Abstract
Description
Technical Field
[0001] This application relates to the field of mixing equipment technology, and particularly to a mixing trap and mixing trapping equipment. Background Technology
[0002] In production practices in the food, pharmaceutical, and chemical industries, some raw materials (such as casein in dairy products) require multiple processing steps, including collection, stirring, washing, and crushing. Most existing equipment can only perform one or two of these processing steps individually, often necessitating multiple transfers of raw materials between different machines. These multiple transfers increase the risk of microbial growth, foreign matter introduction, and chemical contamination, and may even cause denaturation, affecting the quality of the final product. Furthermore, multiple transfers extend production cycles and limit efficiency. Therefore, there is an urgent need for production equipment capable of performing multiple processing steps to minimize the number of raw material transfers, thereby improving production efficiency and product quality.

The purpose of this application is to provide a stirring trap that can realize multiple processing steps such as stirring, trapping, washing and filtering, and preliminary crushing within a production device by adjusting the direction and speed.
[0004] This application provides a stirring trap for installation inside the tank of a stirring trap device.
[0005] The stirring trap includes a deformable trapping net, an arc-shaped trapping net, and a rotating main shaft.
[0006] The deformable trapping net is connected to the rotating main shaft so that the deformable trapping net can rotate with the rotating main shaft.
[0007] The deformable trapping net extends radially and axially along the main rotating axis, and the arc-shaped trapping net connects to the radial side of the deformable trapping net, extending circumferentially and axially along the main rotating axis.
[0008] The deformable trapping net includes multiple trapping net units, multiple rotating parts, and a trapping unit support. The trapping net units are rotatably connected to the trapping unit support via one or more of the rotating parts.
[0009] The rotating part's axis extends along the axial direction of the main rotating shaft or in a direction parallel to the axial direction, allowing the plurality of trapping net units to change the liquid-facing area of the deformable trapping net when rotating around the axis.
[0010] The multiple trapping net units are arranged in a matrix on both sides of the rotating main shaft.
[0011] In at least one possible implementation, the stirring trap comprises two of the aforementioned arc-shaped traps.
[0012] The two curved surface traps are respectively connected to the radial sides of the deformable trap, and the central angle between the inner curved surfaces of the two curved surface traps is less than 180 degrees.
[0013] The two curved traps extend counterclockwise relative to the deformable trap; or, the two curved traps extend clockwise relative to the deformable trap, so that the two curved traps are axially symmetrical with respect to the main axis of rotation.
[0014] In at least one possible implementation, the rotation range of the trapping net unit is limited to one side of the main plane of the trapping net unit support, and this side is the side of the arc-shaped trapping net adjacent to the trapping net unit.
[0015] The rotation range of the plurality of trapping net units on one side of the rotating spindle and the rotation range of the plurality of trapping net units on the other side of the rotating spindle are respectively limited to two opposite sides of the main plane of the trapping unit support.
[0016] In at least one possible implementation, the stirring trap further includes a trap support rod connecting the rotating main shaft and the two arc-shaped trapping nets.
[0017] The angle between the catcher support rod and the deformable catcher net ranges from 60 to 90 degrees.
[0018] In at least one possible implementation, the rotation range of the plurality of trapping net units is limited to the range of 0 to 90 degrees.
[0019] Wherein, 0 degrees corresponds to the main plane of the trapping net unit being parallel to the main plane of the trapping unit support; 90 degrees corresponds to the main plane of the trapping net unit being perpendicular to the main plane of the trapping unit support.
[0020] In at least one possible implementation, the mesh of the trapping net unit is a square hole, the side length of which is 4 to 8 millimeters.
[0021] The deformable trapping net has 4 to 8 rows of trapping net units.
[0022] The deformable trapping net is provided with 4 to 6 rows of trapping net units.

[0028] The stirring trap and stirring trap equipment provided in this application can achieve multiple processing steps such as stirring, trapping, washing and filtering, and preliminary crushing within a single production unit by changing the direction and speed of the stirring trap, thereby reducing the frequency of raw material transfer between multiple processing units. This reduces the risk of microbial growth, foreign matter introduction, and chemical contamination during the transfer process, and improves the production efficiency and product quality of related products.

