Description

{Salt production method using mesh}

And a method of using the net to deposit sun-salt

 Salt is also called sodium chloride and is sodium chloride (NaCl)

Examples of sources of salt include rock salt, salt water, underground water, and seawater.

Two thirds of the world's salt production comes from rock salt.

 Salt can be classified into sun salt, rock salt, mechanical salt, remedial salt, and processed salt.

Solar salt (sea salt) is a salt in which the salt dissolved in seawater is converted into a saturated function by solar heat, wind force, and natural forces.

 These salts can be roughly divided into three areas depending on specific production methods, in areas where evaporation of water is less, that is, in areas or periods where the amount of evaporation is more than three times of precipitation.

 Areas with large landscapes and low rainfall, such as Australia or Mexico

 Areas that are trapped on land and have a large amount of water that evaporates rather than the amount of incoming water

Areas with more distinctive four seasons, such as Europe (France, Portugal, Italy, Slovenia), Asia (Vietnam, China, India, South Korea)

 Looking at each of these representative salt production methods,

With multi-evaporation solar salt,

Salt production methods in areas where the four seasons are distinct, such as Europe (France, Portugal, Italy, Slovenia), Asia (Vietnam, China, Korea etc.) and where evaporation is more than rainfall for several months during the summer, Unlike salt in Australia and Mexico, the sea water is concentrated through several stages of evaporation to increase the efficiency of evaporation.

 These countries mainly produce salt mainly in the sunny summer season, and the more stages of evaporation land, the more manual work is needed, but the higher the crystal formation efficiency.

Therefore, Korea has the highest efficiency per unit area with the highest number of evaporation stages except reservoir and crystal ground.

 Our sun-salt phase is typically run through 6 to 10 evaporation stages,

This evaporation paper is divided into two stages: the first evaporator is to raise the seawater having a water concentration of 2.5 to 3% to 8%

 The second evaporator can be said to raise the concentration of the water to about 15%.

It takes about two weeks to raise the seawater to 20% water concentration, which is very weather-affected.

 Although there is a difference by region, it is closed in the winter frost season. In early spring, decontamination preparation work is performed. In the hot season, decontamination work is performed.

 And because sunny salt is produced only on a clear day, and it can not be produced on a rainy day, it is a salt famine when the drought is severe, and a salt famine when the rainy season is long,

As for the weather statistics, it is common to produce 63% of annual production in April, June and June, and 37% in 7, 8, 9 and October.

 Conventional torsion Of the solution  In the prior art of prior art and floor materials,

Prior Art 1 discloses a plastic sheet member for covering a salt-containing top plate and a method for coating a salt-containing top plate using the same, and a method for coating a salt-

Prior Art No. 2 discloses a method in which a curing hardener is mixed with a mortar mixed with tidal flats, briquettes, fine sand, and cement, and a casting mold is installed in a fiberglass mesh net with a reinforcing net, Method is being provided.

 In addition, the technology that uses the most commonly used tidal flats on the floor of the tidal flats has been introduced in Japan in 1907 in the Juan region of Gyeonggi Province, Korea. Since then, the salt floor material has been used as a tidal flat floor, Gold flake, ceramic tile, PVC monolith.

 The production method of PVC monoliths has been popular due to the excellent whiteness of the sun-dried salt and increased production,

Nowadays, PVC monoliths are contaminated with environmental hormones such as sunflower crystals precipitated from PVC monoliths due to the plasticizers contained in the PVC sheets, and these pollutants are introduced into the salt tidal flats and seawater. It is in a state of returning to the preference for tofan salt produced at the bottom of the tidal flat soil again.

 However, compared to the sun salt produced on the salt floor of PVC monolith, the sun salt produced on the bottom of the tidal flat contains much more minerals and useful organic chemicals. However, , The influx of foreign matter and the decrease of the production, the local salt producers are reluctant to produce tofan salt.

Salt crystals are formed by solar heat and wind.

Therefore, the quality of salt varies according to the monthly temperature it produces.

The reason why Korea does not produce high-quality salt even though it has a tidal-flat environment as its base is because it does not have the technology to produce salt suitable for monthly temperature.

