A comestible freezer of the type having a freezing barrel and a rotor in the barrel. The rotor has rigid flight bars extending in helical fashion along the inner surfce of the barrel and spaced inwardly therefrom, and a scraper blade of resilient plastic material is provided with a lengthwise extending channel to receive the flight bar so that the blade conforms to the helix of the flight bar. The scraper blade has two blade portions that extend in opposite directions from the channel and resiliently engage the inner surface of the freezing barrel to scrape frozen comestible from the freezing barrel and feed the comestible lengthwise of the barrel.