[0048] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.
[0049] This application provides a stirring trap, which can be installed inside the tank 11 of a stirring trap, such as... Figure 2 , Figure 3 and Figure 4 As shown, the stirring trap 12 may include a deformable trapping net 121, an arc-shaped trapping net 122, and a rotating main shaft 124. The deformable trapping net 121 can extend radially and axially along the tank body 11, and the arc-shaped trapping net 122 can extend circumferentially and axially along the tank body 11. It can be understood that the extension direction here refers to the overall extension direction of either the deformable trapping net 121 or the arc-shaped trapping net 122. That is, the deformable trapping net 121 can be a rectangular trapping net disposed within the tank body 11 and extending axially through the tank body 11, and the arc-shaped trapping net 122 can be a cylindrical trapping net disposed within the tank body 11.
[0050] Preferably, the diameter of the stirring trap 12 can be 798 to 1072 mm.
[0051] like Figure 4As shown, the deformable trapping net 121 may include multiple trapping net units 1211, multiple rotating parts 1212, and a trapping unit support 1213. The trapping net units 1211 can be rotatably connected to the trapping unit support 1213 via one or more rotating parts 1212. In particular, the rotating part 1212 may be provided on a vertical side of the trapping net unit 1211 (with reference to the working posture of the stirring trapping device 12), so that the trapping net unit 1211 can rotate around a vertical support rod of the trapping unit support 1213 (that is, rotate around the axial direction of the tank body 11), thereby changing the liquid-facing area (effective trapping area) of the deformable trapping net 121.
[0052] Preferred, such as Figure 3 and Figure 4 As shown, a trapping net unit 1211 can be rotatably connected to a trapping unit bracket 1213 via multiple rotating parts 1212, making the connection of the trapping net unit 1211 more reliable. The axial spacing between two adjacent rotating parts 1212 can be 120 to 260 mm.
[0053] like Figure 3 and Figure 4 As shown, multiple trapping net units 1211 can be arranged in a matrix on both sides of the rotating main shaft 124. That is, the trapping unit support 1213 can include multiple parallel vertical supports, which can be connected by multiple horizontal supports, and each vertical support can connect multiple trapping net units 1211. Preferably, the spacing (horizontal spacing) between adjacent vertical supports can be 113 to 248 mm.
[0054] Preferably, the mesh size of the trapping net unit 1211 can be square, and the side length of the square mesh can be 4 to 8 millimeters. The number of rows of trapping net units 1211 in the deformable trapping net 121 can be 4 to 8, and the number of columns of trapping net units 1211 in the deformable trapping net 121 can be 4 to 6.
[0055] Furthermore, such as Figure 3 and Figure 4 As shown, the stirring trap 12 may include two arc-shaped trapping nets 122, which can be respectively connected to the radial sides of the deformable trapping net 121. The central angles corresponding to the inner arc surfaces of the two arc-shaped trapping nets 122 can be less than 180 degrees, that is, the two arc-shaped trapping nets 122 will not overlap in the circumferential direction so that a space for material to flow is formed between the two arc-shaped trapping nets 122.
[0056] Furthermore, the circumferential extension directions of the two arc-shaped trapping nets 122 relative to the deformable trapping net 121 are both counterclockwise; or, the circumferential extension directions of the two arc-shaped trapping nets 122 relative to the deformable trapping net 121 are both clockwise. That is, the inner arc surfaces of the two arc-shaped trapping nets 122 face each other, forming an axisymmetric structure centered on the main rotation axis 124. This structure is beneficial for ensuring the trapping effect and improving the rotational stability of the stirring trapping device 12.
[0057] Preferred, such as Figure 2 As shown, the central angle corresponding to the arc-shaped trapping net 122 can be 90 degrees.
[0058] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the rotation range of a trapping net unit 1211 can be limited to one side of the main plane of the trapping net support 1213 (the main plane is the extension surface of the entire trapping net support, such as the rectangular surface when the trapping net support is a rectangular support), and this side can be close to the arc-shaped trapping net 122 adjacent to the trapping net unit 1211. In other words, the rotation range of the trapping net unit 1211 is limited to the inner side of the arc-shaped trapping net 122 adjacent to the trapping net unit 1211.
