커피생두 로스팅장치{GREEN COFFEE BEANS ROASTING MACHINE }Green coffee bean roasting device {GREEN COFFEE BEANS ROASTING MACHINE}

본 발명은 커피생두 로스팅장치에 관한 것으로, 더욱 상세하게는 커피생두를 찐 후에 동결건조하여 가공하고, 이를 특수한 형태의 로스팅장치에 넣어서 로스팅할 수 있도록 함으로써, 커피의 향을 그대로 보관함과 동시에 로스팅시간을 현저히 줄임으로써 로스팅 후에 산폐를 막아서 커피의 향과 맛을 더욱 좋게 할 수 있도록 한 커피생두 로스팅장치에 관한 것이다.The present invention relates to a roasting device for green coffee beans. More specifically, the present invention relates to a roasting device for green coffee beans, which processes green coffee beans by steaming them, freeze-drying them, and roasting them by placing them in a special type of roasting device, thereby preserving the aroma of the coffee and reducing the roasting time. This relates to a green coffee bean roasting device that significantly reduces the coffee bean aroma and taste by preventing rancidity after roasting.

일반적으로 커피 로스터기는 주로 로스팅 방식에 따라 직접가열(directly heated drum) 방식인 직화식로스터기, 간접 가열(indirectly heated drum)방식인 열풍식 로스터기, 그리고 대류와 전도열을 사용하는 반열풍식 로스터기로 분류할 수 있다. In general, coffee roasters are mainly classified according to the roasting method into direct fire roasters using a directly heated drum method, hot air roasters using an indirect heated drum method, and semi-heated wind roasters using convection and conduction heat. can do.

이러한 로스터기의 구조는 하드웨어적으로 고정되어 있으면 로스팅 방법을 변경 시 구조나 드럼 자체를 바꿔야 한다.If the structure of this roaster is fixed in terms of hardware, when changing the roasting method, the structure or the drum itself must be changed.

각각의 주요 로스팅 방식에 대한 특징으로, 직접가열(directly heated drum) 방식인 직화식은 드럼에 구멍을 내어 열원의 불꽃이 드럼의 구멍 통로를 통해 직접 커피콩에 닿게 하는 방식인데 커피 맛은 뛰어나지만 커피 콩의 팽창이 작고 열원에 타기 쉽고 균일한 로스팅이 어려운 단점이 있다.The characteristic of each major roasting method is that the direct heating method, which is a directly heated drum method, is a method in which a hole is made in the drum and the flame of the heat source reaches the coffee beans directly through the hole passage in the drum. The disadvantage is that beans do not expand easily, are easily burned by heat sources, and are difficult to roast evenly.

간접 가열(indirectly heated drum)방식인 열풍식은 열원이 드럼을 직접 가열하지 않고 별도의 연소실에서 열풍이 만들어지고 이 열풍은 드럼 끝단의 열풍 구멍을 통하여 드럼안으로 대류 시켜 로스팅하는 방식이다. In the hot air method, which is an indirectly heated drum method, the heat source does not directly heat the drum, but hot air is created in a separate combustion chamber, and this hot air is convected into the drum through the hot air hole at the end of the drum for roasting.

드럼 내부의 예열 시간이 가장 길고 원하는 커피 스타일을 만들기 가장 어려운 방식이다.This method requires the longest preheating time inside the drum and is the most difficult to produce the desired coffee style.

반열풍식은 드럼에 직접 열을 가하고 드럼 열풍 구멍으로 뜨거운 열풍을 통과시켜 대류와 전도열을 둘 다 사용하는 방식으로 로스팅 결과가 균일하고 열손실이 적어 커피 콩의 팽창이 크다. 즉 원두의 손실이 적다. The semi-hot air method uses both convection and conductive heat by applying heat directly to the drum and passing hot air through the drum hot air hole. The roasting result is uniform, heat loss is low, and coffee beans expand greatly. In other words, there is little loss of coffee beans.

하지만 단점으로 드럼 내부 예열 시간이 직화 방식에 비해 길고 고온으로 로스팅 시 풋풋한 향이 날 수 있다. However, the disadvantage is that the preheating time inside the drum is longer than that of the direct fire method, and a fresh scent may be produced when roasting at high temperatures.

