In the drawings, reference numeral 1 denotes a door formed in the main body, and 2 denotes a switch for driving the cooling fan 21 and the differential pressure fan 200.

이하 본 고안에 의한 컨테이너형 차압 예냉장치의 작용을 도 2 내지 도 4를 참조하여 설명하면 다음과 같다.Hereinafter, the operation of the container-type differential pressure precooling apparatus according to the present invention will be described with reference to FIGS. 2 to 4.

먼저 냉각팬(21)과 차압팬(200)이 구동되면 냉각팬(21)에서는 찬 공기가 배출되고, 차압팬(200)은 차압실(100)로 본체(10)의 내부(11) 공기를 유입시키므로 냉각팬(21)의 찬 공기는 차압시트(300)로 인하여 생성된 통로를 따라 농산물 또는 청과물이 보관된 부분을 통과하여 차압실(100)로 유입된다.First, when the cooling fan 21 and the differential pressure fan 200 are driven, cold air is discharged from the cooling fan 21, and the differential pressure fan 200 supplies air inside the main body 10 to the differential pressure chamber 100. Since the cold air of the cooling fan 21 is introduced into the differential pressure chamber 100 through the portion where the agricultural products or fruits and vegetables are stored along the passage generated by the differential pressure sheet 300.

그러면 차압실(100)로 유입되는 공기는 소정 각도(θ) 상방향으로 상향 설치된 덕트(210)에 의해 차압실(100) 상단으로 이송됨과 동시에 유입된 공기중에 포함된 수분(농산물 또는 청과물에서 분리된 수분)은 차압실(100) 바닥으로 떨어져 배수구(400)를 통해 외부로 배수된다.Then, the air flowing into the differential pressure chamber 100 is transferred to the top of the differential pressure chamber 100 by a duct 210 installed upward at a predetermined angle θ, and at the same time, water contained in the introduced air is separated from the agricultural products or fruits and vegetables. Moisture) drops to the bottom of the pressure differential chamber 100 and is drained to the outside through the drain hole 400.

차압실(100) 상단으로 이송된 공기는 다시 냉각팬(21)으로 유입되는데 이로 인하여 냉각팬(21)에서는 찬 공기와 차압실(100) 내의 공기 즉, 압력이 높은 공기가 만나서 풍속이 높아진 찬 공기가 다시 본체(10)의 내부(11)로 유출된다. 한편 정압 그릴(500)을 통해 차압실(100) 내의 공기는 본체(10)의 내부(11)로 유출되기 때문에 본체(10)의 내부(11)와 차압실(100)과의 높은 압력차에 의해 본체(10)의 내부(11)에 저장된 농산물 및 청과물이 손상되는 것을 방지하게 된다.The air transferred to the upper part of the differential pressure chamber 100 flows back into the cooling fan 21. As a result, the cold fan 21 meets the cold air and the air in the differential pressure chamber 100, that is, the air having high pressure, and thus the wind speed is high. Air again flows out into the interior 11 of the body 10. On the other hand, since the air in the differential pressure chamber 100 is discharged to the interior 11 of the main body 10 through the positive pressure grill 500, a high pressure difference between the interior 11 of the main body 10 and the differential pressure chamber 100 is increased. This prevents the agricultural products and fruits and vegetables stored in the interior 11 of the main body 10 from being damaged.

이러한 반복적인 과정을 통해 본체에 찬 공기를 빠른 속도로 순화시킴으로써 본체에 저장된 농산물 및 청과물이 2~3시간 내에 예냉이 가능하게 된다.Through this repetitive process, the cold air in the main body is rapidly purified to allow pre-cooling of agricultural products and fruits and vegetables stored in the main body within 2 to 3 hours.

상기와 같이 구성된 본 고안에 의한 컨테이너형 차압 예냉장치에 의하면 예냉장치 내에 차압실과, 차압팬을 구비하여 예냉 시간을 2~3시간 내로 단축시켜 농산물 및 청과물의 신선도를 장기간 유지시키고, 농산물 및 청과물의 외피에 결로가 발생하는 것을 방지하여 저온저장시 곰팡이가 발생하는 것을 막을 수 있다.According to the container-type differential pressure precooling device according to the present invention configured as described above, the pre-cooling device is provided with a differential pressure chamber and a differential pressure fan to shorten the pre-cooling time within 2 to 3 hours to maintain the freshness of agricultural products and fruits and vegetables for a long time, It prevents the formation of condensation on the skin and prevents the formation of mold during low temperature storage.