[0059] Since the two arc-shaped trapping nets 122 are arranged in an axisymmetric manner, the rotation range of the multiple trapping net units 1211 on one side of the rotating main shaft 124 and the rotation range of the multiple trapping net units 1211 on the other side of the rotating main shaft 124 will be respectively limited to the two opposite sides of the main plane of the trapping unit support 1213. It can be understood that when the deformable trapping net 121 rotates about the rotating main shaft 124, the above arrangement can make the liquid-facing angle of each trapping net unit 1211 consistent with or close to that of the arc-shaped trapping net 122, so as to achieve better stirring and trapping effects.
[0060] Preferably, the plurality of trapping net units 1211 can rotate within a range of 0 to 90 degrees from the vertical plane to the parallel plane of the trapping unit support 1213 (here, the trapping net units 1211 can be located on either side of the rotating part 1212 when parallel to the trapping unit support 1213), and rotate only on one side of the trapping unit support 1213. Wherein, 0 degrees corresponds to the trapping net unit 1211 being parallel to the main plane of the trapping unit support 1213; 90 degrees corresponds to the trapping net unit 1211 being perpendicular to the main plane of the trapping unit support 1213. For example, the spacing between the vertical supports of the trapping unit support 1213 can be appropriately smaller than the horizontal width of the trapping net units 1211 (with reference to the working posture of the agitator), so that the vertical supports can restrict the rotation of the trapping net units 1211, specifically restricting the trapping net units to only rotate to a position parallel to the main plane of the trapping unit support, and preventing them from rotating further to the other side of the trapping net support. In another possible embodiment, the rotation range of the trapping net unit 1211 can also be limited by the rotating part 1212 (i.e., using the rotating part 1212 with a rotation angle limitation), and the maximum rotation angle of the rotating part 1212 can be 90 degrees.
[0061] Furthermore, the stirring trap 12 may also include a trap support rod 123, which can connect to the rotating main shaft 124 (or a deformable trap net 121 connected to the rotating main shaft 124) and two arc-shaped trap nets 122. In particular, the trap support rod 123 can connect to the outer ends of the arc-shaped trap nets 122. The trap support rod 123 can enhance the structural stability and load-bearing capacity of the stirring trap. The included angle between the trap support rod 123 and the deformable trap net 121 can be 60 to 90 degrees.
[0062] Based on the structure of the deformable trapping net 121 described above, the deformable trapping net 121 in Figure 2 From the perspective shown, when the deformable trapping net 121 is rotated counterclockwise, under the action of fluid resistance, the trapping net unit 1211 can rotate to a position perpendicular (or nearly perpendicular) to the main plane of the trapping unit support 1213. At this time, as... Figure 4 and Figure 5 As shown, the deformable trapping net 121 has a small liquid-facing area (effective trapping area) and a small trapping capacity for materials (especially micelle materials) (almost no trapping function). In this case, the stirring trapping device 12 mainly undertakes the stirring function.
[0063] exist Figure 2From the perspective shown, if the deformable trapping net 121 is rotated clockwise, it can be understood that, under the conditions of fluid resistance and the aforementioned rotation limit of the trapping net unit 1211, the trapping net unit 1211 can rotate to a position parallel to the main plane of the trapping unit support 1213. At this time, as... Figure 6 As shown, the deformable trapping net 121 has a large liquid-facing area (effective trapping area) and a large material trapping capacity. At this time, the stirring trapping device 12 mainly undertakes the trapping function.
[0064] For example, in Figure 2 From this perspective, when the deformable trapping net 121 is rotated counterclockwise, the stirring trapping device 12 mainly functions to stir the material. When the deformable trapping net 121 is rotated counterclockwise at high speed, the stirring trapping device 12 can also perform preliminary dispersion and cutting of the material (larger particles, micelles). When the deformable trapping net 121 is rotated clockwise, the stirring trapping device 12 mainly functions to trap the material. Furthermore, when the deformable trapping net 121 is rotated clockwise, the arc-shaped trapping net 122 can also perform the function of trapping the material. Therefore, the stirring trapping device 12 provided in this embodiment can achieve multiple functions such as stirring the material, trapping the material, and preliminary dispersion and cutting of the material by adjusting its rotation direction and rotation speed.
