고 수분 원료의 2단 펠렛 성형방법{Method for pelletizing the succulent materials by two step}Method for pelletizing the succulent materials by two step}

도 1은 본 발명의 공정을 개락적으로 나타낸 도면이다.1 is a diagram schematically showing the process of the present invention.

본 발명은 고 수분 원료의 2단 펠렛 성형방법에 관한 것으로, 좀 더 구체적으로는 원재료의 함수율이 30∼50%를 포함하는 재료들을 2단계에 걸친 펠렛 가공으로 성형하는 고 수분 원료의 2단 펠렛 성형방법에 관한 것이다.The present invention relates to a two-stage pellet molding method of a high moisture raw material, and more specifically, a two-stage pellet of a high moisture raw material for molding materials containing a water content of 30 to 50% by two steps of pellet processing. It relates to a molding method.

펠렛의 형태는 원료를 잘게 분쇄하고 이를 혼합하여 강제적으로 다이를 통하여 배출되는 형태로써 일정간격으로 절단한 형태를 가지고 있다. 이는 가축용 배합사료 및 폐기물의 분쇄처리 등에 주로 사용되고 있는 방식으로써 널리 이용되고 있다.Pellets are pulverized into small pieces, mixed with them, and are forcibly discharged through a die. The pellets are cut at regular intervals. This is widely used as a method that is mainly used for the pulverization treatment of livestock compound feed and waste.

한편, 주변에서 발생할 수 있는 농산물 폐기물, 축산폐기물 등은 매립하거나 사료화, 비료화, 기타용도로 이용할 수 있으나, 이들 원재료가 가지는 부피와 함수율에 의한 처리문제 때문에, 이들을 줄이기 위하여 강제로 압착하거나 분쇄, 건조시키는 등의 추가적인 공정이 필요하였다.On the other hand, agricultural wastes and livestock wastes, which may occur in the surrounding area, can be used for landfilling, feed, fertilization, and other uses.However, due to the problems of processing due to the volume and moisture content of these raw materials, they are forcedly compressed, crushed, and dried. An additional process, such as, was required.

일반적으로 이들의 처리는 적정 함수율이 될 때까지 강제로 열을 가하여 수분을 증발시키고 펠렛 성형을 하거나 펠렛 성형한 이후에 열을 가하여 수분을 증발시키는 방식이 주로 사용되고 있으나, 별도의 가열설비와 함께 에너지 비용이 추가적으로 포함되기 때문에 제조단가를 상승시킬 뿐 아니라, 가열하게 함으로써 원재료가 열 변형을 일으킬 수 있고, 가열공정에 수반되는 냉각공정이 반드시 필요한 문제가 있었다.In general, these treatments use a method of forcibly evaporating water by forcing heat until a proper moisture content is reached and pelletizing or after evaporating water by heating after pellet molding, but energy with a separate heating facility is used. Since the cost is additionally included, as well as raising the manufacturing cost, by heating the raw material may cause thermal deformation, there was a problem that the cooling step accompanying the heating step is necessary.

또한, 종래의 경우에는 펠렛의 경우 1차 압출을 통해서만 형성되었기때문에 펠렛의 강도가 약하여 입자의 조직이 쉽게 부서질 수 있는 문제로 인하여 저장 중에 수분이 쉽게 침투되고 사용시에는 부스러기 등이 발생하거나, 수분이 완전하게 마르지 않을 경우 서로 달라붙어 덩어리진 형태가 발생되는 문제가 있었다. In addition, in the conventional case, since the pellet is formed only through the first extrusion, moisture is easily penetrated during storage due to the weak strength of the pellet and the structure of the particles can be easily broken, and debris or the like occurs during use. If it is not completely dry, there was a problem that agglomerated forms are stuck to each other.

따라서, 본 발명에서는 이러한 문제점을 개선하고 수분함량을 낮추며 강도가 증대된 펠렛 형태의 제품을 생산하는 데 그 목적이 있다.Therefore, the present invention aims to improve these problems, to lower the moisture content and to produce a product in the form of pellets of increased strength.

