Description
化学工学便覧、昭和43年5月10日全訂改版第3版発行、編者.社団法人化学工学協会
当発明の方法では対流気体の露点温度が乾燥温度を示す。当特許の方法での露点は、熱交換器の冷却熱媒の温度であり、外気を使用したクーリングタワーで冷却する場合は冷却水の温度、冷凍機で作る温度ではその温度が露点温度となる。
2.真空下の空気を圧力、温度、水分を考慮し、
3.真空下の乾燥物の品質は水分のある位置の温度が大きく影響することを考慮し、
4.真空装置を構成する乾燥室、真空ポンプ、熱供給、熱排出、空気流れなど幾多の設備コスト、運転コストを考慮し、
5.上記の1〜4の事項を総合的に考えて、最良の乾燥装置を考案した結果、図1に示す乾燥装置1の室内圧力を0.5atm以下、望ましくは0.3atm以下に維持し、大気圧下で回転したときに必要とする動力の1/2,望ましくは1/5〜1/10の動力で構成する送風機4を設置し、乾燥装置1の室内気体にエネルギーを与える熱交換器5と、熱交換器5に熱源を供給する熱源発生器6と、乾燥装置1の室内気体を循環する案内板11および12と、乾燥装置1の室内気体の水分を液体または氷にする熱交換器7と、熱交換器7で得たエネルギーを冷却する冷却装置8と、乾燥装置1の室内圧力を真空に維持する導管9と、真空ポンプ10とで構成する乾燥装置を基本構成とした。本特許の基本理念は多くの乾燥方式に適用できる。その一例として棚式置き式、流動式、噴霧式を示した。
トレー14は試料が積載保持できる金網や多孔板でよく、試料にトレーから乾燥エネルギーを与えるためのボイラーからの蒸気を導管で導く熱板にするとか、ヒーターで加熱するなどの必要はない。
図1,2,3の乾燥装置の気体流れ方向は上記説明の逆の方向で行っても同様の効果が期待できる。

Claims (1)
- 乾燥試料13を積載するトレー14と、乾燥装置1の室内気体にエネルギーを与える熱交換器5と、熱交換器5に熱源を供給する熱源発生器6と、乾燥装置1の室内気体の水分を液体または氷にする熱交換器7と、熱交換器7で得たエネルギーを冷却する冷却装置8と、乾燥装置1の室内圧力を真空に維持する導管9と、真空ポンプ10とで構成された乾燥装置において、乾燥装置1の室内圧力を0.1atm〜0.5atmに、望ましくは0.2atm〜0.3atmに維持し、該乾燥装置1内には、大気圧下で送風翼を回転したときに必要とする動力の1/2〜1/20の動力で構成する送風機4を設置することにより、常圧時の風量と同等である送風翼を有する送風機4を設置するとともに、乾燥装置1の室内気体を循環するための案内板11および12が並行に配置された2つの板で構成されたことを特徴とする乾燥装置。
