Sterilizer Tray Inserts | Withstands 300°C, Non-Deforming, Food-Safe Support Racks for Industrial Sterilizers

Sterilizer tray inserts (or racks) are essential internal components of industrial retorts, used to layer and support packaged products—such as glass bottles, tin cans, or flexible pouches—during thermal sterilization. Their design and material directly impact heat transfer efficiency, temperature uniformity, and process safety. Made from high-performance engineering materials, standard grades withstand continuous service from -40°C to +150°C, while specialty formulations (e.g., PEEK, modified PPS, or food-grade stainless-clad composites) endure short-term exposure up to 300°C. They deliver high compressive strength (≥80 MPa) and rigidity—remaining dimensionally stable under full load to maintain consistent layer spacing. Perforated or grid designs optimize fluid dynamics, improving steam/water penetration by 20–30% for more uniform sterilization. Smooth, crevice-free surfaces comply with FDA 21 CFR and EU 10/2011 for food contact—non-toxic, low extractables, and non-biofouling. Resistant to pH 1–14 cleaning chemicals and compatible with CIP/SIP cycles. Weighing only 1/5–1/3 of metal alternatives, they reduce operator fatigue and equipment stress. Modular design enables quick reconfiguration for different container types and sterilization methods (water bath, steam, spray). Proper selection can boost sterilization efficiency by 15–25%, cut energy use by 10–20%, and eliminate risks of product tipping or bursting due to rack deformation—making them a reliable foundation for smart sterilization systems.