본 발명에서는 원재료의 함수율이 30∼50%를 포함하는 재료들을 2단계에 걸친 펠렛 가공으로 성형하는 것을 특징으로 하고 있다. 1차 펠렛 가공된 원재료는 분쇄 및 압출되는 형태로써 다이를 통과하게 됨으로써 일차적으로 함수율이 감소하게 된다. 이렇게 배출된 펠렛들은 다시 직경이 1차보다 작은 다이(die)를 통과 하게 됨으로써 밀도가 상승하고 강도가 증대되게 된다. 또한, 1차 펠렛 공정보다 직경이 작은 다이를 통과하게 하여 분쇄된 재료들 간에 마찰열이 발생함으로써 수분이 제거되는 효과를 나타내게 된다. 아울러, 본 발명에서는 2차 펠렛 형태로 성 형된 재료는 강제 냉각형태로써 냉각 및 건조가 이루어지게 됨으로써 충분한 강도를 갖는 형태로 성형됨을 특징으로 한다.The present invention is characterized in that the material containing a water content of 30 to 50% of the raw material is molded by two steps of pellet processing. Primary pelleted raw materials are passed through the die in the form of grinding and extrusion, thereby primarily reducing the moisture content. The pellets thus discharged again pass through a die of smaller than primary diameter, increasing density and increasing strength. In addition, the friction heat is generated between the pulverized materials by passing through a die having a diameter smaller than that of the primary pellet process, thereby exhibiting the effect of removing moisture. In addition, in the present invention, the material formed in the form of secondary pellets is characterized by being molded into a form having a sufficient strength by being cooled and dried in the form of forced cooling.

따라서, 본 발명의 고 수분 원료의 2단 펠렛 성형방법은 전체 함수율이 30%∼50%을 갖는 유기물을 1차 펠렛 밀에 투입하여 분쇄 및 혼합과정을 거쳐 직경 5∼15㎜의 다이(die)를 통하여 배출하여 1차 펠렛을 성형시키는 단계; 상기 1차 성형된 펠렛을 저온냉각건조기에서 1차 건조, 냉각시키는 단계; 상기 1차 건조 냉각된 펠렛을 2차 펠렛 밀에 투입하여 직경 3∼10㎜의 다이(die)를 통하여 배출시켜, 2차 펠렛을 성형시키는 단계; 및 상기 2차 성형된 펠렛을 저온냉각건조기에서 2차 건조, 냉각시키는 단계로 구성된다.Therefore, in the two-stage pellet molding method of the high moisture raw material of the present invention, a die having a diameter of 5 to 15 mm is subjected to a pulverization and mixing process by introducing an organic material having a total water content of 30% to 50% into a primary pellet mill. Ejecting through to form the primary pellets; Primary drying and cooling the first molded pellets in a low temperature cooling dryer; Inserting the primary dry cooled pellets into a secondary pellet mill and discharging them through a die having a diameter of 3 to 10 mm to form secondary pellets; And secondary drying and cooling the secondary molded pellets in a low temperature cooling dryer.

이하 본 발명의 펠렛 성형방법을 좀 더 구체적으로 설명하면 다음과 같다.Hereinafter, the pellet molding method of the present invention will be described in more detail.

먼저, 수분함수율이 30%∼50%의 유기물 등을 1차 펠렛 밀에 투입하여 직경이 5㎜∼l5㎜의 입자로 압출하여 1차 펠렛을 성형하는 것으로써, 투입되는 재료는 사료, 비료, 기타 용도로 이용할 수 있는 재질로써, 퇴비, 부산물비료, 돈분, 축분, 계분, 음식물 쓰레기, 및/또는 탈수폐기물 등이 될 수 있다. 상기 유기물의 수분함수율이 30% 미만이면 종래의 방법과 같이 1단계의 펠렛 성형작업만으로도 펠렛 성형화가 가능하고, 50%를 초과하면 수분이 너무 많아서 접착력이 약하여 펠렛밀로서는 펠렛 성형화가 어렵고 압출기(익스트루더)형태의 기계로 압출하여 절단하는 방법으로 해야하는데 수분이 많아서 제품이 강도가 매우 약하고 서로 들러 붙거나 문들어져서 제품의 형태를 유지하기가 어려워서 대형건조시설이 필요하게 된다.First, an organic material having a water content of 30% to 50% or the like is introduced into a primary pellet mill and extruded into particles having a diameter of 5 mm to l5 mm to form a primary pellet. Materials that can be used for other purposes may be compost, by-product fertilizers, pig meals, animal meals, granules, food waste, and / or dehydrated waste. When the water content of the organic matter is less than 30%, pellet molding may be performed by only one step of pellet molding as in the conventional method, and when the water content exceeds 50%, the pellet may be difficult to form in a pellet mill and the extruder (ex) Extruding and cutting with a Trudder type machine should be done. The moisture content is so high that the products are very weak and difficult to maintain the shape of the products because they stick together or rubbed together.

