Automated bin washer

A method of washing and sanitizing bins, the method comprising the steps of:

• loading a plurality of bins onto a bin rotator having at least one bin holder, the bins being loaded on the bin rotator at a first predetermined upright position;
• rotating the bin rotator upward relative to the ground at a first predetermined angle of rotation to allow the bins to slide and then flip off the bin rotator for allowing said bins to be loaded onto a first conveyor platform disposed in an infeed conveyor zone, the bins being loaded on the first conveyor platform at a second predetermined inverted downward position;
• transporting the bins disposed in the second predetermined inverted downward position from the first conveyor platform in a conveying direction onto a second conveyor platform, the second conveyor platform being disposed in a bin washer zone;
• washing and sanitizing the bins disposed in the second predetermined inverted downward position in the bin washer zone with a pressurized liquid flowing from a plurality of sprayers;
• providing an outfeed zone comprised of a first and a second horizontal roller bar arranged in longitudinal columns and configured to spin via gravitational energy, the outfeed zone being disposed at a third predetermined angle directly above the ground to allow the bins to be transported via gravitational and kinetic energy in the conveying direction;
• flipping and transferring the bins into the outfeed zone by causing the bins to pivot about the first horizontal roller bar to the second horizontal roller bar such that the bins are inverted to the first predetermined upright position;
• and
• transporting the bins into a loading position at the end of the outfeed zone.
