Self-heating disaster-proof emergency food package and heating method thereof

Abstract

The invention discloses a self-heating disaster-proof emergency food package and a heating method thereof. The self-heating disaster-proof emergency food package comprises a heat-insulating shell and a self-heating bag, wherein the heat-insulating shell is made of aluminum complex foil pearl wool; the self-heating bag is prepared by arranging a self-heating element in a sealing bag; a mixture of calcium oxide and aluminum powder or magnesium powder serves as the self-heating element; the self-heating bag is wrapped in the heat-insulating shell; a water bag is also arranged in the heat-insulating shell; food with a sealing package is arranged in the heat-insulating shell. During a use process, two heating bags are taken out and are respectively placed on the two sides of the food with the sealing package and are put into the heat-insulating shell, the water bag with metering scales is opened, and then water, the mass of which is 2-3 times of the mass of the self-heating element, is poured onto the self-heating bag, the self-heating bag absorbs water, and then the longer side of the opening port of the heat-insulating shell is bent toward the shorter side so that the opening port of the heat-insulating shell is sealed, and then the sealing is kept for more than 15 minutes till reaching the proper temperature, so that the heating is finished.
