PURPOSE:To enable an efficient heating of a heated material contained in a container to be performed within a short period of time by a method wherein a partition wall member within the container is broken to cause an over-cooled molten liquid state and a solid state of non-organic hydrate to be contacted to each other and a condensation heat discharged when the non-organic hydrate of over-cooled molten liquid state is varied in its phase to its solid state is applied. CONSTITUTION:Heated liquid 2 for a heating item and an over-cooled molten liquid 3 of non-organic hydrate are charged in a container 1 through a partition wall 1a within the container 1. A through-pass hole 1b is made at a proper location of the container 1 at a part in direct contact with the over-cooled molten liquid 3 within the container 1 and a solid 5 of non-organic hydrate enclosed within an enclosing member 4 is stored in the through-pass hole 1b while in contact with the over-cooled molten liquid 3 is broken. Therefore, when the enclosing member 4 is broken with a proper breaking means, the solid material 5 within it is comes in contact with the over-cooled molten liquid 3 and then a latent heat caused by a condensation of the over-cooled molten liquid 3 is discharged. With this arrangement, it is possible to heat the heated item within the container easily up to a desired temperature. |
