Abstract: An apparatus and method for generating ice pellets, in particular for controlling the properties of the generated ice pellets. The apparatus comprises a pellet generation region; at least one nozzle configured to supply a plurality of water droplets to the pellet generation region; a liquefied gas supply configured to deliver a liquefied gas to the pellet generation region to thereby freeze the water droplets to generate a plurality of ice pellets; at least one temperature measuring device configured to obtain data indicative of the temperature of the ice pellets at generation; and a control system configured to adjust the flow rate of water and/or liquefied gas to thereby control the temperature of the ice pellets at generation.
