  • Airline cleaner for seed cotton
    Patent number: 4905351
    Abstract: An airline cleaner has a cylindrical cage coaxial and the same diameter as a pipe connected to either end of the cage. Helical vanes around the circumference of the cage cause the air and seed cotton moving through the pipe in the cage to move in a helical motion as they move through the cage. The helical motion will wipe the seed cotton against the cage, and trash will fall through spaces in the cage, thus being removed from the seed cotton. A housing surrounds the cage.
