Efficient foodstuff heat-emitting package

Abstract

The invention provides an efficient foodstuff heat-emitting package. A heat-emitting composite of the package is mainly obtained by mixing several ingredients out of aluminium powder, calcium oxide, calcium hydrate, kieselguhr, silica dioxide, sodium chloride and calcium carbonate with sodium fluoride in a certain proportion, the materials are cheap and wide in source, and the cost is low. The sodium fluoride content is 3%-10%, the aluminium powder content is 15%-35%, the heat-emitting temperature is as high as 97 DEG C, the package has the advantages of being high in heat-emitting temperature, long in duration time, wide in material source and the like, the moisture absorbing effect before the reaction is not obvious, the spontaneous exothermic phenomenon does not exist fundamentally, no objectional odor is generated in the reaction process, and the appetite of a person is not affected; the product after water is added and the reaction is conducted is hardened into a block, and no pollution is caused to the environment. The package can be well applied to the field of fast foodstuff.

Description

technical field [0001] The present invention relates to, in particular to a heating composition, in particular to a high-efficiency food heating pack. Background technique [0002] With the accelerated pace of people's life, many people are busy with work and have no time to cook, or they don't want to cook dishes at home alone during holidays. At this time, instant food with high-efficiency heating packs can bring us convenience and speed; and now Many people like outdoor camping and hiking, and some even stay overnight in deep mountains and old forests. In virgin forests, there is no power supply and open flames are strictly prohibited. At this time, it is a very happy thing to be able to eat a steaming meal outdoors far away from home , These heating instant foods do not need power supply, no open flame, they can automatically heat up just by adding water, and can deliver steaming and delicious food to people. People use it under conditions of travel and camping; this ...

Problems solved by technology

For example, CN200710121281.6 discloses a preparation method of "a kind of flameless heating agent", which is mainly prepared by mixing aluminum powder, sodium sulfate, calcium oxide and sodium hydroxide according to a certain ratio, but sodium hydroxide is easy to absorb moisture. The heat pack produced is easy to self-heat during the production process, which not only wastes energy, but also is inconvenient to make

CN201310145025.6 disclosed "a kind of Al-KMnO 4 -MnO2 self-heating material preparation method", the preparation method is mainly made by mixing aluminum powder, potassium permanganate, manganese dioxide and fillers such as diatomaceous earth and tartaric acid in a certain proportion, but this product is used The proportion of aluminum powder and potassium permanganate is too high, which makes the production cost very high. Although the calorific value is high, the packaging bag is easy to break, and the overflowing potassium permanganate will be flammable and explosive when it encounters flammable materials. Unsafe factors, and the reaction products will pollute the environment

At present, most heating agents on the market have some peculiar smell, and are easy to pollute the environment, and even some heating packs do not provide enough heat to heat food
