[0001] The utility model relates to the technical field of plant protein purification, in particular to a plant protein purification device. Background Art

[0002] Plant protein is a kind of protein, which is derived from plants, has comprehensive nutrition, is similar to animal protein, is easily digested and absorbed by the human body, and has a variety of physiological health care functions. The organic solvent precipitation method is one of the main methods for plant protein purification.

[0003] When the organic solvent precipitation method uses organic solvents such as water-soluble non-ionic polymers to cause protein precipitation, it needs to go through steps such as adding medicine, mixing, reacting, and precipitating. When mixing the medicine and the original plant protein solution, it is often mixed and stirred by a stirring wheel. However, the stirring method of the traditional stirring wheel is relatively single. After stirring in the same direction for a long time, the water flow is in a vortex shape, driving the medicine and the original plant protein solution to flow in the same direction. The efficiency of its mixing and stirring is relatively average. Therefore, there are certain limitations. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a plant protein purification device, which solves the technical problem that when the prior art uses organic solvents such as water-soluble non-ionic polymers to cause protein precipitation, it relies on the natural precipitation method for purification and processing. Without external interference, the reaction efficiency of the original plant protein solution and the medicine in the static state is very slow, and the overall purification process takes a long time, seriously reducing the production efficiency, and further achieving the purpose of improving the production efficiency.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A plant protein purification device includes support frames installed on the left and right sides at the bottom of the purification tank. Inside the purification tank, there is a purification device for quickly purifying the original plant protein solution, and a cleaning device for scraping the plant protein purification residues remaining on the inner wall of the purification tank.

[0006] The purification device includes a rotating shaft located inside the purification tank and extending above its top. A transmission member is arranged on the rotating shaft. A driving motor for driving the rotating shaft to rotate through the transmission member is fixedly installed on the purification tank. Multiple groups of stirring rods are equidistantly arranged on the rotating shaft from top to bottom. A rotating ring is rotatably installed at one end of the stirring rod away from the rotating shaft. Multiple turning plates are installed on the rotating ring and are equally spaced around its outer surface. A medicine injection component for injecting medicine into the purification tank is arranged on the rotating shaft. A turbulence generating component for making the original solution in the purification tank in a disordered flow state when the rotating shaft rotates is arranged at the end of the stirring rod.

[0007] Preferably, the medicine injection assembly includes a medicine injection flow channel opened inside the rotating shaft. A diversion channel communicating with the medicine injection flow channel is opened inside the stirring rod. A medicine injection port communicating with the diversion channel is opened at the end of the stirring rod. A check valve for preventing the backflow of the original plant protein solution is installed in the medicine injection port.

[0008] Preferably, the flow disturbance assembly includes an elastic cord fixedly connected to the end of the stirring rod. The other end of the elastic cord is fixedly connected to a mounting block. A plurality of flow disturbance plates are equidistantly distributed around the outer surface of the mounting block, and the length of one of the flow disturbance plates is greater than that of the other flow disturbance plates.

[0009] Preferably, a torsion spring with both ends fixedly connected to the stirring rod and the mounting block respectively is sleeved on the elastic cord. Cutting and flow disturbance holes for cutting the original plant protein solution are equidistantly penetrated through the turning plate and the flow disturbance plates.

[0010] Preferably, the cleaning device includes connecting rods installed on the upper and lower sides of the outer surface of the rotating shaft. A spring cavity is opened inside the outer end of the connecting rod. A tension spring is fixedly connected to the inner wall of the spring cavity, and an electromagnet is also installed at the center of its inner wall. The electromagnet is located inside the tension spring. The other end of the tension spring is fixedly connected to a sliding rod sliding in the spring cavity. The other end of the sliding rod is fixedly connected to a cleaning scraper for scraping the inner wall of the purification tank.

[0011] Preferably, the sliding rod is made of a magnetic material as a whole, and the cleaning scraper is made of a rubber material as a whole.

[0012] Preferably, a discharge pipe is fixedly connected to the center of the bottom of the purification tank, and an electric sealing valve is installed on the discharge pipe.

[0013] By means of the above technical solution, the present utility model provides a plant protein purification device, which has at least the following beneficial effects:

[0014] 1. When the rotating shaft rotates, the centrifugal force generated injects the medicine into the inside of the original solution, so that the medicine injection is completed while mixing, increasing the contact area between the medicine and the original solution, which is more conducive to the progress of the mixing reaction. And the rotating turning plate realizes the secondary agitation of the original solution, further improving the efficiency of the mixing reaction.

