Description

건조기{Drying apparatus}Drying apparatus {Drying apparatus}

본 발명은, 건조기에 관한 것으로서, 보다 상세하게는, 히트펌프를 이용하여 건조기를 구성함으로써 에너지 낭비를 줄이고 건조물에 따른 건조 부하 및 외기 온/습도 조절에 따라 최적의 사이클로 운전할 수 있는 건조기에 관한 것이다.The present invention relates to a dryer, and more particularly, to a dryer that can be operated at an optimal cycle according to a drying load and external air temperature / humidity control according to a dry matter by configuring a dryer using a heat pump. .

일반적으로 농산물 등을 건조시키기 위한 방법으로는 일광에 의한 자연건조와 기계적인 건조장치에 의한 강제건조로 대별된다.In general, methods for drying agricultural products are roughly classified into natural drying by daylight and forced drying by a mechanical drying device.

근래에 들어 일반적으로 실시되는 강제건조는 다소 구성의 차이는 있으나 발열수단을 구비한 건조로 내에서 열풍을 대류시켜 건조물에 포함되어 있는 수분이 열풍에 의해 증발되도록 함으로써 완성된 건조 농산물을 얻는 방법 및 장치가 사용되고 있다.In recent years, the forced drying generally carried out has a somewhat different configuration, but convection hot air in a drying furnace equipped with a heating means to obtain evaporated moisture by the hot air, thereby obtaining a dried product. The device is in use.

도 2는 종래 건조기의 개략적 단면도에 관한 것이다. 이 도면에서 볼 수 있는 바와 같이 종래의 건조기(70)는 연료를 연소시켜 열량을 발생하는 보일러(71)와, 보일러의 상부에 설치된 열교환기(73)와, 건조물을 건조하는 건조실(75), 그리고 유동을 형성시키는 팬(77)의 구성을 채용하고 있다.2 is a schematic cross-sectional view of a conventional dryer. As can be seen in this figure, the conventional dryer 70 includes a boiler 71 for burning heat to generate heat, a heat exchanger 73 installed at an upper portion of the boiler, a drying chamber 75 for drying a dry matter, And the structure of the fan 77 which forms a flow is employ | adopted.

이와 같은 건조기는, 보일러로 흡입된 공기는 연소열을 흡수하여 고온의 상태로 열교환기로 유출된다. 팬에 의해 외부의 저온공기가 열교환기로 유입되어 열교환기내의 고온의 공기와 열교환되어 온도가 상승함으로써 상대습도가 낮아져서 건조실내로 유입된다.In such a dryer, the air sucked into the boiler absorbs the heat of combustion and flows out to the heat exchanger in a high temperature state. External low temperature air flows into the heat exchanger by the fan, and heat exchanges with the high temperature air in the heat exchanger to increase the temperature, thereby lowering the relative humidity and entering the drying chamber.

상대습도가 낮은 유입공기는 건조실내의 건조물의 습기를 흡수하여 외부로 배출함으로써 건조가 이루어진다.Inflow air with low relative humidity is dried by absorbing moisture from the dry matter in the drying chamber and discharging it to the outside.

그런데, 상기와 같은 종래의 건조기는, 보일러에서 가열된 공기와 외부에서 유입된 공기의 열교환이 충분하지 않아 가열된 공기가 높은 온도로 연통을 통해 배출됨으로써 상당한 량의 열에너지가 손실되며 건조실 출구에서도 고온, 다습인 고 에너지의 공기가 외부로 방출됨으로써 에너지손실을 피할 수 없는 단점이 있다.However, in the conventional dryer as described above, since the heat exchange between the air heated in the boiler and the air introduced from the outside is not sufficient, the heated air is discharged through the communication at a high temperature, so that a considerable amount of thermal energy is lost and the high temperature even at the exit of the drying chamber. In addition, the high energy air of high humidity is released to the outside, there is a disadvantage that the energy loss is inevitable.

