[0028] Embodiment 1

[0029] Embodiment 1 of the present application provides a whipping device, such as Figures 1 to 3 As shown, the whipping device comprises:

[0030] Booster pump 100;

[0031] The spiral empty tube 200 is connected to the booster pump 100. The booster pump 100 pumps the raw material into the spiral empty tube 200. At least part of the spiral empty tube 200 extends in a spiral shape.

[0032] like Figure 1 As shown, in this embodiment, it is exemplarily explained that this embodiment takes the whipping device to mix and whip milk slurry or milk liquid and air to prepare milk cap as an example. When the booster pump 100 is working, the milk slurry or milk liquid and air pass through the booster pump 100, and the booster pump 100 can demulsify the milk slurry or milk liquid, and at the same time, preliminarily mix and whip the milk slurry or milk liquid with air. Then the booster pump 100 further pumps the demulsified milk slurry or milk liquid and air to the spiral empty tube 200. Due to the spiral setting of the spiral empty tube 200, the milk slurry or milk liquid and air can be further mixed and whipped in the spiral empty tube 200 by centrifugal force. At the same time, due to the spiral setting of the spiral empty tube 200, the spiral empty tube 200 has a relatively long length in a relatively limited space, so that the milk slurry or milk liquid and air have a longer whipping path, which is conducive to the milk slurry or milk liquid and air to form a high-speed mixing, deceleration and steady flow and defoaming whipping process, so as to ensure a better whipping effect.

[0033] Of course, in some embodiments, the whipping device can also mix and whip other raw materials to prepare milk cap. Alternatively, the whipping device can also mix and whip raw materials to prepare other foamed products, such as the whipping device is used to prepare cream, which is not specifically limited here.

[0034] It can be understood that the present application can demulsify the milk slurry or milk liquid through the booster pump 100, and can preliminarily mix and whip the milk slurry or milk liquid and air; and then through the spiral empty tube 200, the demulsified milk slurry or milk liquid and air can be further mixed and whipped. At the same time, since the further mixing and whipping process has a relatively long whipping path due to the spiral setting of the spiral empty tube 200, an effective whipping process can be completed. Therefore, the present application does not need to rely on complex structural components such as whipping discs or stirring blades to ensure the whipping effect of the milk cap, which can reduce the difficulty and cost of preparing the whipping device.

[0035] At the same time, it is not difficult to understand that since the spiral empty tube 200 in the present application has a relatively simple structure compared to components such as beating discs or stirring blades, the present application also has the advantages of easy cleaning, no dead corners during cleaning, and low manufacturing cost.

[0036] Specifically, the spiral hollow tube 200 extends in a spiral shape as a whole, and the spiral line when extended is a cylindrical spiral line, a conical spiral line or an arc spiral line with a three-dimensional distribution.

[0037] like Figure 1As shown, in this embodiment, it is exemplarily explained that the spiral empty tube 200 can be distributed in a three-dimensional space, and the whole is extended in a spiral shape. The spiral line of the spiral empty tube 200 when extending can be a cylindrical spiral line, a conical spiral line or a circular arc spiral line. When the spiral line of the spiral empty tube 200 when extending is a cylindrical spiral line, the radius of the milk slurry or milk and air when mixing and whipping by centrifugal force remains unchanged. When the spiral line of the spiral empty tube 200 when extending is a conical spiral line, the radius of the milk slurry or milk and air when mixing and whipping by centrifugal force gradually decreases or increases, which depends on how the inlet and outlet of the spiral empty tube 200 are selected and arranged, which will not be repeated here. When the spiral line of the spiral empty tube 200 when extending is a circular arc spiral line, the radius of the milk slurry or milk and air when mixing and whipping by centrifugal force decreases and then increases. This embodiment takes the spiral line of the spiral empty tube 200 when extending as a cylindrical spiral line as an example.

[0038] Of course, in some embodiments, the spiral tube 200 may be only partially extended in a spiral shape in three-dimensional space, while the rest may be extended in a straight line, etc. However, it should be noted that the longer the spiral tube 200 is when it is extended in a spiral shape and the shorter the length is when it is extended in a straight line, the easier it is to obtain a better whipping effect.

