Description

Technical Field

[0001] This application relates to the technical field of soybean protein powder processing equipment, specifically a soybean protein powder cooling and temperature reduction device. Background Technology

[0002] In the production process of soybean protein powder, the protein powder material after high-temperature treatment (such as cooking, concentration, spray drying, etc.) is usually in a high-temperature state. If it is not effectively cooled in time, it will lead to a series of problems. For example, high temperature will denature the protein, destroy its nutritional components and functional properties, and affect the product quality; the material is prone to moisture absorption and clumping when it is in a high-temperature state for a long time, which will reduce its fluidity and make it unfavorable for subsequent storage and processing; high-temperature environment may also breed microorganisms, affecting the hygiene and safety of the product.

[0003] Existing soybean protein powder cooling devices often fail to effectively disperse and vibrate the incoming soybean powder during the feeding process. In practice, most of the material falls directly into the cooling container, and some material tends to clump together, making it difficult for the cooling medium to contact the material evenly. This reduces the cooling efficiency of the soybean protein powder. Therefore, it is necessary to design a soybean protein powder cooling 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 soybean protein powder cooling device, which solves the problems of some existing soybean protein powder cooling devices being inconvenient to effectively disperse and vibrate the material during the feeding process, resulting in some material easily accumulating into lumps, uneven contact with the cooling medium, and low cooling efficiency.

[0006] The technical solution adopted by this application to solve its technical problem is: a soybean protein powder cooling and temperature reduction device, including a support, a stirring drum and a cooling component. The stirring drum is fixed on the support, the cooling component is installed at the lower end of the stirring drum, a cover is installed on the stirring drum, and a feed hopper is connected through the front end of the cover. A rotating rod is connected to the stirring drum by a power drive, and a ribbon stirring blade is fixed on the rotating rod.

[0007] A guide plate is hinged to the mixing drum and located below the feed hopper. Multiple distributing cones are fixed at intervals at the rear end of the guide plate. Connecting plates located below the guide plate are fixed on both sides of the mixing drum. Springs are fixed on the connecting plates, and the upper ends of the springs are fixedly connected to the guide plate.

[0008] A short rod located below the guide plate is rotatably connected to the mixing drum. A cam is fixed to the rear end of the short rod. A vibrating seat adapted to the cam is fixed to the guide plate. The front ends of the rotating rod and the short rod extend outside the mixing drum and are equipped with sprockets. Chains are sleeved on the two sprockets.

[0009] Furthermore, the spring causes the guide plate to maintain a downward motion tendency.

[0010] Furthermore, a mixing motor is installed at the rear end of the mixing drum, and the output end of the mixing motor is connected to the rear end of the rotating rod.

[0011] Furthermore, baffles are fixed on both sides of the guide plate.

[0012] Furthermore, the cooling assembly includes a cooling shell and a cooling tube. The cooling shell is fixed to the lower end of the stirring drum, and the cooling tube is installed inside the cooling shell. The rear end of the cooling tube extends to the outside of the cooling shell and is fixed with a liquid inlet head, and the front end of the cooling tube extends to the outside of the cooling shell and is fixed with a liquid outlet head.

[0013] Furthermore, a heat-conducting arc plate located inside the stirring drum is installed on the cooling shell.

[0014] Furthermore, a slide gate valve is installed through the rear end of the mixing drum.

[0015] The beneficial effects of this application are as follows: The soybean protein powder cooling and temperature reduction device provided in this application, by setting up a guide plate, a distributing cone, a spring, a short rod, a cam, and a vibrating seat, allows the soybean protein powder to enter from the feed inlet and fall onto the guide plate during the feeding process. At the same time, the power drives the rotating rod to rotate, and the rotating rod drives the short rod to rotate through the sprocket and chain. When the cam on the short rod rotates, it will contact the vibrating seat, causing the guide plate to vibrate. The function of the spring is to keep the guide plate moving downward and enhance the vibration effect. The distributing cone on the vibrating guide plate can further disperse the material, allowing it to enter the mixing drum evenly, which is convenient for subsequent cooling and mixing.

[0024] 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.

[0025] 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 skilled in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figures 1-5 As shown, this application provides a soybean protein powder cooling device, including a support frame 1 and a mixing drum 2. The support frame 1 is welded from Q235 carbon steel and has an overall frame structure with sufficient strength and stability to support the weight of the mixing drum 2 and the materials inside. The mixing drum 2 is a cylindrical stainless steel container made of 304 stainless steel with a smooth inner wall for easy cleaning and material flow. A mixing motor 5, model Y132M-4, with a rated power of 7.5kW, is bolted to the rear end of the mixing drum 2 and connected to the rear end of a rotating rod 6 via a coupling to provide power for the rotation of the rotating rod 6.

