Description
본 발명은 즉석조리식품 조리용 발열체 조성물에 관한 것으로, 보다 구체적으로는 알루미늄(Al), 산화칼슘(CaO), 탄산칼륨(K2CO3) 및 수산화칼슘(Ca(OH)2)을 혼합하여 발열체를 제조함으로써 별도의 조리 장치 없이 수화반응에 따른 열을 이용하여 음식을 조리하거나 뜨겁게 데울 수 있을 뿐만 아니라 장시간 온도를 유지할 수 있는 즉석조리식품 조리용 발열체 조성물에 관한 것이다.The present invention relates to a heating element composition for cooking ready-to-eat food, and more specifically, to a heating element by mixing aluminum (Al), calcium oxide (CaO), potassium carbonate (K 2 CO 3 ) and calcium hydroxide (Ca(OH) 2 ). It relates to a heating element composition for cooking ready-to-cook food, which can not only cook or heat food by using heat according to a hydration reaction without a separate cooking device, but also maintain the temperature for a long time by manufacturing a.
식생활 문화의 발달과 급격한 산업화로 각종 레토르트 포장식품 및 휴대용 인스턴트 식품이 다양하게 개발되고 또한 사용되고 있으며, 최근에는 여러 가지 야외 활동이 활발히 성행하면서 이들의 사용이 급격하게 증가하고 있는 추세이다. 이러한 각종 레토르트 포장식품 및 휴대용 인스턴트식품은 냉장 보관되거나 간단한 처리만으로 먹을 수 있도록 가공되어, 별도의 취사도구를 필요로 하거나 고온의 물을 필요로 하는 문제가 있다.Due to the development of dietary culture and rapid industrialization, various retort packaged foods and portable instant foods are being developed and used in various ways. These various retort-packaged foods and portable instant foods are processed to be eaten by refrigeration or simple processing, and there is a problem in that they require separate cooking utensils or high-temperature water.
특히, 군사적인 목적상의 훈련이나 실제 상황에 있어서 화기를 이용한 취사행위가 거의 불가능하므로 각종 레토르트 포장식품 및 휴대용 인스턴트식품을 사용하고 있지만 상기와 같은 문제점으로 인하여 적당한 식사를 할 수 없어 전력에 큰 차질을 초래하는 경우도 있다.In particular, since it is almost impossible to cook using firearms in military training or actual situations, various retort packaged foods and portable instant foods are used, but due to the above problems, proper meals cannot be eaten, which causes a major setback in power. Sometimes it causes.
종래 발열체들은 몇 가지 금속산화물이나 금속염으로 구성되어 있다. 구체적으로, 생석회(CaO), 수산화칼륨(KOH), 염화칼슘(CaCl2), 염화마그네슘(MgCl2) 등의 화합물을 직접 사용하거나 적절하게 혼합한 혼합물로, 상기 물질을 물이나 수용액과 접촉시킬 때 발생하는 발생열을 이용하는 방법이다.Conventional heating elements are composed of several metal oxides or metal salts. Specifically, compounds such as quicklime (CaO), potassium hydroxide (KOH), calcium chloride (CaCl2), magnesium chloride (MgCl2), etc. are directly used or mixed properly, resulting in the occurrence when the material is brought into contact with water or an aqueous solution. A method using the heat generated.
국내 특허공보 공고번호 제92-210호는 생석회에 약 10 ~ 12%의 염화칼슘을 혼합한 발열체에 20 ~ 30%의 염화마그네슘 용액을 접촉시켜 발생한 순간 발열을 이용하였지만 음식물을 데울 만큼 충분한 발열량을 얻을 수 없다는 단점이 있다.Domestic Patent Publication No. 92-210 uses the instantaneous heat generated by contacting a 20 to 30% magnesium chloride solution to a heating element in which calcium chloride is mixed with quicklime and about 10 to 12%. There is a downside to not being able to.
