Description

Technical Field

[0001] This application relates to the technical field of soybean flour grinding equipment, specifically a high-efficiency grinding device for soybean protein powder. Background Technology

[0002] In the food processing industry, soybean flour, as an important raw material rich in plant protein, dietary fiber, and various nutrients, is widely used in the production of various foods such as baked goods, beverages, and snack foods due to its good water solubility and functionality. The grinding quality of soybean flour (such as particle size uniformity and cell wall breakage rate) and grinding efficiency not only directly affect the taste, texture, and other quality characteristics of the final food products, but also relate to the production line's capacity output and production cost control.

[0003] In some existing high-efficiency soybean flour grinding devices, soybean flour easily remains on the surface of the grinding roller during actual use. If it is not cleaned in time, the accumulation of residual soybean flour will not only affect the rotation accuracy and grinding force of the grinding roller, resulting in uneven particle size and reduced grinding efficiency, but also may cause mold, rancidity and other deterioration due to long-term contact with humid air or high temperature environment, thus contaminating the soybean flour raw materials to be ground later and affecting the food safety of the product. Therefore, it is necessary to design a high-efficiency soybean protein powder grinding device to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a high-efficiency soybean protein powder grinding device, which solves the problem that some existing high-efficiency soybean powder grinding devices suffer from reduced grinding efficiency, uneven particle size, and food safety issues caused by soybean powder residue on the surface of the grinding rollers not being cleaned in time.

[0006] The technical solution adopted by this application to solve its technical problem is: a high-efficiency grinding device for soybean protein powder, including a support, a grinding shell and a sieving component. The grinding shell is fixed on the support, and the sieving component is installed at the lower end inside the grinding shell, suitable for sieving the ground soybean powder. A grinding motor is installed on the grinding shell, and the output end of the grinding motor extends into the grinding shell and is equipped with a first long rotating rod. A second long rotating rod is rotatably connected inside the grinding shell. One end of the first long rotating rod extends out of the grinding shell and is equipped with a main gear. One end of the second long rotating rod extends out of the grinding shell and is equipped with an auxiliary gear that meshes with the main gear. Grinding rollers are installed on both the first long rotating rod and the second long rotating rod. The grinding shell is rotatably connected to both sides of a transmission rod, one end of which extends outside the grinding shell and is fitted with a transmission gear that meshes with the main gear and the auxiliary gear. Each transmission rod is fitted with a cleaning roller adapted to the grinding roller, which is suitable for cleaning residual soybean powder on the surface of the grinding roller.

[0007] Furthermore, the screening assembly includes an assembly plate and springs, with multiple assembly plates fixed inside the grinding shell and multiple springs fixed on the assembly plates. The upper end of each spring is fixed with a screening plate located below the grinding roller.

[0008] Furthermore, a servo motor is installed at one end of the grinding shell, and the output end of the servo motor extends into the grinding shell and is equipped with a connecting rod. At least two cams are installed on the connecting rod, and a vibrating seat adapted to the cams is installed on the screening plate.

[0009] Furthermore, the other end of the connecting rod is rotatably connected to the grinding shell.

[0010] Furthermore, the spring causes the screening plate to maintain a downward motion tendency.

[0011] Furthermore, a feed hopper is installed through the upper end of the grinding shell, and a discharge hopper is installed through the lower end of the grinding shell.

[0012] Furthermore, a guide plate is fixed inside the grinding shell above the grinding roller.

[0013] Furthermore, a sealing plate is installed on one side of the grinding shell.

[0014] The beneficial effects of this application are: the soybean protein powder high-efficiency grinding device provided by this application, through the main gear and auxiliary gear rotating, drives the transmission rod to rotate by means of the transmission gear meshing with it, thereby making the cleaning roller operate synchronously, which can remove the soybean powder remaining on the surface of the grinding roller in a timely manner, reducing the impact of soybean powder accumulation on grinding accuracy and product quality.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] like Figures 1-5 As shown, this application provides a high-efficiency soybean protein powder grinding device, including a support 1, a grinding shell 2, and grinding rollers 7. The support 1, as the supporting structure of the entire device, is made of high-strength steel and has sufficient strength and stability to support the weight of the grinding shell 2 and other components. The grinding shell 2 is welded and fixed to the support 1, forming a grinding space inside for grinding soybean powder. A feed hopper 3 is installed through the upper end of the grinding shell 2. The feed hopper 3 is funnel-shaped and welded and fixed to the grinding shell 2 to facilitate the pouring and guiding of soybean powder. A guide plate 21 is welded and fixed inside the grinding shell 2 above the grinding rollers 7. The guide plate 21 guides the soybean powder entering from the feed hopper 3 to between the two grinding rollers 7, ensuring that the soybean powder can enter the grinding area evenly, improving the grinding efficiency and uniformity.

[0020] A grinding motor 4 is bolted to the grinding housing 2, providing power for the entire grinding process. The output end of the grinding motor 4 extends into the grinding housing 2 and is fitted with a first long rotating rod 5. The first long rotating rod 5 is rotatably connected to the grinding housing 2 via bearings to ensure stable rotation. A second long rotating rod 6 is rotatably connected inside the grinding housing 2, also rotatably connected to the grinding housing 2 via bearings.

[0021] One end of the first long rotating rod 5 extends outside the grinding shell 2 and is equipped with a main gear 8. One end of the second long rotating rod 6 extends outside the grinding shell 2 and is equipped with an auxiliary gear 9 that meshes with the main gear 8. When the grinding motor 4 is working, it drives the first long rotating rod 5 to rotate. The first long rotating rod 5 drives the second long rotating rod 6 to rotate through the meshing transmission of the main gear 8 and the auxiliary gear 9. This causes the grinding roller 7, which is fixed on the first long rotating rod 5 and the second long rotating rod 6, to rotate relative to each other, thus grinding the soybean powder that has entered the grinding area.

