Self-heating product applicable to high-altitude environment and manufacturing method thereof

Abstract

The invention provides a self-heating product applicable to a high-altitude environment. The self-heating product is characterized by comprising a heat-generating agent which comprises a heat-generating component, a sustained-release component and an initiating component in a weight ratio of (0.8-1.2): (0.03-0.07): (2-5), wherein the heat-generating component comprises, in percentages by weight, 10% to 55% of calcium hydroxide, 9% to 45% of carbonate, 8% to 45% of an active metal substance and 2% to 3% of graphite; the sustained-release component is macromolecular polysaccharide; the initiating component comprises, in percentages by weight, 10% to 40% of glycerol and 60% to 90% of water; the raw materials of the heat-generating component and the sustained-release component are mixed and packaged to obtain a heat-generating package; and the raw materials of the initiating component are mixed and packaged to obtain an initiating package. The self-heating product provided by the inventioncan generate heat through self-generated high-temperature steam to achieve the heating purposes of eating, drinking, disinfection, etc.

Description

technical field [0001] The invention belongs to the technical field of heating self-heating agents and self-heating foods, and in particular relates to a self-heating product suitable for high-altitude areas and a production method thereof. Background technique [0002] In daily life, the existing convenience food is full of beautiful things in eyes and various in variety, but these convenience foods generally do not have an automatic heating device, and most of the food tastes better when heated; People run into cold weather and can not eat the food that is lower than body temperature, therefore eat these convenience foods that do not have automatic heating device for a long time, can directly affect people's health. Especially for some special groups of people, such as military camping training, border guard posts, civilian police performing tasks, flood fighting and emergency rescue, field exploration and investigation, long-distance driving, traveling, self-driving touri...

Problems solved by technology

[0005] The heating pack provided by the present invention adopts high-molecular polysaccharide as the slow-release component. When the components are mixed, the initiating component reacts with the heating component and generates a large amount of calcium carbonate and high temperature. Calcium carbonate agglomeration will hinder internal The metal is in contact with water. Therefore, the present invention adds a slow-release agent, and utilizes the water absorption of the polymer polysaccharide to quickly disperse the moisture in the triggering component to each part of the heating agent. At the same time, the polymer polysaccharide releases water at high temperature. Swell and continuously destroy the system agglomeration, thereby improving the effective reaction efficiency of active metals; the initiator of the present invention uses a mixture of glycerin and water, and lowers the melting point of the system through glycerin and increases the boiling point, thereby solving the problem of air pressure in high-altitude alpine regions. Low temperature, the defect that water freezing cannot be heated effectively, and the steam temperature is also increased while increasing the boiling point. Glycerol can also make the steam accompanied by a sweet aroma, and cover up the peculiar smell of the reaction between calcium hydroxide and metal
