Description

  The present invention relates to a method for producing drinking water using a baked shellfish.

  As a standard for evaluating water quality, for example, an oxidation reduction potential (hereinafter referred to as “ORP value”) is known. The ORP value of tap water is often about +450 mV to +550 mV, but may reach +750 mV.

On the other hand, it is considered that the ORP value of drinking water is preferably +200 mV or less. In contrast, so-called oxidized water having an ORP value exceeding +200 mV, such as the above-mentioned tap water, is said to have adverse effects on animals and plants, including humans, when used as drinking water, and it also corrodes metals such as iron. It can also be a cause.

Therefore, in order to solve the above problems, means for electrically treating water, for example,
[1] A water treatment apparatus for aggregating and filtering a suspension contained in water by disposing an electrode pair in the middle of a water channel and applying a direct current to perform electrolytic treatment (see, for example, Patent Document 1). Or
[2] A water conditioner that lowers the ORP value of water by using a granular or fragmented ceramic capacitor as a charge body of protons and electrons generated by electrolysis of water (for example, see Patent Document 2).
Has been proposed.

  However, the conventional techniques as described above are economically problematic because the cost for facilities for electrical treatment of water is high. In addition, there is a problem in that the operation and maintenance of facilities in the electrical treatment of water are complicated. Furthermore, although the ORP value can be lowered by electrical treatment of water, there is a problem that it is impossible to produce drinking water that can promote health because other components cannot be added to the water.

  This invention is made | formed in view of the above situations and problems, and it aims at providing the method which can manufacture the drinking water which can improve health simply and cheaply.

  1st invention for achieving the said objective repeats the process which bakes a shell at 1800-2000 degreeC, and is left to cool to normal temperature at least twice, and the obtained baked product and water are 1: (10-10 40) The mixture is boiled, and the resulting mixture is boiled and concentrated until the weight of the mixture becomes 1/2 or less of the weight before boiling, and the concentrated mixture is filtered.

  According to a second aspect of the present invention, a carbide obtained by compressing and carbonizing sawdust and the shell are housed in a firing furnace, and the shell is fired at 1800 to 2000 ° C. by burning the carbide.

  According to the first invention, the odor peculiar to the shell can be completely eliminated, and the shell can be powdered without being separately pulverized by a pulverizer. And it can be manufactured at low cost. Moreover, if the shell as waste is reused, it can also contribute to the reduction of waste.

  According to the second invention, the shell can be fired more easily and inexpensively.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the manufacturing method of the drinking water 1 which concerns on this embodiment has a baking process (P1-P4), a mixing process (P5), a boiling process (P6), and a filtration process (P7). Yes. That is, in this manufacturing method, the process of baking the shell 2 at 1800 to 2000 ° C. and then allowing it to cool to room temperature is repeated, for example, twice (P1 to P4), and the obtained fired product 3 and water are 1: (10 -40) Mix in a weight ratio of [1:10 to 1:40] (P5), boil the resulting mixture 4 and concentrate until the weight of the mixture 4 is less than or equal to 1/2 the weight before boiling. (P6) The mixture 4 after concentration is filtered (P7). Next, each step will be described in detail.

[Baking process]
In producing the drinking water 1, the shell 2 is first baked (P1) at 1800 to 2000 ° C. for 1 hour or more, preferably 2 hours or more, and then allowed to cool to room temperature (P2).

  The term “shell” as used herein refers to a shell portion obtained by removing shell meat from an edible shellfish. Examples of shellfish include oysters (oysters), scallops (scallops), swordfish (clams), abalone (clams), and turban shells. If the shell 2 that is discarded as waste after removing the shell meat is used, there are advantages that raw materials can be obtained in a large amount at a low cost and that the waste can be effectively used. The shell 2 is preferably washed with water or the like before firing to remove dirt. Further, instead of or together with the shell 2, a sea urchin shell and / or a crab shell may be used.

  The shell 2 may be fired in a state where it is housed in a firing furnace having an appropriate heat source, but the carbide 2 obtained by compressing and carbonizing sawdust and the shell 2 are housed in the firing furnace, and the carbide is burned. If the shell 2 is fired at 1800 to 2000 ° C., there is an advantage that the shell 2 can be fired more easily and inexpensively. The reason for firing at 1800 to 2000 ° C. is because it is suitable for carbonization of the shell 2. This is because if it is 1800 ° C. or lower, it is not sufficiently carbonized, and if it is 2000 ° C. or higher, it does not remain as ash. The carbide obtained by compressing and carbonizing sawdust (large sawdust) is a carbide obtained by further carbonizing wood solid fuel [for example, Ogarite (trade name)] obtained by compressing sawdust into a rod shape [for example, Oga charcoal (trade name)], etc. Is mentioned.

