LYOMAC Freeze Dryer is specially designed for API (Active Pharmaceutical Ingredient) development and is equipped with automatic filling function, suitable for the production needs of pharmaceutical companies in Xiamen and other regions. The equipment can flexibly switch operating modes; it can start the automatic freezing program without turning on the automatic freeze-drying function, realizing full-process automatic operation. At the same time, the equipment supports dilution protection function, and the liquid medicine does not contact air or oxygen at all during the entire production process, effectively avoiding oxidative pollution and ensuring the purity and activity of API. In addition, the equipment can be equipped with a product liquid storage tank, an automatic pumping system and an automatic conveying flow sensor, realizing full-process automatic control from liquid medicine storage, conveying to filling and freezing, greatly improving production efficiency, reducing manual intervention, ensuring the stability and compliance of the production process, and providing a safe, efficient and intelligent solution for API production.
