  • Optimizing pellet mill controller
    Patent number: 5582847
    Abstract: A controller for controlling a pellet mill, used to extrude milled ingredients through a die into more manageable and economical pellets, keys particular control parameters to a library of pellet types and then adjusts the control parameters to optimize throughput within the limits imposed by potential plugging of the die. If a potential plugging is detected, the controller responds in two stages, intended to reduce the restart time for pluggings of less severity, and thus to allow more aggressive operation. Pellet fines are recycled and liquid ingredients compensated to provide improved efficiency.
    Type: Grant
    Filed: April 19, 1995
    Date of Patent: December 10, 1996
    Assignee: Repete Corporation
    Inventors: Norman R. Peterson, Richard A. Jorgensen, Mark E. Ossanna, Jeffrey J. Otten
