Description

Technical Field

[0001] The invention relates to the field of extraction and separation, and in particular to a three-stage separation and processing device and process for high-gel vegetable protein. Background Art

[0002] In recent years, the demand for high-gelling plant proteins has been growing, especially in the food field. High-gelling plant proteins can enhance the taste, stability and shelf life of products. Among them, plant protein separation technology, as an important protein source, has gradually become the focus of attention in the food, feed and pharmaceutical industries.

[0003] However, the common technical means for separating and extracting high-gel plant protein usually have some problems in daily use. With the advancement of science and technology, technicians in related fields have also optimized the technical means for separating and extracting high-gel plant protein. In order to make a more accurate comparison, a Chinese patent with publication number CN209481523U discloses a plant protein separation and extraction device, including a reaction tank, a filter residue mechanism, a stirring mechanism and an oscillation mechanism. When in use, the filter plate intercepts the debris in the feed slurry, and the grinding disk is used to further squeeze the debris, which is not only conducive to fully extracting the protein in the debris, but also reduces the amount of residue entering the reaction tank, and extends the cleaning cycle of the reaction tank.

[0004] However, when using the above device to separate and extract plant protein, there are still the following problems:

[0005] The above-mentioned device intercepts the debris in the feed slurry through the filter plate and further squeezes the debris with the grinding disk, but the above-mentioned device does not remove the residual filter residue after squeezing out of the reaction tank in time. In the subsequent process of injecting slurry into the reaction tank and filtering through the filter plate, the filter residue previously remaining on the filter plate and the debris after this filtration will accumulate on the filter plate, affecting the effect of subsequent filtration treatment of the liquid slurry. At the same time, the filter residue accumulated on the filter plate will also adhere to a small part of the slurry subsequently added, resulting in a decrease in the subsequent purification quality of the plant protein.

[0006] Therefore, based on the above-stated viewpoint, there is still room for optimization of the existing technical means for separating and extracting plant proteins. Summary of the invention

[0022] Preferably, a driving shaft connected to a stirring frame is passed through the middle of the filter cartridge, and another stirring frame located in the separation chamber is sleeved on the driving shaft.

[0023] In addition, the present invention also provides a three-stage separation and processing process of high-gel vegetable protein, comprising the following steps:

[0024] S1: The plant protein-containing raw liquid is first introduced into the pretreatment chamber and subjected to preliminary solid-liquid separation through the filter screen to separate the floating debris and the liquid. At the same time, the floating debris remaining on the filter screen is further squeezed by the pretreatment device, and the floating debris is driven to separate from the filter screen, thereby achieving the preliminary separation and treatment effect of the plant protein-containing raw liquid.

[0025] S2: The stock solution after preliminary separation enters the separation chamber, and then the vegetable protein in the stock solution is further separated by the separator, while the stirring frame of the separation chamber is driven to rotate to separate the vegetable protein in the separation chamber.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1 To Attachment Figure 8 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses a three-stage separation and processing device and method for high-gel plant protein, which illustrates that the present invention is mainly used in the process of separating and extracting plant protein, and technically realizes the effect of separating and extracting plant protein from a raw liquid containing plant protein; in particular, in the process of separation and extraction, the three-stage separation and processing of plant protein is realized through the mutual cooperation between the pretreatment device, the separator and the extractor, thereby effectively improving the separation and extraction quality of plant protein; and the present invention also drives the ultrasonic generator to reciprocate in the reaction cylinder to realize the effect of promoting the separation and extraction efficiency and effect of plant protein in the separation chamber and the extraction chamber.

[0042] Example 1: Reference Figure 1 and Figure 2As shown, a three-stage separation and processing equipment for high-gel vegetable protein comprises a reactor 1 with a hollow interior, the reactor 1 is connected to external equipment, a vegetable protein-containing stock solution is introduced into the reactor 1 through the external equipment for separation and extraction treatment, a pre-treatment device 2, a separator 3 and an extractor 4 are connected to the reactor 1, during use, the vegetable protein-containing stock solution in the reactor 1 is driven to pass through the pre-treatment device 2, the separator 3 and the extractor 4 in sequence, so as to realize the three-stage separation and extraction processing of the vegetable protein-containing stock solution, and effectively improve the separation and extraction quality of the vegetable protein.

