Description
본발명은 농산물 저온저장고에 관한 것으로, 특히, 농산물을 저장시 저장물의 상처치유와 곰팡이균의 멸균을 위한 큐어링(curing)작업을 하거나, 저장을 위한 건조작업을 초기 저장상태에서 실시할 수 있는 다기능성 저장고를 제공하는데 그 목적이 있고, 다른 목적은 겨울철 온도조절시 실외 공기를 이용하여 저장실내의 적정온도 유지하게 함으로서 겨울철에 쿨러사용을 억제함으로서 전력소모를 줄여 저장고를 경제적으로 운영할 수 있게 하는 것과, 저장실내에 필요한 습기를 공급하여 농산물을 장기간 신선하게 저장할 수 있게 하는데 그 목적이 있다.The present invention relates to a low temperature storage of agricultural products, in particular, when storing the agricultural products can be cured (curing) for the wound healing and sterilization of the fungus, or drying operation for storage can be carried out in the initial storage state Its purpose is to provide a multi-functional storage room, and another objective is to maintain the proper temperature in the storage room by using outdoor air during winter temperature control, thereby restraining the use of the cooler in winter to reduce power consumption and to operate the storage economically. The purpose is to supply the necessary moisture in the storage compartment so that fresh produce can be stored for a long time.
일반적으로 고구마, 감자, 양파 마늘등과 같은 농산물을 저장할 때에는 저장실에 설치된 온도센서에 의해 구동되는 쿨러로 저장실내의 공기를 상부에서 저면의 순환통로에 흡인된 후 벽에 설치된 닥트를 거쳐 쿨러에 의해 저장실 상부로 토출됨을 반복하는 탑다운(top down)방식으로 순환시켜 저장실내의 적정온도를 유지하도록 구성되어 있었다.Generally, when storing agricultural products such as sweet potatoes, potatoes, onions, garlic, etc., it is a cooler driven by a temperature sensor installed in a storage compartment. It was configured to maintain a proper temperature in the storage chamber by circulating in a top down method of repeatedly discharging to the upper chamber.
이상과 같은 종래의 농산물저장에 있어서, 고구마 감자등과 같은 농산물은 저장 전에 별도의 시설에서 큐어링작업을 하거나, 마늘등과 같은 농산물은 저장을 위한 건조작업을 한 다음 이를 저장고에 저장하게 되는데, 종래의 저온 저장고는 가습장치가 없이 저장실내의 공기 만을 쿨러로 탑다운방식으로 순환시켜 온도조절을 하는 구성이므로 저장고 자체로는 큐어링작업 또는 초벌건조작업을 할 수 없었고, 큐어링작업 후 일정기간 배출되는 탄산가스의 배출이저장고 내는 공기가 건조해지면서 습도가 부족하여 농산물이 필요이상으로 건조되어 신선도가 떨어지는 문제점이 있었고, 신선도가 떨어지면 건조되면 농산물이 변질되기 때문에 저장기간이 단축되는 문제점이 발생하였으며, 겨울철에도 전력소모가 큰 쿨러를 구동하여 온도를 조절하게 됨으로 비경제적인 문제점이 있었다.In the conventional agricultural product storage as described above, agricultural products such as potatoes, potatoes, etc. are cured in a separate facility before storage, or agricultural products such as garlic, etc. are dried for storage, and then stored in the storage. Conventional low-temperature storage room is configured to circulate only the air in the storage room with a cooler in a top-down manner without a humidifier, so that the storage itself can not be cured or roughly dried, and after a certain period of time There is a problem in that the freshness of the discharged carbon dioxide is stored in the reservoir as the air is dried and the humidity is insufficient, so that the produce is dried more than necessary and the freshness is decreased. In winter, it uses cooler which consumes a lot of power to control the temperature. There was an uneconomical problem.

In the present invention, in order to solve the problems of the conventional cold storage as described above, and to store fresh produce such as sweet potatoes, potatoes, onions, garlic, pepper, etc. for a long time, the outside is opened by a temperature sensor in the storage chamber duct of the cold storage. Heater operated by air inlet and temperature sensor and blower which are sucked and blown are installed to heat storage room air with heater according to the object to be stored so that curing work can be done in storage room or drying work for storage. In case of curing, the storage room air is returned to the blower, and the respiratory heat and carbon dioxide generated from the curing work are discharged to the air discharger to adjust to the first set temperature. Blowing the outside air sucked into the outside air inlet by the blower, After being humidified while passing through the circulation passage at the bottom of the storage compartment, it is discharged into the storage compartment through a vent cover (grouting) covering the circulation passage at the bottom of the storage compartment.

이상과 같은 본 발명 저장고는 농산물의 종류에 따라 저장시 저장실(101)에 넣은 후 히터(20)와 송풍기(30)를 작동시켜 큐어링작업 또는 건조작업을 한다.The storage of the present invention as described above is put into the storage compartment 101 during storage according to the type of agricultural products and then the heater 20 and the blower 30 to operate the curing or drying operation.
