Title: Centrifugal thin-layer evaporator with tapered drum - having inclined rotor blades imparting movement opposite to that from taper
Inventor: MASAKI YASUNORI
IPC: B01D1/22
Filed: 1976-12-23
Abstract: A centrifugal thin layer evaporator comprises a conically tapering drum closed at both ends to form a conical frustum. The liq. inlet is at one end of the drum and the liq. outlet and vapour outlet are at the other end. A shaft rotationally mounted coaxially in the drum carries inclined blades which impart a centrifugal motion to the liq. thus spreading it uniformly in a thin layer over the entire inner surface of the drum and also impart an axial movement to the liq. towards the narrow end of the drum, in other works in the opposite direction to the trend of flow of the thin layer resulting from the centrifugal force. Used esp. for the evaporation of highly viscous liqs. Whereas, with a conically tapering drum only, there is a tendency for discontinuities to arise in the thin layer, with the present arrangement a continuous film is maintained uniformly over the entire inner face of the drum.
