TRANSPORTABLE APPARATUS FOR HEATING FOOD AND TRANSPORTABLE HEATING DEVICE

The invention relates to a transportable device for heating foodstuffs, comprising a container (1) for receiving the foodstuff (8) as well as a closed-off heating chamber (2) which adjoins said container (1) and is thermally coupled thereto while simultaneously being hermetically separated therefrom by means of a shared, thermally-conductive wall (4). The heating chamber (2) comprises a first chamber (5) and a second chamber (6) that are separated by a water vapour- permeable wall (7). In the first chamber (5) is a substance or a substance mixture (9) which, when a liquid, preferably water, is supplied, generates heat in an exothermic chemical reaction with water vapour being formed. In the second chamber (6), a zeolite (10) is located which can adsorb the water entering from the first chamber (5) by means of said water vapour-permeable wall (7), generating heat. A transportable heating element which can be used in said device contains a hermetically-sealed heating chamber (2) that adjoins a thermally-dissipating outer wall (4).