또한, 국내 특허공보 공개번호 특2000-58524호는 생석회에 2 ~ 35 중량부의 인산용액 (H3PO4)을 접촉시켜 300㎖의 물을 73 ~ 100℃까지 발열시켰으나 오산화인 (P2O4)의 조행성에 의한 맹렬한 수화반응으로 본체인 생석회와 자체 발열반응을 초래하여 유통과정에서 폭발적인 발열반응을 일으킬 위험성을 내포하고 있으며, 게다가 폐기시 인산용액이 생태계에 부영양화를 초래하는 환경 비친화적인 방법이다.In addition, Korean Patent Publication No. 2000-58524 discloses that 2 to 35 parts by weight of a phosphoric acid solution (H3PO4) is contacted with quicklime to heat 300 ml of water to 73 to 100 ° C. The fierce hydration reaction causes a self-heating reaction with the quicklime, which is the main body, and poses the risk of an explosive exothermic reaction in the distribution process. In addition, it is an environmentally unfriendly method because the phosphoric acid solution causes eutrophication to the ecosystem when discarded.
또한, 일본 공개특허공보 소62-9151호에는 생석회에 무기염의 수용액을 접촉시켜 180 ㎖의 음료수를 50℃ 이상으로 가열하는 방법이 개시되어 있다. 상기 방법은 혹한기에 수용액의 결빙을 피할 수 있다는 장점을 지녔지만 역시 음식을 가열하기에는 충분하지 못한 온도이다.Further, Japanese Laid-open Patent Publication No. 62-9151 discloses a method of heating 180 ml of drinking water to 50°C or higher by bringing an aqueous solution of an inorganic salt into contact with quicklime. This method has the advantage of avoiding freezing of the aqueous solution in cold weather, but is also a temperature that is not sufficient to heat food.
한편, 미국 특허번호 제4,7530,85호는 중화반응의 열을 이용한 방법으로 생석회의 수화반응보다는 양호한 열량을 얻을 수 있지만 수산화나트륨(NaOH)과 염산 (HCl)을 이용하기 때문에 취급하는데 매우 위험하다.On the other hand, U.S. Patent No. 4,7530,85 is a method using the heat of the neutralization reaction, which can obtain better heat than the hydration reaction of quicklime, but is very dangerous to handle because it uses sodium hydroxide (NaOH) and hydrochloric acid (HCl). Do.
또한, 미국 특허번호 제4,809,673호는 생석회의 수화반응에 의한 발열반응을 이용한 가열방법으로 약 278 ㎉/g의 열량을 얻을 수 있으나 여전히 식품을 가열하기에는 부족하다.In addition, U.S. Patent No. 4,809,673 is a heating method using an exothermic reaction caused by a hydration reaction of quicklime, and although a calorific value of about 278 kcal/g can be obtained, it is still insufficient to heat food.
다른 방법으로는 미국 특허번호 제5,205,277호에 3가지 가열 패키지로 구성되어 하단부에 열을 발생시키기 위해 생석회를 안치하고, 중간층에는 초산(CH3COOH)과 물, 염화나트륨(NaCl) 용액을 설치하며, 농도가 다른 염화나트륨 용액을 설치하여 용액포의 파열에 따른 생석회의 수화반응열을 유발시킨 후 상단부의 용액에 의한 2차 반응열을 일으키는 방법이 개시되어 있다. 상기 방법은 비교적 높은 온도를 얻을 수 있어서 혹한기나 추운 지방에서는 유용한 방법이나 경제적인 단가가 높아 실용성이 의심된다.As another method, U.S. Patent No. 5,205,277 consists of three heating packages, quicklime is placed in the lower part to generate heat, and acetic acid (CHCOOH), water, and sodium chloride (NaCl) solution are installed in the middle layer, and the concentration is A method of causing heat of hydration of quicklime by installing another sodium chloride solution to cause heat of hydration of quicklime according to rupture of the solution bubble and then generating secondary heat of reaction by the solution at the upper end is disclosed. Since the method can obtain a relatively high temperature, it is a useful method in cold weather or cold regions, but its practicality is doubtful due to its high economical unit price.
