Description
Technical field
The invention belongs to the technical field of heating of self-generating exothermal agent and its self-heating food, and in particular to one kind is suitable for high sea
Rise sheer from level ground the self-heating product and preparation method thereof in area.
Background technique
In daily life, existing instant food is dazzling, many kinds of, but these instant food are generally not
With automatic heating device, and taste is better in the state of heating for most of food；Also, there are many people to suffer from indiestion
Encounter cold day and cannot eat food lower than body temperature, therefore facilitate food without automatic heating device to these are eaten for a long time
Product will have a direct impact on the health of people.Especially for some special populations, such as army's camping and field trining, frontier sentry, the people
Alert execution task, flood-fighting, ground observation are investigated, long-distance running, out on tours, and the outdoor activities personnel such as self-driving visitor come
Say, non-transformer, fire source, the flames of anger, without cooking utensils, No Open Flames in the case where to food, article high-temperature heating or
Person is that meet disinfection demand be very difficult.There is the article of spontaneous heating to occur at present, has had the production of many heating agents
Method and device is made public, such as the patent No. 200410012690.9, entitled " a kind of food self-generating exothermal agent and its user
Method ", Formulation Ingredients are made of diatomite, firing diatomite, coke powder, common salt, reduced iron powder mixing；The patent No.
200610127120.3, entitled " a kind of multi-purpose spontaneous heating bag " mainly utilizes roasting diatomite, iron powder, aluminium powder, coke
Powder, active carbon, salt composition；The patent No. 200710019637.5, entitled " a kind of production method of self-heating food " is by aoxidizing
Calcium, electrolysis aluminium powder and alkalinous metal object composition；The purpose of above-mentioned existing patent be for heating food, beverage and for it is other not
There can be the occasion of open firing, formula and preparation method respectively have certain heating feature to varying degrees, normal wild
It can satisfy the demand to heat foods under outer operating environment.Water is the initiator of exothermic reaction in the above spontaneous heating system,
It is simultaneously also the medium of heat transfer, and in high altitude localities, atmosphere, which forces down, causes the boiling point of water lower, therefore, above-mentioned spontaneous heating
Formulation product system temperature can all occurs in high altitude localities and only start to generate a large amount of steam, the temperature of steam at 80 degree or so
Not high and evaporation rate is exceedingly fast, after the reaction the phase, and part metals exothermic mixture does not reach sufficient moisture and is unable to fully react, and leads
Whole calorific value decline is caused, while the water vapour of low temperature is also unable to reach effective heating of food.
Summary of the invention
Based on problem above, it is an object of the invention in view of the deficienciess of the prior art, to provide a kind of fever spontaneous
Hot product is suitable for high altitude localities and uses, and can be generated heat by the high-temperature steam itself generated, reach edible, drinks, sterilizes
Heat purpose.
In order to achieve the goal above, the technical solution adopted by the present invention are as follows: a kind of spontaneous heating suitable for high altitude environment
Product, including exothermic mixture, the exothermic mixture include that weight ratio is (0.8~1.2): (0.03~0.07): the fever group of (2~5)
Divide, release sustaining component, cause component；Wherein, exothermic component includes: calcium hydroxide 10%~55%, carbonate by weight percentage
9%~45%, active metal object 8%~45%, graphite 2%~3%；Release sustaining component is macromolecule polysaccharidase；Cause component to press
Weight percent includes: glycerine 10%~40%, water 60%~90%, wherein each raw material mixing of exothermic component, release sustaining component
After be packaged to obtain heating pack, cause each raw material mixing post package of component and obtain causing packet.
Heating pack provided by the invention, using macromolecule glycan as release sustaining component, after each component is mixed, initiation group
Dividing and a large amount of calcium carbonate and high temperature are reacted and generated with exothermic component, calcium carbonate agglomeration can hinder interior metal to contact with water,
Therefore, sustained release agent is added in the present invention, using the water imbibition of macromolecule glycan, can rapidly be distributed to the moisture caused in component
Exothermic mixture various pieces, meanwhile, macromolecule glycan carries water-swellable at high temperature and constantly destroys system agglomeration, to improve activity
The effecting reaction efficiency of metal object；Initiator of the invention uses the mixture of glycerine and water, reduces system by glycerine
Fusing point improves boiling point, to solve that High aititude severe cold areas air pressure is low, water freezes the defect that can not effectively heat, and improving
Vapor (steam) temperature is also improved while boiling point, glycerine can also make steam with sweet fragrance, cover calcium hydroxide and metal reaction
Peculiar smell.
Preferably, the release sustaining component is at least one of sodium alginate, soluble starch, sodium carboxymethylcellulose
Preferably, the exothermic component includes: calcium hydroxide 35%, carbonate 45%, active metal by weight percentage
Object 18%, graphite 2%.
Preferably, the active metal object is at least one of aluminium powder, magnesium powder.
The present invention also provides the methods using above-mentioned raw materials production heating pack, comprising the following steps:
Step 1 weighs each raw material according to weight percent respectively, spare；
Each raw material of exothermic component is ground into after the powder of 80~150 mesh and mixes with release sustaining component by step 2, will mix
Object is packaged to obtain heating pack；
Step 3 is packaged to obtain initiation packet after mixing each raw material for causing component.
Optimization, use the non-woven bag set gradually from inside to outside, air-locked packaging bag that will generate heat in the step 2
The mixture of component and release sustaining component is sealed up for safekeeping.
Optimization, it is sealed up for safekeeping using fluid-tight packaging bag by component is caused in the step 3.
The invention has the benefit that
(1), heating pack provided by the invention and preparation method thereof uses macromolecule glycan as release sustaining component, utilizes
The water imbibition of macromolecule glycan makes to cause the moisture in component and is rapidly distributed to exothermic mixture various pieces, promotes heating efficiency,
Meanwhile macromolecule glycan carries water-swellable at high temperature and constantly destroys system agglomeration, to improve the effective anti-of active metal object
Answer efficiency；Using the mixture of glycerine and water as initiator, system fusing point is reduced by glycerine, improves boiling point, thus
Solution High aititude severe cold areas air pressure is low, water freezes the defect that can not effectively heat, and also improves while improving boiling point
Vapor (steam) temperature, glycerine can also make steam with sweet fragrance, cover the peculiar smell of calcium hydroxide and metal reaction.
