Abstract

A dehydrating apparatus (10) includes a chamber (12) for receiving wet material to be dehydrated. A rotatably-mounted agitator (26) is provided with the chamber (12). The agitator (26) is adapted to agitate material in the chamber when the agitator rotates in a first direction (28) and convey the material out of the chamber when the agitator rotates in the other, second direction (30).
