Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ice cream production, in particular to a multi-layer segmented ice cream stirring device. BACKGROUND

[0002] The ice cream stirring device is a core equipment in the process of making ice cream, which integrates stirring and mixing with cooling and solidification functions. Through the rotation of the stirring shaft, the device drives the stirrer to fully mix the ice cream raw materials, ensuring that each part is evenly blended. At the same time, the built-in condenser continuously cools the raw materials during stirring, causing them to gradually solidify into smooth and smooth ice cream. By adjusting the speed of the stirring shaft, the amount of air injected into the ice cream can also be controlled, thereby producing ice cream products with different textures.

[0003] However, the existing ice cream stirring equipment has low stirring efficiency, which makes the mixing and cooling speed of the raw materials not ideal during the preparation of ice cream, which may result in the texture of the ice cream not being fine enough, and in some cases, the raw materials do not fully blend, affecting the taste and flavor of the finished product. For example, Chinese patent CN202110922952.9 proposes an ice cream machine and an ice cream preparation method, which includes a stirring cylinder inside which is provided with a stirring mechanism, the stirring mechanism includes a pressing plate slidingly arranged inside the stirring cylinder and dividing the stirring cylinder into a first stirring chamber and a second stirring chamber. When the pressing plate is close to the bottom end of the stirring cylinder, the volume of the second stirring chamber decreases and the volume of the first stirring chamber increases. When the pressing plate is away from the bottom end of the stirring cylinder, the volume of the second stirring chamber increases and the volume of the first stirring chamber decreases. The stirring cylinder is embedded with a flow guide channel. The material passes through the flow guide channel and returns to the inside of the second stirring chamber, while the top layer of the original material in the first stirring chamber enters the bottom of the second stirring chamber. The above structure has low stirring efficiency and prolongs the production cycle, increases energy consumption and cost, which is not conducive to large-scale production and commercial application. Moreover, this equipment cannot effectively inject air evenly into the ice cream during stirring. Uniform air in the raw material not only gives the ice cream a light and dense texture, but also enhances its melting experience in the mouth. However, the air in the existing stirring equipment is often not evenly distributed in the ice cream, resulting in excessive air content in some areas (forming large ice crystals) and excessive tightness in other areas, lacking the desired fluffiness, and the resulting ice cream is often too thick and has poor taste.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the application.

[0028] Please refer to Figures 1-5A multi-layer segmented ice cream stirring device, comprising a stirring cavity 1, a stirring shaft, the stirring shaft is coaxially rotatably installed in the stirring cavity 1, the stirring shaft comprises a main stirring shaft 2 and an auxiliary stirring shaft 3, the main stirring shaft 2 and the auxiliary stirring shaft 3 are both in the same direction of the spiral shape, this design makes the main stirring shaft 2 in the rotating process, will produce a force along the spiral direction on the raw materials around the bottom, push the raw materials along the spiral direction of the main stirring shaft 2 to move upwards, promote the mutual contact and collision between the raw materials. At the same time, the auxiliary stirring shaft 3 is also spiral, but it is reversed, in order to push the raw materials from the top to the bottom, further mixing. The main stirring shaft 2 is sleeved with a main stirring cylinder 21, the auxiliary stirring shaft 3 is sleeved with an auxiliary stirring cylinder 31, the design of the main stirring cylinder 21 and the auxiliary stirring cylinder 31 increases the stirring area and stirring effect of the stirring device, so that the raw materials can be more fully stirred and mixed. The main stirring cylinder 21 and the auxiliary stirring cylinder 31 are connected by a feeding pipe 4 at the top, the design of the feeding pipe 4 makes the raw materials smoothly transfer from the top of the main stirring cylinder 21 to the auxiliary stirring cylinder 31, realizing the continuous stirring and mixing of the raw materials. The auxiliary stirring cylinder 31, the main stirring cylinder 21 and the stirring cavity 1 are in the form of planetary gear meshing, the main stirring cylinder 21 is the sun gear, the auxiliary stirring cylinder 31 is the planet wheel, and the stirring cavity 1 is the gear ring. The design of the planetary gear meshing makes the main stirring cylinder 21 and the auxiliary stirring cylinder 31 can drive and rotate each other, realizing more efficient stirring effect. This design can break the agglomeration and stratification phenomenon in the raw materials, and ensure the uniform distribution of the raw materials in the stirring cavity 1. The number of teeth of the main stirring cylinder 21 is greater than that of the auxiliary stirring cylinder 31, when the main stirring cylinder 21 rotates, it drives the auxiliary stirring cylinder 31 to rotate, and the rotating speed of the auxiliary stirring cylinder 31 is greater than that of the main stirring cylinder 21. The design that the number of teeth of the main stirring cylinder 21 is greater than that of the auxiliary stirring cylinder 31 makes the main stirring cylinder 21 rotate, which can drive the auxiliary stirring cylinder 31 to rotate at a faster speed. This design can improve the stirring efficiency and mixing effect of the stirring device, so that the raw materials can reach the state of uniform mixing more quickly. At the same time, different rotating speeds also promote the shearing and stretching effect between the raw materials, further improving the mixing quality. During the stirring process, the main stirring shaft 2 rotates forward and its own spiral structure produces an upward force on the raw materials, transporting the raw materials from the bottom to the top of the stirring cavity 1, while the auxiliary stirring shaft 3 reverses its own spiral structure to produce a downward force on the raw materials, transporting the raw materials transported to the top by the main stirring shaft 2 to the bottom again.

