Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

open access: yesChemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.
