Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electrical appliances, and in particular relates to a spiral mixer and frozen food manufacturing equipment. Background Technology
[0002] In frozen food manufacturing equipment, beverage solutions are typically cooled and stirred within a mixing chamber to create frozen foods, such as slush machines, slush machines, ice cream machines, or smoothie machines. These are specialized equipment for making slush soft-serve ice cream and smoothies. Taking a slush machine as an example, it utilizes a compressor to rapidly cool the liquid in the mixing chamber below 0°C. Combined with a stirring component within the mixing chamber, the liquid is stirred and solidified into a smoothie. During operation, the stirring component continuously rotates within the mixing chamber, causing the liquid and the internal smoothie to rotate together, pushing the smoothie towards the front outlet. This propulsion is primarily achieved by the rotation of the curved (spiral) fan blades at the front of the stirring component. Due to the force of this force, the smoothie and other materials also diffuse outwards along the surface of the fan blades, resulting in most of the material being located on the outer side of the fan blades, while the center of the fan blades lacks material, leading to uneven mixing and affecting the production of smoothie products. Utility Model Content
[0003] The purpose of this invention is to provide a spiral mixer that optimizes the mixing structure, enabling more uniform mixing.

This solution also adds a material blocking part extending to the front side on the first pushing blade, which can block the material from moving outward in the direction of material rotation during mixing, and avoid the material from accumulating on the outside of the first pushing blade, thus preventing uneven mixing and improving the mixing effect.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] like Figures 1 to 3 As shown, this embodiment of the present invention provides a spiral mixer, including a spiral blade 1, an assembly part 2, and a first pushing blade 31. The spiral blade 1 has a spiral stirring part 11 spirally arranged along its own rotation axis. The assembly part 2 is located on the front side of the spiral blade 1 and is coaxially arranged with the rotation axis of the spiral blade 1. The first pushing blade 31 is connected to the front side of the spiral blade 1. The entire spiral mixer can be connected to a drive via the assembly part to achieve rotation. Through the spiral blade and the first pushing blade on the front side, it pushes the material to the front side while rotating and stirring the material.
[0029] In this design, the first pusher blade 31 extends forward along a spiral and is connected to the assembly part 2. The first pusher blade 31 also has a baffle part 30 located on the surface of the first pusher blade 31 and extending forward. By adding a baffle part extending forward on the first pusher blade, it can prevent the material from moving outward in the direction of material rotation during mixing, thus avoiding the material from accumulating on the outside of the first pusher blade and causing uneven mixing, thereby improving the mixing effect.
[0030] like Figure 3 As shown in the diagram, the dotted line represents the flow direction of the material along the first pusher blade 3 during stirring. In this embodiment, the baffle 30 extends forward, protruding forward on the surface of the first pusher blade 3, thereby preventing the material from sliding outward along the surface of the first pusher blade 3. It can be positioned so that the material is on its rotational trajectory at an angle to the direction of rotation to achieve this blocking effect. In a preferred embodiment, the baffle 30 is located at the front end of the first pusher blade 31 and extends inward from the outer periphery of the first pusher blade 31 along its end edge. That is, it protrudes from the end to block the material sliding along the first pusher blade 31 to the end. Furthermore, during rotation, it can guide some of the blocked material to the center position in the direction of the rotation axis, thereby improving the stirring effect.
[0031] Of course, in this embodiment, the baffle portion 30 extends forward, and it can extend forward at an angle relative to the first pusher blade 31. As a preferred embodiment, this solution adopts the baffle portion 30 extending forward along the axial direction of the spiral blade 1. That is, it is equivalent to the arrangement perpendicular to the connection point with the surface of the first pusher blade 31, which has a better baffle and guiding effect. In addition, the front end of the baffle portion 30 is a straight edge extending vertically, so that the baffle portion 30 has a vertical baffle wall 301 with a thickness that gradually increases from the outer periphery of the first pusher blade 31 to the inner side. The vertical baffle wall 301 forms the obstruction for the material to slide along the first pusher blade 31, and its front side is a vertical straight edge structure, which is beneficial to the cooperation with the inner wall of the mixing chamber in application. Generally, the inner wall of the mixing chamber is also flat, and the straight edge structure makes it maintain a gap with the inner wall to better stir and push the material in the mixing chamber.
