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

example 1

[0021] Example 1: A high-efficiency food heating pack, consisting of a non-woven bag and a heating composition; the heating composition is prepared by mixing the following materials in a weight ratio: 20 parts of aluminum powder, 45 parts of calcium hydroxide, silicon 5 parts of algae earth, 20 parts of silicon dioxide, 10 parts of sodium fluoride powder.

[0022] The materials are all in powder form. Put the mixed exothermic composition into a non-woven bag and place it in a Dewar bottle, add water twice the mass of the total mixture, and start to steam in 35 seconds, and reach the peak within 4 minutes. 97°C (boiling point temperature), which can last for several minutes, generates a large amount of steam, and the temperature rises to 95°C in 20 minutes, and the temperature can remain at 90°C for 30 minutes.

example 2

[0023] Example 2: A high-efficiency food heating pack, consisting of a non-woven bag and a heating composition; the heating composition is formulated according to the weight ratio of the following materials: 15 parts of aluminum powder, 50 parts of calcium hydroxide, diatom 5 parts of soil, 15 parts of silicon dioxide, 15 parts of sodium fluoride powder.

[0024] Stir the mixed powder evenly and put it into a non-woven bag. Put the packaged heating pack in a Dewar bottle and add water twice the mass of the total mixture. Steam will start to emerge in 25 seconds and reach 95 in 3 minutes. °C, it can last for several minutes, a large amount of steam is generated, and the temperature is not lower than 90 °C in 20 minutes.

example 3

[0025] Example 3: A high-efficiency food heating pack, consisting of a non-woven bag and a heating composition; the heating composition is formulated according to the weight ratio of the following materials: 30 parts of aluminum powder, 50 parts of calcium hydroxide, diatom 4 parts of soil, 13 parts of silicon dioxide, 3 parts of sodium fluoride powder.

[0026] Stir the mixed powder evenly and put it into a non-woven bag. Put the packaged heating pack in the Dewar bottle and add water twice the mass of the total mixture. Steam will start to emerge in 50 seconds, and it will reach the peak in 2 minutes and 30 seconds. At 97°C, it can last for several minutes, and a large amount of steam is generated, and the temperature is not lower than 91°C in 20 minutes.

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 ...
