Embodiment 1

[0009] Particle size of each component of pyrogenic agent:

[0010] Magnesium 30-60 mesh

[0011] Iron 250-320 mesh

[0012] The purity of each component of pyrogenic agent:

[0013] Magnesium 99.5%

[0014] Iron 99.5%

[0015] The weight percent of each component of heating agent:

[0016] Magnesium 70-90%

[0017] Iron 10-30%

[0018] Manufacturing process: The above-mentioned magnesium powder and iron powder with a certain particle size, purity and weight percentage are deformed by calendering, so that small particles of iron powder are embedded in the calendered magnesium to form dispersed granular micro-batteries. Heat agent.

Abstract

Introduce a kind of causing heat agent used for food and the preparation method. magnesium and iron powder in several granularity and quality, under the condition of extrusion to change the shape, the short grained iron powder is bedded into the magnesium which has been tablettized. The causing heat is produced in a shape of local element, which is beaded. The thermal efficiency of the invention is higher, the dose is fewer, craft is easier and cost is lower. All kinds of food in flexible package can be heated up even without heat source and water.

Description

technical field [0001] The invention relates to a chemical heating material, in particular to a formula of a self-heating food heating agent and a preparation method thereof. Background technique [0002] The heating methods of self-heating food can be summarized into two types: one is to use solid fuel to burn and heat the hard cans supported by the grate. Affected by the environment, and soft packaged food cannot be heated. The other is chemical reaction heating food, the product includes three parts: soft package food, heater and medium. When not heating, the heater is isolated from the medium; when heating, the two contact, a chemical reaction occurs, heat is released, and the food is heated through conduction. Representative chemical heating agents at home and abroad mainly include quicklime, iron, aluminum, magnesium and other metal elements, and the medium is water or inorganic salt solution. [0003] 1. Quicklime reacts with water to produce exothermic reaction. ...
