제습식 식품 건조기{Food Dryer By Dehumidify Type}Dehumidifying Food Dryer {Food Dryer By Dehumidify Type}

본 고안은 식품 건조기에 관한 것으로서, 특히 식품 건조시에 발생하는 수분을 제습하는 과정에서 비교적 저온을 유지하여 우량품질의 건조식품을 제공하기 위한 기술에 관한 것이다.The present invention relates to a food dryer, and more particularly, to a technique for providing a high quality dry food by maintaining a relatively low temperature in the process of dehumidifying the moisture generated during food drying.

그동안 식품을 건조하기 위하여, 수많은 방법의 건조기가 제공되어 왔다.In the meantime, in order to dry food, a number of methods have been provided.

보통은 열풍 순환방식을 택하여 저렴한 방식으로 식품을 건조 하여 왔으나, 건조온도를 비교적 높이 선정하여 식품의 품질을 저하 시켜 왔고,에너지 효율이 낮아 경제적 손실을 초래 하였다.Usually, food has been dried in a cheap way by using hot air circulation method, but the drying temperature has been selected relatively high, which has lowered the quality of food and caused economic loss due to low energy efficiency.

또한 진공 건조나 냉동 건조를 선택할 경우 건조 원가가 상승하여 경제적 손실을 초래 하였다.In addition, if the vacuum drying or freeze drying is selected, the drying cost is increased, resulting in economic losses.

본 고안은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 일반적인 열풍 건조기에서, 제습 시 건조실 내부의 고온의 공기를 배출하여 발생하는 에너지 손실을 방지하기 위하여, 건조실에서 외부로 배출되는 수증기를 저온으 로 응축하여 물로 방출하고 수증기에 포함된 기화열 540Kcal/L을 회수하여 다시 건조실로 유입 하도록 하여, 열 에너지 효율을 증대시키고 저온 건조를 제공 하는데 그 목적이 있다.The present invention is devised to solve the above problems of the prior art, in the general hot air dryer, in order to prevent energy loss caused by exhausting the high temperature air inside the drying chamber during dehumidification, steam discharged from the drying chamber to the outside It condenses at low temperature and releases it into water, and recovers 540 Kcal / L of vaporized heat contained in water vapor and flows it back into the drying chamber, thereby increasing thermal energy efficiency and providing low temperature drying.

상기 과제를 해결하기 위한 본 고안의 제습식 건조기는, 냉온 소자(펠티어 소자)에 전기를 공급하여 발생하는 양면의 온도차이를 이용하여, 건조실에서 배출되는 수증기를 냉면(COOL SIDE)으로 통과하면 수증기가 응축하여 물로 변하여 배출하도록하고, 상기 냉면을 통과하여 제습된 공가가 온면(HEAT SIDE)의 고온부분을 통과 하므로서 가열 되도록 하면, 건조실에서 증발한 수증기가 물로 변하여 배출되는 결과를 초래하여 수증기로 직접 배출시 발생하는 열 에너지(기화열)를 상당히 절약 하고 저온 건조를 실현하는 수단이 제공된다.The dehumidifying dryer of the present invention for solving the above problems, when the water vapor discharged from the drying chamber passes through the COOL SIDE by using the temperature difference of both sides generated by supplying electricity to the cold temperature element (Peltier element). Is condensed into water and discharged, and the cold air dehumidified by passing through the cold surface passes through the high temperature portion of the heat side (HEAT SIDE) to be heated, resulting in the water vapor evaporated from the drying chamber turns into water and discharged directly into water vapor. Means are provided for significantly saving the thermal energy (heat of vaporization) generated during the discharge and for achieving low temperature drying.

본 고안 에의한 제습식 건조기는 열풍 순환식 건조기에 비해 건조실의 습도와 온도가 낮아 식품의 품질이 상승하고, 기화열을 재 사용 하므로서 열 에너지를 절감하는 2중 효과가 있다.The dehumidifying dryer according to the present invention has a double effect of reducing the heat energy by increasing the quality of food and reducing the heat of vaporization by lowering the humidity and temperature of the drying chamber compared to the hot air circulation dryer.

이하 본 고안에 의한 제습식 건조기의 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, an embodiment of a dehumidifying dryer according to the present invention will be described in detail.

도 1은 본 고안에의한 중요한 구조의 계통을 표시한 단면 도 이다.1 is a cross-sectional view showing the system of the important structure according to the present invention.

본 고안 에의한 제습식 건조기는 건조 대상물(2)이 투입되는 건조실(1)을 구 비하고 건조실 외벽은 내부와 열차단을 시키기 위하여 단열 구조를 포함한다.The dehumidifying dryer according to the present invention has a drying chamber 1 into which a drying object 2 is put, and an outer wall of the drying chamber includes a heat insulating structure to allow an interior and a heat shield.

