Abstract: An installation for the washing of vegetables, fruits or similar products comprising a cylindrical tank and a source of supply of water permitting not only the filling of the tank but also the driving of the mass of water in rotation around its vertical axis. This source of supply of water comprises at least one ramp arranged above the level of the water contained in the tank, the ramp being provided with holes which are directed downward and diagonally so that the jets which emerge therefrom strike the surface of the water and drive it in a movement of rotation.
