A telescoping rotatable tool includes a first shaft and a second shaft. The first shaft has a first material-engaging element extending from an exterior surface of the first shaft. The second shaft has a second material-engaging element extending from an exterior surface of the second shaft. The second shaft is configured to extend from and retract within an interior space presented by the first shaft. The first shaft includes at least one helical-shaped groove extending along an interior surface of the first shaft. The second shaft includes at least one guide element extending from the exterior surface of the second shaft. The guide element is configured to engage with the groove, such that as the second shaft extends from and retracts within the first shaft, the second shaft is configured to rotate with respect to the first shaft.

An apparatus can include a hollow tube, central shaft, agitation components, and bidirectional fluted auger. The hollow tube can have an inlet, outlet, and longitudinal central axis, and can facilitate the conveyance of foodstuff materials from the inlet to the outlet. The central shaft can extend along the longitudinal axis and can be rotationally driven both clockwise and counterclockwise. The agitation components can be coupled to the central shaft and can agitate and mix foodstuff materials being conveyed along the hollow tube. The bidirectional fluted auger can be coupled to the central shaft proximate the outlet, can rotate with the central shaft when the central shaft is rotationally driven, and can have a flow rate limiting inner cylinder, clockwise-progressing flute features, and counterclockwise-progressing flute features. The clockwise and counterclockwise progressing flute features can convey foodstuff materials toward the outlet when the bidirectional fluted auger is rotated clockwise or counterclockwise.

Disclosed is a slurry drying plant (1) comprising a slurry inlet (2) for feeding slurry to the slurry drying plant (1) and two or more meshing screw conveyors (3, 4) arranged to at least partly divide the slurry while conveying the slurry in a transport direction from the slurry inlet (2) to a slurry outlet (5). The slurry drying plant (1) further includes slurry heating means (6) comprising means for passing superheated steam substantially at atmospheric pressure past the slurry and the two or more meshing screw conveyors (3, 4), while they are conveying the slurry. Furthermore, a method for drying slurry and use of a slurry drying plant (1) is disclosed.
