Abstract

Seawater is concentrated by any known method to its point of saturation in sodium chloride, the potassium sulphate is removed, and the seawater is then heated to boiling at atmospheric or higher pressure and subsequently spray dried in a vacuum or at atmospheric pressure using known apparatus. Extremely fine crystals or a white powder are thus obtained, depending on the evaporation equipment used. The salt produced in this way is very hygroscopic, and is packed in airtight plastic or aluminium containers. When extracting the sea salt, 2.5 litres of salt-free water are obtained for each kilogramme of salt.

Description

Obtaining total, natural, organic sea salt by total evaporation of sea water with simultaneous production of salt-free water

The invention relates to the way of obtaining total, natural, organic sea salt, i.e. as nature provides us, with simultaneous production of salt-free water.

Sea water, untouched by human activity, is a natural solution of mineral salts 3rd part, similar to the composition of blood serum, a fact that supports the theory that the life of mammals originated from the sea. The embryos of the mammals arise and grow in a watery medium - the amniotic or amniotic fluid - e.g. Partly similar to the sea water, of course in a much stronger dilution. The last contains more than 32 elements - chlorides, sulfates, iodides, bromides of sodium, potassium, calcium, magnesium and trace elements of zinc, selenium, boron, fluorine, lithium, strontium, phosphorus, barium, rubidium, aluminum, gold in colloidal form uma-.

All of the above components, with the exception of calcium sulfate, are not only beneficial and indispensable for the harmonious function of the human organism, but are also in the most ideal relationship to one another.

Sea water has been used for therapeutic purposes in the form of drinks or syringes since ancient times. At the beginning of our century, its use in biological medicine and homotherapy was introduced. Incidentally, it should be noted that the physiological serum is nothing more than a weak solution of sodium chloride.

Since the beginning of its creation, man has felt the need to use sea salt - "the salt of the earth" - as an indispensable addition to his food. He took his salt from the sea without much thought about its purity, ie its content with elements other than sodium chloride, as nature offered him abundantly, ie from the deepening of the rocks and areas that were washed away by the sea. Modern man, however, many years ago left the traditional way of finding and preserving his food, which he inherited from generation to generation, and with a quick step he went to the great mistake of refining his varied food. Its daily salt, however, became the victim of these destructive tendencies much earlier, in that man has been creating organized salt pans for more than a century, where the sea water is influenced by the sun's rays or later by technical means Agent evaporated. He collected and despite the technological progress he still collects the pure and dazzling white salt - the sodium chloride - which secondly crystallizes before all other salts contained in the sea water. This crystallization preceded, in the first phases of evaporation from the sea water, the excretion of the calcium sulfate which is useless for food, which it naturally throws off, and began to become problematic with the shedding of the remains of the sodium chloride crystallization - i.e. the mother liquor of the sodium chloride crystals, which all other salts and trace elements that are present in the sea water contains -. With his knowledge at the time, he regarded the above components as harmful to humans, which would have to be removed from the sodium chloride salt, if not for other reasons, at least because in this way the requirement for his knowledge at that time was essential a non-deliquescent salt could be ensured. (As is known, the flow of the impure sea salt is due to the presence of the hygroscopic magnesium chloride).

However, throwing off the "mother liquors" created ecological problems in the areas of the salt pans and the related technological world literature is overflowing with reports of this endeavor by humans to avoid this ecological contamination and at the same time to economically exploit the wonderful raw material source which the "mother liquors" represent.

In summary, it can be said that this effort - apart from a few traps, such as the extraction of magnesium, which no longer takes place from the "mother liquors" but directly from the sea water - has failed internationally.

As can be seen from the above, it is questionable how modern man has not yet thought of using the sea to extract his daily salt in the way that nature offers him. together with the sodium chloride, also to take away all the valuable constituents that the sea contains and at the same time to get rid of the problem of eliminating the "mother liquors".

Filling this gap is the aim of the present procedure, which should be interpreted as follows:

The evaporation of the sea and the excretion of calcium sulphate is carried out as today in the salt pans or in some technological way up to the saturation point of the thickened sea water in sodium chloride. In contrast to the previous practice, the above-mentioned sea lye saturated with sodium chloride no longer becomes the crystallized ponds of the salt pans or the modern evaporation apparatus used today ten further evaporation and removal of pure sodium chloride crystals and subsequent repulsion of the "mother liquors", but the above saturated sea lye is heated to the boiling point under atmospheric or higher pressure and rapidly and totally - to dry - by spraying in a device for rapid and total Evaporation evaporates.

Such technology provides us with numerous types of modern technology. The above process for the extraction of sea salt not only results in a biologically higher product than today's processes, but also has the advantage of lower production costs, because three production phases of the old processes, mainly the crystallization of sodium chloride , its cleaning and the removal of the "mother liquors" fall away. At the same time, in the above-mentioned apparatus, due to the appropriate cooling, of the water vapors to be removed during the rapid and total evaporation, salt-free water is obtained in a ratio of 2.5 liters of water per 1 kg of total, natural, biological sea salt.

This salt is in the form of fine white crystals or a white powder, depending on the type of equipment chosen for rapid and total evaporation. Of course, it is very hygroscopic due to the presence of magnesium chloride and this property cannot be eliminated by any physical or chemical ingredient without undesirable side effects. To make it easier to use, its airtight packaging is attached in the well-known plastic or aluminum cans, which keep their contents airtight, even after the closure has been torn off.

These devices are abundantly offered to us in various types by modern technology. In this way, the finest white crystals or a white powder are obtained, depending on the type of equipment used for rapid and total - up to dry - evaporation.
