The present invention relates to a drying equipment, which can perform drying and dehumidifying an object to be dried, such as agricultural and marine products. The dying equipment comprises a drying chamber, a mechanical chamber, a first compressor, a first condenser, a first expansion valve, an evaporator, a second compressor, and a second condenser. The drying chamber accommodates the object to be dried. The mechanical chamber supplies air to the drying chamber via an air supply port, and injects air from the drying chamber through an air inflow port. The first compressor receives a coolant from a first liquid separator and compresses the coolant at high temperatures and high pressure. The first condenser is placed in an air supply port and heat-exchanges air discharged from a mechanical chamber with the coolant supplied from the first compressor, and supplies the coolant which has been heated to the drying chamber. The expansion valve receives and decompresses coolant condensed through a first condenser. The evaporator heat-exchanges a low-temperature and low-pressure coolant supplied from the first expansion valve with air introduced from the drying chamber to evaporate moisture contained in the air. The second compressor receives a coolant from a second liquid separator and compresses the coolant at high temperatures and high pressure. The second compressor is arranged between the first compressor and the evaporator and heat-exchanges air cooled by the evaporator with coolant supplied from the second compressor and supplies the coolant which has been heated to the first condenser.COPYRIGHT KIPO 2015농수산물 등과 같은 건조 대상물의 건조 및 제습을 동시에 수행할 수 있도록 형성된 건조장치에 관한 것이다. 건조장치는 건조실과, 기계실과, 제1 압축기와, 제1 응축기와, 제1 팽창밸브와, 증발기와, 제2 압축기, 및 제2 응축기를 포함한다. 건조실은 건조 대상물을 수용한다. 기계실은 공기 공급구를 통해 건조실로 공기를 공급하며, 건조실로부터 공기 유입구를 통해 공기를 유입시킨다. 제1 압축기는 제1 액분리기로부터 냉매를 공급받아 고온고압의 상태로 압축한다. 제1 응축기는 공기 공급구에 배치되며, 기계실로부터 배출되는 공기를 제1 압축기로부터 공급받은 냉매와 제1 열교환시켜 가열한 후 건조실로 공급한다. 제1 팽창밸브는 제1 응축기를 거쳐 응축된 냉매
