Description

농산물 건조기 {drying device of agricultural products} Drying device of agricultural products

본 발명은 간이 농산물 건조장치에 관한 것으로, 상세하게는 건조기의 내부를 진공시켜 농산물의 수분 추출이 용이하도록 하고 이로 인하여 면상 발열체로 단시간 내에 농산물을 건조할 수 있도록 할 뿐만 아니라 양질의 상태로 건조되도록 하는 농산물 건조장치에 관한 것이다.
The present invention relates to a simple agricultural product drying apparatus, and in particular, to vacuum the inside of the dryer to facilitate the extraction of water from the agricultural product, thereby allowing not only to dry the agricultural product in a short time with a surface heating element, but also to dry in a good state. It relates to a agricultural product drying apparatus.

일반적으로 고추, 콩, 버섯, 그리고 약재 등의 농산물은 장시간 보관되면서 이용되는 경우가 많은데, 수분의 함유로 농산물이 쉽게 부패하여 변질할 우려가 높아 이를 방지하기 위하여 햇볕에 말리거나 일정온도로 가열하여 건조한 후 보관하는 경우가 많다.In general, agricultural products such as red pepper, soybeans, mushrooms, and medicinal herbs are often used while being stored for a long time, and the contents of the food are easily decayed due to the moisture content. Often stored after drying.

더불어 농가에 생산되는 각종 곡물들은 장기간의 저장력을 향상시키거나 분말화하여 사용할 수 있고, 나아가 농수산물의 변질을 막기 위해 각종 농산물을 건조시켜 판매하거나 또는 장기간 보관하게 하였다.In addition, various grains produced in farms can be used to improve long-term storage capacity or to be powdered, and furthermore, to prevent the deterioration of agricultural and marine products, various agricultural products are dried or sold or stored for a long time.

이러한 농산물의 건조는 농가에서 야적지나 도로변에 돗자리를 깔고 각종 곡물을 펴 놓은 채 자연 건조하는 것이 대부분이다.Most of these agricultural products are naturally dried in farms and with mats on roadsides and roadsides.

하지만, 이렇게 외부에서 건조하면 각종 이물질이나 먼지가 농수산물에 많이 묻게 되고, 특히 비가 오는 날이나 아침 저녁으로 이슬을 맞기 전에 일일이 거둬 들여야 하는 불편이 따랐다.However, when dried from the outside, various foreign matters or dusts get on the agricultural and aquatic products, and it was inconvenient to collect every day before the dew on rainy days or morning and evening.

따라서, 우기 등 습한 날이나, 장마철에는 농수산물이 쉽게 썩을 수 있기 때문에 신속하게 말려 건조시켜야 함에 불구하고 대부분 그냥 방치할 수밖에 없는 문제점이 있었다.Therefore, in a wet day, such as the rainy season, during the rainy season, the agricultural and marine products can easily rot, but despite the need to dry quickly, most of them had to be left alone.

더욱이 농수산물 건조기로 건조하는 경우에는 농산물이 수납되는 일정크기의 건조기 본체에 전기나 기름, 또는 가스를 연료로 사용하는 히터를 설치하여 상기 히터에 의해 가열되는 공기로 농산물이 건조되도록 하는 것이 대부분이다.In addition, in the case of drying the agricultural and aquatic product dryers, a heater using electricity, oil, or gas as a fuel is installed in a dryer body of a certain size in which the agricultural products are stored, so that the agricultural products are dried by the air heated by the heater.

여기에, 상기 히터는 주로 건조기 본체의 하단에 설치되어 건조기 본체의 내부 공기를 가열하였는데, 이에 따라 가열된 공기가 하부에서 상부로 올라가면서 건조기 본체의 상하면 사이에 수납되어 있는 농수산물을 건조한 후 건조기 본체 상부에 형성된 공기 배출구로 유출되었다.Here, the heater is mainly installed at the bottom of the dryer main body to heat the internal air of the dryer main body, and as a result of drying the agricultural and marine products stored between the upper and lower sides of the dryer main body while the heated air rises from the lower part to the upper part of the dryer main body. It flowed out to the air outlet formed at the top.

