Sterilization Nozzle Port

The Sterilization Nozzle Port is a component of an aseptic filling chamber, designed to securely mount and orient sterilization nozzles that deliver sterilants such as saturated steam, hydrogen peroxide vapor, or other media. It provides a sealed interface between the nozzle and the chamber, preventing contamination ingress while allowing precise delivery of sterilant to the chamber interior or specific surfaces, such as container interiors. The port ensures proper nozzle alignment, media flow direction, and integration with the chamber's sterilization control system. Constructed from materials like stainless steel 316L, PTFE, and silicone gaskets, the port is built for cleanability and corrosion resistance. Key parameters include a temperature range of -20 to 140°C, port sizes DN25–DN50 (ISO 1127), and a sanitary tri-clamp connection (ISO 2852). Surface roughness is ≤0.4 μm Ra (ISO 4287), and the seal material is EPDM (FDA 21 CFR 177.2600). The port supports a maximum flow rate of 10–20 L/min, weighs 0.5–1.5 kg, and has an IP65 rating (IEC 60529). These values are reference ranges and must be verified for the specific model and application. The port operates in sync with the chamber's automation, activating nozzles according to the sterilization protocol. It may include features for nozzle cooling or drainage post-cycle. Proper selection requires confirming compatibility with the sterilant type, chamber design, and control system. Verification questions should address pressure and temperature ratings, material certifications, and cleanability validation. Maintenance signals include seal degradation, leaks, or misalignment. Failure boundaries are defined by the specified pressure and temperature limits, beyond which seal integrity may be compromised. Always confirm model-specific values and standards with the legal manufacturer or supplier.

The port mechanically secures sterilization nozzles and connects them to media supply lines. During sterilization cycles, sterilant (e.g., saturated steam at 121–135°C, H2O2 vapor) is delivered through the nozzles via the port. The port's design maintains a seal to prevent leaks, directs the sterilant flow as required (e.g., laminar flow for surface coverage), and may include features for nozzle cooling or drainage post-cycle. It operates in sync with the chamber's automation, opening/closing or activating nozzles as per the sterilization protocol.