[0015] 2. The centrifugal force generated by the rotation of the stirring rod drives the mounting block to pull the elastic cord outward, so that the flow disturbance plates on its outer surface rotate and impact the original solution. And the length of one of the flow disturbance plates is longer than that of the other flow disturbance plates, causing the overall center of gravity of the mounting block to shift, and then making the flow disturbance plates rotate disorderly in the original solution flow, thereby further disturbing the liquid flow and improving the mixing effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1

[0027] When using organic solvents such as water-soluble non-ionic polymers to precipitate proteins based on the existing prior art, the purification process relies on natural precipitation. Without external interference, the reaction efficiency between the plant protein stock solution and the reagent in the static state is very slow, and the overall purification process takes a long time, seriously reducing the production efficiency. In this embodiment, a plant protein purification device is provided. Please refer to Figures 1 - 5 , this embodiment provides a plant protein purification device, which can accelerate the mixing reaction between the reagent and the plant protein stock solution, thereby improving the overall efficiency of plant protein purification. The plant protein purification device includes support frames 2 installed on the left and right sides at the bottom of the purification tank 1. Inside the purification tank 1, there is a purification device 3 for quickly purifying the plant protein stock solution, and a cleaning device 4 for scraping off the residual plant protein purification substances on the inner wall of the purification tank 1. The plant unit stock solution is introduced into the purification tank 1 through the feeding pipe. Subsequently, the weighed reagent is injected into the plant protein stock solution inside the purification tank 1 through the purification device 3, and it is quickly mixed and stirred to make it react quickly with the reagent, thereby improving the overall purification efficiency of the plant protein. After the purification is completed, the cleaning device 4 is used to scrape off and discharge the residual plant protein purification substances on the inner wall of the purification tank 1 to avoid waste of resources.

[0028] When the prior art uses organic solvents such as water-soluble non-ionic polymers to precipitate proteins, it often relies on natural precipitation for purification and processing. Without external interference, the reaction efficiency between the plant protein stock solution and the reagent in the static state is very slow, and the production efficiency is relatively low. Therefore, a purification device 3 that can accelerate the reaction between the reagent and the plant protein stock solution and thus improve the purification efficiency is proposed. The purification device 3 includes a rotating shaft 303 located inside the purification tank 1 and extending above its top. A transmission member 302 is provided on the rotating shaft 303. A driving motor 301 for driving the rotation of the rotating shaft 303 through the transmission member 302 is fixedly installed on the purification tank 1. A plurality of groups of stirring rods 304 are equidistantly arranged on the rotating shaft 303 from top to bottom. A rotating ring 305 is rotatably installed at one end of the stirring rod 304 away from the rotating shaft 303. A plurality of stirring plates 306 are installed on the rotating ring 305 and are evenly distributed around its outer surface. A medicine injection assembly 307 for injecting the reagent into the purification tank 1 is provided on the rotating shaft 303. A turbulence generating assembly 308 is provided at the end of the stirring rod 304 to make the stock solution in the purification tank 1 flow disorderly when the rotating shaft 303 rotates. After the reagent is injected into the plant protein stock solution, the driving motor 301 is started to drive the rotation of the bevel gear in the transmission member 302, thereby driving the rotation of the driven bevel gear meshed with it, and then driving the rotation of the rotating shaft 303 inside it, so as to drive the rotation of the stirring rod 304 on the outer surface of the rotating shaft 303 to stir and mix the stock solution. At the same time, the stock solution impacts the stirring plate 306, thereby driving the stirring plate 306 to drive the rotating ring 305 to rotate on the stirring rod 304, and further realizing the secondary agitation of the stock solution, and further improving the efficiency of the mixing reaction.

