Description

Technical Field

[0001] This utility model relates to a cold drink processing equipment, and in particular to an ice cream machine material cylinder assembly and an ice cream machine. Background Technology

[0002] In the field of food processing machinery technology, especially in the field of frozen beverage processing equipment, the ice sponge machine is a key piece of equipment for producing frozen drinks with a soft texture and delicate taste, such as ice sponge and soft-serve ice cream. It mainly undertakes functions such as material carrying, mixing, auxiliary refrigeration, and guiding the discharge. It needs to meet requirements such as high material homogeneity, stable refrigeration efficiency, and continuous and controllable discharge. In existing technologies, ice sponge machines often suffer from problems such as uneven material texture, unstable discharge, and material accumulation inside the machine. Utility Model Content

[0003] Based on this, this application provides a material cylinder assembly for an ice cream machine, which improves the flow of materials inside the ice cream machine and ensures stable output speed and quality.

[0004] A first aspect of this application provides an ice cream machine cylinder assembly, the ice cream machine cylinder assembly comprising:

[0005] The material cylinder shell includes a stirring chamber and a discharge port communicating with the stirring chamber. It also has an installation port located at both ends of the stirring chamber, for mounting a refrigeration stirring assembly. A first guide member is disposed on the material cylinder shell and located within the stirring chamber, situated on the side where the discharge port is located. A second guide member is disposed on the material cylinder assembly, with an arc-shaped guide surface facing the stirring chamber, also situated on the side where the installation port is located. A portion of the material cylinder shell with the discharge port forms a guide plane, opposite to the installation port, with the discharge port and the first guide member located on either side of the guide plane.

[0006] The aforementioned ice cream machine cylinder assembly features a guide plane that serves as a flat structure on the discharge port side of the cylinder shell. This guide plane structure reduces material diversion along the inner wall of the cylinder shell during output, preventing uncontrollable discharge pressure. Simultaneously, as the material moves towards this area under the action of the refrigeration and stirring components, the planar structure prevents material jamming caused by unevenness or abrupt changes in curvature of the inner wall, guiding the material to slide along the plane towards the discharge port. This increases the pressure at the discharge port, creating an aggregation effect and preventing problems such as interrupted discharge, gushing, or clumping blockage. It also reduces turbulence near the discharge port, resulting in a more stable material supply during discharge. The first guide component forms a diversion barrier on the discharge port side, redirecting material that did not enter the discharge port and accumulated in the upper part of the stirring chamber back to the middle of the stirring chamber, forming cross-convection with the material from the installation port. Based on the guiding effect of the first guide component, the second guide component further guides the material tangentially towards the center of the mixing chamber through a smooth, curved transition of its arc-shaped guide surface. This prevents material from accumulating or forming dead zones in the gap between the refrigeration mixing components and the material cylinder shell, allowing the material to participate more smoothly in the overall mixing cycle. The first and second guide components together create a dual-guide channel within the chamber. This efficient flow path increases the number of times the material participates in the mixing cycle per unit time, not only shortening the overall mixing and refrigeration time but also ensuring continuous contact between the material and the refrigeration components during the cycle. This prevents localized overcooling or freezing caused by excessive residence time, ultimately improving the uniformity of the ice cream product and production efficiency.

