Abstract
The invention relates to a non-flame heating agent and pertains to food heating field, components and weight ratios of the invention are: 8-20 portions of sodium sulfate or sodium chloride, 4-16 portions of sodium hydroxide or potassium hydroxide, 30-80 portions of calcium oxide and 3-12 portions of aluminum powder. The heating agent of the invention has fast and high temperature raise and long heating continuous time, thus resulting in fully heating of the food; meanwhile, residue of applied heating agent is solidified into blocks, thereby reducing pollution of solid particles in the air and protecting environment effectively.
Description
Technical field
The present invention relates to food heating field, particularly relate to a kind of non-flame heat-generating agent.
Background technology
The raising of urban life rhythm makes the urban work person yearn for very much the comfortable environment of the Nature, but in order to protect environment, a lot of countrysides are no naked lights all, make that outer suburbs traveller's life is very inconvenient, can only instant food.A kind of flame-less heating food heating bag occurred on the market now, its main raw material is unslaked lime, aluminium powder, sodium hydroxide, inorganic salt etc. are major ingredient, as long as this kind heating bag adds entry, hydration reaction can take place, emit heat and heat packed food.But on the market be that the heat-generating agent of main component is because its composition proportion is improper with the above-mentioned raw materials, its heating temp is not high, heating continuing time is not long, make that the packed food heating is not saturating, do not reach the purpose of heated food, mostly heat-generating agent is Powdered ashes after reaction is finished simultaneously, flies upward with the wind easily, causes environmental pollution.
Summary of the invention
The present invention is directed to the defective in the above-mentioned field, a kind of non-flame heat-generating agent is provided, have the heating temp height, the characteristics that heating continuing time is long do not produce dust pollution to environment simultaneously.
A kind of non-flame heat-generating agent, its composition and weight part are: sodium sulfate or sodium-chlor 8-20 part, sodium hydroxide or potassium hydroxide 4-16 part, calcium oxide 30-80 part, aluminium powder 3-12 part.
Preferably: sodium sulfate or sodium-chlor 10-15 part, sodium hydroxide or potassium hydroxide 5-10 part, calcium oxide 40-60 part, aluminium powder 5-10 part.
More preferably: 15 parts in sodium sulfate, 8 parts in sodium hydroxide, 50 parts in calcium oxide, 8 parts of aluminium powders.
The using method of above-mentioned non-flame heat-generating agent, the water that adds 20-68 part in raw material gets final product.
Non-flame heat-generating agent of the present invention is to pack into after above-mentioned raw materials is prepared to be bundled into pouch in the non-woven fabrics, adds water during use and gets final product.Compare with the heat-generating agent on the market, its set of dispense makes its heating temp height than more reasonable, and longer duration owing to strengthened the content of calcium oxide, makes the raw material that reacts after finishing be solidified into piece, rather than becomes powder simultaneously, has reduced the pollution of environment.Raw material is after adding entry in the non-flame heat-generating agent of the present invention, at first is that sodium hydroxide or potassium hydroxide are dissolved in and belong to thermopositive reaction in the water, caused the thermopositive reaction of all the other raw materials of the present invention.Sodium hydroxide or potassium hydroxide are soluble in water, make water be strong basicity, emit a large amount of heats with aluminium powder generation hydration reaction, and heating temp is raise rapidly, reach very soon more than 100 degree.Calcium oxide is soluble in water also to be that a thermopositive reaction generates calcium hydroxide, react with carbon dioxide in air simultaneously, generate water-fast lime carbonate, because the content of calcium oxide is bigger and speed above-mentioned two reactions are all slower, provide thermal source for heat-generating agent continues heat release, the lime carbonate that reaction simultaneously generates is water insoluble and be solidified into piece.Sodium sulfate or sodium-chlor can absorb airborne moisture in the raw material, make heat-generating agent of the present invention be unlikely to influence because of the moisture absorption exothermic reaction before use.All raw materials all adopt food grade materials safe and reliable to the people.
Sodium hydroxide and potassium hydroxide all are highly basic in the present invention's prescription, soluble in waterly emit a large amount of heats, guaranteed the start-up temperature of heat-generating agent generation combination reaction, its consumption is suitable with the aluminium powder consumption simultaneously, make the hydration reaction of aluminium powder produce unnecessary waste material fully and not, and the consumption height of other products on the amount ratio market of calcium oxide guarantee that this heat-generating agent continues heat release, and finally be solidified into piece, avoid environment is produced pollution.
