    Abstract: This invention concerns a juicer, that is a machine for extracting the juice from fruit and vegetables. Such machines are used domestically, and also commercially in restaurants, cafes and juice bars. The invention comprises an electric motor, a shredder mounted for rotation by the motor, a feed tube to deliver pieces to be juiced to the shredder for juicing, wherein the feed tube has an inner diameter of more than 75 mm, and three, or more, inwardly directed formations are arranged to constrict the interior of the feed tube. The inner diameter of the feed tube may be large enough for a typical apple to pass through it whole such as 85 mm or more. The inwardly directed formations serve to prevent the insertion of a hand or arm into or through the feed tube despite its large diameter.
