In a method and apparatus for continoulsy producing a heated roll-shaped food, a horizontal type of cylindrical or bell-shaped heating drum is rotated and heated while coated with a scorch-retarding oil film on the inner peripheral surface thereof and raw material is poured onto the inner peripheral surface thereof. The raw material is heated while spreading out on the inner peripheral surface of the heating drum with aid of fluidity of the raw material and the rotation of the drum. The heated raw material swells up along the inner peripheral surface of the heating drum, and is exfoliated from the inner peripheral surface due to its weight and reversed at a head edge portion thereof. Thereafter, the exfoliated and reversed tip edge portion of the gelled raw material is overlaid over a portion of the raw material which continuously swelling up to thereby form a core of the overlaid portions of the raw material and the continuously swelling raw material is rolled up around the overlaid portions serving as the core by means of its weight and an angular moment which is applied to the overlaid portions of the raw material due to the rotation of the heating drum. Finally, a roll-shaped product is taken out from a tip portion side of the heating drum. All of the above steps are continuously carried out.