[0039] It can be understood that this embodiment reasonably arranges the spiral line of the spiral empty tube 200 when it is extended in a three-dimensional space, which is beneficial to further mixing and whipping the milk paste or milk liquid and air in the spiral empty tube 200 by using centrifugal force, thereby ensuring the whipping effect.

[0040] Specifically, at least one end of the spiral empty pipe 200 close to the booster pump 100 extends in a spiral shape and is set as an empty pipe inlet. The raw material enters the spiral empty pipe 200 from the empty pipe inlet, and the direction in which the raw material enters the spiral empty pipe 200 is tangent to the spiral line of the spiral empty pipe 200 when it is spirally extended.

[0041] like Figure 1 As shown, in this embodiment, it is exemplarily explained that the spiral empty tube 200 can be extended in a spiral line as a whole, or can be extended in a spiral line only at one end close to the boost pump 100, and can be extended in a straight line at one end away from the boost pump 100. This embodiment takes the former as an example, and the spiral line of the spiral empty tube 200 when it is spirally extended can be a cylindrical spiral line. The empty tube inlet of the spiral empty tube 200 can be connected to the boost pump 100 through an intermediate pipeline, the intermediate pipeline can be extended in a straight line, and the axis of the intermediate pipeline when it is extended can be tangent to the spiral line of the spiral empty tube 200 when it is spirally extended, so as to achieve the purpose of making the direction of milk slurry or milk and air entering the spiral empty tube 200 tangent to the spiral line of the spiral empty tube 200 when it is spirally extended.

[0042] It can be understood that, by reasonably setting the direction in which milk slurry or milk liquid and air enter the spiral empty tube 200, this embodiment can maintain the kinetic energy of the milk slurry or milk liquid and air when they enter the spiral empty tube 200, thereby facilitating the mixing and whipping of the milk slurry or milk liquid and air in the spiral empty tube 200 using centrifugal force.

[0043] Specifically, the boost pump 100 is a gear pump.

[0044] In this embodiment, the booster pump 100 can be preferably a gear pump. Compared with other forms of booster pumps 100, the gear pump can relatively effectively demulsify the milk or milk slurry when pumping the milk or milk slurry and air into the spiral hollow tube 200. The gear pump can be an external gear pump or an internal gear pump.

[0045] It can be understood that, in this embodiment, by configuring the booster pump 100 as a gear pump, the demulsification effect on milk or milk slurry can be ensured.

[0046] Specifically, the booster pump 100 includes a pump body 110 and a pair of mutually cooperating impellers, the pair of mutually cooperating impellers are arranged in the pump body 110, the pump body 110 is provided with a pump body inlet 111 and a pump body outlet 112, the pump body inlet 111 and the pump body outlet 112 are distributed on both sides of the pair of mutually cooperating impellers, the raw material enters the pump body 110 from the pump body inlet 111, and after passing through the pair of mutually cooperating impellers, it is discharged from the pump body 110 from the pump body outlet 112.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, it is exemplarily explained that when the boost pump 100 is a gear pump, it can be an external gear pump. At this time, the boost pump 100 can include a pair of mutually matched runners, and the runner can be a gear, that is, a pair of mutually matched runners can be a driving tooth 120 and a driven tooth 130. The driving tooth 120 can be transmitted with the output end of a motor or other components, and the driven tooth 130 can be meshed with the driving tooth 120. The line connecting the center points of the driving tooth 120 and the driven tooth 130 can intersect with the line connecting the pump body inlet 111 and the pump body outlet 112, so that the pump body inlet 111 and the pump body outlet 112 are distributed on both sides of a pair of mutually matched runners. When the output end of the motor rotates, the output end of the motor can drive the driving tooth 120 to rotate synchronously, and when the driving tooth 120 rotates, it can drive the driven tooth 130 to rotate synchronously. On the side where the pump body inlet 111 is located, the teeth of a pair of mutually matched wheels are separated from each other to form a low pressure, so as to pump the milk slurry or milk liquid and air into the pump body 110 from the pump body inlet 111. On the side where the pump body outlet 112 is located, the teeth of a pair of mutually matched wheels are closed together to form a high pressure, so as to pump the milk slurry or milk liquid and air out of the pump body 110 from the pump body outlet 112.

