Abstract: An apparatus for heating foodstuffs contained in packages of parallelopiped shape which includes a container for a heating medium, a placing table disposed inside the container, and a heater for heating the heating medium. The placing table has rectangular cylindrical elements between which the foodstuffs are placed. The faces of the rectangular cylindrical elements which face the foodstuffs on either side are roughly the same size as the faces of the foodstuffs which face the rectangular cylindrical elements and have discharge holes to facilitate the flow of the heating medium. The heated heating medium is circulated from below the placing table, up through the placing table, out through the discharge holes of the cylindrical elements and into contact with the packages, thus providing for quick and efficient heating of the foodstuffs.
