Abstract
A pilot plant scale freeze dryer was designed and manufactured and its performance was tested. Freezing capacity of water vapor in the developed freeze dryer was 8㎏/batch and heating and defrosting methods were conduction and hot gas types, respectively. And exhausting time of vacuum pump was 7-8 minutes and temperature of cold trap was kept below
식품 산업에서 이용도가 높을 뿐 아니라 외국 의존도가 높은 진공동결건조기를 reverse enginerring 하여 국산화 개발한 후 그 성능을 시험하였다. 새로 개발한 진공동결건조기는 1 batch 당 8kg의 수증기를 응결시킬 수 있으며, 전도가열에 의해 열판 온도를