[0043] Reference Figure 2 As shown, the preprocessor 2 includes:

[0044] The filter screen plate 20 is located in the upper part of the reactor 1 and is used for performing preliminary separation treatment on the plant protein-containing raw liquid entering the reactor 1 .

[0045] The separator 3 comprises:

[0046] The partition baffle 30 is connected to the inner wall of the reaction kettle 1 and is located at the lower side of the filter screen plate 20. The partition baffle 30 divides the reaction kettle 1 into a separation chamber and an extraction chamber from top to bottom.

[0047] The filter cartridge 31 is disposed on the partition baffle 30 and is communicated with the separation chamber and the extraction chamber.

[0048] Extractor 4 includes:

[0049] The stirring frame 40 is located in the extraction chamber and is used to accelerate the aggregation and mixing of the desired plant proteins separated in the extraction chamber.

[0050] When in use, the pre-processor 2, the separator 3 and the extractor 4 cooperate with each other to achieve a three-stage separation and processing effect on the plant protein-containing raw liquid, thereby effectively improving the separation and extraction quality of the plant protein.

[0051] Reference Figures 2 to 4 As shown, the reactor 1 includes a pretreatment bin 10 and a reaction barrel 11 which are arranged corresponding to the pretreatment device 2, the separator 3 and the extractor 4. The pretreatment bin 10 includes a temporary storage barrel 100 which is arranged in a horizontal cylindrical shape. The lower side of the temporary storage barrel 100 is connected to a material guide funnel 101 which is arranged to be open upward. The filter screen plate 20 is limitedly connected to the upper side of the material guide funnel 101 to perform preliminary filtering treatment on the plant protein-containing raw liquid entering the temporary storage barrel 100. The temporary storage barrel 100 is connected to an external device to introduce the plant protein-containing raw liquid. The lower end of the material guide funnel 101 is connected to the reaction barrel 11. The filter screen plate 20 is limitedly connected to the pretreatment bin 10. The partition baffle 30, the filter barrel 31 and the stirring frame 40 are limitedly connected in the reaction barrel 11.

[0052] When in use, after the vegetable protein-containing stock solution is introduced into the temporary storage cylinder 100, the floating debris and liquid in the vegetable protein-containing stock solution are initially separated by a filter screen, so as to achieve the effect of initially separating the vegetable protein-containing stock solution.

[0053] Further, refer to Figures 2 to 4 As shown, after the solid-liquid separation is performed through the filter screen plate, the floating debris in the plant protein raw liquid will still remain on the filter screen plate 20, which can easily cause the filter holes on the filter screen plate 20 to be blocked. At the same time, a small amount of raw liquid droplets will remain on the floating debris. Based on this, in order to fully extract the plant protein droplets remaining on the debris and discharge the extracted debris out of the temporary storage tube 100, the preprocessor 2 also includes a driven rotating shaft 21 inserted into the preprocessing bin 10, and the driven rotating shaft 21 is sleeved with an auger blade 22 located in the preprocessing bin 10 and fitted with the inner wall thereof, the length of the auger blade 22 is greater than the length of the filter screen plate 20, and a detachable end cover is connected to the end of the temporary storage tube 100 away from the filter screen plate 20.

[0054] During use, after the initial solid-liquid separation of the raw liquid is carried out through the filter screen 20, the driven rotating shaft 21 and the auger blades 22 are driven to rotate. The rotation of the auger blades 22 pushes the debris retained in the temporary storage tube 100 to rotate and shift, and also drives the debris to slide toward the end cover. In the process of the debris being pushed to slide, due to the pressure and shear force applied by the auger blades 22, the debris is driven to be further squeezed, so that the residual droplets therein are squeezed out and then enter the reaction tube 11, so as to achieve the effect of making full use of the residual droplets on the debris. At the same time, the auger blades 22 not only squeeze the debris, but also push the debris to slide toward the side close to the end cover, so that the debris is away from the filter screen 20, so as to avoid clogging the filter screen 20 and facilitate unified cleaning by the staff.

[0055] It should be noted that the setting height of the filter screen plate 20 should be slightly lower than the inner wall height of the temporary storage tube 100, so that there is still a distance between the filter screen plate 20 and the outer edge of the auger blade 22. At the same time, when the staff injects the plant protein solution into the temporary storage tube 100, they need to inject it away from the end cover side.

