Patent ID: 7964059

Claim:
A large volume reactor comprising: a housing enclosing a reactor chamber; a reactor rotor disposed in the reactor chamber; a reactor chamber inlet opening leading into the reactor chamber; a product outlet leading away from the reactor chamber; and a premixing unit comprising a stator and a rotor mounted on a drive shaft and cooperating with the stator for mixing a starting material supplied via a product inlet opening and having a unit outlet opening which is located adjacent and in communication with the reactor chamber inlet opening; wherein the premixing unit is a radial premixing unit conveying the starting material radially outward with respect to the axis of rotation of the rotor during the mixing of the starting material; wherein the rotor is cup-shaped and includes a rotor base which faces the reactor chamber and is mounted on the drive shaft, and an annular rotor casing which is fixedly connected to the rotor base and is arranged concentrically to the shaft; wherein the stator comprises an annular stator part arranged concentrically to the annular rotor casing, and wherein the annular rotor casing and the annular stator part each comprise radial openings; and wherein the annular stator part lies radially inward in relation to the annular rotor casing and is mounted on a stator flange which extends radially outward from the annular stator part and which covers the rotor.
