Description

Technical Field

[0002] Snow melters are an indispensable food processing equipment in the cold drink industry and are widely used. When using a snow melter, users need to pour liquids such as juice and dairy products into its storage barrel. At present, the storage barrel of the snow melter usually integrates a motor, a pushing mechanism and a cooling mechanism. When the snow melter is started, the evaporator of the cooling mechanism will start to work, refrigerate the liquid, and gradually freeze it and form ice crystals. In order to prevent the ice crystal mixture from agglomerating into large ice cubes, the motor will drive the pushing mechanism to stir the ice crystal mixture. The pushing mechanism is usually a spiral scraper, which will rotate, stir and push the solid-liquid mixture inside the storage barrel to ensure that the ice crystals are refined into ice smoothies with obvious particles. However, the scraper of the existing snow melter is usually a flat strip structure, which can only play a pushing role and a little stirring role, and cannot achieve full stirring of the ice crystal mixture. In addition, the fluidity of the ice crystal mixture is insufficient, so only ice smoothie solids with larger particles can be made, and it is impossible to make "ice cream"-like solids with smaller particles and softer shapes.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0021] See also Figure 1The embodiment of the utility model discloses a material pushing and stirring device for a vertical snow melting machine, which is connected to a driving motor 6 and arranged in a material storage barrel 5, and includes a driving part 1 and a scraper part 2 connected to the driving part 1, wherein the driving part 1 includes a connecting disk 11, and the connecting disk 11 is connected to the driving motor 6, and the driving motor 6 can drive the scraper part 2 to push and stir in the material storage barrel 5 through the connecting disk 11, wherein the scraper part 2 is covered outside the evaporator 7 of the cooling mechanism, and the ice crystal mixture is in the evaporator 7. Between the outer wall and the inner wall of the storage barrel 5, one end of the scraper portion 2 is connected to the connecting disk 11, and the other end of the scraper portion 2 spirally extends in a direction away from the connecting disk 11. The central axis of the connecting disk 11 coincides with the axis of the spiral line of the scraper portion 2. The scraper portion 2 can rotate around the connecting disk 11. Since the scraper portion 2 is spiral, the scraper portion 2 can push the ice crystal mixture to move in a direction away from the connecting disk 11, that is, the bottom of the storage barrel 5 moves when rotating.

[0022] Traditional snow melters are mostly horizontal structures, with the drive motor 6 placed horizontally and connected to the scraper horizontally, and the storage barrel 5 placed horizontally. When the drive motor 6 drives the scraper to rotate, it can push the ice crystal mixture to move horizontally, and the ice crystal mixture is easy to gather at one end of the storage barrel 5. The traditional snow melter sets a backflow surface at this end of the storage barrel 5, so that the ice crystal mixture can flow back from the backflow surface to the upper or lower side of the storage barrel 5, preventing the ice crystal mixture from gathering and forming large ice blocks after being compressed. Traditional scrapers are all flat strip structures, which can only play a pushing role and a little stirring role, and cannot fully stir the ice crystal mixture, nor can they increase contact with the air. Therefore, what is finally formed is large solid particles, that is, ice smoothie.

[0023] In the embodiment of the present invention, the pushing mechanism for the vertical snow melting machine is applied to the vertical snow melting machine, the driving motor 6 is connected to the top of the scraper part 2, the scraper part 2 covers the surface of the evaporator 7, and can rotate between the evaporator 7 and the storage barrel 5. When the scraper part 2 rotates, it can push the ice crystal mixture to move downward, and under the influence of gravity, the ice crystal mixture is more likely to gather and gather at the bottom of the storage barrel 5. It is not easy for the ice crystal mixture to overcome gravity and flow back by opening the backflow surface. Therefore, compared with the horizontal snow melting machine, there are two problems when the scraper part 2 is applied to the vertical snow melting machine to make "ice cream" or "ice cream". One is that the existing scraper structure cannot fully stir the ice crystal mixture, and the other is that the existing storage barrel 5 structure cannot make the ice crystal mixture flow back smoothly, and cannot avoid aggregation to form ice cubes.

