[0002] In beer production, there are extremely strict requirements for the dissolved oxygen and microbial content in process water. If the process water used for foaming contains oxygen, it will accelerate beer oxidation, produce unpleasant flavors, and affect quality. If it contains microorganisms, it will lead to product spoilage. Existing deoxygenation methods mainly include thermal deoxygenation, vacuum deoxygenation, and chemical deoxygenation. However, these methods have drawbacks such as high energy consumption, complex equipment, or the introduction of chemical residues. Sterilization methods mainly include pasteurization, ultraviolet sterilization, and chemical sterilization. However, these methods also have drawbacks such as altering the properties of the liquid, leaving chemical residues, or incomplete sterilization, which leads to a decrease in the efficiency of deoxygenation and sterilization.

[0019] Reference Figures 1-5 An ultrasonic deoxygenation and sterilization device for beer foaming includes two sets of spaced-apart first processing tanks 1 and second processing tanks 2. Both the first processing tanks 1 and the second processing tanks 2 are gourd-shaped structures with interconnected contraction and expansion chambers. When beer flows through the contraction chamber, the cross-sectional area decreases, thereby increasing the flow rate and reducing the pressure, which promotes the rapid precipitation of dissolved oxygen to form microbubbles. A storage tank 3 is provided on the side of the second processing tank 2 away from the first processing tank 1. The first processing tank 1 is used to receive externally input beer liquid, perform preliminary treatment, and transport it to the second processing tank 2 for further treatment, and finally transport it to the storage tank 3. The first processing tank 1 has a first liquid inlet 11 at its bottom, which is connected to the outside via a pipe. The top of the first processing tank 1 has a first liquid outlet 12 connected to a first liquid outlet pipe. One end of the first liquid outlet pipe is connected to the second liquid inlet 21 at the bottom of the second processing tank 2. The top of the second processing tank 2 has a second liquid outlet 22 connected to a second liquid outlet pipe. One end of the second liquid outlet pipe is connected to the storage tank 3, allowing beer to fill the processing tank from bottom to top, completely covering the contraction chamber, expansion chamber, and transducer probe 41, preventing short-circuit flow and ensuring that every drop of beer undergoes foaming and ultrasonic treatment. The first processing tank 1, the second processing tank 2, the first liquid outlet pipe, and the second liquid outlet pipe are all made of food-grade stainless steel. Food-grade stainless steel is chemically stable, does not leach heavy metals, and has a smooth surface that is not prone to bacterial growth, meeting the safety standards for food contact materials. It also includes two sets of spaced ultrasonic generators 4. Both sets of ultrasonic generators 4 have transducer probes 41 and are located in the expansion chambers provided in the first processing tank 1 and the second processing tank 2. The expansion chamber is the bubble residence area. The probes directly act on the dense bubble area, maximizing the utilization of the cavitation effect. The transducer probes 41 emit high-frequency vibrations that act on the suspended bubbles in the expansion chamber. The bubbles expand and burst rapidly, instantly generating high temperature and high pressure of hundreds of atmospheres, directly killing bacteria, while accelerating the separation of oxygen and beer in the bubbles. Both the first and second outlet pipes are equipped with water pumps 5. The top of the storage tank 3 is provided with an injection port 31 for injecting inert gas. Nitrogen can be used as the inert gas to provide continuous power for the beer flow. The flow rate of the pipeline is controlled to ensure that the residence time of the beer in the processing tank meets the requirements for deoxygenation and sterilization. This avoids insufficient processing due to excessive flow rate or bubble aggregation and escape due to excessively slow flow rate. Nitrogen is an inert gas and does not react with beer. It is injected into the storage tank 3 through the injection port 31 to expel the air in the tank and form a nitrogen atmosphere in the storage tank 3, preventing the processed beer from re-inhaling oxygen.

[0020] Based on the above structure, beer is transported through pipelines to the expansion chamber of the first processing tank 1. By activating the ultrasonic generator 4, the transducer probe 41 emits high-frequency vibrations that act on the suspended bubbles in the expansion chamber, accelerating the separation of oxygen from the beer in the bubbles. As the amount of beer increases, the beer that has undergone the foaming operation is gradually pushed into the contraction chamber. With the cooperation of the water pump 5, the liquid is transported to the second processing tank 2. The second processing tank 2 also has an ultrasonic generator 4, which can perform a second foaming, deoxygenation, and sterilization operation on the beer. Finally, the beer that has undergone the two operations is transported to the storage tank 3, and inert gas is injected through the gas injection port 31 to prevent the beer from absorbing oxygen again after processing. Through the double foaming and inert gas protection, the beer can achieve sterilization and deoxygenation effects, ensuring the quality of the beer.

