Sterile Product Tank Interface for Aseptic Filling Machines

Product Specifications

Technical details and manufacturing context for Sterile Product Tank Interface

Definition

The Sterile Product Tank Interface is a critical component in aseptic filling machines, providing the connection point between the sterile product storage tank and the machine's filling system. It ensures sterile transfer of pharmaceutical, biotech, or food products while maintaining aseptic conditions throughout the filling process. The interface creates a sealed connection, typically using sterile connectors or aseptic transfer systems, and maintains sterility through positive pressure, sterile barriers, or steam-in-place (SIP) connections, preventing contamination during product transfer. This component is designed for use in industries requiring high levels of hygiene and contamination control. It is available in connection sizes from DN25 to DN100 (ISO 1127) to match the filling machine inlet flange. Operating pressure ranges from 1.0 to 1.6 MPa, with a note that Operating temperature spans from 10°C to 150°C, with SIP up to 150°C. Product contact surfaces have a surface roughness of ≤0.4 μm Ra (ISO 4287). The leakage rate is ≤1×10⁻⁶ mbar·L/s (ISO 15848-1, helium leak test). Materials on file include Stainless Steel 316L (electropolished, ASTM A270), pharmaceutical-grade silicone, and PTFE. Weight ranges from 2.5 to 15 kg depending on size and configuration. For electrical components, ingress protection is IP65 (IEC 60529), and electrical supply for sensors/actuators is 24 V DC ±10%. When selecting this interface, verify model-specific values and standards with the legal manufacturer or supplier. Confirm that the connection size matches your filling machine, operating pressure and temperature are within your process limits, and that materials are compatible with your product. Regular maintenance should include inspection of seals and sterile barriers, and monitoring for leaks. Failure boundaries include loss of sterility, leakage, or material degradation. Always consult the manufacturer for detailed specifications and validation data.

Working Principle

The interface creates a sealed connection between the product tank and filling system, typically using sterile connectors or aseptic transfer systems. It maintains sterility through positive pressure, sterile barriers, or steam-in-place (SIP) connections, preventing contamination during product transfer. The design ensures that the product path remains sterile from the tank to the filling nozzles, with all wetted parts made of compatible materials. The interface may include sensors and actuators for monitoring and control, powered by a 24 V DC supply. Proper installation and maintenance are essential to preserve the sterile barrier and prevent leaks.