본 발명에 따르면, 펠렛 밀에 투입된 이들 재료들은 혼합 및 분쇄과정을 거친 후, 강제적으로 압출된다. 펠렛은 압출되는 다이표면에서 일정한 크기로 절단시키는 형태로써 배출된다. 펠렛 밀을 통해 압출되는 이들 원료는 분쇄되며 혼합되는 과정을 거쳐서 다이의 구멍을 통하여 압출 될때에 70∼80℃의 고열의 마찰열과 압축열이 발생하게 됨으로써 일정수분(약 1∼2%)이 증발하게 된다. 이때 발생하는 고열에 의하여 섬유질이나 곡물들은 익혀지게 되어 익힌 상태(젤라틴화)가 되어 서로 점착력을 같게 되는 특성을 갖게 되어 배출되어 1차 펠렛을 형성하는 단계가 마무리된다.According to the invention, these materials introduced into the pellet mill are forcibly extruded after mixing and grinding. The pellets are discharged in the form of cutting to a constant size on the die surface to be extruded. These raw materials, which are extruded through the pellet mill, are pulverized and mixed, and when extruded through the holes of the die, high-temperature frictional heat and compression heat of 70 to 80 ° C generate a certain amount of moisture (about 1 to 2%). Done. At this time, the fibers or grains are cooked by the high heat generated to become a cooked state (gelatinized) to have the same adhesive force to each other and is discharged to form a primary pellet.

본 발명에 있어서, 상기 펠렛 밀의 다이 구멍 직경이 5㎜∼l5㎜로 하는 이유는 분쇄와 1단계 펠렛 성형이 용이하게 하기 위하여 이며, 5㎜ 미만이면 펠렛 성형율은 향상되지만 분쇄동력과 1단계 펠렛 성형에 필요한 동력이 과도하게 소요되고, l5㎜를 초과하게 되면 분쇄는 용이하게 되지만 1단계 펠렛 성형이 이루어지지 않고, 펠렛 성형율이 현저히 떨어지는 경향이 있다.In the present invention, the die hole diameter of the pellet mill is 5mm to l5mm for the purpose of facilitating pulverization and one-step pellet molding. If the thickness is less than 5mm, the pellet forming rate is improved, but the grinding power and the one-step pellet are When the power required for molding is excessively exceeded, when it exceeds l5 mm, grinding is easy, but one-stage pellet molding is not performed, and the pellet forming ratio tends to be significantly lowered.

1차 펠렛으로 성형이 완료된 재료는 이들을 건조시키고 강도를 증대시키는 건조작업이 필요하다. 본 발명에서는 1차 펠렛의 건조에 있어서 열풍이 아닌 상온의 공기인 냉풍을 이용하게 함으로써, 열풍건조에 의한 열 변성을 방지하고 가열에 필요한 전기나 스팀 등 에너지(열원)를 절감하는 효과를 가지게 하였다.Materials that have been molded into primary pellets require drying to dry them and increase their strength. In the present invention, by using cold air that is air at room temperature, not hot air, in drying the primary pellets, it is possible to prevent thermal denaturation due to hot air drying and to reduce energy (heat source) such as electricity or steam required for heating. .