 The production period of high quality raw salt suitable for edible salt is from May to September, which is more than 15 degrees Celsius, and salt produced and produced in this period is salt.

 To produce good salt,

Generally, it is supplied to each decision paper through the water channel by pouring the saturated function concentrated in the salt water of the crystal paper,

 The function is evaporated by the solar wind and the wind, and when the salt crystals are determined, it becomes a structure that replenishes the saturation function in the salt water.

The saturated function is supplemented once, and when it is coated on the second day, two days salt,

2 times a day to supplement and 3 days after the day when salt,

Three times a day supplementation, the day after the fourth day is called salt and salt.

 As a way of producing sea salt in the sea water until now

1. How to use tidal flats in salt marshes

2. How to use tiles on the bottom of a tidal flat in a salt mine

3. There is a method of using pp platelets on the tidal flat floor

 A lot of research

1. The method of using the tidal flats in the tidal flats is only 1/6 of the method of using the flaked flounder because the amount of the sun-salt bodily fluids is very low and there is a problem in productivity

And the risk of deterioration of the quality of the sea salt caused by contamination of the tidal flat

2. The method of using the tiles on the bottom of the tidal flats in the salt marsh is only one-third of the method of using the mushrooms in comparison with the investment cost, which is problematic in low productivity and excessive investment cost

3. In the tidal flat, the method of using the pp platelets on the bottom of the tidal flats is highly productive, but is exposed to the risks of the chemicals of the plastic platens.

Step 1, a step of forming a mat with a stainless steel net

When the amount of salt to be determined is 3 kg, the load imposed on the stainless steel teat due to the weight of the sun dried salt is not large. Therefore,

 It is more dense and convex than plain weave, which is produced by crossing 1: 1 of longitudinal and transverse lines based on 10m width and 10m length, Air is passed through a twilled Dutch weave net,

 As a black paint material, Magni 234 is a black coating method for commonly used stainless steel and aluminum-treated stainless steel,

 A black stainless steel mesh is used which is formed by applying coil-coat, flow-coat or spray method on cleanly dried stainless steel.

The size of the unit field of the deciduous ground is arbitrarily set to 10 m in width and 10 m in length,

Stainless steel net 6 meshes cut in width 2M X 11M width 2M length 90M were superimposed on the edge and fixed to the horizontal auxiliary bar and vertical auxiliary bar by welding or the like,

A black stainless steel tape is formed by fixing the mesh and the auxiliary bar inside the rectangular frame formed of the stainless steel bar and the net

1. A process for producing a rectangular frame using a stainless steel square pipe,

2. Adhesion of a stainless steel mesh of 8 mesh mesh to a metal mold,

3. Four stainless steel bars on the edge of a rectangular stainless steel net The four vertical bars on the edge of the harvester are attached to the vertical strut which is attached to the vertical strut and can be moved up and down.

In the second step, Compaction process ,

It is composed of reservoir, evaporation paper (first evaporation paper, second evaporation paper)

A seawater reservoir storage step for storing the seawater in the reservoir by using a water pump for the seawater or opening the seawater of the seawater at the high water level to remove the impurities,

A preliminary evaporation step of pumping the seawater settling the pollutants of the seawater in the reservoir to the first evaporation paper and continuously evaporating water in the seawater continuously following the natural evaporation and tillage process,

The evaporation step of pre-evaporating the seawater to evaporate the seawater in the second evaporation paper and the evaporation paper of the multi-stage by sunlight and wind over a certain period of time, thereby making the saturation function of the salt concentration 2026%

After the crystal paper in which the salt is determined is cleaned with water,

In the case of summer, the salt crystals are crystallized by the solar heat and wind in the summer to provide a saturation function, which is obtained by concentrating the saturation function of the salt concentration 2026%

When the saturation function of the tidal wave is 27, it forms a thin salt film on the surface of the saturation function. When the salt which is not submerged and floats in the first place is determined,

 In addition, the salt that is not exposed to the open salt is gathered by the sunlight and the wind, and the salt crystals are getting heavy, and the salt crystals settled on the net of the bottom of the crystal are stuck to form the coarse salt crystals on the net

At this time, the salt crystals formed on the net are lifted from the stainless mesh net,

