An experimental low damage sugarbeet cleaning screen was fitted with two types of polypropylene fiber brushes; one a rotating cylindrical brush and the other a flail type strip brush. Tests were conducted on the cleaning screen to compare the performance of brushing sugarbeets with that of conventional methods. Different speeds and configurations of the brushes were investigated for their damage and cleaning characteristics. It was found that the brushes left less residual dirt on the beets and caused less damage to the root's tissue than the conventional cleaning methods.
