Deodorising cork by removal of tri:chloro:anisole - using increased mobility of steam molecules to penetrate cork structure, allowing steam distillation to take place
Method, and appts. for deodorisation of cork, particularly the removal of 2,46-trichloroanisole which has a characteristic odour, the method comprises (a) putting the cork in a container, (b) supplying steam to the container for generating steam flow at a given temp. and a given pressure, being selected for penetrating steam molecule into internal structure of cork and promoting steam distillation within the internal structure of cork, (c) discharging the steam past the cork and contg. the substance originating offensive odour, from the container, in which (d) the substance originating offensive odour may be 2,4, 6-trichlorophenol, which may be precursor of 2,4, 6-trichloroanisole. -
