An apparatus for treating process material includes a vessel into which proc ess material can he introduced, an arrangement for introducing steam into the interior of the vessel to heat and impart moistur e to process material in the vessel, and several fluid t ransport conduits extending helically through the vessel for conveying heated fluid t hrough the vessel between opposite ends of the vessel in order to raise the temperature and pressure within the vessel to treat the materia l while also allowing the moisture content of the proces s material to be reduced. The fluid transport conduits are also configured to contact t he process material and assist in treating and densifyin g the material. The vessel can also be adapted to be pivoted so that the forward e nd of the vessel can be selectively positioned above and below a horizontal position. The vessel can also be interconnected with one or mor e similarly configured vessels to define a system for tr eating process material. The system can include an arrangement that allows steam an d heat from a hot vessel to be conveyed to a cold vessel . A method for treating process material can include introducing process materia l into two different vessels, raising the temperature wi thin one of the vessels through the introduction of steam to heat the material in the vessel, and reducing the temperature in the one vessel while also increasing the temperature in the other vessel by venting the interior of th e one vessel to the interior of the other vessel.