그러나 종래의 건조기는 가열된 공기가 하부에서 상부로 대류하면서 농산물이 건조되도록 함으로써 건조기 본체에 수납된 농수산물 전체를 골고루 건조되는데에는 한계가 있을 뿐만 아니라 건조시간이 오래 걸리는 문제점이 발생하였다.
However, in the conventional dryer, the agricultural products are dried while the heated air is convection from the lower part to the upper part, thereby limiting the dryness of the entire agricultural product stored in the dryer body and having a long drying time.

따라서 상기한 문제점을 해결하기 위해 본 발명의 주목적은 외부 자연환경에 영향을 받지 않고 어느 때나 농산물을 진공 상태에서 면상 발열체를 이용하여 단시간 내에 건조할 수 있도록 하는 농산물 건조기를 제공하는 데 있다.Therefore, the main object of the present invention to solve the above problems is to provide a agricultural product dryer that can be dried in a short time by using a surface heating element in a vacuum at any time without being affected by the external natural environment.

본 발명의 농산물이 일정량 수납되는 건조기 본체의 내벽에 부착된 탄소 면상 발열체에 의해 건조기 본체의 내부 공기를 균일하게 골고루 가열함과 동시에 면상 발열체에서 방출하는 원적외선으로 농산물의 품질도 향상시켜 건조할 수 있도록 하는 농산물 건조기를 제공하는 데 있다.
The carbon flat heating element attached to the inner wall of the dryer main body in which the agricultural products of the present invention are stored in a certain amount evenly heats the internal air of the dryer main body evenly and at the same time improves the quality of the agricultural products by far infrared rays emitted from the flat heating element. To provide a agricultural product dryer.

이러한 목적을 달성하기 위하여 본 발명의 농산물 건조기는 본체의 전면에 개폐도어를 부착한 건조실과; 상기 건조실의 내면에 면상 발열체를 부착하여 균일하게 열을 조사하는 발열부와, 상기 건조실의 내부에 순차적으로 농산물을 안치한 트레이를 적층하여 면상 발열체로부터 원적외선과 열을 조사받아 농산물을 최상의 품질로 건조하는 선반부, 및 상기 건조실의 상부에 상향으로 설비실을 형성하고 설비실에 흡입펌프를 설치하며 흡입펌프에 흡입관을 결합하고 흡입관을 건조실에 연통시켜 내부공기를 펌핑하여 진공시키되, 건조실 내부의 온도와 진공 상태를 감지하는 온도감지센서와 진공감지센서를 설치하고 이를 센싱하여 면상 발열체와 흡입펌프를 제어하는 컨트롤박스를 설치한 진공부로 구성하되; 상기 건조실은 흡입펌프를 제어하여 60~65%의 진공상태를 지속적으로 유지하도록 함과 동시에 면상 발열체를 제어하여 65~70℃의 온도를 지속적으로 유지하도록 구성함을 그 기술적 구성상의 기본특징으로 한다.
In order to achieve this object, the agricultural product dryer of the present invention comprises a drying chamber having an opening and closing door attached to the front of the main body; The heat generating unit attaches a planar heating element to the inner surface of the drying chamber and uniformly irradiates heat, and stacks a tray in which agricultural products are sequentially placed inside the drying chamber to irradiate far infrared rays and heat from the planar heating element to dry the agricultural products in the best quality. The upper part of the shelf and the drying chamber is formed upward, the suction pump is installed in the equipment chamber, the suction pipe is coupled to the suction pump, and the suction pipe is connected to the drying chamber to pump internal air to be vacuumed. A vacuum unit having a temperature sensor and a vacuum sensor for detecting a vacuum state and a sensing box installed therein and a control box for controlling the surface heating element and the suction pump; The drying chamber is configured to maintain a vacuum of 60 to 65% by controlling the suction pump and to control the surface heating element to maintain a temperature of 65 to 70 ℃ as a basic feature of the technical configuration. .

따라서 상기한 본 발명의 농산물 건조기는 건조실의 진공상태를 60~65% 정도의 진공상태를 지속적으로 유지하도록 하고 온도를 65~70℃를 유지하도록 하는 것으로, 건조실의 내부를 적정하게 진공시켜 농작물에 함유된 수분의 배출을 신속하게 진행시키고 면상 발열체의 히팅으로 농작물이 골고루 신속하게 건조할 뿐만 아니라 원적외선의 조사로 인하여 양질의 건조상태를 유지하여 농산물을 최상의 품질로 건조하는 효과가 있는 것이다.Therefore, the agricultural product dryer of the present invention is to maintain the vacuum of about 60-65% of the vacuum state of the drying chamber and to maintain the temperature of 65 ~ 70 ℃, by appropriately vacuuming the interior of the drying chamber to the crops The rapid discharge of the water contained and the heating of the surface heating element not only to dry the crop evenly quickly, but also to maintain the high quality dry condition by the irradiation of far infrared rays, which is the effect of drying the produce to the best quality.