그러나, 로스터기 분류는 위의 3가지 이외에도 변형된 형태가 많이 존재한다. 이러한 종래의 로스터기는 하드웨어적으로 고정된 어느 한 방식으로 설정되어 있음으로 다른 로스팅 방식으로 변경하는 것이 어려워서 다른 방식의 로스팅기를 필요로 하는 경우에는 추가로 구매하여야 하므로 비용이 증가하는 문제점이 있다.However, there are many modified forms of roaster classification other than the three above. Since these conventional roasters are set in one fixed hardware method, it is difficult to change to a different roasting method, so if a roaster of a different method is required, an additional roaster must be purchased, which increases costs.

또한, 로스팅은 상기한 어느 한 방식에 의하여 진행되므로 복합적인 컴비네이션 타입의 커피 맛을 구현하기 어려운 문제점이 있다.In addition, since roasting is performed using one of the above methods, there is a problem in that it is difficult to realize a complex combination type of coffee taste.

상기한 문제점을 해결하기 위해서, 대한민국 특허청 등록특허공보 제1861606호에는 가변형 커피로스팅 장치가 개시된 바 있다.In order to solve the above problems, a variable coffee roasting device has been disclosed in Korean Patent Office Registered Patent Publication No. 1861606.

최근 들어 스페셜티 커피(Specialty coffee), 루왁 커피(Luwak coffee), 블랙 아이보리 커피(black ivorycoffee) 등 고급의 특수 커피가 부각되고 있다. 이들 중 사향 고양이가 먹고 배설한 것으로부터 얻는 루왁 커피와 코끼리가 먹고 배설한 것으로부터 얻는 블랙 아이보리 커피는 일종의 발효 커피이다. 특히, 블랙 아이보리 커피의 경우, 약 1Kg의 커피콩을 얻기 위해 코끼리에게 약 33Kg의 커피 체리를 먹여야 하는 것으로 알려져 있고, 가격도 일반 커피에 비해 월등히 비싸다.Recently, high-quality specialty coffees such as specialty coffee, Luwak coffee, and black ivorycoffee have been highlighted. Among these, Luwak coffee, obtained from the food and excretion of civet cats, and Black Ivory coffee, obtained from the food and excretion of elephants, are types of fermented coffee. In particular, in the case of black ivory coffee, it is known that about 33 kg of coffee cherries must be fed to an elephant to obtain about 1 kg of coffee beans, and the price is much more expensive than regular coffee.

위와 같은 발효 커피는 커피생두가 동물의 소화기관을 거치면서 쓴 맛을 내는 단백질의 분해로 부드럽고 특유의 향미를 지니게 되는 것으로 알려져 있고, 또한, 항산화 물질인 폴리페놀과 클로로겐산의 수치가 일반 커피에 비해 높은 것으로 밝혀지고 있다. 그러나 이러한 동물을 이용하여 커피를 얻는 방식은 동물 학대의 가능성으로 인해 동물 보호단체로부터 반감을 사고 있다.The above-mentioned fermented coffee is known to have a soft and unique flavor due to the decomposition of proteins that produce a bitter taste as green coffee beans pass through the animal's digestive system. In addition, the levels of polyphenols and chlorogenic acid, which are antioxidant substances, are higher than those of regular coffee. It turns out to be high. However, this method of using animals to obtain coffee is opposed by animal protection groups due to the possibility of animal abuse.

동물을 이용하지 않고 대나무를 이용한 것으로, 『대나무잎 및 죽순 중에서 선택된 원료의 발효액에 볶은 커피를 침지하고 건져내어 물기를 제거한 다음 40 내지 50℃에서 2 내지 4일간 발효하는 발효커피 제조방법』이 등록번호 10-1807960(발명의 명칭: 발효커피의 제조방법, 발명자: 조영동)의 등록특허공보에 개시되어 있다.Registered as a “fermented coffee manufacturing method that involves immersing roasted coffee in a fermentation broth of raw materials selected from bamboo leaves and bamboo shoots, taking it out, removing moisture, and then fermenting at 40 to 50°C for 2 to 4 days,” using bamboo instead of animals, registered. It is disclosed in the Registered Patent Publication No. 10-1807960 (Title of the invention: Method for producing fermented coffee, Inventor: Young-dong Jo).