상기 건조실 에서 배출되는 공기는 공기 순환유로(3)를 통하여 제습실(4)로 유입되고, 제습실은 전기 에너지를 받은 냉온소자(5)에 의하여 저온 상태를 유지하므로, 상기에서 유입된 공기가 응축되어 수증기에 포함되어 있던 기화열을 방출하고 물로 변하게 된다.The air discharged from the drying chamber is introduced into the dehumidification chamber 4 through the air circulation passage 3, and the dehumidification chamber is kept at a low temperature by the cold / hot element 5 which has received electrical energy, so that the air introduced therein condenses. This releases the heat of vaporization contained in the vapor and turns it into water.

상기에서 발생한 물은 응축수 배출구(6)를 통하여 자연히 배출되고 상기에서 기화열을 방출한 공기는 제습 상태에서 공기 순환팬(7)을 통하여 열매체 히터(10)로 유입되고 상기 공기는 열매체 히터(10)에서 가열되어 건조한 공기가 되어 건조실(1)로 재 유입된다.Water generated in the above is naturally discharged through the condensate outlet (6) and the air discharged from the vaporization heat is introduced into the heat medium heater (10) through the air circulation fan (7) in the dehumidification state and the air is a heat medium heater (10) Is heated to become dry air and flows back into the drying chamber (1).

상기 건조한 공기는 건조 대상물(2)를 통과 하면서 건조 대상물에 함유된 수분을 흡수하여 상부로 상승하고 상부에 모인 습한 공기는 다시 공기 순환유로(3)을 통하여 제습실로 유입한다.The dry air is absorbed by the moisture contained in the object to be dried while passing through the object (2) to rise to the top, the wet air collected in the upper flows back into the dehumidification chamber through the air circulation passage (3).

한편 제습실(4)에서 냉온소자(5)의 냉면(Cooling Side)에 흡수한 열 에너지는 냉온소자의 히트펌프 작용에 의하여, 온면(Heating Side)에서 고온으로 방출하므로 온면에 구비된 방열 전열기(8) 에 상기 열 에너지가 흡수되고, 상기의 열 에너지는 열매체를 타고 열매체 펌프(9)의 순환작용으로 열매체 히터(10)로 유입되어 상기 공기 순환팬(7)의 작용으로 순환하는 공기에 열 에너지를 전달하여, 결과적으로 제습실 에서 흡수한 기화열 에너지를 재 사용하는 결과를 가저온다.On the other hand, the heat energy absorbed from the dehumidification chamber 4 to the cooling side of the cold / warm element 5 is discharged at a high temperature from the heating side by the heat pump action of the cold / warm element. 8) the heat energy is absorbed, and the heat energy is introduced into the heat medium heater 10 by the circulation action of the heat medium pump 9 through the heat medium and heat to the air circulated by the action of the air circulation fan 7. The energy is transferred, resulting in the reuse of the vaporized heat energy absorbed by the dehumidification chamber.

상기의 공기순환 싸이클과 열 순환 싸이클이 연속적으로 이루어 지면서, 건조 대상물(2)의 수분이 증발하여 열 에너지를 방출하고, 물로 변하여 응축수 방출 구(6)로 방출하는 결과를 이룩 하게된다.As the air circulation cycle and the heat circulation cycle are continuously performed, the moisture of the drying object 2 is evaporated to release thermal energy, and the water is converted into water and released to the condensate discharge port 6.

현재 사용되고 있는 열풍 순환 건조기 에서는 수증기가 직접 방출하므로, 방출수증기에 포함된 기화열을 직접 방출하여 열 에너지의 손실을 초래하여 왔다.In the hot air circulation dryer currently used, since water vapor is directly discharged, heat energy has been lost by directly releasing vaporization heat contained in the discharge steam.

또한 건조 대상물에 작용하는 공기가 열풍 순환건조기 에서는 다습한 상태를 유지하여 비교적 고온에서 증발이 가능하지만 본 고안에 의한 제습식 식품 건조기에서는, 작용하는 공기가 저습도 상태를 유지하므로 비교적 저온 건조가 가는한 장점이 있다.In addition, in the hot air circulation dryer, the air acting on the object to be dried can be evaporated at a relatively high temperature. However, in the dehumidifying food dryer according to the present invention, the air acts at a low humidity so that the drying is relatively low. There is one advantage.

도 1은 본 고안에의한 제습식 식품 건조기의 구성 계통을 나타낸 단면도.1 is a cross-sectional view showing a system of the dehumidifying food dryer according to the present invention.
