A gas injection system for injecting a gas into a liquid to form a solution includes a flow channel that conveys a liquid from an upstream inlet configured to receive the liquid and a downstream outlet configured to dispense the solution, sparger positioned in the flow channel, a solution pressure detection device configured to sense a pressure of the solution in the flow channel, and a liquid valve configured to regulate flow of the liquid in the flow channel based on the pressure sensed by the solution pressure detection device. The sparger is configured to inject the gas into the liquid through the porous surface as the liquid flows across the surface.

A degassing system includes a degassing tank with a first space area configured for having liquid introduced therein and a second space area configured for having the liquid from the first space area introduced therein. The first and the second space area are partially separated from one another by a separation element. The degassing system includes a controllable pump configured to pump liquid from the first space area to the second space area for a two-stage vacuum degassing process responsive to the pump being operated. The degassing system includes a control device configured to control the pump to not be operated for a single-stage vacuum degassing process and to be operated for a two-stage vacuum degassing process.

A water container with an ozone diffuser is an apparatus that is used to diffuse ozone gas into water that is either flowing through the apparatus or is retained by the apparatus. The apparatus includes an aeration chamber, an ozone generator coupler, a distribution hub, a plurality of porous tubes, and a degassing unit. The ozone generator coupler allows the apparatus to connect with a pressurized supply of ozone gas. The aeration chamber is used to retain the water that is currently being aerated by the ozone gas. The distribution hub receives the ozone gas from the ozone generator coupler and distributes the ozone gas amongst the porous tubes. The ozone gas is then evenly inserted from the porous tubes into the water retained by the aeration chamber. The degassing unit is used to neutralize the excess ozone before exhausting the excess ozone into the apparatus's surroundings.

The invention provides a carbonation tank assembly for admixing a gas and a potable liquid used in preparation of drinks. The assembly includes a tank body with an interior that can be easily accessed for cleaning and repair purposes by removing upper and lower end plates securely and sealing fitted by gaskets to the upper and lower ends of the tank. The interior is connected to a liquid source for supplying liquid, a gas source for carbonating the liquid, and drawing means for dispensing carbonated liquid from the interior of the tank.

A nano-bubble water generating apparatus containing an application gas includes a motor, a pump integrated with the motor for supplying liquid, typically water, from an inlet pipe under a predetermined pressure through a supplying pipe to a pressure tank, a nano-bubble water generating tube mounted at the water entrance of a pressure tank, an electronic control portion, a pressure adjuster including an outer air inflowing portion to introduce an outer air or a specific gas supplied thereinto to control a pressure in the pressure tank, uniformly and a pressure adjusting portion airtightly coupled on the upper portion of the outer air inflowing portion to adjust an amount of outer air or specific gas to be supplied, and a nano-bubble water expanding tube for expanding and shattering nano-bubble water through an outlet pipe from the pressure tank, so that the size of the nano-bubble water is better micronized.

An aerator and an associated method and system are provided. The aerator includes an elongate body having a central bore that extends between proximal and distal ends of the body, and a plurality of channels formed in an outer surface of the body, the plurality of channels extending between the proximal and distal ends, and including at least two bends along their lengths. The bends in the channels help to provide a smoother flow of liquids passing through the aerator.

The invention includes components and methodology for fixed and semi-fixed systems for extinguishing fire in large industrial flammable liquid storage tanks, including aerated foam projecting nozzles discharging substantially focused streams together with aeration chambers and risers.

Disclosed herein is a refrigerator capable of producing carbonated water and a control method thereof. The refrigerator includes a carbonated water tank to store carbonated water a carbon dioxide gas supply valve to open/close a carbon dioxide gas flow path to guide carbon dioxide gas from a carbon dioxide gas cylinder to the carbonated water tank, and a carbonated water tank pressure sensor to detect an internal pressure of the carbonated water tank.

Disclosed is a bottom-up liquid filling system, comprising an upper body and a lower body. The upper body comprises a fixed member and a lifting member with a filling passage channel in the middle, wherein the fixed member is fixedly arranged on an inner bottom face of the upper body, the lifting member is arranged inside the fixed member and is movable up and down, a passage hole is arranged in a side wall of the lifting member, and the filling passage channel passes through the bottom of the upper body. The lower body comprises a capping plug, a rigid cylinder, an outer retractable tube and an inner retractable tube, wherein the outer retractable tube is internally provided with a spring, the rigid cylinder is arranged on a top plate and is provided with a channel, the inner retractable tube is arranged inside the outer retractable tube and is in communication with the rigid cylinder, a support cylinder is arranged on a bottom plate, the support cylinder passes through the inner retractable tube and extends into the rigid cylinder, the capping plug connected to the top of the rigid cylinder is fixedly arranged at the top of the support cylinder, and an outer side wall of the capping plug is snap-fitted with an inner side wall of the top of the lifting member. The present invention has the advantages of being less prone to leakage and spilling, having low costs and reducing the chance of scalding.

The present invention is directed generally to the field carbonated beverage dispensing systems having a replaceable carbon dioxide storage cylinder. Such systems may be embodied in the form of a unitary apparatus including, but not exclusively, on-bench, under-bench or freestanding beverage cooling units. The invention may be embodied in the form of a beverage dispensing unit having a gas input connector configured to make gas tight connection to a gas container configured to hold a gas under pressure and a mass detection device. The gas input connector and mass detection device are arranged such that when a gas container is connected to the gas input connector, the mass detection device is capable of detecting a mass associated with the gas container. The unit may further have a gas container support extending from or about the mass detection device configured to maintain a gas container connected to the gas input connector in a position such that it bears on the mass detection device so as to allow the mass detection device to measure the mass of the gas container and any gas contained therein. Computer-implemented methods for monitoring the level of gas are also provided.