A first trash removal step of removing the first trash by leaving the contaminated sun salt in the net for 24 hours with the trash removal step,

It is not a method of flushing a salt floor with a large shovel, which is a general flushing method, but it is placed on a stainless steel net and left until the next flushing, It is possible to reduce the labor cost by collecting the sun-salt crystals from which the first trunk has been removed by brushing off the net

The method of the present invention comprises the steps of transporting salted salt obtained from the primary wastewater removal step to a storage warehouse for 4 weeks to 10 weeks,

At the high tide, the sea salt is sent to the evaporation ground from the sea water to the evaporation ground and dried by the solar heat and the wind. When the salinity is about 20 ~ 25%, it is sent to the decision ground and the salt crystals which are determined are raked and collected. Packaged and produced.

 However, the sea salt produced by the conventional method contains not only various kinds of impurities such as seawater and tidal flats but also a harmful component to the human body is extracted into the wastewater.

 Since most conventional processes are manpowered by the conventional methods, it is expensive compared with natural salt such as imported salt or salt, which is produced in a country that has low wage labor,

In this way, a considerable number of domestic sun-salt producing companies that produce sun-salt are suffering from difficulties.

 In the present invention, the method of capturing the sun-salt is performed by using a black-coated stainless steel net, which is not a base plate, on the bottom of the trough, and the seawater is evaporated while being immersed on the bottom of the trough. If the net is lifted, the salt water will fall into itself and the salt will be harvested immediately. If the net is lifted for a certain time, the wastewater will fall off well and dry naturally, so that it can be coated with high quality sodium chloride.

  Prior to the step of depositing the salt crystals, the salt crystals formed in the salt water are first subjected to a high-quality salt called "salt"

 Another advantage is that if you dip the net into salt water and wait for the salt crystals, you will be able to secondarily fill the salt.

 In addition, since it is naturally produced in a natural state without any artificial post-processing, it does not burden the tidal flats, thereby avoiding the eutrophication of the tidal flats and the fear of contamination of the plasticizer due to the use of the pvc plate,

 In order to increase the production rate freely by increasing the removal rate by repeatedly performing the step of high-quality mannitol and the mannitol of low-cost mannitol,

 The net type netting made of stainless steel net can produce high quality sun salt, so it is advantageous to reduce the labor cost of the best salt which is good for use as natural natural salt for cooking.

Characteristics of Tidal Flat

 The sea receives numerous organic and inorganic materials, and these inorganic and organic materials are used repeatedly by the living ecosystem as nutrients and neutralizing toxic substances. There is a tidal flat at the center of this vitality. Tide and ebb occur twice a day.

 The phenomenon of tide and ebb tide acts to mix the components of seawater constantly.

 It is considered that the difference in the composition of the salt is due to the difference of the manufacturing method although there is no big difference in the composition of the sea water. Among them, the influence of the decision paper greatly influences.

In other words, the production of the sun salt is the same as that of collecting the salt remaining after removing the moisture in the seawater by the heat of the sun and the wind, but determining the content of the minerals in the salt particle depends on the crystal formation method in the crystal paper.

 In both the world famous sun salt and our sun salt, the crystal formation of salt occurs at about 25% of salinity, and the shape of the reservoir or multi-stage evaporation paper is the same even though there are differences in size and number of steps, It is the difference of whether the sun salt is produced on the tidal flat or whether it is produced on the floor material such as black plate, tile, Onggi.

 The difference in the bottom of the decision ground is not only easy to work but also noticeable difference in solar heat.

The use of a flooring material having such a high thermal efficiency has an effect that the water (brine) temperature rises and the water evaporates quickly, resulting in the formation of crystals quickly.

In fact, tidal flat solar rays require a crystal formation period of 4 days to 15 days,

When the bottom of the crystal paper is a black plate, a crystal formation period of 1 to 2 days is required.

The reason why the crystallization method of salt crystals is different is that it is a process of crystallizing the salt dissolved in seawater by evaporating water depending on the natural power such as solar heat and wind force, Should be used to promote water evaporation and prevent water leakage and dilution by external water.

