  • Patent number: 4818297
    Abstract: To remove solvents such as alcohol from bulk material the solvent-laden bulk material is intensively loosened mechanically into a virtual fluidized bed through which a liquid in gaseous phase such as steam is passed so that the solvent having a lower boiling point than water is expelled from the bulk material and is evacuated with excess steam while at least part of the steam condenses on the particles of the bulk material which thereby is humidified. The solvent expelled from the bulk material is separated from the steam and can be used again. The treatment is carried out in a closed vessel in which the bulk material and the steam are moved relative to each other.
