All Spaceman USA machines utilize Scraper Blades to produce soft-serve or frozen beverage product. These scraper blades attach to the beater / auger inside the freezing cylinder. This updated blade helps improve machine performance, helps reduce freeze ups on soft serve machines, and is more rigid than prior V1 blades for better scraping performance and better product quality. We refer to these scraper blades as Version 2 (V2). V2 blades are not backwards compatible with V1.