[0056] Reference Figure 5 and Figure 6 As shown, the separator 3 is used to further separate the plant protein-containing raw liquid; specifically, the separator 3 also includes an installation cavity formed at the side wall of the reaction tube 11, and a plurality of ultrasonic generators 32 are connected in the installation cavity. The plurality of ultrasonic generators 32 are distributed circumferentially with the axis of the reaction tube 11 as the axis.

[0057] When in use, when ultrasonic waves propagate in the raw liquid containing plant protein in the reaction cylinder 11, high-frequency vibrations will be generated. These vibrations can directly act on plant cells, causing the cell walls to rupture, thereby releasing the proteins in the cells. At the same time, when ultrasonic waves propagate in the raw liquid in the reaction cylinder 11, the micro-gas nuclei in the liquid will vibrate under the action of sound waves and form cavitation bubbles. When the sound pressure reaches a certain value, the cavitation bubbles will grow and suddenly collapse, generating a strong impact force. This impact force helps to destroy the cell walls and further release the protein, thereby achieving a further separation and processing effect on the plant protein.

[0058] Further, refer to Figure 5 and Figure 6 As shown, as the ultrasonic wave propagates through the raw liquid, its sound energy will be absorbed by the medium particles and converted into heat energy, resulting in an increase in the temperature of the medium and plant cell tissues, which helps to increase the solubility of the protein. However, since plant protein molecules are generally sensitive to temperature, the long-term release of ultrasonic waves will cause the temperature of the raw liquid in the reaction cylinder 11 to rise excessively, and the long-term oscillation will cause the denaturation and structural destruction of the plant protein molecules, thereby affecting the quality of the subsequently extracted plant protein. Therefore, a number of controllers 33 are provided in the installation cavity corresponding to the number of ultrasonic generators 32, which are used to control the opening and closing of the ultrasonic generators 32. The controllers 33 and the ultrasonic generators 32 are electrically connected so that the ultrasonic generators 32 are started intermittently to achieve a better separation effect.

[0059] Further, refer to Figure 5 and Figure 6 As shown, a plurality of controllers 33 are symmetrically distributed on both sides of the ultrasonic generator 32. The ultrasonic generator 32 is a variable frequency ultrasonic generator 32. The ultrasonic generator 32 is driven to electrically connect with the two corresponding controllers 33 alternately to control the ultrasonic generator 32 to move upward and electrically connect with the controller 33 on its upper side. The ultrasonic generator 32 will generate a high-frequency wave frequency. Then, after moving downward and electrically connecting with the controller 33 corresponding to its lower side, the ultrasonic generator 32 will generate a low-frequency wave frequency. At the same time, when the ultrasonic generator 32 is in the process of sliding and electrically connecting with the two corresponding controllers 33, the ultrasonic generator 32 stops generating ultrasonic waves.

[0060] Reference Figure 5 and Figure 6As shown, in order to facilitate the sliding of the ultrasonic generator 32, a driven slide plate 34 penetrating the installation cavity is connected to the side of the ultrasonic generator 32 away from the filter cylinder 31, and a driving screw 340 connected to the reaction cylinder 11 is threadedly penetrated on the driven slide plate 34. When in use, by driving the driving screw 340 to rotate, the driven slide plate 34 slides in the vertical direction along the connected driving screw 340 through the thread, and the driven slide plate 34 moves synchronously to drive the connected ultrasonic generator 32 to slide, thereby driving the ultrasonic generator 32 to slide alternately between the two corresponding controllers 33, and realizing the intermittent start and frequency conversion control effect of the ultrasonic generator 32.

[0061] Further, as an optional implementation, refer to Figure 5 and Figure 6 As shown, any two adjacent driven slides 34 are connected together by a connecting arc plate 341, and a driving screw 340 is provided on one of the driven slides 34. After the driven slide 34 is driven to move by rotating the driving screw 340, the driven slide 34 drives the connected ultrasonic generator 32 to slide, and at the same time, the other driven slide 34 is driven to move synchronously through the connected connecting arc plate 341, so as to realize the synchronous sliding of all the driven slides 34, the connecting arc plates 341 and the ultrasonic generator 32.

