Abstract

PURPOSE: A method for making boiled salt using dried mud is provided to obtain brine having high salinity and containing natural minerals regardless of season and weather and to save labor force. CONSTITUTION: The method for increasing the salinity of brine comprises the steps of introducing dried mud into filtering cloth and dipping it into brine having the salinity increased through three-step natural evaporating zones of mud flat. Then, the brine having the increased salinity is supplied to two-step heating containers. A high-quality boiled salt is precipitated from a first heating container at a high temperature, while the additional amount of the brine is introduced and the temperature is decreased. In addition, the brine is heated again in a second heating container at a low temperature so as to remove impurities and to discharge the precipitates.

Description

Preparation and heating method of suicide using dried clay tidal soil

The present invention is a soil made by evaporating water by tilling soil of tidal-flat that does not enter seawater for 5-6 days when the salt is 10 ~ 12% hydride (Neap tide) It is used to elute various minerals contained in tidal flats by depositing it in the first and second stages.It also boils water containing minerals, and it is easy to remove impurities by adjusting the kiln's batch and controlling the temperature. It is to bring out the taste of salt salt.

Conventional salt manufacturing method is a salt-washing method of making salt after evaporating water step by step by solar heat by introducing salt water into salt field, refining processing of salt salt, method of depositing salt by boiling sea water directly, electrolysis of sea water And an ion exchange membrane purified salt to precipitate a salt (NaCl). In addition, there is suicide, which is the decontamination method of our ancestors, which makes salt water to penetrate seawater through dried mud flat soil, but production is stopped, and most of the domestic salt production is reprocessing of sun salt and sun salt. .

Among the decontamination methods listed above, reprocessing salts and purified salts except for salts and sun salts are not saline salts with a high NaCl concentration of 90-99% or more and a low content of various mineral components.

Tidal-flats contain various minerals (Ca. K. Ba. Mg, etc.) produced by the deposition of marine animal and plant carcasses (shell shells, etc.). This mineral is dissolved in the process of making clay and hydride, so it is crystallized like salt, so you can get a useful mineral when you consume suicide. In addition, low-salt suicides containing useful minerals increase the number of fermented microorganisms such as lactic acid bacteria in the process of making kimchi, and fermented saline. Enhance the taste of fermented foods by active metabolic activity.

On May 20, 2001, Taean Cultural Center in Chungnam held an event to reproduce the entire process of manufacturing traditional salt suicide, which had been cut in 50 years. Suflame, which was produced from the Three Kingdoms to the early 1950s, is the traditional salt of Korea. The manufacturing method of suicide produced by the west and south coastal tidal flats varies from region to region, but the principle is to dry the mud flat soil to make a clay and permeate seawater through the clay to increase the salinity in the cauldron. This salt is characterized by low salinity and contains more minerals than natural salts, since various minerals contained in tidal-flat are eluted when dissolved in seawater and dissolved in water, and are determined together with salt.

The following problems must be solved in order to make high-quality suicide with these characteristics.

Increasing the salinity of a function is very important. The salinity of seawater averages about 2.5%. When the seawater is filtered through the soil made for 6-7 days, the salinity of hydride is increased by 7-8%. This is the conclusion obtained in the process of producing traditional salt suicide, which was reproduced at the Taean Cultural Center in 2001-2002. The salinity of hydride and the yield of salt are closely related.

The key to making a clay in tidal-flats is the overcoming of natural conditions and how to replace manpower. Hamtos have to be produced on Nep tide twice a month (about 10 to 12 days) on high quality tidal flats, and it is difficult to produce stable water because it depends on season and weather. In addition, since tidal flats are infiltrated by seawater twice a day except for 6-7 days (twice a month), it is impossible to wash the soil using large machines. Eventually, manpower or the smallest cultivator must be used. To produce 1 ton of salt with a salinity of 7-8%, 200 tons of clay are required, and the manpower for making this is about 21 people.

How to adjust the heating temperature of the cooking pot depends on the taste and yield of suicide. The salinity of hydrate is precipitated at 26 to 30% of specific gravity, and the remaining amount of salt remains in the salt water (NaCl) which can be determined as salt. This salt (NaCl) contains a large amount of KCl MgCl ₂ MgSO ₄ , which has a bitter and astringent taste, and can be removed and removed from the brine to improve the quality and yield of suicide.

