Description

표고버섯 폐톱밥을 이용한 우드펠릿 제조방법{WOOD PELLET MANUFACTURING METHOD USING THE SHIITAKE CULTIVATION SAWDUST WASTE}TECHNICAL FIELD [0001] The present invention relates to a wood pellet manufacturing method using wood shavings,

본 발명은, 표고버섯 등을 재배한 후 폐기되는 톱밥 부산물을 이용하여 우드펠릿을 제조하는 방법 및 그 우드펠릿에 대한 것으로, 폐자료를 이용하여 환경을 보호하며 우드펠릿을 연소용으로 활용하여 친환경 신재생에너지연료를 제공하는 방법을 제공한다.The present invention relates to a method for producing wood pellets using sawdust by-products after cultivation of shiitake mushroom and the like, and a wood pellet for protecting the environment by using waste materials and using wood pellets for combustion, And provides a way to provide renewable energy fuels.

펠릿은 조그만 원기둥 모양의 압축된 형태의 제제를 의미한다. 우드펠릿은, 일반적으로 산림 부산물 또는 목재를 가공하며 발생하는 잉여 목재조각을 이용하여 제조한다. 또한, 펠릿 형태는 저장성과 운반성이 용이하여 연료로 사용하는 우드펠릿 뿐만 아니라 펠릿형 동물 사료의 제조에도 널리 사용되는 유용한 기술이다. The pellet refers to a compressed form of a small cylindrical shape. Wood pellets are produced using a piece of surplus wood, usually produced by processing wood by-products or wood. In addition, the pellet form is a useful technique widely used for the production of pelletized animal feed as well as wood pellets used as a fuel due to its easy storage and transportability.

우드펠릿은 석유자원과는 다르게 조림(造林)과정에서 상시 발생하여 순환성이 매우 뛰어나면서도 화석연료에 비하여 오염물질의 발생량도 상대적으로 낮은 자원이다. 우드펠릿은, 최근까지도 농촌지역 및 도시의 일반 가정집에서도 사용되고 있으며, 최근에는 펜션, 별장 등에서 난방 및 분위기 연출의 목적으로 많이 활용되는 우수한 연료이다. 특히 농촌지역에서는 겨울철 작물을 재배할 때 에너지비용 부담을 줄일 수 있다는 장점도 있어서, 최근 지방자치단체에서도 설치 시설비를 지원하고 있는 등 활용도가 높은 대체에너지 중 하나이다. 그러나, 현재 국내에서는 충분한 수량의 우드펠릿이 생산되지 못하여 수요량의 70% 정도인 200,000톤 수입하고 있으며 수입금액 또는 3000만불이 넘어서고 있다.Unlike petroleum resources, wood pellets are constantly generated during the afforestation process and have excellent circulation, while the amount of pollutants generated is relatively low compared to fossil fuels. Until recently, wood pellets have been used in ordinary households in rural areas and cities. Recently, they are excellent fuels that are widely used for heating and ambience production in pensions and villas. Especially in rural areas, it has the advantage of reducing the energy cost burden when growing winter crops, and it is one of the highly utilized alternative energy such as supporting the installation cost in local governments. However, at present, sufficient quantity of wood pellets can not be produced in Korea, so 200,000 tons of 70% of the demand is imported, and the import amount is over 30 million dollars.

한편, 느타리버섯, 팽이버섯을 재배하고 발생하는 폐배지는 가축의 조사료와 퇴비로 사용이 가능하여 상업적으로 사용되고 있으나, 표고버섯 톱밥 폐배지는 대부분이 목질성분으로서 동물의 조사료로 사용하기 어렵고 퇴비로 사용하기 위해서는 퇴비화 과정이 길고 비용이 많이 들어 퇴비로도 활용도가 낮다. 그러나, 표고버섯은 그 수요가 해마다 20% 수준으로 꾸준하게 증가하고 있다. 또한, 표고버섯의 재배방식 또한 원목재배에서 톱밥재배 방식으로 전환되고 있다. 이러한 현실에서, 표고버섯의 톱밥 폐배지를 해마다 증가하고 있으나 이를 적절하게 이용하는 방법이 거의 전무하다는 문제점이 있다.On the other hand, the waste medium that is cultivated in the oyster mushroom and top mushroom is commercially used because it can be used as forage and compost for livestock. However, most of the waste medium of mushroom sawdust is hard to use as animal forage as compost The composting process is long and costly to use, and the utilization rate is low as compost. However, the demand for shiitake mushrooms is steadily increasing to 20% per year. In addition, the cultivation method of shiitake mushroom has also been changed from woody to sawdust cultivation. In such a situation, the sawdust waste medium of shiitake mushrooms is increasing year by year, but there is a problem that there is almost no method to use it properly.

