Embodiment 1

[0016] The weight ratio of the components is 60% of calcium oxide, 16% of soda ash, 16% of potassium carbonate, and 8% of aluminum powder. Then it is prepared into a powdery heating agent and packaged in a non-woven bag, and it is packaged in an air-tight plastic bag for external use, and the water is packaged in a water-tight packaging bag alone; when it needs to be used for heating food and disinfection, first open the outer packaging plastic bag , After mixing the non-woven fabric bag containing the heating agent and water, the temperature rises immediately, and a heat of 130°C can be generated within 1 minute, which can achieve the purpose of sufficient heating and disinfection.

Embodiment 2

[0018] The weight ratio of the components is 60% calcium oxide, 16% soda ash, 16% potassium carbonate, and 8% aluminum powder. After mixing, an oxidative heating reaction occurs, and then it is prepared into a powdery heating agent and packaged in a non-woven bag for external use. Seal in an airtight plastic bag, and pack 100ml of water in an impermeable bag; when cooking and heating food, first tear off the outer plastic bag, and then put the non-woven bag containing the heating agent in the cooking and heating At the bottom of the lunch box, open the water package, pour water into the box, and quickly put the container containing instant food or meals into the lunch box, the heating pack will immediately heat up within 5-8 seconds when it meets water, and the temperature can reach 70°C. The steam temperature exceeds 130°C within 1 minute, and the maximum temperature can rise to 170°C, and the food can be heated or steamed within 5 minutes.

Abstract

The invention relates to a spontaneous heating agent which comprises the following components in percentage by weight: 60% of calcium oxide, 16% of sodium carbonate, 16% of potassium carbonate and 8% of aluminum powder. The spontaneous heating agent is fast to heat, high in temperature, low in cost, and small in size, the weight of a heating packet is only 40-50g, thus being convenient to carry when people goes out; the spontaneous heating agent does not release extraneous odor and is free of environmental pollution in an exothermic reaction, and has a wide application range, can be used in various heating and disinfection fields, can facilitate the heating of food and beverages as well as the steam sterilization of a medical instrument bag, and the like.

Description

technical field [0001] The invention belongs to the technical field of rapid heating of self-heating food, in particular to a self-heating agent. [0002] Background technique [0003] With the increasing pace of modern life, people have higher and higher requirements for the efficiency of doing things, and eating is no exception, so convenience food has emerged as the times require. We all know that most foods taste better when heated, but these convenience foods generally do not have automatic heating devices; Food, therefore long-term consumption of these convenience foods that do not have an automatic heating device will directly affect people's health. Especially for some special groups such as frontier posts, army camping and training, field exploration and investigation, civilian police performing tasks, long-distance flood fighting and rescue, traveling, and other outdoor personnel, in the absence of power supply, fire source, open flame, cooking utensils, etc. It...
