ABSTRACT:
A spray treatment apparatus for small workpieces, for example for washing and rinsing, comprises several containers arranged for rotation about a common axis and each having an internal generally helical screw feed. Each barrel tapers from its intake end to its output end, which is disposed within the intake end of the next container, to feed workpieces directly. The axis is horizontal and the containers can be rotated independently. Spray heads carrying treatment liquid are spaced from the intake end of each container so that treatment liquid flows back in countercurrent to the workpieces to the intake end where it is collected at, filtered at and recycled to the spray heads.
