Description

Manufacturing method of water-soluble shell powder using shell and water-soluble shell powder produced thereby {Manufacturing method of water-soluble shell powder using shell and water-soluble shell powder produced by the same}

The present invention relates to a method for producing water-soluble shell powder using shells and to the shell powder produced thereby. More specifically, the present invention relates to shellfish (oysters, clams, cockles, abalone, conches, clams, etc.) After firing at temperature, time, oxygen injection amount, and time intervals, it is manufactured into a white oxidized mineral powder that dissolves in water within 24 hours, thereby helping the growth of humans, animals, plants, and harmful bacteria. When the manufactured water-soluble shell powder is dissolved in water and then vinegar or citric acid is added, it becomes colorless, odorless, white, clean water with no residue. In addition, it is absorbed quickly into the body, and even if a large amount is ingested, the body absorbs only an appropriate amount and the rest is excreted. It relates to a method of manufacturing water-soluble shell powder using shells.

Our country is surrounded by the sea on three sides, so fish and shellfish have been important food resources since ancient times and an important source of high-quality protein and lipids, as well as vitamins A, D, B2, and the mineral calcium (Ca).

Accordingly, in the case of shellfish, hundreds of thousands of tons of shellfish are produced every year. In particular, approximately 300,000 tons of oyster shells are produced in Gyeongsangnam-do alone, which accounts for more than 60% of the national oyster production, and in the case of Jeollanam-do, oyster shells are produced annually due to shellfish farming and processing. More than 100,000 tons of shellfish are produced.

About 50% of these shellfish are used for seedlings and 10% as fertilizer, but about 40% of the remaining amount is landfilled on the coast or disposed of in the open air, emerging as a serious environmental pollution problem along with bad smell.

As a way to recycle these shellfish, they can be manufactured into external skin compositions (e.g., Publication Nos. 10-2010-0019737 and 10-2011-0086894) or wooden panels (e.g., Registered Patent Publication No. 10- 1614502), building materials (e.g. Registered Utility Model Publication Nos. 20-0165053 and 20-0374493, and Publication Patent Publication No. 10-2008-0017068), paints, artificial reefs and fishing gear, tetrapods, desulfurizing agents, water It is currently being used in a variety of products and industries such as purifiers, feed, snow removal materials, and road construction.

Looking at the recycling plan for shells used in various products and industrial fields as described above, basically, shells are powdered and mixed with other compositions for use. The method of manufacturing shell powder mainly involves a washing step and a baking step. It is used after being powdered to the desired particle size through a grinding step.

However, as seen above, despite the various recycling methods for shells described above, recycling of shells is still not carried out properly, and a large amount is landfilled and disposed of in the open air.

This is because, firstly, there is no company that can take the lead in mass processing this because of its low economic feasibility, and secondly, there is a technology that can classify the collected shellfish into the desired particle size according to various recycling methods and provide the shell powder to each recycling company. This is because it is not provided.

In other words, when recycling using shellfish in the various products and industrial fields described above, there is a need for technology that can process large quantities of shell powder, which is the raw material, and efficiently provide it to each company.

Therefore, shellfish are being utilized through a method of producing shell powder containing mineral components. The conventional method of manufacturing shellfish into shell powder containing mineral components is usually 8 times at a high temperature of 1200°C to 1500°C. A method of producing shell powder of ionized mineral components is being applied by baking for ~15 hours and making powder by machine into nanoparticles.

However, the shell powder containing mineral ingredients using conventional shellfish as described above is water-soluble, and when dissolved in water and then added with vinegar or citric acid, heat, odor, and gas are generated, and residues remain, which causes gas in the stomach when consumed by humans. When encountering stomach acid, the above phenomenon occurs.

Moreover, due to the above-mentioned phenomenon, there were problems such as indigestion, gas generation in the stomach, and gallstones due to waste when ingesting large amounts.

Therefore, if you dissolve the mineral ingredient in water and add vinegar or citric acid, it turns into colorless, odorless white clean water with no residue. It is quickly absorbed into the body and has a shell that allows the body to absorb only an appropriate amount and excrete the rest even if a large amount is ingested. There is a need for research and development on the manufacturing method of the water-soluble shell powder used.

Another purpose of the technology according to the present invention is to bake shellfish (oysters, clams, cockles, abalone, conches, clams, etc.) in a kiln using physical and electrical methods at intervals of temperature, time, oxygen injection amount, and time. By dissolving the water-soluble shell powder in water and adding vinegar or citric acid, it turns into white oxidized mineral powder that dissolves in water within 24 hours. When vinegar or citric acid is added, it turns into colorless, odorless, white clean water with no residue. In addition, it is absorbed into the body quickly and in large quantities. Even when ingested, the body absorbs only an appropriate amount and the rest is excreted.

As shown in Figures 1 to 9, the method for producing water-soluble shell powder using shells according to a preferred embodiment of the present invention involves firing the shells in a kiln using physical and electrical methods at intervals of temperature, time, oxygen injection amount, and time. It is manufactured to become a white oxidized mineral powder that dissolves in water within 24 hours, including a washing step (S1), initial natural drying step (S2), firing preparation step (S3), first temperature increase step (S4), 1 Secondary oxidation stage (S5), secondary oxidation stage (S6), constant temperature maintenance stage (S7), intermediate natural drying stage (S8), second temperature increase stage (S9), third oxidation stage (S10), late natural drying stage. (S11), oxidation ripening step (S12), and mesh mesh sorting and packaging step (S13).