[0065] This embodiment also provides a stirring and trapping device, such as... Figure 1 As shown, the stirring and trapping device may include a tank 11, a stirring motor 13, a weighing sensor 14, a breathing cap 15, and the aforementioned stirring trap 12. The stirring trap 12 may be disposed inside the tank 11, and the stirring motor 13 may be disposed outside (upper part) of the tank 11. The stirring motor 13 may be connected to a rotating spindle 124, so that the stirring motor 13 drives the stirring trap 12 (rotating spindle 124) to rotate. In particular, the output shaft rotation direction of the stirring motor 13 in this application can be changed at different production stages (the rotation direction of the rotating spindle 124 connected to the stirring motor 13 will naturally change accordingly), that is, the rotation direction of the stirring trap 12 can be changed. For example, in the production process of sodium caseinate, acid precipitation, trapping, and crushing processes can be carried out sequentially in the stirring and trapping device, and the rotation direction of the stirring motor 13 can be changed with the switching of the processing process. For example (using Figure 2 Taking the perspective of the process as an example, in the acid precipitation step, the stirring trap 12 can rotate counterclockwise; in the trapping step, the stirring trap 12 can rotate clockwise; in the crushing step, the stirring trap 12 can rotate counterclockwise (for a detailed description of each step, please refer to the workflow described later).
[0066] Preferably, the effective volume of the stirring and trapping device can be 3,000 to 5,000 liters.
[0067] Preferably, the stirring motor 13 can be a variable frequency motor with a maximum rated power of 80 to 150 kilowatts.
[0068] The acid settling tank in the sodium caseinate production process is used as an example of the stirred collection device in this embodiment. A possible workflow of this stirred collection device is briefly described (using...). Figure 2 (From the perspective of [the person in question], for example):
[0069] Acid precipitation step: The casein solution formed by mixing in a mixer can enter a stirred trap device. An acid tank can be connected to the stirred trap device to add a dilute hydrochloric acid solution (food grade) to the casein solution. Preferably, after the casein solution enters the stirred trap device, the temperature inside the device can be maintained at 40 to 55 degrees Celsius, and food-grade dilute hydrochloric acid is slowly added until the pH of the casein solution stabilizes at 4.1 to 4.6.
[0070] During the above process, the stirring trap 12 can be continuously rotated counterclockwise at a medium speed. When the precipitated casein particles gradually aggregate and increase in size to form casein micelles, the stirring trap 12 can be adjusted to rotate counterclockwise at a low speed until the casein micelles are completely formed, and the acid precipitation step ends.
[0071] Collection Steps: After the acid precipitation step, the stirring trap 12 can be adjusted to rotate clockwise at high speed. Each trap unit 1211 in the deformable trap 121 can rotate 90 degrees counterclockwise under the action of resistance through the rotating part 1212 until it coincides with or is parallel to the trap unit support 1213. The curved trap 122 and the deformable trap 121 form a complete casein micelle precipitation trapping system. The casein micelle precipitation will be intercepted by the stirring trap 12 under the action of centrifugal force and gradually form a filter layer. The trapping process ends after a certain period of time, completing one trapping of casein micelle precipitation.
[0072] Crushing Step: After the casein micelles are collected and precipitated, the rotation speed of the stirring collector 12 can be maintained at a constant speed while the clear liquid in the stirring collector is discharged. After the clear liquid is drained, RO water (deionized water) can be added to the stirring collector to the set level. The stirring collector 12 can be adjusted to rotate counterclockwise at high speed. The casein micelles can be dispersed and cut by the stirring collector 12 (especially the collection unit support 1213), and evenly dispersed in the material system.
[0073] Preferably, after the above acid precipitation step is completed, the collection step can be performed multiple times (in particular, three collection steps can be performed), and the acid precipitation tank can be washed and filtered between each collection step (that is, the clear liquid in the acid precipitation tank is drained and then deionized water is added).
