Description

Technical Field

[0001] This utility model relates to the technical field of frozen beverage processing equipment, specifically a stirring device that can prevent the sedimentation of ice cream slurry containing solid particles during static or continuous production. Background Technology

[0002] The outer shell of current ice cream is usually formed by coating a mixture of chocolate, condensed milk, whipped cream, and various nut pieces. Due to the large density difference between chocolate and nut pieces, the solid raw materials tend to sink during continuous production or short breaks, resulting in uneven distribution of the mixture and significant differences in the nut content within the coated chocolate shell, affecting the sensory quality and consistency of the product.

[0003] Patent application number CN200820071294.7 discloses a chocolate coating device with granular additives for use in the manufacture of flavored ice cream in the frozen dessert industry. This device consists of a rotating shaft inside a housing, driven by an external electric motor and reducer, with stirring blades arranged in a spiral direction on the shaft. It ensures that the granular additives added to the chocolate not only do not sink to the bottom, but are also thoroughly stirred with the chocolate. During the reciprocating motion of the robotic arm, the additives come into contact with the surface of the ice cream, allowing them to adhere evenly to the ice cream surface and quickly form a condensed frosting that adheres to the ice cream surface.

[0004] However, the above-mentioned patented technology uses a paddle mixer, which has the following drawbacks: (1) The paddle is located at the bottom of the tank, which only achieves horizontal circulation and makes it difficult to effectively lift the solid particles deposited at the bottom to the liquid surface; (2) The stirring dead angle is large, and the area near the tank wall or bottom is still prone to material accumulation; (3) The continuous shearing of the paddle generates a large amount of heat, which can easily cause the chocolate to heat up prematurely, thicken, or even crystallize; (4) Disassembly and cleaning are difficult, which does not meet the requirements of rapid changeover in food hygiene. Therefore, there is an urgent need for an ice cream slurry mixing device that can effectively prevent sedimentation, has low shear, and is easy to clean. Utility Model Content

[0005] The purpose of this invention is to provide an anti-settling stirring device for ice cream slurry containing solid particles, in order to solve the problems mentioned in the background art above:

[0006] (1) How to achieve ice cream slurry anti-settling stirring without sedimentation dead corners and with continuous lifting of solid particles.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An anti-settling stirring device for ice cream slurry containing solid particles;

[0009] It includes a mixing chamber, a partition plate, a mixing shaft, two support bases, and several levers;

[0010] The stirring shaft has several grooves along its axis, each groove corresponding to a certain number of baffles. Guide posts extend from both sides of the baffles. Two support seats are fixedly connected to the bottom sides of the mixing chamber. There is a gap between the stirring shaft and the bottom wall of the mixing chamber. The two ends of the stirring shaft are supported on the two support seats. The support seats have guide ring grooves that cooperate with the guide posts of the baffles. The two sides of the partition plate are fixedly connected to the side walls of the mixing chamber. The lower end of the partition plate is close to the side wall of the stirring shaft. The upper end of the partition plate is lower than the opening height of the mixing chamber. The partition plate and the stirring shaft divide the mixing chamber into a lifting chamber and a mixing chamber.

[0011] The paddle plate rotates with the stirring shaft. When the paddle plate rotates to the position below the partition plate, the guide post of the paddle plate is driven by the guide ring groove of the support seat, and the paddle plate is completely retracted into the groove of the stirring shaft. The rotation direction of the paddle plate in the lifting chamber area is from the bottom of the lifting chamber to the top.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, it also includes a feeding assembly, which includes a main feeding pipeline and several feeding pipes. One end of the feeding pipe is connected to the main feeding pipeline, and the other end of the feeding pipe is connected to the bottom of the mixing chamber. The external raw material feeding pipeline and several feeding pipes enter the mixing chamber.

[0014] Furthermore, a regulating valve is installed on the feed pipe.

[0015] Furthermore, it also includes a recovery chamber, which is fixedly connected to the outer wall of the mixing chamber on the side away from the lifting chamber.

[0016] Furthermore, it also includes a recycling component, which includes a main recycling pipeline and several recycling pipes. One end of each recycling pipe is connected to the main recycling pipeline, and the other end of each recycling pipe is connected to the bottom of the recycling bin.

[0017] Furthermore, the stirring shaft includes a stirring shaft body and two half-shafts on both sides. The two half-shafts are respectively installed and fixed on both sides of the stirring shaft body along the axial direction of the stirring shaft body. The stirring shaft body is located inside the stirring chamber, and the two half-shafts are respectively supported on two support seats.

[0018] Furthermore, one half of the stirring shaft passes through the support base and is connected to the drive motor, which drives the stirring shaft to rotate through this half.

[0019] With this structure, the drive motor rotates the stirring shaft at low speed, and the baffle plate extends or retracts periodically under the control of the guide ring groove. The extended baffle plate in the lifting chamber pushes the nut-containing slurry from the bottom upwards along the arc-shaped chamber wall, past the top of the partition, and into the upper part of the stirring chamber, forming a "bottom-top" vertical circulation. At the same time, the feeding component continuously replenishes the bottom with new slurry, and the recovery chamber maintains a constant liquid level, achieving continuous production. Because the baffle plate only extends on the lifting side, the shearing action is gentle, and the chocolate does not easily heat up; the entire stirring chamber has no dead corners, and the solid particles are always in a suspended state, resulting in a uniform distribution of nuts in the coated product.

