<p>A longitudinal sliding plane (42) is defined on a framework (20) along which the crates are slidably arranged upside down. A truck is slidable in a direction parallel to the plane (42) under control of a pneumatic cylinder (40), and is provided with pushers (52, 56) for pushing the crates. An inside washing device (68) comprises a first delivery member which is pivotally supported below the sliding plane, is provided with nozzles (80, 82) shooting upward water jets, and is driven to rotate by the cylinder via trasmission means (58, 77) which turn the motion of translation of the truck (38) into a rotary motion. An outside washing device (102) comprises a delivery member supported above the sliding plane and provided with nozzles (116, 118) shooting lateral water jets. A hydraulic circuit (CI) connectable to pressurized fluid supplying means (P) supplies both the washing devices.
