摘要：
This paper describes the experimental study of a new process for freeze-drying based on a fluidized bed of dry adsorbent working at atmospheric pressure. Process feasibility has been demonstrated. The kinetics of dehydration have been established systematically for thin-sliced potatoes. A comparison has been carried out with vacuum freeze-drying. Processing time is longer than under vacuum freeze-drying, but energy savings of 35% can be expected from a continuous duty facility. © 1990, Taylor & Francis Group, LLC. All rights reserved.