[0007] In one embodiment, the end of the second guide member away from the barrel shell is an arc-shaped surface, and the area between the end of the second guide member away from the barrel shell and the barrel shell is a guide ramp. The guide ramp and the arc-shaped surface cooperate to form the arc-shaped guide surface. The smooth transition of the arc-shaped surface can disperse the impact force when the material moves towards the second guide member, avoiding material rebound or local accumulation caused by the angular structure, and allowing the material to change its direction of movement more smoothly along the curved surface. The curvature design of the arc-shaped surface can adapt to the material circulation path in the mixing chamber, allowing the material near the guide member to flow naturally towards the center of the mixing chamber, reducing the material's retention near the second guide member, ensuring that the material continuously participates in the mixing cycle, and further improving the uniformity of material mixing. The inclined structure of the guide ramp can utilize gravity and the material's own kinetic energy to guide the material to move along the ramp towards the center of the mixing chamber, avoiding the formation of material accumulation. The design of the arc-shaped surface without dead corners and the inclination angle of the guide ramp can reduce material residue, reduce cleaning difficulty, and ensure hygiene and safety in food processing and other scenarios. The arc-shaped guide surface allows the material to undergo a continuous process of buffering, turning, and guiding when it comes into contact with the second guide component. The continuous guiding path avoids abrupt changes in the direction of material movement, reduces energy loss, and enables the material to participate in the circulation with higher efficiency, thereby shortening the overall stirring and cooling time.

[0008] In one embodiment, the second flow guide is provided with a buffer chamber, and the second flow guide has a liquid outlet communicating with the buffer chamber, the liquid outlet being located at the guide slope. The buffer chamber provides temporary storage space for subsequent material addition, while the liquid outlet allows for precise addition into the mixing chamber. The liquid outlet being located on the guide slope allows the material to diffuse rapidly along the slope, avoiding the problems of excessively high local concentrations or uneven mixing caused by traditional single-point injection.

[0009] In one embodiment, the second flow guide is integrally formed with the barrel shell. Through this integral forming process, the second flow guide and the barrel shell form a complete, rigid whole, without any seams or connecting parts. This allows for more even distribution of the impact and pressure generated during high-speed mixing and flow of materials within the mixing chamber, ensuring the second flow guide maintains a stable position and shape during long-term use and guaranteeing the reliable performance of its flow guiding function. Simultaneously, the seamless, integrated structure reduces material residue and cleaning dead zones, meeting stringent food production standards. It also reduces the number of molds and processing steps in production, eliminates assembly processes, significantly improves production efficiency, reduces production costs, and facilitates large-scale mass production.

[0010] In one embodiment, the second flow guide includes a flow guide bottom wall, flow guide side walls, and an arc-shaped guide wall. The flow guide bottom wall is disposed on the material cylinder shell and is inclined relative to the material cylinder shell. The flow guide bottom wall has a guide slope. There are two flow guide side walls, which are disposed on the flow guide bottom wall and the material cylinder shell, located on opposite sides of the flow guide bottom wall. The arc-shaped guide wall is disposed on the flow guide bottom wall and the flow guide side walls, located on the side of the flow guide bottom wall away from the material cylinder shell. The guide slope of the flow guide bottom wall guides the material towards the center of the mixing chamber or the outlet side through its inclination angle. The flow guide side walls on both sides restrict the lateral diffusion of the material, confining it within the flow channel formed by the bottom wall and the arc-shaped guide wall, ensuring that the material flows in a concentrated direction. This constraint allows the material to form a higher flow velocity and concentration when it flows through the outlet into the mixing chamber. When subjected to material impact, the curved surface design of the arc-shaped guide wall decomposes the impact force into tangential force along the wall surface and pressure perpendicular to the wall surface. The tangential force is jointly borne by the bottom wall and the side wall of the guide, avoiding deformation or breakage caused by excessive local stress and extending the service life of the second guide component.

[0011] In one embodiment, the second guide member further includes a side baffle. The bottom wall, side wall, and arc-shaped guide wall cooperate to form a buffer cavity. The bottom wall has an outlet communicating with the buffer cavity. The side baffle is disposed on the side wall and arc-shaped guide wall and is arranged along the circumference of the buffer cavity. The side baffle is located at the opening of the buffer cavity. The enclosure structure of the three walls creates a relatively independent space for the buffer cavity, which can buffer the material when it enters and then accurately deliver it into the mixing chamber through the outlet. This avoids the material being directly poured into the material flow of the mixing chamber, which would cause splashing and loss due to impact. It also reduces the risk of external impurities entering the mixing chamber and contaminating the material. The side baffle connects with the arc-shaped guide wall and the side wall to form a continuous curved transition, providing a clear flow boundary for the material near the opening of the buffer cavity and preventing material turbulence caused by structural abrupt changes at the opening. During the mixing process, the material in the mixing chamber may flow back towards the opening of the buffer cavity due to eddies or impacts. The side baffle, as a physical barrier, can effectively prevent the material from overflowing.

