Description
본 발명은 폐가죽류 즉, 새이빙(shaving)설, 갓도리물 또는 수구레등을 원료로 하여 이로 부터 수용성 단백질과 황산칼슘을 얻는 방법에 관한 것이다.The present invention relates to a method for obtaining water-soluble protein and calcium sulfate from waste hides, namely, shaving, shawl, or ragure.
더욱 구체적으로는, 제혁공정 및 갓도리공정에서 발생되는 폐기물 즉, 폐가죽류중에 투입 또는 함유되어있는 중금속류 예를들면 알루미늄 염류, 중크롬산염류, 질코늄염류등과 불순물인 불포화지방산, 합성유제및 불용물질등을 제거하여 수용성 단백질과 황산칼슘을 얻는 방법이다.More specifically, wastes generated in the tanning and shading processes, that is, heavy metals, such as aluminum salts, dichromates, zirconium salts, and the like, contained in waste leather and impurities, and unsaturated fatty acids, synthetic emulsions, and insoluble substances It is a method of obtaining a water-soluble protein and calcium sulfate by removing the back.
본 발명을 그 공정별에 따라 구체적으로 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail by the process.
[원료선별공정]Raw material selection process
확포한 원료중 순수한 페가죽류가 아닌 쓰레기 및 잡물질을 제거하고 세척한다.Remove and clean garbage and miscellaneous materials that are not pure hides among the expanded raw materials.
[용해공정][Dissolution Process]
선별공정이 끝난 원료를 산도(PH)를 중성으로 조정한 다음 용해조에 투입하고 증기를 가하여 고상의 원료를 용액상태로 용해시킨다.After the sorting process, the pH is adjusted to neutral, and then it is added to the dissolution tank and steam is added to dissolve the solid material in solution.
[반응공정][Reaction Process]
전기 공정에서 용해된 원료를 반응조에 옮긴 다음 산화칼슘 또는 수산화칼슘을 투입하여 온도를 60℃-80℃유지시키고 반응이 끝날때까지 교반하면서 반응시킨다. 이때 원료에 따라 차이가 있지만 반응시간은 2-8시간 정도가 소요된다.After dissolving the raw material in the electric process in the reaction tank, calcium oxide or calcium hydroxide was added to maintain the temperature of 60 ℃-80 ℃ and reacted with stirring until the reaction is completed. At this time, depending on the raw materials, the reaction time takes about 2-8 hours.
[분리공정][Separation process]
반응이 완료된 원료의 온도를 서서히 강하시키면서 분리정체시킨후 원심분리기를 사용하여 순수용액과 찌꺼기를 분리한다.After the reaction is completed, the mixture is stagnated while gradually decreasing the temperature of the raw material, and the pure solution and the residue are separated using a centrifuge.
이때 찌꺼기인 고형분은 건조로에서 건조시킨후 비료로 사용하게 된다.At this time, the solid matter is dried in a drying furnace and used as a fertilizer.
[중화공정][Neutralization Process]
분리된 순수용액은 알카리용액으로서 여기에 황산을 가하여 중화시킨다. 이때 중화가 완료되면 백색의 침전이 형성된다. 백색침전은 PH 5-7에서 가장 활발해진다.The separated pure solution is an alkaline solution and neutralized by adding sulfuric acid thereto. At this time, when neutralization is completed, a white precipitate is formed. White precipitates are most active at pH 5-7.
[여과공정][Filtration process]
중화가 완료된 용액은 마이크로필터를 통과시켜 황산칼슘과 수용성 푸로테인을 분리포집한다. 이때 여과기에 남은 미백색의 분말이 황산칼슘이고 필터를 통과한 미황색의 용액이 수용성푸로테인이다.The neutralized solution is passed through a microfilter to separate and collect calcium sulfate and water soluble lutein. At this time, the light white powder remaining in the filter is calcium sulfate, and the light yellow solution passing through the filter is water soluble lutein.
[건조증발공정]Dry evaporation process
분리포집된 황산칼슘은 건조기에서 건조시키고 수용성 푸로테인용액은 증발기에서 증발시켜 적당한 수분도로 유지시킨다.The separated calcium sulfate is dried in a drier and the aqueous lutein solution is evaporated in an evaporator to maintain the proper moisture.
