Description

Technical Field

[0001] This utility model relates to the field of soybean protein extraction technology, and in particular to a multi-stage soybean protein extraction device. Background Technology

[0002] Soy protein isolate represents a key product in the modern soybean processing industry. With the continuous advancement of technology and a deeper understanding of the nutritional value and functional characteristics of soy protein, protein isolate has been widely used as a raw material or additive in food processing. It has found applications in meat products, dairy products, frozen foods, confectionery, flour products, and textile industries. In the process of extracting soy protein isolate, soybeans must first be pressed to obtain soybean meal, which is rich in protein.

[0003] However, traditional pressing devices, which only use simple pressing plates, cannot fully release the protein in soybeans, resulting in high protein residue and low extraction efficiency. Existing solutions involve using structures such as grinding discs to finely grind soybeans. For example, an upper and lower grinding disc are set up, with a drive motor driving the lower disc to rotate and work in conjunction with the upper disc to grind the soybeans, thereby improving the degree of protein extraction. However, in actual use, the above devices have the following problems: although the mutual rotation of the upper and lower grinding discs can grind the soybeans, the residual liquid protein inside the material is difficult to extract. At the same time, the material remaining on the surface of the device is difficult to clean, leading to material waste. Therefore, a multi-stage soybean protein extraction device is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A grinding assembly is installed at the bottom of the support frame 4, including a grinding table 3. The grinding table 3 is connected to the top of the extrusion box 1 and fixed to the top of the extrusion box 1. A servo motor 2 5 is fixedly connected to the top of the support frame 4. The output end of the servo motor 2 5 passes through the top of the support frame 4 and is fixedly connected to a grinding disc 6. The servo motor 2 5 provides a good and stable operating platform through the support frame 4. Starting the servo motor 2 5 can drive the grinding disc 6 to rotate. A discharge port 8 is opened at the top of the grinding table 3, and a feed port 7 is opened at the top of the grinding disc 6. The soybeans are initially ground by the grinding disc 6 in conjunction with the grinding table 3. Two inclined plates 1 9 and 2 inclined plates 10 are fixedly connected to the inner side of the extrusion box 1. The inclined plates 1 9 and 2 inclined plates 10 are respectively set at the top and bottom of the inner side of the extrusion box 1, so that the crushed soybeans can fall accurately between the processing equipment. The inner side of the extrusion box 1 is rotatably connected to... Two extrusion rollers 12 are installed in the extrusion box 1 and between inclined plate 9 and inclined plate 2 10. When soybeans slide down from inclined plate 9, they will fall precisely between the extrusion rollers 12 and, driven by the servo motor 3 11, squeeze out the residual protein liquid in the soybeans. The output end of the servo motor 3 11 passes through the right side of the extrusion box 1 and is fixedly connected to the right end of the extrusion rollers 12. Fixed plates 13 are fixedly connected to the front and rear sides of the interior of the extrusion box 1. Two slide rods 14 are slidably connected to the adjacent side of the two fixed plates 13. Scrapers 16 are fixedly connected to the adjacent ends of the slide rods 14. Springs 15 are fixedly connected to the outer walls of the slide rods 14. The scrapers 16 and the fixed plates 13 are connected through the slide rods 14. At the same time, springs 15 are installed between them so that the scrapers 16 and the outer walls of the extrusion rollers 12 can fit together. A cleaning mechanism 2 is provided at the bottom of the extrusion box 1. The cleaning mechanism 2 is used to unclog the pipe blockage.

[0032] Specifically, the grinding table 3 is fixed on top of the extrusion box 1. Through the support frame 4, the servo motor 5 provides a stable operating platform. After starting the servo motor 5, it drives the grinding disc 6 to rotate. The top of the grinding table 3 has a discharge port 8, while the top of the grinding disc 6 has a feed port 7. Soybeans are fed in through the feed port 7 and undergo preliminary grinding by the grinding disc 6 in conjunction with the grinding table 3. The crushed soybeans are then discharged through the discharge port 8 and fall into the extrusion box 1. Inclined plates 9 and 10 are respectively installed at the top and bottom of the inner side of the extrusion box 1 to ensure that the crushed soybeans fall precisely between the processing equipment. Two extrusion rollers 12 are installed in the extrusion box 1 and positioned between the inclined plates 9 and 10. Between 10, when soybeans slide down the inclined plate 9, they will fall precisely between the extrusion rollers 12, and under the drive of the servo motor 11, the residual protein liquid in the soybeans will be squeezed out. The front and rear sides of the extrusion box 1 are fixed with fixing plates 13. The scraper 16 is connected to the fixing plate 13 by the slide rod 14. At the same time, a spring 15 is installed between them, so that the scraper 16 can fit against the outer wall of the extrusion roller 12, so as to scrape off the soybeans adhering to the surface of the extrusion roller 12 and avoid adhesion and blockage. Through the above steps, the residual protein inside can be fully extracted without wasting soybeans. The cleaning mechanism 2 is used to unclog the pipe blockage and ensure the smooth progress of the entire extraction process.

