Description

Liquid Phase Beverage Supercooling Device < RTI ID = 0.0 >

The present invention relates to a device for subcooling a liquid beverage.

Supercooling is the process of lowering to a liquid state without becoming solid at below the freezing point.

The liquid passing through the standard freezing point is crystallized in the presence of a seed crystal or nuclei where a crystalline structure can be formed and will produce a solid, and if such seed crystals or nuclei are not present, have.

Water generally freezes at 0 ° C, but can be "supercooled" to about -48.3 ° C from standard pressure to nearly uniform nucleation.

The subcooling process requires that the water be pure and free of nucleation sites, which can be achieved by processes such as reverse osmosis or chemical demineralization, but no special techniques are required for cooling itself.

The state of supercooled liquid is thermodynamically metastable, and when disturbance is applied to the periphery, phase change occurs in solid phase instantaneously.

When a liquid beverage cooled in a supercooled state is poured into a cold cup or shocked or vibrated in a liquid beverage in a supercooled state, the liquid phase changes into a liquid beverage in a completely frozen or unheated state. Slush).
