Frequently Asked Questions About Freeze Dryers

Are SED Pharma freeze dryers suitable for pharmaceutical GMP production?

Yes. The SED-FDG series of production-scale freeze dryers is specifically designed and manufactured to meet the requirements of pharmaceutical GMP environments. These units feature 316L stainless steel product-contact surfaces, integrate comprehensive Clean-in-Place (CIP) and Sterilize-in-Place (SIP) capabilities, and are equipped with a validated PLC control system featuring electronic batch records and audit trail functions, all aimed at assisting users in achieving regulatory compliance.

What is the difference between pharmaceutical freeze dryers and food freeze dryers?

Pharmaceutical freeze dryers are specifically designed to facilitate sterile processing under strict GMP regulations; their features include the use of 316L stainless steel, integrated CIP/SIP systems, and validated, regulatory-compliant control software. In contrast, while food freeze dryers are equally robust and durable, their design prioritizes maximizing throughput and cost-efficiency rather than meeting sterile processing requirements; they typically utilize 304 stainless steel, feature simplified cleaning procedures, and employ standard PLC control systems, without the need for the extensive and rigorous validation documentation required in the pharmaceutical industry.

How do I choose the right freeze drying area for my lab?

Choose your model based on your typical batch size. For small scale experiments or formula screening, 0.1 – 0.5 m² models like the SED-0.2XDG or SED-0.3XDG‑Z are ideal. For small batch production or process optimization before scale‑up, the 1 – 2.25 m² models provide the extra capacity needed.

What freeze dryer size or shelf area do I need for my production volume?

Shelf area requirements depend on tray loading density, fill volume, and desired batch cycle time. As a general reference, our production freeze dryers range from 5 m² to over 216 m² of shelf area. We recommend sharing your target batch size and container specifications with our engineering team for a precise sizing recommendation.

Do you provide IQ/OQ documentation?

Yes. SED Pharma provides comprehensive validation documentation packages for all production freeze dryers, including Installation Qualification (IQ) and Operational Qualification (OQ) protocols to streamline your regulatory submission process.

Can SED Pharma provide a complete freeze drying line?

Yes. In addition to freeze dryers, we supply integrated solutions. For example, vial filling lines, stopper placement stations, and automatic loading/unloading systems. Our engineering team can design solution of a fully coordinated aseptic freeze drying line tailored to your facility layout and production capacity.
