숯은 그 특성상 연소하면서 강한 열을 오랫동안 발산하는 대신 그을음이 없기 때문에, 음식업소 및 야외 등에서 고기 등을 굽는 고체 연료로서 많이 사용되어 왔다.Charcoal has been used as a solid fuel for grilling meat and the like in a restaurant and an outdoor place because there is no soot instead of dissipating strong heat for a long time due to its characteristics.

통상적으로 숯은 그 원료가 되는 목재에 따라 참나무숯, 합성숯, 갈탄숯, 야자숯 등으로 구분되는데, 주로 참나무숯이 널리 이용되어 왔었다. 그러나, 참나무숯은 성형이 어렵고 강도가 약하며, 연소시간이 짧다는 단점이 있다. 또한, 참나무숯을 제조하기 위해서는 자연환경을 훼손하여야 한다는 단점이 있을 뿐만 아니라 그 공급량이 적기 때문에 구하기가 어렵고 비경제적이라는 문제점이 있다.Typically, charcoal is divided into oak charcoal, synthetic charcoal, lignite charcoal, and palm charcoal, depending on the wood used as a raw material, mainly oak charcoal has been widely used. However, oak charcoal has a disadvantage in that it is difficult to form, weak in strength, and short in combustion time. In addition, in order to manufacture oak charcoal not only has a disadvantage that the natural environment must be damaged, but also because the supply is small, there is a problem that it is difficult to obtain and uneconomical.

따라서, 최근에는 성형이 가능하고 연소시간이 길면서도 경제적인 숯을 제공하기 위하여, 톱밥이나 탄화 야자껍질을 이용한 성형숯이 개발되어 사용되고 있다.Therefore, in recent years, in order to provide a charcoal capable of molding and economical while burning time, shaping charcoal using sawdust or carbonized coconut shell has been developed and used.

이러한 예로서, 국내특허 제144698호에는 톱밥 또는 톱밥과 탄화 야자껍질분말을 이용하여 제조한 고체연료 조성물이 개시되어 있다. 상기 고체연료 조성물은 톱밥 또는 탄화 야자껍질 분말인 연료기재 성분에 니트로셀룰로오스, 아세톤, 메탄올, 이소프로필 알콜 등으로 구성된 연소접착제를 혼합하고 이를 소정의 형상으로 성형하여 제조한다.As an example, Korean Patent No. 144698 discloses a solid fuel composition prepared using sawdust or sawdust and carbonized coconut shell powder. The solid fuel composition is prepared by mixing a combustion adhesive composed of nitrocellulose, acetone, methanol, isopropyl alcohol, and the like into a fuel base component, which is a sawdust or carbonized coconut shell powder, and molded into a predetermined shape.

그러나, 이러한 숯은 주재료인 톱밥 또는 톱밥과 야자껍질 분말의 혼합물에 첨가되는 니트로셀룰로오스, 아세톤, 이소프로필 알콜 등과 같은 화학적 연소접착제가 연소과정에서 유해가스를 발생시킨다는 문제점이 있었다.However, such charcoal has a problem that chemical combustion adhesives such as nitrocellulose, acetone, isopropyl alcohol, etc., added to sawdust or a mixture of sawdust and palm husk powder, which are main ingredients, generate harmful gases during combustion.

본 발명은 이와 같은 종래기술의 문제점을 해결하기 위한 것으로, 탄화 야자껍질 분말을 주원료로 하고 여기에 니트로셀룰로오스 및 분말 설탕 등을 첨가하고 압출성형하여 야자숯을 제조함으로써, 강도가 강하고 착화가 용이하면서도 오랫동안 지속적으로 연소되는 우수한 성능을 갖는 야자숯을 제공하는데 그 목적이 있다.The present invention is to solve the problems of the prior art, by using carbonized coconut shell powder as the main raw material and nitrocellulose and powdered sugar, and extrusion molding to produce a palm charcoal, while the strength is strong and easy to complex The purpose is to provide a palm charcoal with excellent performance which is continuously burned for a long time.

또한, 본 발명은 기존에 사용하던 화학물질 대신에 분말 설탕을 사용함으로써 유해가스를 발산하지 않고 냄새가 나지 않아 음식점 등에서도 불쾌감을 느끼지 않고 편리하게 사용할 수 있는 환경친화적인 숯을 제공하는데 그 목적이 있다.In addition, the present invention is to provide an environmentally friendly charcoal that can be conveniently used without discomfort in restaurants, etc. because it does not emit harmful gas and smell by using powdered sugar instead of conventional chemicals have.

