Abstract

Dry washing by air and sand to clean dishes was investigated for establishing a dry washing process in a kitchen. Thirty seasonings and foods as dirt markers and fourteen kinds of dishes were used for the experiment, and washing efficiency was evaluated by COD-MN (mg/L). It was found that air dry washing effectively reduced COD-MN of some dirt markers but not effective at all to some dirt markers. It could be also said that dirt markers would not be completely removed by air dry washing. The shape of dishes also affected COD-MN reduction by air dry washing. Sand dry washing showed excellent efficiency on COD-MN reduction. Combination of air and sand dry washing may be necessary to make a dish dry washing system which is completely independent from water.

공기와 모래를 이용한 건식 식기세척기를 주방에 설치하여 운전하였다. 실험을 위하여 30여종의 양념(Dirt 마커) 과 14종의 접시를 사용하였으며 세척효율은 COD-MN에 의해 평가하였다. 건식 공기세척은 일부 양념에는 효과적이었으나 일부 양념에는 전혀 효과가 없는 것으로 분석되었다. 또한 건식공기세척을 통해서 양념의 완벽한 제거는 불가능하였다. 접시의 형태에 따라 세척효율에 큰 차이를 보였다. 모래와 공기에 의한 세척은 COD-MN 제거에 탁월한 성능을 보였다. 본 연구를 통하여 물을 사용하지 않고 모래와 공기에 의한 건식세척 방법이 가능함이 입증되었다.