따라서, 본 발명의 목적은, 건조후 배출되는 고온, 다습의 공기를 증발기에 통과시킴으로써 배열 회수에 의해 건조기의 효율향상을 도모하며 공기 배출부와 흡입부 사이에 덕트를 구성하고 덕트내에 댐퍼를 설치하여 외기 온/습도 조건에 따라 순환되는 공기량을 조절함으로써 최적의 건조효율을 구현할 수 있는 건조기를 제공하는 것이다.Therefore, an object of the present invention is to improve the efficiency of the dryer by recovering the heat by passing the hot and humid air discharged after drying by the evaporator, forming a duct between the air discharge part and the suction part, and installing a damper in the duct. It is to provide a dryer that can implement the optimum drying efficiency by adjusting the amount of air circulated according to the outdoor temperature / humidity conditions.

상기 목적은, 본 발명에 따라, 건조실을 갖는 건조기에 있어서, 상기 건조기의 외부에 설치되어 냉매량을 조절하는 보조응축기와; 상기 건조기의 전면에 설치되며 흡입공기와 열교환을 수행하는 응축기와; 상기 응축기의 후면에 설치되며 다수의 토출구를 갖고 유속분포를 균일하게 하는 패널과; 상기 건조실 내부 후방에 설치되어 상기 건조실내의 습기를 흡수한 고온 다습의 공기를 통과시키는 증발기를 포함하며, 상기 증발기의 후면에 설치된 팬과: 상기 건조실의 외측 상면에 설치되어 유량의 유출/입을 안내하는 덕트를 포함하는 것을 특징으로 하는 건조기에 의하여 달성된다.According to the present invention, there is provided a dryer having a drying chamber, comprising: an auxiliary condenser installed outside the dryer to adjust a refrigerant amount; A condenser installed at the front of the dryer and performing heat exchange with suction air; A panel installed at the rear side of the condenser and having a plurality of discharge ports to uniform the flow rate distribution; And an evaporator installed at the rear of the drying chamber to pass high temperature and high humidity air absorbing moisture in the drying chamber, and a fan installed at the rear of the evaporator: installed at an outer upper surface of the drying chamber to guide the flow / out of the flow rate. It is achieved by a dryer characterized in that it comprises a duct.

여기서, 상기 덕트의 내부에는 외기 온/습도에 따라 유입유량 및 순환유량을 조절하는 흡입댐퍼, 토출댐퍼, 중간댐퍼가 설치되어 있는 것이 바람직하다.Here, the inside of the duct is preferably provided with a suction damper, a discharge damper, an intermediate damper for adjusting the inflow flow rate and the circulation flow rate according to the outside temperature / humidity.

이하에서는 첨부된 도면을 참조하여 본 발명에 대하여 상세히 설명한다. 도 1은 본 발명에 따른 건조기의 내부구성을 보인 단면도에 관한 것으로서, 이 도면에서 볼 수 있는 바와 같이 본 발명에 따른 건조기(10)는, 냉매량을 조절함으로써 건조실(13) 내부의 온도제어가 가능하여 건조물에 따라 건조온도의 조절이 가능토록 건조기의 외부에 보조응축기(11)를 설치하고 있다.Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention. 1 is a cross-sectional view showing the internal configuration of a dryer according to the present invention, as can be seen in this figure, the dryer 10 according to the present invention, the temperature control in the drying chamber 13 can be controlled by adjusting the amount of refrigerant. Therefore, the auxiliary condenser 11 is installed outside of the dryer so that the drying temperature can be adjusted according to the dry matter.

그리고, 건조실(13)의 전면에는 응축기(15)를 배치하여 흡입공기와 효율적인 열교환을 수행하여 흡입공기의 온도를 상승시킨다.Then, the condenser 15 is disposed on the front surface of the drying chamber 13 to perform efficient heat exchange with the intake air, thereby increasing the temperature of the intake air.

응축기(15) 후면에는 다수의 토출구(17)가 형성된 패널(19)을 부착하여 건조실(13)내의 균일한 공기가 흡입되게 하며, 건조실(13) 내부 후면에는 증발기(20)를 설치한다. 따라서, 건조물을 통과하여 습도가 높아진 공기를 증발기(20)를 통과시켜 배열을 현열 및 잠열의 형태로 회수하여 히트펌프사이클의 성능계수를 3이상으로 유지할 수 있다.A panel 19 having a plurality of discharge ports 17 is attached to the rear surface of the condenser 15 to allow uniform air in the drying chamber 13 to be sucked, and an evaporator 20 is installed at the rear surface of the drying chamber 13. Therefore, the air having a high humidity through the dry matter is passed through the evaporator 20 to recover the arrangement in the form of sensible and latent heat, thereby maintaining the performance coefficient of the heat pump cycle to 3 or more.

