Apparatus for treating biologically retted plant stems includes a longitudinally oscillating distributor that transfers the stems from a first conveyor to a second conveyor. The stems are arranged transversely to form a layer on the first conveyor. Apparatus for treating biologically retted plant stems includes a longitudinally oscillating distributor that transfers the stems from a first conveyor to a second conveyor. The stems are arranged transversely to form a layer on the first conveyor. The distributor may have two parallel conveyor belts each passing around an upper and a lower roller. The axis of each upper roller is stationary. The axes of the lower rollers pivot relative to the upper axes. This distributes the stems across the second conveyor so that the stems are equally spaced. The retting takes place in a cylindrical tank. The stems are bundled so their stems are parallel to the main axis of the tank. A treatment liquid is sprayed onto the bundles from nozzles on a rotating radial arm with a depending skirt. While on the first conveyor unwanted material is removed from the stems by passing between upper and lower sets of fluted cylinders.
