Description

  The present invention relates to a method and apparatus for producing a mineral component-containing saline solution. In more detail, the manufacturing method of the mineral component containing salt solution for seasonings, cosmetics, and drinks which removed the heavy metal and impurities with the filtration apparatus using tourmaline (tourmaline), and raised the essential mineral component for the human body. And a manufacturing apparatus.

  Sun salt is made by drawing seawater into salt fields and evaporating water using wind and sunlight. Natural salt is nutritionally superior because it contains abundant minerals derived from seawater, especially calcium, potassium, magnesium, etc. essential for the human body and also contains organic components of tidal flats. Magnesium promotes cell metabolism, activates enzymes, and acts on bone metabolism together with calcium and phosphorus. Calcium strengthens cell membranes and bones and is involved in heart muscle and nerves. Potassium expels waste through the maintenance of water, regulates muscle contraction, and facilitates neurotransmission at the neuromuscular junction. On the other hand, refined salt that is widely used in general households is guaranteed hygiene because it has undergone a refining process, but sodium chloride accounts for about 95% of the ingredients, and other nutrient ingredients are close to zero.

  The annual production of sun salt in Korea is about 300,000 tons, which accounts for 43% of salt consumption in Korea. However, because sun salt is produced without going through a refining process, it was classified as a mineral by the 1963 Salt Management Act because it was unhygienic in Korea, and was not described in a food official book published in 1992. The Korean Food and Drug Administration has restricted the use of sun salt for preserving Chinese cabbage fish. For this reason, sun salt can be used when preparing kimchi or soy sauce at home or when pickling fish, but it cannot be used in industrial applications such as the manufacture of processed foods.

  In South Korea, therefore, sun salt producers and others insisted on the functionality and safety of sun salt, and made every effort to allow sun salt to be recognized as food. As a result, the Korean Food and Drug Safety Agency finally revised the salt management law after confirming the nutritional components and safety of solar salt from the research results and analysis results submitted by solar salt producers. And sun salt has been certified as a food, and since 2008, it has been described in the food officials.

  In the production process of sun salt, after salt salt is collected from a salt paddy, it is stored in a salt warehouse for a certain period of time in order to produce a salt with a good feel, and moisture containing bitter salt is removed. However, when the moisture containing such bitter salt is not sufficiently removed, there is a problem that the package becomes dirty due to moisture and the bitter taste remains in the salt. For this reason, in general, the salt is dehydrated by a centrifugal dehydrator, but there is a problem that various mineral components contained in the salt are also removed together with moisture.

  In order to retain the mineral component in the sun salt, a method of boiling seawater in the sun salt production process, a method of producing a salt having a high mineral content by spray drying, and the like are known. However, such a method is not easy because the apparatus becomes large. Moreover, in order to raise the mineral content of solar salt, the method of adding the mineral component from the outside and increasing the mineral content of solar salt is also utilized. However, a method for producing sun salt while retaining the natural mineral components of sun salt has not been studied much.

  Solar salt is unsanitary due to the characteristics of the manufacturing process, in which seawater is drawn into salt fields and water is evaporated using wind and sunlight, and a purification process to remove foreign substances from solar salt is necessary. is there. In addition, the reason why sun salt is certified as food is not because the problem of heavy metals contained in sun salt has been completely solved, but all natural products contain small amounts of heavy metals according to analytical techniques and materials. This is because the amount of heavy metals present in the salt is not at a level that is harmful to health.

  The salt standard (mg / kg) of the Korean Food and Drug Administration stipulates that arsenic is 0.5 or less, lead 2.0 or less, cadmium 0.5 or less, and mercury 0.1 or less. In addition, the Delaney clause that all foods should be free of carcinogenic substances in any amount, with the development of analytical techniques, carcinogens are now found in most natural products. Instead of the presence or absence of carcinogens, it was changed to the presence or absence of harmful levels of carcinogens.

  Solar salt includes heavy metals such as cadmium, mercury, lead, and arsenic, and various substances such as dioxins and ferrocyanide ions, which are components that cause endocrine disorders and carcinogenesis. The environmental hormone phthalate ester (DEHP: bis (2-ethylhexyl) phthalate) contains 15.7 times more sun salt (35.35 μg / kg) than purified salt (2.25 μg / kg). Purified salt is a method that removes only pure sodium chloride from sun salt, so it contains almost no heavy metals and environmental hormones.

  Solar salt contains many impurities other than those described above. Sand dust is a component of sand and is relatively high in salt fields located in sand lagoons, rock lagoons, tidal flats, etc. The total number of bacteria is not detected in purified salt, but in the case of sun salt, about 1,000 cfu per gram Sometimes a minute amount of bacteria is detected.

  Salt is an essential element for the human body, but salt is contaminated to a serious degree due to various factors such as the poor environment of salt fields that produce salt and the contamination of salt collected from lagoons with heavy metals and foreign substances. And is threatening our health.

  In other words, solar salt produced by evaporating seawater from solar water is contaminated with industrial wastewater contained in seawater, domestic sewage, agrochemical components flowing in from nearby fields, and heavy metals contained in Chinese yellow sand. Yes. It also contains harmful substances such as arsenic, lead, mercury, and cadmium that can cause terrible diseases such as cancer.

