Description

Technical Field

[0001] This utility model relates to the field of dairy processing technology, specifically to a stirring device for dairy product production and processing. Background Technology

[0002] Dairy products refer to various foods made using cow's milk or sheep's milk and their processed products as the main raw materials, with or without the addition of appropriate amounts of vitamins, minerals and other auxiliary materials, and processed under the conditions required by laws, regulations and standards.

[0003] During the mixing and stirring process of dairy raw materials, some insoluble substances in the solid raw materials usually float on the surface of the raw materials or stick to the inner wall of the mixing tank. Incorporating air into the dairy products during the stirring process can improve the stirring effect, but the addition of air will produce foam on the surface of the dairy products. Moreover, the existing mixing devices have a simple structure and low mixing efficiency, and cannot solve the problems of solid raw materials sticking to the inner wall of the mixing tank and the foam produced by the addition of air on the surface of the dairy products during the stirring process. Utility Model Content

[0004] The purpose of this invention is to provide a stirring device for dairy product production and processing, which solves the problems of solid raw materials sticking to the inner wall of the stirring tank and the formation of foam on the surface of dairy products due to the addition of air during the stirring process.

[0005] To address the aforementioned technical problems, this utility model provides a mixing device for dairy product processing, comprising a mixing tank and an inner insulation tank. Both the mixing tank and the inner insulation tank are cylindrical and coaxial. The inner insulation tank is fixedly connected inside the mixing tank. An insulation cavity exists between the inner wall of the mixing tank and the outer wall of the inner insulation tank. The inner insulation tank contains auger blades, a lower rotating tube, and an upper rotating tube.

The auger blades are coaxial with the mixing tank and the inner insulation tank. The auger blades are hollow at their center along the height direction. A first drive motor is fixedly connected to the top surface of the mixing tank. The output shaft of the first drive motor passes through the top wall of the mixing tank and the top wall of the inner insulation tank. The output shaft of the first drive motor is fixedly connected to the upper rotating tube. A discharge cylinder is fixedly connected to the bottom wall of the mixing tank. The upper end of the discharge cylinder passes through the bottom wall of the mixing tank and the bottom wall of the inner insulation tank. The upper end of the discharge cylinder is connected to the lower rotating tube. A control valve is connected to the lower end of the discharge cylinder. An air inlet pipe is fixedly connected to the side wall of the discharge cylinder. The air inlet pipe passes through the side wall of the discharge cylinder and is inclined. The height of the end of the air inlet pipe inside the discharge cylinder is greater than the height of the end of the air inlet pipe on the outer wall of the discharge cylinder. The outer wall of the auger blades is rotatably connected to the inner wall of the inner insulation tank.

[0006] Furthermore, it includes auxiliary components, including a rotating cylinder, an electric telescopic rod, and a first scraper. The rotating cylinder passes through the top wall of the mixing tank and the top wall of the inner insulation tank, and is rotatably connected to the top wall of the mixing tank and the top wall of the inner insulation tank. The lower end of the rotating cylinder is located inside the inner insulation tank. The rear end of the electric telescopic rod is fixedly connected to the lower end of the rotating cylinder, and the first scraper is fixedly connected to the piston rod of the electric telescopic rod.

[0007] Furthermore, the upper end of the rotating cylinder is located outside the mixing tank, and a gear ring is fixedly connected to the outer wall of the upper end of the rotating cylinder. A second drive motor is rotatably connected to the outer top surface of the mixing tank via a bracket, and a drive gear is fixedly connected to the output shaft of the second drive motor, which meshes with the gear ring.

[0008] Furthermore, a connecting pipe is slidably connected to the top wall of the mixing tank and the top wall of the inner insulation tank. The connecting pipe is an "n" shape composed of one horizontal pipe and two vertical pipes. Holes are provided on the top wall of the mixing tank and the top wall of the inner insulation tank for the connecting pipe to pass through. One vertical pipe of the connecting pipe is slidably connected to the hole in the top wall of the mixing tank and the top wall of the inner insulation tank. A suction head is fixedly connected to the end of the vertical pipe of the connecting pipe that is slidably connected to the top wall of the mixing tank and the top wall of the inner insulation tank. The suction head is located inside the inner insulation tank. A suction pump is fixedly connected to the end of the other vertical pipe of the connecting pipe that is not inserted into the mixing tank and the inner insulation tank.

[0009] Furthermore, a limiting sleeve is fixedly connected to the outer top surface of the mixing tank.