[0012] In one embodiment, the first guide member extends along the width direction of the material cylinder shell and is inclined. By extending along the width direction of the material cylinder shell and spanning the entire guide plane, the first guide member provides uniform flow guidance for materials within a wide range, preventing localized material accumulation due to insufficient coverage. This ensures that materials at different width positions within the mixing chamber flow along a preset path, improving the overall flow order. The inclined angle design guides the material to flow downwards in a uniform direction, causing it to gather towards the outlet. Simultaneously, the material moves obliquely towards the outlet, increasing the contact time and frequency with the refrigeration and mixing components, allowing for more thorough cooling and mixing, further improving the fineness and cooling uniformity of the ice cream product.

[0013] In one embodiment, the first flow guide is integrally formed with the barrel shell. This one-piece molding process creates a seamless, monolithic structure, which evenly distributes the stress generated by material impact throughout the barrel shell, avoiding the localized stress concentration problems that can occur with separate connections and extending the component's lifespan. Simultaneously, the transition surface between the first flow guide and the barrel shell is smooth and continuous, without any seams, facilitating easy removal of residual material. For ice cream machines used in food processing, this design effectively reduces hygiene risks and meets stringent food production standards.

[0014] In one embodiment, the ice cream machine's feed cylinder assembly further includes a third guide member, which is disposed on the feed cylinder housing and located on the side wall of the housing. The third guide member is connected to the first guide member. The third guide member guides the material near the side wall, pushing it away from the side wall and into the main material flow. Simultaneously, it guides this material into the effective range of the first guide member, allowing it to participate in the flow towards the discharge port, thereby reducing material retention on the side wall. The connection and fixation of the third guide member to the first guide member on the feed cylinder housing better disperses stress, reduces the load on individual guide members, and improves the overall durability and service life of the feed cylinder assembly.

[0015] In one embodiment, the barrel shell includes a barrel body and an end cap. One end of the barrel body has an assembly port, and the other end of the barrel body away from the assembly port has a discharge port. The end cap is disposed on the barrel body and covers the assembly port. The end cap and the barrel body cooperate to form the stirring chamber. The end cap has an installation port. A first flow guide is disposed on the barrel body, and a second flow guide is disposed on the end cap. By separating the barrel body and the end cap, the forming process of the stirring chamber is decomposed into the processing and assembly of two independent components, significantly reducing the overall forming difficulty. For the installation of core components such as the refrigeration stirring assembly, the installation port on the end cap can be operated separately in the later stages of assembly, simplifying the assembly steps. The two flow guides are respectively disposed on the barrel body and the end cap. This two-end distribution allows the two flow guides to function at key points in the material flow, forming a closed-loop flow guide through the stirring chamber. This ensures that the material is precisely guided from entering the stirring area to being discharged, improving the overall stirring and refrigeration efficiency. By removing the end cap to directly expose the assembly port, maintenance can be performed on the inside of the mixing chamber or the refrigeration mixing component without disassembling the entire barrel shell, greatly reducing the difficulty of maintenance.

