SZG series double cone rotating vacuum drier's main machine is double cone tank, let steam or heat water inside sealed jacket heat the inner shell in vacuum state, the hot transferred from inner shell to dump material, make water of the dump material gasify, low speed motor drying the tank along, make material up and down, from inside to outside, and change the heated surface, at the same time, vapour is taken out continually through vent-pipe of vacuum pump, increase the speed of drying, attain the purpose of uniformity drying at last, it is in conformity with the requirement of GMP.

SZG双锥回转真空干燥机主机为双锥形罐体，罐内在真空状态下，夹套内可通过内胆传递给湿物料，使湿物料中水分气化，低速电机带动罐体回转，物料不断上下内外翻动，更换受热面，同时，水蒸气通过真空泵经真空排气管不断被抽走，加快了物料干燥速率，最终达到均匀干燥的目的。符合药品管理规范&GMP&的要求。

The corresponding vacuum degree of condenser is called optimum vacuum or the most economical vacuum.

与此相应的凝汽器内的真空度称为最有利真空度或最经济真空度。

In the present work, based on the mechanism of low - temperature corrosion, an opinion was presented by theoretical analysis and computation, that is the vacuum boiler can not avoid being corroded completely under low temperature, but the corrosion is very weak no matter if the exhaust gas temperature is higher than the flue gas dew point; it was obtained the relationship between the corrosion velocity of metal wall and wall temperature along gas pass of vacuum boiler, and the one between the corrosion velocity of metal wall and wall temperature under the condition that the flue gas temperature is lower than the acid dew point.

文章从锅炉发生低温腐蚀的机理人手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；同时，文章推荐真空相变锅炉的设计排烟温度取130℃左右的低排烟温度。

本文从锅炉发生低温腐蚀的机理入手，通过理论分析计算并通过实践检验，提出了真空相变锅炉虽然不能完全避免低温腐蚀问题，但不论排烟温度是否高于烟气露点，低温腐蚀的程度都很弱的观点；给出了真空相变锅炉沿烟气流程金属壁面的腐蚀速度与壁面温度的关系曲线，和烟气温度低于酸露点时金属壁面的腐蚀速度与壁面温度的关系曲线；笔者专门从事真空相变锅炉的设计研究已十多年，根据上述观点设计的数百台产品已经过多年实际运行，未发现明显低温腐蚀。