The center of the auger blades is hollow, and the outer wall of the auger blades is rotatably connected to the inner wall of the inner insulation barrel. When the auger blades rotate, they can stir the raw materials added to the mixing barrel evenly. During the stirring process, the air inlet pipe can continuously input clean and stable gas into the inner insulation barrel, and the gas can mix the mixture inside the inner insulation barrel vertically. The outer wall of the auger blades and the second scraper scrape off the solid raw materials attached to the inner wall of the inner insulation barrel. The electric telescopic rod can extend and retract to adjust the height of the first scraper. The lower end of the first scraper contacts the liquid surface inside the inner insulation barrel, which can scrape the foam generated during the mixing of dairy products to below the suction head. The suction head can suck out and remove the foam or impurities floating on the liquid surface. The lifting block set on the upper end of the drive gear can lift the suction pump, connecting pipe and suction head as a whole when the first scraper rotates to below the suction head, so as to avoid interference between the first scraper and the suction head when rotating.

[0021] like Figures 1-4As shown, this utility model discloses a stirring device for dairy product production and processing, comprising a stirring tank 1 and an inner insulation tank 20. Both the stirring tank 1 and the inner insulation tank 20 are cylindrical and coaxial. The inner insulation tank 20 is fixedly connected inside the stirring tank 1. An insulation cavity exists between the inner wall of the stirring tank 1 and the outer wall of the inner insulation tank 20. The inner insulation tank 20 contains an auger blade 8, a lower rotating tube 18, and an upper rotating tube 19. The upper end of the upper rotating tube 19 is rotatably connected to the top surface of the inner insulation tank 20, and the lower rotating tube 18 is rotatably connected to the bottom surface of the inner insulation tank 20. The lower rotating tube 18, the upper rotating tube 19, the stirring tank 1, and the inner insulation tank 20 are coaxial. The upper and lower ends of the auger blade 8 are fixedly connected to the upper rotating tube 19 and the lower rotating tube 18, respectively. The auger blade 8 is coaxial with the stirring tank 1 and the inner insulation tank 20. The shaft and the center of the auger blades 8 along the height direction are hollow. The first drive motor 2 is fixedly connected to the top surface of the mixing tank 1. The output shaft of the first drive motor 2 passes through the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20. The output shaft of the first drive motor 2 is fixedly connected to the upper rotating tube 19. The discharge cylinder 5 is fixedly connected to the bottom wall of the mixing tank 1. The upper end of the discharge cylinder 5 passes through the bottom wall of the mixing tank 1 and the bottom wall of the inner insulation tank 20. The upper end of the discharge cylinder 5 is connected to the lower rotating tube 18. The lower end of the discharge cylinder 5 is connected to the control valve 7. The air inlet pipe 6 is fixedly connected to the side wall of the discharge cylinder 5. The air inlet pipe 6 passes through the side wall of the discharge cylinder 5. The air inlet pipe 6 is inclined. The height of the end of the air inlet pipe 6 inside the discharge cylinder 5 is greater than the height of the end of the air inlet pipe 6 on the outer wall of the discharge cylinder 5. The outer wall of the auger blades 8 is rotatably connected to the inner wall of the inner insulation tank 20.

[0022] Multiple air inlet pipes 6 are fixedly connected to the side wall of the discharge cylinder 5. The multiple air inlet pipes 6 are evenly distributed around the axis of the discharge cylinder 5. In this embodiment, there are two air inlet pipes 6.

[0023] A second scraper 21 is fixedly connected to the outer wall of the lower rotating tube 18. The second scraper 21 is rotatably connected to the inner wall of the inner insulation barrel 20 away from the side wall of the lower rotating tube 18. Multiple second scrapers 21 are fixedly connected to the outer wall of the lower rotating tube 18. The multiple second scrapers 21 are evenly distributed around the axis of the lower rotating tube 18. In this embodiment, there are two second scrapers 21.

[0024] The outer wall of the auger blade 8 is rotatably connected to the inner wall of the inner insulation barrel 20, and the side wall of the second scraper 21 away from the lower rotating pipe 18 is rotatably connected to the inner wall of the inner insulation barrel 20. Both are for scraping off the solid raw materials adhering to the inner wall of the inner insulation barrel 20. However, in order to ensure the smooth rotation of the auger blade 8 and the second scraper 21, the outer diameter of the auger blade 8 and the outer diameter of the second scraper 21 cannot be set to be the same as the inner diameter of the inner insulation barrel 20. If the dimensions are the same, the outer diameter of the auger blade 8 and the second scraper 21 will interfere with the inner insulation barrel 20. Instead, there should be a small gap between the outer diameter of the auger blade 8 and the outer diameter of the second scraper 21 and the inner diameter of the inner insulation barrel 20.