[0016] In one embodiment, the barrel body includes a barrel body, a discharge shell, and reinforcing ribs. The barrel body and the end cap cooperate to form the stirring chamber. The barrel body has a discharge port. The discharge shell is disposed on the barrel body and has an installation cavity that communicates with the discharge port. It also includes a discharge control handle disposed on the discharge shell and located at the installation cavity. The discharge control handle can open or close the discharge port. The reinforcing ribs are disposed on the barrel body and the discharge shell, and are located at the connection between the barrel body and the discharge shell. The discharge shell has an independent space with an internal installation cavity connected to the discharge port, physically separating the material conveying and stirring spaces, thus avoiding interference from vibration and pressure during stirring on the discharge system. The independent space of the installation cavity provides sufficient movement margin for the discharge control handle, enabling precise control of the discharge port through rotation, pressing, etc., maintaining stable sealing performance, and meeting the adjustment needs of different discharge volumes. The reinforcing ribs increase the wall thickness and contact area at the connection between the barrel shell and the discharge shell, distributing stress over a wider area and preventing problems such as shell cracking and material leakage from gaps after long-term use.

[0017] In one embodiment, the barrel body further includes two fastening members disposed on the barrel body, located on opposite sides of the barrel body. These fastening members engage with locking components. The engagement of the fastening members and locking components enables quick connection, allowing for the assembly or disassembly of the barrel shell and related components without the need for tools, significantly improving the efficiency of equipment assembly, maintenance, and cleaning.

[0018] In one embodiment, the barrel body has a feed inlet, which is opposite to the second guide member. The second guide member has a buffer chamber and a liquid outlet communicating with the buffer chamber. It also includes a cover plate, which is rotatably mounted on the barrel body and can open or close the feed inlet. By having the feed inlet opposite to the second guide member, material enters the buffer chamber of the second guide member through the feed inlet for temporary storage, avoiding material splashing caused by direct feeding into the high-speed rotating stirring assembly, thus preventing material waste and increasing the difficulty of cleaning the chamber. The buffer chamber, as a temporary storage space, supports intermittent feeding, eliminating the need for continuous manual operation at the feed inlet and greatly improving work efficiency. The cover plate creates a relatively closed chamber structure in the buffer chamber, reducing the evaporation or leakage of material within the buffer chamber and preventing material from splashing out of the feed inlet during stirring.

[0019] In one embodiment, the first flow guide is integrally formed with the material cylinder body. The integral forming process creates a rigid whole between the first flow guide and the material cylinder body, with a smooth transition at the connection surface. There are no protrusions, depressions, or gaps caused by splicing, reducing turbulence or eddies caused by structural abrupt changes, lowering flow resistance, preventing material from accumulating in gaps, and ensuring the cleanliness of the cavity after each processing, meeting the hygiene requirements for food-grade ice cream production.

[0020] In one embodiment, the second flow guide is integrally formed with the end cap. This integral forming evenly distributes the impact force generated by the material during stirring and the vibration stress of the refrigeration stirring component throughout the end cap, preventing localized stress concentration and deformation of the second flow guide. The integral forming, manufactured using precision molds, strictly ensures the relative positional accuracy of each structure of the second flow guide with the end cap, avoiding localized accumulation or flow turbulence caused by structural deviations, thus guaranteeing uniform stirring and stable discharge. The integrated structure is easy to assemble and disassemble, convenient for cleaning, and avoids material accumulation and retention at the joints between separate parts, meeting the hygiene requirements for food-grade ice cream production.

[0039] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0041] The following describes an ice cream machine cylinder assembly according to some embodiments of the present invention with reference to the accompanying drawings.

[0042] Example 1

[0043] like Figures 1 to 10As shown, this embodiment discloses a material cylinder assembly for an ice cream machine, including a material cylinder shell 1. The material cylinder shell 1 has a stirring chamber 101, a discharge port 102 communicating with the stirring chamber, and a mounting port 103. The discharge port 102 and the mounting port 103 are located at opposite ends of the stirring chamber 101, and the mounting port 103 is used to install a refrigeration stirring assembly. A first guide member 2 is disposed on the material cylinder shell 1 and located in the stirring chamber 101, on the side where the discharge port 102 is located. A second guide member 3 is disposed on the material cylinder assembly 1, with an arc-shaped guide surface 301 on the side facing the stirring chamber 101, and the second guide member 3 is located on the side where the mounting port 103 is located. The material cylinder shell 1 has a discharge port 102 on one side, which is a guide plane 1101. The guide plane 1101 is opposite to the mounting port 103. The two sides of the guide plane 1101 are the discharge port 102 and the first guide member 2, respectively.