[0027] A cover 3 is bolted to the mixing drum 2. A feed hopper 4 is connected to the front end of the cover 3 and welded to the cover 3. The feed hopper 4 is funnel-shaped to facilitate the smooth entry of materials into the mixing drum 2. A guide plate 8 is hinged to the mixing drum 2 and located below the feed hopper 4. The guide plate 8 is made of stainless steel and has an angle of 15°-30° with the horizontal. Multiple distribution cones 9 are fixed at intervals at the rear end of the guide plate 8. The distribution cones 9 are truncated cones made of stainless steel and are welded to the guide plate 8 to effectively disperse materials.

[0028] Connecting plates 10, rectangular steel plates, are welded and fixed to both sides of the mixing drum 2, located below the guide plate 8. Springs 11, compression springs with a diameter of 20mm, a free length of 150mm, and an elastic modulus of 50N / mm, are fixed to each connecting plate 10. The upper ends of the springs are welded and fixed to the guide plate 8, ensuring the guide plate 8 maintains a downward movement trend. Baffles 17 are welded and fixed to both sides of the guide plate 8, guiding the material flow along the guide plate 8 and allowing it to smoothly enter the mixing drum 2.

[0029] A short rod 12, located below the guide plate 8, is rotatably connected to the mixing drum 2. The short rod 12 is a stainless steel shaft and is mounted on the mixing drum 2 via bearings. A cam 13 is welded and fixed to the rear end of the short rod 12. The cam 13 is a disc cam made of 45# steel with a surface hardening treatment and a hardness of HRC45-50. A vibration seat 14, adapted to the cam 13, is welded and fixed to the guide plate 8. The vibration seat 14 is made of stainless steel, and the surface in contact with the cam 13 is smooth to reduce wear. During rotation, the cam 13 intermittently contacts the vibration seat 14, thereby causing the guide plate 8 to vibrate.

[0030] The front ends of both the rotating rod 6 and the short rod 12 extend outside the mixing drum 2 and are equipped with sprockets 15. Chains 16 are fitted on the two sprockets 15 to ensure that the transmission ratio between the rotating rod 6 and the short rod 12 is 1:1, so that the rotation of the cam 13 is synchronized with the rotation of the rotating rod 6.

[0031] The cooling assembly includes a cooling shell 18 and a cooling tube 19. The cooling shell 18 is a plate-shaped stainless steel shell, welded and fixed to the lower end of the stirring drum 2. The cooling tube 19 is welded and fixed inside the cooling shell 18, and is made of copper. Its rear end extends to the outside of the cooling shell 18 and is welded and fixed with a liquid inlet head 20. Its front end extends to the outside of the cooling shell 18 and is welded and fixed with a liquid outlet head 21. Both the liquid inlet head 20 and the liquid outlet head 21 are quick connectors, which facilitate connection to the cooling medium supply source.

[0032] Working principle: First, turn on the power supply of the mixing motor 5 to put it into standby mode, and connect the supply source of the cooling medium, such as coolant, to the inlet head 20 to prepare for the subsequent cooling process.

[0033] Next, the high-temperature treated soybean protein powder is poured into the feed hopper 4. At this time, the soybean protein powder will fall onto the guide plate 8. Then, the mixing motor 5 is started, and its output end drives the rotating rod 6 to start rotating. The ribbon stirring blade 7 fixed on the rotating rod 6 also rotates, which initially stirs the material in the mixing drum 2. At the same time, the sprocket 15 at the front end of the rotating rod 6 drives the sprocket 15 at the front end of the short rod 12 to rotate through the chain 16, so that the short rod 12 starts to rotate. The cam 13 at the rear end of the short rod 12 will intermittently contact the vibrating seat 14 on the guide plate 8 during the rotation, so that the guide plate 8 vibrates. Since the spring 11 always keeps the guide plate 8 in a downward movement trend, this further enhances the vibration effect. The distribution cone 9 on the guide plate 8 can further disperse the accumulated soybean protein powder during the vibration of the guide plate 8, so that it enters the mixing drum 2 evenly and reduces the situation of some material accumulating into clumps.

[0034] Inside the mixing drum 2, the ribbon stirring blades 7 rotate continuously, making the soybean protein powder more uniform and greatly increasing the contact area between the material and the cooling medium, which is beneficial to improving the cooling efficiency. At the same time, the cooling medium enters the cooling pipe 19 from the liquid inlet 20. When it flows through the cooling pipe 19 inside the cooling shell 18, it absorbs the heat in the mixing drum 2 and then discharges from the liquid outlet 21. The heat-conducting arc plate 23 installed on the cooling shell 18 is located inside the mixing drum 2 and can transfer the heat in the mixing drum 2 to the cooling pipe 19, further improving the cooling effect.

[0035] Once the temperature monitoring confirms that the soybean protein powder has cooled to a suitable temperature, the discharge speed and discharge amount of the material are controlled by adjusting the opening of the baffle valve 22, and the cooled soybean protein powder is discharged from the rear end of the mixing drum 2 for subsequent storage or processing operations.

[0036] 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.