  Also, in the case of processed salt that is not solar salt, arsenic and lead are removed when high heat is applied to the salt, so a method of boiling or baking is used, but a large amount of dioxin is generated in this process. This dioxin is produced by the incomplete smoke glass process of chlorine compounds, and it is also a fatal carcinogen for the human body.

  In Korea, the potassium cyanide component was detected in rock salt imported from China and other countries, and it had a big impact, but it is still used for various food processing due to its low price.

  South Korea has no standard salt consumption due to its unique salted food culture, and daily intake of salt is much higher than the World Recommended Standard (WHO), so the dietary culture needs to be improved. At the same time, there is a need for salt that contains as little harmful substances as possible.

A second housing in which tourmalines are densely accommodated, a third housing connected to the second housing and containing a spherical tourmaline having a diameter of 5 to 10 mm, and the third housing And a fourth housing which is connected to the housing and in which spherical tourmalines having a diameter of 0.5 to 1 mm are densely accommodated.

  The mineral component-containing saline of the present invention is produced by the method for producing a mineral component-containing saline of the present invention.

  According to the present invention, suspended substances are removed in the first stage, heavy metals are removed in the second stage, the content of mineral components is increased in the third stage, and water molecules are removed in the fourth stage. By subdividing the clusters, it is possible to remove heavy metals and impurities from seawater, and to produce a large amount of saline containing a large amount of mineral components beneficial to the human body at low cost.

It is a flowchart which shows the manufacturing method of the mineral component containing salt solution of this invention. It is a top view which shows one Example of the manufacturing apparatus of the mineral component containing salt solution of this invention. It is a front view same as the above. It is a right side view same as the above. It is sectional drawing of a housing same as the above. It is a schematic diagram which shows operation | movement of a 1st housing same as the above. It is a schematic diagram which shows the mechanism of the heavy metal removal in the 2nd step of the manufacturing method of the mineral component containing salt solution of this invention.

  Hereinafter, the manufacturing method and manufacturing apparatus of the mineral component containing salt solution of this invention are demonstrated.

  The method for producing a mineral component-containing saline solution of the present invention includes four stages S1 to S4 shown in FIG. Correspondingly, the apparatus for producing a mineral component-containing saline solution of the present invention includes four housings 1 to 4 shown in FIGS. The housings 1 to 4 are made of metal such as aluminum or stainless steel, plastic, or the like, and contain a filter medium or tourmaline as will be described later.

  First, in the first stage S1, seawater having a salinity of 15 to 21 degrees is passed through the first housing 1 in which a filter medium made of chemical fibers is accommodated. The main purpose of this first stage is to remove suspended material.

  Here, as the seawater having a salinity of 15 to 21 degrees used as the raw water, for example, seawater immediately before the salt crystallizes out as the salt in the salt field can be suitably used. The salinity here refers to the degree of baume.

  The first housing 1 accommodates a filter medium 11 made of chemical fiber. As this filter medium, for example, a material obtained by heat-sealing a yarn made of polypropylene fiber is preferably used. A pipe 12 connected to the discharge port of the pump 5 is connected to the upper portion of the first housing 1, and a pipe 22 connected to the second housing 2 is connected. A drainage pipe 13 is connected to the lower portion of the first housing 1. The suction port of the pump 5 is connected to a pipe 51 connected to a seawater tank (not shown). Then, the seawater supplied from the pump 5 via the pipe 12 passes through the filter medium 11 in the first housing 1 and is sent to the second housing 2 via the pipe 22 after the suspended substances are removed. It is supposed to be.

  Moreover, the 1st housing 1 can be comprised by a vibration compression filtration apparatus as shown in FIG. The vibration compression filtration apparatus contains a large number of spherical filter media obtained by heat-welding a thread made of polypropylene fibers in a housing having a sealed structure, and the filter media is moved up and down to add the filter media. A piston for pressure is provided, a pipe for introducing raw seawater at the upper part, and a pipe for discharging backwash water while discharging filtered seawater at the lower part. As shown in FIG. 6, the operation of the vibration compression filter is as follows: (a-1) The piston descends and pressurization to the filter medium is started. (A-2) The pressure is increased when the piston reaches the lower limit point. The introduction of the raw seawater is started and the filtration process starts, and the filtration process is continued until the inlet pressure reaches a predetermined value. (A-3) When the inlet pressure reaches a predetermined value, the piston rises to release the pressurization by the piston and backwash water is introduced. (A-4) Backwash water when the piston reaches the upper limit point And air is introduced to enter the backwash process. Here, the filter medium is washed by ejecting backwash water and air from below the filter medium. Suspended substances attached to the filter medium are removed and the filter medium is regenerated by agitation and vibration in the backwashing process, and collision between the filter media. Then, the above operation is repeated again. Thus, by adopting the vibration compression filtration device, it is possible to easily regenerate the filter medium.

  In the first stage S1, 70 to 80% or more of impurities such as suspended substances and heavy metals contained in seawater are preferably removed.