 As can be seen from the above description and Table 1

The rate of removal is determined in the order of the highest removal rate and the Onggi tile toppan tidal flat

 In the present invention, the bottom of the crystal paper is not made of a conventional top plate,

Keeping the tidal flat floor,

1. A black stainless steel net coated with black paint was prepared in the form of a netted net according to the size of the ground of the deciduous ground,

2. When the flour is settled down in saturated salt water and placed on the bottom of the tidal flats

3. When the crystals of the stannous salt are formed on the stainless steel pot

4. When the stainless steel tray is lifted out of the brine by the means such as a doline along the supporting column formed in the trough of the salt field,

 In the first step, stainless  Process of forming a teabag with net

When the amount of salt to be determined is 3 kg, the load acting on the stainless steel vat due to the weight of the sun salt is not large,

 In order to maintain the shape of the tray rather than the rigidity of the tray, four bars of the horizontal bar and four bars of the vertical bar were placed on the bottom of the bottom of the tray, Four pairs of horizontal and four pairs of bars are welded to form a container frame. One of the four container tabs of the container is opened and closed by means of a hinge to collect the determined salt It is desirable to open the jaws on one side and make the jar to collect the salt.

 Determining the Size of Stainless Steel Tissue As the size of the tilling field may vary depending on the situation of the tortoise, it is set arbitrarily with the size as 10 m and 10 m,

It is preferable that the number of the auxiliary bars, the size of the bar, and the size of the net are differently applied according to the size of the field

 As for the method of selecting the net, it is preferable to use plain weave in which the cross line is 1: 1,

It is preferable to use a twilled Dutch Weave mesh of 8 mesh which is dense and has a high density and is well permeable to liquid and air,

 Magni 234 was selected as a coating material which is a material for black coloring,

Magni 234 is a black corrosion-resistant coating for stainless steel and aluminum-treated stainless steel,

 The coating method can be applied to a cleanly dried substrate and cured in an oven,

Stainless steel can be coated by a coil coat method,

A black coating having a heat resistance of 450 Celsius can be made.

The coating to be applied to the stainless steel net according to the present invention is a black stainless steel obtained by coating a black color paint on a stainless steel net by a coil-coat, flow-coat or spray method, It is desirable to use a network.

< Example  1>

1. The size of the unit field of the decision ground is arbitrarily set as 10m in width and 10m in length,

A stainless steel square pipe was used to form the bottom of the vat with the side bar 3 and the vertical bar 4, and a 10 m vertical bar and a 50 cm vertical bar and a 50 cm vertical bar 5 were fixed by welding means, A step of forming a metal mold 1 to form a rectangular mold in which the four jaws 6 are formed,

One of the four engaging jaws is fixed to the engaging member with a hinge and is assembled to be openable and closable.

2. Using a stainless steel net with a width of 2M and a length of 90M, 6 meshes cut with a width of 2M X 11M were overlaid on the edge by 20cm, Securing a stainless steel net 2, i.e., a mesh, of 8 mesh by welding means to the metal mold,

3. The formation of the jaw jaw is made by attaching to the bar which forms the jaw of the jaw,

4. The four vertical bars formed at the edges of the teabag and teat jaws (6) with the square stainless steel net (2) formed in the form of a net are attached to the vertically movable rail (7) (E) comprising a step of forming a sachet (E) with a stainless mesh fabricated to be moved up and down along a rail groove (8) attached to the saddle (D) by a moving means such as a pulley (9) A process for forming a teabag with a stainless steel net.

 The countries with the highest efficiency per unit area of production in the world are Australia, followed by Mexico, Korea and China.

 In other words, the amount of evaporation is the biggest variable and rainfall is the next variable. Korea is much more efficient than China because it uses much more rainfall than Korea but it is relatively small in Korea and it uses solar energy to collect and store rainfall function. There is a difference that they often harvest.

As shown in Table 2, the content of minerals except for sodium was high, and the contents of potassium and magnesium were three times higher than those of other imported ones, and the amounts of calcium and potassium , And magnesium content was very low.

 As a result of testing the general items of foreign salt and total ammonium salt in Jeonnam, the content of sodium chloride in Jeonnam was lower than that of Jeonnam, but the content of water and sulfate was higher than that of Jeonnam. I was born,

Sodium chloride was the most common in Australia and Mexico.

