METHOD AND DEVICE FOR REMOVING PLANT ADMIXTURES FROM FIBROUS MATERIAL

Document Type and Number:

WIPO Patent Application WO/1990/003459

Kind Code:

A1

Abstract:

The method consists in making a layer (1) of a fibrous material optically transparent and subjecting it to intense optical radiation under the influence of which the plant admixtures are removed by their thermochemical decomposition. A device implementing the method comprises an optical radiation source (3) and a system for permanent scanning of the optical radiation, the beam-rotating elements (12 and 13) of which are mounted over the width of the fibrous material layer (1) and are provided with a system for their protection against dirt.
