1. A manually-operated food processing appliance comprising:
a bowl to contain the food to be processed, with a side wall;
a removable rotary work accessory arranged in the bowl and having a drive shaft;
a removable lid arranged on the bowl, the removable lid comprising a manually-operated motor configured to cause the drive shaft to spin around a rotation axis A by pulling on a cord transversely to the rotation axis A,
wherein the lid comprises:
a first dynamic gasket arranged between the removable lid and the side wall of the bowl to fill the space between the removable lid and the bowl;
a second dynamic gasket, arranged between the removable lid and the drive shaft to fill the space between the drive shaft and the removable lid;
wherein each of the first and second dynamic gaskets has an inner wall, a connecting part arranged on the removable lid, an annular lip and a groove, the annular lip configured to be movable and deformable with a displacement angle α extending outwards relative to the rotation axis A, so as to ensure a watertightness when the removable lid is connected to the bowl in the working position.