[0029] Please refer to Figures 4-6, the main stirring shaft 2 includes a transmission shaft 22, a spiral stirring disc 23, and a spiral aeration disc 24, the transmission shaft 22 penetrates through the bottom of the stirring cavity 1, and the bottom of the transmission shaft 22 is connected with a driving structure, the spiral stirring disc 23 and the spiral aeration disc 24 are coaxially installed on the transmission shaft 22, the spiral directions and the pitches of the spiral stirring disc 23 and the spiral aeration disc 24 are the same, and the spiral stirring disc 23 and the spiral aeration disc 24 are equidistantly installed along the axial direction of the transmission shaft 22, so that the raw materials can be subjected to uniform force during stirring, and the stirring efficiency is improved. The equidistant installation ensures that the raw materials are uniformly treated in the axial direction, and avoids the situation of excessive or insufficient local treatment. The transmission shaft 22 is provided with a gas-filled aeration cavity 221, the design of the aeration cavity 221 is to provide a gas source, the spiral aeration disc 24 is driven by periodic aeration, and then a vibration effect is generated, and the stirring effect is enhanced. The spiral aeration disc 24 includes an upper spiral disc 241 and a lower spiral disc 242, the upper spiral disc 241 and the lower spiral disc 242 are slidingly installed on the transmission shaft 22, the sliding installation allows the upper spiral disc 241 and the lower spiral disc 242 to freely move on the transmission shaft 22, so that periodic vibration and uniform gas penetration are realized. The transmission shaft 22 is provided with a gas groove 222 in communication with the aeration cavity 221, the design of the gas groove 222 is to guide the gas in the aeration cavity 221 into the cavity, and then to push the sliding of the upper spiral disc 241 and the lower spiral disc 242, so as to realize the vibration effect. The upper spiral disc 241 and the lower spiral disc 242 are provided with a cavity, the gas groove 222 is in communication with the cavity, and the upper spiral disc 241 and the lower spiral disc 242 are lifted and slid when the cavity is filled with gas. The communication design of the cavity and the gas groove 222 is a key structure for realizing the periodic sliding of the upper spiral disc 241 and the lower spiral disc 242, and the sliding and resetting are realized by the filling and releasing of the gas; the upper spiral disc 241 and the lower spiral disc 242 are provided with a gas filling hole 245 in communication with the cavity, the aeration cavity 221 is periodically filled with gas, and the upper spiral disc 241 and the lower spiral disc 242 are periodically slid to generate vibration; the spiral aeration disc 24 is sealingly connected with the main stirring cylinder 21, the sealing connection ensures that the gas will not leak from the gap between the spiral aeration disc 24 and the main stirring cylinder 21, ensures the effective use of the gas and the realization of the stirring effect. At the same time, it also avoids the raw materials entering the cavity or the aeration cavity 221, and ensures the stable operation of the device.