[0022] To promptly remove residual soybean powder from the surface of the grinding roller 7, transmission rods 10 are rotatably connected to both sides of the grinding shell 2. One end of each transmission rod 10 extends outside the grinding shell 2 and is fitted with a transmission gear 11 that meshes with the main gear 8 and auxiliary gear 9. When the main gear 8 and auxiliary gear 9 rotate, the transmission gear 11 drives the transmission rods 10 to rotate, which in turn causes the cleaning roller 12 mounted on the transmission rods 10 to rotate. The surface of the cleaning roller 12 is made of a soft and wear-resistant material, effectively removing soybean powder from the surface of the grinding roller 7 without damaging it.

[0023] A sieving assembly is installed at the lower end of the grinding shell 2 for sieving the ground soybean flour. The sieving assembly includes an assembly plate 13 and springs 14. Multiple assembly plates 13 are welded and fixed inside the grinding shell 2, and multiple springs 14 are welded and fixed to the assembly plates 13. A sieving plate 15 located below the grinding roller 7 is welded and fixed to the upper end of the springs 14. The springs 14 keep the sieving plate 15 moving downwards and provide a restoring force for the vibration of the sieving plate 15. A servo motor 16 is bolted to one end of the grinding shell 2. The output end of the servo motor 16 extends into the grinding shell 2 and is mounted with a connecting rod 17. The other end of the connecting rod 17 is rotatably connected to the grinding shell 2 via a bearing. Two cams 18 are welded and fixed to the connecting rod 17. The cams 18 are disc-shaped, and a vibration seat 19 adapted to the cams 18 is welded and fixed to the sieving plate 15. When the servo motor 16 is working, it drives the connecting rod 17 and the cam 18 to rotate. When the cam 18 contacts the vibrating seat 19, it pushes the vibrating seat 19 and the sieve plate 15 to move upward. When the cam 18 disengages from the vibrating seat 19, the sieve plate 15 moves downward under the action of the spring 14, thereby causing the sieve plate 15 to vibrate, improving the sieve efficiency and reducing the situation of soybean powder clogging the sieve holes.

[0024] A discharge hopper 20 is installed through the lower end of the grinding shell 2. After the ground soybean powder is screened by the screening plate 15, the qualified soybean powder is discharged through the discharge hopper 20, while the unqualified soybean powder remains on the screening plate 15 and continues to be ground. A sealing plate 22 is installed on one side of the grinding shell 2. The sealing plate 22 is connected to the grinding shell 2 by bolts, which facilitates the disassembly and cleaning of the coarse powder on the screening plate 15. After the equipment has been used for a period of time, the operator can disassemble the sealing plate 22 to collect the coarse powder on the screening plate 15 and pour it back into the feed hopper 3 to achieve cyclic grinding.

[0025] Working principle: First, the soybean powder that has been preliminarily crushed and had its outer shell removed is poured into the feed hopper 3. Under the inclined guidance of the guide plate 21, the soybean powder slides evenly down the 45° guide slope to the grinding area between the two grinding rollers 7. At this time, the grinding motor 4 is started by the external 220V power supply and PLC controller. The output shaft of the grinding motor 4 drives the first long rotating rod 5 to rotate. The first long rotating rod 5 drives the second long rotating rod 6 to rotate through the meshing transmission of the main gear 8 and the auxiliary gear 9, so that the two grinding rollers 7 form a relative rotating grinding motion. The surface of the grinding rollers 7 is engraved with interlaced spiral patterns to achieve the grinding of soybean powder. During the grinding process, when the main gear 8 and the auxiliary gear 9 rotate, the transmission gear 11 meshing with them on the outside rotates synchronously. The transmission gear 11 drives the transmission rod 10 to rotate through a key connection, causing the cleaning roller 12 fixed on the transmission rod 10 to rotate in the opposite direction to the grinding roller 7. The cleaning roller 12 is made of food-grade silicone material with soft protrusions on its surface, which can penetrate into the gaps in the grooves of the grinding roller 7 and scrape off the adhering soybean powder particles through friction. The cleaning roller 12 can complete one cleaning cycle every time it rotates, reducing the accumulation of residual soybean powder that increases the rotational resistance of the grinding roller 7. At the same time, it reduces the oxidation and deterioration of soybean powder due to long-term residue, ensuring the hygiene and safety of the raw materials to be ground later. The ground soybean powder falls onto the sieve plate 15 via the guide slope below the grinding roller 7. Soybean powder generated during the cleaning roller 12's cleaning of the grinding roller 7 also falls onto the sieve plate 15 under gravity. At this time, the servo motor 16 is started via an external power supply and controller. The servo motor 16 drives the connecting rod 17 to rotate, and the two symmetrically arranged cams 18 on the connecting rod 17 rotate synchronously. When the protruding part of the cam 18 presses against the vibrating seat 19, the sieve plate 15 overcomes the tension of the four springs 14 and moves upward. When the cam 18 rotates to the concave part, the sieve plate 15 moves downward under the reset action of the springs 14, forming reciprocating vibration. Under the vibration, qualified fine powder falls through the sieve holes into the discharge hopper 20, and then is discharged from the discharge hopper 20 into an external storage container. Coarse powder that does not pass through the sieve holes remains on the sieve plate 15. After the equipment has been used for a period of time, the operator can remove the sealing plate 22 to collect the coarse powder and pour it back into the feed hopper 3, thus achieving cyclic grinding.

[0026] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
