본 연구는 표면 세척 시스템을 이용하여 유자의 미생물과 잔류농약 제거 효과를 살펴보았다. 선행 연구로 오징어 먹물을 제거 효과를 보기 위해 스프레이 회전 속도 0.11, 0.42, 0.73 m/s, 수압 0.6, 0.9, 1.2 MPa과 컨베이어 속도 0.046, 0.092, 0.138 m/s 으로 세척 조건을 달리하였다. 오징어 먹물 제거 실험 결과 먹물 제거 효율은 컨베이어 속도와 분사 노즐 회전수와는 높은 상관관계를 나타내었으며 수압의 조건

We developed a surface washing system for ginseng. The washing system was developed using different treatments and conditions and characterized in terms of product hardness, weight loss, and change in temperature and color. Optimal results were obtained using a surface washing system involving a washing conveyor speed of 1.0 L/min, a water pressure of , a washing nozzle angle of , a washing height of 5 cm, a 1-sec reciprocating washing nozzle cycle, a dehydration wind velocity of 30 m/sec, and an internal drying temperature of . A surface washing system using a washing conveyor speed of0.8 L/min, a water pressure of , a washing nozzle angle of , a washing height of 3 cm, a 1-sec reciprocating washing nozzle cycle, a dehydration wind velocity of 30 m/sec, and an internal drying temperature of resulted in ginseng that was stained yellow.