[0044] In the aforementioned ice cream machine cylinder assembly, the guide plane 1101 serves as a flat structure on one side of the outlet 102 of the cylinder shell 1. The guide plane 1101 structure reduces material diversion along the inner wall of the cylinder shell 1 during output, preventing uncontrollable output pressure at the outlet 102. Simultaneously, when material moves towards this area under the action of the refrigeration stirring assembly, the planar structure prevents material jamming caused by unevenness or abrupt changes in curvature of the inner wall, guiding the material to slide along the plane towards the outlet 102, increasing the pressure at the outlet 102, creating an aggregation effect, and preventing problems such as interrupted discharge, gushing, or clumping blockage. It also reduces turbulence near the outlet, making the material supply more stable during discharge. The first guide member 2 forms a diversion barrier on the outlet 102 side, redirecting material that did not enter the outlet and accumulated in the upper part of the stirring chamber 101 back to the middle of the stirring chamber, forming cross-flow with material from the mounting port 103. Based on the guiding effect of the first guide component 2, the second guide component 3 further guides the material tangentially towards the center of the mixing chamber 101 through the smooth curved transition of the arc-shaped guide surface 301. This prevents the material from accumulating or forming vortex dead zones in the gap between the refrigeration mixing component and the material cylinder shell 1, allowing the material to participate more smoothly in the overall mixing cycle. The first guide component 2 and the second guide component 3 construct a dual-guide channel inside the chamber. The efficient flow path increases the number of times the material participates in the mixing cycle per unit time, which not only shortens the overall mixing and refrigeration time but also allows the material to continuously contact the refrigeration component during the circulation process, avoiding local overcooling or freezing caused by excessive residence time. Ultimately, this improves the texture uniformity and production efficiency of the ice cotton product.

[0045] like Figure 2 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further defines the end of the second guide member 3 away from the barrel shell 1 as an arc-shaped surface 3011, and the area between the end of the second guide member 3 away from the barrel shell 1 and the barrel shell 1 as a guide slope 3012. The guide slope 3012 and the arc-shaped surface 3011 cooperate to form an arc-shaped guide surface 301. The smooth transition of the arc-shaped surface 3011 can disperse the impact force when the material moves towards the second guide member 3, avoid material rebound or local accumulation caused by the angular structure, and allow the material to change its direction of movement more smoothly along the curved surface. The curvature design of the arc-shaped surface 3011 can adapt to the material circulation path in the mixing chamber 101, so that the material near the guide member can be naturally guided to the middle of the mixing chamber 101, reducing the retention of material near the second guide member 3, ensuring that the material continuously participates in the mixing cycle, and further improving the uniformity of material mixing. The inclined structure of the guide ramp 3012 utilizes gravity and the material's own kinetic energy to guide the material along the ramp towards the center of the mixing chamber 101, preventing material accumulation. The arc-shaped surface 3011's design without dead angles and the inclined angle of the guide ramp 3012 reduce material residue, lower cleaning difficulty, and ensure hygiene and safety in food processing and other scenarios. The arc-shaped guide surface 301 allows the material to undergo a continuous process of buffering, turning, and guiding when it comes into contact with the second guide component 3. The continuous guiding path avoids abrupt changes in the material's movement direction, reduces energy loss, and allows the material to participate in the circulation more efficiently, thereby shortening the overall mixing and cooling time.

