The present invention relates to a method for producing granular mineral salt, and more particularly, to a method for preparing granular mineral salt in which the natural salt is granulated and micronized without damaging the mineral contained in the natural salt.

In general, salt is absorbed by the human body to control the osmotic pressure of the body fluids, stimulate the nerves involved in the equilibrium of acid and base, as well as constituents of digestive fluids, as well as seasonings to adjust the taste of food.

In other words, salt is involved in body functions such as voltage regulation of cell membranes and blood pressure in the body. Especially, sodium ions play an important role in osmotic pressure of body fluids, plasma volume maintenance, nerve excitement, muscle contraction and nutrient movement. Ingestion should be careful because it causes high blood pressure.

These salts are made mainly from seawater, which contains minerals such as potassium, calcium, magnesium, zinc, iron, phosphorus, sodium, and manganese, which are useful to the human body, while magnesium chloride and calcium chloride, which are harmful to the human body, And magnesium sulfate.

Such salts include, for example, salts of salt (also known as 'white salt' or 'flower salt'), salts of salt (mechanical salts coated with sodium glutamate or complex chemical seasoning), washing salts, by-product salts (recovering salts), imported salts (rock salts), etc. Likewise, it is processed for a variety of purposes, from household salts to factory salts.

However, these processed salts are made from seawater containing a large number of minerals that are beneficial to the human body because they are transformed into molecular structures and sizes that are not suitable for absorption in the body even if minerals are lost or remain in the process as described below. Natural mineral supplementation through salt becomes difficult, which leads to the phenomenon of mineral deficiency despite the many usefulness of salt (mineral deficiency here, except for artificial mineral supplementation).

At this time, the mineral is an important substance used as an enzyme material involved in metabolism in the body, no matter how small the required amount, if it is not spread it will not be able to make enzymes, eventually metabolism becomes difficult to maintain health It becomes impossible.

Therefore, there is an urgent need for a new type of salt that can relieve mineral deficiency naturally by allowing the absorption of minerals through the intake of salt alone.

The present invention was created in order to actively respond to the request as described above, while containing a large number of minerals contained in seawater and mud flats in natural salt without modification, but finely granulated the particle size up to 7㎛ through agitation and granulation The main purpose is to provide a granular mineral salt manufacturing method that can be used as a seasoning as well as health food.

The present invention, in order to achieve the above technical problem, to create a reservoir of a certain size in the tidal flat and to store the seawater by inflowing and then to evaporate naturally to adjust the salinity to 20%, while changing the storage tank for a long time in the storage tank Seawater concentration and filtration step to induce sedimentation and at the same time to move the filtration through a filter of non-woven material to concentrate up to 25% salinity; Stirring the concentrated 25% seawater with a nanofresh unit to reduce the particle size of NaCl and evenly disperse it; In the mineral salt manufacturing method comprising a hot spray drying step of producing a mineral salt by hot spray drying on a rotating disk of the concentrated seawater passed through the stirring step; A granulation step of mixing the mineral salt produced through the high temperature spray drying step at a ratio of 9 to 10% by weight with respect to the total weight of the mineral salt to make a slurry, and extruding it to granulate; It provides a granular mineral salt manufacturing method further comprising a drying step of drying the granulated mineral salt through a granulation step for 1 to 2 hours under a temperature atmosphere of 80 ~ 120 ℃.

At this time, the particle size of the mineral salt to be granulated in the granulation step is characterized in that the 0.8 ~ 2.0mm.

Here, the seawater used as a raw material is also characterized in that the seawater directly evaporated in the salt field as described.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

1 is a flow chart showing a granular mineral salt manufacturing method according to the present invention, Figure 2 is an exemplary view showing a high-temperature spraying process of producing the granular mineral salt according to the present invention.

First, in the granular mineral salt manufacturing method according to the present invention, after stirring the sun salt having a particle size of about 5mm and dried by high temperature spraying method, it is powdered to a particle size of 7㎛ and then granulated to reduce the loss of minerals. It is to be minimized.

To this end, the granular mineral salt manufacturing method according to the present invention, as shown in Figure 1, seawater concentration step (S100), filtration step (S200), stirring step (S300), spray drying step (S400), granulation Step S500, drying step S600, and packing step S700 are performed in this order.

