Abstract

A mixture of lignocellulose material in particulate form with spent cellulose liquor is formed into a blank and introduced into a hot press. The blank is subjected to heat and pressure and steam is withdrawn in an initial pressing stage. Then the press gap is enclosed and the spent cellulose liquor gasifies in the enclosed space, causing an increase in temperature and pressure, aiding in the rapid formation of a board. After the pressure has reached a desired level the pressure is controlled by venting any excess gas. The pressing is done in one press and treatment time is greatly reduced in comparison with prior processes.
