Abstract
Description
Technical Field
[0001] The utility model specifically relates to the technical field of lactose production, and specifically is a stirring device for bovine lactose preparation with auxiliary stirring and guiding discharging. Background Technique
[0002] Lactose is a unique carbohydrate in human and mammalian milk. It is a disaccharide composed of glucose and galactose. Like other sugars, lactose is a source of human heat energy. One-fourth of the total calories in cow's milk come from lactose. In addition to supplying human energy, lactose has a physiological significance different from other sugars. Lactose is not digested and absorbed in the human stomach and can directly reach the intestine. In the human intestine, lactose is easily decomposed into glucose and galactose by lactase and then absorbed.
[0003] Lactose crystallization, that is, cooling crystallization of concentrated sugar solution. Currently, the methods that can be adopted are: flat pan natural crystallization method. Using the flat pan natural crystallization method means that the temperature is cooled to below 30°C for crystallization under stirring, and the crystallization time is relatively long. In the domestic production technologies of cooling crystallization of glucose or lactose with grains or other raw materials, small horizontal jacketed cooling crystallizers or other forms of disk cooling crystallizers are often used. For small horizontal jacketed cooling crystallizers, the contact between materials and cooling devices is not sufficient, and the cooling is relatively slow, affecting the crystallization effect. There is also a crystallization device on the market. There is a cooling coil in the crystallizer, and the stirring shaft drives the stirring blades to stir the lactose solution. However, during the stirring process, the contact range between the stirring blades and the lactose solution is small, and the lactose solution at the inner side of the container cannot effectively contact the stirring blades, resulting in poor stirring uniformity of the lactose solution.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to Figures 1 - 5, in the embodiment of the present utility model, a stirring device for preparing milk sugar with auxiliary stirring and guiding discharging includes a stirring tank 10, a lateral stirrer 15 and a swinging stirrer 30 arranged inside the stirring tank 10. The stirring tank 10 includes a tank body and an upper cover 20 arranged at the upper opening of the tank body. The swinging stirrer 30 is installed in the upper cover 20, and the upper cover 20 is detachably connected to the tank body. After the upper cover 20 is connected to the tank body, the lower part of the swinging stirrer 30 extends into the interior of the tank body 10 to stir the lactose solution inside the tank body 10 and assist in discharging the lactose crystals. The swinging stirrer 30 includes a frame 31, a first rotating shaft 32, a second rotating shaft 34 and a third rotating shaft 36. A bearing seat is arranged on one side of the frame 31, and the first rotating shaft 32 is installed on the bearing seat. An eccentric sleeve 33 is connected to the eccentric part at the lower end of the first rotating shaft 32. The second rotating shaft 34 is rotatably installed on the sleeve 33. When the first rotating shaft 32 is in a rotating state, it drives the second rotating shaft 34 to rotate around the first rotating shaft 32 as the axis. The lower end of the second rotating shaft 34 is connected to the third rotating shaft 36. The third rotating shaft 36 includes a first shaft body 361 and a second shaft body 362. One end of the second shaft body 362 is rotatably connected to the first shaft body 361, and a stirring head 37 is installed at the other end of the second shaft body 362. A rotating motor is arranged on the side of the first shaft body 361 facing the second shaft body 362, and the output end of the rotating motor is connected to the second shaft body 362. The rotating motor is used to drive the second shaft body 362 to rotate. It can be understood that when the second rotating shaft 34 rotates around the first rotating shaft 32 as the axis, the rotating motor drives the second shaft body 362 to rotate self - sufficiently, so that while the swinging stirrer 30 rotates obliquely inside the tank body, it drives the stirring head 37 to rotate self - sufficiently. It should be noted that in the embodiment of the present application, the third rotating shaft 36 is obliquely arranged at the lower end of the second rotating shaft 34. After the swinging stirrer 30 extends into the interior of the tank body, the stirring head 37 at the lower end of the third rotating shaft 36 is located at the side of the bottom of the tank body, so as to stir the lactose solution at the bottom of the tank body by using the stirring head 37, improve the stirring uniformity of the lactose solution. In addition, when the lactose solution crystallizes, the stirring head 37 can promote the flow of the lactose crystals at the side of the bottom of the tank body and assist in discharging the lactose crystals.
[0023] In the embodiment of the present application, a feed inlet 12 is arranged at the upper part of the tank body, and a discharge outlet 13 is opened at the bottom of the tank body. The feed inlet 12 is used to add lactose solution and auxiliary materials into the interior of the tank body, and the discharge outlet 13 is used to discharge lactose crystals.

The active connection block 341 is in a spherical structure or a frustum structure. When the second rotating shaft 34 rotates, the curved surface of the active connection block 341 remains in contact with the installation opening, thereby improving the rotation stability of the second rotating shaft 34.
[0025] In an embodiment of the present application, a mounting plate 342 is fixedly installed at the lower end of the second rotating shaft 34. A connecting shaft 343 is provided at the bottom of the mounting plate 342. The upper end of the third rotating shaft 36 is obliquely installed on the connecting shaft 343;
[0026] As an embodiment of the present application, one end of the connecting shaft 343 is fixedly connected to the mounting plate 342, and the other end of the connecting shaft 343 is fixedly connected to the third rotating shaft 36; As another embodiment of the present application, one end of the connecting shaft 343 is rotatably connected to the mounting plate 342. A control motor and a gear set for controlling the rotation of the connecting shaft 343 are provided on the mounting plate 342. When the connecting shaft 343 is in a rotating state, it drives the third rotating shaft 36 to rotate about the axis of the connecting shaft 343, further increasing the stirring range of the stirring head 37.
[0027] In addition, in an embodiment of the present application, a driving motor 21 is fixedly installed on the upper cover 20. The output end of the driving motor 21 is connected to the first rotating shaft 32.
[0028] Please refer to again Figure 2 and Figure 5 In an embodiment of the present application, a rotating shaft 16 is also rotatably installed inside the upper cover 20.
