process and device for solvent removal under reduced pressure. The invention provides a continuous process for removing organic solvents from a cake comprising the steps of: (a) introducing said cake continuously into a cake remover； (b) introducing an inert gas separation means for said solvent remover； (c) removing said one or more organic solvents from said bagasse by maintaining a sub-atmospheric pressure within said bagasse remover, thereby providing a solvent-removed organic material； and (d) continuously extracting said removed solvent organic material removed from said solvent remover, wherein step (a) and step (d) comprise compacting said bagasse and said solvent organic material removed to a first and a second one. second substantially gas impermeable plastic masses respectively and extruding both said first and said second plastic masses through an annular space whose opening is controlled by the rate of supply of said first and second plastic masses. The invention also provides a device for compacting a wet organic material to a first gas impermeable plastic mass that is useful for implementing this process.processo e dispositivo para retirada de solvente sob pressão reduzida. a invenção fornece um processo contínuo para remover solventes orgânicos de um bagaço compreendendo as etapas de: (a) introduzir dito bagaço de maneira contínua em um removedor de bagaço； (b) introduzir um meio de separação gasoso inerte para dito removedor de solvente； (c) remover dito um ou mais solventes orgânicos de dito bagaço mantendo uma pressão sub-atmosférica dentro de dito removedor de bagaço, fornecendo assim um material orgânico com solvente removido； e (d) extrair de maneira contínua dito material orgânico com solvente removido removido de dito removedor de solvente, no qual a etapa (a) e a etapa (d) compreendem compactar dito bagaço e dito material orgânico com solvente removido para uma primeira e uma segunda massas plásticas substancialmente impermeáveis a gás, resp
