Product Specifications

Technical details and manufacturing context for Vacuum System

Definition
The vacuum system is a critical component of the Automated Pharmaceutical Lyophilization System, responsible for establishing and regulating the low-pressure environment required for freeze-drying. It removes air, water vapor, and other non-condensable gases from the product chamber, enabling the sublimation of ice from frozen pharmaceutical products under controlled conditions. This system ensures precise pressure control throughout primary and secondary drying phases, directly impacting product quality, drying efficiency, and cycle time. The system typically includes vacuum pumps (rotary vane or dry screw), vacuum gauges (Pirani, capacitance manometers), valves, and cold traps or condensers to capture sublimated water vapor. It maintains vacuum levels typically in the range of 10-1000 mTorr for efficient sublimation. Key parameters include ultimate vacuum (≤0.001 mTorr), pumping speed (100–500 m³/h), leak rate (≤1×10⁻³ mbar·L/s), operating pressure (1.0–1.6 MPa), chamber volume (0.5–5.0 m³), temperature range (-40–85 °C), power supply (380 ±10% V AC, three-phase, 50/60 Hz), ingress protection (IP54–IP65), material (SS316L), and weight (500–2000 kg). These values are reference ranges and must be verified for the specific model and application. The system is constructed with materials such as stainless steel (316L), fluoroelastomer (FKM/Viton), and PTFE (Teflon). Standards such as ISO 21360, IEC 60038, IEC 60529, and ASTM A240 are referenced for verification. Always confirm model-specific specifications and compliance with the legal manufacturer or supplier.
Working Principle
The system operates by using vacuum pumps (typically rotary vane or dry screw pumps) to evacuate the lyophilization chamber, creating a pressure differential. It may include components like vacuum gauges (Pirani, capacitance manometers), valves, and cold traps or condensers to capture sublimated water vapor, maintaining the required vacuum level (typically in the range of 10-1000 mTorr) for efficient sublimation.
