1. An extruder for processing hydrocarbon-containing material comprising:
a motor;
a gear box that is connected or interconnected to said motor;
an auger barrel;
a screw rotatably positioned in said auger barrel, said screw connected or interconnected to said gear box such that said gear box causes said screw to rotate when said motor is activated, said screw includes a flight positioned on an outer surface of a core of said screw, said flight extending along at least a portion of a longitudinal length of said screw, said flight having a flight spacing, said screw having a variable root depth along said longitudinal length of said screw wherein said root depth is defined by a distance between said outer surface of said core of said screw and a top surface of said flight on said screw, said screw including a first and second portions, a first end of said first portion connected or interconnected to said gear box, a second end of said first portion connected to a first end of said second portion, a flight spacing of said first portion decreasing from said first end to said second end of said first portion, said root depth of said first portion decreasing from said first end to said second end of said first portion, said first and second portions of said screw separated by a first flight break; and,
a heating system positioned about at least a portion of said auger barrel, said heating system heating said hydrocarbon-containing material as said hydrocarbon-containing material moves through said auger barrel as said screw rotates.
