Bin washer device with rotating bin holder and method of washing bins

A bin washer device for washing bins comprising:

• a conveyor for moving the bins in a conveying direction;
• a support frame disposed adjacent the conveyor and having a central axis of rotation;
• at least two bin holders attached to the support frame and rotatable about the central axis of rotation of the support frame, wherein at least one of the bin holders is configured to remove a bin from the conveyor and invert the bin by moving the bin relative to the conveyor,
• a plurality of outer sprays disposed outside a path of the bin holders and each positioned at a predetermined angle relative to a vertical direction perpendicular to the central axis of the support frame,
• wherein the central axis of the support frame extends parallel to the conveying direction of the conveyor,
• wherein the plurality of outer sprays includes a plurality of upper outer sprays disposed at a first position and a plurality of lower outer sprays disposed at a second position below the first position,
• wherein each of the upper outer sprays corresponds to one of the lower outer sprays and the angle of the upper outer sprays is offset by 90 degrees from the angle of the corresponding lower outer spray, and
• wherein:
• the plurality of upper outer sprays includes a left upper outer spray and a right upper outer spray,
• the plurality of lower outer sprays includes a left lower outer spray and a right lower outer spray,
• the angle of the left upper outer spray is a mirror-image of the angle of the right upper outer spray,
• the angle of the left lower outer spray is a mirror-image of the angle of the right lower outer spray,
• whereby as the bin holder rotates a bin the sprays spray alongside plural surfaces of the bin.