이하, 본 발명을 보다 상세하게 설명한다Hereinafter, the present invention will be described in more detail

본 발명의 일 실시예에 따른 우드펠릿의 제조방법은, 폐톱밥으로부터 이물질을 제거하고 분쇄하는 전처리단계; 상기 분쇄된 폐톱밥을 건조하는 건조단계; 및 상기 건조된 폐톱밥과 첨가제를 포함하는 조성물을 혼합하고 성형하여 우드펠릿을 제조하는 혼합성형단계;를 포함한다. A method of manufacturing a wood pellet according to an embodiment of the present invention includes: a pretreatment step of removing foreign matters from pulverized sawdust and pulverizing the waste pellets; Drying the pulverized waste wood pulp; And a mixed molding step of mixing and molding the dried waste wood pulp with a composition containing the additive to produce wood pellets.

상기 폐톱밥로는 표고버섯 폐톱밥 배지가 사용될 수 있으며, 구체적으로 표고버섯배지 제조과정 중에 사용한 비닐과 같은 이물질을 제거하고 분쇄한 것을 사용할 수 있다. 이때 분쇄는, 예를 들어 3 mm 이하의 크기로 상기 폐톱밥배지를 분쇄하여 사용될 수 있으나, 분쇄의 크기는 제조하고자 하는 우드펠릿의 크기, 건조의 정도 등을 고려해서 적절하게 조절할 수 있다.As the waste sawdust, shiitake pulp sawdust medium may be used. Specifically, shredded rice can be used after removal of impurities such as vinyl used during the production of shiitake medium. At this time, the pulverization can be used by pulverizing the waste wood pulp with a size of, for example, 3 mm or less, but the size of pulverization can be appropriately adjusted in consideration of the size of the wood pellet to be manufactured, the degree of drying, and the like.

상기 분쇄된 폐톱밥은 수분이 20% 이하가 되도록 건조하는 것이 좋다. 버섯 재배에 활용된 폐톱밥은 버섯 재배 중에 사용한 수분을 상당량 머금고 있으며, 이를 펠릿제조에 적절한 수준으로 건조시키는 것이 좋다. 예를 들어, 분쇄된 폐톱밥 내의 수분이 20 중량% 이하로 건조시키는 것이 바람직하다.The pulverized waste sawdust is preferably dried so that the water content is 20% or less. The waste sawdust used for cultivation of mushrooms has a considerable amount of water used during mushroom cultivation and it is recommended to dry it to a level suitable for producing pellets. For example, it is preferable to dry the pulverized waste wood at a moisture content of 20 wt% or less.

건조의 방법에는 특별한 제한이 없으며, 예를 들어 100 ℃ 내지 120 ℃의 건조로에서 1 내지 2 시간 건조시키거나, 햇볕과 바람이 잘 통하는 개방된 장소에서 약 1일 내지 3일 동안 건조시킬 수 있다.There is no particular limitation on the drying method, and it may be dried for 1 to 2 hours, for example, in a drying furnace at a temperature of 100 to 120 DEG C, or may be dried for about 1 to 3 days in an open place where sunlight and wind are in good condition.

상기 혼합형성단계는 우드펠릿 제조용 조성물을 혼합하고 성형하여 우드펠릿으로 제조하는 과정이다. 상기 우드펠릿 제조용 조성물은, 상기 건조된 폐톱밥 100 중량부와 첨가제 5 내지 30 중량부를 포함할 수 있으며, 여기서 첨가제는 숯, 활성탄 및 이들의 조합으로 이루어진 군에서 선택된 어느 하나이다.The mixing-forming step is a step of mixing and molding the composition for making wood pellets into wood pellets. The composition for preparing wood pellets may comprise 100 parts by weight of the dried waste wood saw and 5 to 30 parts by weight of an additive, wherein the additive is any one selected from the group consisting of charcoal, activated carbon, and combinations thereof.

