CONTACT HEATER OF PACKED FOOD PRODUCTS Russian patent published in 2009 - IPC A47J36/28 F24J1/00 B65D83/74 

FIELD: food industry.

SUBSTANCE: invention relates to food industry, particularly to the devices of heating food products before their consumption with the help of exothermal chemical reaction. The contact heater of packed food products contains a container with two different heat transmitting walls located one against each other, and a closed cavity for water-initiating exothermal composition. The container is made from flexible porous nonwoven material and contains a cover made from gas and water proof material. The container is equipped with a cover made from gas and water proof fibre glass cloth and is located in the cavity of the cover. The container closed cavity is filled with water initiated exothermal composition of uniform mix of calcium oxide and waterless silica gel with the content of last in the amount of 1 part to 3.5-6.0 weight parts of calcium oxide. The casing is made with two heat transmitting surfaces and inlet opening, that closes after the cover cavity is filled with water.

EFFECT: provision of an increased productivity of heat usage evolved in the result of exothermal chemical reaction, increase of security and provision of duration of evolving heating energy up to 8-10 minutes.
