'Reverse microwave' can chill wine bottles and fizzy drink cans in 45 seconds It uses a stop start rotational sequence to create what is known as a Rankine vortex- which is a collapsed vortex in a viscous fluid. This enables the drinks to mix without fizzing. The beverage is rotated at speed around twin axes in water to keep it in its original state while quickly bringing down its temperature. V-Tex, which invented the technology, say that the process requires more than 80 per cent less energy than many standard drinks chillers.
