Specifically, an embodiment of the present inventive concept provides a venturi nozzle apparatus which mixes water and a gas to dissolve the gas in the water, the venturi nozzle apparatus including a housing in which a flow pipe through which at least one of the water and the water in which the gas is dissolved selectively flows and a bypass pipe which communicates with the flow pipe to selectively bypass at least one of the water and the water in which the gas is dissolved flowing through the flow pipe are disposed, an injector unit which is detachably inserted into the flow pipe of the housing and configured to selectively receive the gas and the water to dissolve the gas in the water, and a valve member which is inserted into the bypass pipe of the housing and configured to cause at least one of the water and the water in which the gas is dissolved to flow to at least one of the flow pipe of the housing and the bypass pipe of the housing.

An aerator for aerating a liquid as the liquid is being poured from a container includes an aerator body configured to be at least partially inserted into the container. The body includes an inlet, an outlet, and a flow control chamber disposed between the inlet and the outlet. A flow control element is movably disposed in the flow control chamber between a first position where the flow control element is spaced away from a stop and a second position where the flow control element engages the stop. The flow control chamber communicates with the outlet when the flow control element is in the second position allowing liquid to be poured from the container and allowing air to be introduced into the flow control chamber for mixing with the liquid being poured from the container to aerate the liquid being poured from the container.

The device is a gas-liquid mixing device having a venturi structure in which a throat portion and an enlarged diameter portion are provided in a main passage through which a liquid passes, the gas-liquid mixing device including a collision chamber provided on an outer periphery of the enlarged diameter portion, and a stirring chamber provided downstream of the enlarged diameter portion. A collision flow path communicating with the collision chamber and causing a gas-liquid to collide with an outer peripheral wall, a straight flow path through which the gas-liquid passing through a central portion of the enlarged diameter portion travels straight, and an outer ring flow path through which the gas-liquid flows from the collision chamber to the stirring chamber are formed downstream of the enlarged diameter portion. The gas-liquids from the outer ring flow path and the straight flow path are stirred in the stirring chamber.

A system for meat processing may include: a conveyor configured to transport animal carcasses or portions of meat through a meat processing facility; and a spray system configured to spray each of the animal carcasses or portions of meat with aqueous ozone when each of the animal carcasses or portions of meat is transported to the spray system by the conveyor. The system may further include a second spray system configured to spray each of the animal carcasses or portions of meat with lactic acid or citric acid when each of the animal carcasses or portions of meat is transported to the second spray system by the conveyor.

A nanobubble nozzle includes a body; an inlet for receiving a liquid; an outlet for discharging the liquid with nanobubbles; a forward channel extending through the body from the inlet to the outlet for transmitting the liquid, the forward channel having a venturi throat; a return channel extending from the outlet to recirculate a portion of the liquid and mix it with a gas to form a two-phase mixture; and an inlet port connecting the return channel to the venturi throat. The liquid flow through the throat creates a suction drawing the two-phase mixture into the throat. A cross-sectional area of the forward channel decreases from the inlet to the throat and increases from the throat to the outlet so that an internal pressure lower than an external pressure outside the body and lower than a vapor pressure of the liquid flowing through the throat is provided at the throat.
