Liquid Egg Heat Exchangers

Sanitary Tube-in-Tube Heat Exchangers

Liquid egg processing requires heat exchangers that can handle viscous and protein-rich fluids while maintaining strict hygiene and preventing product degradation. Southwest Thermal’s sanitary-grade stainless steel tube-in-tube heat exchangers are engineered for these applications, offering exceptional corrosion resistance and compliance with 3A, FDA, and USDA hygiene standards. These units provide efficient heat transfer for processes like pasteurization, ultra-high temperature (UHT) treatment, and cooling of liquid egg products, including whole eggs, egg whites, and yolks, in the food and beverage industry.

Constructed from 316L stainless steel with polished surfaces (Ra = 32 µin), these exchangers prevent microbial growth and support Clean-in-Place (CIP) and Sterilize-in-Place (SIP) systems for rigorous hygiene. The tube-in-tube design, with its wide-flow paths and smooth surfaces, minimizes fouling and ensures gentle handling of delicate egg products to preserve texture, nutritional value, and safety. These exchangers are customized to manage high-viscosity fluids and protein content, with ASME and 3A certification available for industry compliance.

The compact and sanitary design of tube-in-tube heat exchangers makes them ideal for liquid egg processing, ensuring hygiene, product integrity, and efficiency in food production environments.

Heat exchanger operations for liquid egg processing involve several critical steps to ensure hygiene and product quality:

• Fluid Preparation: Liquid egg products are pre-treated to ensure consistent flow and compatibility with the exchanger, removing any impurities.
• Heat Transfer: The liquid egg flows through the inner tube, while a heating or cooling medium flows in the annular space, ensuring gentle and efficient heat transfer.
• Temperature Control: Precise regulation of temperatures prevents protein denaturation, coagulation, or flavor loss in sensitive egg products.
• CIP/SIP Integration: Automated CIP and SIP systems circulate cleaning agents or steam to maintain hygiene and prevent contamination.
• Testing: Post-process testing verifies product temperature, safety, and quality to meet food safety and industry standards.

Each stage relies on the precision and durability of stainless steel tube-in-tube heat exchangers to handle liquid egg products while maintaining efficiency, hygiene, and product quality.
