Abstract: Apparatus for generating, at a target ice/liquid ratio with a corresponding target temperature, a slush comprising frozen and non-frozen liquid comprises a flow path for recirculation of liquid therethrough, the flow path comprising a heat exchanger having a coolant inlet and a coolant outlet, the heat exchanger being configured for flow therethrough of coolant at a temperature below the target temperature, the apparatus being configured to vary the rate of coolant flow through the heat exchanger between a first rate and a second rate that is lower than the first rate.

Abstract: Disclosed herein is a heat transfer device (2), the heat transfer device comprising a heat exchanger (10) driven by movement of a fluid, a heat transfer cavity (6) and a fan (12) for creating a circulating gas flow between the heat exchanger and the heat transfer cavity. The heat transfer device (2) includes: a housing having an opening (14) for allowing an object to be inserted into the heat transfer cavity (6); an outlet valve (52) for exhausting gas and/or liquid from the heat transfer cavity (6); and a controller arranged to operate the outlet valve (52). The heat transfer device (2) may, for example, take the form of a cooling device for rapidly cooling a drinking vessel such as a beer glass.

Abstract: An aerosol generation mechanism where a liquid mass is arranged to impinge a liquid-phobic surface (3). The liquid spreads across the liquid-phobic surface (3) without wetting it and at some point breaks up into an aerosol cloud (4).
