| description | The invention relates to a technique for producing medicinal mirabilite by continuous crystallization. An on-line infrared computer automatic monitoring system is used for monitoring, and a porous plate liquid balance flowmeter is used for regulation and control, thereby ensuring that the manufacturing process, production facility and product of the medicinal mirabilite satisfy the GMP requirements. The technique comprises the following steps: when the indoor air cleanliness of the production workshop achieves the following indexes: the floating bacteria is less than 100 cfu/m , the sedimentated bacteria is less than 50 cfu/4 hours, the contact disc of the surface microorganism is less than 25 cfu/disc, the number of suspended particles which is more than 0.5 mu m is less than 350000/m , and the number of suspended particles which is more than 5 mu m is less than 2900/m , thus removing mechanical impurities from the downhole-transmitted original mirabilite solution with certain concentration through a three-l |
