Abstract

Abstract A continuous washing apparatus is provided which comprises an elongate washing vessel 1 having an inlet 2 for receiving objects to be washed at one end thereof. An outlet 3 is provided for discharging objects W to be washed at the other end thereof. The elongate washing vessel is arranged in an inclined manner so that the inlet is located downwardly and the outlet is located upwardly. A conveyor is disposed within the washing vessel for conveying the objects from the area adjacent to the inlet toward the area adjacent to the outlet. A washing structure 14 15 is provided for washing the objects. The conveyor includes a screw body 4 rotatably mounted on the washing vessel 1, and a drive mechanism for driving the screw body. The screw body includes a continuous length of fin 5 which extends helically around the longitudinal axis of the washing vessel. Brush members 6 are attached to the fin for brushing the objects and a central bore extends through the central portion of the screw body along the longitudinal axis thereof.
