[0001] This utility model relates to the technical field of beer processing equipment, specifically to an integrated machine for preparing milk foam draft beer. Background Technology

[0002] Existing beverages with milk foam typically have a layer of sweet, creamy foam on top, with a liquid beverage underneath. The milk foam, made from pure fresh milk and milk foam powder, has a certain thickness and requires refrigeration. The liquid beverage also usually needs to be refrigerated for preservation. This is especially true for new products like milk foam beer, where the bottom layer is an alcoholic beverage, such as a refreshing cream-flavored beer, where the bottom layer is draft beer, which even more necessitates refrigeration for preservation.

It is necessary to use separate draft beer machines and milk foam machines. However, existing draft beer machines and milk foam machines each have independent refrigeration systems and structures. Using two separate systems not only requires a large footprint and high energy consumption, but also makes subsequent maintenance inconvenient. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Please see Figures 1-6 This utility model provides a technical solution:

[0036] The integrated milk foam and draft beer preparation machine provided by this utility model includes a milk foam storage and preparation device, a draft beer storage and preparation device, and a cold storage chamber device for sealing the two. The milk foam storage and preparation device and the draft beer storage and preparation device are respectively provided with a cream outlet and a draft beer outlet, and the two are connected by a comprehensive connecting pipe. A horizontally arranged double material connector device is connected to the comprehensive connecting pipe.

[0037] like Figure 1 As shown, the dual-material connector device includes a transverse tubular body, and an infeed connector and an outlet regulating head device respectively connected to both ends of the transverse tubular body; the transverse tubular body serves as the skeleton of the entire device, used to connect and fix the various components of the infeed connector and the outlet regulating head device. Figure 2As shown, the transverse tubular main body houses the extrusion rod 9, which has a transverse beer inlet channel inside. This channel serves as a dedicated conveying path for draft beer. The transverse design of the channel adapts to the overall tubular structure, ensuring that the material flow direction is consistent with the main body of the device and reducing conveying resistance. Annular teeth are also provided on the outer wall of the left side of the extrusion rod 9. A matching cylindrical sleeve 7 is also fitted onto the outside of the left side of the extrusion rod 9. The annular gap between the annular teeth on the outer wall of the extrusion rod 9 and the inner wall of the cylindrical sleeve 7 forms a foaming pipe. When cream and air flow from the foaming inlet channel into the foaming pipe under negative pressure, the annular teeth on the outer wall of the extrusion rod 9 cut and agitate the fluid, ensuring thorough mixing of the material and air, while simultaneously creating turbulence to promote foam formation. The shape and distribution of the annular teeth can precisely control the agitation intensity, adapting to the foaming requirements of different materials. A fixed sleeve 6 is also fitted onto the outside of the cylindrical sleeve 7, with its two ends connected to the inlet connector and the outlet regulating head respectively. This ensures the overall stability of the dual-material connector device and the reliability of material conveying.

[0038] like Figure 2 As shown, the dispensing adjustment head device includes a dual-path adjustment guide seat 5. As the core component of the entire dispensing adjustment head device, the dual-path adjustment guide seat 5 is responsible for guiding the liquid flow and enabling function switching. The upper part of the dual-path adjustment guide seat 5 has a transverse through-hole. From right to left, vertically penetrating milk foam dispensing channel 10 and draft beer dispensing channel 12 are located at the bottom of the inner wall of the transverse through-hole. This clear spatial distribution achieves physical separation, ensuring that milk foam and draft beer flow through their respective dedicated channels before dispensing. Structurally, this avoids flavor mixing or contamination caused by path intersections, ensuring the purity of the beverage. Furthermore, the upper port of the milk foam dispensing channel 10 is lower than the upper port of the draft beer dispensing channel 12. This height difference between the dispensing channel ports matches the structure of the foaming channel and the beer inlet channel, ensuring their respective dispensing states and preventing mixing.