[0021] The device also includes a host computer, which is connected to the ultrasonic generator 4, water pump 5, flow meter 6, pressure gauge 7 and drive motor 811, thereby enabling the interconnection of multiple components.

[0022] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The first processing tank 1 is provided with several spaced partition plates 13. The partition plates 13 are all located in the expansion cavity and are spaced along the length of the processing tank. The partition plates 13 divide the expansion cavity into multiple independent flow channels. Each of the partition plates 13 has several evenly distributed overflow holes 131. Through the cooperation of the overflow holes 131, the partition plates 13 are interconnected. The first liquid outlet pipe is located in the contraction chamber. Beer needs to penetrate layer by layer through the overflow holes 131, forcibly prolonging the residence time in the expansion chamber, slowing down the flow rate in the expansion chamber, and allowing the bubbles to suspend and stay, making full contact with the ultrasonic transducer probe 41. The cavitation effect directly acts on the bubbles and the surrounding beer.

[0023] In one embodiment, reference is made to Figures 1-3 The first outlet pipe is also equipped with a flow meter component 6 and a pressure gauge component 7. The flow meter component 6 is located between the water pump component 5 and the pressure gauge component 7. The flow meter component 6 collects beer flow rate data in real time, and the pressure gauge component 7 monitors the pipeline system pressure. The signals from both are linked and fed back to the water pump control terminal. It can dynamically adjust the water pump power according to the optimal parameters of ultrasonic action to maintain pipeline flow rate and stabilize pressure. When the flow rate is too fast, the power is reduced to avoid insufficient processing time. When the flow rate is too slow, the power is increased to prevent bubble aggregation and escape. At the same time, it is convenient for process parameter traceability and optimization.

[0024] In one embodiment, reference is made to Figure 1 The second processing tank 2 is equipped with a feeding pipe 23. One end of the feeding pipe 23 is located inside the second processing tank 2, and the other end is located outside the second processing tank 2 and is hinged to a cover plate 231. By rotating the cover plate 231, the cover plate 231 can cover or move away from the opening of the feeding pipe 23. When the cover plate 231 is closed, the feeding pipe 23 forms a sealed structure to ensure the inert gas inside the second processing tank 2. When process aids such as antioxidants or clarifying agents need to be added, the cover plate 231 can be opened to quickly feed the materials. The cover plate is closed immediately after feeding to avoid damaging the inert environment inside the tank.

[0025] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 The second processing tank 2 is also equipped with a stirring component 8. The stirring flow field covers the entire expansion cavity, thereby eliminating processing dead zones. The stirring component 8 includes a rotating shaft 81, which is located inside the expansion cavity of the second processing tank 2. A bearing is provided at the connection between one end of the rotating shaft 81 and the inner wall of the second processing tank 2. The other end of the rotating shaft 81 extends to the outside of the second processing tank 2 and is connected to a drive motor 811 through a coupling. The drive motor 811 adopts the servo drive motor 811 in the prior art. A roller 82 is sleeved on the rotating shaft 81. Stirring rods 821 are evenly distributed on the outer circumference of the roller 82. Through the cooperation of the drive motor 811 and the rotating shaft 81, the roller 82 can drive the stirring rods 821 to rotate in a circle. The servo motor drives the stirring rods 821 to rotate in a circle, forming a radial stirring flow field, breaking the laminar flow state of the beer, and making the beer fully mixed with the transducer probe 41.

[0026] In one embodiment, reference is made to Figure 1 and Figure 2 Both the first processing tank 1 and the second processing tank 2 are equipped with support frames at the bottom. When they are on the same horizontal plane, the second processing tank 2 is at a higher height than the first processing tank 1, forming a stepped distribution between the two tanks. This utilizes gravitational potential energy to assist in liquid transport, forming a dual-drive mode of gravity power with the water pump 5, reducing the power load on the water pump. Furthermore, the stepped distribution causes the pipeline to transport liquid at an incline, avoiding dead corners caused by pipeline bends and reducing the risk of bacterial growth. At the same time, the beer experiences slight pressure changes due to the height difference during flow, further enhancing the foaming effect.

[0027] In one embodiment, reference is made to Figure 2 and Figure 5 The storage tank 3 has an inclined end 32 inside and a groove is formed. The storage tank 3 is equipped with a drain pipe at the groove. The processed beer needs to be temporarily stored in the storage tank 3. The inclined end 32 uses gravity to guide the liquid to converge to the groove, forming a centralized drain channel to avoid liquid residue at the bottom of the storage tank 3 due to the flat design. At the same time, the drain pipe at the groove can be completely emptied, which is convenient for subsequent cleaning and maintenance.
