Notes
① Before processing, ensure that screw, barrel and hopper are thoroughly cleaned, and impurities are strictly prohibited in the 3 processes of processing.
② Once the raw materials are opened, it is recommended to use them within 24 hours. If the package is damaged, it should be dried before use.
