Description
본 발명은 각 가정 및 음식점, 단체급식소 등에서 배출되는 남은 음식물을 처리하여 이를 동물사료화하는 시스템에 관한 것으로, 특히 음식물 처리 공정이 원활하며 악취가 발생하지 않고 음식물에 있는 영양소 파괴를 극소화하여 고품질의 동물사료를 생산하는 방법에 관한 것이다.The present invention relates to a system for treating the remaining food discharged from each home, restaurant, group food service, etc. to animal feed, in particular, the food processing process is smooth, the odor does not occur and minimizes the destruction of nutrients in the food of high quality animals A method of producing a feed.
일반적인 음식물쓰레기 재활용 처리기술을 살펴보면 자연건조방식, 탈수감량방식, 열풍건조방식, 혐기성 발효방식 및 액상사료화 방식으로 대별할 수 있다. 특히 탈수감량방식이나 열풍건조방식 등은 단품기기로 처리토록 되어 있다.The general food waste recycling technology can be classified into natural drying method, dehydration reduction method, hot air drying method, anaerobic fermentation method and liquid feed method. In particular, the dehydration reduction method and the hot air drying method are treated as single equipment.
그러나 자연건조방식은 남은 음식물에 수분조절제(톱밥등)를 혼합하여 자연적으로 건조시켜 퇴비로 이용하는 방식으로서 이 방법은 처리기간이 많이 소요되고 악취 및 각종 잡균의 번식으로 인해 또 따른 환경오염을 유발한다.However, the natural drying method is a method of mixing the leftover food with moisture control agent (sawdust, etc.) and drying it naturally to use as compost. This method takes a lot of processing time and causes further environmental pollution due to the propagation of odor and various germs. .
열풍건조방식은 수분함량이 많은 음식물을 고온 열풍으로 건조시키므로서 음식물이 보유한 영양소가 파괴되며 또 탄화현상 등으로 퇴비는 가능하나 사료로 사용하기에는 거의 용이치 못하다.Hot air drying method is to dry food with a lot of moisture by high temperature hot air, which destroys the nutrients of food and composting due to carbonization, but it is hard to use as feed.
혐기성 발효방식은 대용량의 탱크에 남은 음식물과 발효제나 미생물을 투입하여 퇴비화하는 방식으로 악취로 인한 2차오염과 미생물이나 발효제의 양생에는 고도의 기술이 필요하며 전문가가 아니면 운용하기 힘들다.Anaerobic fermentation is a method of composting food and fermentation agents or microorganisms left in a large-capacity tank. Secondary pollution due to odors and curing of microorganisms or fermenters require advanced technology and are difficult to operate without experts.
액상사료화 방식은 큰 용기에 남은 음식물을 넣어 높은 온도로 끓여 사료화 하는 방식으로서 음식물에 포함된 이물질 선별이 어려우며, 특히 여름철 각종 유해성 미생물의 오염에 의해 생산즉시 소비하지 않으면 변질될 우려가 있다.The liquid feed method is a method of putting food left in a large container to boil at a high temperature to make it difficult to sort out foreign substances contained in the food, and in particular, if it is not consumed immediately due to the contamination of various harmful microorganisms in summer, there is a risk of deterioration.
이러한 문제점을 해결하기 위해 본 출원인에 의해 선출원된 출원번호 제 호의 진공건조기를 이용하여 처리시 악취 및 환경오염물질이 발생되지 않도록 하고, 양질의 동물사료로 재활용하여 저렴한 가격으로 축산농가에 공급함으로써 소득증대에 일조를 할 수 있도록 하는 음식물쓰레기를 사료화하는 방법을 제공하데 그 목적이 있다.In order to solve this problem, by using the vacuum dryer of the applicant No. No. filed previously filed by the present applicant to prevent odors and environmental pollutants generated during processing, it is recycled with high quality animal feed and supplied to livestock farms at low prices Its purpose is to provide a way to feed food waste that can contribute to the increase.

이하, 본 발명의 시스템을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the system of the present invention will be described in detail with reference to the accompanying drawings.
