Overview
A Food-grade / Hygienic Heat Exchanger is a plate or tubular unit purpose-built to the cleanliness, surface-finish and traceability requirements of the food, beverage, dairy and pharmaceutical industries. All product-wetted surfaces are AISI 316L stainless steel with a controlled surface finish (Ra ≤ 0.8 μm or as specified), gaskets are FDA-compliant elastomers, and connections are sanitary clamp (Tri-Clamp), DIN 11851 or SMS as required.
Construction is designed for Clean-In-Place (CIP) and Sterilization-In-Place (SIP) without disassembly, with drain-free geometry on the product side and full traceability of plate and gasket lot numbers. Pasteurizers and UHT units are supplied as multi-section assemblies — regeneration, heating, holding and cooling — on a single skid.
Typical applications include milk and cream pasteurization, beverage cooling and pasteurization, brewery wort cooling, edible-oil heat treatment, sauce and condiment heat exchange, and aseptic/sterile duties in pharmaceutical and biotech plants.
