Abstract: The multifunctional combined apparatus for food preparation is a professional catering or household device for thermal food preparation. This device enables a multipurpose food preparation. The essence of the construction of the new device is introduction of a rotary drum (1) in the interior of the oven. Onto inner surfaces of the rotating drum (1) are attached or shaped out of the drum attachments or shovels (4) which are meant to distribute liquids. In the centre of the drum we can statically place baskets or static sheet metal containers (6). Into the drum (1) we can also place divided chambers (7) for food. Once attached, they rotate together and in the same direction with the drum. The second possibility of the construction is that device is based upon the static drum, where the axis is arranged horizontally and into which are placed rotary attachments meant to attach rotary consoles.