이와 같은 본 발명의 목적을 달성하기 위하여, 본 발명에 따른 야자숯은 (a) 탄화 야자껍질 분말 50~65 중량%; 및 (b) 니트로셀룰로오스, 메탄올 및 분말설탕으로 이루어지는 연소접착제 35~50 중량%를 포함하고, 상기 연소접착제는 연소접착제의 중량기준으로 니트로셀룰로오스 15~35 중량%, 메탄올 60~70 중량%, 및 분말 설탕 5~15 중량%로 이루어지는 것을 특징으로 한다.In order to achieve the object of the present invention, palm charcoal according to the present invention (a) 50 to 65% by weight of carbonized coconut shell powder; And (b) 35 to 50 wt% of a combustion adhesive consisting of nitrocellulose, methanol and powdered sugar, wherein the combustion adhesive is 15 to 35 wt% of nitrocellulose, 60 to 70 wt% of methanol, and It is characterized by consisting of 5 to 15% by weight of powdered sugar.

또한, 본 발명에 따른 야자숯 제조방법은 10~35 메쉬 크기의 탄화 야자껍질 분말을 건조기에 넣어 건조시키는 단계와, 니트로셀룰로오스에 메탄올을 배합하여 교반하는 단계와, 상기 건조된 탄화 야자껍질 분말에 상기 니트로셀룰로오스와 메탄올의 혼합물을 배합하고, 여기에 분말 설탕을 넣고 교반하는 단계, 및 상기 혼합물을 소정의 형상으로 압출성형하는 단계를 포함하는 것을 특징으로 한다.In addition, the method for producing palm charcoal according to the present invention comprises the steps of drying the carbonized coconut shell powder having a size of 10 ~ 35 mesh in a dryer, mixing and stirring methanol to nitrocellulose, and the dried carbonized coconut shell powder Mixing the mixture of nitrocellulose and methanol, it is characterized in that it comprises the step of adding powdered sugar and stirring, and extruding the mixture into a predetermined shape.

본 발명에 따른 야자숯은 탄화 야자껍질 분말 50~65 중량%에 연소접착제 성분 35~50 중량%를 함유하는 것을 특징으로 한다.Palm charcoal according to the present invention is characterized in that it contains 35 to 50% by weight of the combustion adhesive component in 50 to 65% by weight of the carbonized coconut shell powder.

탄화 야자껍질 분말은 본 발명에 따른 숯 조성물의 주원료로서, 폐기되는 야자열매껍질을 태워서 만든 분말이며 잘 건조된 것을 사용한다. 상기 탄화 야자껍질 분말은 연료기재로서 기능을 하며, 연소시에 매연을 발생시키지 않는 효능이 있다. 상기 탄화 야자껍질 분말의 입자 크기는 약 10~35 메쉬 범위로서 입자가 고른 것을 사용하는 것이 바람직하다.Carbonized coconut shell powder is a main material of the charcoal composition according to the present invention, which is a powder made by burning coconut shells discarded and used well dried. The carbonized coconut shell powder functions as a fuel substrate and has an effect of not generating soot during combustion. The particle size of the carbonized coconut shell powder is preferably in the range of about 10 to 35 mesh to use even particles.

상기 탄화 야자껍질 분말에 첨가되는 연소접착제의 경우, 연소접착제의 중량 기준으로 니트로셀룰로오스 15~35 중량%, 메탄올 60~70 중량%, 및 분말설탕 5~15 중량%로 이루어진다. 상기 연소접착제는 점성을 갖고, 제조된 숯이 용이하게 착화력을 부여하고, 부서지지 않도록 접착력을 주어 강도를 유지시키는 역할을 한다.In the case of the combustion adhesive added to the carbonized coconut shell powder, 15 to 35% by weight of nitrocellulose, 60 to 70% by weight of methanol, and 5 to 15% by weight of powdered sugar, based on the weight of the combustion adhesive. The combustion adhesive has a viscosity, serves to maintain the strength by providing the adhesive strength so that the prepared charcoal is easily ignited, and not broken.

