Description

Technical Field

[0001] The utility model relates to the technical field of frozen food preparation, in particular to an ice cream production mixing device. Background Art

[0002] Ice cream is a frozen food made from dairy products as the main raw material, with drinking water, sucrose, fruit products, soy products and other auxiliary materials added, and is made through processes such as mixing, homogenization, aging, molding, and freezing. In the mixing stage, in order to achieve the mixing of the raw materials, the raw materials are usually placed in a mixing tank and stirred by a stirring rod in the mixing tank to achieve the fusion of the raw materials.

[0003] Since the dairy products and soy products in the raw materials are usually powdered and easy to float or suspend in drinking water, and sucrose is a hard particle that is easy to precipitate, the raw materials will be stratified in the mixing tank. At the same time, different raw materials have different dissolution rates, and it often takes a long time for the raw materials to be mixed. Therefore, there is an urgent need for an ice cream production mixing device that can accelerate the fusion of raw materials. Utility Model Content

[0004] The utility model aims to provide an ice cream production mixing device to solve the technical problem of slow layering and fusion speed of ice cream raw materials in the prior art.

[0005] The utility model provides the following basic solutions:

[0006] An ice cream production mixing device comprises a mixing cylinder. A stirring shaft is arranged in the mixing cylinder. The stirring shaft is vertically arranged and provided with stirring blades. There are multiple stirring shafts, and the distances from the stirring blades on the multiple stirring shafts to the bottom of the mixing cylinder are different.

[0007] Beneficial effects of the basic program:

[0008] Multiple stirring shafts are used to stir and mix different areas in the mixing tank. At the same time, the distances from the stirring blades to the bottom of the mixing tank are different, that is, the stirring blades are located at different heights in the liquid raw materials. When stirring, the stirring blades stir and mix the raw materials layered at different heights, so that the layered raw materials merge with each other. By accelerating the fusion of the raw materials layered at different heights, the overall fusion speed of the raw materials is improved.

[0009] Compared with the existing scheme in which the stirring blades are located at the same height, the adoption of this scheme can speed up the fusion of the layered ice cream ingredients, thereby improving the production efficiency of ice cream.

[0010] Furthermore, the stirring blade is sleeved on the stirring shaft, and a blocking member is provided between the stirring blade and the stirring shaft. The blocking member is used to block the movement of the stirring blade on the stirring shaft. Beneficial effect: With this design, the height of the stirring blade in the mixing cylinder can be adjusted as needed. When the amount of ice cream raw materials to be mixed this time is small, the stirring blade is moved downward and positioned by the blocking member, so that each stirring blade can stir the ice cream raw materials, avoiding the idling of the stirring blade and wasting production resources.

[0011] Furthermore, the blocking member includes a first protrusion and a second protrusion that can be hooked. The first protrusion and the second protrusion are respectively provided on the stirring shaft and the stirring blade. Beneficial effect: With this design, the movement and positioning of the stirring blade are realized through a simple structure.

[0012] Furthermore, the first protrusion is provided on the peripheral wall of the stirring shaft; the second protrusion is provided on the stirring blade. The second protrusion includes a second transverse protrusion and a second longitudinal protrusion. The top end of the second longitudinal protrusion is connected to the second transverse protrusion, and the second protrusion can be hooked on the first protrusion. Beneficial effect: The second protrusion can be designed as a T shape, an inverted L shape, a "冂" shape, etc. When moving the stirring blade, rotate the stirring blade around the stirring shaft until the second protrusion and the first protrusion are separated. At this time, the stirring blade can be moved along the axial direction of the stirring shaft. When the stirring blade moves to the designated position, rotate the stirring blade so that the second protrusion is hooked on another first protrusion on the stirring shaft to realize the positioning of the stirring blade. When the stirring shaft rotates, the first protrusion drives the second protrusion, so that the rotating blade rotates with the stirring shaft, thereby stirring the ice cream raw materials at a specified height and making the ice cream raw materials blend more evenly and fully.

