up quickly after entering the solution, the surface solution can be absorbed by setting the buoyancy plate 605, and then the surface solution will be sprayed to the bottom of the solution through the injection hole 603 during the compression of the elastic airbag 503, thereby ensuring that the solution is fully and evenly mixed, avoiding uneven mixing of the solution, affecting the accuracy of the detection data, and further improving the accuracy of the detection data.

[0049] Two second inclined blocks 504 are symmetrically arranged around the rotating rod 303 .

[0050] By adopting the above technical solution, in the process of the second inclined block 504 driving the mixing net 502 to move, the two symmetrically arranged second inclined blocks 504 can make the mixing net 502 evenly stressed, avoiding the mixing net 502 from being stuck due to uneven stress, thereby ensuring the normal movement of the mixing net 502.

[0051] The top wall of the blocking plate 305 is an inclined surface.

[0052] By adopting the above technical solution and making the top wall of the blocking plate 305 an inclined surface, it is possible to avoid residual raw materials on the top wall of the blocking plate 305, which would cause the ratio of the mixed solution to change and affect the accuracy of the detection data.

[0053] Working principle: The user can first add a certain amount of aqueous solution into the cylinder 1 through the water supply pipe 2, then start the motor 302 and drive the rotating rod 303 to rotate, and in the process of the rotating rod 303 rotating, drive the first push rod 309 to rotate, and then in the process of the first push rod 309 rotating, gradually contact with the first inclined block 308 and drive the first inclined block 308 to move upward, and in the process of the first inclined block 308 moving upward, drive the blocking plate 305 to move upward and squeeze the elastic pad 306, and then in the process of the blocking plate 305 moving upward, drive the discharge chute 307 to contact with the raw material, at this time, the raw material above the baffle 301 can enter the solution below the cylinder 1 through the discharge chute 307, when the first push rod 309 contacts the first inclined block 30 After the sealing plate 305 is disengaged, the elastic pad 306 stretches and drives the blocking plate 305 to reset downwards. After the blocking plate 305 is reset, the discharging chute 307 is disengaged from the raw material. At the same time, the rotating rod 303 drives the stirring rod 304 to stir the mixed solution in the cylinder 1. In the process of the blocking plate 305 moving up and down, the protrusion 311 is driven to move up and down, and in the process of the protrusion 311 moving up and down, it will reciprocally hit the elastic rod 310 and make the elastic rod 310 swing back and forth. Then, in the process of the elastic rod 310 swinging back and forth, the raw material on the top wall of the baffle 301 can be stirred, thereby ensuring that the raw material moves normally into the groove 602, and in the process of the protrusion 311 hitting the elastic rod 310, the elastic rod 310 The vibration is transmitted to the baffle 301, thereby ensuring that the raw materials on the baffle 301 can completely enter the cylinder 1 through the groove 602; the refueling rod 401 is driven to rotate during the rotation of the rotating rod 303. At the same time, the user can add oil to the refueling tank 402 through the refueling pipe 403, and then the oil flows evenly into the mixed solution through the refueling hole 404 on the refueling tank 402. Since the density of the oil is relatively small, it will float upward in the solution. By evenly adding the oil to the bottom of the mixed solution, the oil can be fully contacted with the mixed solution. In the process of the rotating rod 303 driving the stirring rod 304 to stir the mixed solution in the cylinder 1, the mixing net 502 can be provided to block the raw materials that are not completely mixed in the solution. The stirring rod 304 is blocked, so that the raw materials that are not completely mixed are kept in the middle of the mixed solution, thereby improving the mixing efficiency. During the rotation of the stirring rod 304, it gradually contacts the inclined surface of the second inclined block 504 and drives the second inclined block 504 to move downward. During the downward movement of the second inclined block 504, it drives the mixing net 502 to move downward and squeezes the elastic airbag 503. Then, when the second inclined block 504 is out of contact with the stirring rod 304, the elastic airbag 503 stretches and drives the mixing net 502 to return to its original position upward. That is, during the process of the stirring rod 304 stirring and mixing the mixed solution, it can also drive the mixing net 502 to swing up and down. Then, during the up and down swinging of the mixing net 502, the raw materials that are not completely mixed on the mixing net 502 can be driven to swing.During the expansion of the elastic airbag 503, the solution is drawn in through the liquid inlet valve 601. Then, during the compression of the elastic airbag 503, the solution in the elastic airbag 503 flows into the groove 602 through the liquid discharge valve 604 and is sprayed toward the mixed solution through the spray holes 603 in the groove 602, thereby improving the mixing effect of the solution and extending the residence time of the oil in the solution below the mixing net 502. During the expansion of the elastic airbag 503, the elastic airbag 503 draws in the solution through the liquid inlet valve 601 and the connecting pipe 607. The buoyancy plate 605 ensures that the connecting pipe 607 is always in contact with the surface solution. Since the oil will float up quickly after entering the solution, the buoyancy plate 605 can draw in the surface solution. Then, during the compression of the elastic airbag 503, the surface solution is sprayed toward the bottom of the solution through the spray holes 603, thereby ensuring that the solutions are fully and evenly mixed.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