이상에서 기술한 내용이 본 발명을 완성시키는 전공정이라할 수 있으며 본공정에서 중요한 공정은 반응공정과 중화공정이라 할수 있다. 왜냐하면 공정별로 성분을 분석한 결과 반응공정을 거친후 분리공정에서 찌꺼기와 용액을 분리하면 분리된 용액에는 중금속류가 거의 검출되지 않는다. 이는 산화칼슘과 수산화칼슘이 투입되는 반응공정에서 용액의 PH가 11정도로 유지되면 중금속류가 응집되어 분리공정에서 제거되는 찌꺼기와 함께 제거되는 것으로 판단된다. 중화공정에서는 반응공정에서 투입된 산화칼슘이나 수산화칼슘에 의하여 알카리성 용액으로 유지하여 오다가 중화공정에서 황산을 첨가하므로서 산화칼슘 또는 수산화칼슘과 반응하여 황산칼슘이 생성되어 여과하므로서 푸로테인을 얻을 수 있는 것이다.The contents described above may be referred to as a preprocess to complete the present invention, and important processes in the present process may be referred to as a reaction process and a neutralization process. Because, after analyzing the components by process, the heavy metals are hardly detected in the separated solution if the residue and the solution are separated in the separation process after the reaction process. When the pH of the solution is maintained at about 11 in the reaction process in which calcium oxide and calcium hydroxide are added, it is determined that heavy metals are coagulated and removed together with the residue removed in the separation process. In the neutralization step, the alkaline solution is maintained by calcium oxide or calcium hydroxide introduced in the reaction step, and sulfuric acid is added in the neutralization step to react with calcium oxide or calcium hydroxide to produce calcium sulfate, which is then filtered to obtain protein.
이상의 방법에서 얻어진 황산칼슘은 조단백 20%이상, 황산칼슘이 60%이상이고 수분함량이 18%이하이며 수용성 푸로테인에는 수용성 푸로테인이 50%이상이고 조성분으로 일부 아미노산이 함유되어 있다. 또, 용도로서 황산칼슘은 비료, 사료등의 단백질 및 칼슘강화제등의 용도로 사용할 수 있고 수용성푸로테인은 화장품산업, 공업용 저분자 제과친산업, 사료등 다양한 용도로 사용되어질 수 있다.The calcium sulfate obtained by the above method is 20% or more crude protein, 60% or more calcium sulfate, 18% or less water, and the water-soluble furotene is 50% or more water-soluble lutein and contains some amino acid as a component. In addition, calcium sulfate can be used as a fertilizer, a protein such as feed, calcium fortification, and the like, and water-soluble protein can be used for various purposes such as cosmetics, industrial low molecular confectionery, and food.
더욱이, 본 발명에 의한 폐가죽처리방법은 근간 극심해지고 있는 공해문제를 해소시키는 방법이라 할 수있다. 그 이유로 폐가죽류는 제혁공정중에서 중금속으로 오염된 치명적인 공해유발 물질이라 할 수 있는 바 우선 폐가죽류는 유기물질로서 폐수중에서 분해산화되는 산소량이 크으로 생화학적 산소요구량에 영향을 미쳐 수질오염을 야기시키고 특히, 페가죽류는 일반적으로 산성이면서 중금속크롬으로 오염된 상태이므로 화학적산소요구량에 치명적인 영향을 주게되어 수질을 크게 오염시키게 되므로 이와같은 관점에서 볼때 본 발명에 의한 폐가죽처리방법은 국가적인 차원에서 장려해야 할 산업성이 있는 우수한 방법이다.Moreover, the waste leather treatment method according to the present invention can be said to solve the pollution problem that has become severe in recent years. For this reason, waste leather is a fatal pollutant that is contaminated with heavy metals in the tanning process. First of all, waste leather is an organic substance that has a large amount of oxygen that is decomposed and oxidized in waste water, which affects the biochemical oxygen demand and causes water pollution. Particularly, since the pelts are generally acidic and contaminated with heavy metal chromium, they have a fatal effect on chemical oxygen demand and greatly contaminate water quality. Therefore, the method of treating waste leather according to the present invention is encouraged at the national level. It's an excellent way to be industrial.
