Process for dehydrating water-containing organic solid material which comprises steps of introducing the material into a pressure vessel, applying saturated steam to said vessel to heat the material so that water in the material is removed and mixed with condensate of the steam to be exhausted from the vessel as a waste water. The waste water is transferred to another pressure vessel in which the material is not charged yet, the material being then charged into the vessel to carry out the same dehydrating steps. According to the process, a sufficient amount of heat exchange is performed between the material and the waste water so as to recover the heat in the waste water. Further, the waste water functions as a cushion for the material which is being thrown into the vessel so that the material can be protected from being pulverized.

Dehydration process for organic solid material

A process for dehydrating water-containing organic solid material which comprises steps of introducing the material into a pressure vessel, applying saturated steam to said vessel to heat the material so that water in the material be removed and mixed with condensate of the steam to be exhausted from the vessel as a waste water. The process is characterized by a step of charging material of relatively large particle size at a bottom portion of the vessel and of relatively small particle size on the material of large particle size. The process makes it possible to dehydrate relatively fine particles of material by utilizing liquid form dehydration phenomemon.
