Description

Technical Field

[0001] This application relates to the technical field of cream mixing, and in particular to an electric mixing mechanism for cream production. Background Technology

[0002] Cream is a dairy product made by centrifuging milk to obtain light cream, which is then matured, churned, and pressed. Cream is primarily composed of milk fat, is rich in nutrients, and can be eaten directly or used as an ingredient in other foods such as ice cream. Cream is indispensable in the processing and production of pastries; the churning and preparation of cream is an essential step.

[0003] Chinese patent application number CN202320706831.5 discloses an electric stirring mechanism for cream production. It includes a base plate, a stirring tank on the upper right side of the base plate, a fixing block fixedly connected to the left side of the upper surface of the base plate, a clamping structure on the right side of the fixing block, a fixing plate fixedly connected to the upper surface of the fixing block, a movable plate inside the fixing plate, a rack fixedly connected to the front of the movable plate, a support plate fixedly connected to the left side of the fixing plate, a forward and reverse motor fixedly connected to the upper surface of the support plate, and a gear fixedly connected to the right end of the rotating shaft. This application improves upon the problem that both the first and second stirring blades rotate simultaneously under the drive of the forward and reverse motors in the same direction, resulting in poor stirring effect on the cream. Furthermore, the second stirring blade is fixedly located at the bottom of the stirring tank, making it difficult to remove the cream from the tank and inconvenient to use.

[0004] The aforementioned technologies have the following drawbacks: When the electric stirring mechanism for cream production stirs the cream, it relies solely on traditional stirring components for stirring operations. However, the simple stirring components generally have a poor stirring effect per unit time and are prone to forming dead zones at the bottom and corners of the stirring drum, thereby affecting the stirring effect of the cream. Utility Model Content

[0005] In order to improve the problem that the mixing effect of the mixing component is generally poor per unit time and that dead zones are easily formed at the bottom and corners of the mixing drum, thereby affecting the mixing effect of cream, this application provides an electric mixing mechanism for cream production.

[0006] The electric stirring mechanism for cream production provided in this application adopts the following technical solution:

[0007] An electric stirring mechanism for cream production includes a base, a stirring drum, a stirring shaft, and a stirring motor. The stirring motor's output end is coaxially fixed to a drive gear; one end of the stirring shaft extending from the base is coaxially fixed to a transmission gear meshing with the drive gear; the stirring shaft has multiple stirring paddles spaced apart along its length, each paddle comprising two opposing stirring blades; the stirring shaft has multiple radially penetrating grooves along its axial direction; the stirring paddles are slidably disposed in the grooves; a cavity is provided within the stirring shaft to connect the grooves; a sliding rod is vertically mounted within the cavity along the length of the stirring shaft; a connecting rod penetrating the groove is fixed between the sliding rod and the stirring paddles; and a lifting assembly is provided at the upper end of the stirring shaft to drive the sliding rod to reciprocate within the cavity as the stirring shaft rotates.

[0008] Furthermore, the lifting assembly includes a cylindrical cam, one end of which is coaxially fixed to the slide rod. A positioning cylinder is provided on the base and sleeved outside the cylindrical cam. A slide head that is adapted to slide along the spiral groove on the cylindrical cam is fixed to the inner peripheral wall of the positioning cylinder.

[0009] Furthermore, an elastic element connects the slide rod and the slide head.

[0010] Furthermore, a flexible cover is fitted onto the connecting rod, with one end of the flexible cover fixed to the connecting rod and the other end fixed to the stirring shaft, thus shielding the chute.

[0011] Furthermore, at least two of the stirring blades are arranged on opposite sides of the stirring shaft, with the two stirring blades on opposite sides having staggered inclination angles.

[0012] Furthermore, the stirring blade has several through holes that penetrate the stirring blade.

[0013] In summary, the beneficial technical effects of this application are as follows:

[0014] When churning butter, the rotating mixing shaft drives the mixing blades to rotate as well. Simultaneously, under the action of the lifting assembly, the sliding rod reciprocates up and down along the length of the mixing shaft within the cavity located in the shaft's cavity, causing the mixing blades to move up and down simultaneously. This helps break up laminar flow in the butter, promoting turbulence and thus improving mixing efficiency. It also pushes butter from the bottom of the mixing bowl to the top, and vice versa, effectively reducing dead zones in the mixing bowl. This improves the quality and texture of the butter while also significantly accelerating the production process and increasing production efficiency. Attached Figure Description

[0019] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application discloses an electric stirring mechanism for cream production. (See also...) Figure 1 and Figure 3 An electric stirring mechanism for cream production includes a base 1, a stirring drum 2, a stirring shaft 3, and a stirring motor 4. A drive gear 41 is coaxially fixed to the output end of the stirring motor 4. A transmission gear 34, meshing with the drive gear 41, is coaxially fixed to one end of the stirring shaft 3 extending from the base 1. The stirring shaft 3 is provided with multiple stirring blades spaced apart along its length. Each stirring blade includes two opposing stirring blades 31. The stirring shaft 3 is provided with multiple radially penetrating grooves 32. The chute 32 is arranged along the axial direction of the stirring shaft 3. Multiple stirring paddles are slidably arranged in the multiple chute 32. The stirring shaft 3 is provided with a cavity 33 for connecting the multiple chute 32. A slide rod 331 is arranged in the cavity 33 along the length direction of the stirring shaft 3. A connecting rod 332 that passes through the chute 32 is fixed between the slide rod 331 and the stirring paddle. A lifting component is provided at the upper end of the stirring shaft 3 for driving the slide rod 331 to reciprocate in the cavity 33 as the stirring shaft 3 rotates.