본 발명의 음식물쓰레기 사료화 시스템은 두 가지 공정으로 이루어질 수가 있다. 첫째는 분말화된 사료를 얻는 시스템이고, 둘째는 펠렛형 사료를 제조하는 공정이다.Food waste feeding system of the present invention can be made in two processes. The first is a system for obtaining powdered feed, and the second is a process for producing pelleted feed.
먼저 분말화 사료를 얻는 시스템은 도 1에 도시된 바와 같이 선두부에는 음식물쓰레기를 투입하는 투입호퍼(10)가 설치되어 있다. 이 투입호퍼(10)에 차량으로 수거된 음식물쓰레기를 투입한다. 투입된 음식물쓰레기에는 많은 악취가 발생하게 되는 데 이를 방지하기 위해 호퍼의 상부에 음식물을 투입할 때는 개방시키고 투입완료후에는 닫을 수 있는 개폐도어가 설치되어 있다. 또한 투입되는 음식물쓰레기는 점성이 있어 내부로 잘 유입되지 않게 됨으로 내부에는 투입되는 음식물쓰레기를 교반시켜 원활히 흘러내려가도록 도면에 도시되지 않은 임펠러가 설치되어 있다.First, the powdered feed system is provided with an input hopper 10 for feeding food waste at the head as shown in FIG. 1. The food waste collected by the vehicle is thrown into this input hopper 10. In order to prevent this, many food odors are introduced. To prevent this, open / close doors are installed to open the food in the top of the hopper and close after the food is finished. In addition, since the food waste is viscous and does not flow well into the inside, the impeller (not shown) is installed to smoothly flow down the food waste to be introduced.
투입호퍼(10)의 다음위치에는 파쇄기(20)가 설치되어 있어 투입호퍼(10)의 음식물쓰레기를 이송스크루컨베이어(130)로 이송시켜 파쇄기(20)로 음식물쓰레기를 잘게 파쇄하는 파쇄공정이 수행된다. 이때 음식물은 크기 형상 및 종류가 다양하여 일반적인 파쇄기(20)(crusher)로는 파쇄에 많은 문제점이 있어 음식물 파쇄에 적합한 치형롤러형으로 각각의 롤러 회전수를 달리하여 음식물을 고속으로 짓누르며 파쇄시키도록 되어 있다.The crusher 20 is installed at the next position of the input hopper 10 so that the food waste of the input hopper 10 is transferred to the transfer screw conveyor 130 to perform the crushing process of finely crushing the food waste with the crusher 20. do. At this time, the food has a variety of sizes, shapes and types, so that there is a lot of problems in crushing with the general crusher 20 (crusher), so as to crush and crush the food at high speed by varying the number of roller rotation of each of the teeth roller type suitable for food shredding. It is.
파쇄기(20)로 파쇄된 음식물쓰레기는 이어서 설치된 탈수기(30)로 공급되어 탈수공정이 이루어진다. 음식물은 80%∼90%의 수분을 함유하고 있어 이를 일부 제거하여야만 후술될 건조공정을 빠르고 경제적으로 수행하게 한다. 이때 탈수기(30)는 파쇄기(20)와 연속적으로 이루어져 있으며 스크루프레스형으로 이루어져 파쇄기(20)에 의해 파쇄된 음식물쓰레기는 연속적으로 탈수공정이 이루어지게 된다.Food waste shredded by the shredder 20 is then supplied to the installed dehydrator 30 is a dehydration process. The food contains 80% to 90% of water so that some of the water must be removed to allow the drying process to be described later to be performed quickly and economically. At this time, the dehydrator 30 is made of a crusher 20 continuously and consists of a screw press type food waste crushed by the crusher 20 is a continuous dehydration process is made.
