Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, and in particular to a stirring and discharging mechanism and frozen food manufacturing equipment. Background Technology
[0002] As a core component of cold beverage equipment, slush machines are widely used in dessert shops, fast food chains, coffee shops, and home consumption scenarios. Slush machines produce frozen foods such as smoothies, ice cream, and sorbets by stirring pre-cooled raw materials at low temperatures and then outputting the product.
[0003] The snow melting machine uses a refrigeration evaporator to cool the liquid raw materials in the tank into ice flakes. Then, stirring blades scrape off the ice flakes adhering to the surface of the evaporator, and the mixture is stirred at a low temperature for a certain period to form frozen food. Finally, the valve at the discharge port of the tank is opened to discharge the frozen food. However, ordinary stirring blades only have a stirring function. After processing, the frozen food accumulates haphazardly in different locations within the tank. Some frozen food far from the discharge port cannot be discharged in the correct order, resulting in frozen food residue. When a large amount of frozen food accumulates in a particular area of the tank, it can cause localized blockages. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a stirring and discharging mechanism that facilitates the sequential discharge of frozen food and reduces the possibility of blockage and residue; the other objective is to provide a frozen food manufacturing equipment using the above-mentioned stirring and discharging mechanism.
[0005] A stirring and discharging mechanism according to a first aspect of the present invention includes: a cylindrical refrigeration evaporator arranged vertically; a rotating shaft passing through the refrigeration evaporator along its central axis; a rotating impeller connected to the rotating shaft, the rotating impeller having at least one stirring blade abutting against the outer peripheral wall of the refrigeration evaporator, the stirring blade extending along the axial direction of the refrigeration evaporator; a material hopper fitted over the stirring blade and the refrigeration evaporator, the bottom wall of the material hopper having a discharge port; wherein the lower part of the stirring blade has a lower pressure plate portion inclined relative to the rotating shaft.
[0006] The mixing and discharging mechanism according to the embodiments of the present utility model has at least the following beneficial effects:
[0007] When the above-mentioned mixing and discharging mechanism is working, the refrigeration evaporator cools the liquid raw material on its surface. The rotating impeller on the shaft is driven by the motor to rotate. The mixing blades can scrape the raw material located on the outer peripheral wall of the refrigeration evaporator and mix it to form frozen food. The frozen food falls along the mixing blades and falls near the lower pressure plate under the action of gravity. As the lower pressure plate rotates with the mixing blades, it gradually approaches the discharge port, thereby squeezing the frozen food out of the discharge port in sequence, reducing the possibility of blockage and residue.
[0008] In some embodiments of this utility model, the lower pressure plate is an arc-shaped plate that is inclined downward and protrudes, the convex arc surface of the arc plate faces the rotating shaft, and the included angle between the arc plate and the ground of the material barrel gradually increases from bottom to top.
[0009] In some embodiments of this utility model, the stirring blade is provided with an inclined plate section extending upward along the upper end of the arc-shaped plate, and the angle between the lower side of the inclined plate section and the outer peripheral wall of the refrigeration evaporator is always an acute angle.
[0010] In some embodiments of this utility model, the rotating shaft extends downward below the refrigeration evaporator, the rotating impeller includes a bracket connected to the lower end of the rotating shaft, and at least two stirring blades are evenly distributed circumferentially around the axial direction of the rotating shaft on the bracket, the stirring blades extending along the axial direction of the refrigeration evaporator while being arranged circumferentially around the refrigeration evaporator.
[0011] In some embodiments of this utility model, the support includes a transverse stiffener and a circular ring plate perpendicular to the rotating shaft. The middle position of the transverse stiffener is provided with a bushing for inserting the rotating shaft. The circular ring plate is located above the transverse stiffener and is sleeved on the outer periphery of the refrigeration evaporator. The two ends of the stirring blade are connected between the transverse stiffener and the circular ring plate to form a frame structure. The number of circles of the stirring blade around the refrigeration evaporator is less than one.
[0012] In some embodiments of this utility model, the bracket further includes two vertical stiffening plates arranged symmetrically about the axis of rotation. The lower ends of the two vertical stiffening plates are respectively connected to the two ends of the horizontal stiffening plate, and the upper ends of the vertical stiffening plates are connected to the annular plate.