또한, 건조기(10)의 외측 상부면에 덕트(30)를 설치하고 덕트내에 흡입댐퍼(31)와 토출댐퍼(33), 그리고 중간댐퍼(35)를 설치하고 온도 등을 감지하는 감지기(도시치 않음)를 설치하여 적절히 제어함으로써 유입유량 및 순환유량을 조절하여 최적의 건조공정이 이루어지도록 제어한다.In addition, a detector for installing a duct 30 on the outer upper surface of the dryer 10, and installing a suction damper 31, a discharge damper 33, and an intermediate damper 35 in the duct and detecting a temperature or the like (not shown) By controlling the inlet flow rate and circulation flow rate by installing the proper control, the optimum drying process is controlled.

여기서, 각 댐퍼의 조절은 건조기(10) 및 덕트(30)에 설치되어 유입유량 및 순환유량을 감지하는 감지기와 연결된 제어부(도시치 않음)에 의해 자동조절 할 수 있다.Here, the adjustment of each damper may be automatically adjusted by a control unit (not shown) connected to a detector installed in the dryer 10 and the duct 30 to detect the inflow flow rate and the circulation flow rate.

이와 같은 구성에 따라 증발기(20) 후면의 팬(21)에 의해 흡입된 공기는 응축기(15)를 통과하여 온도가 상승하고 전면에 설치된 패널(19)을 거쳐 균일하게 건조실(13)내로 유입되어 건조공정을 수행한다.According to this configuration, the air sucked by the fan 21 at the rear of the evaporator 20 rises in temperature through the condenser 15 and is uniformly introduced into the drying chamber 13 through the panel 19 installed at the front. Perform the drying process.

건조공정을 수행한 공기는 증발기(20)를 통과함으로써 가지고 있던 열에너지를 사이클에 배출하게된다.The air that has undergone the drying process passes through the evaporator 20 to discharge the thermal energy it had in the cycle.

한편, 닥트(30) 내부에 설치된 토출댐퍼(33)의 개폐정도에 따라 배출량이 결정되고 배출되지 않은 공기는 다시 건조실(13)의 상면에 설치된 닥트(30)를 통과하여 순환하게 되며 중간댐퍼(35)의 개폐정도에 따라 응축기로 흡입되는 유량의 조절도 가능하게 된다.On the other hand, the discharge amount is determined according to the degree of opening and closing of the discharge damper 33 installed in the duct 30, the air not discharged is circulated again through the duct 30 installed on the upper surface of the drying chamber 13 and the intermediate damper ( It is also possible to adjust the flow rate sucked into the condenser according to the opening and closing degree of 35).

이상 설명한 바와 같이, 본 발명에 따르면, 흡입공기가 응축기를 통과하여 열교환이 되며 냉매는 소정의 사이클 내를 순환하므로 기존 건조기의 열교환기 내의 고온의 공기가 그대로 배출됨으로써 발생하는 에너지 낭비가 제거되고 응축기 후면의 패널에 의해 균일한 유속의 공기흐름이 가능하므로 건조효율이 증가하여 건조후 공기가 증발기를 통과하므로 배열의 회수가 가능하여 히트펌프의 효율증가가 가능하다.As described above, according to the present invention, since the intake air passes through the condenser to exchange heat, and the refrigerant circulates in a predetermined cycle, energy waste caused by the discharge of the high-temperature air in the heat exchanger of the existing dryer is removed, and the condenser The rear panel allows the flow of air at a uniform flow rate, so the drying efficiency is increased, and after drying, the air passes through the evaporator, allowing the recovery of the array, thereby increasing the efficiency of the heat pump.

또한, 보조 응축기를 통과하는 냉매량의 조절에 의해 건조온도의 조절이 가능한 건조기가 제공된다.In addition, there is provided a dryer capable of controlling the drying temperature by controlling the amount of refrigerant passing through the auxiliary condenser.