[0013] Furthermore, the first protrusion is a cylinder, and the axial direction of the first protrusion is perpendicular to the axial direction of the stirring shaft; or, the first protrusion includes a first transverse protrusion and a first longitudinal protrusion, and the bottom end of the first longitudinal protrusion is connected to the first transverse protrusion. Beneficial effect: The first protrusion can be designed as a protruding cylinder, which is convenient for hooking the second protrusion. At the same time, the first protrusion can also be designed as an L shape that cooperates with the second protrusion, etc. The first protrusion is designed in different shapes according to needs.

[0014] Furthermore, the number of the first protrusions is multiple, and the first protrusions are evenly distributed on the peripheral wall of the stirring shaft, and the first protrusions at different heights are arranged staggeredly. Beneficial effect: Multiple first protrusions can position the stirring blade at different heights for stirring ice cream raw materials with different dosages. At the same time, the first protrusions at different heights are arranged staggeredly, which can block the downward movement of the stirring blade when moving the stirring blade, avoiding the stirring blade from directly sliding to the free end of the stirring shaft.

[0015] Furthermore, a blocking portion is provided at the free end of the stirring shaft to prevent the stirring blade from disengaging from the stirring shaft. Beneficial effect: With this design, the stirring blade is prevented from disengaging from the free end of the stirring rod. Description of the Drawings

The stirring shaft 2 is keyed to the output shaft of the motor, so that the stirring shaft 2 extends from the top of the mixing tank 1 to the bottom.

[0024] As attached Figure 2 As shown, the stirring shaft 2 is provided with a stirring blade 3, and the number of the stirring shafts 2 is multiple. In the present embodiment, the number of the stirring shafts 2 is two, one stirring shaft 2 is provided with a stirring blade 3, and the other stirring shaft 2 is provided with two stirring blades 3, and the stirring blades 3 are key-connected to the stirring shaft 2.

[0025] The distances between the stirring blades 3 on the multiple stirring shafts 2 and the bottom of the mixing tank 1 are different. Specifically, the distances between the three stirring blades 3 and the bottom of the mixing tank 1 are A, B, and C, respectively, and A≠B≠C.

[0026] With this solution, when the stirring blades 3 at different heights rotate, the layered raw materials are fused together, and the fusion speed of the raw materials as a whole is increased by accelerating the fusion of the layers at different heights. Compared with the existing stirring blades 3 at the same height, the fusion of the layered ice cream raw materials can be accelerated, thereby improving the production efficiency of ice cream.

[0027] Embodiment 2

[0028] The difference between this embodiment and the first embodiment is that:

[0029] An ice cream production mixing device, wherein the stirring blade 3 is not connected to the stirring shaft 2 by a key. Specifically:

[0030] As attached Figure 3 , Attachment Figure 4 As shown, the stirring blade 3 is sleeved on the stirring shaft 2, and a blocking member is provided between the stirring blade 3 and the stirring shaft 2, and the blocking member is used to block the movement of the stirring blade 3 on the stirring shaft 2. The free end of the stirring shaft 2 is provided with a blocking portion 4 for preventing the stirring blade 3 from escaping from the stirring shaft 2. In this embodiment, the bottom end of the stirring shaft 2 extends circumferentially to form the blocking portion 4.

[0031] The blocking member includes a first protrusion 5 and a second protrusion 6 that can be hooked, and the first protrusion 5 and the second protrusion 6 are respectively arranged on the stirring shaft 2 and the stirring blade 3. In this embodiment, the first protrusion 5 is arranged on the peripheral wall of the stirring shaft 2, and the second protrusion 6 is arranged on the stirring blade 3.

[0032] The first protrusion 5 is a cylinder, and the axial direction of the first protrusion 5 is perpendicular to the axial direction of the stirring shaft 2, or the first protrusion 5 includes a first transverse protrusion and a first longitudinal protrusion, the bottom end of the first longitudinal protrusion is connected to the first transverse protrusion, and the side walls of the first transverse protrusion and the first longitudinal protrusion are both connected to the peripheral wall of the stirring shaft 2.

[0033] The second protrusion 6 includes a second transverse protrusion and a second longitudinal protrusion, the top end of the second longitudinal protrusion is connected to the second transverse protrusion, the second protrusion 6 can be hung on the first protrusion 5, and the side walls of the second transverse protrusion and the second longitudinal protrusion are connected to the inner circumferential wall of the stirring blade 3.

