An ultra-fine bubble-containing liquid generating apparatus (UFB-containing liquid generating apparatus) includes a dissolving unit that generates a gas dissolving liquid and an ultra-fine bubble generating unit that generates ultra-fine bubbles in the gas dissolving liquid. Additionally, the UFB-containing liquid generating apparatus includes a temperature controlling unit that controls at least one of temperatures of the dissolving unit and the ultra-fine bubble generating unit such that the temperature of the ultra-fine bubble generating unit is equal to or lower than the temperature of the dissolving unit.

A manufacturing apparatus for a solidified matter of an ultra-fine bubble (UFB)-containing liquid includes: a UFB generating unit that generates the UFB-containing liquid; and a cooling unit that generates the solidified matter of the UFB-containing liquid by cooling the UFB-containing liquid. The cooling unit cools the ultra-fine bubble-containing liquid such that a first solidified portion and a second solidified portion at a lower ultra-fine bubble concentration than that of the first solidified portion are formed in the solidified matter.

Provided is an ultra-fine bubble-containing liquid manufacturing apparatus that can suppress viable cell contamination inside a UFB generating unit. To this end, it is provided with an ultra-fine bubble generating unit that generates an ultra-fine bubble by making film boiling by a heating unit in a liquid in which a gas is dissolved, and a radiating unit that is capable of irradiating a wetted portion of the ultra-fine bubble generating unit with ultraviolet rays.

A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.

The present invention provides an ultrafine bubble-containing liquid producing apparatus capable of reducing the possibility of intermitting supply of a UFB-containing liquid. An ultrafine bubble-containing liquid producing apparatus includes producing units that produce an ultrafine bubble-containing liquid containing ultrafine bubbles by using a liquid supplied from a liquid introducing unit and deliver the produced ultrafine bubble-containing liquid to a liquid delivering unit. The producing units include a plurality of ultrafine bubble generating units capable of operating independently. Each of the plurality of ultrafine bubble generating units is provided to be capable of independently switching between communicating with and being disconnected from the liquid introducing unit and the liquid delivering unit.

Provided is a method of producing a solid dispersion that can improve solubility of a hardly soluble polyphenol in water. Specifically, provided is a method of producing a solid dispersion containing an amorphous hardly soluble polyphenol, the method including the steps of: mixing (A) a hardly soluble polyphenol, (B) at least one selected from the group consisting of a plant-derived polysaccharide, a seaweed-derived polysaccharide, and a microorganism-derived polysaccharide, a plant-derived polypeptide, and a microorganism-derived polypeptide, and (C) at least one selected from the group consisting of a monosaccharide and a disaccharide, followed by melting of the mixture by heating; and solidifying the molten product by cooling.

Provided is a technique which enables highly efficient, low-cost production of a sufficiently disinfected high-quality rice gel using a rice gel production system and a rice gel production method for producing a rice gel. The present invention is provided with: a heating/stirring unit for heating a rice material with water added thereto in a sealed container under stirring, thereby providing a gelatinized product; and a pulverizing unit for pulverizing the gelatinized product obtained in the heating/stirring unit thereby providing a rice gel.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 μm. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

An ultrafine bubble generating apparatus and an ultrafine bubble generating method capable of efficiently generating an ultrafine bubble-containing liquid with high purity are provided. In order to this, a heating element provided in a liquid is caused to generate heat, and film boiling is made on an interface between the liquid and the heating element. A film boiling bubble is generated by the film boiling, and ultrafine bubbles are thus generated near the film boiling bubble.
