Abstract

A process for manufacturing reconstituted wood products comprising (A) producing a hydrophobing emulsion in a homogeniser in a mother plant and also in one or more mini plant homogenisers remote from the mother plant, the miniplant homogenisers being operably connected, optionally with intermediate storage, for supplying hydrophobing emulsion to one or more impregnators and (B) impregnating fibrous and/or particulate material with hydrophobing emulsion from the mother plant and from the one or more miniplant homogenisers. The invention also relates to an apparatus for performing the process. The impregnators are thus provided with alternative sources of emulsion.