표고버섯을 재배하고 폐기되는 폐톱밥은 일반 목재로 제조하는 우드펠릿과는 다르게 곰팡이 발생 가능성이 상당히 높다. 이에, 톱밥을 충분하게 건조시켜서 곰팡이의 발생을 방지하는 과정이 필요하나, 습한 장소에 보관할 경우에는 충분하게 건조하여 제조한 표고버섯 폐배지로 만든 우드펠릿에도 곰팡이의 발생 가능성이 있다. 이에 첨가제로, 숯 또는 활성탄을 첨가하여 제조된 펠릿의 곰팡이 발생 가능성을 현격하게 줄일 수 있다. 또한, 상기 우드펠릿에 포함된 숯 또는 활성탄과 같은 첨가제는 상기 첨가제를 첨가하지 않고 폐톱밥만으로 제조한 우드펠릿과 비교하여 연소시 열량이 높아진다는 장점도 있다.The waste sawdust cultivated with shiitake mushrooms is much more likely to develop fungi than wood pellets made from ordinary wood. Therefore, it is necessary to sufficiently dry the sawdust to prevent the occurrence of fungi. However, when stored in a humid place, there is a possibility of causing mold in the wood pellet made of the shiitake waste medium prepared by drying sufficiently. As a result, it is possible to remarkably reduce mold generation of pellets produced by adding charcoal or activated carbon as an additive. In addition, additives such as charcoal or activated carbon contained in the wood pellets have an advantage in that the amount of heat during combustion is higher than that of wood pellets produced only from pulverized sawdust without adding the additive.

상기 첨가제는 건조 폐톱밥 100 중량부를 기준으로 5 내지 30 중량부로 사용될 수 있고, 바람직하게 5 내지 10 중량부로 사용될 수 있다. 상기 첨가제를 5 중량부 미만으로 사용하는 경우에는 첨가제 추가에도 불구하고 제조된 우드펠릿에 곰팡이가 쉽게 발생될 수 있고, 30 중량부를 초과하는 경우 불필요하게 숯 또는 활성탄을 낭비되거나 생산단가가 높아질 수 있다. 특히, 건조 폐톱밥 100 중량부를 기준으로 5 내지 10 중량부로 숯이나 활성탄과 같은 첨가제를 사용하는 것이 유리한데, 폐자재를 활용한 우드펠릿의 경제성을 유지하면서 곰팡이 발생도 억제할 수 있다.The additive may be used in an amount of 5 to 30 parts by weight, preferably 5 to 10 parts by weight, based on 100 parts by weight of dry waste sawdust. If the additive is used in an amount of less than 5 parts by weight, molds can easily be produced in the produced wood pellets despite the addition of additives, and if the additive is added in an amount exceeding 30 parts by weight, charcoal or activated carbon may be unnecessarily wasted or the production cost may be increased . Particularly, it is advantageous to use additives such as charcoal and activated carbon with 5 to 10 parts by weight based on 100 parts by weight of dried waste sawdust, and mold generation can be suppressed while maintaining economical efficiency of wood pellets using waste materials.

상기 혼합된 우드펠릿 제조용 조성물은 통상 사용되는 우드펠릿 제조 방법을 이용하여 우드펠릿으로 제조될 수 있다. 예를 들어, 펠릿제조기계를 이용하여 750 내지 1,000 kg/cm3 압력으로 압출하여 작은 원통 형태로 우드펠릿을 성형할 수 있으며, 필요에 따라 제조된 우드펠릿의 크기나 중량은 조절될 수 있다.The composition for making the mixed wood pellets can be made into wood pellets using a commonly used wood pellet manufacturing method. For example, the pellets can be molded into a small cylindrical shape by extrusion at a pressure of 750 to 1,000 kg / cm < 3 > using a pelletizing machine, and the size or weight of the wood pellets can be adjusted as needed.

상기 혼합성형단계에서 제조된 우드펠릿은 추가적인 건조단계를 더 거칠 수 있다. 버섯 폐배지의 특성상 수분함량이 많고 곰팡이가 생기기 쉬우므로, 보관성을 더 향상시키기 위해서 상기 우드펠릿은 제조 후 수분 함량이 10 중량% 이하, 0.01 내지 10 중량%, 더 좋게는 0.01 내지 5 중량%가 되도록 건조시킬 수 있다.The wood pellets produced in the mixing and molding step may be further subjected to an additional drying step. In order to further improve storage properties, the wood pellets preferably have a moisture content of not more than 10% by weight, preferably 0.01 to 10% by weight, more preferably 0.01 to 5% by weight, after production, since the mushroom waste medium has a high moisture content and is susceptible to mold. . ≪ / RTI >