[0020] The beneficial effects of this ice cream slurry anti-settling mixing device with solid particles are:

[0021] (1) Significant anti-settling effect, vertical material turning and circulation keeps solid particles suspended throughout the process;

[0022] (2) Low shear and low temperature rise, the dial plate extends intermittently at low speed, the temperature rise of chocolate paste is ≤1℃, and the return of sand is avoided;

[0023] (3) There are no dead corners for hygiene. All surfaces in contact with materials are rounded and can be washed with high-pressure water.

[0024] (4) It has a compact structure and low energy consumption. A single shaft drive can achieve 360° uniform material turning, which has better energy-saving performance than traditional frame mixers. Attached Figure Description

[0036] Please see Figures 1 to 6 .

[0037] This ice cream slurry anti-settling mixing device with solid particles includes a mixing chamber 100, a partition plate 500, a mixing shaft, a recovery chamber 700, a feeding assembly, a recovery assembly, two support bases 400, and four baffles 300.

[0038] The mixing chamber 100 is made of stainless steel and has an opening on the upper surface.

[0039] The stirring shaft includes a stirring shaft body 210 and two half-shafts 220. The two half-shafts 220 are respectively installed and fixed on both sides of the stirring shaft body 210 along the axial direction of the stirring shaft body 210. The stirring shaft body 210 is located at the bottom of the stirring chamber 100.

[0040] The stirring shaft body 210 has four slots 211 along its axial direction. The width of the slots 211 is only enough to accommodate one plate 300, and the depth of the slots 211 can fully accommodate the plate 300. The four slots 211 correspond one-to-one with the four plates 300. Guide posts 310 extend from both sides of the plate 300.

[0041] Two support bases 400 are fixed on the bottom sides of the mixing chamber 100 respectively. The two half shafts 220 of the mixing shaft are supported on the two support bases 400 respectively. There is a gap between the side wall of the mixing shaft body 210 and the bottom wall of the mixing chamber 100. One half shaft 220 of the mixing shaft passes through the support base 400 and is connected to the drive motor 230. The drive motor 230 drives the mixing shaft to rotate through this half shaft 220.

[0042] The support base 400 has a guide ring groove 410 that mates with the guide post 310 of the lever plate 300. The guide ring groove 410 includes an upper curved shape and a lower arc shape.

[0043] The partition plate 500 is fixedly connected to the side wall of the inner cavity of the mixing chamber 100 on both sides. The lower end of the partition plate 500 is close to the side wall of the mixing shaft. The upper end of the partition plate 500 is lower than the opening height of the mixing chamber 100. The partition plate 500 and the mixing shaft divide the inner cavity of the mixing chamber 100 into the lifting chamber 110 and the mixing chamber 120.

[0044] The feeding assembly is located below the mixing chamber 100. The feeding assembly includes a main feeding pipeline 610 and three feeding pipes 620. One end of the feeding pipe 620 is connected to the main feeding pipeline 610, and the other end of the feeding pipe 620 is connected to the bottom of the mixing chamber 100. Each feeding pipe 620 is equipped with a regulating valve 630. The raw materials in the storage tank are pressurized and then enter the mixing chamber 100 through the main feeding pipeline 610 and the three feeding pipes 620.

[0045] The recovery bin 700 is also made of stainless steel. The upper surface of the recovery bin 700 is open, and the opening height of the recovery bin 700 is the same as the opening height of the mixing bin 100. The recovery bin 700 is welded and fixed to the outer wall of the mixing bin 100 on the side away from the lifting chamber 110. The recovery assembly includes a main recovery pipeline 710 and several recovery pipes 720. One end of each recovery pipe 720 is connected to the main recovery pipeline 710, and the other end of each recovery pipe 720 communicates with the bottom of the recovery bin 700.

[0046] In use, the drive motor 230 drives the stirring shaft to rotate, and the lever 300 rotates with the stirring shaft. When the lever 300 rotates to the position below the partition plate 500, the guide post 310 of the lever 300 is driven by the guide ring groove 410 of the support base 400, and the lever 300 is completely retracted into the lever groove 211 of the stirring shaft. When the lever 300 is in other positions, the guide post 310 of the lever 300 is driven by the guide ring groove 410 of the support base 400, and the lever 300 extends out of the lever groove 211 of the stirring shaft.

[0047] The rotating direction of the baffle plate 300 within the lifting chamber 110 is from the bottom to the top of the lifting chamber 110. This causes the slurry originally in the mixing chamber 120 to first enter the bottom of the lifting chamber 110 under the drive of the stirring shaft and the baffle plate 300. As the stirring shaft and the baffle plate 300 continue to rotate, the slurry that has entered the bottom of the lifting chamber 110 is gradually turned upwards. Finally, the slurry crosses the partition plate 500 and re-enters the upper part of the mixing chamber 120, thus achieving the purpose of turning the slurry. Solid raw materials in the ice cream slurry will not cause solid deposition due to prolonged retention at the bottom of the mixing chamber 100.

[0048] The above description is only one embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