상기 저온건조 방식은 밀폐된 공간에 1차 펠렛을 넣은 상태에서 일측 입구에서는 외기를 공급해주고 타측 입구로는 내측공간의 공기를 강제적으로 배출시키는 형태를 이루게 함으로써 건조실의 공간이 대기압보다 낮은 약한 진공상태를 유지하 게 하여 건조속도 및 냉각 속도를 빠르게 하는 특성을 부여하게 된다. 이러한 공기순환 방식은 일방향으로 보내주거나 일방향으로 빼주는 방식보다 건조속도를 더욱 증대시키도록 구성한 것으로써 1차 건조냉각에서 펠렛 수분의 5∼6%정도 증발시킬 수 있다. 이때의 상기 공기 온도는 10∼25℃ 정도가 바람직하며, 10℃ 미만이면 냉각엔 유리하지만 건조에는 불리하고, 25℃를 초과하면 냉각엔 불리 하지만 건조에는 유리한 경향이 있다.The low temperature drying method is a weak vacuum state in which the space of the drying chamber is lower than atmospheric pressure by supplying outside air at one inlet and forcibly discharging air in the inner space at the other inlet while the primary pellet is placed in a closed space. It is given to the characteristics to accelerate the drying rate and cooling rate by maintaining. The air circulation system is configured to further increase the drying speed than the one-way or one-way pull method, and may evaporate about 5 to 6% of the moisture of the pellets in the primary dry cooling. At this time, the air temperature is preferably about 10 to 25 ° C., and less than 10 ° C. is advantageous for cooling, but disadvantageous for drying.

한편, 상기 건조 냉각된 1차 펠렛은 콘베어벨트로 이송되어 2차 펠렛을 성형하기 위해 펠렛 밀 내측으로 공급되며, 2차 펠렛밀에서 다시 분쇄와 혼합이 이루어진 후, 강제적으로 압출이 이루어지게 된다. 2차 펠렛 밀의 구멍직경은 3∼10㎜로써 1차 펠렛 밀의 다이 구멍 직경보다 감소된 것을 특징으로 하고 있다. 2차 펠렛은 1차 펠렛보다 구멍의 직경이 작음으로써 압출될 때 다이 구멍(hole)과 압출되는 원료의 조직간의 저항을 증대시킴으로써 1차 펠렛 성형 때보다도 더 높은 80∼90℃의 압축열과 마찰열을 발생하게 하고 그 열기에 의해 수분증발효과(약 1∼2%)를 발생함과 동시에, 압출된 조직간에 열기와 압축력에 의하여 표면상태가 단단하고 딱딱하게 변하고 더욱 견고한 접착력을 유지하게 된다.On the other hand, the dry-cooled primary pellets are conveyed to the conveyor belt and supplied into the pellet mill to form the secondary pellets, and after being crushed and mixed in the secondary pellet mill, the extrusion is forcibly made. The hole diameter of the secondary pellet mill is 3 to 10 mm, which is smaller than the die hole diameter of the primary pellet mill. Secondary pellets have a smaller hole diameter than primary pellets, which increases the resistance between die holes and the structure of the raw material being extruded when extruded, resulting in higher compression and frictional heat at 80-90 ° C than primary pellet molding. When the heat is generated and the water evaporation effect (about 1 to 2%) is generated, the surface state is changed hard and hard by the heat and compressive force between the extruded tissues and maintains a more firm adhesive force.

이렇게, 배출되는 압력이 1차 펠렛에서 보다 훨씬 높기 때문에 펠렛 내부의 조직이 치밀해지고 밀도가 상승하게 되어 더욱 단단한 형태로 2차 펠렛이 배출되는 단계가 마무리 된다.In this way, the pressure discharged is much higher than in the primary pellets, so that the tissue inside the pellets becomes dense and densified, thereby completing the step of discharging the secondary pellets in a more rigid form.

본 발명에 따르면, 상기 2차 펠렛 밀의 다이 구멍 직경은 3㎜∼l0㎜가 바람직한데, 이는 수요자가 가장 많이 요구하는 제품의 일반적인 규격이기 때문이며, 3 ㎜ 미만이면 성형하기가 어렵고 동력이 많이 소요되며 단위시간당 생산량이 떨어지며, l0㎜를 초과하면 제품의 강도가 약해지고 비료살포기의 노즐이 막히거나 하는 등 다른 기계와의 호환성에 문제가 발생하는 경향이 있다.According to the present invention, the die hole diameter of the secondary pellet mill is preferably 3 mm to 10 mm, because it is a general specification of the product that the consumer most demands, and if it is less than 3 mm, it is difficult to mold and requires a lot of power. The yield per unit time drops, and if it exceeds l0mm, there is a tendency that there is a problem in compatibility with other machines, such as weakened product strength and clogged nozzle of fertilizer spreader.

