Safety Rupture Disc
Product Model: ZD-020 (Food & Beverage Compliant)
Material: 316L Stainless Steel, all wetted parts. Electropolished (Ra < 0.8 μm) finish standard.
Compliance: Materials comply with FDA 21 CFR, EU Regulation 1935/2004. Design supports cleanability.
Key Feature: Smooth, crevice-free internal surfaces to prevent bacterial harborage.
Connections: Sanitary clamp (Tri-Clover) or ISO flange connections available.
Typical Use: Beer and wine fermenters, dairy processing tanks, juice storage vessels, and CIP/SIP systems.
Overview
In food, beverage, and dairy processing, product safety and quality are paramount. This rupture disc is engineered to integrate seamlessly into hygienic process lines. Manufactured from FDA-compliant 316L stainless steel with an electropolished finish, it presents no crevices or rough surfaces where microbes could hide. Suitable for Clean-In-Place (CIP) and Steam-In-Place (SIP) procedures, it provides reliable overpressure protection without compromising the hygienic integrity of your process.
Features & Benefits
Hygienic by Design: Smooth, polished internal contours and radiused corners meet EHEDG and 3-A Sanitary Standards principles for cleanability.
Material Compliance: All materials in contact with the product are FDA-listed and suitable for food contact.
CIP/SIP Compatible: Can withstand typical cleaning and sterilization cycles when pressure and temperature limits are observed.
Quick-Connect Fittings: Sanitary clamp connections allow for easy installation, inspection, and replacement.
How It Works
It functions as a standard forward-acting, pre-scored rupture disc. The bursting membrane is designed to open fully and cleanly. The primary focus is on the materials and surface finishes of the holder and the integration of the disc to ensure the assembly maintains its hygienic properties before and after activation.
Specifications (Descriptive)
Common sanitary pipeline sizes: 1.5", 2", 3", 4" Tri-Clamp and DN50, DN80, DN100 ISO flanges. Burst pressures are typically low, suited for fermentation and storage tanks (e.g., 0.5 to 2.5 barg). The standard membrane material is 316L SS. For aggressive products like acidic juices, a PTFE-faced composite version is available. All gaskets are platinum-cured silicone or EPDM. Documentation can include a Material Declaration and Certificate of Conformity.
Q&A
Q: How do I know if the disc is intact without opening the line?
A: You can specify an external burst indicator (a mechanical pin that pops out) or an electronic sensor with a hygienic housing. These provide visual or remote signals without breaching the system.
Q: Can this disc be used in aseptic (sterile) processing?
A: The design supports aseptic requirements due to its cleanability and steam sterility. For critical aseptic applications, specific validation support and potentially a sterile-ready packaging option would be required.
Q: What is the recommended replacement schedule?
A: Follow a preventive maintenance schedule based on the manufacturer's recommendation (often 12-24 months) or align with major plant CIP/overhaul schedules. Always replace after any SIP cycle that exceeds the disc's temperature rating or after activation.