It is believed that the formation of these fast salt crystals, which are frequently harvested in a short period of time by increasing the thermal efficiency by using a black plate in the determination paper, shows a difference in the constituents, and thus contains a lot of minerals in the salt particles.

 The conclusions from the above comparison are

According to the material of the tidal flat bottom layer, the tidal flats produced in the tidal flats are classified into toppan salt, long plate flour, and tile flour.

 According to reports from France related academic circles, it is known that the high content of mineral in the crystallization deposits on the bottom of the tidal flat is due to the influence of the microorganisms in the tidal flats on the salt crystals.

Salt, which is rich in minerals, ananoic acids, organic compounds, etc., contains salt produced from toppan (tidal flats) and contains a strong salty sodium chloride, which gives a unique flavor and softness and sweetness. It works.

 Relatively, it is easy to work because the salt floor is laid out with a plate or tile, but various ingredients in the tidal flat are difficult to permeate into salt, so the nutrients are relatively low. In case of the long plate salt, there is a problem that when the long plate corrosion occurs, harmful components generated in the plate can be contained in the salt.

In addition, bottom tidal flats can not communicate with the outside air, resulting in the death of mature life forms and decay of mites

 Because of the high content of minerals produced in the plate,

It is very slippery when I touch the function of the summer warp decision paper.

This is due to the glycerol content that many hawthornic microbes in the tortoises have produced to withstand high osmotic pressures.

 An organism generally increases the amount of a substance with a low molecular weight in the cell to withstand high osmotic pressures. It has been reported that the determination function slips because the microbial cells produce glycerol with a small molecular weight.

It is also reported that the microorganisms that have taken all the measures to withstand such high osmotic pressure can not survive if the salinity of the crystal paper exceeds 40%, and the mineral content is increased because the minerals in the cells, which are inorganic salts,

 In the present invention stainless  The black coating of the net,

By absorbing the heat of the sun and increasing the temperature of the saturation function, the crystals of the salt are formed quickly.

 Instead of simply using black color, it absorbs sunlight to generate heat, so it has superior heat absorption and radiant heat compared to tidal flat floor.

 In other words, the principle that an object radiates radiant heat is that the heat energy that is contained inside is gradually transferred to the surface, and the most located particles emit the heat energy transferred in the form of electromagnetic waves.

 At this time, the electromagnetic waves emitted by the unit particles are determined according to the temperature and other characteristics of the object.

Therefore, a coarse mesh has a larger number of outermost particles than a smooth surface,

As the amount of radiant heat per unit time increases, the trapped water in the deciduous ground can accelerate the salt crystals by the radiant heat of the black coated stainless steel net.

The black coating of the present invention stainless  Network The method of compaction  We get mineral-rich salt crystals,

 Even though the black veneer is not the only one, the radiant heat of the black coated stainless steel mesh is almost the same as the black vinyl veneer in summer sunlight

 In addition, the nutrients in the tidal flats between the stainless steel meshes can be transferred to the forming salt crystals to provide a nutritious salt,

The black coated stainless steel net on the tidal flats proved that sunlight absorption heat and radiant heat were generated, promoting the formation of crystals of salt, and that the salt flowers flow faster than the bottom of the tidal flat.

 In other words, when the temperature of the salt water is 27, the salt flower begins to bloom. The black coated stainless steel mesh absorbs the heat of the sun to rapidly raise the temperature of the water. In case of tidal flat using conventional tidal flats or tiles, The black-coated stainless steel mesh of the present invention starts to bloom from 1 to 2 days, so that the salt flowers are formed 2-3 days earlier than the tidal flats or tiles.

In addition, labor costs and costs are reduced, for example, in the tidal-flat floor, due to the delay in the corruption of the tidal flats through the air and the shifting of muddy soil.

When the saturating function of the torsion is received by the sunlight, a thin salt film is formed on the surface of the saturating function. When the salt, which is not settled first and is floating, is determined, it lifts the tumbler (E) step,

 In addition, the salt that is not coated with the dried salt is gathered by the sunlight and the wind, and the salt crystals are getting heavier and heavy, and the salt crystals are attached to the bottom of the deciduous ground and the coarse salt crystals stick to the stainless steel net (2).
