Description

Technical Field

[0001] The invention relates to the technical field of carbonated beverage production, in particular to a novel and efficient Venturi medium-temperature gas mixing system for carbonated beverages. Background Art

[0002] Carbonated beverages are beverages that achieve a bubbling effect by infusing them with carbon dioxide or other gases. In industrial production, carbon dioxide is typically dissolved in the beverage under high pressure in a supersaturated state. This carbonation process is primarily achieved by passing carbon dioxide bubbles through the beverage liquid. During this process, the gas transfers mass to the liquid through the bubble surfaces, and the dissolved carbon dioxide reacts with water to form carbonic acid. Currently, the carbon dioxide filling process in the production of most carbonated beverages is based on the Venturi effect.

[0003] The basic principle of the Venturi effect is that when a confined fluid passes through a reduced diameter pipe, the fluid velocity increases. According to Bernoulli's principle, this increased velocity causes a decrease in pressure, forming a negative pressure zone at the point where the pipe diameter is smallest. Leveraging this characteristic, carbon dioxide gas is drawn into the beverage under external pressure, achieving carbonation. However, most Venturi-effect-based mixers and carbonators currently on the market simply apply this basic principle, lacking in-depth research and optimized design of the Venturi tube's structural parameters (such as cross-sectional ratio and inlet and outlet pressures).

[0004] A prominent issue with existing technology is that traditional Venturi carbonators require low temperatures (typically 1-4°C) to achieve optimal carbonation. This results in the widespread use of low-temperature mixing solutions in commercial mixers, while subsequent processes require product heating (bottle / can warming). This cooling-then-heating process not only increases equipment investment and floor space, but also results in significant energy waste. According to industry statistics, energy consumption during bottle / can warming accounts for approximately 15%-20% of the total energy consumption of the entire production line.

[0005] In addition, traditional Venturi carbonators have the following technical drawbacks: (1) insufficient uniformity in gas-liquid mixing, resulting in unstable product quality; (2) large pressure losses, which increase pumping energy consumption; and (3) sensitivity to changes in operating conditions and poor adaptability. These issues have seriously restricted improvements in energy efficiency and product quality in carbonated beverage production. No solutions have yet been proposed for these technical issues. Summary of the Invention

[0006] In response to the problems in the related technology, the present invention proposes a new and efficient Venturi medium-temperature mixing system for carbonated beverages to overcome the above-mentioned technical problems existing in the existing related technology. The purpose of the present invention is to have efficient mixing performance and significantly improve energy saving effects. The three-dimensional simulation subsystem can accurately predict operating parameters through CFD simulation to reduce errors. The data acquisition subsystem monitors key parameters in real time to ensure process stability. The energy-saving evaluation subsystem automatically generates evaluation reports, provides energy efficiency optimization suggestions, improves carbon dioxide utilization, and provides real-time data tracking and abnormal warnings to ensure production safety, facilitate maintenance, and extend service life.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] (1) The present invention is a novel and efficient medium-temperature Venturi gas mixing system for carbonated beverages. By setting a gas mixing device, the structure of the connection between the throat pipe and the front fluid inlet pipe and the rear stabilizing pipe is optimized. At the connection between the throat pipe and the fluid inlet pipe, and the throat pipe and the stabilizing pipe, no gently inclined transition section is set, which causes a sharp change in the radial dimension. At the same time, the pipe diameter ratio and the air hole position are finely optimized. After the material is pressurized by the booster pump, it will produce a stronger turbulent effect when passing through the throat pipe, and the critical pressure difference is reduced as much as possible to achieve the cold boiling effect of the material. Cold boiling essentially refers to the boiling phenomenon of liquid material under non-heating conditions. At this time, the liquid quickly changes from liquid to gas in a very short time, and then condenses. The carbon dioxide gas is mixed with the gaseous liquid product, ensuring the combination with the mass transfer surface at the molecular level. The mass transfer surface is 10,000 times greater than that of traditional Venturi tubes and vortex technologies. The mixed gas solution of carbon dioxide and gaseous products is condensed after carbonation in the carbonator, where the carbon dioxide is completely dissolved under specific process parameters. When leaving the new carbonator, the carbonation efficiency reaches the physically feasible maximum value (efficiency coefficient >97%) and is close to the theoretical value predicted by Henry's law. The gas-liquid mixing uniformity reaches 95%±2%, which is significantly better than the 85%-90% level of traditional equipment. The design of four radially evenly distributed air holes forms a stable vortex structure. The ratio of vortex intensity to mainstream flow velocity is optimized to 1:1.2-1.5, ensuring that the carbon dioxide is fully dissolved. The optimized design of the diffuser enables a kinetic energy recovery efficiency of 85%-90%, and a pressure loss of ≤0.12MPa, which is 15%-20% lower than that of traditional equipment.

