The present invention relates to a method for manufacturing a type of dish detergent using kelp extract and a type 1 dish detergent produced thereby. More specifically, the present invention relates to a method of manufacturing a type of dish detergent using kelp extract. More specifically, the present invention relates to a method of manufacturing a type of dish detergent using kelp extract. More specifically, the present invention relates to a method of manufacturing a type of dish detergent using kelp extract. More specifically, it is made using kelp as the main ingredient, which is non-irritating to the skin, eco-friendly, and has excellent cleaning power. It has excellent safety to the human body and is gentle on the skin. The present invention relates to a method for manufacturing a type 1 dish detergent using kelp extract, which is non-irritating and has excellent cleaning power as well as antibacterial activity due to the synergistic effect of each added composition, and a type 1 dish detergent manufactured thereby.

According to the Ministry of Health and Welfare notification standards (specifications and standards for sanitary products), detergents used to wash vegetables or fruits that can be eaten by humans are classified as type 1, and detergents used to wash food utensils such as food utensils and cooking utensils are classified as type 1. Cleaning agents are classified into two types, and detergents for washing manufacturing and processing equipment such as food manufacturing equipment and processing equipment are classified into three types.

Recently, as chemical products containing environmental hormones that are harmful to the environment and the human body are known to accumulate in the body and cause endocrine disorders, lower immune function, and cause skin diseases such as atopy, the demand for environmentally friendly natural products has increased. It is becoming. In line with this trend, kitchen detergents being released these days use natural ingredients, have low skin irritation, and are biodegradable, emphasizing that they can reduce environmental pollution. However, only a very small amount of natural ingredients are contained among the total ingredients, and the irritation is as high as before. Although it has decreased slightly compared to other products, it is still irritating at a level of more than medium intensity, enough to cause skin problems such as eczema and rashes. It is harmful to the human body as it contains harmful sterilizing substances for antibacterial and sterilizing purposes and toxic substances such as environmental hormones, and is not biodegradable. There were some problems that didn't work out well.

In addition, various kitchen detergents that are released claiming to be eco-friendly are also products that contain various types of surfactants that are harmful to the human body, highly irritating, have low biodegradability, and are environmentally destructive in order to provide superior cleaning power and differentiated functionality. . If these products come into even the slightest contact with the skin during the cleaning process with dish detergent, they can be unbearably irritating to the skin and cause eczema or rashes. Not only that, but some of the ingredients are absorbed into the body through the skin during the washing and cleansing process. There are chronic problems that not only cause endocrine disorders and adversely affect the health of consumers, but also flow into rivers and destroy the environmental ecosystem. There is a need for the development of new products that can fundamentally solve these problems.

Therefore, there is a need to develop a dishwashing detergent that is non-irritating to the skin, is eco-friendly, and is mainly made of ingredients that have excellent cleaning power.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a step flow diagram showing a method for manufacturing a type of dish detergent using kelp extract according to the present invention.

The method for manufacturing a type of dish detergent using kelp extract according to the present invention includes a pretreatment step (S10), an immersion step (S20), a first crushing and separation step (S30), a second crushing and separation system (S40), and a mixing step ( S50), the first ripening and sterilization step (S60), and the second ripening and sterilization step (S70).

1. Preprocessing step (S10)

The pretreatment step (S10) is a step in which the washed kelp from which foreign substances have been removed is passed through a tunnel heater and then passed through a cooling water washing tunnel.

More specifically, the washed kelp from which foreign substances have been removed is passed through a tunnel heater at 90 to 95°C and then passed through a cooling water washing tunnel at 20 to 25°C.

Through this, the washed kelp with foreign substances removed is passed through a high-temperature tunnel heater, which heats the kelp quickly and evenly and sterilizes it at the same time. After heating, it is immediately passed through a cooling water washing tunnel to lower the temperature of the heated kelp and wash it. can be done at the same time.

Here, the kelp is used in a living state that is not salted or heated.

Kelp is an alkaline food containing various minerals and microorganisms, and has excellent cleansing power, removing microorganisms, removing contaminants, providing minerals, and providing gentle cleansing.

2. Immersion step (S20)

The immersion step (S20) is a step of immersing the kelp pretreated in the pretreatment step (S10) in a citric acid and baking soda solution storage tank.

