PULP MAKING TECHNOLOGY USING EMPTY FRUIT BUNCHES (EFB) OF OIL PALM BY A METHOD OF HIGH-DENSITY EXTRUDING RECYCLING SYSTEM

摘要

A PULP-MAKING TECHNOLOGY USED A METHOD OF HIGB-DENSITY EXTRUDING RECYCLING SYSTEM OF OIL PALM EFB CHARACTERIZED IN THAT A PROCESS FLOW OF PULP-MAKING COMPRISES OF WASHING (220) PALM FIBERS (202), STEAM COOKING (240), HOT WATER OR THERMOKALITE PRE-TREATMENT (260), 1# TWIN SCREW EXTRUDER (300A), 1# REACTION TANK , 2# TWIN SCREW EXTRUDING REFINER (300B), 2# REACTION PIPE (320B), ONE-STAGE HIGH-DENSITY REFINING (340), TWO-STAGE MEDIUM-DENSITY REFINING (360), LATENCY TANK (380), FILTERING AND PURIFYING (400), THICKENER (420). AND PULP FORMING CHEST (440), WHEREIN PULP-MAKING BLEACHING CHEMICALS (460A, 460B) ARE INJECTED RESPECTIVELY INTO 1# TWIN SCREW EXTRUDER (300A) AND 2# REFINER (300A).
