BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a ceramic having a far-infrared radiation characteristic, which is pressed into a surface portion of a wood block formed in a spherical or polygonal shape and sealed, and the wood block is used for cooking food. A wood block which is sometimes thrown into a pot, a pot or the like, or thrown into a beverage when drinking the beverage, and a method of processing the same. That is, the ceramic used in the present invention must be harmless to the human body.

Accordingly, the present inventor has selected and adopted alumina, titanium, silica, and magnesia ceramics as ceramics having no harm to the human body and having a high emissivity. Table 1 is a table showing the average emissivity of the above ceramics at normal temperature and at the time of heating (100 ° C.).

[0007]

[Table 1]

From the measurement results in Table 1, all the ceramics are 90% or more at room temperature and 91% at heating (100 ° C.).
The above high emissivity is shown, and can be adopted in the present invention.

Table 2 shows the results of measurements on characteristics of each ceramic employed in the present invention other than the far-infrared emissivity.

[0010]

[Table 2]

From the measurement results shown in Table 2, when magnesia was immersed in 1 liter of water in the above ceramics, 0.01 mg of magnesium was eluted in every 30 minutes, but ceramics other than the magnesia eluted mineral substances. Did not admit. In addition, 30 minutes after the water was heated to 100 ° C., the magnesia contained 0.02 mg of magnesium.
Eluted.

Further, in the ceramics, silica has a deodorization rate of 90% and 9% for ammonia and hydrogen sulfide, respectively.
Although it showed 3%, it had no antibacterial activity against Escherichia coli and staphylococci, and magnesia did not have too high deodorization rates against ammonia and hydrogen sulfide, 55% and 65%, respectively, and antibacterial rates against Escherichia coli and staphylococci, respectively. Both 94% and 95% were found to be very high.

However, it was found that the other ceramics, alumina and titanium, did not have deodorizing properties against ammonia and hydrogen sulfide, and had no antibacterial properties against Escherichia coli and staphylococci.

Therefore, which of the above ceramics should be used depends on whether the object food or drink is intended to emit far-infrared rays only, furthermore, elution of magnesium is required, and furthermore, deodorizing property is required. It is necessary to use differently depending on whether the purpose is deodorization and antibacterial property.

It is necessary to use a fine powder having a particle size of 5 μm or less for the ceramics having far-infrared radiation characteristics employed in the present invention to have a particle size of 5 μm or less in order to press-fit and seal the surface layer of the wood block.

The processing method of the present invention will be described based on the vacuum processing apparatus shown in FIG. First, ceramics having a far-infrared radiation characteristic and having a particle diameter of 5 μm or less are put into a stirring tank 1 together with water and a dispersant, and these are sufficiently mixed and stirred.
Then, the ceramic solution in a valve (slurry) state obtained by mixing and stirring in the stirring tank 1 is injected into the storage tank 4 of the vacuum processing machine 3 through the liquid feed pipe 2. A strainer 5 is provided between the liquid feed pipe 2 and the liquid storage tank 4 to remove dust and the like.

Next, a number of spherical or polygonal wood blocks to be processed are charged into a liquid injection tank 6 provided on the lower surface of the liquid storage tank 4 of the vacuum processing machine 3. The lid 7 is closed.

While the ceramic solution in the liquid storage tank 4 is injected into the liquid injection tank 6 through the injection pipe 8, the pressure in the liquid storage tank 4 and the liquid injection tank 6 of the vacuum processing machine 3 is increased. By the decompressor 9, preferably -1000 mmHg to -55
0 mmHg, particularly preferably -700 mmHg to -50
Set to 0 mmHg. When the pressure in the liquid storage tank 4 and the liquid injection tank 6 of the vacuum processing machine 3 reaches the above-described preferable pressure, so-called “fluff” is applied to the wall pore cells in the surface layer of the wood block inserted into the liquid injection tank 6. The phenomenon of “taki” (generally, a brushing phenomenon) occurs to open a wall hole. When this state is reached, the ceramic solution activated by the addition and mixing of the dispersing agent presses into the opened wall holes. The phenomenon of the "fluff brush" occurs approximately 0.5 times from the outer layer.
The range is about 0.7 mm.

Thereafter, the ceramic solution is transferred from the liquid injection tank 6 to the storage tank 4 by the drain pump 10 through the discharge pipe 11.
The return valve 12 is closed, and the inside of the injection tank 6 is again evacuated to remove the ceramic solution adhering to the surface layer of the wood block. Then, the removed ceramic solution is returned to the atmospheric pressure in the injection tank 6 and discharged into the storage tank 4, whereby the vacuum processing of the wood block is completed,
The lid 7 is opened and the treated wood block is taken out.

Next, since the wood block taken out of the vacuum processing machine 3 is immersed in a ceramic solution and contains a large amount of water, the wood block is loaded into a dryer and dried.

