PURPOSE:To enable the performance of an electromagnetic cooking tool as well as reinforcing, heat preservation by providing a guard case of heat transfer properties, permeability, etc., made of metal at the outer circumference of the container such as serpentine, etc. CONSTITUTION:The tool of respective types of the shape, size and use is manufactured by using a serpentine and other 23 type rocks and the stone quality and an extreme infrared radiation ability of the serpentine, etc., are used for a diet. Namely, concerning with pickles and fresh food preserving container, the farinfrared rays are requested and then a raw material stone having a rock character like a serpentine is preferable. The system is the one not to engage and insert the stone as a weight in the cylinder but to mount it to the upper part of a container main body and is manufactured by matching it to the outer circumferential size of the container. The processed food preserved in a cylindrical food container keeps freshness by continuously receiving the radiation energy of the farinfrared ray. It can be used as a serpentine farinfrared ray radiation above-and-below floor food preserving container. Since a constant temperature is kept by a stone, a large temperature change does not occur and the freshness of the food in it is held. |
