通常,多阶段真空泵用于低于 100 毫巴的吸入压力。为更高效地使用能量,两个阶段之间会对动力介质和可冷凝成分进行冷凝。
冷凝压力取决于冷却介质的温度与动力介质的特性。如果您使用水蒸汽作为动力介质且提供 25 °C 的冷却水,此压力大约为 60 毫巴。
表面冷凝器通常是中间冷凝器的首选,可以避免冷却水与吸入介质被污染。
Together with Mona Neubaur, Minister of Economic Affairs of the German state of North Rhine-Westphalia, GEA CEO Stefan Klebert has opened a new technology center for pharmaceutical freeze-drying systems in Elsdorf, Germany.
