PURPOSE: A red pepper drying method and an apparatus thereof are provided to uniformly blow hot air to the upper and lower sides of red pepper which is transferred by an air-permeable conveyor.CONSTITUTION: Red pepper is transferred to an air-permeable conveyor(30) moving toward one direction. 90-110°C steam is supplied to the lower side of the red pepper for steaming the red pepper. 90-110°C hot air is supplied to the red pepper for drying. 70-90°C hot air is supplied to the firstly dried red pepper from the lower side of the conveyor. 40-70°C hot air is supplied to the secondly dried red pepper from the lower side of the conveyor. Air at a room temperature is supplied to the red pepper from the lower side of the conveyor for cooling. The hot air is reheated during the final drying process, and circulates to the second heating process.COPYRIGHT KIPO 2013본 발명은 통기성 컨베이어 하부에서 공기공급덕트의 타공망을 통해 열풍을 공급하므로 통기성 컨베이어에 의해 이송하는 고추의 하부 및 상부에 골고루 전달되므로 건조효율을 향상시킬 뿐만 아니라 마무리 건조단계에서 고추를 건조시킨 열풍은 재건조단계로 순환되며 재건조단계의 열풍은 초벌 건조단계로 순환되어 배기부를 통해 배기되도록 함으로써 열손실을 방지하여 에너지 효율을 향상시키는 고추 건조방법 및 장치에 관한 것이다.
