The large chamber (2) is closed at the top, the small chamber (3) is open at the top and contains a sieve (5). Each chamber has a circular drain at the bottom. These are closed by covers (6,7), which are connected moveable via a lever system (8). The system is fastened in its pivot point and has two levers of different lengths. The cover for the large chamber is flat and circular, and closes it from the outside, while that for the small chamber is conical and closes it from the inside.