[0062] It should be noted that since all the ultrasonic generators 32 are driven to slide synchronously and all the ultrasonic generators 32 are arranged circumferentially around the reaction tube 11, in order to avoid interference between the waves emitted by all the ultrasonic generators 32 when they converge in the reaction tube 11, the waves of any two ultrasonic generators 32 are set to different frequencies.

[0063] Reference Figures 5 to 8 As shown, a driving shaft 41 connected to a stirring frame 40 is provided in the middle of the filter cartridge 31, and another stirring frame 40 located in the separation chamber is sleeved on the driving shaft 41. A discharge port (not shown in the figure) located in the extraction chamber is also provided on the reactor 1 to take out the processed plant protein. When in use, by driving the driving shaft 41 to rotate, the driving shaft 41 rotates and drives the two stirring frames 40 connected thereto to rotate and shift with the separation chamber and the extraction chamber respectively, so as to drive the plant protein in the separation chamber and the extraction chamber to accelerate the movement, thereby accelerating the separation of the plant protein in the separation chamber from the plant protein, and accelerating the polymerization of the plant protein in the extraction chamber to form a plant protein with high gel properties.

[0064] In order to facilitate the driving shaft 41, the driven shaft 21 and the driving screw 340 to rotate, so as to form a three-stage separation and processing effect of the plant protein, the driving shaft 41 and the driving screw 340 are connected by a belt drive, and the driving screw 340 extends upward and is connected to the driven shaft 21 by a bevel gear meshing drive. The belt drive and the bevel gear meshing drive are both conventional existing technical means and will not be elaborated here.

[0065] When in use, the driving screw 340 or the active shaft 41 is driven to rotate by the existing motor driving technology, so that the synchronous rotation effect between the driving screw 340 and the active shaft 41 and the driving screw 340 and the driven shaft 21 can be achieved synchronously.

[0066] Based on the above, as the ultrasonic generator 32 slides and connects with the corresponding controllers 33 on its upper and lower sides, it will emit sound waves of different frequencies. At the same time, since the separation of plant protein ions requires overcoming the attraction between molecules, a strong energy input is required during the separation process to cause separation. The aggregation of plant protein ions requires sufficient attraction between molecules, and the ion aggregation requires moderate energy input to avoid excessive dispersion.

[0067] Therefore, in order to further improve the efficiency and effect of extracting and separating plant protein, the two corresponding controllers 33 in the installation cavity are respectively installed in the separation cavity and the extraction cavity. After the ultrasonic generator 32 moves up and is connected to the corresponding controller 33 on its upper side, it will generate a high-frequency band in the separation cavity to promote the efficiency of separating the plant protein in the separation cavity. At the same time, after the ultrasonic generator 32 moves down and is connected to the corresponding controller 33 on the lower side, it will generate a low-frequency band in the extraction cavity to promote the accelerated polymerization of the plant protein in the extraction cavity.

[0068] Example 2: Reference Figures 6 to 8 As shown, on the basis of Example 1, in order to improve the separation and extraction effect of plant protein, the filter cartridge 31 is provided with an external filter membrane structure, which is used to filter the required plant protein into the filter cartridge 31, and at the same time, the active rotating shaft 41 is symmetrically sleeved with an electroplating plate 42 located in the filter cartridge 31, and a plurality of connecting guide rods 43 are commonly connected between the two electroplating plates 42, and the two electroplating plates 42 are respectively connected to external electric wires (not shown in the figure). After power is turned on, an electric field is jointly formed between the two electroplating plates 42, the connecting guide rods 43 and the connected electric wires (not shown in the figure), and the circuit signal enters the extraction chamber downward from the separation chamber.

[0069] When in use, an electric field is formed in the filter cartridge 31. The electric field generally has a certain degree of penetration, which will extend the electric field in the filter cartridge 31 to the outside of the filter cartridge 31, that is, the separation chamber and the extraction chamber. The electric field formed in the filter cartridge 31 affects the movement trajectory of ions outside the filter cartridge 31, and accordingly, the plant protein molecules in the plant protein-containing raw liquid usually have an electric charge and will be affected by the electric field force in the filter cartridge 31, thereby attracting the required plant protein ions to stick to the direction close to the filter cartridge 31, enter the filter cartridge 31 to form a higher purity plant protein-containing permeate, and then enter the extraction chamber, effectively improving the efficiency and effect of separating the plant protein.

