上海延安制药厂从西德进口了两台软胶囊机进行流水生产。其软胶囊的成型和烘干是在低温(烘房温度维持在25℃左右,与蒸汽加热相比可说是低温)和低湿(相对湿度小于35％)环境中进行的,可保证全年生产。但原设计采用二级冷冻除湿不能达到工艺所需的空气参数,生产不能正常进行,所以,于1983年2月作了改造设计,并于5月施工完毕投入了生产,基本上达到了要求。现将该工程情况简介如下。
Shanghai Yan’an Pharmaceutical Factory imported two soft capsule machines from West Germany for flow production. The formation and drying of its soft capsules are performed at low temperatures (the temperature of the drying chamber is maintained at about 25°C, compared with the steam heating can be said to be low temperature) and the low humidity (relative humidity is less than 35%), and the production can be guaranteed throughout the year. . However, the original design used two-stage freezing and dehumidification to achieve the air parameters required for the process, and the production could not be carried out normally. Therefore, a retrofit design was made in February 1983, and production was put into production in May, basically meeting the requirements. The project profile is as follows.