한편, 2차 펠렛으로 성형이 완료된 재료들이라고 해도, 펠렛 내부의 조직간에 포함된 수분으로 인하여 일정한 강도가 유지되지 않는 문제가 있다. 따라서 이들을 건조시키고 강도를 증대시키는 건조작업이 필요하다. 본 발명에 있어서, 2차 펠렛의 건조공정도 1차 건조 냉각 공정과 동일한 과정과 장치를 사용하여 수행하였다. 본 발명의 공기순환 방식은 일 방향으로 보내주거나 일 방향으로 빼주는 방식보다 건조속도를 더욱 증대시키도록 구성한 것으로써 1차 건조냉각단계 마다 펠렛의 수분을 5∼6%정도 증발시키게 되므로 1차 및 2차 건조냉각단계를 거치면 총 10∼12%정도의 수분을 증발시키는 단계를 마무리하게 된다.On the other hand, even if the material is completed in the secondary pellets, there is a problem that the constant strength is not maintained due to the moisture contained in the tissue inside the pellets. Therefore, a drying operation for drying them and increasing the strength is required. In the present invention, the drying process of the secondary pellet was also performed using the same process and apparatus as the primary dry cooling process. The air circulation system of the present invention is configured to further increase the drying speed than the method to send in one direction or to remove in one direction, so that the moisture of the pellet is evaporated by about 5 to 6% at each first drying cooling step. After the dry cooling step, a total of 10 to 12% of water is evaporated.

따라서 이와 같은 건조값으로써 원재료를 건조시킬 경우, 1차 및 2차 펠렛 공정 이후에 2∼4%의 수분함량이 증발되고, 1차 및 2차 저온건조 냉각기에 의해서 10∼12%의 수분이 건조되어, 건조되는 총 수분함량이 12∼16%까지 증대됨으로써, 최초 투입된 원료의 함수율이 30%일 경우는 최종수분이 14%∼18%로 떨어지는 특성이 있으며, 50% 함수율일 경우는 최종수분이 34∼38%로 감소되는 특성이 있다.Therefore, when the raw material is dried at such a dry value, the moisture content of 2 to 4% is evaporated after the primary and secondary pellet processes, and the moisture of 10 to 12% is dried by the primary and secondary low temperature drying coolers. As the total moisture content to be dried is increased to 12 to 16%, the final moisture content is 14% to 18% when the moisture content of the first raw material is 30%, and the final moisture content is 50% moisture content. It has a characteristic of being reduced to 34 to 38%.

도 1은 본 발명의 공정을 개략적으로 나타낸 도면으로, 원료공급부터 포장까지의 전체적인 공정을 개략적으로 잘 설명하고 있다.1 is a view schematically showing the process of the present invention, which schematically illustrates the overall process from raw material supply to packaging.

이러한 본 발명의 공정을 거친 펠렛의 충격강도는 약 90Kg/㎤ 이상으로, 이 정도의 충격강도는 포장, 운반, 수송 및 보관 등의 취급을 하는데 충분한 강도이 다.The impact strength of the pellets subjected to the process of the present invention is about 90 Kg / cm 3 or more, and this degree of impact strength is sufficient to handle packaging, transportation, transportation and storage.

이하 실시예를 통하여 본 발명을 좀 더 구체적으로 살펴보지만, 하기 예에 본 발명의 범주가 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the following examples, but the scope of the present invention is not limited to the following examples.

실시예 1Example 1

먼저, 퇴비 1,000㎏, 돈분 100㎏, 축분 100㎏, 맥주박 200㎏, 계분 100㎏와 음식물찌꺼기 500㎏의 혼합물의 수분함유량을 약 40%인 상태로 만들어 다이의 직경이 약 10㎜인 펠렛밀에서 혼합시키면서 분쇄시키고, 상기 분쇄물을 압출시켜 1차로 펠렛을 성형하였다. 상기 1차 가공된 펠렛의 함수율은 약 38%이었다.First, in a pellet mill having a diameter of about 10 mm, the water content of the mixture of 1,000 kg of compost, 100 kg of pig meal, 100 kg of beer powder, 200 kg of beer foil, 100 kg of flour and 500 kg of food waste was made about 40%. The mixture was pulverized and the pulverized product was first molded into pellets. The moisture content of the primary processed pellets was about 38%.
