Abstract: The inventive device comprises a body (1) provided with side walls (3, 4) and superimposed planar horizontally extending induction units (10) between which containers for food to be prepared (20) can be introduced. The induction units (10) are associated by one part (29) of the edge thereof with the respective side wall (3, 4) in such a way that said induction units (10) form the bottom of open compartments (19). Said device also comprises a carriage (30) having a practically vertically extending body (31). Holders (35) for the containers (20) are protruded from the sides of the base body (31) of the carrier. Each container (20) is disposed between two superimposed induction units.

Abstract: The device includes an oven, the inside of which is a space designed to hold food to be cooked and which is designed to generate saturated steam inside this space. The device also includes a dosing appliance for water which presents a duct which passes through one of the walls of the oven. In this duct, there are valves to control the supply of water into the cooking space. The outlet of this device is directed towards a heating element which is also located in the cooking space. The device also includes a steam condenser which is connected to the cooking space.

Abstract: Frozen meals are placed in a hermetically sealable cooking space (2) in which explosion-like puffs of steam are produced. Before the puffs of steam are produced, the air present in the cooking space can be heated. The puffs of steam are produced by evaporation of dosed quantities of water. Water is introduced into the cooking space (2) through a nozzle (40) which opens into the cooking space. The means can be regenerated or even cooked with the greatest possible care in the shortest possible time without detriment to their quality.
