According to an embodiment of the present invention, a pepper dryer includes a dehumidifying unit and a pepper drying unit. The dehumidifying unit includes: a condenser which converts a compressed gas-phase refrigerant with a high temperature and a high pressure to a liquid-phase refrigerant with the high temperature and high pressure an expander which converts the liquid-phase refrigerant with the high temperature and high pressure passing through the condenser to a liquid-phase refrigerant with a low pressure and a low temperature an evaporator which converts the liquid-phase refrigerant with the low pressure and low temperature converted in the expander to a gas-phase refrigerant a compressor which converts the gas-phase refrigerant with the low pressure and low temperature converted in the evaporator to a gas-phase refrigerant with a high temperature and a high pressure a first blowing fan which is installed near the evaporator to let high-temperature and moist gas entering from the pepper drying unit pass through the evaporator a second blowing fan which is installed near the condenser to let the low-temperature and dry gas dehumidified in the evaporator while having the temperature lowered pass through the condenser an inlet pipe used as a path for letting the high-temperature and dry gas passing through the condenser enter the pepper drying unit an outlet pipe used as a path for letting the high-temperature and moist gas discharged from the pepper drying unit enter the dehumidifying unit an inlet coupler connecting the inlet pipe and the pepper drying unit and an outlet coupler connecting the outlet pipe and the pepper drying unit.COPYRIGHT KIPO 2017본 발명의 실시예에 따른 고추건조기는 제습부와 고추건조부를 포함하는 고추건조기로서, 상기 제습부는 고온고압의 압축된 기체상 냉매를 고온고압의 액체상 냉매로 상전환시키는 응축기, 상기 응축기를 통과한 고온고압의 액체상 냉매를 저온저압의 액체상 냉매로 변환하는 팽창기, 상기 팽창기에서 변환된 저온저압의 액체상 냉매를 기체상 냉매로 상전환시키는 증발기, 상기 증발기에서 변환된 저온저악의 기체상 냉매를 고온고압의 기체상 냉매로 변환하는 압축기, 상기 증발기의 인근에 설치되어 고추건조부에서 유입되는 고온다습한 가스를 증발기로 통과시키는 제1송풍팬 및 상기 응축기의 인
