Abstract: A pneumatic suction device (1) comprises a main nozzle (10), through which the expansion of compressed gas is designed to generate, by means of a reaction, suction with a given vacuum and flow rate. At least one secondary nozzle (20), through which the expansion of the compressed gas is designed to generate, by means of a reaction, suction with a lower flow rate and a higher vacuum that those obtained with the main nozzle (10). Each secondary nozzle (20) is mounted to move between a passive position, in which the effective expansion of the compressed gas is performed by the main nozzle (10) and an active position, in which the effective expansion of the compressed gas is performed by the secondary nozzle (20).

Abstract: The invention concerns a device for heating and/or cooking food comprising: a steam generator producing steam for heating or cooking food; a cooking container receiving a removable cooking basket provided with through apertures arranged in the proximity of the base to allow the steam through. The container being reversibly sealed at its upper end with a removable lid. The removable lid is provided with a through aperture to allow the steam generator to communicate with the container inside, and particularly the cooking basket inside. The container is provided with a through aperture arranged substantially near the top end of the wall defining it.