[0030] Please refer to Figures 4-7, the transmission shaft 22 is provided with a spiral chute 223, and the upper spiral disc 241 and the lower spiral disc 242 are slidingly installed in the spiral chute 223. This design allows the upper spiral disc 241 and the lower spiral disc 242 to freely slide in the spiral chute 223 of the transmission shaft 22, thereby realizing more complex stirring and aeration modes. The spiral chute 223 matches the spiral disc, which can ensure the continuity and uniformity of the stirring and aeration process. The spiral chute 223 is provided with a reset spring between the upper spiral disc 241 and the lower spiral disc 242, which pushes the upper spiral disc 241 and the lower spiral disc 242 to the middle position of the spiral chute 223. The design of the reset spring is to ensure that the upper spiral disc 241 and the lower spiral disc 242 can return to the initial position after sliding, that is, the middle position of the spiral chute 223. The reset spring is not shown. The upper spiral disc 241 and the lower spiral disc 242 are slidingly connected with a sector baffle 243. The sector baffle 243 is equidistantly arranged in two groups or more along the spiral direction. The sector baffle 243 is provided with a communication hole 244. When the sector baffle 243 slides to the outside, the communication hole 244 is communicated with the aeration hole 245. When the sector baffle 243 slides to the inside, the sector baffle 243 blocks the aeration hole 245 to close it. The sector baffle 243 is made of magnetic material, which can be iron alloy or the like. The inner wall of the spiral chute 223 is provided with two groups of adsorbing magnetic strips 224. The top magnetic pole of the upper adsorbing magnetic strip 224 is the same as that of the sector baffle 243, and the bottom magnetic pole of the upper adsorbing magnetic strip 224 is different from that of the sector baffle 243. The top magnetic pole of the lower adsorbing magnetic strip 224 is different from that of the sector baffle 243, and the bottom magnetic pole of the lower adsorbing magnetic strip 224 is the same as that of the sector baffle 243. By changing the positional relationship between the sector baffle 243 and the adsorbing magnetic strip 224, the position and motion trail of the sector baffle 243 in the spiral chute 223 can be controlled, thereby realizing more flexible stirring and aeration modes. When the cavity is filled with gas, the upper spiral disc 241 slides upward and drives the sector baffle 243 to move to the top of the adsorbing magnetic strip 224. The sector baffle 243 and the adsorbing magnetic strip 224 generate repulsion, the sector baffle 243 slides outward and makes the communication hole 244 communicated with the aeration hole 245, so that the gas in the cavity reduces the upper spiral disc 241 and drives the sector baffle 243 to slide to the lower end of the adsorbing magnetic strip 224. The adsorbing magnetic strip 224 adsorbs the sector baffle 243 to reset and close the aeration hole 245. The lower spiral disc 242 moves in the opposite direction of the upper spiral disc 241.