또한, 미국 특허번호 제4,522,190호에는 음식물이나 식료품을 가열하기 위한 가열 패키지로 다공성 고분자인 폴리에틸렌을 이용한 초 부식성 금속합금 분말로 구성된 발열체가 개시되어 있다. 초 부식성 마그네슘-철 합금을 바닷물과 같은 전해질 용액과 접촉시켜 비교적 높은 온도를 얻을 수 있지만 가연성이 높고 폭발 위험성이 있는 수소 가스(H2)가 다량 발생하는 단점과 마그네슘-철 합금이 전해질 용액과 매우 느리게 반응하는 취약점이 있다.In addition, U.S. Patent No. 4,522,190 discloses a heating element composed of super-corrosive metal alloy powder using porous polymer polyethylene as a heating package for heating food or foodstuffs. A relatively high temperature can be obtained by contacting the super-corrosive magnesium-iron alloy with an electrolyte solution such as seawater, but it has the disadvantage of generating a large amount of highly flammable and explosive hydrogen gas (H2), and the magnesium-iron alloy reacts very slowly with the electrolyte solution. There are reactive vulnerabilities.
국내 특허출원 제99-46130호는 상기 미국 특허번호 제4,522,190호 및 미국 특허번호 제5,117,809호와 동일한 마그네슘-철 초 부식성 합금을 다른 형태의 가열 패키지로 변화시켰다는 점만 다를 뿐 수소 가스의 발생에 따른 근본적인 폭발 및 화재 위험성과 느린 반응성을 개선하지는 못했다.Korean Patent Application No. 99-46130 differs only in that the same magnesium-iron super-corrosive alloy as in U.S. Patent No. 4,522,190 and U.S. Patent No. 5,117,809 is changed into a different type of heating package, but the fundamental effect of the generation of hydrogen gas It did not improve the explosion and fire hazards and slow responsiveness.
또한, 국내 등록특허 제442560호는 생석회에 3 ~ 15 중량%의 수산화나트륨 무수물, 3 ~ 15 중량%의 알칼리금속산화물, 3 ~ 15 중량%의 알루미늄 금속, 3 ~ 15 중량%의 산성염을 혼합하여 물이나 전해질 용액과 접촉시켜 350㎖의 물을 85 ~ 100℃까지 발열시켰으나, 공기 중의 수분을 80% 이상 흡수하는 생석회를 이용함에 따라 장기간보관 시 쉽게 산화하여 수화반응에 따른 가열온도가 현저하게 떨어지고 반응 시작시간이 늦어지는 문제가 있다.In addition, Korean Registered Patent No. 442560 is a mixture of 3 to 15% by weight of sodium hydroxide, 3 to 15% by weight of alkali metal oxide, 3 to 15% by weight of aluminum metal, and 3 to 15% by weight of acid salt in quicklime. 350ml of water was heated up to 85 ~ 100℃ by contacting with water or an electrolyte solution, but as quicklime, which absorbs more than 80% of moisture in the air, is easily oxidized during long-term storage, the heating temperature due to the hydration reaction is remarkably lowered.

이하 본 발명을 보다 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail.
본 발명에서는 92% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 산화칼슘(CaO) 44 내지 54 중량%; 99.7% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 알루미늄(Al) 34 내지 42 중량%; 91% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 탄산칼륨(K2CO3) 6 내지 12 중량% 및 91% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 수산화칼슘(Ca(OH)2) 5 내지 15 중량%로 이루어진 것을 특징으로 하는 즉석조리식품 조리용 발열체 조성물을 제공한다. In the present invention, 44 to 54% by weight of calcium oxide (CaO) having a purity of 92% or more and a particle size of 0.4 to 0.6 mm; 34 to 42% by weight of aluminum (Al) having a purity of 99.7% or more and a particle size of 0.4 to 0.6 mm; Potassium carbonate (K 2 CO 3 ) having a purity of 91% or more and a particle size of 0.4 to 0.6 mm 6 to 12% by weight and calcium hydroxide (Ca(OH) 2 ) having a purity of 91% or more and a particle size of 0.4 to 0.6 mm 5 to 12% by weight It provides a heating element composition for cooking ready-to-eat food, characterized in that it consists of 15% by weight.