[0029] The conventional medicine injection method often directly pours the reagent into the plant protein stock solution, and this method is not conducive to the rapid mixing of the reagent and the plant protein stock solution. Therefore, a medicine injection assembly 307 for accelerating the mixing of the reagent and the plant protein stock solution is provided. The medicine injection assembly 307 includes a medicine injection flow channel 3071 opened inside the rotating shaft 303. A diversion channel 3072 communicated with the medicine injection flow channel 3071 is opened inside the stirring rod 304. A medicine injection port 3073 communicated with the diversion channel 3072 is opened at the end of the stirring rod 304. A check valve 3074 for preventing the backflow of the plant protein stock solution is installed in the medicine injection port 3073. While stirring the plant protein stock solution, the pre-weighed reagent is poured into the medicine injection flow channel 3071 inside the rotating shaft 303 and spreads into the inside of the diversion channel 3072. The centrifugal force generated by the rotation of the rotating shaft 303 drives the liquid medicine to push open the check valve 3074 and integrate into the inside of the stock solution through the medicine injection port 3073, so as to inject the medicine while mixing, increasing the contact area between the reagent and the stock solution and being more conducive to the progress of the mixing reaction.

[0030] In order to further improve the mixing efficiency of the medicament and the plant protein stock solution, the device is also provided with a flow disturbing component 308. The flow disturbing component 308 includes an elastic cord 3081 fixedly connected to the end of the stirring rod 304. The other end of the elastic cord 3081 is fixedly connected with a mounting block 3082. A plurality of flow disturbing plates 3083 are equidistantly distributed around the outer surface of the mounting block 3082. And the length of one of the flow disturbing plates 3083 is greater than that of the other flow disturbing plates 3083. As the stirring rod 304 rotates, the centrifugal force generated drives the mounting block 3082 to move outward and pull the elastic cord 3081, so that the flow disturbing plates 3083 on the outer surface of the mounting block 3082 rotate and impact the stock solution. And the length of one flow disturbing plate 3083 is longer than that of the other flow disturbing plates 3083, so that the overall center of gravity of the mounting block 3082 is offset, and then the mounting block 3082 and the flow disturbing plates 3083 thereon rotate disorderly in the stock solution flow, thus further disturbing the liquid flow and improving the mixing effect.

[0031] A torsion spring 3084 with both ends fixedly connected to the stirring rod 304 and the mounting block 3082 respectively is sleeved on the elastic cord 3081. Cutting and flow disturbing holes for cutting the plant protein stock solution are equidistantly penetrated through the stirring plates 306 and the flow disturbing plates 308. When the elastic cord 3081 rotates and tightens, it synchronously drives the torsion spring 3084 to twist. When the torsion reaches the limit value of the torsion spring 3084, it drives the mounting block 3082 and the flow disturbing plates 3083 to rotate in the reverse direction, so as to reversely stir the liquid flow in the same direction, further improving the stirring effect. And the cutting and flow disturbing holes opened on the stirring plates 306 and the flow disturbing plates 3083 can better cut and disturb the liquid flow when rotating.

[0032] A discharge pipe is fixedly connected to the center of the bottom of the purification tank 1. An electric sealing valve 5 is installed on the discharge pipe. After the purification is completed, the electric sealing valve 5 can be opened to discharge the plant protein obtained by precipitation after the mixing reaction through the discharge pipe.

[0033] Embodiment 2

[0034] On the basis of Embodiment 1, as Figures 1 - 5As shown, based on the existing problem that after the purification of plant protein, there is residual purified material adhering to the inner wall of the purification tank 1, resulting in waste of resources. Therefore, the device is also provided with a cleaning device 4. The cleaning device 4 includes connecting rods 401 installed on the upper and lower sides of the outer surface of the rotating shaft 303. A spring cavity 402 is formed inside the outer end of the connecting rod 401. A tension spring 403 is fixedly connected to the inner wall of the spring cavity 402, and an electromagnet 404 is also installed at the center of its inner wall. The electromagnet 404 is located inside the tension spring 403. The other end of the tension spring 403 is fixedly connected to a sliding rod 405 that slides inside the spring cavity 402. The other end of the sliding rod 405 is fixedly connected to a cleaning scraper 406 for scraping the residual plant protein purified material on the inner wall of the purification tank 1. The sliding rod 405 is made of a magnetic material as a whole, and the cleaning scraper 406 is made of a rubber material as a whole. After most of the purified material is discharged through the discharge pipe, at this time, the drive motor 301 is started again to drive the rotation of the rotating shaft 303. At the same time, the electromagnet 404 is energized, so that a repulsive force is generated between the electromagnet 404 and the magnetic sliding rod 405, pushing the sliding rod 405 to pull the tension spring 403 and move outward along the inner wall of the spring cavity 402 until the cleaning scraper 406 at its outer end fits against the inner wall of the purification tank 1, so as to scrape off and discharge the residual purified material on the inner wall of the purification tank 1, avoiding waste of resources.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