이하 첨부된 도면을 참조하면서 본 발명의 실시 예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 내지 도 4 에 나타낸 바와 같이, 본 발명의 농산물 건조기(1)는 본체(10)의 전면에 개폐도어(111)를 부착한 건조실(110)과, 상기 건조실(110)의 내면에 면상 발열체(121)를 부착하여 균일하게 열을 조사하는 발열부(120)와, 상기 건조실(110)의 내부에 순차적으로 농산물을 안치한 트레이(131)를 적층하여 면상 발열체(121)로부터 원적외선과 열을 조사받아 농산물을 최상의 품질로 건조시키는 선반부(130)와, 상기 건조실(110)의 내부공기를 외부로 펌핑하여 진공하는 진공부(140)로 구성한다.As shown in Figures 1 to 4, the agricultural product dryer 1 of the present invention is a drying chamber 110 having an opening and closing door 111 attached to the front of the main body 10, and a planar heating element on the inner surface of the drying chamber 110 A heat generating unit 120 attaching 121 and uniformly irradiating heat and a tray 131 in which agricultural products are sequentially placed inside the drying chamber 110 are stacked to irradiate far infrared rays and heat from the planar heating element 121. It consists of a shelf unit 130 for receiving the best quality of the agricultural products and the vacuum unit 140 for vacuuming the internal air of the drying chamber 110 to the outside.

상기 건조실(110)은 전면을 개구하여 개구부에 개폐도어(111)를 부착하되 잠금시 완전하게 밀폐되도록 한다.The drying chamber 110 opens the front surface to attach the opening and closing door 111 to the opening to be completely sealed when locked.

상기 발열부(120)는 면상 발열체(121)를 건조실(110)의 내벽에 부착하되 개폐도어(111)의 내부 측면에 추가로 부착할 수도 있다.The heat generating unit 120 may be attached to the inner surface of the opening and closing door 111, the surface heating element 121 is attached to the inner wall of the drying chamber 110.

여기서 면상 발열체(121)는 상지와 하지로 작업을 분리하여 어느 한 면 또는 양면에 발열소재를 도포한 후 충분하게 건조가 이루어지면 상지와 하지를 합지하는 과정에서 편조선이라 칭하는 동선을 순수 압출코팅방식(Extrude Laminating) 또는 접착제를 사용한 드라이 라미네이팅(Dry Laminating) 방식으로 견고하게 고정시켜 통전선으로 사용하는 것으로, 원적외선 시트 등이 결합된 다양한 면상 발열체(121)를 선택적으로 사용할 수 있다.Here, the surface heating element 121 is a pure extrusion coating of a copper wire called a braided wire in the process of laminating the upper and lower limbs after separating the work into the upper and lower limbs and applying a heating material to one or both sides, and then drying it sufficiently. By firmly fixing by using an Extrude Laminating method (Dry Laminating) method using an adhesive or by using a conductive wire, it is possible to selectively use a variety of planar heating element 121 combined with a far infrared sheet or the like.

상기 선반부(130)는 통상의 사각 트레이(131)를 사용함이 바람직하나 이를 한정하는 것은 아니며 건조실(110)의 좌우에 지지프레임(132)을 부착하여 트레이(131)가 상하로 일정간격을 유지시켜 면상 발열체(121)로부터 조사되는 열과 원적외선을 골고루 균일하게 조사되어 건조효율을 향상시키도록 함이 바람직하다.The shelf unit 130 preferably uses a conventional rectangular tray 131, but is not limited thereto, and the support frame 132 is attached to the left and right sides of the drying chamber 110 to maintain the tray 131 at regular intervals. It is preferable to improve the drying efficiency by uniformly irradiating heat and far infrared rays irradiated from the planar heating element 121.