탈수된 음식물쓰레기는 이송스크루컨베이어(130)를 통해 진공건조기(40)로 공급되어 건조공정을 거치게 된다. 이 공정은 건식사료화하기 위해 반드시 건조과정이 필요하므로 진공건조기(40)를 통해 반드시 건조공정을 수행하게 된다. 진공건조기(40)는 본 출원인에 의해 출원된 실용신안 출원 제 98-8206 호에 소개된 바 있다.The dehydrated food waste is supplied to the vacuum dryer 40 through the transfer screw conveyor 130 and undergoes a drying process. This process is a dry process is necessary in order to dry feed so that the drying process must be performed through the vacuum dryer (40). Vacuum dryer 40 has been introduced in Utility Model Application No. 98-8206 filed by the applicant.
음식물쓰레기를 건조시킴에 있어서 기존의 열풍건조방식을 사용할 수도 있으나 이 방식은 열효율이 낮을 뿐아니라 고온에 의해 음식물의 영양가를 파괴시킴과 동시에 또 재료가 탄화되는 문제점이 있어 지양해야될 장치이며, 본 출원인에 의해 고안된 진공건조기(40)는 음식물쓰레기를 저온 약 30℃∼80℃에서 고속건조시킬 수 있는 진공(30∼70㎝Hg)건조기이므로 영양가의 손실을 방지할 뿐아니라 유해성미생물을 진공상태에서 사멸시켜 고품질의 건조사료를 생산할 수 있다.In the drying of food waste, the existing hot air drying method may be used, but this method is not only low thermal efficiency, but also destroys the nutritional value of food by high temperature and at the same time, it is a device that should be avoided. The vacuum dryer 40 devised by the applicant is a vacuum (30-70 cmHg) dryer that can dry food waste at a low temperature of about 30 ℃ to 80 ℃ at high speed, so as not only to prevent the loss of nutritional value, but also to remove harmful microorganisms in a vacuum state. It can be killed to produce high quality dry feed.
또 냉각설비를 설치하여 진공펌프의 진공효율을 한층더 높이므로써 진공건조기(40)의 기능을 향상시켰다.In addition, by installing a cooling system to further increase the vacuum efficiency of the vacuum pump to improve the function of the vacuum dryer (40).
이와 같이 진공건조된 제품을 다음공정을 위해 진공건조기(40)와 이어서 이송스크루컨베이어(130)를 통해 저장탱크(50)에 일시 저장시키게 된다. 저장된 제품이 굳거나 덩어리질 수 있으므로 내부에 도면에 도시되지 않은 교반장치를 설치하여 굳거나 덩어리지는 것을 방지하였으며, 이는 또 배출시 원활한 배출이 이루어지게 된다.The vacuum-dried product as described above is temporarily stored in the storage tank 50 through the vacuum dryer 40 and then the transfer screw conveyor 130 for the next process. Since the stored product may be solidified or agglomerated, a stirring device not shown in the drawings may be installed to prevent the solidified or agglomerated, which may be smoothly discharged.
저장호퍼와 연이어서 정선기(60)가 설치되어 정선공정이 이루어진다. 음식물쓰레기에는 사료화할 수 없는 이물질이 상당히 많이 포함되어 있다. 이러한 이물질을 완벽하게 선별하지 못하면 사료로 재활용이 불가능하다. 따라서 정선기(60)로 정선공정을 반드시 거쳐야 한다. 이러한 본 정선기(60)가 진공건조기(40)의 다음 위치에 설치되는 것은 젖은 음식물에 포함된 이물질의 선별이 난해하므로 진공건조후에 선별공정을 거치도록 한 것이다. 이러한 선별기는 드럼형식의 정선기(60)를 채택하였다.The selector 60 is installed after the storage hopper and the selection process is performed. Food waste contains significant amounts of foreign matter that cannot be fed. If these foreign substances are not fully screened, they cannot be recycled as feed. Therefore, the selector 60 must go through the selection process. The main selector 60 is installed at the next position of the vacuum dryer 40 so that it is difficult to sort out foreign matters contained in wet food, so that the sorting process is performed after vacuum drying. This sorter adopted a drum type selector 60.
