Abstract: An apparatus for the discontinuous preparation of portioned pasta products, in particular spaghetti, with a supply container to receive the raw products, a cooking chamber (1) and a draining chamber (2), wherein the cooking chamber (1) and the draining chamber (2) can each be closed by valves in their inlet region (1E, 1A) and outlet region (2A), the overall height of the apparatus being kept small by constructing the valves in the inlet region (1E) of the cooking chamber (1) and the outlet region (2A) of the draining chamber (2) as shut-off flaps (3, 4) that can be moved linearly in a direction transverse to the inlet and outlet direction and are spaced apart from the chamber wall containing the respective opening (1E, 2A) during this movement, and that to close the openings at the end of the linear movement, the shut-off flaps (3, 4) are pressed against the respective chamber (1, 2) in a direction perpendicular to the plane of the opening by means of a lever mechanism (36, 37A, 37B).