[0025] When the auger blades 8 rotate, they can stir the dairy mixture inside the inner insulation tank 20 and clean the deposits on the inner wall of the inner insulation tank 20. While the auger blades 8 are stirring the dairy products inside the inner insulation tank 20, two inclined air inlet pipes 6 located inside the discharge cylinder 5 can inject stable gas into the inner insulation tank 20 to stir the dairy products inside the inner insulation tank 20 in the vertical direction.

[0026] When the auger blades 8 rotate continuously, they can drive the second scraper 21 fixedly installed on the outside of the lower rotating tube 18 to stir the lower end of the inner insulation barrel 20. The outer wall of the second scraper 21 also cleans the deposits on the inner wall of the insulation barrel 20. At the same time, the lower end of the second scraper 21 contacts the inner bottom surface of the inner insulation barrel 20. When the second scraper 21 rotates, it will stir up the sediment on the bottom surface of the inner insulation barrel 20 and mix it thoroughly with other substances.

[0027] This utility model also includes auxiliary components, which include a rotating cylinder 3, an electric telescopic rod 9, and a first scraper 10. The rotating cylinder 3 penetrates the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20, and is rotatably connected to the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20. The lower end of the rotating cylinder 3 is located inside the inner insulation tank 20. The rear end of the electric telescopic rod 9 is fixedly connected to the lower end of the rotating cylinder 3. The first scraper 10 is fixedly connected to the piston rod of the electric telescopic rod 9, and the cross-sectional shape of the first scraper 10 is triangular. The upper end of the rotating cylinder 3 is located outside the mixing tank 1, and a gear ring 4 is fixedly connected to the outer wall of the upper end of the rotating cylinder 3. A second drive motor 15 is rotatably connected to the outer top surface of the mixing tank 1 through a bracket. A drive gear 14 is fixedly connected to the output shaft of the second drive motor 15, and the drive gear 14 meshes with the gear ring 4. A connecting pipe 11 is slidably connected to the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20. The connecting pipe 11 is composed of an "n" shape consisting of one horizontal pipe and two vertical pipes. Holes for the connecting pipe 11 to pass through are provided on the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20. One vertical tube of the connecting pipe 11 is slidably connected to the hole in the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20. A suction head 12 is fixedly connected to the end of the vertical tube of the connecting pipe 11 slidably connected to the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20. The suction head 12 is located inside the inner insulation tank 20 and is a conical barrel shape with the inner diameter of the top surface smaller than the inner diameter of the bottom surface. The connecting pipe 11 is not inserted into the other part of the mixing tank 1 and the inner insulation tank 20. A suction pump 16 is fixedly connected to the end of a vertical pipe; a limiting sleeve 13 is fixedly connected to the top surface of the mixing tank 1, and the limiting sleeve 13 is coaxial with the holes on the top wall of the mixing tank 1 and the top wall of the inner insulation tank 20 for the connecting pipe 11 to pass through. One vertical pipe of the connecting pipe 11 is slidably connected inside the limiting sleeve 13; the suction pump 16 is slidably connected to the top surface of the drive gear 14, and a lifting block 17 is fixedly connected to the top surface of the drive gear 14. The lifting block 17 and the first scraper 10 are located on the same vertical plane.

[0028] The first scraper 10 can be adjusted by the electric telescopic rod 9 to contact the liquid surface of the dairy products inside the inner insulation tank 20. When the first scraper 10 rotates, it can clean the foam and floating impurities on the liquid surface. The second drive motor 15 drives the drive gear 14 to rotate. Under the meshing action between the drive gear 14 and the gear ring 4, the rotating cylinder 3 can be driven to rotate. The rotation of the rotating cylinder 3 drives the first scraper 10 to rotate on the liquid surface of the dairy products inside the inner insulation tank 20 through the electric telescopic rod 9. The suction pump 16 sucks the foam and floating objects floating on the liquid surface of the dairy products through the connecting pipe 11 and the suction head 12. The limiting sleeve 13 can protect and limit the connecting pipe 11, and prevent the connecting pipe 11 from being blocked. There may be bending or other issues at the connection point with the mixing tank 1; the lifting block 17 can be set as an arc shape with a smooth upper surface and a protrusion in the middle position. By rotating the drive gear 14, the lifting block 17 can be moved to the bottom of the suction pump 16, which can lift the suction pump 16, the connecting pipe 11 and the suction head 12 as a whole upward, thereby avoiding interference between the suction head 12 and the first scraper 10. It should be noted that the position and shape of the lifting block 17 should be designed in relation to the position and shape of the first scraper 10, so that when the lifting block 17 moves to the bottom of the suction pump 16 and lifts the suction pump 16, the connecting pipe 11 and the suction head 12 as a whole upward, the suction head 12 will not interfere with the first scraper 10.
