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 composition having a first moisture content to produce a substantially dry final product having a final moisture content;
• compressing and shearing the raw material composition between at least a first screw and a second screw comprising at least a compression zone and a dehydrating zone which are arranged successively within the at least first and second screw provided within a housing of an extruder as the raw material composition advances along and between the at least first screw and the second screw by:
• flowing the raw material composition at a first rate of speed through a first section of the first screw and the second screw;
• flowing the raw material composition, 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 composition, 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;
• entrapping a first predetermined percentage of the moisture within the raw material composition to facilitate flow as the raw material composition moves through the compression zone, after the compression zone releasing the first predetermined percentage of moisture from the raw material composition, and removing a second predetermined percentage of moisture from the first percentage of moisture via at least one vent as the raw material composition moves through the dehydrating zone to produce the substantially dry final product;
• and
• removing the moisture from the raw material to produce the substantially dry final product to have:
• i. a microbial spoilage resistant body having a highest protein and highest fat content as naturally possible that is free of additives such that the substantially dry final product has a density that inhibits spoilage and microbial growth when the substantially dry product is deposited onto a ground surface and exposed to various weather conditions;
• ii. the final moisture content is within a range of approximately 1%-15% by weight produced without heat treatment after ejection from the extruder;
• and
• iii. the final product remains stable and cohesive upon ejection from the extruder even though the final product contains some moisture.

• 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;
