ABSTRACT:
A tunnel-type batch washing machine has an outer tunnel-forming housing tube centered on a horizontal axis and provided internally with a helical wash screw rotatable in the tube about the axis and having a plurality of flights defining axially spaced compartments. A generally cylindrical sleeve is fixed to this screw and is coaxially received within the tube between the screw and the tube. A treatment liquid is flowed axially in one direction through the housing and respective batches of articles to be washed are held in the compartments between the flights. For washing the screw is oscillated back and forth about the axis through substantially more than 360.degree. to agitate the articles in the liquid. Periodically the screw is rotated about the axis through substantially more than 720.degree. in a rotation direction to advance the batches axially opposite the direction of liquid flow. The sleeve is formed at one of the compartments with a throughgoing aperture and the tube has in radial alignment with this one compartment a pocket provided with a heating apparatus. As the aperture is rotated into alignment with the pocket, liquid exchange takes place through the aperture to heat up liquid inside the sleeve.
