摘要： The invention relates to a method for drying a wet material (4) which comprises a liquid Fd to be distilled, using a gas-tight container system (1) that is resistant to excess and/or negative pressure. Said container system comprises a drying container (2) containing the wet material (4) whose temperature can be adjusted, a condenser (3) for condensing the liquid Fd, which has turned to vapor and whose temperature can be adjusted, to give the condensation product (5), and a vapor chamber (6) connecting the drying container (2) and the condenser (3). The aim of the invention is to make sure that the vapor in the vapor chamber (6) is free of foreign gas except for a tolerated remainder. To achieve this aim, the pressure in the vapor chamber (6) is monitored and controlled in such a manner that drying and distillation are always carried out in a range close to the saturation vapor pressure of the liquid Fd to be distilled. For this purpose, the pressure and the temperature in the vapor chamber (6) have to be continuously determined. If the pressure is too high, it is reduced in such a manner that especially foreign gas is removed.
