The operation of Freeze Dryers is a ‘black art’ to many people, and so it is perhaps very surprising and a credit to Optimal to have automated perhaps 10 or more Freeze Dryers. It is fair to say that all the systems supplied have to date had a high level of automation and control with Client Server SCADA systems at the front end, however we could use our in-depth knowledge to build control systems using more basic controls if so required. In order to optimise productivity data historians have been used to capture Critical to Quality parameters. These have been used together with Overall Equipment Effectiveness (OEE) systems to ensure the maximum productivity per dryer.
We are fully conversant with all the normal controls functionality associated with Freeze Dryers, and can develop a controls strategy with the minimum of client input.
Due to the inherent nature of freeze dryers, our standard offer targets a high level of automation for a single system where we use a control system with a single SCADA interface on the system, this offering full automatic as well as manual control. The system has a recipe system together with historic and real time trending plus data logging for batch reports.