[0029] (2) The present invention is a novel and efficient Venturi medium-temperature gas mixing system for carbonated beverages. By setting up a three-dimensional simulation subsystem and performing CFD simulation (inlet flow rate 10-15 m / s, pressure 0.3-0.6 MPa), the operating parameters can be accurately predicted with an error control within ±5%. The data acquisition subsystem monitors key parameters (flow rate, pressure, gas solubility) in real time to ensure process stability. The energy-saving evaluation subsystem automatically generates an evaluation report and provides energy efficiency optimization suggestions, which improves the carbon dioxide utilization rate by 30%-35%. The system is made of 316L stainless steel and has a performance degradation of <2% after 1000 hours of continuous operation in an acidic environment of 80°C and pH 3-4. The remote monitoring subsystem realizes real-time data tracking and abnormal warning to ensure production safety. The modular design is adopted for easy maintenance, and the service life of key components is extended by more than 30%. The carbon dioxide utilization rate is increased by 30%-35%, greenhouse gas emissions are reduced, no refrigerant is required, and the use of ozone-depleting substances is avoided.

[0035] Example

[0036] See also Figure 1-2 The present invention proposes a novel and efficient medium-temperature Venturi gas mixing system for carbonated beverages. The novel and efficient medium-temperature Venturi gas mixing system for carbonated beverages comprises:

[0037] The gas mixing device includes a fluid inlet pipe 1, a throat pipe 2, a stabilizing pipe 3, a diffuser 4, and a fluid outlet pipe 5 that share a common center line. The fluid inlet pipe 1, the throat pipe 2, the stabilizing pipe 3, and the fluid outlet pipe 5 are all cylindrical pipes of uniform size. The diffuser 4 is a trumpet-shaped structure with a radial size gradually increasing from the stabilizing pipe 3 to the fluid outlet pipe 5. The radial size of the throat pipe 2 is smaller than that of the fluid inlet pipe 1 and the stabilizing pipe 3. The connecting sections of the throat pipe 2 and the fluid inlet pipe 1, as well as the throat pipe 2 and the stabilizing pipe 3, are all at 90 degrees to the center line.

[0038] The throat pipe 2 and the fluid inlet pipe 1 are covered with a sanitary pipe 6 on the outside to form a closed air cavity 7. Four radially evenly distributed air holes 8 are opened on the side of the throat pipe 2. The air cavity 7 and the air holes 8 are connected. An air inlet port 9 is provided on the outside of the sanitary pipe 6.

[0043] Furthermore, the data acquisition subsystem includes:

[0067] Furthermore, the diameter of the throat pipe 2 is 7-12 mm, the diameter of the stabilizing tube 3 is 12-18 mm, the aspect ratio of the stabilizing tube 3 is 12-18, the air hole 8 is opened at a position 2-3 mm from the entrance of the throat pipe 2, the aperture of the air hole 8 is 4-6 mm, and the gradual expansion angle of the diffuser 4 is 35°-43°.

[0068] In this embodiment, the above parameters of the new high-efficiency Venturi unit are the optimal area ratios obtained after multiple calculations and simulations, including the determination of the inlet pressure. The product pressure P1 required at the inlet of the new high-efficiency Venturi unit is greater than 9 bar, which requires an additional booster pump to achieve.