[0046] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second guide member 3 is provided with a buffer cavity 302, and the second guide member 3 has a liquid outlet 303 communicating with the buffer cavity 302, the liquid outlet 303 being located at the guide slope 3012. The buffer cavity 302 can provide temporary storage space for materials to be added later, and the liquid outlet 303 can be accurately added into the stirring chamber 101. The liquid outlet 303 is located at the guide slope 3012, and the material can quickly diffuse along the material flowing along the slope, avoiding the problems of excessively high local concentration or uneven mixing caused by traditional single-point injection.

[0047] like Figure 2 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further defines that the second guide member 3 and the barrel shell 1 are integrally formed. Through the integral forming process, the second guide member 3 and the barrel shell 1 form a complete rigid whole, without splicing gaps or connecting parts. This allows for more uniform bearing of the impact and pressure generated when the material is stirred and flowed at high speed in the mixing chamber 101, ensuring that the second guide member 3 maintains a stable position and shape during long-term use and guaranteeing the reliable performance of its guiding function. At the same time, the integrated structure without dead corners reduces material residue and cleaning dead corners, meeting the strict standards of food production; it reduces the number of molds and processing steps in production, eliminates the assembly process, significantly improves production efficiency, reduces production costs, and is more conducive to achieving large-scale mass production.

[0048] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines the second guide member 3 as including a guide bottom wall 311, a guide side wall 312, and an arc-shaped guide wall 313. The guide bottom wall 311 is disposed on the material cylinder shell 1 and is inclined relative to the material cylinder shell 1. The guide bottom wall 311 is provided with a guide slope 3012. There are two guide side walls 312, which are disposed on the guide bottom wall 311 and the material cylinder shell 1, and are located on both sides of the guide bottom wall 311. The arc-shaped guide wall 313 is disposed on the guide bottom wall 311 and the guide side wall 312, and is located on the side of the guide bottom wall 311 away from the material cylinder shell 1. Through the guide slope 3012 of the guide bottom wall 311, its inclination angle guides the material to move towards the middle of the stirring chamber 101 or the discharge port 102. The guide sidewalls 312 on both sides restrict the lateral diffusion of the material, confining it within the guide channel formed by the bottom wall and the arc-shaped guide wall 313, ensuring that the material flows in a concentrated manner along a preset direction. This constraint allows the material to achieve a higher flow velocity and concentration when it flows through the outlet 303 into the stirring chamber 101. The curved surface design of the arc-shaped guide wall 313 decomposes the impact force into a tangential force along the wall surface and a pressure perpendicular to the wall surface when impacted by the material. The tangential force is jointly absorbed by the guide bottom wall 311 and the guide sidewalls 312, avoiding deformation or breakage caused by excessive local stress and extending the service life of the second guide component 3.

[0049] like Figure 4As shown, in addition to the features of the above embodiments, this embodiment further specifies that the second guide member 3 also includes a side baffle 314. The guide bottom wall 311, the guide side wall 312, and the arc-shaped guide wall 313 cooperate to form a buffer cavity 302. The guide bottom wall 311 has a liquid outlet 303 communicating with the buffer cavity 302. The side baffle 314 is disposed on the guide side wall 312 and the arc-shaped guide wall 313 and is arranged along the circumference of the buffer cavity 302. The side baffle 314 is located at the opening of the buffer cavity 302. The enclosure structure of the three walls makes the buffer cavity 302 form a relatively independent space, which can buffer the material when it enters, and then accurately deliver it into the stirring chamber 101 through the liquid outlet 303. This avoids the material being directly poured into the material flow of the stirring chamber 101, which would cause the material to splash and be lost due to impact. It also reduces the risk of external impurities entering the stirring chamber 101 and contaminating the material. The side baffle 314 connects with the arc-shaped guide wall 313 and the flow-guiding sidewall 312 to form a continuous curved transition, providing a clear flow boundary for the material near the opening of the buffer chamber 302 and preventing material turbulence caused by structural abrupt changes at the opening. During the stirring process, the material in the stirring chamber 101 may flow back towards the opening of the buffer chamber 302 due to eddies or impacts. The side baffle 314, as a physical barrier, can effectively prevent material overflow.