[0039] like Figure 2 and Figure 5As shown, the transverse through-hole at the upper end of the draft beer dispensing channel 12 is the first transverse channel, and the transverse through-hole at the upper end of the milk foam dispensing channel 10 is the second transverse channel. The inner diameter of the second transverse channel is larger than that of the first transverse channel. The core differences between milk foam and draft beer lie in their foam content, flowability, and sensitivity to the channel: milk foam contains a large amount of fine foam, is lightweight, and easily broken by pressure. Therefore, the second transverse channel uses a relatively larger inner diameter to reduce resistance during transverse flow, preventing the foam from being crushed by the channel wall and thus preserving its fluffy texture. While draft beer also contains foam, it relies more on a stable flow rate and pressure to maintain its flavor compared to milk foam. Therefore, the smaller inner diameter of the first transverse channel allows for more precise control of the draft beer's flow rate, preventing excessively fast flow, foam overflow, or a thinner taste due to an overly wide channel.

[0040] like Figure 2 and Figure 4 As shown, a horizontally arranged cocktail piping 2 is installed within the first transverse channel. The side wall of the cocktail piping 2 has an inlet hole that matches the upper port of the draft beer dispensing channel 12, providing an independent access path for draft beer. This allows draft beer entering the cocktail piping 2 from the inlet channel to precisely enter the draft beer dispensing channel 12 through this hole, ensuring stable draft beer delivery and preventing cross-mixing with milk foam within the pipe. The cocktail piping 2 extends into the inner left end of the foaming channel. Between the annular toothed channel of the foaming channel, the right end of the first connecting block 4, and the outer wall of the cocktail piping 2, there is a milk foam input channel 14 that connects to the upper port of the milk foam dispensing channel 10 in the second transverse channel. The left end of the foaming pipe in the milk foam storage and preparation equipment is sealed to the right end of the cocktail piping 2, ensuring that the milk foam dispensing channel 10 and the draft beer dispensing channel 12 form independent delivery paths. The sealed design ensures no leakage of milk foam and prevents contact with the outside environment or the draft beer path, guaranteeing its purity and foaming state. The left end of the cocktail mixing pipe 2 passes through a transverse through hole and has a transverse liquor passage plug 1 that matches the inner wall of the pipe. This plug is used to control the opening and closing of the liquor inlet. The left end of the transverse liquor passage plug 1 is connected to the dispensing lever 3, which is an operating component. By manually controlling its movement, the dispensing lever 3 controls the transverse liquor passage plug 1 to move left and right in the cocktail mixing pipe 2. When the transverse liquor passage plug 1 moves to the leftmost end, the liquor inlet on the cocktail mixing pipe 2 is opened. When the transverse liquor passage plug 1 does not move, the liquor inlet on the cocktail mixing pipe 2 is sealed and blocked by the transverse liquor passage plug 1, thus realizing the start and stop of the dispensing operation.

[0041] A first connecting block 4 is fitted around the outside of the dual-channel adjusting guide seat 5, and the right end of the first connecting block 4 extends into the fixed sleeve 6 and is sealed and fixedly connected to the outer wall of the left end of the cylindrical sleeve 7. This is used to realize the structural connection and fixation between the dual-channel adjusting guide seat 5, the cylindrical sleeve 7, and the fixed sleeve 6, and the sealed and fixed connection method can further prevent fluid leakage.

[0042] like Figure 1 As shown, the feeding connector device serves as an integrated connecting component for the inlet and foaming materials, integrating the inlet channel and the foaming channel to achieve orderly input and transmission of the liquor and foaming raw materials. Specifically, it includes a second connector 8 sleeved on the outer right side of the inlet channel. The second connector 8 has a third transverse channel in its middle that matches the outer wall of the right end of the extrusion rod 9. The right end of the extrusion rod 9 passes through the second connector 8. The inner left wall of the third transverse channel of the second connector 8 is an outwardly expanding conical through-hole. The right end of the fixing sleeve 6 extends into the conical through-hole on the left side of the third transverse channel, and its outer wall abuts against the conical through-hole, sealing it to ensure the airtightness of the liquor transmission and prevent leakage. Furthermore, a vertical foaming feed channel, connected to the foaming channel, is located at the bottom left side of the second connector 8. This vertical foaming feed channel serves as the channel for foaming raw materials (such as cream) to enter the device, communicating with the foaming channel and providing a raw material transport path for milk foam generation. Figure 3 As shown, a one-way valve 13 for the cream inlet is also connected to the vertical foaming feed channel. This valve controls the unidirectional entry of foaming ingredients such as cream into the system, preventing backflow and ensuring the stability and purity of the foaming process. A negative pressure device is also installed at the cream inlet valve 13. This device generates negative pressure to facilitate the smooth entry of foaming ingredients such as cream into the vertical foaming feed channel, enhancing the feeding power and ensuring a stable and continuous delivery of the foaming ingredients to the foaming system. Simultaneously, the one-way valve prevents backflow under negative pressure, further ensuring the reliability of the feeding process. A milk foam embossing head 11 is also connected to the bottom of the dual-channel regulating guide seat 5, used to shape or emboss the generated milk foam, improving the appearance and texture of the beverage.