좀 더 상세히 설명하면, 니트로셀룰로오스는 제조된 숯이 접착성을 갖도록 하고 착화를 용이하게 하는 한편 오랫동안 숯이 오랫동안 연소할 수 있도록 하는 기능을 한다. 따라서, 니트로셀룰로오스를 첨가하는 양을 조절함으로써 연소 시간을 조절할 수 있다. 상기 니트로셀룰로오스를 너무 많이 첨가하면 제조공정에서 성형이 어려워지고 제조원가를 상승시키게 되며, 반대로 너무 적게 첨가하게 되면 불완전 연소를 일으켜 연기를 발생시킬 우려가 있다. 따라서, 본 발명에서는 연소 접찹제의 중량 기준으로 니트로셀룰로오스를 15~35 중량%로 한정하였다.In more detail, nitrocellulose serves to make the charcoal adhesive and to facilitate the complexation while allowing the charcoal to burn for a long time. Therefore, the combustion time can be adjusted by adjusting the amount of nitrocellulose added. If the nitrocellulose is added too much, the molding becomes difficult in the manufacturing process and the manufacturing cost is increased. On the contrary, the addition of too little nitrocellulose may cause incomplete combustion and generate smoke. Therefore, in the present invention, the nitrocellulose was limited to 15 to 35% by weight based on the weight of the combustion adhesive.

또한, 메탄올은 상기 니트로셀룰로오스를 용해시키기 위하여 첨가되며, 착화력을 강화시키는 역할을 한다. 상기 메탄올의 사용량은 연소접찹제의 중량 기준으로 60-70 중량% 범위가 바람직하다.In addition, methanol is added to dissolve the nitrocellulose, and serves to enhance the ignition power. The amount of the methanol is preferably in the range of 60-70% by weight based on the weight of the combustion adhesive.

한편, 분말설탕은 숯의 접착력을 강화시켜 연소시에 분진이 발생하는 것을 방지함과 동시에 제조 공정시에 점착력을 유지시켜 성형이 서서히 원활하게 진행될 수 있도록 하는 역할을 한다. 상기 분말설탕은 연소접찹제의 중량 기준으로 5~15 중량%로 사용되며, 너무 적게 첨가하면 접착력을 떨어뜨려 제조 공정에서 성형시에 문제점이 발생할 수 있으며, 연소시에는 숯으로부터 분진이 발생시킬 우려가 있다. 반대로 너무 많이 첨가하게 되면 제조 원가를 상승시키게 된다.On the other hand, powdered sugar serves to enhance the adhesion of the charcoal to prevent dust from occurring during combustion and at the same time to maintain the adhesive force during the manufacturing process so that the molding can proceed smoothly. The powdered sugar is used in 5 to 15% by weight based on the weight of the combustion adhesive, if too little added to reduce the adhesive force may cause problems during molding in the manufacturing process, dust may be generated from the charcoal during combustion There is. Conversely, too much addition will increase manufacturing costs.

한편, 본 발명은 먼저 10~35 메쉬 크기의 탄화 야자껍질 분말을 건조기에 넣어 건조시킨다. 이 때, 분말에 함유된 수분의 함량을 10% 이하가 되도록 하는 건조시키는 것이 바람직하다.On the other hand, the present invention first to dry the carbonized coconut shell powder of 10 ~ 35 mesh size in a dryer. At this time, it is preferable to dry so that the content of water contained in the powder may be 10% or less.

그 다음, 상기 단계와는 별도로 니트로셀룰로오스에 메탄올을 교반 하에서 혼합한다. 상기 건조된 탄화 야자껍질 분말에 상기 니트로셀룰로오스와 메탄올의 혼합물을 배합한 후에, 분말 설탕을 추가적으로 투입하고 교반한다. 이와 같이 교반하는 공정은 교반기에서 약 150~300 rpm 속도로 회전시켜 약 3분 정도 교반하는것이 바람직하다.Then, methanol is mixed with nitrocellulose separately under stirring. After blending the mixture of nitrocellulose and methanol to the dried carbonized coconut shell powder, powdered sugar is further added and stirred. In this way, the stirring step is preferably about 3 minutes by rotating at a speed of about 150 ~ 300 rpm in the stirrer.

상기와 같이 얻어진 혼합물은 통상적인 성형기를 이용하여 소정의 형상으로 압출 성형하며, 다양한 형상으로 제조할 수 있다.The mixture obtained as described above is extrusion molded into a predetermined shape using a conventional molding machine, and can be produced in various shapes.