More specifically, the kelp pretreated in the pretreatment step (S10) is immersed in a citric acid and baking soda solution storage tank at 20 to 25 ° C. for 1 to 3 hours.

Through this, effective ingredients are extracted from the kelp pretreated in the pretreatment step (S10) through citric acid and baking soda solution, and along with the cleaning action of citric acid and baking soda solution, effects such as odor removal, precipitation prevention, antibacterial and preservative action, etc. You will have

If the kelp pretreated in the pretreatment step (S10) is immersed in a citric acid and baking soda solution storage tank below 20°C for less than the above time, the effective components of the kelp cannot be sufficiently extracted, and citric acid exceeding 25°C And, if immersed in the baking soda storage tank for more than the above time, the problem of deterioration of the kelp may occur.

Here, the citric acid and baking soda solution is prepared by mixing 100 parts by weight of citric acid with 100 to 200 parts by weight of baking soda and 500 to 1,000 parts by weight of water.

The citric acid and baking soda solutions have powerful cleaning effects as well as odor removal, precipitation prevention, and preservative effects.

As the kelp pretreated in the pretreatment step (S10) is immersed in the citric acid and baking soda solution, the effective ingredients of the kelp are eluted more smoothly, and the strong cleaning action of the citric acid and baking soda solution removes odor, prevents precipitation, antibacterial and Antiseptic effects can also be expected.

3. First crushing and separation step (S30)

The first crushing and separation step (S30) is a step of crushing the kelp liquid immersed in citric acid and baking soda solution in the immersion step (S20) and then separating the first supernatant through a centrifuge.

More specifically, in the immersion step (S20), the kelp liquid immersed in citric acid and baking soda solution is pulverized, and the kelp liquid in the kelp liquid is crushed to a particle size of 0.1 to 0.5 mm, and then crushed at 2,000 to 3,000 RPM. The first supernatant is separated through a high-speed centrifuge.

At this time, in the grinding process, the kelp may be pulverized including citric acid and baking soda solution in which the kelp was immersed in the immersion step (S20).

This, along with the ease of grinding, not only eluted the effective components of the kelp into the citric acid and baking soda solution during the maturation of the kelp in the immersion step (S20), but also provided effective components in the cleaning action of the citric acid and baking soda solution. This is to do so.

4. Second crushing and separation step (S40)

In the second crushing and separation step (S40), the primary supernatant pulverized and separated in the first crushing and separation step (S30) is pulverized through a high-speed fine grinder, and then the second supernatant is separated through a filtering device to produce kelp extract. This is the stage of extracting.

More specifically, the first supernatant pulverized and separated in the first pulverization and separation step (S30) is pulverized through a high-speed fine grinder at a speed of 3,000 to 5,000 RPM, and then the secondary supernatant is filtered through a 250 to 500 mesh filtering device. Separate and extract the kelp extract.

In the first grinding and separation step (S30), higher quality kelp extract can be extracted from the primary supernatant ground and separated through high-speed grinding and fine filter processes.

At this time, citric acid and baking soda solution at 2 to 10°C can be further added during the grinding process.

More specifically, in the grinding process, 50 to 200 parts by weight of citric acid and baking soda solution at 2 to 10 ° C. are further added to 100 parts by weight of the primary supernatant ground and separated in the first grinding and separation step (S30). .

This is to reduce the frictional heat generated during high-speed grinding and prevent the effective components of the first supernatant ground and separated in the first grinding and separation step (S30) from being destroyed.

5. Mixing step (S50)

The mixing step (S50) is a step of mixing vegetable glycerin, levulinic acid, tea tree oil, green tea extract, and cucumber extract with the kelp extract pulverized, separated, and extracted in the second crushing and separation step (S40).

More specifically, based on 100 parts by weight of the kelp extract pulverized and separated and extracted in the second grinding and separation step (S40), 5 to 15 parts by weight of vegetable glycerin, 5 to 10 parts by weight of levulinic acid, and tea tree oil. Mix 1 to 3 parts by weight, 50 to 100 parts by weight of green tea extract, and 50 to 100 parts by weight of cucumber extract at a speed of 500 to 700 RPM while maintaining 20 to 25 degrees Celsius for 12 to 48 hours.