[0048] like Figure 3 As shown, of course, in some embodiments, the runner may also be an impeller, that is, a pair of mutually cooperating runners may be an active impeller and a driven impeller. The active impeller and the driven impeller may specifically include a plurality of blades arranged at equal intervals along the circumferential direction, and the active impeller and the driven impeller may be driven by their blades to cooperate with each other.

[0049] It can be understood that, by reasonably arranging the positions of the pump body inlet 111, the pump body outlet 112 and the pair of cooperating wheels, the booster pump 100 can ensure the demulsification effect of the pair of cooperating wheels on the milk slurry or milk liquid before pumping the milk slurry or milk liquid and air into the spiral empty tube 200, and can also improve the effect of the booster pump 100 on the preliminary mixing and whipping of the milk slurry or milk liquid and the air pump.

[0050] The implementation principle of a whipping device provided in the first embodiment of the present application is as follows:

[0051] When the milk cap is whipped, the booster pump 100 works, and a pair of mutually coordinated rotating wheels pump milk slurry or milk and air into the pump body 110 from the pump body inlet 111, and pump the milk slurry or milk and air out of the pump body 110 from the pump body outlet 112, and pump them into the spiral empty tube 200. When the milk slurry or milk and air pass through a pair of mutually coordinated rotating wheels, the pair of mutually coordinated rotating wheels can demulsify the milk slurry or milk, and at the same time, the milk slurry or milk and air can be preliminarily mixed and whipped. Subsequently, the booster pump 100 further pumps the demulsified milk slurry or milk and air into the spiral empty tube 200. Due to the spiral setting of the spiral empty tube 200, the milk slurry or milk and air can be further mixed and whipped in the spiral empty tube 200 by centrifugal force.

[0052] The present application can demulsify milk slurry or milk liquid through the booster pump 100, and can preliminarily mix and whip the milk slurry or milk liquid and air; and then the demulsified milk slurry or milk liquid and air can be further mixed and whipped through the spiral empty tube 200. At the same time, since the further mixing and whipping process has a relatively long whipping path due to the spiral setting of the spiral empty tube 200, an effective whipping process can be completed. Therefore, the present application does not need to rely on complex structural components such as whipping discs or stirring blades to ensure the whipping effect of the milk cap, which can reduce the difficulty and cost of preparing the whipping device.

[0053] Embodiment 2

[0054] Embodiment 2 of the present application provides a whipping device, and the difference between this embodiment and embodiment 1 is at least in: the shape of the spiral empty tube 200.

[0055] Specifically, the spiral empty tube 200 extends in a spiral shape as a whole, and the spiral line when extended is a two-dimensionally distributed constant-speed spiral line or an equiangular spiral line.

[0056] like Figure 4 As shown, in this embodiment, it is exemplarily explained that the spiral empty tube 200 can also be distributed in a two-dimensional space, and the whole is extended in a spiral shape, and the spiral line of the spiral empty tube 200 when extending can be a constant speed spiral line or an equiangular spiral line. In this embodiment, the spiral line of the spiral empty tube 200 when extending is an example of a constant speed spiral line. At this time, the orientation of the inlet and outlet of the spiral empty tube 200 can be perpendicular to the phase plane where the spiral line of the spiral empty tube 200 is when extending, so that the spiral empty tube 200 is connected to the booster pump 100. Similarly, the inlet of the spiral empty tube 200 can be detachably provided with an intermediate pipeline connected to the booster pump 100, or it can be integrated with the intermediate pipeline. The outlet of the spiral empty tube 200 is set in the same way.

[0057] In some embodiments, the spiral empty tube 200 can also be a combination of three-dimensional distribution and three-dimensional distribution, two-dimensional distribution and two-dimensional distribution, or three-dimensional distribution and two-dimensional distribution. For example, when the spiral empty tube 200 is extended, the axis first extends in a cylindrical spiral line shape, and then extends in a uniform speed spiral line shape.