[0024] In order to solve the above problem, the scraper part 2 is provided with a notch 23 on one side close to the central axis of the connecting disk 11 and on one side away from the central axis of the connecting disk 11. The edge of the scraper part 2 close to the central axis of the connecting disk 11 is equivalent to the inner edge of the scraper part 2, and the edge of the scraper part 2 away from the central axis of the connecting disk 11 is equivalent to the outer edge, that is, the notch 23 is provided on both the outer edge and the inner edge of the scraper part 2. By providing the notch 23, the flow of the ice crystal mixture in the storage barrel 5 can be greatly facilitated. Under the downward squeezing force of the scraper part 2, the ice crystal mixture can be refluxed, mixed and dispersed in each notch 23, so that the ice crystal mixture can smoothly reflux from the bottom of the storage barrel 5 to the middle or top, and the fluidity is improved, which can avoid gathering at the bottom to form ice cubes. In addition, the flow, mixing and dispersion of the ice crystal mixture in the storage barrel 5 further enhance the stirring effect, so that the ice crystal mixture is fully mixed with the air, and a soft shape and delicate taste "ice cream" solid can be formed.

[0025] The beneficial effects of the embodiments of the utility model are as follows:

[0026] The pushing and stirring device for a vertical snow melter according to the utility model embodiment is provided with a driving part 1 and a scraper part 2 connected to the driving part 1, wherein a driving motor 6 can drive the scraper part 2 to rotate in the storage barrel 5 through the driving part 1 to push and stir the ice crystal mixture. In order to fully stir the ice crystal mixture, the scraper part 2 is provided with a notch 23 on one side close to the central axis of the connecting disk 11 and on the edge of the side away from the central axis of the connecting disk 11, that is, the inner and outer sides of the scraper part 2 are provided with notches 23. During stirring, due to the presence of the notches 23, the ice crystal mixture can flow, mix and disperse between the notches 23, and under the stirring of the scraper part 2, the ice crystal mixture will repeat the process of stirring, flowing, mixing and dispersing, thereby improving the fluidity of the ice crystal mixture and increasing the contact between the ice crystal mixture and the air, thereby improving the stirring effect, thereby forming a "ice cream"-like solid with a softer shape and smaller particles.

[0027] Specifically, see Figure 2The scraper part 2 includes a first scraper part 21 and a second scraper part 22. The pusher mechanism for the vertical snow melter also includes a connection part 3. The connection part 3 is symmetrically arranged on both sides of the connection disk 11 and is respectively connected to the first scraper part 21 and the second scraper part 22. The first scraper part 21 and the second scraper part 22 extend downward from the connection part 3 in an interlaced spiral. The first scraper part 21 and the second scraper part 22 are both spiral-shaped, with equal "pitch" and "radius", and are respectively arranged on both sides of the connection disk 11 in an interlaced manner, which can increase the contact between the scraper part 2 and the ice crystal mixture.

[0028] The notch 23 includes a first inner notch 211 and a first outer notch 212. The first inner notch 211 is provided on one side of the first scraper portion 21 close to the central axis of the connecting disk 11, and the first outer notch 212 is provided on one side of the first scraper portion 21 far from the central axis of the connecting disk 11. The number of the first inner notch 211 and the first outer notch 212 is greater than 1. That is, the first inner notch 211 and the first outer notch 212 are respectively located at the inner edge and the outer edge of the first scraper portion 21, and the ice crystal mixture can obtain flow space on the inner side and the outer side of the first scraper portion 21, which increases the fluidity of the ice crystal mixture and improves the stirring and mixing effect.

[0029] In addition, the pushing and stirring device for the vertical snow melter is also provided with a convex plate 24, which can increase the degree of stirring when the scraper part 2 contacts the ice crystal mixture, and helps to fully stir. Specifically, the convex plate 24 includes a first outer convex plate 213 and a first inner convex plate 214, the first outer convex plate 213 is arranged on the side of the first inner notch 211 away from the central axis of the connecting disk 11, and the first inner convex plate 214 is arranged on the side of the first outer notch 212 close to the central axis of the connecting disk 11, that is, the first outer convex plate 213 is arranged on the outer side of the first inner notch 211, and the first inner convex plate 214 is arranged on the inner side of the first outer notch 212, the first outer convex plate 213 corresponds to the position of the first inner notch 211, and the first inner convex plate 214 corresponds to the position of the first outer notch 212. The number of the first outer convex plate 213 and the first inner convex plate 214 are both multiple. When the first outer convex plate 213, the first inner convex plate 214, the first inner notch 211 and the first outer notch 212 are distributed, the first inner convex plate 214 and the first inner notch 211 are alternately arranged on the inner side of the first scraper part 21, and the first outer convex plate 213 and the first outer notch 212 are alternately arranged on the outer side of the first scraper part 21. By alternately arranging, the ice crystal mixture can be stirred and flowed more evenly in the vertical direction both inside and outside. For example, the ice crystal mixture moves under the pressure of the first outer convex plate 213. Since the first outer notch 212 is provided at both ends of the first outer convex plate 213, and the two first outer notches 212 are respectively provided at the upper end and the lower end of the first outer convex plate 213, the ice crystal mixture will flow toward the first outer notches 212 at the upper and lower ends under pressure in the vertical direction, which promotes the fluidity in the vertical direction and improves the stirring effect in the vertical direction.