[0021] When the cream is being churned, the rotating mixing shaft 3 drives the mixing blades 31 to rotate accordingly. Simultaneously, under the action of the lifting assembly, the sliding rod 331 reciprocates up and down along the length of the mixing shaft 3 within the cavity 33 located in the mixing shaft 3, causing the mixing blades 31 to reciprocate up and down while rotating. This helps break up the laminar flow in the cream, promoting turbulence and thus improving mixing efficiency. It also pushes the cream from the bottom of the mixing drum 2 to the top, and vice versa, effectively reducing dead zones in the mixing drum 2. This improves the quality and taste of the cream while also effectively accelerating the cream production process and increasing production efficiency.

[0022] Specific references Figure 1 and Figure 3 The lifting assembly includes a cylindrical cam 5, one end of which is coaxially fixed to a slide rod 331. A positioning cylinder 51 is fixedly attached to the base 1 and sleeved outside the cylindrical cam 5. A slide head 52, which is adapted to slide along the spiral groove on the cylindrical cam 5, is fixedly attached to the inner circumferential wall of the positioning cylinder 51.

[0023] When the stirring shaft 3 rotates, it drives the cylindrical cam 5, which is coaxially fixed to it, to rotate. The spiral groove on the cylindrical cam 5 cooperates with the slide head 52 on the inner wall of the positioning cylinder 51, so that the cylindrical cam 5 moves up or down while rotating with the stirring shaft 3. This causes the slide rod 331 to move back and forth while rotating. The positioning cylinder 51, which is sleeved on the outside of the cylindrical cam 5 on the stirring cylinder 2, provides guidance and positioning, ensuring that the slide head 52 can move along a predetermined trajectory when the cylindrical cam 5 rotates.

[0024] And refer to Figure 1 and Figure 3 An elastic element 521 connects the slide rod 331 and the slide head 52. A recessed platform 511 is provided on the inner wall of the lower end of the positioning cylinder 51. A limiting ring 512 corresponding to the recessed platform 511 is fixed to the upper peripheral wall of the slide rod 331. The elastic element 521 is specifically a spring sleeved on the slide rod 331, and the elastic element 521 is located between the recessed platform 511 and the limiting ring 512. As the cylindrical cam 5 and the slide rod 331 reciprocate within the positioning cylinder 51, the elastic element 521 can undergo a certain deformation and provide a certain deformation force, which can absorb and buffer the impact and vibration generated by the rotation of the cylindrical cam 5, reducing the impact on the entire system.

[0025] And refer to Figure 3 A flexible cover 6 is fitted onto the connecting rod 332. One end of the flexible cover 6 is fixed to the connecting rod 332, and the other end is fixed to the stirring shaft 3, covering the groove 32. The flexible cover 6 is made of food-grade silicone to prevent cream from seeping from the groove 32 into the cavity 33 and affecting the quality of the cream.

[0026] Further reference Figure 3At least two stirring blades 31 are arranged on opposite sides of the stirring shaft 3, with the two stirring blades 31 on opposite sides having staggered inclination angles. The staggered stirring blades 31 can generate more complex flow patterns, which helps to break laminar flow and promote turbulence, thereby improving mixing efficiency. At the same time, it can reduce dead zones in the mixing drum 2, ensuring that the cream is fully stirred in the mixing drum 2.

[0027] Simultaneously refer to Figure 3 The mixing blade 31 has several through holes 311 that penetrate the mixing blade 31, which can enable the cream to be mixed more quickly and distributed more evenly during the mixing process, thereby improving the mixing efficiency.

[0028] The implementation principle of an electric stirring mechanism for cream production according to an embodiment of this application is as follows:

[0029] When the cream is being churned, the rotating mixing shaft 3 drives the mixing blades 31 to rotate as well. Simultaneously, the rotating mixing shaft 3 drives the cylindrical cam 5, which is coaxially fixed to it, to rotate. The spiral groove on the cylindrical cam 5 engages with the slide head 52 on the inner wall of the positioning cylinder 51, causing the cylindrical cam 5 to move up and down as it rotates with the mixing shaft 3. This causes the slide rod 331 to reciprocate along the length of the mixing shaft 3 while rotating, thus causing the mixing blades 31 to reciprocate up and down while rotating. This helps to break the laminar flow in the cream, promoting turbulence and improving mixing efficiency. It also pushes the cream from the bottom of the mixing drum 2 to the top, and vice versa, effectively reducing dead zones in the drum. This improves the quality and taste of the cream while also accelerating the cream production process and increasing production efficiency.