[0033] Reference Figure 1 , Figure 2 and Figure 5The cleaning mechanism 2 includes a valve 201 connected to the bottom of the extrusion chamber 1. A filter tube 202 is connected to the bottom of the valve 201. The filter tube 202 is used to filter and extract protein from soybean residue. To prevent internal residue blockage and ensure proper functioning, the other end of the filter tube 202 is connected to a valve 203. A water inlet 204 is connected to the right end of the outer wall of the filter tube 202. A servo motor 206 is fixedly connected to the bottom of the outer wall of the filter tube 202. The output end of the servo motor 206 passes through the outer wall of the filter tube 202 and is fixedly connected to a rotating rod 205. Two filter plates 209 are fixedly connected to the inner side of the filter tube 202. The filter tube 202 is used for multi-stage filtration. 209 filters and extracts protein from soybean residue. Two cleaning brushes 208 are fixedly connected to the outer wall of the rotating rod 205. Two slag discharge valves 207 are connected to the bottom of the outer wall of the filter tube 202. Two pressure sensors 210 are installed on the top of the outer wall of the filter tube 202. The pressure sensors 210 detect the pressure in the internal area of ​​the filter tube 202. When the internal pressure is too high, it indicates that material blockage has occurred. At this time, the servo motor 206 is started to drive the cleaning brushes 208 on the rotating rod 205 to scrape off the material. The valves 201 and 203 are closed, and water is injected through the water inlet 204. Through reverse flushing, the impurities are discharged through the slag discharge valves 207, improving the cleaning efficiency.

[0034] Specifically, valve 201 is connected to the bottom of the extrusion chamber 1, ensuring the smooth progress of the entire extraction process. Valve 201 is also connected to filter tube 202, which is specifically used for filtering and extracting protein from soybean residue. To prevent internal residue from clogging the filter tube 202 and to ensure the continuity and effectiveness of the filtration process, valve 203 is connected to the other end of the filter tube 202. A water inlet 204 is also connected to the right end of the outer wall of the filter tube 202, allowing water to be injected into the filter tube 202 when necessary to assist in the cleaning process. A servo motor 206 is fixed to the bottom of the outer wall of the filter tube 202. This servo motor 206 is the power core of the entire cleaning mechanism 2. Its output end passes through the outer wall of the filter tube 202 and is fixed with a rotating rod 205. Two cleaning brushes 208 are fixed to the outer wall of the filter tube 202. Driven by a servo motor 206, these two cleaning brushes 208 can effectively remove blockages inside the filter tube 202. Two filter plates 209 are fixedly connected to the inner side of the filter tube 202. These two filter plates 209 use a multi-stage filtration method to finely filter and extract protein from soybean residue. Two slag discharge valves 207 are connected to the bottom of the outer wall of the filter tube 202. These two slag discharge valves 207 play a key role in the cleaning process, as they are responsible for discharging the filtered residue. In order to monitor the pressure status inside the filter tube 202 in real time, two pressure sensors 210 are installed on the top of the outer wall of the filter tube 202. These pressure sensors 210 can accurately detect the pressure inside the filter tube 202.

[0035] Reference Figure 1 and Figure 2 A controller 17 is fixedly connected to the front side of the extrusion box 1. The controller 17 is electrically connected to the servo motor 1 206, the pressure sensor 210, the servo motor 2 5, and the servo motor 3 11 respectively. A bracket 18 is fixedly connected to the bottom of the extrusion box 1. A base 19 is fixedly connected to the bottom end of the bracket 18. A collection box 20 is provided on the top of the base 19. The collection box 20 has a buckle groove 21 on both the front and back sides. A reinforcing plate 23 is fixedly connected to the right side of the bracket 18. The right side of the reinforcing plate 23 is fixedly connected to the bottom of the outer wall of the filter tube 202. Two reinforcing rods 22 are fixedly connected to the inner side of the bracket 18.

[0036] Specifically, the controller 17 is electrically connected to several key components to ensure that the extrusion box 1 can accurately control the extrusion process. In addition, the bottom of the extrusion box 1 is fixed by the bracket 18, and the bottom end of the bracket 18 is connected to the base 19. The top of the base 19 is designed with a collection box 20. This collection box 20 not only facilitates the collection of materials, but also has slots 21 on its front and back sides to facilitate the removal of the collection box 20. In order to further enhance the stability of the structure, a reinforcing plate 23 is fixed to the right side of the bracket 18. The right side of the reinforcing plate 23 is tightly connected to the bottom of the outer wall of the filter tube 202 to ensure the stable installation of the filter tube 202.

[0037] Working principle: First, soybeans are fed in through the feed inlet 7 and are initially ground by the grinding disc 6 and the grinding table 3. The crushed soybeans are discharged through the discharge outlet 8 and fall into the extrusion box 1. When the soybeans slide down the inclined plate 9, they will fall precisely between the extrusion rollers 12. Driven by the servo motor 11, the residual protein liquid in the soybeans is squeezed out. The scraper 16 is in contact with the outer wall of the extrusion roller 12 to scrape off the soybeans adhering to the surface of the extrusion roller 12, so as to avoid the adhesion and blockage and fully extract the residual protein inside.

[0038] Furthermore, the pressure sensor 210 accurately detects the pressure inside the filter tube 202. When excessive internal pressure is detected, it usually indicates that material blockage has occurred. In this case, the system automatically starts the servo motor 206 to drive the cleaning brush 208 on the rotating rod 205 to scrape away the blocked material. At the same time, valves 201 and 203 are closed to prevent material from entering the filter tube 202 further. Subsequently, water is injected into the filter tube 202 through the water inlet 204, and the blocked material is discharged through the slag discharge valve 207 by reverse flushing.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
