Research Paper: 噴霧乾燥：単一液滴の高分子分析による顆粒精密制御 (2025) Spray Drying: Precision Granule Production via Water-Soluble Polymers

産業界の基幹技術である噴霧乾燥法において、複合スラリーの乾燥は依然「試行錯誤」が課題です。本論文は、水溶性高分子（PVA）が液滴内で「隠れた設計者」として働き、最終的な顆粒構造を決定づけていることを解明。この知見は、粒子の欠陥を予測し、製造プロセスに精密な制御をもたらします。Spray drying complex slurries is often guesswork, hindering high-value granule production. This paper reveals the water-soluble polymer (PVA) acts as a “hidden architect” inside a single droplet, fundamentally controlling the final particle structure. This breakthrough moves material manufacturing from trial-and-error to precision control, allowing prediction of particle defects.