[0031] Please refer to Figures 1-7, the air groove 222 is spirally arranged. The spiral design of the air groove 222 is to better guide the gas in the air-filled cavity 221 into the cavity, thereby promoting the sliding of the upper spiral disc 241 and the lower spiral disc 242, achieving the vibration effect. This design ensures that the gas can uniformly and continuously act on the spiral air-filled disc 24, improving the efficiency of stirring and aeration. The auxiliary stirring shaft 3 is arranged in the circumferential direction of the main stirring shaft 2 in two or more groups. Designing two or more groups of auxiliary stirring shafts 3 can increase the stirring effect of the stirring device, so that the raw materials can be more fully stirred and mixed. Multiple groups of auxiliary stirring shafts 3 can form multiple stirring areas, improving the uniformity and efficiency of stirring. The helical pitch of the auxiliary stirring shaft 3 is a variable pitch, which gradually decreases from top to bottom. The design of the variable pitch makes the extrusion effect on the raw materials during stirring gradually increase, thereby further mixing the raw materials and uniformly distributing the bubbles. When the raw materials pass through the area with smaller helical pitch, their flow speed will be hindered, causing the raw materials to accumulate in this area and be subjected to greater pressure. This pressure effect causes large bubbles to be compressed, thereby breaking down into more small bubbles. And the gradually decreasing pitch can also make the raw materials gradually change direction and position during stirring, further improving the mixing efficiency. The diameter of the main stirring shaft 2 is larger than the diameter of the auxiliary stirring shaft 3, and the length of the main stirring cylinder 21 is longer than the length of the auxiliary stirring cylinder 31. The design of the main stirring shaft 2 with a larger diameter than the auxiliary stirring shaft 3 can produce greater stirring force and stirring area during stirring, thereby improving the stirring efficiency. The top cover 5 is assembled between the auxiliary stirring cylinder 31 and the material conveying pipe 4, the top cover 5 is rotatably connected with the auxiliary stirring cylinder 31, and the sealing cover 6 is arranged between the main stirring cylinder 21 and the material conveying pipe 4, the sealing cover 6 is rotatably connected with the main stirring cylinder 21. The bottom of the main stirring cylinder 21 and the auxiliary stirring cylinder 31 is in communication with the stirring cavity 1. The top end of the stirring cavity 1 is provided with a feeding port, the top of the main stirring cylinder 21 and the auxiliary stirring cylinder 31 is rotatably connected with a cylinder cover 7, the feeding port is arranged on the cylinder cover 7, and the bottom end of the stirring cavity 1 is provided with a discharging hole.

[0032] Working principle: use the device for ice cream raw materials for stirring. Raw materials from the top into the stirring chamber 1 feeding port, and start the drive structure driven shaft 22 rotation, because the main stirring cylinder 21 and auxiliary stirring cylinder 31 between the class planetary gear connection, when the main stirring cylinder 21 rotation will drive the surrounding other auxiliary stirring cylinder 31 together with rotation, and the main stirring cylinder 21 and auxiliary stirring cylinder 31 opposite direction, in the process, the auxiliary stirring cylinder 31 will drive the mixing chamber 1 in the raw materials, at the same time, due to the geometry of the spiral structure makes the main stirring shaft 2 in the rotation process, will produce a along the spiral direction of the force on the bottom of the raw materials, this force causes the raw materials along the spiral direction of the main stirring shaft 2 to be pushed to a higher position, when the raw materials along the spiral direction of the main stirring shaft 2 to move up, the raw materials will contact and collide with each other, at the same time, due to the rotation of the main stirring shaft 2, the raw materials will be subjected to shear and stretch, these can make the raw materials mixed. In addition, the spiral structure of the main stirring shaft 2 also makes the raw materials in the process of movement can change direction and position constantly, further promote the mixing, and when the raw materials movement to the main stirring shaft 2 top, will be along the feed pipe 4 into the auxiliary stirring cylinder 31, and auxiliary stirring shaft 3 is also spiral, but it is reversed. Therefore, when the raw materials from the main stirring shaft 2 top through the feed pipe 4 into the auxiliary stirring cylinder 31, the spiral structure of the auxiliary stirring shaft 3 will produce a downward push force on the raw materials, so that the raw materials along the spiral direction down, in the process of movement will also be subjected to auxiliary stirring shaft 3 spiral stirring gradually mixed.

[0033] In the process of stirring, because the main stirring shaft 2 is provided with spiral stirring disc 23 and spiral aeration disc 24, the two groups of structure can improve the fusion efficiency of raw materials on the main stirring shaft 2, and when the aeration cavity 221 is periodically filled with gas, can make the upper spiral disc 241 and lower spiral disc 242 reciprocating motion in order to realize the mixing effect of vibration of raw materials, greatly improve the mixing efficiency of raw materials in the main stirring shaft 2.

