The present invention discloses an ultrasound-electrode-nano-porous membrane coupling hydrogen production and sterilization system, which comprises a vessel and a plurality of hydrogen production units arranged in the vessel. The hydrogen production unit comprises a cavity, and a broadband ultrasonic generator and a circular hydrogen production electrode located in the cavity. The circular hydrogen production electrode wraps around the broadband ultrasonic generator. A bottom membrane at the bottom of the cavity is hydrophobic at the inner side and hydrophilic at the outer side, and a side membrane of the cavity is hydrophilic at the inner side and hydrophobic at the outer side and is mounted vertically or obliquely upwards by an angle of 0-45 degrees. The system has the functions of continuously and efficiently facilitating self-circulation micro-flow of a liquid system, hydrogen dissolution (as nano-bubbles), conversion from the interface to the bulk phase and dispersion of bubbles, sterilization and others. The hydrogen content in a prepared anti-bacterial functional beverage is high (3-6 ppm), wherein the diameter of hydrogen-rich nano-bubbles is distributed within the range of 20-1000 nm, and the nano-bubbles are retained for 8-36 hrs or more even in an unsealed state. The means of preparation of the present invention is simple, intelligent and efficient, the product is high in quality and green and has a health care function, waste of a lot of filled hydrogen and high-pressure energy consumption are avoided, secondary pollution of the system is prevented in processing, and food-grade requirements are met.

A method including sonication of a yogurt culture produces desirable texture and yield characteristics. An apparatus for producing yogurt from milk includes a sonicator for controlling texture.

A device and a method are for sterilization of milk from livestock such as cows, sheep or goats. The milk, prior to an irradiation with UV-C light through a light translucent barrier, is homogenized since the milk is exposed to ultrasound. The milk simultaneously to or after the homogenization is exposed to an electrical field, such as a field with changing polarity, where polarity change and field strength are chosen such that the milk in the electrical field is heated due to the milk's resistance.

Disinfecting particulate material includes combining the particulate material with a photocatalyst to yield a mixture, irradiating the mixture for a length of time with pulses from a light source having broadband emission spectrum between 190 nm-1100 nm to yield an irradiated mixture, and separating the photocatalyst from the disinfected mixture to yield the disinfected particulate matter. Irradiating the mixture inactivates microorganisms in the mixture to yield a disinfected mixture. A system for disinfecting particulate material includes a pulsed light source having a broadband emission spectrum in a range between about 190 nm and about 1100 nm, a chamber defining a cavity optically coupled to the pulsed light source, a humidifier, a fan, and one or more sensors. The chamber includes a conveyor configured to accept the particulate material and arranged such that the pulses emitted by the pulsed light source irradiate the particulate material on the conveyor.

A cylindrical piezoelectric transducer is described the cylindrical piezoelectric transducer comprising: a tube having inner and outer surfaces and a first inner diameter, first outer diameter and a first thickness; at least one stepped band having a stepped inner diameter, stepped outer diameter and stepped thickness and wherein the stepped thickness is less than the first thickness and the at least one stepped bands are spaced along the length of the tube and alternate with bands of the first thickness; and conductive material disposed over the inner and outer surfaces of the tube.

A device for inactivating or reducing an amount of biological contaminants in human milk comprises an interior for taking in human milk to be treated in order to inactivate or reduce the amount of biological contaminants, and at least one UV lamp for irradiating the milk being in the interior in order to subject it to the treatment. The treatment is a first function of the device, wherein the device has a second function, the device being capable of fulfilling the first function at the same time as the second function, wherein the second function is one or more of milk expressing, milk collecting, milk storing, milk warming, milk feeding, milk processing and milk handling.