예를들면, 감자,고구마등은 저장실(101) 내부온도를 약 35℃ 내지 40℃로 상승시킨 상태에서 약 3일 내지 4일 동안 내부공기를 회류시켜 저장 농산물의 상처치유와 곰팡이균을 멸균하는 큐어링작업을 하며, 마늘,고추등은 저장실(101) 내부온도를 약 45℃ 내지 55℃로 상승시킨 상태에서 약 10시간 내지 15시간 동안 내부공기를 회류시켜 건조작업을 한다.For example, potatoes, sweet potatoes, etc. to sterilize the wound healing and fungal bacteria of the stored agricultural products by returning the internal air for about 3 to 4 days while raising the internal temperature of the storage compartment 101 to about 35 ℃ to 40 ℃ Curing work, garlic, pepper, etc. while drying the internal air for about 10 hours to 15 hours while raising the internal temperature of the storage room 101 to about 45 ℃ to 55 ℃.
상기와 같은 큐어링작업 또는 건조작업이 끝난 후에는 저장실(101) 내부공기를 송풍기로 회류시키면서 큐어링작업시 발생한 농산물의 호흡열과 탄산가스를 공기배출기로 배출하면서 1차 저장실의 설정온도 까지 조절한다. After the curing or drying operation as described above, the internal air of the storage compartment 101 is returned to the blower, and the breathing heat and carbon dioxide gas of the agricultural products generated during the curing operation are discharged to the air discharger to adjust the set temperature of the primary storage compartment. .
일단 설정온도조절이 끝난 농산물을 장기 저장시에는 내부온도가 올라갈때 마다 이를 내부온도 감지센서(140)가 감지하여 외부공기유입구(10)와 공기배출기 (60)를 열어주면서 공기배출기(60)로는 열을 배출시키고, 외부공기 유입구(10)로 흡입된 외부공기는 닥트(120)로 유입된 내부공기와 함께 순환통로(130)로 송풍하고, 송풍된 공기는 순환통로(130) 하위의 저수실(40)을 거치는 동안 가습시켜 저장실(101) 저면의 순환통로(130)를 덮고 있는 통기덥개(131)을 통해 저장실(101)로 토출시킨다. 토출되어 상승된 공기는 송풍기(30)의 흡인력으로 닥트(120)의 상부 통기구로 흡인된 후 재차 순환통로(130)를 거쳐 저장실(101)로 토출되는 버텀업 (bottom up)방식으로 회류되어 저장실 저장설정온도를 유지 한다.Once long-term storage of the agricultural products after the set temperature control is set, the internal temperature sensor (140) is detected every time the internal temperature rises to open the external air inlet (10) and the air discharger (60) while heat to the air discharger (60) Exhaust air, and the outside air sucked into the outside air inlet 10 is blown into the circulation passage 130 together with the internal air introduced into the duct 120, and the blown air is stored in the storage chamber below the circulation passage 130 ( 40 is humidified while passing through the vent cover 131 covering the circulation passage 130 on the bottom surface of the storage compartment 101 to the storage compartment 101. The discharged and raised air is sucked into the upper vent of the duct 120 by the suction force of the blower 30, and is then returned to the storage chamber 101 through the circulation passage 130 to be returned to the storage chamber 101, thereby being stored. Maintain storage set temperature.
상기 동작중 내부 온도감지센서(140)가 실내온도상승을 감지하면, 공기배출기(60)와 공기유입구(10)가 열려 공기배출기(60)로는 열을 배출하는 한편 공기유입구(10)를 통해 외부공기를 유입시켜 온도조절을 하게되고, 이때 공기유입구(10)로 유입되는 공기가 저장실(101) 설정온도와 차이가 큰 겨울철에는 이를 외부 온도감지센서(50)가 감지하여 쿨러(110)는 정지시키고, 히터(20)를 가동시켜 가열공급되게 하므로서 저장물의 냉해피해가 없이 온도조절을 한다.When the internal temperature sensor 140 detects the increase in the indoor temperature during the operation, the air discharger 60 and the air inlet 10 are opened to discharge heat to the air discharger 60 while externally passing through the air inlet 10. The temperature is controlled by introducing air, and in this case, when the air flowing into the air inlet 10 has a large difference from the set temperature of the storage compartment 101, the external temperature sensor 50 detects this and the cooler 110 is stopped. And, by operating the heater 20 to be supplied with heat to control the temperature without cold damage of the stored matter.
이상과 같이 본 발명은 농산물을 초기 저장시에 저장실에서 히타를 이용하여 큐어링작업 또는 건조작업을 할 수 있는 다기능 효과가 있고, 가을철에서 이듬해 봄까지의 온도가 낮은 시기에는 저장실내의 적정온도 유지시 쿨러를 사용하지 않고 실외 공기를 이용함으로서 쿨러작동으로 인한 전력소모를 줄여 경제적으로 저장고를 운영할 수 있는 효과가 있고, 저장실내에는 신선한 외부공기를 유입하고 이를 가습하여 회류시킴으로서 종래에 실내공기 만을 순환시키는 저장방법에 비하여 농산물을 신선하게 장기간 저장할 수 있는 효과가 있다.As described above, the present invention has a multi-functional effect that can be cured or dried by using a heater in the storage room at the time of initial storage of agricultural products, and at the time when the temperature is low from the autumn to the next spring, when maintaining the proper temperature in the storage room. By using outdoor air without using a cooler, it is possible to operate the storage economically by reducing power consumption due to the operation of the cooler, and circulate only indoor air conventionally by introducing fresh external air into the storage room and humidifying it. Compared to the storage method to ensure that fresh produce can be stored for a long time.
