[0053] Example 1
[0054] The preparation of oxygen-carrying nano bubble water adopts the three-stage nano oxygen injection system of the present invention, and the specific steps are as follows:
[0055] The water source input unit provides initial pure water, which is connected to the pretreatment module to filter and dechlorinate the water and adjust the temperature to 25°C.
[0056] The Venturi oxygen injection device uses the Venturi effect to introduce high-purity oxygen into flowing water, controls the Venturi oxygen injection rate, and completes primary mixing and coarse oxygen injection.
[0057] The gas-liquid mixture enters the high-pressure homogenization module and undergoes high-pressure shearing at a pressure of 80MPa, which refines the gas-liquid mixture to the micron level, achieving secondary crushing and homogenization.
[0058] Entering the ultrasonic nano-crystallization module, three-level ultrasonic oscillation treatment is performed at a frequency of 60kHz to further nano-crystallize the bubbles.
[0059] The nano-sized bubble water is introduced into the bubble stabilization tank, and the static pressure and slow flow principles are used to maintain the suspension and uniform distribution of bubbles. It is then left to absorb for 30 minutes.
[0060] The quality detection module is equipped with a dissolved oxygen concentration analyzer, a particle size detector and other equipment to achieve online quality monitoring. The dissolved oxygen content is detected to be 45 mg / L and the bubble particle size is within the range of 10 to 100 nm.

[0062] Example 2
[0063] The preparation of oxygen-carrying nano bubble water adopts the three-stage nano oxygen injection system of the present invention, and the specific steps are as follows:
[0064] The water source input unit provides initial pure water, which is connected to the pretreatment module to filter and dechlorinate the water and adjust the temperature to 20°C.
[0065] The Venturi oxygen injection device uses the Venturi effect to introduce high-purity oxygen into flowing water, controls the Venturi oxygen injection rate, and completes primary mixing and coarse oxygen injection.
[0066] The gas-liquid mixture enters the high-pressure homogenization module and undergoes high-pressure shearing at a pressure of 100 MPa, which refines the gas-liquid mixture to the micron level, achieving secondary crushing and homogenization.
[0067] Entering the ultrasonic nano-crystallization module, three-level ultrasonic oscillation treatment is performed at a frequency of 80kHz to further nano-crystallize the bubbles.
[0068] The nano-sized bubble water is introduced into the bubble stabilization tank, and the static pressure and slow flow principles are used to maintain the suspension and uniform distribution of bubbles. It is then left to absorb for 25 minutes.
[0069] The quality detection module is equipped with a dissolved oxygen concentration analyzer, a particle size detector and other equipment to achieve online quality monitoring. The dissolved oxygen content is detected to be 55 mg / L and the bubble particle size is within the range of 10 to 100 nm.
[0070] After meeting the standards, the qualified sparkling water is quantitatively packaged into finished product containers through the filling output module.
[0071] This invention aims to produce oxygen-carrying nanobubble water with high stability, high oxygen content, and controllable particle size. The currently proposed "three-stage nano-oxygen injection system" solution is the optimal integrated approach. However, in theory, there are several alternative technical solutions, which differ from the present invention in terms of effectiveness, stability, and cost controllability:
[0072] Two-stage oxygen injection system (excluding ultrasonic module): This system uses only two-stage oxygen injection technology (Venturi + high-pressure homogenization), which can improve bubble refinement to a certain extent. However, due to the lack of the third stage of particle size reduction (ultrasonic shearing), the particle size distribution is unstable and difficult to effectively control at the nanometer level. This makes bubble agglomeration and oxygen escape more likely. While the equipment is relatively low in cost, the bubble size is mostly 0.3 to 5 microns, and the upper limit of oxygen solubility is limited (approximately 10 to 15 mg / L), making it unsuitable for high-end product scenarios.
[0073] Plasma bubble activation: Low-temperature plasma is used to activate oxygen and water, forming microbubble clusters and promoting the formation of free radical structures. This method theoretically improves solubility and bubble encapsulation. However, due to potential free radical side reactions, high safety control costs, and complex electric field structures, it has only been explored in small quantities in laboratories or medical applications. High costs, complex equipment, and difficult process control make it difficult to achieve stable, large-scale continuous production, posing food contact safety risks.