  In the second stage S2, the seawater obtained in the first stage is passed through the second housing 2 in which a large number of cube-shaped tourmalines having sides of 80 to 100 mm are densely accommodated. The main purpose of this second stage is to remove heavy metals.

  Here, as tourmaline, iron tourmaline is particularly preferably used. The same applies to tourmaline in the third and fourth stages.

  The second housing 2 contains a large number of cubic tourmalines 21 each having a side of 80 to 100 mm. A pipe 22 connected to the first housing 1 and a pipe 32 connected to the third housing 3 are connected to the upper portion of the second housing 2. And the seawater supplied via the piping 22 passes between many tourmalines 21 in the 2nd housing 2, and after a heavy metal is removed, it is sent to the 3rd housing 3 via the piping 32. It is like that.

  In the second stage S2, 90 to 99% or more of impurities such as suspended substances and heavy metals contained in seawater are preferably removed together with the first stage S1.

Note that tourmaline has a hexagonal crystal structure and contains iron, magnesium, aluminum, etc., and is said to generate negative ions and far infrared rays. In addition, it is called tourmaline because it takes electricity when the crystal is heated. Tourmaline causes a discharge when it comes into contact with moisture, and generates a weak current of about 0.06 mA. At this time, water is electrolyzed, and hydrogen ions are combined with electrons attracted to tourmaline to be converted into hydrogen gas (H ₂ ) and released. Hydroxide ions are changed to hydroxyl ions (H ₃ O ₂ ⁻ ) by binding with surrounding water, and the action of the hydroxyl ions detoxifies heavy metals and removes impurities as shown in FIG. Conceivable.

  In the third stage S3, the third housing 3 in which the seawater obtained in the second stage contains a large number of spherical tourmalines having a diameter of 5 to 10 mm and is maintained at 30 to 36 ° C. Let the inside pass. The main purpose of this third stage is to increase the content of mineral components.

  A large number of spherical tourmalines having a diameter of 5 to 10 mm are densely accommodated in the third housing 3. A pipe 32 connected to the second housing 2 and a pipe 42 connected to the fourth housing 4 are connected to the upper portion of the third housing 3. And the seawater supplied via the piping 32 passes between many trimarine in the 3rd housing 3, and after the content of a mineral component increases, it passes into the 4th housing 4 via the piping 42. It is supposed to be sent.

  The third housing 3 is provided with a temperature control device having a temperature sensor and heating means (not shown), and the third housing 3 is maintained at 30 to 36 ° C. . Thereby, the tourmaline in the 3rd housing 3 is also maintained at 30-36 degreeC, and the property which takes electricity by the heating of tourmaline is promoted.

  In the third stage S3, mineral components such as magnesium, iron, boron, and silicon contained in tourmaline are eluted in seawater, and the mineral components in seawater increase. Moreover, the temperature of the seawater which passes the 3rd housing 3 reaches 20-25 degreeC.

  In the fourth stage, the seawater obtained in the third stage is passed through a fourth housing 4 in which a large number of spherical tourmalines having a diameter of 0.5 to 1 mm are accommodated. The main purpose of this fourth stage is to irradiate far-infrared rays emitted by trimarin.

  A large number of spherical tourmalines having a diameter of 0.5 to 1 mm are densely accommodated in the fourth housing 4. A pipe 42 is connected to the upper portion of the fourth housing 4 and a pipe 52 connected to the discharge port is connected. And the seawater supplied via the piping 42 passes between many tourmalines in the 4th housing 4, and after irradiating the far-infrared ray which a trimarin emits, toward the discharge port via the piping 52 It is supposed to be sent.

  In the fourth stage S4, when the seawater heated in the third stage S3 passes between a large number of spherical spherical tourmalines having a diameter of 0.5 to 1 mm, far-infrared rays are emitted from the tourmaline to the seawater. It is considered that the seawater cluster is subdivided by the irradiation.

  Moreover, the mineral content contained in tourmaline elutes, and finally, seawater having a salinity of 18 to 24 degrees with a salinity of about 3 degrees higher than the raw water is obtained.

  According to the present invention, a soft and delicious mineral component-containing saline with high cell permeability is obtained.

  Table 1 shows the results shown in Table 1 when seawater collected from the sea surface of Seogwang-gun, Jeollanam-do, South Korea was treated with the vibration compression filtration device shown in FIG. The removal rate of suspended solids (SS) was 93.57%.

  The final processed seawater was collected at the washing sun salt production plant in Shirakaba, Seiko-gun, Jeollanam-do, South Korea. And this seawater was processed with the manufacturing apparatus of the mineral component containing salt solution of invention. When the processed seawater was commissioned and analyzed by the Korea Food Research Institute, the results shown in Table 2 were obtained.

  A large amount of mineral components beneficial to health such as calcium 14.08 (mg / 100 g), potassium 745.57 (mg / 100 g), magnesium 2,742.90 (mg / 100 g) were contained.

  Table 3 shows the results of analysis of the pollution level of heavy metals in seawater in ponds where solar salt is produced in Korea. When these seawaters were processed by the manufacturing apparatus of the mineral component-containing saline solution of the invention, cadmium and lead were not detected.