상기 진공부(140)는 건조실(110)의 상부에 상향으로 설비실(146)을 형성하고 설비실(146)에 흡입펌프(141)를 설치하며 흡입펌프(141)에 흡입관(142)을 결합하되 흡입관(142)을 건조실(110)에 연통시켜 내부 공기를 펌핑하여 진공시킨다.The vacuum unit 140 forms a facility chamber 146 upward on the drying chamber 110, installs a suction pump 141 in the facility chamber 146, and couples the suction pipe 142 to the suction pump 141. However, the suction pipe 142 is communicated with the drying chamber 110 to pump the internal air to vacuum.

여기서 설비실(146)에는 건조실(110) 내부의 온도와 진공 상태를 감지하는 온도감지센서(143)와 진공감지센서(144)를 설치하고 이를 센싱하여 면상 발열체(121)와 흡입펌프(141)를 제어하는 컨트롤박스(145)를 설치한다.Here, in the equipment room 146, a temperature sensor 143 and a vacuum sensor 144 for detecting a temperature and a vacuum state inside the drying chamber 110 are installed and sensed to detect the surface heating element 121 and the suction pump 141. Install the control box 145 to control.

이러한 본 발명은 농산물을 골고루 펴 트레이(131)에 안치하여 건조실(110)에 순차적으로 일정간격을 유지하면서 적층한다.The present invention evenly spreads the agricultural products are placed in the tray 131 and laminated in a drying chamber 110 while maintaining a predetermined interval in sequence.

여기서 개폐도어(111)를 닫아 건조실(110)을 밀폐시긴 후 컨트롤 박스(145)를 조작하여 흡입펌프(141)를 구동함과 동시에 면상 발열체(121)를 "온" 시켜 농작물을 건조시킨다.Here, the opening and closing door 111 is closed to seal the drying chamber 110, and then the control box 145 is operated to drive the suction pump 141 and at the same time turn on the planar heating element 121 to dry the crop.

이때 흡입펌프(141)의 구동으로 건조실(110)의 공기가 흡입관(142)을 통해 외부로 펌핑되고 이로 인하여 건조실(110)은 진공상태를 유지하게 되는 데, 건조실(110)의 진공상태를 진공감지센서(144)가 센싱하여 60~65% 정도의 진공상태를 지속적으로 유지하도록 한다.At this time, the air of the drying chamber 110 is pumped to the outside through the suction pipe 142 by the driving of the suction pump 141, whereby the drying chamber 110 is maintained in a vacuum state, the vacuum of the drying chamber 110 is vacuum The sensing sensor 144 senses to maintain a vacuum of about 60 ~ 65%.

이와 동시에 면상 발열체(121)의 동작으로 건조실(110)의 내부가 히팅하게 되고 이로 인하여 농작물이 건조되기 시작하게 되는 데, 건조실의 온도는 65~70℃가 적당하다.At the same time, the interior of the drying chamber 110 is heated by the operation of the planar heating element 121, and thus, the crops start to dry, and the temperature of the drying chamber is preferably 65 to 70 ° C.

특히 건조실(110)의 내부를 적정하게 진공시킴으로써 농작물에 함유된 수분의 배출이 빨라지고 면상 발열체(121)의 히팅으로 농작물이 골고루 신속하게 건조 될 뿐만 아니라 원적외선의 조사로 인하여 양질의 건조상태를 유지할 수 있는 것이다.In particular, by properly evacuating the interior of the drying chamber 110, the discharge of moisture contained in the crops is accelerated, and the crops are dried quickly and quickly by heating of the surface heating element 121, and the quality of the dry state can be maintained due to the irradiation of far infrared rays. It is.

예를 들어, 고추의 경우 히터로 통상의 단순 건조하는 경우에는 대략 72시간 정도 걸리게 되는 데, 건조실(110)을 65%의 진공상태를 유지하면서 면상 발열체(121)를 이용하여 68℃로 히팅하면서 원적외선을 조사하는 경우에는 24시간 정도가 지나면 수분 함유량 5% 정도인 최상의 고추를 건조하여 최상의 품질로 유지하도록 하는 것이다.
For example, in the case of red pepper, it takes about 72 hours in the case of ordinary simple drying with a heater, while heating the drying chamber 110 to 68 ° C. using the planar heating element 121 while maintaining a vacuum of 65%. In the case of irradiating far-infrared, after 24 hours, the best pepper with 5% moisture content is dried to maintain the best quality.