[0013] In some embodiments of this utility model, the number of stirring blades is two, the stirring blades are arranged around the circumference of the refrigeration evaporator at an angle of less than 180°, the lower end of the stirring blades is connected to both the lower end of the vertical stiffener and one end of the horizontal stiffener, and the annular plate, the vertical stiffener and the corresponding stirring blades form a triangular region.
[0014] In some embodiments of this utility model, the outer edges of the upper and middle parts of the vertical stiffener are formed with relief grooves that are recessed inward along the width direction of the vertical stiffener.
[0015] In some embodiments of this utility model, the annular plate, the transverse stiffener, the bushing, the two stirring blades, and the two vertical stiffeners are an integral plastic structure or an integral metal structure.
[0016] A frozen food manufacturing apparatus according to a second aspect of the present invention includes a stirring and discharging mechanism as described in any of the above technical solutions. Frozen food falls along the stirring blades and, under the influence of gravity, lands near the lower pressure plate.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0026] In the description of this utility model, it should be understood that the directional descriptions, such as the terms "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] See Figures 1 to 3 This utility model discloses a stirring and discharging mechanism, comprising: a cylindrical refrigeration evaporator 100 arranged vertically; a rotating shaft 200 passing through the refrigeration evaporator 100 along its central axis; a rotating impeller 300 connected to the rotating shaft 200, the rotating impeller 300 having at least one stirring blade 310 abutting against the outer peripheral wall of the refrigeration evaporator 100, the stirring blade 310 extending along the axial direction of the refrigeration evaporator 100; a material tank 400 sleeved around the stirring blade 310 and the refrigeration evaporator 100, the bottom wall of the material tank 400 having a discharge port 410 extending through it; wherein, the lower part of the stirring blade 310 has a lower pressure plate portion 311 inclined relative to the rotating shaft 200.
[0030] The material tank 400 contains liquid raw materials for making frozen food. When the above-mentioned stirring and discharging mechanism is working, the refrigeration evaporator 100 cools the liquid raw materials on its surface to form an ice-water mixture. The rotating impeller 300 on the rotating shaft 200 is driven by the motor to rotate. The stirring blades 310 can scrape down the ice-water mixture located on the outer peripheral wall of the refrigeration evaporator 100 and stir it to form frozen food. The frozen food falls along the stirring blades 310 and falls near the lower pressure plate 311 under the action of gravity. As the lower pressure plate 311 rotates with the stirring blades 310, it gradually approaches the discharge port 410, forming a downward thrust, thereby squeezing the frozen food out of the discharge port 410 in sequence, reducing the possibility of blockage and residue.
[0031] See Figures 1 to 3 In some embodiments of this utility model, the lower pressure plate 311 is an arc-shaped plate that protrudes downwards at an angle. The convex surface of the arc-shaped plate faces the rotating shaft 200, and the angle between the arc-shaped plate and the ground of the material barrel 400 gradually increases from bottom to top. As the stirring blade 310 rotates to approach the discharge port 410, the frozen food moves downwards along the surface of the arc-shaped plate towards the discharge port 410. Under the squeezing action of the convex surface of the arc-shaped plate, it is pushed towards the discharge port 410, allowing the frozen food to be discharged in an orderly and smooth manner, avoiding the problem of blockage caused by excessive flow.
[0032] See Figure 1 and Figure 2 In some embodiments of this utility model, the stirring blade 310 is provided with an inclined plate section 312 extending upward along the upper end of the arc-shaped plate. The angle between the lower side of the inclined plate section 312 and the outer peripheral wall of the refrigeration evaporator 100 is always an acute angle. The inclined plate section 312 and the arc-shaped plate are together attached to the outer peripheral wall of the refrigeration evaporator 100 to scrape off the cooled raw material. After stirring, frozen food is formed. The lower side of the inclined plate section 312 is the surface facing the discharge port 410. The angle between the lower side of the inclined plate section 312 and the outer peripheral wall of the refrigeration evaporator 100 is always an acute angle. The frozen food attached to the lower side of the inclined plate section 312 can rotate in the clockwise direction of the rotating impeller 300 without being thrown behind the rotation direction of the inclined plate section 312, ensuring that the frozen food produced earlier does not have any residue.