[0058] It can be understood that this embodiment reasonably arranges the spiral line of the spiral empty tube 200 when it is extended in a two-dimensional space, which is also beneficial for the milk paste or milk liquid and air to be further mixed and whipped by centrifugal force in the spiral empty tube 200, thereby ensuring the whipping effect.

[0059] The implementation principle of the second embodiment of the present application is basically the same as that of the first embodiment.

[0060] Embodiment 3

[0061] Embodiment 3 of the present application provides a whipping device, and the difference between this embodiment and embodiment 1 is at least in: the shape of the spiral empty tube 200.

[0062] Specifically, the spiral empty tube 200 is distributed in two dimensions, and part of the spiral empty tube 200 extends in a spiral shape, and part of the spiral empty tube 200 extends in a straight line. The part of the spiral empty tube 200 extending in a spiral shape and the part extending in a straight line are alternately arranged.

[0063] like Figure 5 As shown, in this embodiment, for illustrative purposes, the spiral empty tube 200 may also be only partially extended in a spiral shape, and the portion extending in a spiral shape may be intermittently arranged and connected by the portion extending in a straight line.

[0064] It can be understood that, by configuring the spiral empty tube 200 to extend partially in a spiral shape and partially in a straight line, this embodiment can, to a certain extent, still ensure that the milk slurry or milk liquid and air are further mixed and whipped in the spiral empty tube 200 using centrifugal force.

[0065] More specifically, when the spiral empty tube 200 extends in a straight line, the extending direction includes a first direction and a second direction, and the second direction intersects with the first direction.

[0066] like Figure 5 As shown, in this embodiment, it is exemplified that the extension directions of the parts extending in a straight line on both sides of the part extending in a spiral line of the spiral empty tube 200 can be the first direction and the second direction respectively; at the same time, the first direction and the second direction can be perpendicular to each other. For example, when the spiral empty tube 200 is extended, it can be folded or spread in a rectangular shape, that is, the spiral empty tube 200 can first extend in the positive direction of the first direction, then extend in the positive direction of the second direction, then extend in the reverse direction of the first direction, and then extend in the reverse direction of the second direction, and so on. At this time, one of the first direction and the second direction constitutes the length direction of the rectangular-like structure, and the other constitutes the width direction of the rectangular-like structure. The parts extending in a spiral line of the spiral empty tube 200 are sequentially arranged between the two adjacent parts extending in a straight line, and the parts extending in a spiral line of the spiral empty tube 200 constitute the connection between the adjacent two sides of the rectangular-like structure.

[0067] Of course, in some embodiments, the first direction and the second direction may also be at other intersecting angles.

[0068] In other embodiments, the spiral hollow tube 200 may extend in the first direction or the second direction only when extending in a straight line, and it may also be gathered or spread in a rectangular shape when extending. For example, the spiral hollow tube 200 may extend in the positive direction of the first direction first, and then extend in the reverse direction of the first direction, and so on. The portion of the spiral hollow tube 200 extending in a helical line may be arranged between two adjacent portions extending in a straight line, and the portion of the spiral hollow tube 200 extending in a helical line constitutes two sides of the length direction or two sides of the width direction of the rectangular structure.

[0069] More specifically, the spiral line of the spiral empty tube 200 when extended is in an "S" shape.

[0070] like Figure 6As shown, in this embodiment, it is exemplarily explained that when the extension direction of the portion of the spiral empty tube 200 extending in a straight line can be the first direction and the second direction respectively, the spiral empty tube 200 can also be first extended in the positive direction of the first direction, then extended in the positive direction of the second direction, then extended in the reverse direction of the first direction, and then extended in the positive direction of the second direction, and so on, and similarly, the portion of the spiral empty tube 200 extending in a helical line connects two adjacent portions extending in a straight line. At this time, the spiral empty tube 200 extends in an "S" shape.

[0071] Of course, in some embodiments, the first direction and the second direction can be interchanged, and both can also make the spiral hollow tube 200 extend in an "S" shape.

[0072] The implementation principle of the third embodiment of the present application is basically the same as that of the first embodiment.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
