음식물 쓰레기 발효 및 건조 장치Food waste fermentation and drying unit
본 발명은 가정이나 식당에서 주로 발생되는 음식물 쓰레기를 처리하는 장치에 관한 것으로서, 특히 음식물 쓰레기를 발효와 동시에 균일한 온도로 가열하면서 교반하여 습기를 제거함으로써 사료로 사용할 수 있도록 한 음식물 쓰레기 발효 및건조 장치에 관한 것이다.The present invention relates to a device for treating food waste mainly generated in a home or a restaurant, and in particular, fermentation and drying of food waste which can be used as feed by removing moisture by heating and stirring food waste to a uniform temperature at the same time. Relates to a device.
사람이 일상 생활을 하게 되면 많은 양의 쓰레기가 발생되는데, 이 쓰레기의 처리가 각 가정이나 사회 전체적인 문제가 되고 있다. 쓰레기는 보통 플라스틱이나 금속과 같은 재활용이 가능한 쓰레기와 재활용이 불가능한 쓰레기로 구분되는데, 재활용이 불가능한 쓰레기는 소각이나 매립 등의 방법으로 처리된다.When people do their daily activities, they generate a large amount of garbage, which is a problem for each household and society. Garbage is usually divided into recyclable waste such as plastic or metal and non-recyclable waste. Non-recyclable waste is disposed of by incineration or landfill.
쓰레기를 소각할 경우 냄새와 소각에 따른 부산물의 발생 등으로 여러 가지 문제가 야기되고 있으며, 매립의 경우에도 매립장 시설지 부족과 주민의 반대 및 침출수 유출 등으로 많은 문제를 내포하고 있다. 재활용이 불가능한 쓰레기의 대부분을 차지하는 것이 음식물 쓰레기로서 가정이나 식당 등에서 주로 발생되는데, 이들은 수분을 포함하고 있기 때문에 소각 비용이 많이 들고 매립시에는 침출수가 발생되어 악취를 풍기게 된다.Incineration of waste causes various problems due to the generation of odors and by-products due to incineration.In case of reclamation, there are many problems such as lack of landfill facilities, opposition of residents and leakage of leachate. Most of the non-recyclable garbage is food waste, which is mainly generated in homes and restaurants. Since these contain moisture, the incineration cost is high and leachate is generated when the landfill is odorous.
결국, 정부에서는 쓰레기 종량제 실시와 더불어 음식물 쓰레기에 대하여 건조후 쓰레기를 배출하도록 하고 있는 실정이다. 그럼에도 불구하고 음식물 쓰레기의 건조후 배출은 지지부진한 실정이며, 이들 음식물 쓰레기가 유기물로 이루어진 것을 감안하면 대단한 자원의 낭비가 아닐 수 없다.As a result, the government has decided to discharge the garbage after drying the food waste in addition to the waste-based system. Nevertheless, the post-drying discharge of food waste is poor, and considering that these food wastes are made of organic materials, it is a waste of resources.
따라서, 음식물 쓰레기를 건조 후 발효시켜 퇴비로 사용하거나 가축의 사료로 사용하고자 하는 여러 방법들이 제시되고 있다. 음식물 쓰레기를 탈수시키고 다른 퇴비와 혼합시켜 발효되도록 함으로써 음식물 쓰레기가 유기질 비료로 사용될 수 있도록 하는 방법이 제안되었으나, 음식물 쓰레기에 포함된 염분 등으로 인해 비료로 사용하기를 주저하고 있는 실정이다.Therefore, various methods have been proposed for drying and fermenting food waste to be used as compost or as feed for livestock. It has been proposed to dehydrate food waste and mix it with other compost so that it can be used as organic fertilizer. However, it is hesitant to use it as a fertilizer due to salts contained in food waste.
또, 음식물 쓰레기를 교반 압축하여 수분을 제거하고, 적절한 처리를 거쳐 가축의 사료로 사용하는 방법 또한 거론되었으나, 음식물 쓰레기를 교반할 때 음식물 쓰레기에 포함된 이물질에 의해 교반기의 동작이 중지되는 문제점이 있다.In addition, a method of stirring and compressing food waste to remove moisture and using it as a feed for livestock after proper treatment has also been discussed. However, when agitating the food waste, the operation of the agitator is stopped by foreign matter contained in the food waste. have.
본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 음식물 쓰레기를 발효와 동시에 균일한 온도로 가열하면서 교반하여 습기를 제거함으로써 사료로 사용할 수 있도록 한 음식물 쓰레기 발효 및 건조 장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, to provide a food waste fermentation and drying apparatus that can be used as feed by removing moisture by stirring the food waste while heating to a uniform temperature at the same time as fermentation. The purpose is.

상기와 같이 구성된 본 발명의 음식 쓰레기 발효 및 건조 장치는 음식물 쓰레기를 교반 및 가열하여 수분을 제거함과 동시에 발효시키게 된다.The food waste fermentation and drying apparatus of the present invention configured as described above is fermented while removing moisture by stirring and heating the food waste.
컨베이어(23)를 이용하여 투입구(12)로 음식물 쓰레기와 미생물을 투입하고 유압 모터(20)를 동작시키면 회전체(10)가 회전되면서 내부의 음식물 쓰레기를 교반시킨다. 이때, 음식물 쓰레기와 함께 투입된 미생물은 일정 온도에서 활성화되어 음식물 쓰레기를 발효시키게 된다.When the food waste and microorganisms are introduced into the inlet 12 using the conveyor 23 and the hydraulic motor 20 is operated, the rotating body 10 is rotated to stir the food waste inside. At this time, the microorganisms put together with the food waste are activated at a predetermined temperature to ferment the food waste.
