Abstract

"Method to obtain paper pallet of cellulosic agricultural material", characterized by exposing the material in a first zone to saturated steam while stirring the material to heat it to substantially the temperature of said steam, transporting it to a second zone where it is chemically defibrated to the temperature of said steam and then transporting it to a third zone for additional pulping action and stirring the material in the presence of saturated steam.