The wall hole is inserted into the injection tank 6 of the vacuum processing machine 3 so that the wall hole is opened in a “fluffy brush” state, and the wall hole after the ceramic solution is injected through the opening and penetrated is formed. In this drying step, the opening is closed by completely restoring the original state, and the ceramic is sealed in the wall hole of the surface layer of the wood block.

It is recommended that the ceramic be mixed with water and a dispersant in an amount of preferably 3 to 5% by weight, particularly preferably 4% by weight. It is not necessary to limit,
Preferably, it is recommended to use either sodium hexametaphosphate, Teepol or isooctane nonionic surfactant, and the amount added is 0.10-0.
It is preferably about 13% by weight, most preferably about 0.12% by weight.

The above-mentioned processing method is a processing method in which a ceramic solution is pressed into a wood block using a dispersant, but without adding a dispersant to the ceramic solution,
It is also possible to press-infiltrate the ceramic solution obtained by mixing only with water into the wall holes of the surface layer of the wood block. In this case, the time required for the ceramic solution to be injected and penetrated into the wall holes of the surface layer of the wood block is about twice as long as that when a dispersant is used.

Then, as a final step, since the wood block of the present invention is used for food and drink, a unique smell of wood is removed. That is, the dried wood blocks are
The smell of the wood is removed by boiling for about 20 minutes, and then it is placed in a dryer and dried to complete the processing of the wood block of the present invention.

The wood block processed by the processing method of the present invention has far-infrared radiation characteristics. FIG. 2 is a distribution diagram showing the average far-infrared emissivity of the wood block processed by the processing method of the present invention and the wood block before processing, and the far-infrared emissivity of the wood block by the processing method of the present invention is higher. Proven high.

As a material of the wood block of the present invention,
Cypress, cedar, hiba, tako and oak woods are preferred, and pine wood from tar can not be used. Furthermore, the shape of the wood block is
It is formed in a spherical shape or a polygonal shape, preferably a spherical shape, and its size is not particularly limited, but it is recommended to have a diameter of about 3 cm for convenient use. .

[0029]

Example 2 For each of the above ceramics, a case where an isooctane nonionic surfactant was used as a dispersant and a case where no dispersant was used were divided into two cases. Table 4 shows the results of measuring the penetration depth and characteristics of a spherical cypress block having an average diameter of about 3 cm obtained by processing the ceramic solution at the same concentration.

[0030]

[Table 4]

According to the measurement results in Tables 3 and 4, the wood block obtained by the processing method of the present invention has ceramics having far-infrared radiation characteristics sealed in the wall holes of the surface layer. It has been proved that each ceramic material imparts far-infrared radiation characteristics to the wood block.

In each of the ceramics described above, silica has a deodorizing property, and magnesia has an antibacterial property and a moderate deodorizing property. In addition to its properties, it has been proved that it is provided with deodorizing properties and also antibacterial properties.

When a wood block having the above-mentioned far-infrared radiation characteristic is put into a pot when cooking rice, for example, the activity of the water in the pot is increased by the action of far-infrared rays, and gas molecules such as oxygen and nitrogen are externally released. The power to take in appears, and the water becomes totally activated. When the water in the pot is heated, a high rate of far-infrared rays is radiated from the wood block, reaching the inside of the rice, causing internal self-heating, and as a result, the inside and outside of the rice are almost evenly uniform at the same time. Raise the temperature. Therefore, the temperature difference between the inside and the outside is eliminated, and more delicious rice can be cooked as the activated water.
In particular, magnesium is eluted from the wood block in which magnesia is sealed to produce good water, so that more delicious rice can be cooked.

In addition, when boiling noodles, making boiled food, and boiling vegetables, etc., the noodles can be squeezed by the same action as in the case of the rice, and the boiled food is finished with a rich flavor and fresh. You can keep vegetables in taste. In particular, magnesium elutes from the wood block in which magnesia is sealed, and the taste of noodles, boiled foods and vegetables is further improved.

When the above-mentioned wood block is put into alcohol, tea or coffee, the taste becomes mellow due to the action of far-infrared rays. In particular, magnesium elutes from the wood block in which magnesia is sealed, and the taste becomes more mild.

Further, when a wood block sealed with silica is introduced into a kettle when boiling water, hot water activated by the action of far-infrared rays can be obtained while removing the unpleasant smell in tap water by deodorizing action. . In particular, magnesium elutes from the wood block in which magnesia is sealed, so that more delicious hot water can be obtained.

Furthermore, in addition to far-infrared radiation characteristics and moderate deodorizing properties, wood blocks sealed with magnesia, which also has antibacterial properties, are poured into water to remove some of the odor in the tap water. At the same time, Escherichia coli and staphylococci can be sterilized, and the water can be made delicious by the action of far infrared rays and eluted magnesium.

As a material for sealing the ceramics,
Since the wood block is lighter in weight than water, the wood block rises to the top of the pot or pot when the food is cooked, and the drink can also be removed immediately because it floats on the top. There is no risk of accidental ingestion or ingestion, and there is no problem in safety.

[0039]