본 발명의 즉석조리식품 조리용 발열체 조성물의 필수 구성성분인 산화칼슘(CaO)을 물과 반응시키기 위해서는 알루미늄(Al)을 필요로 하는데, 산화칼슘과 알루미늄을 물과 함께 반응시키면 2~3분 후 고온의 가스와 함께 높을 열량을 내면서 반응한다. 즉, 산화칼슘은 알루미늄과 함께 수화 반응하여 반응 초기 열량을 보존하며, 다른 성분의 지속적인 반응 연결을 가능케 한다. In order to react calcium oxide (CaO), which is an essential component of the heating element composition for cooking ready-to-eat food according to the present invention, with water, aluminum (Al) is required. It reacts with high-temperature gas, producing high heat. That is, calcium oxide undergoes a hydration reaction with aluminum to conserve the initial heat of reaction, and enables continuous reaction connection of other components.
상기 알루미늄 분말은 수산화칼슘과 반응하며 물에 용해되어 조성물의 온도를 높이고 다른 성분들의 반응을 도와 발열체 조성물이 함께 화합하여 반응하도록 한다. 알루미늄과 수산화칼슘은 반응하여 알루민산칼슘을 형성하는 반응열은 휴대용 포장식품을 가열하는데 충분한 열원이 될 수 있다.The aluminum powder reacts with calcium hydroxide and dissolves in water to increase the temperature of the composition and to help the reaction of other components to combine and react with the heating element composition. The heat of reaction in which aluminum and calcium hydroxide react to form calcium aluminate can be a sufficient heat source for heating portable packaged food.
상기 산화칼슘은 즉석조리식품 조리용 발열체 조성물 총 중량을 기준으로 하여 44 내지 54 중량%의 양으로 사용되는 것을 특징으로 한다. 이 때 상기 산화칼슘의 양이 44 중량% 미만일 경우에는 발열 효능이 떨어지고, 산화칼슘의 양이 54 중량%를 초과할 경우에는 상대적으로 알루미늄의 양이 적어져서 열량이 부족하여 다른 염기 성분의 반응이 원활하지 않다.The calcium oxide is characterized in that it is used in an amount of 44 to 54% by weight based on the total weight of the heating element composition for cooking ready-to-eat food. At this time, when the amount of calcium oxide is less than 44% by weight, the exothermic efficacy is lowered, and when the amount of calcium oxide exceeds 54% by weight, the amount of aluminum is relatively small, so that the reaction of other basic components is insufficient due to insufficient heat. It's not smooth.
상기 알루미늄 (Al) 금속분말은 34 내지 42 중량%의 범위로 첨가되는 것이 바람직한데, 이 때 알루미늄이 34 중량% 미만으로 첨가되면 열량이 부족하여 다른 염기 성분의 반응이 원활하지 않으며, 온도가 저하되고, 42 중량% 초과의 양으로 첨가되면 고온을 발생시키지만 반응 시간이 너무 짧고, 다른 염기 성분의 첨가량이 줄어 온도 유지 시간이 짧아지는 문제가 있다.The aluminum (Al) metal powder is preferably added in the range of 34 to 42% by weight. At this time, when aluminum is added in less than 34% by weight, the reaction of other basic components is not smooth due to insufficient heat, and the temperature is lowered. And, when added in an amount of more than 42% by weight, a high temperature is generated, but the reaction time is too short, and the addition amount of other basic components is reduced, resulting in a short temperature holding time.
이 때, 알루미늄(Al)은 99.7% 이상의 순도와, 0.4~0.6㎜의 입도를 가지며, 산화칼슘(CaO)은 92% 이상의 함량과, 0.4~0.6㎜의 입도를 갖는다.At this time, aluminum (Al) has a purity of 99.7% or more and a particle size of 0.4 to 0.6 mm, and calcium oxide (CaO) has a content of 92% or more and a particle size of 0.4 to 0.6 mm.
