Description
2500kgの結晶化エチレン尿素を加熱可能な攪拌容器に供給し、80℃に加熱し、次いでそれ自体の結晶水に融解させた。この生成融解物を、水で25〜33℃に冷却したフレーキングローラー上に100〜300kg/hの量で直接的に搬送した。これにより、約0.5〜1mmの厚さの白色で不規則な形状のエチレン尿素のフレークを2440kg得た。長さと幅はそれぞれ約1〜2cmであった。フレークは乾燥した感触を有していたが、水を分離し得る更なる工程が融解工程とフレーキング工程の間になかったので結晶化材料と同じ水含有量を有していた。
エチレンジアミンと尿素との反応により得られた粗エチレン尿素の高温の融解物4000kgを、攪拌容器内で400kgの水と可能な限り早く混合し、80℃に冷却した。このようにして得られた生成融解物を、まず遠心ディスクフィルター(centrifugal disk filter)を通して80℃において何度も濾過し、次に100〜300kg/hの流速で、水で25〜33℃に冷却したフレーキングローラー上に搬送した。これにより、白〜淡黄色で、約0.5〜1mm厚で、不規則な形のエチレン尿素フレークを4200kg得た。長さと幅は、それぞれ約1〜2cmであった。水の含有量が9質量%であるにもかかわらず、フレークは乾燥した感触を有していた。