그러나, 종래의 커피생두의 가공방법, 로스팅 방법은 다음과 같은 문제점이 잇었다. However, the conventional processing and roasting methods of green coffee beans had the following problems.

(1) 커피생두를 가공할 때 씻어서 로스팅을 곧바로 하기 때문에 로스팅 시간이 매우 오래 걸린다. (1) When processing green coffee beans, they are washed and roasted immediately, so the roasting time takes a very long time.

(2) 로스팅 후에 가스의 분출과 수분의 적정한 침투를 위해서 숙성을 하게 되는데, 로스팅 후 부터 산패(rancidity)되기 시작하여 커피의 향과 맛을 떨어뜨린다.(2) After roasting, it is aged to allow gas to escape and moisture to penetrate properly. After roasting, the coffee begins to turn rancid, deteriorating the aroma and taste of the coffee.

(3) 로스팅하여 탄맛이 많이 나서 신맛이 많이 증가한다.(3) Roasting creates a burnt taste, which increases the sourness.

상기한 문제점을 해결하기 위해서, 본 발명의 커피생두의 로스팅방법은 커피생두를 씻는 세척단계와; 세척한 커피생두를 찌는 찜단계와; 상기 찐 생두를 동결건조하여 분쇄하여 커피생두분말을 형성하는 분쇄단계와; 상기 분쇄단계 후에 가공된 커피생두분말을 토터리식 로스팅기로 로스팅하여 포장하는 완성단계로 구성되는 것을 특징으로 한다. In order to solve the above problems, the roasting method of green coffee beans of the present invention includes a washing step of washing green coffee beans; A steaming step of steaming the washed green coffee beans; A grinding step of freeze-drying and grinding the steamed green coffee beans to form green coffee bean powder; It is characterized in that it consists of a completion step of roasting and packaging the processed green coffee bean powder in a tottery type roaster after the grinding step.

본 발명의 로스팅장치는 커피생두분말을 포함하는 호퍼와;The roasting device of the present invention includes a hopper containing green coffee bean powder;

상기 호퍼의 하단에 모터에 의해서 회전하는 공급스크류를 포함한 공급기와;a feeder including a feed screw rotated by a motor at the bottom of the hopper;

상기 공급기의 끝단에 연결되고, 내부에 공급스크류가 연장되어 포함되고, 외부에는 열을 공급하는 전열선이 형성되는 로스팅관과;a roasting tube connected to the end of the feeder, including an extended supply screw inside, and a heating wire supplying heat formed on the outside;

상기 로스팅과의 끝단에 로스팅된 커피가루가 포장되는 포장기로 구성되는 것을 특징으로 한다.It is characterized in that it consists of a packaging machine in which the roasted coffee powder is packaged at the end of the roasting unit.

본 발명의 바람직한 실시예로 형성된 커피생두 로스팅장치에 의하면 다음과 같은 효과가 발생한다.According to the green coffee bean roasting device formed according to a preferred embodiment of the present invention, the following effects occur.

(1) 커피생두를 동결건조하고 분쇄하여 커피생두분말을 로스팅하기 때문에 로스팅이 매우 빠른 속도로 이루어진다.(1) Because green coffee beans are freeze-dried, ground, and roasted to produce green coffee bean powder, roasting takes place at a very high speed.

(2) 로스팅한 후에 곧바로 커피를 내려서 먹을 수 있기 때문에 커피의 향을 그대로 포함할 수 있다.(2) Since the coffee can be brewed and consumed immediately after roasting, the aroma of the coffee can be retained.

(3) 로스팅시간이 짧기 때문에 커피생두가 타지 않게 로스팅되기 때문에 신맛이 현저히 줄어들고 커피 본연의 맛이 증가한다.(3) Because the roasting time is short, the coffee beans are roasted without burning, so the sourness is significantly reduced and the original taste of the coffee increases.