At this time, the packing step (S700) is optional, it is not necessarily included in the scope of the present invention.

Then, the granular mineral salt manufacturing method according to the present invention will be described in more detail in light of the above-described steps.

In order to prepare the granular mineral salt according to the present invention, first, the seawater concentration step (S100) is performed.

The seawater concentration step (S100) is to concentrate the salinity of conventional seawater up to 25%, for example, to create a reservoir of a certain size on the tidal flat, and to create a waterway so that the water can be introduced into the reservoir is repeated every 15 days Open the door that closed the waterway at high tide and store some of the seawater inflow into the reservoir and store the stored seawater to set the salinity to 2 ~ 3% by natural evaporation to settle the insoluble content to some extent. To do that.

Then, when the salinity of the stored seawater reaches 2 ~ 3%, some of the insoluble content is introduced into the saltwater in the tidal flat, and the salinity is continuously adjusted until the salinity reaches 20%, and then the salinity is 20%. When it reaches the storage tank, it saves 20% of the stored salinity and concentrates it to 25% to produce the saturated function.

At this time, the process of adjusting the salinity to 20% is formed by forming the inclined salt over about 1km, and by discharging the salt plate to circulate, but by the natural evaporation using the sun and wind by appropriately adjusting the circulating flow rate It is desirable to make it.

This is because by using the natural evaporation on the tidal flat to use the solar energy, natural energy, because it can reduce the fuel cost and naturally increase the mineral content.

The reason for controlling the salinity of the seawater to 25% is that the maximum concentration of salt can be saturated in water is about 25%, and when it is 25% or more, crystals are generated in a supersaturated state. It is preferable to naturally concentrate to this extent because problems are caused.

In addition, by changing the storage tank to make the seawater concentration step (S100) more smoothly, by maintaining the seawater for a long period of time, preferably 1 month, it is possible to naturally improve the salinity, and at the same time induce continuous precipitation of insoluble content At this time, the filtration step (S200) is performed.

That is, the filtration step (S200) is to remove impurities contained in the seawater as much as possible by filtering using a filter of non-woven material when moving the seawater to another storage tank.

In this way, when the salinity of the seawater reaches 25% by stirring it to perform a stirring step (S300) to reduce the particle size of the salt dissolved with water molecules in the seawater and induce even dispersion.

The stirring step (S300) by using a nano fresh unit (Nano Fresh Unit) or a known stirrer for about 3 hours to promote the mixing of seawater and air to further reduce the particle size of salt dissolved in the seawater, This leads to even dispersion and changes the state of sodium and chlorine ions.

Herein, the nanofresh unit is the same as a conventional stirrer having a structure of an accommodating portion which can easily accommodate a negative tron catalyst body, and it is not necessary to use such a stirrer, but to a well known stirrer. Of course, the negative ion catalyst body may be added while stirring.

In addition, the negative electron catalyst is a kind of negative electron catalyst and is known as a material that permanently generates electromagnetic waves of about 4 to 14 microns, and examples thereof include tourmaline.

In general, electromagnetic waves in the wavelength range of 4 to 14 microns are most easily absorbed by living organisms, and are called so-called "growth rays" because they act physically and synthetically in living organisms. As a result, it is one of the basic substances that play an important role in nature, such as activating cells of plants and plants, synthesizing proteins, and purifying contaminated water.

Furthermore, growing rays have been confirmed to have the strongest energy for weak energy that has a good effect on the cells of objects, animals and plants.

On the other hand, water does not normally exist in water molecules (H ₂ O) alone, and in fact, because they exist in a lump state like grape clusters, this is called a cluster of water (Cluster).

Generally, water is present in 36 ~ 37 clusters. Contaminated water is composed of 200 ~ 300, and more than 1000 in case of severely decayed wastewater, but 50,000 ~ 120,000㏄ / ℓ anion generated in nanofresh The growing energy of weak 4 ~ 14 microns of electromagnetic wave vibrates the molecules of water strongly to create vibration state, and changes the angle of water molecules from 104.5 ° to 95 ° or 180 ° to form 5 ~ 6 small clusters. To make magnetized negative ionized water.

At this time, when there are six clusters is often referred to as "hexagon", which appears a lot around 5 ℃ Celsius.

