Description

【発明の詳細な説明】 このバイオ反応器は、流入液、或いは、流入液およびリサイクルされる材料の混 合物のためのインレットシステムおよびこのシステムの上に位置させられた反応 室を有する反応容器(1)を備えている。閉塞のおそれや、過度の摩耗の問題が 引き起こされることなしに、(リサイクルされる材料と混合される)流入液の良 好な分布を作りだすために、流入液用のインレットシステム(12)の流出開口 部が、少なくとも部分的に、接線方向に向けられるとともに、流入液用のインレ ットシステムが、仕切り部によって、反応室から分離させられたチャンバー(2 )内に位置させられている。この仕切り部は、ある距離だけ離間して、鉛直方向 に互いに重なりあう二つの放射状のエツジストリップ(4a、 4b)から形成 される放射状のスリット(13)を、少なくとも一つ存している。この放射状の スリットが、前記流入液用のインレットチャンバーと反応室との間の接合部を形 成している。
