The present invention relates to an unit for the production of volume-increased, scoop-dispensed ice cream preparation at a ready temperature of under -4 °C, which has mixing vessel (10) with a delimiting wall (11) surrounding the work space (12) suitable for accommodating the ice cream preparation and a mixing body (30) fitted with blades (31) and located in the mixing vessel (10) so that it may rotate, the mixing vessels (10) wall (11) is supplied with at least one transfer opening (13) serving to place the ingredients used for the production of the ice cream preparation into the work space (12) of the mixing vessel (10) and to remove the ready ice cream preparation from the work space (12), and the transfer opening (13) is sealed with a removable cover (20), and the wall (11) of the mixing vessel (10) and/or the cover (20) is supplemented with a gas- feed pipe end (15) that has a dispensing channel (15a) suitable for placing the gas phase ingredients also required for the production of the volume-increased ice cream preparation into the work space (12) of the mixing vessel (10). The characteristic feature of the invention is that the mixing vessel (10) is constructed as a pressure vessel suitable for withstanding at least 1.2 bar, the cover (20) is fixed to the mixing vessel (10) sealing the transfer opening (13) with a gas-tight seal suitable for retaining the pressure in the work space (12), and the gas-feed pipe end (15) is connected to the mixing vessel (10) in a way suitable for receiving a gas phase medium at least 1.2 bar and for transferring it into the mixing vessel (10). The present invention also relates to a procedure for the production of volume- increased, scoop-dispensed ice cream by the introduced unit in such a way that, after placing the prepared ice cream base into the work space (12), the work space (12) is hermetically sealed with a gas-tight seal (40), then a gas phase medium at a pressure of at least 1.2 bar is fed into the work space (12)
