Description

High purity functional alkaline mineral salt and manufacture method thereof and device thereof

Technical field

The present invention relates to a kind of high purity functional alkaline mineral salt and manufacture method thereof and device thereof, particularly relate to a kind of mixed process, reach and under the low temperature that does not produce dioxin, carry out the process that heat drying obtains the functional alkaline rock salt, make the method for high purity functional alkaline mineral salt and high purity functional alkaline mineral salt and its manufacturing installation that Using such method is made by filter process, loess water manufacture process, functional materials manufacturing and interpolation process, filtered brine and loess water.

Background technology

Existing common process salt is to make by high-temperature heat treatment, so the dioxin of build environment hormone in its manufacture process, and because of harmful substances such as heavy metal harmful.

For addressing the above problem, and produce the salt that more is of value to human body, the present invention adopts the heat treated particular method of manufacture of non high temperature to make salt, thoroughly solved the danger that generates dioxin, thereby removed fully harmful substances such as poisonous dioxin of human body and heavy metals, and by the assorted method of the system that is rich in multiple mineral matter to the human body beneficial, produce high purity functional alkaline mineral salt, not only brought into play the function of original flavoring, also carry out the heavy metal to be concentrated in human body and metabolin function (detoxication), thereby high purification function alkalescence hydrophily rock salt and its manufacture method and manufacturing installation to the human body beneficial are provided to external discharge.

In the middle of our daily life, salt is indispensable necessary seasoning, plays the important function that improves food fragrance.The sea salt that utilizes natural conditions concentrated seawaters such as solar energy, wind and make is rich in various mineral matters such as calcium, magnesium, iron, manganese, phosphorus, sulphur, and this mineral matter plays crucial effects to the vital movement of human body.But for purified salt, the general ion-exchange membrane type purified salt of having removed above-mentioned necessary mineral matter in for edible subtractive process only has been left the salty composition of salt, therefore, not only human body is not had any benefit, can cause various side effects on the contrary.In order to remove the harmful substance in the salt and to form alkaline components and carry out high-temperature heat treatment, and there is the danger that generates dioxin in the refined salt of producing by high-temperature heat treatment process particularly, so more fatal.In view of this, though salt plays indispensable effect in people's dietetic life, the heavier Chinese people of particularly suiting one's taste has the problem that causes various adult diseases etc. because of the too much absorption of salinity.

But recently along with the progress of culture and the raising of level of consciousness, and the variation of people's cooking culture, most consumers not only requires the good property of its taste and quality, also requires functional as healthy food.Therefore, occur not only bringing into play its original taste also beginning on the market, also be rich in the functional salt such as salt of the various mineral matters that are of value to human body.

The kind of salt has the rock salt of 1. taking in rock; 2. the sea salt that evaporates seawater and obtain; 3. the mechanical salt that utilizes amberplex and obtain; 4. the refined salt of processing above-mentioned rock salt or sea salt and obtaining etc., the manufacture method of refined salt particularly, along with the development of industrial technology as mentioned above and the consumer demand that improves day by day, the manufacture method that breaks away from simple heating, be replaced by the method that is added with the various functional materials that benefit human body gradually, the example is exactly the refined salt that bamboo salt, loose salt, loess salt, green tea salt etc. have added functional materials.

But this class refined salt is not a best solution yet.Refined salt is that the acid ingredient with salt is converted to alkaline components, and in order to keep the necessary mineral composition in the salt, remove toxicity such as various impurity and heavy metal, in its manufacture process, raw material salt is carried out high heat treatment by methods such as stir-fry, burning, fusions, therefore, exist the generation dioxin fatal, and be lost the problem of human body beneficial's mineral matter to human body.

As writing in many papers, the toxicity harmful substance that produces when dioxin (dioxin) is heated to more than 300 ℃ for the material that has the chlorine atom is a representative environment hormone of upsetting human hormone's normal activity.If absorb a large amount of such dioxins, will be carcinogenic, reproductive function descends, and can also bring pernicious influence to the neonate by placenta or breast milk.From the thermodynamics angle, dioxin is difficult to destroyed under the high temperature more than 700 ℃, even under high temperature more than 1200 ℃, also there is the part survival to be difficult to destroy, therefore, caused increasing in a large number of dioxin content according to the above-mentioned refined salt that is heated to the manufacture method manufacturing in the past more than 300 ℃, even under 800 ℃ of conditions, fire 8 times, and under 1300 ℃ of conditions, fire the 9th time and the bamboo salt made also can't be avoided the generation of dioxin.

