The apparatus comprises an evaporator (10) intended to evaporate and collect a solvent, and a source of vacuum (30) connected to the evaporator. The source of vacuum consists of a compressed air pump (31) without a motor, in which a partial vacuum is generated by the entry of compressed air through at least one ejector. A device (35) for regulating the flow rate of compressed air entering the pump (31) is provided in order to make it possible to adjust the pressure in the evaporator. <IMAGE>
