  • Patent number: 7954425
    Abstract: To improve the efficiency of juice-extracting food processors (1) based on grating fruit or vegetables, wherein the inlet piece (2) forms an interstice (I) with the grating disk (3), interstitial cutting teeth (302) are arranged in the interstice (I). Pieces of fruit or vegetables in the interstice (I) are additionally accelerated in the direction of the sieve 151 due to centrifugal forces by the interstitial cutting teeth (302) acting on these pieces. The juice contained in these pieces is thus more efficiently extracted. For better processing of pieces of fruit or vegetables with a high juice content, the interstitial cutting teeth (302) are preferably higher than the other cutting teeth (301) of the grating disk (3).