The present invention is to increase the salinity of the water and to elute the various minerals contained in the soil by immersing the soil in the water in a way to solve the problem as described above. In addition, sediment produced during the deposition of the soil is discharged in stages, and impurities are removed by adjusting the heating temperature of the heating cooker to make a high-quality salt rich in low salinity in a simple way.

First, FIG. 1 is an overall process diagram of the process of making suicide. To make suicide, the process of making clay (4) from the tidal flat and putting it in the filter cloth, making the seawater (15) by increasing the salinity of seawater using evaporation paper, and depositing the clay (4) in the water, It is divided into the process of boiling (15) to precipitate suicide.

2 is a step of making the clay 4. The condition of the tidal flat for the production of suicide is that the sand does not flow for about 6-7 days from 13 water, a little, 1 water, 2 water, 3 water, 4 water, 5 water, which is a little Neap tide. It should be mudflat mixed about%.

The structure of the tidal flats is tilled (1) with 13 small waters (large air planes), and the surface of the tidal flats does not dry out for a while. When the water on the tidal flat begins to break up, the soil block is crushed (2) and tilled (1). The soil (4) made by repeating the tillage (1) and crushing (2) operations (3) is introduced into the filter cloth (5) and transported to the brine reservoir (6) until the water in the tidal flat evaporates completely.

3 is a step of making the function 15. Neat tide is transferred to the primary evaporator (7) through the transfer pump (11) through the transfer pump (11) to the water reservoir (16) of the evaporator (7.8.9) made on the tidal flat. . The seawater of the primary evaporation basin (7) is moved to the secondary evaporation basin (8) and the tertiary evaporation basin (9) step by step for a while, and when the salinity ratio reaches 10 to 12% by evaporating moisture, the evaporation basin reservoir Gathered to (10), and then transferred to the water reservoir (16) using the water transfer pump (12).

4 is a step of depositing the clay 4 in the function 15. 1, the soil contained in the filter cloth (17) is deposited in the water function (15) transferred to the water storage (16), which increases the salinity of the water function (15) by 2-3%, increasing the yield of suicide. This is to make high-quality suicide by eluting minerals contained in the clay (4). The deposition method deposits more than 96 hours at the ratio of the amount of function 15 = clay (4) x 2. The immersed soil 4 is reduced to the tidal flat and the water 15 is sent to the second stage heating cooker 20 through the transfer valve (18). Sediment at the bottom of the water reservoir 16 is discharged through the discharge valve (19).

5 is a process of depositing the secondary clay soil 4 and the heating pot 20.24. The function 15 having the primary deposition 13 is transferred to the second stage cooking pot 20 and undergoes the secondary deposition process. The deposition ratio at this time is the amount of the function 15 = clay (4) x 5, and the deposition time is deposited until the temperature of the function 15 reaches 50 ° C. This is because impurities are suspended at the water 15 temperature of 50 ° C. After the deposition function 15 is transferred to the first stage cooking pot 24 through the transfer valve 22, the precipitate of the second stage cooking pot 20 is discharged through the discharge valve 21, and the water storage reservoir 16 Transfers the function (15) after primary deposition.

When heating the function 15 of the first stage cooker 24, the impurity CaSO ₄ (23) is suspended from the specific gravity salinity of 18% and the temperature of the function 15 is increased, and the impurities 23 are removed using a filter cloth. Further transfer the function 15 of the two-stage heating cooker (20). This process is repeated two or three times to reduce the fuel consumption while increasing the yield of salt.

The function (15) of the first stage heating cooker (24) after the removal of the impurities (23) begins to determine the specific salt salinity from 26%. When the burner's heating temperature is lowered rapidly, the bitter and astringent taste of the salt is reduced. MgCl ₂ MgSO ₄ precipitates with the brine and precipitates a good low salinity salt. The precipitated magnetic salt is immediately shipped (29) through the dehydration (26), drying (27), and packaging (28) processes.

As described above, the present invention can stably secure a high salinity function containing natural minerals regardless of seasons and weather by depositing a clay (mudflat soil) made by evaporating moisture with tillage to the function. This has the advantage of reducing labor than traditional suicide production. In addition, the sediment produced during the process of depositing the soil is completely discharged in two stages, and by controlling the heating temperature of the heating pot to remove impurities that rise above the boiling function, and additionally, the additional amount of water is used to reduce the fuel consumption and increase the production, thus producing a small amount previously. It is possible to mass-produce the traditional suicide.
