Example Embodiment

[0014] Example 1. Mix the materials with a weight ratio of 10% to 15% calcium oxide, 30% to 40% diatomaceous earth, 4% to 12% activated carbon, 9% to 15% salt, and 20% to 35% of active metal Afterwards, since the substances of each component are all substances capable of generating exothermic reaction, after instantaneous oxidation and exothermic reaction, they are mixed and then prepared into a 100 mesh powdered exothermic agent, which is packaged in a non-woven bag and packaged in an airtight plastic bag. 60%-75% of the water is individually packaged in impermeable packaging bags; when it is needed to heat food and sterilize, first open the outer packaging plastic bag, mix the non-woven bag containing the heating agent with water, and immediately heat up. It can generate heat of 130℃ within 1 minute, which can achieve the purpose of full heating and disinfection.

Example Embodiment

[0015] Example 2: Take 5 grams of calcium oxide, 10 grams of diatomaceous earth, 5 grams of activated carbon, 15 grams of salt, and 20 grams of active metals and mix them. After mixing, the oxidative heating reaction occurs, and then it is prepared into a 100 mesh powder heating agent. It is packaged in non-woven bag, externally packaged in an airtight plastic bag, and 100ml of water is packaged in an impermeable packaging bag; when it is necessary to retort and heat the food, first tear the outer packaging plastic bag, and then remove the heat-producing agent. Put the woven bag at the bottom of the cooking and heating lunch box, open the water package, pour the water into the box, quickly put the container with convenience food or meals into the lunch box, the heating package will meet water in 5-8 seconds immediately The temperature is as high as 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...

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...