Specifically, the washing step (S1) consists of selecting and washing shellfish.

At this time, the shellfish refers to a shell consisting of any one shell or a combination of two or more shells such as oysters, clams, cockles, abalone, conches, clams, etc. In the present invention, shell powder was manufactured by applying oyster shells. .

Meanwhile, the initial natural drying step (S2) consists of naturally drying the shellfish washed through the washing step (S1) at room temperature.

In this initial natural drying step (S2), the washed shellfish are naturally dried at room temperature, and it is more preferable to naturally dry them so that more than 80% of moisture is removed.

In addition, in the firing preparation step (S3), a plurality of saggars are stacked on the inside of the kiln 1000, and the saggars containing a certain amount of shellfish that have passed the initial natural drying stage are exposed to a plurality of heat and It is done through the process of stacking to form a row.

And the first temperature increase step (S4) consists of raising the temperature to 800°C over 10 hours through operation of the kiln 1000.

Removal of impurities such as carbon dioxide (CO ₂ ) and arsenic (As) can be achieved through the first temperature increase step (S4) as described above.

In addition, the primary oxidation step (S5) consists of a process of supplying forced oxygen for 2 hours and simultaneously discharging forced oxygen by the forced blower 200 at 500°C through the operation of the kiln 1000.

And the secondary oxidation step (S6) consists of a process of supplying forced oxygen for 1 hour and simultaneously discharging forced oxygen by the forced blower 200 at 800°C through the operation of the kiln 1000.

In addition, the constant temperature maintenance step (S7) consists of maintaining 800°C for 5 hours through operation of the kiln 1000.

By going through the constant temperature maintenance step (S7) as described above, impurities such as lead (Pb) and cadmium (Cd) can be removed.

And the medium-term natural drying step (S8) consists of a process of naturally cooling to 50° C. inside the kiln (1000).

In addition, the second temperature increase step (S9) consists of a process of increasing the temperature to 800° C. through operation of the kiln 1000.

And the third oxidation step (S10) consists of a process of supplying forced oxygen by the forced blower 200 and simultaneously discharging oxygen at 800° C. for 1 hour through the operation of the kiln 1000.

In addition, the latter natural drying step (S11) consists of closing the forced air outlet valve 300 and allowing it to cool naturally.

In particular, this late natural drying step (S11) is performed by closing the forced air outlet valve 300 and allowing the air to cool naturally, but it is more preferable to cool the air to less than 100°C.

And the oxidation aging step (S12) consists of taking out the shell that has been fired through the late natural drying step (S11), placing it in a prepared bat, and oxidizing and maturing it for 1 day (24 hours).

Finally, in the mesh network sorting and packaging step (S13), the white, odorless natural shell powder generated through the oxidation maturation step (S12) is sieved through a 50-mesh mesh net, and the filtered shell powder is weighed and vacuum-packed. It is done through a process.

In the method of manufacturing water-soluble shell powder using shells that have undergone the above-described process, in particular, the kiln 1000 includes a furnace main body 100, a forced blower 200, and a forced air outlet valve 300.

At this time, the furnace main body 100 has an inner wall structure heated by electricity, a fixed furnace 110 with one side open, and a fixed furnace that is selectively opened while sliding and returning from one side of the fixed furnace 110. It is preferable that it is composed of a flow passage 120 that seals (110).

Here, on the flow path 120, refractory walls (not denoted) are stacked to form a plurality of columns and rows, and shells are accommodated within the refractory walls.

This flow path 120 is assembled with the fixed furnace 110 through a sliding movement, and the internal space where the fireproof wall is laminated is sealed through the assembly of the fixed furnace 110 and the flow path 120.

In addition, the forced blower 200 is disposed on one external side of the furnace main body 100 and forcibly blows the internal air of the furnace main unit 100 to the outside when operated, and at the same time, the forced blowing blows the furnace main unit ( This is to allow external air to flow into the furnace main body 100 through the lower part that communicates with the outside of the furnace 100.

In addition, the forced blower valve 300 is provided on the pipe connecting the forced blower 200 and the furnace main body 100, and sucks the air inside the furnace main body 100 through the operation of the forced blower 200. Or, it is manipulated to selectively open or close to block.

Meanwhile, the oxidation ripening step (S12) and the mesh screen sorting and packaging step (S13) in the method of producing water-soluble shell powder using shells that have undergone the above-described process may be changed depending on the oxidation aging period and the mesh of the mesh net to be sieved. The longer the oxidation aging period, the finer the particles of the shell powder become, so a finer mesh can be applied.

In this way, when the particles of the shell powder become finer, the dissolution efficiency of water-soluble water can be further improved.

For example, the oxidation aging period in the oxidation aging step (S12) may last for 3 days.

In this case, the mesh net in the mesh net sorting and packaging step (S13) is a process in which the white, odorless natural shell powder generated through the oxidation maturation step is sieved through a 200-mesh mesh net, and the filtered shell powder is weighed and vacuum-packed. It is desirable to proceed as a process.

In an embodiment in which the particles of the shell powder are finer, the period for oxidation aging in the oxidation aging step (S12) may last for 5 days.

In this case, the mesh net in the mesh net sorting and packaging step (S13) is sieved through a 500-mesh mesh net for the white, odorless natural shell powder generated through the oxidation aging step (S12), and the filtered shell powder is weighed to a certain amount. It is desirable to proceed with the vacuum packaging process.
