Description
TECHNICAL FIELD

The present invention relates to amorphous silicon not containing tar, crystal and carcinogens which is porous and easily soluble in water and used for foods, medicines, cosmetics and feeds, a manufacturing method thereof and a manufacturing apparatus thereof.


BACKGROUND ART

Silicon is a useful material for rice cultivation and the growth of some agricultural crops and has been used as silicon fertilizer. In recent years, it has been pointed out that silicon is an essential trace mineral not only for agricultural crops but also for the human body, and it has been pointed out that the value as food, medicine and cosmetics is increasing.


Silicon (Si) is 25.8% in Clarke number, and it is the second most frequent substance after oxygen on the earth. Silicon has a lot of its solid as silicon dioxide (SiO2), but most of it is “crystalline”. On the other hand, silicon that is absorbed by humans and animals and plants is “amorphous” silicon, which is contained in diatomaceous earth, plants and the like. In addition, amorphous silicon not containing crystalline silicon is generally rare and expensive as crystalline silicon has been pointed out as carcinogenic to human body.


Rice hulls and rice straw contain a large amount of amorphous silicon. Many methods have been devised to obtain amorphous silicon by burning rice husks and rice straw. In the conventional process for producing amorphous silicon from rice hulls, in the case of obtaining rum hull combustion products, the rice husks are first fired in a fluidized bed burning furnace and then in an externally heated rotary oven a second firing There was a general way to create combustion products of shells.

which comprising,

Here, amorphous silicon which is a combustion product such as rice husks or the like is readily soluble in water even at a temperature within the range of 40° C. or less in the living body temperature.


A combustion device according to an embodiment of the present invention is a combustion device that burns rice husks or the like to obtain a combustion product such as rice hulls, wherein the combustion device is configured to rotate a rotary kiln or a screw Wherein a rotating shaft portion of the screw has a hollow portion, atmosphere or oxygen or a mixture thereof is introduced into the hollow portion, and exhaust gas generated upon combustion of the rice hulls or the like is supplied to a furnace And has an exhaust mechanism for discharging the exhaust gas to the outside.


EXAMPLE
Example 1


FIG. 1 is a diagram of an X-ray analytical spectrum of a combustion product of rice husks.


An X-ray analytical spectrum diagram in the case of combustion temperature 450° C., combustion temperature 550° C., combustion temperature 650° C., combustion temperature 700° C. are shown in order from upward in FIG. In either case, it is found that the shape of the X-ray analysis spectrum is a broad shape without a peak showing crystallinity, and the rice husks combustion product is amorphous.


Example 2


FIG. 2 shows the dissolution test results of the combustion product of the rice husks in purified water at 40° C.


From the test results shown in FIG. 2, it can be seen that the lower the production temperature, the better the water solubility. Also, in the case of “silica gel” which is one type of amorphous silicon, it is found that it is hardly dissolved. Considering the results of the X-ray analysis shown in FIGS. 1 and 2, even if it is amorphous silicon, not all of them are easily water-solubilized but their properties are greatly different depending on the production temperature and the manufacturing method. Although the manufacturing temperature is low, shell-flame burned materials have high water solubility, but the production time is long and economic efficiency is not excellent. Also, if it is below 500° C., it is likely to produce benzotriazole which is a carcinogenic substance, so it is not suitable for edible use. When the production temperature is high, the production becomes easy, but the water solubility becomes low. It is generally considered that the combustion product of the rice husks exceeding 800° C. will crystallize, and crystalline silicon is also considered to be carcinogenic, so it is also not suitable for edible use.


Therefore, amorphous silicon which does not contain carcinogens and has high water solubility means that the temperature is as low as possible at a production temperature of 500° C. or higher. Considering the production efficiency for this, the optimum production temperature for practical use is in the range of 550 to 650° C.

Various analyzes were carried out on amorphous silicon obtained from rhinoceros burned material at a combustion temperature of 600° C. A series of results will be described. The inspection agency is Japan Food Function Analysis Research Institute Co., Ltd.

Using the amorphous silicon-containing rasp shell combustion product of the present invention as a specimen, in accordance with the OECD Guideline for the Testing of Chemicals 404 (2002), a skin primary irritation test using a rabbit was performed.


The specimens were closed to the intact and scarred skin of 3 rabbits for 24 hours. As a result, 1 hour after removal, very mild to clear erythema was seen in all cases, and in 2 cases very mild edema was seen but disappeared by 72 hours.


ISO 10993-10 Biological
Evaluation of Medical

The primary irritation index (PII) obtained according to Devices—Part 10 (2010) was 0.4.


From the above, in the primary skin irritation test using rabbits, specimens were evaluated as falling within the category of “nonirritating”.


Acute oral toxicity test (limit test) using rats was conducted using the amorphous silicon-containing burned rice flour sample as a specimen of the present invention. Samples at a dose of 2,000 mg/kg were orally administered to the test group to male and female rats as water control for solvent control as control group and observed for 14 days. As a result, no abnormalities and deaths were observed during the observation period. From the above, it was evaluated that in a single oral administration using rats, the LD50 value of the specimen exceeded 2,000 mg/kg in both males and females.


Example 4
Application to Food and Medicine

The amorphous silicon of the present invention is effective for improving the bone density of the human body. Subjects From the age of 40 to the age of 80, the bone density tended to rise as a result of giving the amorphous silicon of the present invention every day. Application as a supplement to improve bone density is also possible.


Table 10 shows that bone density before and after ingestion is measured by ingesting about 100 mg of amorphous silicon containing powder of the present invention (silicon content 40% or more) in 10 males and females age 45 to 82 years a day It is the result.


Here, Table 10 shows the ultrasonic bone density measurement result of the bone of the subject's heel.
