As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. specializes in the production of high-quality heat exchange solutions for the dairy industry. Our Plate Heat Exchanger for Dairy Whey Cooling, constructed from premium 316L stainless steel and rated for 20 Bar operating pressure, delivers exceptional thermal efficiency and hygienic performance. Designed with a sanitary, easy-to-maintain structure, this heat exchanger is the ideal choice for processing whey in cheese, yogurt, and milk powder production lines, ensuring product safety and operational reliability.
The sanitary design of our plate heat exchanger meets the strictest hygiene standards required in the dairy industry. All product contact surfaces are made of 316L stainless steel, which offers superior corrosion resistance to acidic whey components. The gasketed plate configuration allows for easy disassembly, inspection, and cleaning, significantly reducing downtime and maintenance costs. With a working pressure capacity of 20 Bar, this heat exchanger is well-suited for high-pressure cooling applications, delivering consistent outlet temperatures and minimizing product degradation.
Key Features & Technical Specifications
- Material: 316L stainless steel plates and frames – excellent resistance to pitting and crevice corrosion in whey environments.
- Pressure Rating: 20 Bar (290 psi) – suitable for high-pressure cooling circuits.
- Design: Fully gasketed plate pack – easy to open, inspect, and replace gaskets.
- Sanitary Connections: Standard sanitary clamp connections (1.5" to 4") or optional flanges – meets 3A and EHEDG guidelines.
- Gasket Material: EPDM (standard) or NBR (optional) – food-grade, FDA-compliant.
- Temperature Range: -10°C to +150°C (depending on gasket selection).
- Flow Configuration: Counter-current flow for maximum heat transfer efficiency.
- Plate Thickness: 0.5 mm to 0.8 mm – optimized for strength and heat transfer.
