LYOMAC: Ensuring Excellence in Quality, a Commitment to Fully Meet Customer Needs Before Delivery
In the pharmaceutical industry, equipment quality and regulatory compliance are the cornerstones of product safety and production efficiency. LYOMAC understands the critical role its freeze dryers play in customers’ production processes. Therefore, we consistently adhere to the principle of “Quality First, Compliance Above All” throughout the entire lifecycle of our equipment, especially during pre-delivery testing and validation. LYOMAC promises that every freeze dryer delivered from our factory undergoes the most rigorous testing and comprehensive validation to ensure outstanding performance and full compliance with customers’ User Requirement Specifications (URS) and international regulations.
Before delivery, LYOMAC freeze dryers undergo a series of systematic and rigorous tests. One of the most important steps is inviting customers to our factory for FAT (Factory Acceptance Test). This is not only a performance inspection but also a transparent collaboration process, ensuring customers have a thorough understanding of the equipment before it is put into operation.
During the FAT process, LYOMAC’s professional team works with customer representatives to verify the following key performance aspects:
Vacuum Integrity and Performance Verification of the Chamber: This is fundamental to the proper functioning of the freeze dryer. We conduct stringent leak tests to ensure the freeze-drying chamber maintains a perfect seal under extreme vacuum conditions. Additionally, we thoroughly inspect the performance of the shelf heating and cooling systems, as well as the condenser refrigeration system, to ensure temperature control range, cooling rate, refrigeration efficiency, and other parameters meet design requirements.
Shelf Temperature Uniformity Validation: This is critical to the success of the freeze-drying process. Using multi-point sensors, we precisely monitor temperature distribution across all freeze-drying shelves at different temperature setpoints, ensuring compliance within the strict standard of ≤±1°C. We also verify shelf flatness to ensure consistent heat transfer for every vial, guaranteeing product quality uniformity.
CIP Cleaning Validation: We validate that the automatic Clean-in-Place (CIP) system efficiently and thoroughly cleans the freeze-drying chamber and all internal pipelines. Through spray coverage tests, residual detergent detection, and microbial sampling, we confirm that the cleaning effectiveness meets the expected cleanliness standards, fulfilling the requirements for sterile production.
SIP Sterilization Validation: For freeze dryers used in sterile production, we conduct comprehensive validation of the Steam-in-Place (SIP) function. This includes monitoring and recording key parameters such as temperature, pressure, and time to ensure the entire sterilization cycle meets the predefined F0 value. This verifies the equipment’s ability to reliably achieve a sterile state, ensuring product safety.
In addition to detailed performance testing, LYOMAC provides comprehensive validation documentation and support, which are essential components of pharmaceutical equipment compliance. These documents and tasks include:
IQ (Installation Qualification): Confirming that the equipment is installed correctly according to design specifications and manufacturer recommendations.
OQ (Operational Qualification): Verifying that the equipment operates as intended within specified operational ranges and validating the control accuracy of all critical parameters.
PQ (Performance Qualification): Confirming that the equipment can consistently produce products meeting predetermined quality standards under simulated or actual production conditions.
CSV (Computerized System Validation): Validating the software functionality, data integrity, audit trails, and user management of the PLC and SCADA control systems to ensure compliance with FDA 21 CFR Part 11, EU Annex 11, and GAMP5 requirements.
Other validation checks as required by the customer in the URS. LYOMAC works closely with customers to ensure all critical points are thoroughly validated.
Through the rigorous FAT acceptance testing and comprehensive validation documentation review, LYOMAC ensures that every freeze dryer fully meets the customer’s URS (User Requirement Specifications) and all relevant regulatory requirements, such as cGMP, FDA, and EU GMP, before shipment. This unwavering commitment to quality and compliance is the foundation of LYOMAC’s trusted reputation and its role as a reliable global partner in the pharmaceutical freeze-drying industry.