[0074] Chemical oxygen carrier solution method (such as hydrogen peroxide additives): This method increases oxygen levels by adding a small amount of chemical oxygen carriers, such as diluted H2O2 or magnesium oxide, to drinking water. While this method is effective in increasing oxygen concentration quickly, it does not conform to the concept of "purely physical preparation" for healthy drinking water and may not be approved for food-grade drinking or for the consumer market due to chemical residue issues. High oxygen concentrations and the risk of additive residues make it unsuitable for long-term drinking or the high-end drinking water market.
[0075] Mechanical gas-liquid agitation or cyclone mixing: Oxygen is introduced into the water through strong agitation or a cyclone injector. This method has a simple structure and is suitable for industrial cooling water and fishery oxygenation. However, it cannot effectively refine bubbles to the nanometer level and has low oxygen utilization efficiency, making it unsuitable for producing food-grade sparkling water. Low cost, large particle size, and low oxygen retention rate result in failure to meet industry standards for oxygen-carrying water.
[0076] While several alternative solutions exist, none can match the "three-stage nano-oxygen injection system" proposed in this invention in achieving nanoparticle size control, high dissolved oxygen concentration, food-grade safety, and continuous production capabilities. Therefore, the technical solution of this invention possesses innovative advantages and represents the most optimized integrated solution available.
[0077] This invention improves oxygen solubility and dissolution efficiency. Existing oxygen water technologies often use high-pressure or bubble injection, but these methods have limited efficiency and stability in dissolving oxygen. This invention utilizes a three-stage nano-oxygen injection system and a step-by-step dissolution technique. Each stage of the equipment refines the bubbles in a different way, maximizing oxygen solubility. This three-stage dissolution process significantly increases the oxygen dissolution efficiency of the product compared to traditional methods, ensuring that oxygen is fully dissolved in the water.
[0078] The present invention ensures stable oxygen dissolution and sustained release. Traditional oxygen dissolution in water is often affected by the size and stability of bubbles, resulting in a short period of stability in water. The present invention's three-stage nano-oxygen injection system precisely controls the size and distribution of bubbles, ensuring a long-term, stable oxygen presence in water. Nanobubble technology improves bubble stability and ensures sustained oxygen release in water, ensuring a continuous oxygen supply after consumption and preventing oxygen escape.
[0079] This invention simplifies the production process and reduces production costs. Traditional oxygen water production typically requires complex, high-pressure equipment, which is costly and unsuitable for large-scale production. The three-stage nano-oxygen injection system of this invention optimizes bubble generation technology and employs a multi-stage dissolution process, eliminating the need for high-pressure equipment and simplifying the production process. This system not only significantly reduces production costs but also improves production efficiency, making it suitable for large-scale industrial production.
[0080] This invention enhances the product's health benefits and market competitiveness. The oxygen-carrying nanobubble water not only provides efficient oxygen dissolution but also helps promote exercise recovery, boost immunity, and enhance antioxidant function. Through its three-stage nano-oxygen injection system, the product provides consumers with more efficient oxygen supplementation and possesses significant health benefits, meeting the needs of athletes, fitness enthusiasts, the elderly, and others for healthy drinks. This will enhance the product's market competitiveness and enable it to gain a foothold in the functional beverage market.
[0081] The present invention offers the flexibility to adapt to diverse application scenarios. The three-stage nano-oxygen injection system is highly adaptable and flexible, enabling customized production based on diverse needs. In diverse application scenarios (such as sports recovery, anti-aging, and daily health management), the system can be adjusted based on bubble dissolution requirements, ensuring optimal results for each application scenario.
[0082] This invention promotes environmental protection and sustainable development. The production process does not rely on complex chemical additives or high-pressure equipment, reducing energy consumption and equipment investment. By optimizing the bubble generation and dissolution processes, the system is more environmentally friendly and meets modern society's requirements for green environmental protection and sustainable development.
[0083] In summary, the three-stage nano-oxygen injection system and its preparation method utilize innovative multi-stage bubble dissolution technology to significantly improve the solubility and stability of oxygen in water, resolving issues such as low dissolution efficiency and unstable bubbles in traditional oxygen water technologies. By simplifying the production process and reducing production costs, this invention can be widely applied in the production of healthy beverages, meeting consumer demand for efficient oxygen supplementation and health benefits, and possesses broad market prospects and excellent commercial value.