정선기(60)를 거쳐 이물질이 제거된 음식물쓰레기는 분쇄공정을 거치게 된다. 즉, 정선기(60)로 정선된 제품을 후술될 2차건조공정시 그 효율을 높이기 위해 부드러운 분말로 분쇄할 필요가 있다. 이때 분쇄기(70)는 습도가 높은 제품을 분말화 하기에 적합한 고속회전날을 여러단 장착한 분쇄기(70)를 사용하였으며, 배출시 분진비산방지를 위해 도면에 도시되지 않은 배출슈트를 설치하였다.The food waste from which foreign substances are removed through the selector 60 is subjected to a grinding process. That is, it is necessary to grind the product selected by the selector 60 into a soft powder in order to increase the efficiency during the secondary drying process to be described later. At this time, the pulverizer 70 used a pulverizer 70 equipped with a plurality of high-speed rotary blades suitable for pulverizing the product with high humidity, and installed a discharge chute not shown in the drawings to prevent dust scattering during discharge.
이와 같이 분쇄기(70)를 통해 분말화된 음식물쓰레기는 이송스크루컨베이어(130)를 통하여 저진공 연속건조기(80)로 공급되어 재건조되는 2차건조공정을 거친다. 이는 장기간 보관이 가능하도록 하는 공정으로서 연속적으로 흘러가면서 건조되는 구조로 되어 있다. 건조탱크의 내부온도는 영양손실 및 탄화현상을 방지하기 위해 50∼80℃를 유지하도록 도면에 도시되지 않은 열풍조절장치를 하였으며 열풍발생장치는 버너의 연통에서 배출되는 잔열을 회수하여 공기예열기(82)를 이용하여 에너지를 재활용하도록 하였다. 또 열풍에 의해 발생되는 분진은 도면에 도시되지 않은 사이클론(84)으로 집진하여 외부로 분진이 누출되는 것을 방지하였다.The food waste powdered through the grinder 70 is supplied to the low vacuum continuous dryer 80 through the transfer screw conveyor 130 and undergoes a second drying process to be re-dried. This is a process that allows long-term storage and has a structure that dries while flowing continuously. In order to prevent nutrient loss and carbonization, the internal temperature of the drying tank has a hot air control device not shown in the drawing, and the hot air generator recovers the residual heat discharged from the burner communication and preheats the air. ) To recycle energy. In addition, dust generated by hot air was collected by a cyclone 84 (not shown) to prevent dust from leaking to the outside.
2차건조공정을 통과한 음식물 쓰레기는 잠시저장탱크(50)에 저장되었다가 2차선별공정을 거치게 된다. 즉, 건조(수분함유량 20%이하)된 제품을 다시 한번 정선기(60)로 정선하여 이물질을 제거하고 이때 선별된 이물질은 퇴비사용이 가능하며 제품은 마그네트선별기(90)를 이용하여 금속류의 이물질(쇳가루)까지 완전히 선별하여 완전한 사료를 생산하도록 하였다.Food waste that has passed the secondary drying process is temporarily stored in the storage tank 50 and then subjected to the secondary screening process. That is, the dried (moisture content 20% or less) to select the product once again with the selector 60 to remove the foreign matter at this time, the selected foreign matter can be used compost and the product using the magnet separator (90) of the metal foreign matter ( All sorts of vegetables were selected to produce a complete feed.
이와 같이 이물질이 완전히 제거된 후에는 포장기(120)로 공급되어 동물사료로 공급이 용이하도록 일정한 단위로 포장하는 공정을 거친다. 포장된 사료포대는 수요처에 공급한다.After the foreign matter is completely removed in this way is supplied to the packaging machine 120 is subjected to a process of packaging in a predetermined unit to facilitate the supply to the animal feed. Packaged feed bags are supplied to the consumer.

