Abstract

The invention discloses a heat generating agent for food heating and a preparation method thereof. The heat generating agent is prepared from calcium oxide, calcium hydroxide, copper oxide, zinc oxide, aluminum, sodium carbonate and sodium bicarbonate, wherein the heat generating agent is prepared from the following components in percentage by weight: 20%-45% of calcium oxide, 1%-10% of calcium hydroxide, 1%-10% of copper oxide, 1%-10% of zinc oxide, 30%-50% of aluminum, 0.1%-10% of sodium carbonate and 5%-19% of sodium bicarbonate. Compared with an existing heat generating agent, the heat generating agent is long in duration time of reaction, non-toxic and harmless, low in price of raw materials, less in dosage and low in manufacturing cost, carrying and quantitative cooking are convenient caused by non-woven bag packaging, and the needs of batch and automated production are further met; since the calcium oxide can easily absorb moisture in air and become the calcium hydroxide, the heat generating agent is not prone to being preserved, under the wrapping of plastic film, long-term preservation is facilitated, so that the heat generating agent is better in stability, and market transportation and popularization are easier; and the heat generating agent is suitable for a wide range of crowds and environment, cooking time is shortened, and cooking conditions are reduced.

Description

technical field [0001] The invention relates to a heating agent and a preparation method thereof, in particular to a heating agent for food heating and a preparation method thereof. Background technique [0002] Exothermic agents usually refer to exothermic agents that use the heat of dissolution or oxidation heat generated by chemical reactions as the heat source to achieve exothermic purposes; exothermic agents are mainly a mixture of aluminum, calcium oxide, copper oxide, and zinc oxide, and often contain Some other add-ons, such as binders and fillers, etc. The rapidity of combustion of the exothermic agent and the heat released during combustion have a decisive influence on its applicability. In addition, its thermal conductivity and melting temperature also affect its applicability; the heating bag (body) made of this heating agent does not require a hot water source compared with the commonly used hot water bag, and the temperature is stable, and you can choose a sui...
