  • Device and Method for Removing the Core of a Plant
    Publication number: 20090249630
    Abstract: A device and method for removing the core of a plant. This device consists of a tubular part which does not form a completely round circle, but only extends over approximately 180° (i.e. semi-circular arch). This tubular part is provided with a cutting section at one free end, thus making it possible to remove a core part of a plant. On the opposite end, the device is provided with a cutting section which does form a complete continuous circle, thus making it possible to remove an entire core of a plant such as lettuce.
