Title:
THAWING DEVICE
Document Type and Number:
Japanese Patent JPS5729277
Kind Code:
A
Abstract:

PURPOSE: To thaw a frozen food, etc. in a short time without dissipating electric power, by using a material to regenerate latent heat, which causes change of phase and releases heat stored until the time when it is cooled to a fixed temperature.

CONSTITUTION: A support for a matter to be thawed consists of the outer peripheral container 21 formed into a hollow plate made of a good thermal conductive material and the material 22 to regenerate latent heat which is sealed in the outer peripheral container 21, causes change of phase and releases heat when it is cooled to a fixed temperature, for example, comprising a paraffin, inclusion hydration, etc. For example, when the matter P to be thawed at -15°C is placed on the support 2, the temperature of the support 2 is dropped quickly and reached to 18°C, the matter 22 to regenerate latent heat causes change of phase and releases heat which is stored in the form of latent heat in the material 22 to regenerate latent heat, and the matter is thawed quickly at 18°C.
