황토숯가마를 이용한 천일염의 정제방법{SOLAR EVAPORATING PROCESS USING OCHER CHARCOAL KETTLE}SOLAR EVAPORATING PROCESS USING OCHER CHARCOAL KETTLE}

본 발명은 황토숯가마를 이용한 천일염의 정제방법에 관한 것으로, 더욱 구체적으로는 황토숯가마에서 숯을 구워낸 다음 그 열기가 일정온도를 유지할때 천일염을 투입하여 가열할수 있게 하므로서 천일염내에 포함되어 있는 중금속등의 불순물이 제거되고 순화되어 부드럽고 맛이 좋은 양질의 천일염을 얻는 것인데 이렇게하므로서 숯을 구워낸 황토가마의 열기를 천일염정제에 이용하므로서 경제적인 이점이 있도록 한 것이다.The present invention relates to a refining method of sun salt using an ocher charcoal kiln, and more specifically, after baking charcoal in an ocher charcoal kiln, the heat is added to the sun salt when the heat is maintained at a constant temperature, such as heavy metals contained in the sun salt. The impurities are removed and purified to obtain a soft and delicious high-quality sun salt, which is an economic advantage by using the heat of the ocher kiln baked charcoal in the sun salt tablet.

일반적으로 소금은 염화나트륨(Nacl)을 주성분으로 하여 수분, 칼슘, 마그네슘, 칼륨등이 함유되어 있으며 짠맛이 나는 흰결정체로서 물에 녹으면 전해되어 나트륨이온Na+과 염소이온Cl-으로 해리되는 강한 전해질이며, 800℃이상이 되면 녹아서 액체가 되고 1400℃이상이 되면 기체가 되는 성질이 있고, 인체에는 생리적으로 필수적인 요소이다.Generally, salt is composed of sodium chloride (Nacl) and contains moisture, calcium, magnesium and potassium. It is a salty white crystal. It is a strong electrolyte that is dissolved when dissolved in water and dissociated into sodium ions Na + and chlorine ions Cl-. When it is over 800 ℃, it melts and becomes liquid, and when it is over 1400 ℃, it becomes gas. It is physiologically essential for human body.

그리고 소금의 종류에는 천일염과 암염, 정제염, 재제염, 가공염등이 있으며그 제조방법은 다음과 같다.Types of salt include sun salt, rock salt, refined salt, recontaminated salt, processed salt, etc. The production method is as follows.

천일염은, 태양열, 바람등 자연을 이용하여 해수를 저류지로 유입해 자연증발시켜서 만들고 있으며 염도는 일반적으로 약 80∼90%이다.Solar salt is made by inducing the natural evaporation of seawater into the reservoir by using nature such as solar heat and wind, and the salinity is generally about 80 ~ 90%.

암염은, 천연으로 땅속에 층을 이루고 파묻혀 있던 것을 제염한 것으로 분쇄, 선별, 가공되어 공업용과 식용으로 널리 사용되며 염도가 96%이상이다.Rock salt is a salt that is naturally layered and buried in the ground. It is crushed, sorted and processed, and is widely used for industrial purposes and food. It has a salinity of more than 96%.

정제염은, 바닷물을 여과조에 담아 Na+이온과 Cl-이온만을 전기분해하고 농축함수를 증발관에 넣어 수분을 증발시켜 이것을 원심분리기에 넣은 후 수분 0.01%로 건조기에서 완전 건조하여 만든 것으로 염화나트륨의 순도를 99%이상으로 높은 것으로서 마그네슘이 제거되어 흡습성이 적다.Purified salt is made by electrolyzing only Na + ions and Cl- ions by putting sea water in a filtration tank, adding a concentrated function to an evaporation tube to evaporate water, putting it in a centrifuge, and drying it completely in a dryer with 0.01% moisture. As high as 99% or higher, magnesium is removed and the hygroscopicity is low.

재제염은, 원료소금을 용해, 탈수, 건조등의 과정을 거쳐 다시 재결정화시켜 제조한 것으로 보통 천일염 약20%와 수입염 약80%를 섞어 110∼120℃로 18∼20시간 동안 가열하여 만든 것으로 염도는 90%이상으로 높다.Re-desalting is made by recrystallizing raw salt after dissolving, dehydrating and drying. It is usually made by mixing about 20% of natural salt and about 80% of imported salt and heating it at 110-120 ℃ for 18-20 hours. Is higher than 90%.

가공염은, 원료소금을 볶음, 태움, 용융등의 방법으로 변형한 소금 또는 식품첨가물을 넣어 가공한 소금이다.Processed salt is salt which is processed by adding raw material salt or food additives transformed by roasting, burning or melting.

상기와 같은 소금중에서 인체에 유익한 미네랄성분이 함유된 천일염을 식염으로 많이 사용하고 있으나 천일염은 최근의 산업화등에 의해 바닷물이 각종 오염물질로 더럽혀지면서 중금속등의 불순물이 포함되는 문제점이 있었다.Among the salts described above, sun salt, which contains minerals beneficial to the human body, is used a lot as salt, but sun salt has a problem that impurities such as heavy metals are contained as seawater is polluted with various pollutants by recent industrialization.