[0050] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines the first guide member 2 as extending along the width direction of the barrel shell 1, and the first guide member 2 is inclined. By extending along the width direction of the barrel shell 1 and spanning the entire guide plane 1101, the first guide member 2 forms a uniform guiding effect on the material within a wide range, avoiding localized material accumulation due to insufficient coverage of the guide member, ensuring that materials at different width positions within the mixing chamber 101 can flow along a preset path, and improving the overall flow orderliness. The inclined angle design guides the material to flow downwards in a uniform direction, causing the material to gather towards the outlet 102. Simultaneously, the material moves obliquely as it flows towards the outlet 102, increasing the contact time and frequency with the refrigeration and stirring components, allowing the material to be more fully cooled and stirred, further improving the fineness and cooling uniformity of the ice cream product.

[0051] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that the first guide member 2 and the barrel shell 1 are integrally formed. The seamless integral structure formed by the integral molding process can evenly distribute the stress generated by the material impact throughout the barrel shell 1, avoiding the local stress concentration problem that may occur with split connections and extending the service life of the components. At the same time, the transition surface between the first guide member 2 and the barrel shell 1 is smooth and continuous, without any splicing gaps, facilitating easy removal of residual material. For ice cream machines used in food processing, this design effectively reduces hygiene risks and meets the stringent standards of food production.

[0052] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the ice cream machine cylinder assembly also includes a third guide member 4. The third guide member 4 is disposed on the cylinder housing 1 and located on the side wall of the cylinder housing 1, and is connected to the first guide member 2. The third guide member 4 can guide the material near the side wall, pushing it away from the side wall and into the mainstream material flow. At the same time, it guides these materials to the effective range of the first guide member 2, allowing them to participate in the flow process towards the discharge port 102, thereby reducing the retention of material on the side wall. The third guide member 4 is connected to and fixed to the first guide member 2 on the cylinder housing 1, which can better distribute stress, reduce the stress burden on a single guide member, and improve the overall durability and service life of the cylinder assembly.

[0053] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines the barrel shell 1 as including a barrel body 11 and an end cap 12. One end of the barrel body 11 has an assembly port 104, and the other end of the barrel body 11 away from the assembly port 104 has a discharge port 102. The end cap 12 is disposed on the barrel body 11 and covers the assembly port 104. The end cap 12 and the barrel body 11 cooperate to form a stirring chamber 101. The end cap 12 has an installation port 103. A first guide member 2 is disposed on the barrel body 11, and a second guide member 3 is disposed on the end cap 12. Through the separate design of the barrel body 11 and the end cap 12, the forming process of the stirring chamber 101 is decomposed into the processing and assembly of two independent components, significantly reducing the overall forming difficulty. For the installation of core components such as the refrigeration stirring assembly, the installation port 103 on the end cap 12 can be operated separately in the later stages of assembly, simplifying the assembly steps. Two guide vanes are respectively located on the barrel body 11 and the end cap 12. This dual-end distribution allows the two guide vanes to function at key points in the material flow, forming a closed-loop flow guide through the mixing chamber 101. This ensures precise guidance of the material from its entry into the mixing zone to its discharge, improving overall mixing and cooling efficiency. Maintenance of the mixing chamber 101 or the cooling mixing assembly can be performed directly by removing the end cap 12 to expose the assembly port 104, eliminating the need for complete disassembly of the barrel body 1 and significantly reducing maintenance difficulty.

