이하 본 발명의 실시 예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described.

본 발명에 따른 원료로는 주원료인 옥수수전분과 이 옥수수전분으로 용기를 제조할 때 용기의 형태를 갖추는 필수조건인 결합력(結合力)과 강도(强度) 및 탄력성을 유지시켜주기위한 폴리비닐알콜, 단백질, 고구마전분, 명반, 보습제와 소정량의 물등이 첨가된다.The raw material according to the present invention is a corn starch which is a main raw material and polyvinyl alcohol for maintaining the binding force, strength and elasticity, which is an essential condition in the form of a container when manufacturing a container from the corn starch, Protein, sweet potato starch, alum, moisturizer and a predetermined amount of water are added.

상기 각 원료를 이용하여 용기를 제조하는 단계를 크게 나누어 보면, 폴리비닐알콜과 단백질 및 고구마전분, 명반, 보습제를 혼합물로 제조하는 단계와, 상기 혼합물을 호화(糊化)상태로 만들어 옥수수전분에 넣어 교반하면서 반죽상태로 만드는 단계와, 상기 반죽상태의 혼합물을 압출기로 압출시킨후 압연로울러로 압연시키는 단계와, 금형으로 제품의 형태에 맞게 성형하는 단계와, 상기 제품을 냉각금형으로 냉각성형시켜 응고 및 분리시키는 단계로 나누어지게 되는데, 상기 각 단계별로 이루어지는 것을 상세하게 설명하면 다음과 같다.Dividing the steps of preparing a container with each of the raw materials, preparing a polyvinyl alcohol and protein and sweet potato starch, alum, moisturizing agent as a mixture, and made the mixture into a state of corn starch Putting the mixture into stirring state, extruding the mixture of the dough state with an extruder and rolling it with a rolling roller, forming a mold according to the shape of the product, and cooling the product with a cooling mold. Coagulation and separation are divided into steps, which will be described in detail for each step.

우선 제1공정으로는 겔(Gel)상태의 폴리비닐알콜 1~2%에 점액으로된 단백질 0.5~0.05%을 교반하여 혼합물을 제조하게 되는데, 상기 폴리비닐알콜은 식용가능하고 비교적 점성이 낮은 제품을 사용하며 또한 용기를 제작하였을 때 용기의 형태를 유지시켜주는 접착성(接着性)과 탄력성(彈力性) 및 용해성(溶解性)을 갖고 있어 용기제작시 각종 전분과 명반 및 보습제와의 친화력과 결합력을 증가시키므로 일회용도시락의 성형작업이 용이하고 응고된 후에도 적당한 강도를 유지하게 되어 용기에 어느 정도의 충격력이 가해지게 되도 충격력을 견딜 수 있으며, 또한 내열성이 150℃정도이므로 용기에 뜨거운 물을 부어 사용하게 되도 사용중에는 용기의 외관이 변형되지 않고, 장시간 물이나 흙속에 포함되어 있게 되면 용해되어 부폐하는 성질을 갖고 있는 것이다.First, in the first process, a mixture is prepared by stirring 0.5 to 0.05% of a protein of mucus to 1 to 2% of polyvinyl alcohol in a gel state, and the polyvinyl alcohol is an edible and relatively low viscosity product. It also has adhesiveness, elasticity and solubility that maintain the shape of the container when it is manufactured. As it increases the bonding force, it is easy to mold disposable lunch box and maintains the proper strength even after solidification. It can withstand the impact force even if a certain impact force is applied to the container. Also, since the heat resistance is about 150 ° C, Even if it is used, it does not deform the container during use, and if it is contained in water or soil for a long time, it dissolves and decays. .

그리고 상기 단백질은 폴리비닐알콜에 고구마전분과 명반 및 보습제등을 교반할 때 서로 친화력(親和力)을 갖도록 하는 요소(要素)로 작용한다.In addition, the protein acts as a urea to have affinity with each other when stirring sweet potato starch, alum and a moisturizing agent to polyvinyl alcohol.

제2공정으로는 상기 폴리비닐알콜과 단백질을 혼합한 혼합물에 고구마전분 3~4%, 명반 1~2%, 보습제 1~2%등을 혼합하고 이 혼합물에는 물 1/5~1/10정도로 교반하여 혼합물을 제조하게 되고, 이 혼합물을 80~100℃정도의 온도를 유지하는 물에 넣고 교반하여 호화(糊化)상태로 만드는 제3공정으로 이루어 진다.In the second step, 3 ~ 4% sweet potato starch, 1 ~ 2% alum, 1 ~ 2% moisturizer, etc. are mixed with the mixture of polyvinyl alcohol and protein, and the mixture is water 1/5 ~ 1/10. The mixture is prepared by stirring, and the mixture is put into water maintaining a temperature of about 80 to 100 ° C., followed by a third step of stirring and bringing the mixture into a luxurious state.

상기 고구마전분은 접착력이 강하고 응고된 상태에서는 강도가 우수하여 옥수수전분과 혼합되게 되면 상호 친화력과 탄성 및 강도를 증가시키는 것이고, 명반은 용기의 강도(强度)를 유지시키는 것이다.The sweet potato starch is strong in the adhesive state and solidified state, when mixed with corn starch increases mutual affinity, elasticity and strength, alum is to maintain the strength of the container (强度).

그리고 보습제는 습윤조정제(濕潤調整劑)로서 솔비톨(Sorbitol)을 사용하게 되는데 용기의 수분증발을 억제하여 용기가 경화되는 것을 방지하는 역할을 하게 된다.And the humectant is to use sorbitol (Sorbitol) as a wetting agent (濕潤 調整 劑) serves to prevent the container from hardening by inhibiting the water vaporization of the container.

또한 상기 각종 혼합물을 교반하는 과정에서 5-7g정도의 식용색소를 첨가하여 일회용도시락의 용도와 기호에 적합한 색상으로 제작할 수도 있는 것이다.In addition, 5-7 g of food coloring may be added in the process of stirring the various mixtures to produce a color suitable for the purpose and preference of the disposable lunch box.

제4공정으로는 옥수수전분 90~95%에 상기 제3공정에서 제조된 호화상태의 혼합물을 소량씩 부어가며 반죽상태로 만들게 되며, 상기 반죽상태의 혼합물은 120~130℃의 온도를 유지하는 압출기로 압출시키게 되면 반죽이 차지게 형성되는 제5공정으로 이루어지게 된다.In the fourth process, a small amount of the gelatinous mixture prepared in the third process is poured into 90 to 95% of corn starch, and the dough mixture is made into a dough state. The dough mixture is maintained at a temperature of 120 to 130 ° C. When extruded to the fifth step is made to form a dough.

상기 압출기로 압출된 혼합물을 120~130℃의 온도를 유지하는 압연로울러로 압연(壓延)하는 제6공정으로 이루어지게 되고, 제7공정으로는 제품과 같은 형태를 유지하는 금형을 120~130℃의 온도를 유지한 상태에서 용기를 제작하게 된다.The sixth step of rolling the mixture extruded by the extruder with a rolling roller to maintain a temperature of 120 ~ 130 ℃, the seventh process is a 120 ~ 130 ℃ a mold to maintain the same shape as the product The container is manufactured while maintaining the temperature of.

상기 금형으로 성형된 제품을 제품과 대응하고 -50~-60℃의 온도를 유지하는 냉각금형으로 성형하여 응고시키고 분리시키는 제8공정으로 되는 것이다.The eighth step of forming the product molded in the mold and the product into a cooling mold corresponding to the product and maintaining a temperature of -50 to -60 ℃ to solidify and separate.
