Abstract
Description
본 발명은 소금의 정제 방법에 관한 것이다. 소금은 일반적으로 해수로부터 만들어지는데, 해수에는 여러 가지의 인체에 유익한 성분 즉, 칼륨, 칼슘, 마그네슘, 아연, 철, 인, 나트륨, 망간 등의 미네랄성분이 있을 뿐만 아니라 인체에 유해한 성분인 염화 마그네슘, 염산, 황산 등도 많이 함유되어 있다. 따라서 해수를 햇볕으로 수분을 증발시켜 만든 천일염(天日鹽)이나 해수를 가열하여 건조시키거나 해수를 분사시키면서 열풍으로 건조시켜 만든 해수염(海水鹽)은 해수의 오염등으로 불순물이 많이 함유되어 있기 때문에 이를 정제해야 식염으로 사용할 수 있다. 종래의 소금의 정제방법은 천일염 등을 물에 녹였다가 재결정시키거나, 천일염을 1000℃ 정도로 가열하여 용융시킨 다음 불순물을 제거한 후 냉각하여 정제된 소금을 제조하였다. 그러나 전자의 방법은 불순물이 충분히 제거되지 못하는 결점이 있고 후자의 방법은 불순물은 충분히 제거할 수 있으나 100℃ 정도의 고온으로 가열해야 하기 때문에 번거롭고 또한 인체에 유익한 미네랄 성분도 모두 제거되는 결점이 있었다. 본 발명은 종래의 결점을 해결하기 위한 것으로 천일염이나 해수염을 400℃ 내지 800℃로 가열 처리함으로써 불순물만을 제거하고 인체에 유익한 미네랄 성분이 함유된 정제된 소금을 제공하기 위한 것이다. 이하 본 발명을 상세히 설명한다. 천일염이나 해수염을 로(爐)에 투입하고 가열하면 섭씨 150℃∼200℃에서 소금의 색깔이 점차 누렇게 된다. 이와 같은 현상은 간수 성분인 염화 마그네슘이 인체에 무해한 산화마그네슘으로 변하면서 생기는 현상이다. 계속 가열하면 200℃ 내지 450℃에서 소금은 검은 색깔로 변하면서 가스가 방출되기 시작하고 450℃ 내지 550℃에서 인체에 유해한 성분이 기체화되어 방출되면서 소금은 약간 누런 색깔로 변한다. 450℃ 내지 550℃를 유지하면서 30분 내지 1시간 동안 충분히 유해성분을 방출시켜 1단계 가열을 행한 후, 다시 온도를 높여 550℃ 내지 600℃에서 30분 내지 1시간 동안 2단계 가열을 행한다. 2단계 가열에서 잔류된 유해가스를 제거하면 점차 소금은 다시 백색으로 되돌아간다. 그 다음 다시 600℃ 내지 800℃에서 30분 내지 1시간 동안 3단계 가열을 행함으로써 순백색 내지 미백색의 미네랄 성분이 함유된 정제된 소금을 얻는다. 이때 소금이 용해되지 않는 온도범위내에서 3단계 가열을 행함으로써 불순물을 제거하고 미네랄 성분이 함유된 소금을 얻는 방법으로서 본 발명의 방법에 의해 정제된 소금은 맛이 짠맛이 나면서도 뒷맛이 매우 고소한 특징이 있다. 본 발명에 의한 소금은 종래의 물에 녹였다가 재결정하는 정제방법에 의한 소금보다 불순물이 적고 100℃이상의 온도를 용융시켜 정제한 소금보다 미네랄 성분이 많이 함유되는 장점이 있다. 이하 본 발명을 실시예로서 상술한다.The present invention relates to a method for purifying salt. Salt is generally made from sea water, which contains not only minerals such as potassium, calcium, magnesium, zinc, iron, phosphorus, sodium, and manganese, but also magnesium, which is harmful to humans. It also contains a lot of hydrochloric acid and sulfuric acid. Therefore, sea salt (天日 鹽) made by evaporating water in the sun or sea water is heated or dried, or sea salt made by drying with hot air while spraying sea water contains a lot of impurities due to contamination of sea water. Because it is purified, it can be used as a salt. Conventional salt refining method is to dissolve the natural salt in water and recrystallized, or the natural salt is heated to about 1000 ℃ to melt and remove the impurities to cool to prepare a purified salt. However, the former method has a drawback in that impurities are not sufficiently removed, and the latter method has a drawback in that it is possible to remove the impurities sufficiently, but it is cumbersome because all the minerals beneficial to the human body need to be heated to a high temperature of about 100 ° C. The present invention is to solve the drawbacks of the prior art is to provide a purified salt containing a mineral component beneficial to the human body by removing only impurities by heating the natural salt or sea salt to 400 ℃ to 800 ℃. Hereinafter, the present invention will be described in detail. When salt and sea salt are added to the furnace and heated, the color of salt gradually becomes yellow at 150 ℃ ~ 200 ℃. This phenomenon occurs when magnesium chloride, which is a constituent of the brine, is changed into magnesium oxide, which is harmless to the human body. If the heating continues, the salt turns black at 200 ° C. to 450 ° C., and the gas starts to be released. At 450 ° C. to 550 ° C., harmful ingredients are vaporized and released, and the salt turns slightly yellow. While maintaining the 450 ℃ to 550 ℃ to release the harmful components for 30 minutes to 1 hour sufficiently to perform a one-step heating, and then raise the temperature again and perform two stage heating for 30 minutes to 1 hour at 550 ℃ to 600 ℃. When the harmful gas remaining in the two-stage heating is removed, the salt gradually returns to white. Then, three steps of heating for 30 minutes to 1 hour at 600 DEG C to 800 DEG C are further performed to obtain purified salts containing pure white to white white mineral components. At this time, the salt purified by the method of the present invention is a method of removing impurities by performing three-stage heating within a temperature range in which salt does not dissolve and obtaining a salt containing mineral components. There is a characteristic. Salt according to the present invention has the advantage that less impurities than salt by the refining method to dissolve in water and re-crystallized in the prior art and contains more mineral components than the salt purified by melting the temperature of 100 ℃ or more. Hereinafter, the present invention will be described in detail by way of examples.
[실시예 1]Example 1
천일염 300kg을 노에 투입하고 서서히 가열하여 온도를 올려 주다가 450℃에서 30분 동안 유지시키면서 불순물을 제거한다. 다시 온도를 올려 600℃에서 30분 동안 유지시키면서 잔류불순물을 제거하고 다시 800℃로하여 30분 동안 가열 숙성시킨 후 냉각하여 정제된 소금을 얻는다.300 kg of natural salt is added to the furnace and heated slowly to raise the temperature, and then it is kept at 450 ° C. for 30 minutes to remove impurities. The temperature is again raised and maintained at 600 ° C. for 30 minutes to remove residual impurities, then heated to 800 ° C. for 30 minutes, and then cooled to obtain purified salt.
[실시예 2]Example 2
해수염 500kg을 노에 투입하고 서서히 온도를 상승시켜 주다가 500℃에서 1시간 동안 유지시키면서 불순물을 제거한다. 다시 온도를 올려 650℃에서 1시간 동안 잔류 불순물을 제거한 다음 650℃에서 1시간 동안 숙성시켜 냉각후 정제된 소금을 얻는다.500 kg of sea salt is added to the furnace, and the temperature is gradually raised, followed by removal of impurities while maintaining at 500 ° C. for 1 hour. After raising the temperature again to remove residual impurities for 1 hour at 650 ℃ and then aged for 1 hour at 650 ℃ to obtain a purified salt after cooling.
