    • 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.
    • 包含待蒸馏的液体Fd的湿材料的干燥方法使用耐过剩和/或负压的气密容器系统和连接干燥容器和冷凝器的干燥容器,冷凝器和蒸气室。 温度可调的干燥容器包含湿材料。 液体Fd在温度可调的蒸气室中转变为蒸汽。 冷凝器冷凝蒸气以产生冷凝产物。 监测和控制蒸气室中的压力,使得干燥和蒸馏总是在接近待蒸馏的液体Fd的饱和蒸汽压的范围内进行。 连续测定蒸气室中的压力和温度。 如果压力超过该范围的上限,则压力以这样的方式减少,特别是除去外来气体。

    • A technology can efficiently dry the high-boiling point solvent contained in the object and achieve the space-saving and energy-saving of a drying apparatus. A drying method for drying an object containing a first solvent while conveying the object into a chamber (38), comprises: a first drying step of drying the object up to a drying point in the prestage of the chamber (38); and a second drying step of forming a vapor atmosphere of a second solvent having a lower boiling point than the first solvent in the chamber (38) and drying the object such that the temperature of the object in an inlet port of the chamber (38) is made to be lower by a predetermined temperature difference than the temperature of the vapor atmosphere.
    • 一种技术可以有效地干燥包含在物体中的高沸点溶剂,并实现干燥装置的节省空间和节能。 一种干燥方法,用于在将物体输送到室(38)中的同时干燥包含第一溶剂的物体,包括:第一干燥步骤,将物体干燥至室(38)的前级处的干燥点; 以及第二干燥步骤,在所述室(38)中形成具有比所述第一溶剂沸点低的第二溶剂的蒸气气氛,并干燥所述物体,使得所述室(38)的入口中的物体的温度 使其比蒸汽气氛的温度低一个预定的温度差。