[0069] The working principle of the gas mixing device is:

[0070] The liquid material is pressurized by the booster pump and flows into the fluid inlet pipe 1 and finally flows out of the fluid outlet pipe 5. Figure 2 As shown, P1 is the inlet pressure at the front end of the fluid inlet pipe 1, P2 is the outlet pressure at the rear end of the fluid outlet pipe 5, and P3 is the pressure of the air cavity 7. The pressure difference between P1 and P2 when P3 is zero is the critical pressure difference. The size of the critical pressure difference affects the start time of carbonation of the Venturi unit, so while increasing the pressure difference between the fluid inlet pipe 1 and the fluid outlet pipe 5, the critical pressure difference should be reduced as much as possible.

[0071] Furthermore, the predicted data output by the three-dimensional simulation subsystem showed that under the operating pressure of 0.3-0.6MPa, the gas-liquid mixing uniformity reached 95%±2%, and the pressure loss was ≤0.12MPa.

[0072] Furthermore, the evaluation report generated by the energy-saving evaluation subsystem shows that the mixing system saves 18%-25% energy compared with traditional mixing devices under the same operating conditions, and the carbon dioxide utilization rate is increased by 30%-35%.

[0073] Furthermore, it also includes a remote monitoring subsystem for real-time display and storage of operating data collected by the data acquisition subsystem, and transmission to the user terminal via the network.

[0074] Furthermore, the remote monitoring subsystem also includes an early warning module, which automatically sends an early warning message to the user terminal when it detects that the operating parameters exceed the preset range.

[0075] Furthermore, the gas mixing device is made of 316L stainless steel, and durability test data shows that after 1,000 hours of continuous operation in an acidic environment of 80°C and pH 3-4, the performance degradation is less than 2%.

[0076] In this embodiment, the fluid inlet pipe 1 is directly reduced in diameter to form a throat pipe 2, and a conventional tapered pipe is used for transition. When the liquid material passes through the throat pipe 2, the radial dimension changes dramatically, and the liquid material generates maximum turbulence. In addition, various parameters of the Venturi medium-temperature mixing device for carbonated beverages are optimized to make the critical pressure difference as low as possible, thereby achieving a cold boiling effect of the material.

[0077] Cold boiling is essentially the boiling of a liquid material without heating, where the liquid changes its aggregate state to a gaseous state in a very short time at ambient temperature and then immediately condenses. The carbon dioxide gas is mixed with the liquid product in a gaseous state, thereby ensuring bonding with the mass transfer surface at the molecular level. The mass transfer surface is 10,000 times larger than other technologies such as traditional venturi tubes and vortexes. The mixed gas solution of carbon dioxide and gaseous product is carbonated in the carbonator and condensed, where the carbon dioxide is completely dissolved under the given process parameters and leaves the new carbonator. The effectiveness of carbonation reaches its physically feasible maximum value (efficiency coefficient>97%) and is close to the theoretical value derived from Henry's law.

[0078] The throat pipe 2 of this embodiment solves the problem in the prior art that the gas mixing device does not inhale or inhales little gas when the liquid flow rate is low. This function is relatively easy to achieve according to the Bernoulli equation, and can be achieved by increasing the cross-sectional ratio of the inlet pipe and the throat pipe.

[0079] The purpose of this embodiment to change the structure and shape of the traditional Venturi tube is not only to allow air to flow, but also to achieve maximum turbulence and the lowest possible critical pressure difference, thereby achieving a cold boiling effect on the material and allowing the product to be mixed at a molecular level. There is a stable phase interface between the two fluids in contact with each other, and there is a very thin fluid film layer on both sides of the interface. The solute passes through this double membrane layer in the form of molecular diffusion. There is no mass transfer resistance at the phase interface, that is, the concentration of the solute at the phase interface is in a phase equilibrium state. In the two-phase mainstream area outside the membrane layer, the mass transfer resistance can be ignored due to the high mass transfer rate, and the interphase mass transfer resistance is concentrated in the two membrane layers.

[0080] In the present invention, the three-dimensional simulation subsystem uses SolidWorks to establish a parametric three-dimensional model, which is then imported into ANSYS Meshing to divide the mesh. The simulation parameters of the three-dimensional simulation subsystem are:

[0081]
