  • Patent number: 4246700
    Abstract: A device for cutting out and extracting the pulp from a vegetable or fruit, particularly a pineapple, while leaving the peel or rind intact for later use. The device has a central coring tube depending from a handle and secured for rotation therewith. The coring tube enables the pulp to be severed from the hard, fibrous core of the fruit or vegetable as it is displaced axially. A vertically cutting blade also depends from the handle and is spaced radially from the axis of the device so that as the handle is rotated the cutting blade describes a cylindrical cut adapted to sever the pulp from a shell including the peel or rind. The device also comprises one or more radial cutting blades extending from the coring tube to the radial position of the vertical cutting blade depending on whether a cylindrical mass of pulp is desired or rather a stack of slices. A plurality of radial blades may be fixed to the coring tube.
