A mold (8) provided with a steam vent portion in an insulating portion thereof is used. The mold (8) is heated under a reduced pressure while ejecting steam generated by the heating through the steam vent portion. Dielectric breakdown is prevented which is ascribed to the condensation of a large quantity of steam generated from the material during the thermal molding of cakes by electric heating or induction heating.

Why it's free to use
- Filed November 14, 1997 and granted January 22, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 14, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 14, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