본 발명에서 우드펠릿의 원료로 이용한 폐톱밥은 버섯을 재배하는 배지로 사용된 후 폐기되는 폐배지로, 그 동안 목질 성분이 많아서 활용도가 낮았던 표고버섯 톱밥 폐배지를 활용하여 우드펠릿을 제조할 수 있다.In the present invention, pulpwood used as a raw material for wood pellets is a waste medium which is used as a medium for growing mushrooms and then is discarded. Wood pellets can be produced using a mushroom sawdust waste medium, have.

본 발명은, 활용되지 못하고 버려지는 폐자재를 사용한다는 점에서도 환경적으로 우수하지만, 목질이 연화된 재료를 활용한다는 점에서도 유리하다. 일반적인 표고버섯 배지 제조 과정에서 표고버섯 종균 접종 전에 autoclave로 1차 멸균과정을 통해 열처리가 이루어지고, 배양 및 재개기간인 약 6개월 동안 버섯 균사에 의하여 배지 내의 목질 성분(셀룰로오스, 리그닌 등)이 천천히 분해된다. 때문에, 폐배지는 건조 후 촉감이 푸석할 정도로 목질이 상당히 연화된 상태이다. 따라서, 제조된 우드펠릿 내에 연소시 냄새를 유발시키는 기타 오염물질의 유입이 현저하게 적고, 분쇄 등이 용이하며, 연소 효율도 높게 나타날 수 있다. The present invention is also advantageous in that it utilizes a wood-softened material although it is environmentally excellent in that it uses abandoned materials which are not utilized and discarded. During the production of general mushroom culture medium, the mushroom hyphae were heat-treated by autoclave through a primary sterilization process before the inoculation of the mushroom cultivar. During the incubation and resuming period of about 6 months, the mushroom hyphae slowly transferred the woody components (cellulose, lignin, etc.) Decomposed. Therefore, the waste medium is in a state in which the woody matter is considerably softened to such an extent that after the drying, the skin becomes soft. Accordingly, the produced wood pellets are remarkably less influx of other contaminants that cause the odor during combustion, can be easily pulverized, and the combustion efficiency can be high.

나아가, 상기 폐배지에 숯 또는 활성탄을 첨가하여 곰팡이의 발생 정도도 낮추고, 동시에 연소 시에 발생하는 잡냄새나 미량 발생하는 유해물질도 활성탄(숯)이 흡착하여, 우드펠릿의 연소시 발생하는 냄새 유발물질과 유해물질의 배출을 현격히 줄일 수 있다. 또한, 숯(활성탄)은 연소시 발생 열량을 증가시켜 연소용 우드펠릿의 열 효율성을 더 높일 수 있다.Further, charcoal or activated carbon is added to the waste medium to lower the degree of occurrence of fungi. At the same time, odorous or harmful substances generated during combustion are adsorbed by activated charcoal (charcoal), and odor generated during burning of wood pellets The emission of the inducing substances and the harmful substances can be remarkably reduced. In addition, charcoal (activated carbon) can increase the heat generated during combustion and further increase the thermal efficiency of the combustion wood pellet.

본 발명의 다른 일 실시예에 따른 우드펠릿은, 버섯재배용 톱밥의 폐톱밥 100 중량부; 및 숯, 활성탄 및 이들의 조합으로 이루어진 군에서 선택된 어느 하나의 첨가제 5 내지 30 중량부;를 포함한다. 상기 폐톱밥은 표고버섯 재배용 참나무 톱밥의 폐배지일 수 있고, 톱밥배지 제조과정과 버섯재배 과정에서 톱밥배지 내의 목질 성분이 분해되어, 폐톱밥 내의 셀룰로오스와 리그닌의 함량이 버섯재배 전 톱밥보다 낮은 것일 수 있다.A wood pellet according to another embodiment of the present invention comprises: 100 parts by weight of waste sawdust of sawdust for mushroom cultivation; And 5 to 30 parts by weight of any one selected from the group consisting of charcoal, activated carbon, and combinations thereof. The waste sawdust may be a waste medium of oak sawdust for shiitake mushroom cultivation, and the woody component in the sawdust medium is decomposed in the sawdust medium production process and the mushroom cultivation process, and the content of cellulose and lignin in the pulpwood sawdust is lower than that of sawdust .

