The modular Rayeman Compression Dry

The modular Rayeman Compression Dryer, built in long and narrow sections, drops the moisture content of distillers grains between 8 and 14 percent per section, depending upon configuration. “The system is less than 6 feet wide and 10 feet tall at the highest point,” Thomas says. “The length will vary. Each section could be from 13 to 29 feet long, depending on what we’re trying to do.” The diameter of the extruder determines the volume—a 160 mm (6 inch) screw has a capacity of 100 to 300 dry tons per day, while the largest, at 360 mm, has a daily capacity between 900 and 1,500 tons. The sections are aligned horizontally, with the number of sections dependent upon the target dryness. “In an average dryer, to go from 65 to 12 percent moisture would need six to eight sections,” Thomas says. The system offers the flexibility to produce modified distillers, instead of dry, by using fewer sections.