[0034] In the process of filling gas into the air cavity 221, the gas volume in the cavity increases, so the upper spiral disc 241 slides upward and drives the sector shutter 243 to move to the top of the adsorption magnetic strip 224. At this time, the sector shutter 243 and the adsorption magnetic strip 224 generate repulsion, so as to push the sector shutter 243 outward and make the communication hole 244 communicate with the air filling hole 245, so that the gas in the cavity decreases. With the gradual release of the gas in the cavity, the pressure decreases, and the upper spiral disc 241 is reset by the action of the return spring, so that the upper spiral disc 241 slides to the center position of the sliding groove 223 and resets. In the process of sliding down, the sector shutter 243 is adsorbed and reset by the adsorption magnetic strip 224, and the air filling hole 245 is closed. Subsequently, the gas in the cavity gradually increases and repeats the above movement. The lower spiral disc 242 and the upper spiral disc 241 move in the opposite direction. The upper spiral disc 241 and the lower spiral disc 242 repeat the above movement during the air filling process, not only can make the upper spiral disc 241 and the lower spiral disc 242 produce higher frequency vibration, but also can fill gas into the raw materials through the air filling hole 245. The air filling hole 245 is communicated with the communication hole 244 when the sector shutter 243 is pushed outward by repulsion, which makes the air filling process after the raw materials are extruded by the spiral stirring disc 23 and the spiral air filling disc 24. Because the spiral structure of the spiral air filling disc 24 produces a certain pressure on the raw materials, the gas can penetrate more uniformly into the raw materials. In addition, because the air filling process is a periodic operation of reciprocating cycle, the gas is not filled in a large amount at one time, but gradually and uniformly distributed in the raw materials, which further improves the uniformity of the gas. When the upper spiral disc 241 and the lower spiral disc 242 contract, the volume of the raw materials is also stretched. This extrusion and stretching process can decompose the large bubbles in the raw materials into more small bubbles. The formation of small bubbles increases the number of bubbles and reduces the volume of each bubble. Small bubbles are produced in stirring, so that the distribution of bubbles in the raw materials is more uniform and delicate. This dense bubble structure helps to improve the taste and texture of ice cream.

[0035] When the raw material enters the auxiliary stirring shaft 3 from the top of the main stirring shaft 2 through the feed pipe 4, the raw material has already been subjected to the spiral stirring and shock aeration of the main stirring shaft 2, forming a preliminary bubble distribution. However, some large bubbles are still contained in these bubbles. When the raw material enters the auxiliary stirring shaft 3 and moves downward along the spiral structure thereof, the extrusion effect on the raw material gradually increases due to the gradually decreasing spiral pitch. This extrusion effect not only helps the further mixing of the raw material, but also can extrude the residual large bubbles in the raw material into smaller bubbles. Specifically, when the raw material passes through the area with a smaller spiral pitch, the flow speed of the raw material is hindered, causing the raw material to accumulate in this area and be subjected to greater pressure. This pressure effect causes the large bubbles to be compressed, thereby breaking down into more small bubbles. At the same time, due to the continuous stirring process, these small bubbles are further uniformly distributed in the raw material. This dense bubble structure not only improves the taste and texture of the ice cream, but also makes the ice cream more delicate and smooth.

[0036] At the same time of the above stirring process, the auxiliary stirring cylinder 31 not only stirs and extrudes the raw material entering therein downward through its spiral structure, but also rotates and stirs the raw material in the stirring chamber 1 in the circumferential direction through its planetary gear meshing relationship with the main stirring cylinder 21 and the stirring chamber 1. This movement mode is not only limited to the auxiliary stirring cylinder 31 itself, but also drives the surrounding raw material in the stirring chamber 1 to mix in the circumferential direction through its rotation and movement. It can break the agglomeration and stratification of the raw material, and ensure that the raw material is uniformly distributed in the stirring chamber 1.
