Rapid high-efficiency heat-generating agent

Abstract

The invention discloses a rapid high-efficiency heat-generating agent comprising calcium oxide, diatomite, activated carbon, salt and active metals. The rapid high-efficiency heat-generating agent generates heat by using the metal instant oxidization principle and comprises the following components in the mixture ratio: 10-15 percent of calcium oxide, 30-40 percent of diatomite, 4-12 percent of activated carbon, 9-15 percent of salt, 20-35 percent of active metals and 60-75 percent of water. The using method of the invention comprises the following steps of: packaging the heat-generating agent by using a non-woven cloth bag, externally packing the heat-generating agent by using an airtight plastic bag and independently packaging water by using a waterproof packaging bag; when food needs heating, tearing off the plastic bag, placing the non-woven cloth bag filled with the heat-generating agent at the bottom of a stewing food box; pouring water into the box, rapidly placing a vessel holding food into the food box; and self heating and sterilizing the food by using high-temperature vapor with more than 130 DEG C self generated in one minute in few minutes. The invention has the characteristics of favorable effect, low consumption, small volume and low cost; in addition, residual products after combustion are blocky diatomite which has no pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of self-heating agent and self-heating food heating thereof, and particularly relates to a rapid and high-efficiency heating agent with fast heating start and long heating duration, which can be used for non-fire heating and environmentally friendly heat source. Background technique [0002] In daily life, the existing convenience food is full of beautiful things in eyes and various in variety, which brings convenience and quickness to many people who are used to fast-paced life and work and travel; but these convenience foods generally do not have automatic heating devices, and most of them The flavor of the food is better when it is heated; moreover, there are many people with poor stomachs who cannot eat food below body temperature in cold weather, so long-term consumption of these convenience foods without automatic heating devices will directly affect people's health. Especially for some special groups...

Problems solved by technology

The disadvantages of self-heating items that have appeared are that most of the unit mass calorific value is small, the amount of heating agent is large (with quicklime as the main ingredient), the heating temperature is not high, the cost of heating technology is high, the shelf life is short, the packaging is too large, and the heating package weighs 80-100g, it is inconvenient to carry and transport, there is a peculiar smell after heating, and the reaction product is mainly calcium hydroxide, which will cause serious pollution to our living environment and is not suitable for promotion and popularization