[0034] Specifically, the design of the first protrusion 5 and the second protrusion 6 includes the following solutions:

[0035] Solution 1: The first protrusion 5 is a cylinder, and the second protrusion 6 includes a second transverse protrusion and a second longitudinal protrusion. The top of the second longitudinal protrusion is connected to the end of the second transverse protrusion. The connection between the second longitudinal protrusion and the second transverse protrusion has an angle. When positioning the stirring blade 3, the first protrusion 5 is located at the angle. At this time, the second protrusion 6 is blocked by the first protrusion 5, and the stirring blade 3 cannot move down, thereby achieving the positioning of the stirring blade 3. The end connected to the second longitudinal protrusion is associated with the rotation direction of the stirring shaft 2, and the end is the end of the rotation direction of the stirring shaft 2 (when the rotating shaft rotates, the end after the first protrusion 5 is the end), so that the first protrusion 5 can push the second protrusion 6 to rotate. Among them, the second transverse protrusion and the second longitudinal protrusion are integrally formed.

[0036] Solution 2: The first protrusion 5 is a cylinder, and the second protrusion 6 includes a second transverse protrusion and a second longitudinal protrusion. The top of the second longitudinal protrusion is connected to the center of the bottom surface of the second transverse protrusion, and the second longitudinal protrusion and the second transverse protrusion are inverted T-shaped. At this time, the connection between the second longitudinal protrusion and the second transverse protrusion is at two angles. When positioning the stirring blade 3, the angle at which the first protrusion 5 is located is associated with the rotation direction of the stirring shaft 2. When the rotating shaft rotates, the angle that the first protrusion 5 passes first is the angle at which the first protrusion 5 is located when positioning. Among them, the second transverse protrusion and the second longitudinal protrusion are integrally formed.

[0037] Solution 3: The first protrusion 5 includes a first transverse protrusion and a first longitudinal protrusion, and the second protrusion 6 includes a second transverse protrusion and a second longitudinal protrusion. The end of the first transverse protrusion connected to the first longitudinal protrusion is associated with the rotation direction of the stirring shaft 2, and the end is the head end of the rotation direction of the stirring shaft 2. Correspondingly, the end of the second longitudinal protrusion connected to the second transverse protrusion is the end end of the rotation direction of the stirring shaft 2. Among them, the first transverse protrusion and the first longitudinal protrusion are integrally formed, and the second transverse protrusion and the second longitudinal protrusion are integrally formed.

[0038] In this embodiment, the first protrusion 5 and the second protrusion 6 adopt the design of scheme one, the first protrusion 5 is integrally formed with the stirring shaft 2, the stirring blade 3 includes an annular blade sleeve 7, and a blade 8 connected to the outer wall of the blade sleeve 7, the second protrusion 6 is located on the inner wall of the blade sleeve 7, and the second protrusion 6, the blade sleeve 7 and the blade 8 are integrally formed.

[0039] There are multiple first protrusions 5, which are evenly distributed on the peripheral wall of the stirring shaft 2, and the first protrusions 5 at different heights are arranged in a staggered manner. In this embodiment, there are nine first protrusions 5, which are divided into three rows, with three protrusions in each row. The first protrusions 5 in the same row are at the same height and are equidistantly distributed, and the first protrusions 5 in different rows are at different heights, and the first protrusions 5 in different rows are arranged in a staggered manner. The corresponding number of second protrusions 6 is three, and the position of the second protrusions 6 is opposite to the position of the first protrusions 5 in the same row on the stirring shaft 2, and they are used in conjunction with each other.

[0040] By adopting this solution, the height of the stirring blade 3 in the mixing tank 1 can be adjusted as needed. When the amount of ice cream raw materials mixed this time is small, the stirring blade 3 is moved down and positioned by a blocking member so that each stirring blade 3 can stir the ice cream raw materials, thereby avoiding idling of the stirring blade 3 and wasting production resources, thereby avoiding waste of ice cream production costs.

[0041] The above is only an embodiment of the utility model. The common sense such as the known specific structure and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field know all the common technical knowledge in the technical field of the utility model before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date.
