| titleOfInvention | A kind of cilastatin separation and purification system |
| abstract | The utility model discloses a cilastatin separation and purification system, which comprises a series-connected first-stage membrane filter, a second-stage membrane filter, and sending a concentrated solution containing cilastatin into a first-stage membrane filter, a second-stage membrane filter, and a second-stage membrane filter. The second water pump of the membrane filter, the feed liquid outlet of the first-stage membrane filter and the second-stage membrane filter are connected in series or in parallel with the third-stage membrane filter through pipelines, and the feed-liquid outlet of the third-stage membrane filter is passed through the feed liquid The pipeline is connected to the finished product liquid tank; the dialysate outlet of the first-stage membrane filter, the second-stage membrane filter, and the third-stage membrane filter is provided with a dialysate outlet pipe, and the dialysate outlet pipe is connected with a parallel pipeline so that One of the pipelines is connected to the waste liquid collection tank, so that the other pipeline forms a circulation pipeline and is connected to the CIP tank through the circulation pipeline, and the outlet of the CIP tank is connected to the liquid inlet pipeline of the second water pump. This system realizes the separation and purification of cilastatin, ethanol and water. |
