through line 34 and is conducted to screw press 36 water and chemicals rejected in screw press 36 are recycled through line 38 the fibers from screw press 36 are conducted through line 42 to a shredding conveyer 44 and thence through line 46 to rotary feed valve 48 and a defibrator 49 into pressurized dryer 50 pressurized dryer 50 is of the type disclosed in u s pat no 4 244 778 and 4 043 049 the entire disclosure of both being herein incorporated by reference as can be seen pressurized dryer 50 comprises a long tortuous partially steam jacketed tube 51 having numerous bends 54 formed therein as disclosed in said u s pat no 4 244 778 a turbulent flow is created which entrains the fibers and leads to additional fiber individualization and or fluffing the dried fiber exits through line 55 into cyclone 60 wherein steam can be recycled through line 61 fiber which is separated in cyclone 60 passes through line 62 to the curing section 65 via rotary valve 63 and fluffer 64 optional curing section 65 is substantially identical to dryer 50 and is of substantially the same construction as the equipment disclosed in u s pat no 4 244 778 except that the materials used must be capable of withstanding the higher temperatures involved in the practice of the present invention flow through the curing tube provides turbulence which entrains the fiber in superheated steam the fiber.