[0033] See Figure 2 and Figure 3In some embodiments of this utility model, the rotating shaft 200 extends downward below the refrigeration evaporator 100, and the rotating impeller 300 includes a support 320 connected to the lower end of the rotating shaft 200. At least two stirring blades 310 are evenly distributed circumferentially around the axial direction of the rotating shaft 200 on the support 320, which is beneficial to the force balance of the rotating impeller 300 during rotation. The stirring blades 310 extend along the axial direction of the refrigeration evaporator 100 and are arranged around the circumference of the refrigeration evaporator 100, which is beneficial to drive the frozen food to generate a downward rotational movement.
[0034] See Figure 2 and Figure 3 In some embodiments of this utility model, the support 320 includes a transverse stiffener 321 and an annular plate 322 perpendicular to the rotating shaft 200. The transverse stiffener 321 has a bushing portion 323 for inserting the rotating shaft 200 at its middle position. The annular plate 322 is located above the transverse stiffener 321 and is sleeved on the outer periphery of the refrigeration evaporator 100. The two ends of the stirring blade 310 are connected between the transverse stiffener 321 and the annular plate 322 to form a frame structure. The number of turns of the stirring blade 310 around the refrigeration evaporator 100 is less than one. Understandably, the annular plate 322 is fitted around the outside of the refrigeration evaporator 100, and the transverse stiffener 321 is located below the refrigeration evaporator 100. The transverse stiffener 321, the annular plate 322, and all the stirring blades 310 form a frame structure to achieve stable rotation of the rotating impeller 300. The number of rings of the stirring blades 310 around the refrigeration evaporator 100 is less than one, which can effectively prevent frozen food from sticking to the surface of the stirring blades 310.
[0035] See Figure 2 and Figure 3 In some embodiments of this utility model, the support 320 further includes two vertical stiffening plates 324 symmetrically arranged about the rotating shaft 200. The lower ends of the two vertical stiffening plates 324 are respectively connected to the two ends of the horizontal stiffening plate 321, and the upper ends of the vertical stiffening plates 324 are connected to the annular plate 322. The arrangement of the two vertical stiffening plates 324 makes the horizontal stiffening plate 321, the annular plate 322, the two stirring blades 310 and the two vertical stiffening plates 324 form a more stable frame structure, improving rotational stability and further preventing the stirring blades 310 from deforming and affecting the scraping of frozen food.
[0036] See Figure 2 and Figure 3In some embodiments of this utility model, the number of stirring blades 310 is two. The stirring blades 310 are arranged around the circumference of the refrigeration evaporator 100 at an angle of less than 180°. The lower end of the stirring blades 310 is connected to the lower end of the vertical stiffener 324 and one end of the horizontal stiffener 321. The annular plate 322, the vertical stiffener 324 and the corresponding stirring blades 310 form a triangular area, so that the support 320 has a lot of open space to accommodate frozen food, but still has strong mechanical strength.
[0037] See Figure 2 and Figure 3 In some embodiments of this utility model, the outer edges of the upper and middle parts of the vertical rib 324 form recessed grooves 325 along the width direction of the vertical rib 324. It should be noted that the annular plate 322, the vertical rib 324, and the corresponding stirring blades 310 form a triangular region. This triangular region, together with the inner circumferential wall of the cylinder, forms a closed chamber, affecting the flowability of frozen foods and preventing mixing and stirring of the frozen foods in the circumferential direction. The recessed grooves 325 solve this problem.
[0038] In some embodiments of this utility model, to simplify the production and processing flow, the annular plate 322, the transverse stiffener 321, the bushing portion 323, the two stirring blades 310, and the two vertical stiffeners 324 are integral plastic structures or integral metal structures. The integral plastic rotating impeller 300 is obtained by injection molding, while the integral metal rotating impeller 300 can be obtained by casting or machining.
[0039] See Figure 4 This utility model also discloses a frozen food manufacturing equipment, including a main body 500, on which a stirring and discharging mechanism of any of the above-mentioned technical solutions is provided. Frozen food falls along the stirring blades 310 and into the vicinity of the lower pressure plate 311 under the action of gravity. As the lower pressure plate 311 rotates with the stirring blades 310, it gradually approaches the discharge port 410, thereby sequentially squeezing the frozen food out of the discharge port 410, reducing the possibility of blockage and residue.
[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.
[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
