  • Food heating technique for producing high temperature
    Patent number: 5205277
    Abstract: The present invention relates to a high temperature heating technique and container for foods. The container comprises principally quicklime, which is the main component for raising the temperature, a medium temperature heating pack, a high temperature heating pack and a heater lid. The medium temperature heating pack includes a temperature raising liquid for creating a first stage of temperature increase by reacting the quicklime, while the high temperature heating pack includes a temperature raising liquid for creating a second stage of temperature increase. The heater lid contains probes which release the temperature raising liquid in the medium temperature heating packs and the chemical reaction to produce heat which in turn melts the covering of the high temperature heating pack releasing its liquids. These liquids in turn react with the surrounding quicklime to produce a high temperature of up to 250.degree. C. in a very short time.
