It does not need turn the food product being dried upside down, saves energy costs and reduces man power. The food drier consists of: a transparent window frame(27-1) containing a leg(29,29-1), a heated air dispersion plate(20), a grid(21), a food product(22) being dried and a transparent window(23); an exhaust pipe(25) for exhausting heated air(33) and a drier(27) containing an insect net; and a solar collector(15) containing a heat collecting transparent window(13), a heat-absorbing plate(14) and an incoming air control valve(12). In the food drier, solar energy is collected by introducing heated air which is heated by solar heat in the solar collector into the drier.

Description

태양열 식품 건조기{FOOD DRYER USING THE SUNLIGHT}Solar Food Dryer {FOOD DRYER USING THE SUNLIGHT}

본 발명은 태양열에 의해 식품을 건조하는 방법에 관한 것으로 옥외에 식품을 널어 놓고 태양열과 바람에 의해서 수분을 증발시켜 건조하는 방법과 대량의 에너지가 필요한 열풍 건조 방법이거나 태양열을 일부분만 활용하는 (발명특허 10-0105117/1996. 09. 21) 방법 등이 있으나 옥외 건조는 비위생적이고, 날씨에 좌우되고, 옥외에 널거나 거두어 들일 때 많은 일손이 필요하며 넓은 장소를 확보해야한다. 열풍건조 방식은 대량의 에너지가 필요하며 건조식품의 질은 태양열에 의한 자연 건조에는 못 미치는 결함이 있으며 발명특허 10-0105117 방법은 건조실 상부의 면적만큼만 태양열을 활용하는 방법 등이 있다.The present invention relates to a method of drying foods by solar heat and to drying foods outdoors and drying by evaporating moisture by solar heat and wind, and a hot air drying method requiring a large amount of energy or utilizing only part of solar heat (invention). Patent 10-0105117 / 1996. 09. 21) There is a method, but the outdoor drying is unsanitary, depending on the weather, a lot of hands are required when you are outdoors or harvested, you need to secure a large place. Hot air drying method requires a large amount of energy and the quality of the dried food has a defect that is less than the natural drying by solar heat, and the invention patent 10-0105117 method has a method of utilizing the solar heat as much as the area of the upper drying chamber.

따라서 본 발명은 자연상태에서 건조물 상부 표면에 작용하는 태양에너지는 극히 옅으므로 태양열 집열기를 이용하여 공기를 1차 가열하여 그 가열공기를 이용, 건조기 내부와 건조물 하부 표면을 가열하며 온도를 상승시키고 건조물 상부에 2차 태양광을 직사시키므로 건조물과 건조기 내부의 온도를 더욱 상승시켜 공기의 흐름이 발생하면서 수분이 증발하기 좋은 조건으로 만드는 구조를 제공함에 있다.Therefore, according to the present invention, the solar energy acting on the upper surface of the building in the natural state is extremely thin, so the air is first heated by using a solar collector and the heating air is used to heat the inside of the dryer and the lower surface of the building, raising the temperature and drying the building. Directly directing the secondary solar light on the upper side to further increase the temperature inside the drying and drying machine to provide a structure that makes the conditions for the evaporation of moisture while the air flow occurs.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다. 도 1은 본 발명의 전체적인 구성을 보인 것이며, 도 2에서 도시된 바와 같이 지상바닥 기초(30)에 고정된 다리(29, 29-1) 위에 가열 공기 분배판(20) 격자(21) 식품건조물(22)을 내장하고 힌지(24)에 의해 열고 닫을 수 있는 투명창(23)으로 된 투명창틀(27-1)과 가열공기(32)를 배출할 수 있는 배기파이프(25) 방충망(26)이 부착된 건조기(27)가 남쪽 방향 또는 일조량이 많은 방향으로 설치되고 집열투명창(13) 흡열판(14) 유입공기 조절밸브(12) 공기필터(11)로 구성된 집열기(15)는 태양광(17)과 직각에 가깝게 설치하고 집열기(15)와 건조기(27)를 파이프(16)로 연결하여 구성한다.Hereinafter, described in detail by the accompanying drawings as follows. Figure 1 shows the overall configuration of the present invention, the heating air distribution plate 20 grid 21 food drying on the legs 29, 29-1 fixed to the ground floor foundation 30 as shown in FIG. A transparent window frame 27-1 having a transparent window 23 which can be opened and closed by a hinge 24 and an exhaust pipe 25 capable of discharging heating air 32, and a insect screen 26 The attached dryer (27) is installed in the south direction or in the direction of a large amount of sunlight, and the heat collector (15) composed of the heat collecting transparent window (13), the heat absorbing plate (14), the inlet air control valve (12), and the air filter (11). It is installed close to (17) at right angles and is configured by connecting the collector (15) and the dryer (27) with a pipe (16).