이상과 같은 문제점을 감안하여 천일염에서 불순물을 제거하는 수단으로 400∼450℃에서 1∼4시간 구워 유기물과 비소를 제거하는 1단계공정과, 550∼600℃에서 30분∼4시간 구워 비소, 산화물, 카드뮴을 제거하는 2단계공정과, 700∼800℃에서 30분∼4시간 구워 납, 내화성유기물, 칼슘, 마그네슘등 산화물을 제거하는 3단계 공정을 통해 유해물질을 제거하고 있으나 인체에 유익한 미네랄도 함께 제거될 뿐만 아니라 소금이 타게되어 색깔이 변하게 되고 생산공정에 따른 에너지(스팀, 전기)가 많이 소비되는 문제점이 있었다.In view of the above problems, as a means of removing impurities from natural salts, baking is performed for 1 to 4 hours at 400 to 450 ° C. to remove organic matter and arsenic; and baking for 30 minutes to 4 hours at 550 to 600 ° C. for arsenic and oxide It removes harmful substances through two-step process to remove cadmium and three-step process to remove oxides such as lead, refractory organic matter, calcium and magnesium by baking for 30 minutes to 4 hours at 700 ~ 800 ℃. In addition to being removed together, the salt is burned, the color changes, and there is a problem that energy (steam, electricity) is consumed according to the production process.

본 발명은 이러한 문제점을 해결하기 위하여 황토숯가마내부의 잔유열기를 이용하여 천일염을 정제하는 것인데 숯을 구워낸 후의 숯가마열기를 이용하는 것이 특징이다.The present invention is to purify the sun salt using the residual heat burner in the loess charcoal kiln in order to solve this problem is characterized by using the charcoal kiln after burning the charcoal.

황토숯가마는 주벽이 황토로 구축되어 있고 숯을 제조하려면 상당시간을 1300℃이상 유지해야하므로 숯을 만든 직후의 열기로 상당한 온도를 유지하게 되고 원적외선이 많이 방출되는 특징이 있다.Ocher charcoal kiln is the main wall is made of ocher, and to prepare the charcoal to maintain a considerable time more than 1300 ℃, it is characterized by maintaining a considerable temperature by the heat immediately after making the charcoal and emits a lot of far infrared rays.

By removing and purifying the contained impurities, the salt is activated by the far-infrared radiant heat radiated from the yellow soil to produce a soft and welcome natural salt.

황토숯가마내부에 나무를 차곡차곡 쌓고 불쏘시개를 넣어 자발탄화시키고 탄화가 끝난후 황토가마를 열어 공기를 넣고 그 안의 가스를 태우면서 온도를 1000℃이상으로 올려 새빨갛게 탄화가되면 숯을 꺼내 축축한 흙과 숯가루가 섞인 재속에 넣어 불을 끄면 백탄이 되고 황토가마내부에서 불이 자연적으로 꺼지게 한뒤 꺼내면 검탄이 되는 방법으로 숯을 제조하게 되는데 이러한 과정으로 인해 황토숯가마에는 고온이 유지되면서 황토에서 원적외선이 충분히 방출되게 되는 것이다.The wood is piled up inside the ocher charcoal kiln and spontaneously carbonized with a fire plug. After the carbonization, open the ocher kiln, add air and burn the gas in it to raise the temperature above 1000 ℃. The charcoal is mixed with charcoal powder to turn off the fire and become charcoal. The fire is naturally turned off from the inside of the ocher kiln. Will be released.

따라서 본 발명은 황토숯가마 내부온도가 약300∼350℃로 하강하면 내열성 비금속용기(질그릇)에 담은 천일염을 상기 황토가마내부에 넣어, 출입구를 밀봉시킨 다음 약22∼24시간 동안 열기를 가해 천일염을 정제하는 것이다.Therefore, in the present invention, when the internal temperature of the ocher charcoal kiln is lowered to about 300 to 350 ° C., the sun salt is placed in the ocher kiln in a heat-resistant nonmetallic container, and the entrance is sealed, and then heat is applied for about 22 to 24 hours. To refine.

이러한 본 발명은 황토숯가마로 숯을 구워내고 숯을 구워내면서 가열된 온도에 의해 달구어진 숯가마의 열기와 그 내부에서 방출되는 원적외선을 이용하는 것이므로 황토숯가마 내부열기가 300∼350℃ 온도로 하강된 상태로 천일염을 투입하면 천일염이 타지 않고 가마내의 열기에 의거 각종 불순물을 제거하게 되고 황토에서 방사되는 원적외선에 의해 소금이 활성화되어 부드럽고 맛이 좋게 된다.The present invention is to use the heat of the charcoal kiln baked by the heated temperature while baking charcoal with ocher charcoal kiln and far-infrared rays emitted from the inside of the ocher charcoal kiln internal heat is lowered to 300 ~ 350 ℃ temperature state When sun salt is added, sun salt does not burn, and various impurities are removed by the heat in the kiln, and salt is activated by far-infrared rays emitted from ocher, so that the taste is soft and delicious.
