<p>PCT No. PCT/EP81/00112 Sec. 371 Date Apr. 4, 1983 Sec. 102(e) Date Apr. 4, 1983 PCT Filed Aug. 4, 1981 PCT Pub. No. WO83/00425 PCT Pub. Date Feb. 17, 1983.The heating device for heating liquid and solid products comprises a heating element intended to heat a food preserve (314) or container structure. The heating element consists of a flat tile like element including a heat spreading layer (308) made of heat conducting material, an intermediate layer (303) composed by an exothermic gas-less combustible material and a layer of heat insulating incombustible material (301). The intermediate layer contains internal walls (302) defining a fire path in order to control the duration of the exothermic reaction. Ignition means comprises a cup-shaped primer (305) with in its center a protruding cone (307) and a starter (311) consisting of a striker arranged to be drawn across a friction sensitive element and intended to ignite the tip of said cone (307) of the primer (306), which in its turn induces the reaction to the combustible material (303). In the later the reaction progresses at a speed comprised between 4 and 20 mm per second and the heat released is dissipated by the heat spreading layer from where it flows into the medium to be heated (314).</p> |