As such, it is possible to change NaCl into a structure captured by Na ⁺ and Cl ^- in a small hexagonal form cluster by the effect of even dispersion by agitation with a nanofresh unit (a tourmaline) or a known tourmaline. do.

Through this process, 25% of the salt water in which sodium ions and chlorine ions are captured in hexagonal water is subjected to a high temperature spray drying step (S400).

The high temperature spray drying step (S400) may be performed, for example, in the form as shown in FIG.

That is, as shown in Figure 2, the shaft 14 is drawn from the top inside the sealed chamber 10 maintained at approximately 180 ~ 300 ℃, the disk 16 is fixed to the end of the shaft 14, The shaft 14 may be rotatably installed by a driving means, and may be performed through a dryer facility having a configuration in which a supply nozzle 12 is connected to an upper end side of the chamber 10.

The high temperature spray drying process using this equipment is supplied to the chamber 10 preheated to about 180 ~ 300 ℃ in the form of spraying seawater into the chamber 10 through the supply nozzle 12, at the same time high speed, such as As it collides with the disk 16 rotating at high speed at a speed of 10000 to 15000 rpm, it is crystallized at the same time as drying.

Here, in order to dry smoothly, the disk 16 should have a rotation speed of at least 10000 r.p.m, and if it exceeds 15000 r.p.m, it is preferable that the disk 16 be rotated within this range because it imposes a burden on the equipment.

At this time, the seawater supply temperature may vary depending on the concentration of the seawater, so that the higher the concentration of seawater, the lower the supply temperature, and the lower the concentration, the higher the supply temperature.

When the high temperature spray drying step (S400) as described above can be produced a mineral salt with a particle size close to 7㎛.

In addition, the reason for limiting the internal temperature of the chamber 10 during drying as described above is difficult to maintain alkalinity when it is about 180 ° C. or lower, and when it exceeds 300 ° C., the alkalinity becomes strong, and thus it is preferable to limit the temperature to the above temperature range. Preferably it is most suitable for weak alkali when it is about 250 degreeC.

In this way, when the mineral salt of the fine particle size is produced, a step (S500) of granulating the mineral salt using a granulator is performed.

The granulation step (S500) is kneaded by adding water to make a slurry state, and the mineral salt of the slurry state is extruded to granulate. For example, the granule step (S500) may be in the form of allowing the slurry to pass through the screen (network).

Here, the amount of water added during kneading is preferably kneaded by adding 9 to 10% by weight relative to the total weight of the completely dried salt.

At this time, when the water content exceeds 10%, it is difficult to maintain the shape of the granules, and when the water content is 9% or less, the above range is suitable because the product remains in the powder state.

Through this process, the granular salt is completed, and the drying step (S600) is performed to finally manufacture and complete the granular mineral salt.

At this time, the drying temperature of the granulated salt is preferably 80 ~ 120 ℃, the drying time is suitable 1 ~ 2 hours.

In addition, the particle size of the granules is preferably 0.8 ~ 2.0mm (usually the size of the particle size of the granulator) to increase the utilization as needed.

In general, the optimum particle size, which is easy to produce and manage, is 1.2 mm, but it is particularly preferable in view of the use change to have the size of the above category which may include the same.

After that, if necessary through the packaging step (S700) will be shipped.

As a result of analyzing the composition of the granular mineral salt prepared by the method described above by EDAX (Mineral Component Analyzer), it was confirmed that the component content shown in Table 1 was included.

Na Mg Si P S Cl K Ca I Ba 29.82 3.52 0.17 0.18 2.16 58.64 0.66 0.30 0.16 0.45 Cr Mn Fe Ni Cu Zn Se Br Sr Sum 0.19 0.23 0.24 0.18 0.46 0.19 0.40 0.53 1.52 100

Wherein the component content is weight percent

As shown in Table 1, it was confirmed that the granular mineral salt according to the present invention contains a large amount of minerals without breaking or modifying various kinds of minerals, unlike general mill salt, mechanical salt, and roasted salts.

As described in detail above, according to the present invention, various kinds of minerals contained in seawater and tidal-flat can be contained in salt without modification, so that the mineral deficiency problem is naturally absorbed by the human body only by intake of salt. It has the effect of eliminating.
