Grain dehydrating compressor for wet grain system and method

A substantially dry product produced by the process comprising:

• removing in sequential stages moisture from a raw material having a first moisture content to produce a substantially dry final product having a final moisture content;
• compressing and shearing the raw material between at least a first screw and a second screw provided within a housing as the at least the raw material advances along and between the at least first screw and the second screw by:
• flowing the raw material at a first rate of speed through a first section of the first screw and the second screw;
• flowing the raw material, after the first section, at a second rate of speed through a second section of the first screw and the second screw, wherein the second rate of speed is slower than the first rate of speed;
• and
• flowing the raw material, after the second section, at a third rate of speed through a third section of the first screw and the second screw, wherein the third rate of speed is slower than the first rate of speed and faster than the second rate of speed;
• and
• removing, via at least one vent positioned along the housing, approximately up to 95% of moisture from the raw material;
• entrapping approximately 5% of the moisture within the raw material to improve lubricity of the raw material as the raw material flows between the at least first screw and the second screw;
• and
• altering a physical property of the raw material as the raw material advances along and between the at least first screw and the second screw by compressing and shearing the raw material to squeeze moisture from the raw material and vaporize the moisture by substantially increasing an initial temperature of the raw material to approximately 220° F., without supplying additional heating, to produce the substantially dry final product.

• compressing and shearing the raw material between at least a first screw and a second screw provided within a housing as the raw material advances along and between the at least first screw and the second screw by flowing the raw material through:
• a backup region, a first aggressive section, and a second aggressive section included within at least one of the first screw and the second screw, the backup region is provided between the first aggressive section and the second aggressive section, wherein the first aggressive section includes at least one of a fewer number of first flights than the second aggressive section and the first flights having a pitch relatively less perpendicular to a direction of movement of the raw material moving along the screws than the second aggressive section, and wherein the second aggressive section includes at least one of a greater number of second flights than the first aggressive section and the second flights having the pitch relatively more perpendicular to the direction of the movement of raw material moving along the screws than the first aggressive section, the backup region is configured to slow down and back up the raw material creating a lateral compression as the raw material advances along the screws, and the backup region is configured to generate heat as the raw material transitions from the first aggressive section to the second aggressive section;