[0070] Furthermore, since plant protein molecules with different isoelectric points will exhibit different migration behaviors under different electric field strengths, in order to improve the separation and extraction effect of plant protein, a threaded section 410 located in the filter cartridge 31 is formed on the active rotating shaft 41, and the threaded section 410 is two symmetrically arranged reciprocating threads. The two electroplating plates 42 are respectively driven by the symmetrical and oppositely rotating threads in the two reciprocating threads to slide in opposite or reverse directions. The two electroplating plates 42 are threadedly sleeved on the active rotating shaft 41 and driven by the threaded section 410 to slide axially along the active rotating shaft 41. The two electroplating plates 42 are both connected to the filter cartridge 31 with limited sliding, and the connecting guide rod 43 arranged between the two electroplating plates 42 is a bidirectional telescopic structure.

[0071] When in use, the active rotating shaft 41 is driven to rotate, and the two electroplating plates 42 slide toward or away from each other through the threads of the threaded section 410 on the active rotating shaft 41, so as to adjust the relative position distance between the two electroplating plates 42, thereby achieving control and adjustment of the electric field strength between the two electroplating plates 42 and the connecting guide rod 43, so as to selectively separate and extract plant proteins and effectively improve the purification quality of the target protein.

[0072] It should be noted that the electric field strength between the two electroplating plates 42 is inversely proportional to the distance between the two electroplating plates 42 , that is, when the distance between the two electroplating plates 42 increases, the electric field strength will decrease accordingly, and vice versa.

[0073] At the same time, since the filter cartridge 31 is connected to the separation chamber and the extraction chamber at the same time, in the process of driving the two electroplating plates 42 in the filter cartridge 31 to slide back and forth, the two electroplating plates 42 at this time will continue to slide toward the end of the separation chamber and the bottom of the extraction chamber respectively, so that the plant protein molecules located in the separation chamber will have a traction force to stick to the direction of the filter cartridge 31, and at the same time have a tendency to enter the extraction chamber downward.

[0074] In addition, the present invention also provides a three-stage separation and processing process of high-gel vegetable protein, comprising the following steps:

[0075] S1: The plant protein-containing raw liquid is first introduced into the pretreatment chamber 10, and is subjected to preliminary solid-liquid separation through the filter screen 20 to separate the floating debris and the liquid. At the same time, the floating debris remaining on the filter screen 20 is further squeezed by the pretreatment unit 2, and the floating debris is driven to separate from the filter screen 20, thereby achieving a preliminary separation treatment effect on the plant protein-containing raw liquid.

[0076] S2: The stock solution after preliminary separation enters the separation chamber, and then the vegetable protein in the stock solution is further separated by the separator 3, while the stirring frame 40 of the separation chamber is driven to rotate to separate the vegetable protein in the separation chamber.

[0077] S3: The separated plant protein enters the extraction chamber, and is stirred by the stirring rack 40 in the extraction chamber to promote protein aggregation and mixing, thereby forming plant protein with high gel properties.

[0078] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0079] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

The three-stage separation and processing equipment for high-gel vegetable protein according to claim 1, characterized in that: A driving shaft (41) connected to a stirring frame (40) is provided in the middle of the filter cartridge (31), and another stirring frame (40) located in the separation chamber is sleeved on the driving shaft (41).

10. A three-stage separation and processing process of high-gel vegetable protein, using a three-stage separation and processing equipment of high-gel vegetable protein as claimed in any one of claims 1 to 9, characterized in that: Processing Technology The following steps are involved: S1: The vegetable protein-containing raw liquid is first introduced into a pretreatment chamber (10) and is subjected to preliminary solid-liquid separation through a filter screen (20) to separate floating debris from liquid. At the same time, the floating debris remaining on the filter screen (20) is further squeezed through a pretreatment unit (2) to drive the floating debris away from the filter screen (20), thereby achieving a preliminary separation treatment effect on the vegetable protein-containing raw liquid; S2: the raw liquid after the initial separation enters the separation chamber, and then the vegetable protein in the raw liquid is further separated by the separator (3), and at the same time, the stirring frame (40) of the separation chamber is driven to rotate to promote the separation of the vegetable protein in the separation chamber; S3: The separated plant protein enters the extraction chamber, and is stirred by a stirring rack (40) in the extraction chamber to promote protein aggregation and mixing, thereby forming plant protein with high gel properties.