[0030] Similarly, the notch 23 further includes a second inner notch 221 and a second outer notch 222, wherein the second inner notch 221 is disposed on one side of the second scraper portion 22 close to the central axis of the connecting disk 11, and the second outer notch 222 is disposed on one side of the second scraper portion 22 away from the central axis of the connecting disk 11, and the number of the second inner notch 221 and the second outer notch 222 is greater than 1. That is, the second inner notch 221 and the second outer notch 222 are respectively located at the inner edge and the outer edge of the second scraper portion 22, and the ice crystal mixture can obtain flow space on both the inner and outer sides of the second scraper portion 22, thereby increasing the fluidity of the ice crystal mixture and improving the stirring and mixing effect.

[0031] Similarly, the convex plate 24 includes a second outer convex plate 223 and a second inner convex plate 224, wherein the second outer convex plate 223 is disposed on a side of the second inner notch 221 away from the central axis of the connecting disk 11, and the second inner convex plate 224 is disposed on a side of the second outer notch 222 close to the central axis of the connecting disk 11, that is, the second outer convex plate 223 is disposed on the outer side of the second inner notch 221, and the second inner convex plate 224 is disposed on the inner side of the second outer notch 222, and the second outer convex plate 223 corresponds to the position of the second inner notch 221, and the second inner convex plate 224 corresponds to the position of the second outer notch 222. The number of the second outer convex plate 223 and the second inner convex plate 224 are both multiple, and the second inner convex plate 224 and the second inner notch 221 are alternately disposed on the inner side of the second scraper portion 22, and the second outer convex plate 223 and the second outer notch 222 are alternately disposed on the outer side of the second scraper portion 22. By alternating the arrangement, the ice crystal mixture can be stirred and flowed more evenly in the vertical direction both on the inside and the outside. For example, the ice crystal mixture moves under the extrusion of the second inner convex plate 224. Since the second inner notches 221 are provided at both ends of the second inner convex plate 224, the two second inner notches 221 are respectively provided at the upper and lower ends of the second inner convex plate 224. Therefore, in the vertical direction, the ice crystal mixture will flow toward the second inner notches 221 at the upper and lower ends under extrusion. Therefore, in the vertical direction, the ice crystal mixture will produce a flow-stirring-flow-stirring effect, which not only promotes the fluidity in the vertical direction, but also improves the stirring effect in the vertical direction.

[0032] Further, the position of the first outer convex plate 213 in the first scraper portion 21 corresponds to the position of the second outer notch 222 in the second scraper portion 22, and the position of the first inner convex plate 214 in the first scraper portion 21 corresponds to the position of the second inner notch 221 in the second scraper portion 22. That is, the heights of the first outer convex plate 213 and the second outer notch 222 correspond, and the heights of the first inner convex plate 214 and the second inner notch 221 correspond. In the same horizontal cross section, when the horizontal cross section contacts the first scraper part 21 with the first outer convex plate 213 on the outside and the first inner notch 211 on the inside, the horizontal cross section contacts the second scraper part 22 with the second outer notch 222 on the outside and the second inner notch 224 on the inside. Similarly, when the horizontal cross section contacts the first scraper part 21 with the first outer notch 212 on the outside and the first inner notch 214 on the inside, the horizontal cross section contacts the second scraper part 22 with the second outer convex plate 223 on the outside and the second inner notch 221 on the inside. The notch 23 of the first scraper part 21 and the convex plate 24 of the second scraper part 22 are located at the same height. Since the notch 23 of the first scraper part 21 and the convex plate 24 are located at the same positions, and the convex plate 24 of the second scraper part 22 and the notch 23 are located at the same height as the convex plate 24 of the first scraper part 21, the notch 23 of the second scraper part 22 and the convex plate 24 of the first scraper part 21 are located at the same height.