Recently, the investigation result of food pharmaceuticals State Security Department (the food medicine Room) also demonstrates the problems referred to above, and these facts have become the focus of paying special attention in the society, need to improve as early as possible.Investigation result according to the food medicine Room, in 67% heat treated salt, detect a large amount of dioxin compositions, its average detected amount reaches 11.09pg, be up to 43.54pg, this average detected amount has surpassed 2000 and 7.6 times of the fish dioxin average residual allowance of the domestic peak of Korea S that calendar year 2001 is investigated out at least.

The 1g dioxin can cause death 20,000 body weight for the 50kg standard adult, its toxicity substantially exceeds 10,000 times of potassium cyanide, therefore is called as the utmost point toxicant that the mankind produce.But, according to the investigation result in the food medicine Room, do not contain dioxin without the crude salt of heat treated, therefore absorb and have no effect.

Summary of the invention

The present invention draws in order to solve the problem in the above-mentioned existing refined salt manufacture method, thoroughly reduces the not only economy of generation of dioxin but also the production technology of environmental protection in the production that its purpose is to be provided at refined salt and the relevant overall process.

Another object of the present invention is to provide a kind of high purity functional alkaline mineral salt, it not only has the original function as flavoring, also be rich in the various mineral matters or the physiological activator that are of value to human body, and by avoiding the safety in production method of high-temperature heat treatment process, ackd salt is converted to the basic salt that helps human body, can also realizes the heavy metal of accumulation in the body and the external discharge function (detoxication) of metabolin simultaneously.

According in order to solve one embodiment of the invention of above-mentioned technical task, the manufacture method of high purity functional alkaline mineral salt is as follows.

I. the manufacture method of high purity functional alkaline mineral salt comprises: filter process, loess water manufacture process, the 1st mixed liquor manufacture process, dry run and functional alkaline rock salt acquisition process.

A) in above-mentioned filter process, for example 1. sea salt is dissolved in the water; Or 2. will fire salt and be dissolved in the water; Or 3. bamboo salt is dissolved in the water; Or 4. mechanical salt is dissolved in the water; Or the seawater that 5. use to concentrate, will import lautertuns at the salt solution that 1. produces in 5., remove the harmful substance of proportion by precipitation (sedimentation and filtration stage), by the harmful substance of (suspension filtration stage) removal proportion that suspend less than water greater than water.

Here, harmful (toxicity) material not only is meant dioxin and heavy metal, is that not to be contained in the salt as mud, sand, impurity (suspended material) etc. be the general name of good all contaminations matter.

Above-mentioned lautertuns is that the jar, open cylindrical shape or the rectangle tank in top that are formed with inflow entrance and flow export are good, can add filtering agents such as active carbon, hard charcoal, common charcoal or loess ball in inside.And, trickle loess can also be made stratiform and be used as filtering agent and be suitable in the lump.That is to say that water will pass through loess formation when the bottom of lautertuns pours into, at this moment impurity in the water or pollutant are decomposed, and bring more significant filter effect because of the microorganism in the loess formation.At this moment, also can obtain loess water without special loess water manufacture process, can also in addition additional loess water manufacture process in order to obtain better loess water.Harmful components in the salt can be adsorbed in thus on the above-mentioned filtering agent, when removing impurity more efficiently, can also obtain mineral matters such as the mineral that are dissolved out from filtering agent and alkaline components and permeate double effects in salt solution.At this moment, salt solution slowly pours into from the position of approaching the lautertuns bottom, to avoid being deposited in the harmful substances such as heavy metal of bottom along with current float up again.

Particularly form the inflow entrance that salt solution flows in the lautertuns bottom, that more effectively filters the reasons are as follows.If flow into salt solution from lautertuns top, then heavy material can be filtered net and filter out, but the less suspended material of proportion is subjected to from top to bottom hydraulic pressure and gravity effect, together pass through screen pack with salt particle, can't be filtered net filters out, therefore, finally can be filtered the just bigger harmful substance of proportion of net filtration, can't realize effective filtration.

But, the lautertuns of functional alkaline rock salt manufacture method among the present invention, salt solution is slowly poured into from the lautertuns bottom, thereby the precipitated filtration of heavy harmful substance, and can not be subjected to the influence of current and float up again, and the less harmful substance of proportion can be filtered the filter membrane on agent and top and filters, and therefore has more significant clean-up effect.

Above-mentioned filter membrane can be multilayer filter paper.This filter paper can use normally used coffee filter paper or textile cloth.

The best approach is, according to its function precipitation Cao or the lautertuns that lautertuns is divided into ordinary construction is provided with, and a plurality of lautertuns of connecting, precipitation Cao and lautertuns and improve the clean-up effect of salt solution.

B) in above-mentioned loess water (encourage water) manufacture process, the loess of the exquisiteness that will draw with sieve is diluted in the water purification in the stillpot and after placing a period of time, (precipitate phase) gets the upper strata liquid of this stillpot top section when heavy loess powder is deposited in the stillpot bottom to a certain degree, thereby obtains the loess water of purification.

