図5は、本発明の第4の実施形態に係る有機材料の精製装置1Gの断面図である。図示されているように、本実施形態において、内筒体2Gは、対向する1対の平坦面23Gを有する。内筒体2Gは、1対の平坦面23G以外の部分では円筒状である。つまり、内筒体2Gの断面形状は、円筒状の部分に対応する2つの円弧と、1対の平坦面23Gによって形成される円弧の2つの弦とを含む。1対の平坦面23Gも、上記の第2の実施形態における内筒体2Eの平坦面23と同様に、内筒体2Gの周面に含まれる切取面の例である。
図6は、本発明の第5の実施形態に係る有機材料の精製装置1Hの断面図である。図示されているように、本実施形態において、精製装置1Hは、第1の実施形態と同様の内筒体2を有する。加えて、本実施形態では、内筒体2の捕集区間22の内部に板部材6が配置される。板部材6は、内筒体2の長さ方向に延び、断面形状において互いに交差する第1の板部材61および第2の板部材62を含む。それ以外の点について、本実施形態の構成は上記の第1の実施形態と同様であるため、重複した説明は省略する。
図7は、本発明の第6の実施形態に係る有機材料の精製装置1Jの断面図である。図示されているように、本実施形態において、精製装置1Jは、第2の実施形態と同様の内筒体2Eを有する。加えて、本実施形態では、内筒体2Eの捕集区間22の内部に、内筒体2Eの長さ方向に延びる板部材6Jが配置される。それ以外の点について、本実施形態の構成は上記の第2の実施形態と同様であるため、重複した説明は省略する。
図8Aから図8Hは、本発明の他の実施形態に係る有機材料の精製装置の内筒体2Kの断面図である。図8Aから図8Hには、それぞれ異なる内筒体2Kの断面形状が例示されている。他の実施形態において、内筒体2Kの断面形状は、長さ方向に延びる少なくとも1つの平坦面23Kを含むものであれば特に限定されない。