회전체(10)의 회전 방향에 따라 음식물 스레기의 교반 또는 배출이 결정되는데, 유압 컨트롤러(21)를 이용하여 유압 모터(20)의 회전 방향을 변경한다. 교반시에는 회전체(10)를 정방향으로 회전시켜 음식물 쓰레기가 개구부쪽으로 빠져나가지 않게 하고, 배출시에는 회전체(10)를 역방향으로 회전시켜 음식물 쓰레기가 개구쪽으로 배출되도록 한다.The stirring or discharging of the food waste is determined according to the rotational direction of the rotating body 10, and the rotational direction of the hydraulic motor 20 is changed using the hydraulic controller 21. At the time of stirring, the rotating body 10 is rotated in the forward direction so that the food waste does not escape to the opening side, and when discharging, the rotating body 10 is rotated in the reverse direction so that the food waste is discharged toward the opening side.
이와 동시에 버너(15)를 이용하여 열매체(13)를 가열하게 되는데, 열매체(13)는 온도가 균일하게 상승되어 회전체(10) 내부의 음식물 쓰레기를 가열하게 된다. 버너(15)에 의해 발생된 연소 가스는 열매체(13)와 단열재(14) 사이에 형성된 가열 통로(16)를 따라 흐르면서 열매체(13)를 가열하고 굴뚝을 통해 빠져나간다. 따라서, 열매체(13)가 회전체(10)의 외주면에서 균일하게 회전체(10)를 가열하게 되고 회전체(10)는 계속 회전되므로 음식물 쓰레기는 회전체(10)의 내주면에 눌어 붙거나 타지 않게 된다.At the same time, the heat medium 13 is heated by using the burner 15. The heat medium 13 is heated to uniformly heat the food waste inside the rotating body 10. The combustion gas generated by the burner 15 flows along the heating passage 16 formed between the heat medium 13 and the heat insulating material 14 to heat the heat medium 13 and exit through the chimney. Therefore, since the heating medium 13 uniformly heats the rotating body 10 on the outer circumferential surface of the rotating body 10 and the rotating body 10 is continuously rotated, food waste is pressed or burned on the inner circumferential surface of the rotating body 10. Will not.
이때, 서모 컨트롤러(17)는 열매체(13)의 온도를 감지하여 버너(15)의 화력을 제어함으로써 열매체(13)가 항상 균일한 온도를 유지하게 하고, 단열재(14)는 버너(15)에 의해 발생된 열이 외부로 배출되지 않고 열매체(13)를 가열하는 데에만 사용되도록 한다. 또, 송풍기(26)는 회전체(10)의 내부로 산소를 공급하여 미생물에 의한 발효가 효과적으로 진행되도록 함과 동시에 열매체(13)의 음식물 쓰레기 가열에 의해 발생된 수증기를 외부로 배출시키는 역할을 한다.At this time, the thermo controller 17 senses the temperature of the heat medium 13 to control the thermal power of the burner 15 so that the heat medium 13 is always maintained at a uniform temperature, and the heat insulating material 14 is applied to the burner 15. The heat generated by this is not discharged to the outside and is used only for heating the heat medium 13. In addition, the blower 26 supplies oxygen to the inside of the rotating body 10 so that the fermentation by microorganisms can be effectively carried out and at the same time discharges water vapor generated by heating the food waste of the heat medium 13 to the outside. do.
음식물 쓰레기의 건조 및 발효가 거의 완료되면 회전체(10)를 역방향으로 회전시키게 된다. 회전체(10)가 역방향으로 회전되면 회전체(10) 내부에 형성된 나선형 홈(11)에 의해 음식물 쓰레기가 회전체(10)의 개구부쪽으로 이동되어 배출된다. 배출된 쓰레기는 호퍼(24)에 의해 포집되고, 스크린(25)에 의해 철근이나 기타 이물질이 걸러지게 된다. 걸러진 이물질은 폐기하고, 스크린(25)을 통과한 쓰레기를 적당한 형상으로 가공하여 가축의 사료로 사용한다.When the drying and fermentation of the food waste is almost completed, the rotating body 10 is rotated in the reverse direction. When the rotating body 10 is rotated in the reverse direction, the food waste is moved toward the opening of the rotating body 10 by the spiral groove 11 formed inside the rotating body 10 and discharged. The discharged waste is collected by the hopper 24 and the rebar or other foreign matter is filtered out by the screen 25. The filtered foreign matter is discarded, and the waste which has passed through the screen 25 is processed into a suitable shape and used as feed for livestock.
이와 같이, 본 발명의 음식물 쓰레기 발효 및 건조 장치는 통 자체가 회전되므로 교반 도중 이물질에 의해 정지되는 일이 없고 열매체를 사용하므로 회전체 내부의 온도를 균일하게 유지시킬 수 있으므로 미생물을 이용한 발효가 용이한 이점이 있다.As described above, the food waste fermentation and drying apparatus of the present invention is rotated by the container itself, so that it is not stopped by foreign substances during stirring, and since the heat medium is used, the temperature inside the rotating body can be maintained uniformly so that fermentation using microorganisms is easy. There is one advantage.
또, 기존의 발효기에 비해 적은 가격으로 제작할 수 있으며 인적, 물적 관리비가 절감되고 음식물 쓰레기를 이용한 제품을 대량 생산할 수 있는 다른 이점이 있다.In addition, compared to the existing fermenter can be produced at a lower price, there is another advantage that can reduce the human, material management costs and mass production of food waste products.