유입공기(31)가 공기필터(11)를 거쳐 과열방지를 위한 공기량 조절 밸브(12)를 통과하여 집열기(15) 내부로 유입되고 태양광(17)에 의해 흡열판(14)이 가열되면 내부 공기도 가열되며 가열공기가(32)가 열대류 현상에 의해 상승하여 집열기(15) 상부의 파이프(16)를 통과하여 건조기(27) 하부로 유입된다. 가열공기(32)는 가열공기 분배판(20)을 거쳐 분산되며 상승한다. 건조기(27) 내에 내장된 격자(21) 위에 식품건조물(22) 하부 표면을 가열하고 건조기(27) 내부 온도를 상승하여 수분을 증발시키며 건조기(27) 상부 투명창(23)을 통하여 유입된 태양광(17)은 식품건조물(22)의 상부 표면을 더욱 가열하고 표면의 수분을 증발시킨다. 증발된 수분을 함유한 가열공기(32)는 배기파이프(25)를 통하여 굴뚝효과에 의해 외부로 배출된다.When the inlet air 31 passes through the air filter 11 and passes through the air volume control valve 12 to prevent overheating, the inlet air 31 enters the collector 15 and the heat absorbing plate 14 is heated by the sunlight 17. The air is also heated and the heated air 32 rises due to a tropical flow phenomenon and passes through the pipe 16 above the collector 15 and flows into the dryer 27. The heated air 32 is dispersed and raised via the heated air distribution plate 20. Heating the lower surface of the food product 22 on the lattice 21 embedded in the dryer 27 and raising the temperature of the dryer 27 to evaporate moisture and entering the sun through the upper transparent window 23 of the dryer 27. The light 17 further heats the upper surface of the food product 22 and evaporates moisture on the surface. The heated air 32 containing the evaporated water is discharged to the outside by the chimney effect through the exhaust pipe 25.

이상 태양광(17)에 의해 유입공기(31) 가열공기(32) 배출공기(33)의 흐름이 계속되면 건조기(27) 내부의 식품건조물(22)은 자연상태의 건조보다 저온 살균되며 용이하게 빨리 건조된다.When the flow of the inlet air 31, the heating air 32, and the exhaust air 33 continues by the sunlight 17, the food building 22 inside the dryer 27 is pasteurized more easily than the drying in the natural state. Dries quickly.

이상과 같이 본 발명은 태양열을 이용하므로 에너지 비용이 전혀 필요 없고, 날씨 변화, 밤낮에 따라 건조물을 펼치고 거두어 들이는 일손이 필요 없으며, 청결한 상태에서 저온 살균되면서 건조물 상, 하부 표면에 고루 건조되므로 건조물을 뒤집는 일손이 필요없으며 질 좋은 태양 건조 식품을 만들 수 있는 건조기임.As described above, the present invention does not require any energy costs because it uses solar heat, and does not need to expand and reap dry matters according to weather changes, day and night, and dry the pastes on the bottom and the bottom surface while being pasteurized in a clean state. It is a dryer that can make quality sun-dried food without the need of flipping hands.
