Abstract
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.
