1.顆粒化液の調製
2.水およびPVPとのメサラジンの顆粒化
3.押出し

5.ミリング
6.篩い分け
7.コーティング
8.篩い分け
9.エアパージング
1バッチの顆粒化液用に、水をMullerドラムに充填する。ミキサーを適切な位置に入れ、開始させる。ポリビニルピロリドン(PVP)を、水上にゆっくりとふりかけ、全てのPVPが溶解するまで、一定時間前記ミキサーを運転させる。
メサラジンを、振動Prodimaホッパに入れ、コンベヤを用いて、ウェイトベルトフィーダまで運搬し、メサラジンを連続Niroラインに供給する。Niroラインの第1パートにおいて、メサラジンとPVPの水溶液とを混合して、ウェットマスにしてから押出し機内へ運搬する。スクリーンメッシュ0.9mmを通してメサラジンとPVP/水とのウェットマスの押出し後、この顆粒は、流動床ドライヤに直接落下する。
前記流動床ドライヤは、2つの主要な区画に分けられる。第1の区画において、顆粒を表面上で乾燥して、互いに固着するのを防ぐ。流動床のこの区画において、顆粒の無作為混合が行われる。ある一定の残留時間後、顆粒を、実際の乾燥が行われる前記ドライヤの第2のパートに移動させる。前記ドライヤの第2のパートにおいて、顆粒は、乾燥空気を用いて前記ドライヤ(鰓プレートにおける特殊パターンのホール)の中を導かれる。前記顆粒が乾燥されたら、流動床下にあるドラム内に落下させる。前記流動床は、流動床内の全居留時間が凡そ2.5時間になるような様式で構成される。
乾燥顆粒を含むドラムを、ミルの上部で転倒させて、長すぎる顆粒だけを砕くスクリーンを用いて静かに顆粒を粉砕する。ミルを通過後、顆粒をドラムに落下させる。
前記ミリング工程で、実際にはサイズ以下の顆粒が少量生じるため、顆粒を、Mogensen振動篩いを用いて篩い分けする。スクリーン0.8mmを通る顆粒を廃棄するか、または再処理用に採取して、気密の標識容器に保存できる。
200kgの篩い分け顆粒を、Kugel塗布機(流床システム)内で、アセトンに溶解させたエチルセルロースからなるコーティング液によりコーティングする。
コーティング工程後、コーティング顆粒を、Prodima回転篩いにおいて篩い分けする。大きな塊は廃棄する。
コーティング顆粒のバッチを篩い分け後、それらを、圧縮空気または窒素によるパージングのために2つのドラムに分ける。顆粒を6〜14時間パージする。このパージング工程は、コーティング顆粒中の残渣溶媒(アセトン)量を減少させるために必要である。