  Next, the fired product 3 after being allowed to cool is fired again at 1800 to 2000 ° C. for 1 hour or longer, preferably 2 hours or longer (P3) and then allowed to cool to room temperature (P4).

  In this way, if the baking at 1800 to 2000 ° C. is repeated twice, the odor peculiar to the shell 2 can be completely eliminated, and the shell 2 can be powdered without being separately pulverized by a pulverizer. There is an advantage. In addition, you may repeat 3 times or more as needed above baking and standing_to_cool.

[Mixing process]
And the obtained baked product 3 and water are put into a boiling container, and it is set as the mixture 4 (P5). The weight ratio of the fired product 3 to water is 1: (10 to 40) [1:10 to 1:40]. As water, soft water such as groundwater is suitable. Soft water here refers to water having a hardness of 10 degrees or less. This soft water contains less calcium ions, magnesium ions, etc. than hard water and does not contain as much chlorine component as tap water, so if soft water is used, the minerals in the calcined product 3 There is an advantage that the components are easily eluted in water. When the amount of water to be added is small, the ORP value of the drinking water 1 obtained is lower, but when the weight ratio is less than 10, it is almost the same and the production efficiency is poor, so 10 is set as the lower limit value, and the weight ratio is 40 This is because when the value is larger, the ORP value becomes smaller and the effect becomes smaller.

[Boiling process]
Next, the obtained mixture 4 is boiled and concentrated until the weight of the mixture 4 is ½ or less of the weight before boiling (P6). That is, the water in the mixture 4 is evaporated by boiling until the weight of the mixture 4 becomes 1/2 or less. Thereby, the mineral component in the baked product 3 of the shell 2 can be sufficiently eluted in water.

[Filtration process]
And if the mixture 4 after boiling is left to cool to normal temperature as needed and filtered (P7), a residue and the drinking water 1 can be isolate | separated.

  The drinking water 1 obtained as described above contains a mineral component eluted from the calcined product 3, has an ORP value of −400 mV or less, which is significantly lower than +200 mV, and has a bactericidal effect. Further, the drinking water 1 has no odor. The filtered residue can be used as a soap, a hair washing agent, a bath agent or the like.

  Thus, according to the manufacturing method as described above, the odor peculiar to the shell 2 can be completely eliminated, and the shell 2 can be powdered without being separately pulverized by a pulverizer. There is an advantage that the drinking water 1 capable of improving the temperature can be manufactured easily and inexpensively. Further, if the shell 2 as waste is reused, there is an advantage that it can contribute to reduction of waste.

[Example 1]
(1) After washing 50 kg of oyster shells, Oga charcoal (trade name) was burned and placed in a furnace to keep the furnace temperature at about 1900 ° C. and baked for 2 hours. After that, the OG charcoal is naturally cooled with natural digestion of the OG charcoal while being kept in the furnace to maintain the state where the temperature is lowered to room temperature for about half a day, and then the OG in the furnace containing the cooled oyster shell. Charcoal was added, burned again and heated until the furnace temperature reached about 1900 ° C., and this temperature state was maintained for about 3 hours and fired. And this was naturally cooled to room temperature in the state where it was put in the furnace like before, and the baked material of the oyster shell was obtained. The weight of the fired product at this time was 410 g. (Steps P1 to P4)

(2) 8L of ground water is added to 410g of the fired product and mixed well (P5), and the mixture in a cloudy color is placed in a boiling vessel and heated without boiling to evaporate the water ( P6) When the total weight was about ½ before boiling, the heating was stopped and the mixture was allowed to cool to room temperature.

(3) The naturally cooled mixture was filtered to obtain about 3.8 L of target drinking water. FIG. 2 shows the result of analyzing this drinking water [spectrum chart by energy dispersive X-ray analyzer (manufactured by Horiba, Ltd.)].

(4) Although the residue filtered off is moist white powder, this powder contains a lot of Na and K, so use it in livestock feed or in a bath. Can do. When used as a livestock feed, the growth and health of the livestock can be maintained, and when used as a bath bath, it has effects such as gloss on the skin. Furthermore, since the same component as the drinking water still remains in the powdery material, the same drinking water could be obtained by adding water again, mixing, heating and boiling, and filtering. .

[Example 2]
The same operation as in Example 1 was performed using 50 kg of a mixture of abalone shell and scallop shell. The analysis result of the drinking water thus obtained [spectrum chart by energy dispersive X-ray analyzer (manufactured by Horiba, Ltd.)] is shown in FIG.

  As mentioned above, the manufacturing method of the drinking water which concerns on this invention is suitable for manufacturing the drinking water which can improve health simply and cheaply.

It is a flowchart which shows the manufacturing method of the drinking water which concerns on embodiment. It is a spectrum chart by the energy dispersive X-ray analyzer of the drinking water obtained in Example 1. It is a spectrum chart by the energy dispersive X-ray analyzer of the drinking water obtained in Example 2.
