[0007] Patent CN1580177A discloses "a formula of self-heating food heating agent and its preparation method". Small particles of iron powder are embedded in rolled magnesium and mixed according to a certain ratio. However, the heat energy is released through the redox reaction of iron powder. The heat release is low, and the heat supplied is not enough to heat the food.
Patent CN102634322B discloses the production method of "a preparation method of self-heating food heating agent". The speed is fast, the heating time is short, and the heat sustaining ability is low, and the effect of heating food is greatly reduced
Patent CN105038726A discloses a production method of "a food heating pack", which is mainly composed of aluminum powder, calcium oxide, calcium hydroxide, diatomaceous earth, silicon dioxide, sodium chloride, calcium carbonate and sodium fluoride Mixing according to a certain ratio, the heat release speed of this patent is slow, when it is used as a food heating agent, the heating is slow, the heat loss is serious, and there will be a lot of quicklime odor.

Abstract

The invention provides a novel self-heating food heating bag. The novel self-heating food heating bag consists of a polypropylene nonwoven fabric bag and a heating material, wherein the heating material composition is prepared by mixing aluminum powder of 50 to 200 meshes, aluminum powder of 200 to 400 meshes, calcium oxide, polyethylene glycol, sodium sulfate, coffee carbon powder, ethyl vanillinand lavender essence according to a certain proportion; and the self-heating food heating bag is not limited by time and places, avoids open fire, is safe and reliable, realizes long-time heating, has high heating efficiency, is environmentally-friendly and sanitary, can meet the requirements of customers in many regions and has long shelf life. Furthermore, the novel self-heating food heating bag can produce flavor capable of increasing appetite, is rapid and controllable in heating reaction, is high in cost performance, can be accepted by the customers and can be applied in the field of catering well.

Description

technical field [0001] A novel self-heating food heating pack and preparation method thereof, an Al-CaO-[C 9 H 10 O 3 ·C 10 H 18 The preparation method of O]Na is especially the preparation method of the exothermic composition that the reaction products of two kinds of aluminum-doped compound reaction regenerate heat. Background technique [0002] When traveling with friends, when they are exploring and climbing mountains, and when passengers travel to replenish food. Since most of the foods brought are cold and non-heatable foods, it brings great inconvenience to players and passengers, which greatly reduces the experience of playing, and even affects their own health because there is no hot food. [0003] At present, most instant noodles on the market have high oil content, relatively simple nutrition, certain additives, and lack of variety in taste. It is difficult to meet people's requirements for nutrition and health. People are eagerly looking forward to new alter...