[0032] Furthermore, the baffle 30 described in this solution also has a horizontal baffle 302, which bends from the inner end of the vertical baffle 301 in a spiral direction. This strengthens the vertical baffle 301, making it more durable.
[0033] To further improve the mixing effect, this embodiment of the invention also includes a second pushing blade 32, which is connected to the assembly part 2 and is spirally symmetrically arranged with the first pushing blade 31. The second pushing blade 32 increases the contact area with the material. Although it is also spirally oriented, it does not have a forward-extending baffle. During its rotation and pushing process, its mixing effect on the material is similar to that of a traditional mixing fan blade, which can be understood as dispersing the material. Under the action of the baffle 30 of the synchronously rotating first pushing blade 31, the material is promptly collected, ensuring that there are no gaps near the center of the rotating shaft, thus achieving uniform mixing.
[0034] Furthermore, in this design, one end of the second pushing blade 32 is connected to the front side of the spiral blade 1, and the other end is a blade tip 320 extending along the spiral direction. The front surface of the blade tip 320 is in the same vertical plane as the front end face of the baffle part 30. This also facilitates cooperation with the inner wall of the mixing chamber during application, so as to better stir and push the material in the mixing chamber.
[0035] In this embodiment of the invention, the spiral blade 1 further includes a support rod assembly 12 arranged axially. The support rod assembly 12 is arranged parallel to each other in the circumferential direction, and the spiral stirring part 11 is spirally wound around the support rod assembly 12. The spiral stirring part 11 and the support rod assembly 12 together form a central cavity. In application, the cavity is fitted onto the cooling component, and the assembly part 2 is installed with the drive shaft of the driving component, so that the spiral stirring part 11 is arranged spirally along the surface of the cooling component. In this way, while the material is cooled by the cooling component in the cavity, the rotating spiral stirring part 11 stirs and pushes the material. In this solution, the support rod assembly 12 consists of at least two parallel and oppositely arranged support rods. As a preferred embodiment, this solution uses three parallel support rods, and the three support rods are spaced apart in the circumferential direction.
[0036] To facilitate the installation of the helical agitator, this design also includes a support ring 13, which is located at the rear end of the helical blade 1 and connected to at least two of the support rods. The support ring 13 serves to support the helical agitator 11 in conjunction with the support rods and facilitates installation with the cooling component. The support ring 13 is constructed as a segment of a ring, but in this design, it is designed as a semicircle. Similarly, the aforementioned multiple support rods are spaced apart along the semicircular support ring 13. Alternatively, the support ring 13 can be designed as a complete circle.
[0037] In this design, the spiral blade 1, assembly part 2, first pusher blade 31, stop part 30, and second pusher blade 32 are integrally molded. This results in a simple structure and ease of manufacturing. Similarly, the support ring 13 in this design is also integrally molded with the aforementioned structure.
[0038] like Figure 4 , Figure 5 As shown in the figure, this utility model embodiment also provides a frozen food manufacturing device, including a body 9, a mixing chamber 91 provided on the body 9, and the aforementioned spiral stirring body provided inside the mixing chamber 91. It is used to manufacture frozen foods such as smoothies, and the use of the aforementioned spiral stirring body makes the manufactured smoothies have a finer texture.
[0039] This invention provides a spiral mixer that, through spiral blades and a first pushing blade on the front side, pushes the material to the front while rotating and mixing it. This design also adds a baffle extending forward on the first pushing blade, which can block the material from moving outward in the direction of the material's rotation during mixing, thus preventing the material from concentrating on the outside of the first pushing blade and causing uneven mixing, thereby improving the mixing effect.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.
