A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A tube has a first end and an opposing second end, the first end of the tube being disposed within the compartment of the container. A nozzle is disposed within the compartment of the container and has at least one outlet, the nozzle being coupled with the tube so that a gas can be passed through the tube and out the at least one outlet of the nozzle. The nozzle is sufficiently buoyant so that when a fluid is disposed within the compartment of the container, the nozzle floats on the fluid.

An ingredient blending apparatus is disclosed which blends a plurality of ingredients into a homogeneous blend. The apparatus includes a container which receives various ingredients in a prescribed amount. A vacuum motor has its intake side in communication with the interior of the container to suck the ingredients from the container and blow the same into a blending chamber. The ingredients blown into the blending chamber are mixed and recycled into the vacuum motor and the blending chamber until the ingredients are properly mixed or blended. When the ingredients are properly mixed or blended, they may be sent to an ingredient collection apparatus.

Disclosed is a device for contactlessly mixing fluid present on the upper surface of the slide, where the device comprises a first nozzle array and a second nozzle array, the first nozzle array adapted to impart a bulk fluid flow to the fluid present on the upper surface of the slide, and the second nozzle array adapted to impart at least a first regional fluid flow to at least a portion of the fluid present on the upper surface of the slide.

A system for performing a gas-liquid mass transfer includes a container bounding a compartment and having a top wall, a bottom wall, and an encircling sidewall extending therebetween. A first opening is formed on the container so as to communicate with the compartment. A liquid is disposed within the compartment and having a top surface disposed below the first opening. A gas is blown through the first opening so that the gas passes over at least a portion of the top surface of the liquid, the gas producing turbulence on the top surface of the liquid that is sufficient to produce a mass transfer between the gas and the liquid. A mixing element is disposed within the compartment.
