Embodiment 1

[0024] Pass pure water through the pipe port at the bottom of the container until it fills the entire reaction container and covers the hydrogen production unit. The liquid enters from the porous membrane at the bottom of the hydrogen production unit and reacts to generate hydrogen under the action of the ring electrode. At this time, the temperature is controlled at 0°C; When a large amount of hydrogen is enriched and passes through the nanoporous metal membrane on the side of the microreactor (aperture 200 nm; θ = 45°), the ring electrode is closed, and the broadband ultrasonic generator (20KHz low frequency 5 min; 400KHz high frequency 15 min) The liquid mixing system causes linear oscillation and cavitation effects, thereby forming interfacial hydrogen nanobubbles (~300 nm) and gradually transforming into bulk hydrogen nanobubbles (~50 nm); ultrasonic cavitation and the energy release of part of the bubble rupture and microjet flow The effect completes the rapid sterilizati...

[0026] Pass mineral water through the pipe port at the bottom of the container until it fills the entire reaction container and covers the hydrogen production unit. The liquid enters from the porous membrane at the bottom of the hydrogen production unit and reacts to generate hydrogen under the action of electrodes. At this time, the temperature is controlled at 5°C; When a large amount of hydrogen is enriched and passes through the nanoporous fiber membrane on the side of the microreactor (pore size 100 nm; θ = 30°), the electrodes are turned off, and the ultrasonic generator (50KHz low frequency for 3 min; 400KHz high frequency for 10 min) is controlled to treat the hydrogen liquid. The mixed system causes linear oscillation and cavitation effects, thereby forming interfacial hydrogen nanobubbles (~150 nm) and gradually transforming into bulk hydrogen nanobubbles (~20nm); ultrasonic cavitation and the energy release and microjet effect of part of the bubble rupture are complet...

Abstract

An ultrasonic-electrode-nanoporous membrane coupling hydrogen production sterilization system, including a container, and several hydrogen production units arranged in the container, the hydrogen production unit includes a cavity, and a broadband ultrasonic generator located in the cavity, An annular hydrogen-producing electrode, which surrounds a broadband ultrasonic generator; the bottom film at the bottom of the cavity is an inner hydrophobic outer hydrophilic film; the side film is an inner hydrophilic outer hydrophobic film, installed vertically or Install obliquely at 0°~45°. The system has the functions of continuously and efficiently promoting the self-circulating microflow of the liquid system, dissolving hydrogen (in the form of nano-bubbles) and interfacial-bulk phase bubble transformation, dispersion, and sterilization. The antibacterial functional beverage prepared has a high hydrogen content (3-6ppm) , wherein the diameter of hydrogen-rich nanobubbles can be distributed in the range of 20-1000nm, and the unsealed state can also be kept stably for more than 8-36h. The preparation method of the present invention is simple, intelligent, efficient, and the product is high-quality, green, and healthy, avoids a large amount of waste of hydrogen charging and high-pressure energy consumption, prevents secondary pollution system of processing, and meets food-grade requirements.

Description

technical field [0001] The invention relates to a unit combination system for generating hydrogen-rich nano-bubbles and a method for preparing an antibacterial functional drink, belonging to the technical field of liquid food processing. Background technique [0002] With the increasing development of hydrogen science, people's cognition and demand for hydrogen and human health care, diet are also increasing. Hydrogen is the simplest, smallest molecule, and most widely distributed element in nature. As early as 2007, Japanese scientists discovered the selective antioxidant ability of hydrogen, which has attracted many scholars to study it. Hydrogen has the characteristics of strong penetrating power and fast diffusion speed, and can enter any part of the body to exert anti-oxidation, anti-inflammation, anti-apoptosis and other mechanisms. Compared with other commonly used food-grade antioxidants (such as vitamin C, polyphenols, etc.), hydrogen itself has a simple structure ...