상기 탄산칼륨(K2CO3)은 무수탄산칼륨이라고도 하며 비누, 유리, 의약품 등의 원료이다. 천연으로는 나뭇재에 다량 함유되어 있어 잿물로 추출되며, 밀가루 등의 식품에 점성 및 탄력성을 증가시키고, 물에는 녹지만 에탄올에는 녹지 않고 수용액은 알칼리성을 나타낸다. 각종의 산과 반응하여 염을 형성하며, 팽창제, 산도조절제로 사용된다.The potassium carbonate (K 2 CO 3 ) is also called anhydrous potassium carbonate and is a raw material for soap, glass, pharmaceuticals, and the like. It is naturally contained in wood ash, so it is extracted with lye, increases the viscosity and elasticity of foods such as flour, and is soluble in water but insoluble in ethanol, and its aqueous solution is alkaline. It reacts with various acids to form salts, and is used as a swelling agent and acidity regulator.
상기 탄산칼륨(K2CO3)은 6 내지 12 중량% 범위로 첨가되는 것이 바람직한데, 이 때 탄산칼륨이 6 중량% 미만으로 첨가되면 용기의 점성이 유지되지 않아 발열체 조성이 어려우며, 12 중량% 초과의 양으로 첨가되면 발열체 팽창이 증대하여 과도한 발열로 위험할 수 있다. 탄산칼슘은 발열 후 고온 유지 시간을 길게 하기 위해 포함된다.The potassium carbonate (K 2 CO 3 ) is preferably added in an amount of 6 to 12% by weight. At this time, when potassium carbonate is added in an amount of less than 6% by weight, the viscosity of the container is not maintained, making it difficult to form a heating element. If added in an excessive amount, the expansion of the heating element increases, which can be dangerous due to excessive heat generation. Calcium carbonate is included to lengthen the high-temperature holding time after exothermic heat.
상기 수산화칼슘(Ca(OH)2)은 알루미늄 분말과 함께 물과 접촉시 수화반응하여 반응 초기 열량을 보존하고 다른 성분들의 지속적인 반응의 연결을 가능하게 한다.The calcium hydroxide (Ca(OH) 2 ) reacts with hydration upon contact with water together with the aluminum powder, thereby preserving the initial energy of the reaction and enabling continuous reaction of other components.
상기 수산화칼슘은 5 내지 15 중량%의 범위로 첨가되는 것이 바람직한데, 이 때 수산화칼슘이 5 중량% 미만으로 포함되면 알루미늄 분말과 반응시 반응유지 시간이 짧고 충분한 열량을 발생하지 못하며, 15 중량%를 초과하여 포함되면 알루미늄 분말과 반응시 충분히 용해되지 못하여 양에 비해 충분한 열량을 내지 못한다.The calcium hydroxide is preferably added in the range of 5 to 15% by weight. At this time, when calcium hydroxide is included in less than 5% by weight, the reaction holding time is short and sufficient heat is not generated when reacting with aluminum powder, and the amount exceeds 15% by weight. If it is included, it is not sufficiently dissolved when reacting with aluminum powder, so it does not produce a sufficient amount of heat compared to the amount.
본 발명의 하나의 구현예에 따르면, 본 발명에 따른 즉석조리용 발열체 조성물은 탄산칼슘(CaCO3)을 즉석조리용 발열체 조성물의 총 100 중량부를 기준으로 하여 8 내지 15 중량부의 양으로 첨가할 수 있다.According to one embodiment of the present invention, the heating element composition for instant cooking according to the present invention may add calcium carbonate (CaCO 3 ) in an amount of 8 to 15 parts by weight based on a total of 100 parts by weight of the heating element composition for instant cooking. there is.