(제2실시예)Second Embodiment
두 번째의 펠렛형 사료를 얻는 공정은 도 2에서와 같이 분말 사료를 얻는 시스템과 같이 음식물쓰레기 투입공정, 파쇄공정, 탈수공정, 진공건조기(40)를 통한 진공건조공정, 저장탱크(50)에 저장공정, 정선기(60)를 통한 정선공정, 분쇄공정을 거친 후 2차선별공정을 거친다.The process of obtaining a second pellet-type feed is a food waste input process, a crushing process, a dehydration process, a vacuum drying process through a vacuum dryer 40, and a storage tank 50 as in a system for obtaining a powder feed as shown in FIG. After the storage process, the selection process through the selector 60, the crushing process is subjected to the secondary screening process.
2차선별공정을 통과한 음식물쓰레기는 펠렛기(100)(pellet)를 이용하여 적당한 크기로 펠렛가공한다.Food waste that has passed the second sorting process is pelletized to a suitable size using a pellet machine (100) (pellet).
펠렛기(100)로 제조된 펠린형 사료는 2차연속건조공정을 거친다. 이는 펠렛화된 사료를 장기간 보관하기 위해 그리고 유통과정에서의 변질을 방지하기 위해서 수분함유량을 13% 이하로 낮추어야 하기 때문이다. 이때 펠렛가공된 사료는 습도가 높은 상태이므로 부스러질 우려가 있어 특별히 2차연속건조기(110)를 이용하여 펠렛형상을 그대로 유지하면서 건조시킨다. 2차연속건조기(110)는 투입에서 배출까지 연속적으로 흘러가면서 적절한 온도에서 건조되어야 하며 펠렛화된 사료가 부서지지 않도록 부드럽게 흘러갈 수 있도록 도면에 도시되지 않은 킬든형에 스크루 가이드를 설치하였다. 또 직화를 방지하기 위해 화실을 별도설치하여 화실내에서 완전연소된 적당한 열기만 건조기에 송풍되도록 하였다. 또 열기의 효율을 최대한 높이기 위해 도면에 도시되지 않은 건조탱크의 내부에 열기분산장치를 설치하였고 또 건조 효율을 높이기 위해 습한 공기는 도면에 도시되지 않은 터보팬을 이용하여 강제 배출시키며 분진은 사이클론(84)으로 집진하여 외부로 분진이 누출되는 것을 방지하였다.The pelleted feed prepared by the pellet machine 100 undergoes a second continuous drying process. This is because the moisture content must be lowered to 13% or less in order to store the pelleted feed for a long time and to prevent deterioration in the distribution process. At this time, the pellet processed feed is in a high humidity state, so there is a risk of crumbs, and is dried while maintaining the pellet shape using a second continuous dryer 110. The secondary continuous dryer 110 has to be dried at an appropriate temperature while flowing continuously from the input to the discharge, and a screw guide is installed in the Kilden type not shown in the drawing so that the pelletized feed can flow smoothly so as not to be broken. In addition, to prevent direct fire, the firebox was installed separately so that only the proper heat completely burned in the firebox was blown to the dryer. In order to maximize the efficiency of the heat, a heat dissipation device was installed inside the drying tank not shown in the drawing. In order to increase the drying efficiency, wet air was forced out by using a turbo fan not shown in the drawing. 84) to prevent dust from leaking to the outside.
이와 같이 펠렛가공된 사료가 2차건조기(110)를 통해 2차건조되면 거의 60∼80℃의 온도를 유지하고 있기 때문에 즉시 포장작업을 수행하지 못한다. 따라서 냉각건조기(190)를 통해 냉각건조공정을 거친다. 냉각건조기(190)는 펠렛형 사료가 연속적으로 이동하도록 하면서 도면에 도시되지 않은 휀을 이용 송풍하여 온도를 식혀주는 구조로 되어 있다.In this way, the pellet-processed feed is secondaryly dried through the secondary dryer 110, and thus does not immediately perform packaging because it maintains a temperature of about 60 to 80 ° C. Therefore, the cooling dryer 190 goes through a cooling drying process. Cooling dryer 190 has a structure that cools the temperature by blowing by using a fan (not shown) while allowing the pellet feed to move continuously.
마지막으로 포장기(120)를 통한 포장공정을 거쳐 각 수요처에 공급한다.Finally, the package is supplied to each customer through a packing process through the packing machine 120.