In order to obtain more peace and quiet loess water, can repeatedly repeat above-mentioned filtration and precipitation process.In this filter process, can utilize to have 20 ℃～the electro-heat equipment heat supply of 100 ℃ of following temperature, make that mineralogical composition in the loess water more dissolves easily in water, improve the efficient that functional salt is made among the present invention.Use the electro-heat equipment heat supply of 80 ℃～90 ℃ of following temperature to be the best here.If its temperature is less than 20 ℃, then the mineralogical composition in the loess water is difficult for dissolving, if greater than 100 ℃, then water will seethe with excitement, and can't obtain clean loess water.

The loess water that obtains in the said process can directly use, but in order to shorten the processing time in the technology of back and to enhance productivity, can increase the process of the moisture in evaporation, the above-mentioned loess water of removal again.And, as previously mentioned, when can replace filtering agent to filter, make loess water with trickle loess formation.Also can increase other loess water manufacture process in order to obtain better loess water.

C) above-mentioned the 1st mixed liquor manufacture process is for mixing purification salt solution of making in the above-mentioned filter process and the purification loess water that obtains in loess water manufacture process, make the process of high purity functional alkaline mineral salt manufacturing, can add in this mixed liquor and drop into liquid or pulverous functional materials with mixed liquor.

The kind and the proterties that devote the functional materials in the above-mentioned mixed liquor can be changed arbitrarily according to manufacturer or consumer's requirement.For example, will promote human body metabolism and help to make powder and use to the green tea of external discharge metabolin, perhaps use boil green tea and tea (functional materials manufacture process).

In addition, also can earlier the above-mentioned functions material be mixed in salt solution (seawater) or loess water after, mix with other solution again.

D) above-mentioned functions alkalescence rock salt acquisition process is, air dry or under sunshine 20 ℃～120 ℃ temperature, best is the mixed liquor that heat drying is made in the 1st mixed liquor manufacture process under 30 ℃～50 ℃ conditions, the salt component that is dissolved in this mixed liquor and the mineralogical composition in loess and the active carbon are set in together, separate out the process of functional alkaline rock salt.Another kind method is at first under 30 ℃～50 ℃ temperature, and heat drying and after separating out salt, in order to remove residual moisture, be heated to the temperature more than 1000 ℃ obtains the high purification function alkaline mineral salt etc.

Why with the heating and temperature control of mixed liquor below 120 ℃, be that evaporation is also accelerated because temperature is got over high-moisture, the time of separating out of high purity functional alkaline mineral salt shortens, but temperature get over high alkalinity and weaken, thereby can't generate product of the presently claimed invention.If be below 20 ℃, then required height purifies the overlong time of separating out of alkaline functional rock salt, and whole efficiency descends.Therefore, 30 ℃～50 ℃ is optimum temperature.Why optimum temperature being controlled at 30 ℃～50 ℃, is to generate dioxin in the heating process because of can thoroughly being breaking at, and can keep the alkaline components of salt.And, by heating, promote separating out of salt, thereby alkalescence and mineralogical composition are rich in the shortening of production time with proper temperature, be very effective technology.

E) last, the functional alkaline rock salt of pulverizing macrocrystalline shape improves commodity.

II. different with said method (I), functional alkaline salt of the present invention can be made by loess water manufacture process, the 2nd mixed liquor manufacture process, dry run and functional salt acquisition process.

A) in another embodiment of the present invention, loess water manufacture process is identical with method in above-mentioned (I), introduces no longer in detail at this.

B) above-mentioned the 2nd mixed liquor manufacture process, be in the purification loess water that in loess water manufacture process, obtains 1. dissolving salt, bamboo salt, fire salt; Or mix 2. salt solution; Or 3. concentrated seawater, obtain after the 2nd mixed liquor, the 2nd mixed liquor is imported the process of removing the various toxicity harmful substances in the 2nd mixed liquor in the lautertuns.

Here, structure of above-mentioned sedimentation and filtration groove etc. is identical with the record in the method (I).

And, also can drop into functional materials in the 2nd mixed liquor.

C) acquisition process of above-mentioned functions alkalescence rock salt, it is the mixed liquor that air dry is made in the 2nd mixed liquor manufacture process, or 20 ℃～120 ℃ temperature, the best is heating and dry this mixed liquor under 30 ℃～50 ℃ conditions, thereby obtains the process of functional alkaline rock salt from the 2nd mixed liquor.

This process also can have aforementioned various feature.

D) the functional alkaline rock salt that obtains by said process is the granule that trickle powder maybe can be pulverized.

The another kind of embodiment of the manufacture method of functional alkaline salt III. of the present invention comprises: 1 filter process, 2 filter processes, dry run and functional salt acquisition process.