위에서 상술한 바와 같이, 본 발명에 따른 표고버섯 톱밥 폐배지를 이용한 우드펠릿은 폐기물로 인한 주변 환경을 보호하며 우드펠릿으로 제조하여 대체에너지로 사용할 수 있다. 또, 숯 또는 활성탄을 첨가하여 연소시 열량이 더 높으며, 난방용뿐만 아니라 냄새가 없는 참나무 원료로서 조리용 연료로도 활용할 수 있다. 나아가, 본 발명에 따른 우드펠릿은 폐기되는 농업 부산물을 현장에서 제조하고 현장에서 에너지로 활용함으로서 작물의 재배에도 생산원가를 낮출 수 있어 수입 농산물과의 경쟁력에서도 유용하며, 특히 겨울철 시설재배에는 연소 시 발생하는 소량의 이산화탄소는 광합성 작용을 촉진시켜 일조량이 적은 작물의 생육에도 효과가 있다.As described above, the wood pellet using the shiitake mushroom sawdust waste medium according to the present invention protects the environment caused by waste, and can be used as alternative energy by being made into wood pellets. In addition, charcoal or activated carbon is added and the amount of heat is higher during combustion, and it can be used as cooking fuel as a raw material for oak which has no odor as well as for heating. In addition, the wood pellets according to the present invention are useful in competitiveness with imported agricultural products because they can reduce the production cost even in the cultivation of crops by producing disused agricultural by-products on site and using them as energy in the field. Especially, The small amount of carbon dioxide that is generated promotes photosynthesis, which is effective for the growth of crops with a small amount of sunlight.

우드펠릿은 산림을 조림하거나 목재를 가공하고 나오는 부산물을 이용하여 제조하는 에너지 자원으로서, 일반적으로 우드펠릿의 제조장소는 소비가 발생하는 장소가 아닌 원재료를 손쉽게 얻을 수 있는 산림 또는 목재 가공공장 근처이다. 그러나, 우드펠릿은 원료로서 경제성이 낮은 편이고 제조 장소로부터 수요지역으로까지 운송비용이 높아 가격이 비싸다는 문제점이 있었다.Wood pellets are energy resources that are produced by using forests or by-products produced by processing wood, and generally wood pellets are produced in a forest or wood processing plant where raw materials can be easily obtained, not where consumption occurs . However, the wood pellets have low economic efficiency as a raw material, and transportation costs are high from a manufacturing site to a demand area, which is expensive.

그러나, 본 발명은 표고버섯을 재배하고 발생하는 톱밥 폐배지를 이용하여 제조하기 때문에, 버섯을 재배하는 농촌지역에서 제조할 수 있고, 농촌지역은 겨울철 작물재배 시에 필요한 난방을 위한 수요가 매우 높아서, 가격경쟁력과 시장성을 갖춘 제품을 제공할 수 있다. 또한, 폐기되는 폐배지로 인한 환경적인 오염을 방지하고 신 재생에너지로 사용함으로써 농촌지역 현장에 매우 적합한 기술로 산업적 이용가능성이 매우 높은 기술이다.However, since the present invention can be manufactured in a rural area where mushrooms are grown because the mushroom is produced using the sawdust waste medium produced from the cultivation of shiitake mushrooms, the demand for heating required for cultivation of winter crops in rural areas is very high , Price competitiveness and marketability. In addition, it is an industrially highly utilized technology that is suitable for rural area by preventing environmental pollution caused by waste paper waste and using it as renewable energy.

본 발명의 우드펠릿의 제조방법, 폐자재인 버섯톱밥 폐배지의 폐톱밥을 이용하여 연료로 사용 가능한 우드펠릿을 제조하는 방법을 제공한다. 상기 우드펠릿은 곰팡이 발생을 줄여서 향상된 보관성을 가지며, 버섯재배 등의 과정에서 목질이 연화된 톱밥을 이용하므로 연소효율이 좋고 연소시 발생하는 냄새 등도 줄어든 우드펠릿을 제공할 수 있다.The present invention also provides a method for producing wood pellets usable as fuel by using the waste wood pulp of waste wood pulp, which is waste material. The wood pellets have improved storage properties by reducing the generation of fungi. The wood pellets have good combustion efficiency and reduced odor when burned, because they use sawdust softened in the process of mushroom cultivation.