[0054] like Figures 7 to 9As shown, in addition to the features of the above embodiments, this embodiment further defines the barrel body 11 as including a barrel body 111, a discharge shell 112, and a reinforcing rib 113. The barrel body 111 and the end cap 12 cooperate to form a stirring chamber 101. The barrel body 111 has a discharge port 102. The discharge shell 112 is disposed on the barrel body 111 and has an installation cavity 105. The installation cavity 105 communicates with the discharge port 102. It also includes a discharge control handle 5. The discharge control handle 5 is disposed on the discharge shell 112 and located at the location of the installation cavity 105. The discharge control handle 5 can open or close the discharge port 102. The reinforcing rib 113 is disposed on the barrel body 111 and the discharge shell 112 and is located at the connection between the barrel body 111 and the discharge shell 112. The discharge shell 112 has an independent space with an internal mounting cavity 105 connected to the discharge port 102. This physically separates the material conveying and mixing spaces, preventing vibration and pressure during mixing from interfering with the discharge system. The independent space of the mounting cavity 105 provides ample room for movement for the discharge control handle 5, allowing for precise control of the discharge port 102 through rotation, pressing, etc., maintaining stable sealing performance and meeting the adjustment needs of different discharge volumes. The reinforcing ribs increase the wall thickness and contact area at the connection between the barrel body 111 and the discharge shell 112, distributing stress over a wider area and preventing problems such as shell cracking and material leakage from gaps after long-term use.

[0055] like Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the barrel body 11 also includes a fastening member 114. The fastening member 114 is disposed on the barrel body 111, and there are two fastening members 114 located on both sides of the barrel body 111. The fastening member 114 is used to cooperate with the locking member. Through the cooperation of the fastening member 114 and the locking member, a quick connection can be achieved, and the assembly or disassembly of the barrel body 111 and related components can be completed without the need for tools, which greatly improves the efficiency of equipment assembly, maintenance and cleaning.

[0056] like Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that the barrel body 111 has a feed inlet 106, which is disposed opposite to the second guide member 3. The second guide member 3 has a buffer chamber 302 and a liquid outlet 303 communicating with the buffer chamber 302. It also includes a cover plate 6, which is rotatably disposed on the barrel body 111 and can open or close the feed inlet 106. By having the feed inlet 106 disposed opposite to the second guide member 3, the material enters the buffer chamber 302 of the second guide member through the feed inlet 106 and is temporarily stored there. This avoids material splashing caused by direct feeding of the high-speed rotating stirring component, which would result in material waste and increase the difficulty of cleaning the chamber. The buffer chamber 302 serves as a temporary storage space, supporting intermittent feeding, eliminating the need for continuous manual operation at the feed inlet 106, and greatly improving work efficiency. The cover plate 6 makes the buffer chamber 302 form a relatively closed cavity structure, reducing the volatilization or leakage of materials in the buffer chamber 302 and preventing materials from splashing out of the feed port 106 during the stirring process.

[0057] like Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines that the first guide member 2 and the material cylinder body 111 are integrally formed. The integral forming process makes the first guide member 2 and the material cylinder body 111 form a rigid whole, with a smooth transition at the connection surface. There are no protrusions, depressions, or gaps caused by splicing, reducing turbulence or eddies caused by structural abrupt changes, lowering flow resistance, preventing material from accumulating in gaps, and ensuring the cleanliness of the cavity after each processing, meeting the hygiene requirements for food-grade ice cream production.

[0058] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that the second guide member 3 and the end cap 12 are integrally formed. Through integral forming, the impact force generated by the material during stirring and the vibration stress of the refrigeration stirring component are evenly distributed throughout the end cap 12, avoiding deformation caused by localized stress concentration in the second guide member 3. The integral forming, manufactured using precision molds, can strictly guarantee the relative positional accuracy of each structure of the second guide member 3 and the end cap 12, avoiding localized accumulation or flow disturbance caused by structural deviations, thereby ensuring uniform stirring and stable discharge. The integrated structure is easy to assemble and disassemble, convenient for cleaning, and avoids material accumulation and retention at the joints between separate parts, meeting the hygiene requirements for food-grade ice cream production.