[0033] Through the corresponding arrangement at the height, the fluidity of the ice crystal mixture can be promoted in the horizontal direction, thereby improving the stirring effect. For example, during rotation, the scraper portion 2 pushes the ice crystal mixture to move, and the ice crystal mixture generates a horizontal movement component in the storage barrel 5. The ice crystal mixture can pass through the first outer notch 212, the first inner notch 211, the second outer notch 222 and the second inner notch 221 in the horizontal movement component to produce a flow effect. At the same height, the positions of the second outer convex plate 223, the second inner convex plate 224, the first outer convex plate 213 and the first inner convex plate 214 respectively correspond to the positions of the first outer notch 212, the first inner notch 211, the second outer notch 222 and the second inner notch 221. Therefore, the ice crystal mixture will encounter the second outer convex plate 223, the second inner convex plate 224, the first outer convex plate 213 and the first inner convex plate 214 respectively. These convex plates 24 will push the ice crystal mixture to produce a stirring effect. Therefore, in the horizontal direction, the ice crystal mixture will produce a repeated stirring and flow effect of flow-stirring-flow-stirring, which not only promotes the fluidity in the horizontal direction, but also improves the stirring effect in the horizontal direction.

[0034] Therefore, by arranging the alternating distribution between the notches 23 and the convex plates 24, and the corresponding height arrangements of the notches 23 and the convex plates 24, repeated stirring and flowing effects in both vertical and horizontal directions can be achieved simultaneously, thereby comprehensively improving fluidity and stirring effects in three dimensions.

[0035] In addition, see Figure 3 The pusher mechanism for the vertical snow melter also includes a scraper support part 4, which includes a first upper support piece 41, a second upper support piece 42, a first lower support piece 43 and a second lower support piece 44. The first upper support piece 41 is vertically connected between the connection part 3 and the upper side of the first scraper part 21, and the second upper support piece 42 is vertically connected between the connection part 3 and the upper side of the second scraper part 22; one end of the first lower support piece 43 is connected to the bottom side of the first scraper part 21, and the other end of the first lower support piece 43 extends vertically downward, one end of the second lower support piece 44 is connected to the bottom side of the second scraper part 22, and the other end of the second lower support piece 44 extends vertically downward. The first upper support piece 41 can fix the first scraper part 21, the second upper support piece 42 can fix the second scraper part 22, the first lower support piece 43 can support the first scraper part 21, and the second lower support piece 44 can support the second scraper part 22.

[0036] Furthermore, the first upper support sheet 41, the second upper support sheet 42, the first lower support sheet 43 and the second lower support sheet 44 not only play a fixing or supporting role, but also play a role in further stirring, grinding and flow guiding of the ice crystal mixture. Specifically, the planes of the first upper support sheet 41 and the second upper support sheet 42 are parallel to each other, the planes of the first lower support sheet 43 and the second lower support sheet 44 are parallel to each other, the first upper support sheet 41 is inclined from the outer edge of the first scraper portion 21 to the direction where the bottom end of the first scraper portion 21 is located, and the second upper support sheet 42 is inclined from the outer edge of the second scraper portion 22 to the direction where the bottom end of the second scraper portion 22 is located. The first upper support sheet 41 and the first lower support sheet 43 are arranged in different directions, and the second upper support sheet 42 and the second lower support sheet 44 are arranged in different directions. When rotating, the first upper support sheet 41 and the second upper support sheet 42 can guide the ice crystal mixture to the inner side of the scraper portion 2, so that the ice crystal mixture will stick to the outer side wall of the evaporator 7, and the first upper support sheet 41 and the second upper support sheet 42 can stir and grind the ice crystal mixture to obtain smaller ice crystals, and the first lower support sheet 43 and the second lower support sheet 44 can stir and grind the first upper support sheet 41 and the second upper support sheet 42 to obtain smaller ice crystals. The ice crystal mixture ground by the support sheet 41 and the second upper support sheet 42 is scraped out from the outer wall of the evaporator 7, and the ice crystal mixture is guided close to the outer side of the scraper portion 2, so that a part of the ice crystal mixture will continue to be stirred by the scraper portion 2, and a part of the ice crystal mixture will stick to the inner wall of the storage barrel 5, and the outer edges of the first lower support sheet 43 and the second lower support sheet 44 continue to grind this part of the ice crystal mixture. At the same time, the guidance of the first lower support sheet 43 and the second lower support sheet 44 can make the ice crystal mixture closer to the outlet at the bottom of the storage barrel 5, which is convenient for subsequent discharge.

[0037] In order to further improve the stability of the first scraper portion 21 and the second scraper portion 22, the scraper support portion 4 also includes vertically arranged support ribs 45, and the support ribs 45 are connected between the first scraper portion 21 and the second scraper portion 22. The number of the support ribs 45 can be 2, which can fix the first scraper portion 21 and the second scraper portion 22 from both sides, and can improve the connection stability of the first scraper portion 21 and the second scraper portion 22 to ensure the stirring and pushing effects.

[0038] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications are also considered to be within the protection scope of the present utility model.