상기 탄산칼슘(CaCO3)은 물에는 거의 녹지 않지만 이산화탄소가 녹아 있는 물에는 잘 녹는다. 탄산칼슘은 알루미늄 분말과 수산화칼슘이 물과 1차로 반응하여 생성되는 탄산이온과 반응하여 탄산수소칼슘(Ca(HCO3)2)을 생성하는 중화반응을 수행한다. 이러한 탄산수소칼슘은 물에 잘 용해되어 발열체 조성물의 반응을 돕는다. 탄산수소칼슘을 생성하는 탄산칼슘의 중화반응은 느린 반응이므로 발열 후 급격한 온도 하락을 방지하여 고온 유지 시간을 길게 한다.The calcium carbonate (CaCO 3 ) is hardly soluble in water, but is well soluble in water in which carbon dioxide is dissolved. Calcium carbonate reacts with carbonate ions generated by the primary reaction of aluminum powder and calcium hydroxide with water to perform a neutralization reaction to produce calcium hydrogen carbonate (Ca(HCO 3 ) 2 ). Such calcium bicarbonate is well soluble in water and helps the reaction of the heating element composition. Since the neutralization reaction of calcium carbonate producing calcium bicarbonate is a slow reaction, a rapid temperature drop is prevented after exothermic heat, and the high temperature holding time is lengthened.
본 발명의 하나의 구현예에 따르면, 본 발명의 발열체 조성물 100 중량부에 대해 250 ~ 300 중량부의 물을 부가하여 수화반응 및 중화반응에 의한 반응열이 발생하도록 하는데, 물은 상기 혼합 조성물들과 반응하여 열을 발생하는 것으로, 수화반응의 주요 성분이고, 물의 양을 250 중량부 미만로 하면 수화반응이 제대로 발현되지 아니하며, 300 중량부를 초과하면 과다하여 반응이 제대로 일어나지 아니하게 된다.According to one embodiment of the present invention, 250 to 300 parts by weight of water is added to 100 parts by weight of the heating element composition of the present invention to generate heat of reaction due to hydration and neutralization, and water reacts with the mixed compositions. It is a major component of the hydration reaction by generating heat, and if the amount of water is less than 250 parts by weight, the hydration reaction is not properly expressed, and if it exceeds 300 parts by weight, the reaction is excessive and the reaction does not occur properly.
본 발명의 하나의 구현예에 따르면, 본 발명에 따른 즉석조리식품 조리용 발열체 조성물은 92% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 산화칼슘(CaO) 48 중량%; 99.7% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 알루미늄(Al) 38 중량%; 91% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 탄산칼륨(K2CO3) 8 중량% 및 91% 이상의 순도 및 0.4~0.6㎜의 입도를 갖는 수산화칼슘(Ca(OH)2) 6 중량%로 이루어진 것이 특징이다.According to one embodiment of the present invention, the heating element composition for cooking ready-to-eat food according to the present invention includes 48% by weight of calcium oxide (CaO) having a purity of 92% or more and a particle size of 0.4 to 0.6 mm; 38% by weight of aluminum (Al) having a purity of 99.7% or more and a particle size of 0.4 to 0.6 mm; 8% by weight of potassium carbonate (K 2 CO 3 ) having a purity of 91% or more and a particle size of 0.4 to 0.6 mm and 6% by weight of calcium hydroxide (Ca(OH) 2 ) having a purity of 91% or more and a particle size of 0.4 to 0.6 mm It is characterized by being made.
그리고, 발열체 조성물을 이중 용기에 넣고, 여기에 물 400㎖를 투입한 후 이중 용기를 밀폐한 후 측정해 본 결과 발열체 내부 온도가 2분경 바로 발열하여 4분경에는 100℃ 이상으로 발열되고, 밀폐된 이중 용기 내에서 120℃ 이상으로 25 내지 27분 동안 발열하게 되며, 총 반응시간은 30분간 유지하였다.In addition, the heating element composition was put into a double container, 400 ml of water was added thereto, and the double container was sealed and measured. In the double vessel, heat was generated at 120° C. or higher for 25 to 27 minutes, and the total reaction time was maintained for 30 minutes.
