Abstract: A food processing apparatus includes a reaction vessel that has a tubular shape with a bottom and contains a reactant that is liquid and to be used for food, a reactor (for example, a reaction pipe) that is disposed in the reaction vessel and provided with a photocatalyst, a light source that irradiates the photocatalyst with light, a cooler that cools the reactant in the reaction vessel, a lid that closes an opening of the reaction vessel, and a gas supplier (for example, a gas container) that supplies an oxygen-containing gas into the reaction vessel via a first through-hole formed in the lid or in a part of a side wall portion of the reaction vessel in a vicinity of the lid. An inside of the reaction vessel is controllably gastight.

Abstract: A food processing apparatus includes a reaction tank having an internal space for storing a reactant that is in a liquid state and that is used for food, a cooler that cools a reactant stored in the reaction tank, and a catalytic reactor disposed in the internal space. The catalytic reactor includes a reaction tube, a light source disposed in the interior of the reaction tube, and a heat insulator disposed between the reaction tube and the light source. The outer surface of the reaction tube is provided with a photocatalyst. The reaction tube allows light radiated from the light source to pass therethrough. The reaction tube has a first end, and the first end is closed so as to serve as a bottom surface of the reaction tube. The thermal conductivity of the heat insulator is lower than the thermal conductivity of the reaction tube.

Abstract: The present disclosure provides a liquid treatment method and apparatus according to which poorly treated liquid is prevented from being discharged to the outside thereof. The liquid treatment apparatus of the present disclosure comprises a channel switch, a return channel that establishes communication between the channel switch and an internal space of a first tank, and a discharge channel that establishes communication between the channel switch and the outside of the liquid treatment apparatus. In the circulation state, the liquid mixture is circulated in the liquid treatment apparatus so as to return a liquid to the first tank through the return channel. If a concentration of the photocatalyst particles contained in the first tank falls within a predetermined range, the channel switch is switched from the circulation state to the discharge state to discharge the liquid to the outside of the liquid treatment apparatus.

Abstract: The present invention provides a photocatalyst particle comprising titanium dioxide particles, a zeolite particle, and a carbon layer. The titanium dioxide particles are adsorbed on a part of an external surface of the zeolite particle. The carbon layer coats a part of an external surface of the zeolite particle other than the part of the external surface of the zeolite particle on which the titanium dioxide particles are adsorbed. The carbon layer is in contact with a part of surfaces of the titanium dioxide particles. At least a part of the other part of the surfaces of the titanium dioxide particles is not coated with the carbon layer and are exposed on a surface of the photocatalyst particle. The present invention provides a photocatalyst particle used even in an alkaline aqueous solution.

Abstract: A method for operating a food processing device includes an irradiation step. The food processing device includes a reaction vessel and a catalyst reactor. The reaction vessel receives a mixture in a liquid form including a raw material for a food product and water. The catalyst reactor is disposed in the reaction vessel. The catalyst reactor includes a reaction tube and a light source disposed in the reaction tube.

Abstract: A water treatment method includes: introducing an aqueous solution containing impurities into a first tank; irradiating, from a light source, photocatalytic particles with ultraviolet light, to turn the aqueous solution introduced into the first tank into primary post-treatment water with which the impurities have been treated; reducing pressure in a first chamber by a filtering pump to filter the primary post-treatment water with a filtering membrane, the filtering separating the primary post-treatment water into the photocatalytic particles stopped at the filtering membrane and secondary post-treatment water that passes through the filtering membrane and does not contain the photocatalytic particles; measuring concentration of photocatalytic particles in the first tank; measuring the difference in pressure between the first chamber and the second chamber; and when the concentration of the photocatalytic particles is equal to or smaller than the first threshold value and the difference in pressure between the first chamber and the second chamber is greater than the second threshold value, supplying air to the filtering membrane by operating a compressor.

Abstract: A food processing device includes a reaction vessel, a stirrer including a stirring body, and catalyst reactors. Each catalyst reactor includes a reaction tube and a light source. The reaction tube has an outer surface on which a photocatalyst is provided, and transmits light. The catalyst reactors are arranged around a rotating shaft. The light source includes light emitters disposed at different positions. When viewed in an axial direction of the rotating shaft, the catalyst reactors have equal phases. The phase of each catalyst reactor is a phase of a reference direction of the reaction tube of the catalyst reactor with respect to a straight line connecting centers of the rotating shaft and the reaction tube. The reference direction of the reaction tube is a direction determined on the basis of a direction in which light is emitted from the light emitters and a positional relationship between the light emitters.

Abstract: A method for operating a food processing apparatus is provided. The food processing apparatus includes a reaction vessel that has a space that accumulates a liquid reactant used for a food product; a catalytic reactor that includes a reaction tube and a light source; and an introducing tube for introducing the reactant into the reaction vessel. The reaction tube has an outer surface where a photocatalyst is provided. The reaction tube transmits light. The light source generates heat at a time of light emission in which the light source emits light from an inner side of the reaction tube. The method for operating the food processing apparatus includes introducing the reactant into the reaction vessel from the introducing tube. In the introducing, the reactant is introduced up to a position at which a liquid surface of the reactant is positioned higher than an opening portion of the introducing tube.