[0043] like Figure 6 As shown, the draft beer dispensing channel 12 is located in the middle of the dual-channel regulating guide seat 5 and has a circular cross-section. As the final output channel for draft beer, the circular cross-section adapts to the flow characteristics of the beer, ensuring smooth dispensing. The milk foam dispensing channel 10 is located to the right of the draft beer dispensing channel 12 and has a pea-shaped flat oval cross-section. This is used to adapt to the viscosity characteristics of milk foam, facilitating stable milk foam output. The flat oval cross-section can also work with the draft beer dispensing to create a layered or mixed effect, optimizing the beverage's presentation.

[0044] The working principle of this integrated milk foam and draft beer preparation machine is as follows:

[0045] The milk foam storage and preparation equipment and the draft beer storage and preparation equipment in the milk foam draft beer preparation machine respectively provide cream raw materials and draft beer liquid. When draft beer needs to be prepared: the draft beer liquid is first transported to the mixing pipeline 2 through the horizontal beer inlet channel inside the extrusion rod 9. At this time, by controlling the beer dispensing rocker 3, the horizontal beer channel plug 1 can be moved left and right in the mixing pipeline 2. When the plug moves to the leftmost end, the beer inlet hole on the mixing pipeline 2 is opened, and the draft beer enters the draft beer outlet channel 12 on the dual-passage regulating guide seat 5 through the outlet. Since the draft beer outlet channel 12 is located in the middle of the guide seat and has a circular cross-section, it is adapted to the flow characteristics of the beer liquid, and finally the draft beer is smoothly output along the channel.

[0046] When milk foam needs to be prepared: the one-way valve 13 of the cream inlet pipe controls the one-way entry of cream raw materials and air. The vacuum suction device assists in enhancing the feeding power. Under the action of the vacuum suction device, the cream raw materials and air are transported to the vertical foaming feed channel, so that the cream enters the foaming channel formed by the annular teeth of the extrusion rod 9 and the cylindrical sleeve 7. When the cream raw materials flow through the foaming channel, the annular teeth will cut and disturb the fluid, so that the cream and air are fully mixed and turbulent, thereby generating fine milk foam. The milk foam then enters the milk foam outlet channel 10 on the dual-channel regulating guide seat 5 through the milk foam inlet channel 14. Because the cross-section of this channel is pea-shaped and flat, it is suitable for the viscous characteristics of milk foam and can prevent the milk foam from breaking. Finally, the milk foam is output along this channel. If it is necessary to improve the appearance, the milk foam embossing head 11 at the bottom of the dual-channel regulating guide seat 5 can shape or emboss the milk foam.

[0047] Throughout the process, the dual-channel regulating guide seat 5 separates the milk foam outlet channel 10 and the draft beer outlet channel 12, structurally preventing the two materials from mixing and ensuring the purity of the beverage. At the same time, the fixed sleeve 6 and the first connecting block 4 and other components are sealed to fix each structure, ensuring no leakage during the material conveying process, and ultimately achieving stable preparation and output of milk foam and draft beer.

[0048] In summary, this utility model of an integrated milk foam and draft beer preparation machine features a simple and ingenious structure. It integrates the preparation and storage functions of milk foam and draft beer through a dual-material connector, enabling simultaneous output of chilled beer and cream foam from a single outlet. This solves the problems of traditional separation equipment, such as large footprint, high energy consumption, and inconvenient maintenance, thus improving the efficiency of making alcoholic beverages with milk foam. Simultaneously, the differentiated design of the discharge channels in the dual-material connector ensures beverage layering and taste, while the mixing pipeline, combined with plugs, enables convenient control. The sealing structure and one-way valve enhance stability and sealing while reducing cold loss, and the milk foam embossing head enhances visual appeal. These multi-dimensional optimizations improve the overall performance of the equipment.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
