The present invention relates to a system for vacuum drying agricultural and marine products. The system of the present invention comprises a drying unit (10) equipped with an air supplying line (L1), an air discharging line (L2), and an air blowing out line (L3) a vacuum pump (20) for blowing the internal air of the drying unit (10) to the outside through the air blowing out line (L3) to be made into a vacuum state of 0.2-0.3 air pressure an evaporator (30) for cooling wet air discharged through the air discharging line (L2) and removing moisture in air a condenser (40) for heating air dehumidified through the evaporator (30) a blower (50) installed in the air supplying line (L1) first, second, third, and fourth refrigerant circulating lines (RL1, RL2, RL3, RL4) connected with the evaporator (30) and condenser (40) to circulate therethrough and having a refrigerant circulated therein a compressor (60) installed in the first refrigerant circulating line (RL1) for supplying a refrigerant to the condenser (40) to compress the refrigerant an expansion valve (70) installed in the second refrigerant circulating line (RL2) connected to supply the refrigerant passed through the condenser (40) to the evaporator (30) and a controller for respectively controlling the vacuum pump (20), blower (50), and condenser (60). In the present invention, the system can be selectively operated relevantly to high temperature conditions and low temperature conditions according to the dried product, and the heat energy consumption rate for drying can be reduced.COPYRIGHT KIPO 2015본 발명은 농수산물 진공 건조 시스템에 관한 것으로, 본 발명은 공기공급라인(L1)과 공기배출라인(L2) 및 공기취출라인(L3)이 각각 구비되는 건조유닛(10)과 상기 공기취출라인(L3)을 통해 상기 건조유닛(10)의 내부 공기를 외부로 취출하여 0.2 ~ 0.3기압의 진공상태로 만드는 진공펌프(20)와 상기 공기배출라인(L2)을 통해 배출되는 습공기를 냉각하여 공기 중의 수분을 제거하는 증발기(30)와 상기 증발기(30)를 통해 제습된 공기를 가열하는 응축기(40)와 상기 공기공급라인(L1)에 설치되는 블로워(50)와 상기 증발기(30)와 응축기(40)를 순환하도록 연결되어 내부에 냉매가 순환되는 제1, 2, 3, 4냉매순환라인(RL1, RL2, RL3, RL4)과 상기 응축기(40)로 냉매를 공급하는 상기 제1냉매순환라인(RL1)에 설치
