Sanitary Tube-in-Tube Heat Exchangers
Processing fluids containing fibers or slurries presents unique challenges, requiring heat exchangers that prevent clogging while maintaining efficient heat transfer. Southwest Thermal’s sanitary-grade stainless steel tube-in-tube heat exchangers are engineered for these applications, offering exceptional corrosion resistance and compliance with hygiene standards like 3A and FDA. These units are ideal for handling viscous fluids with fibrous materials or slurries in industries such as food and beverage processing, pulp and paper production, chemical processing, and wastewater treatment.
Constructed from 316L stainless steel with polished surfaces (Ra = 32 µin), these exchangers prevent microbial growth and support Clean-in-Place (CIP) systems for easy cleaning. The tube-in-tube design, with its wide-flow paths and smooth surfaces, minimizes fouling and ensures reliable performance with high-viscosity or fibrous fluids. These exchangers are customized to handle specific fiber and slurry compositions, with ASME and 3A certification available for industry compliance.
The compact and robust design of tube-in-tube heat exchangers makes them ideal for processing fibers and slurries, ensuring hygiene, durability, and efficiency in demanding sanitary and industrial environments.
Heat exchanger operations for fibers and slurries involve several critical steps to ensure efficiency and hygiene:
- Fluid Preparation: Fibrous fluids or slurries are pre-treated to ensure compatibility with the exchanger, adjusting viscosity or particle size as needed.
- Heat Transfer: The process fluid with fibers or slurries flows through the inner tube, while a heating or cooling medium flows in the annular space, ensuring efficient heat transfer.
- Temperature Control: Precise regulation of temperatures prevents degradation of fibrous materials or clogging due to overheating or overcooling.
- CIP Integration: Automated CIP systems circulate cleaning agents to remove residues and maintain hygiene without disassembly.
- Testing: Post-process testing verifies fluid temperature, purity, and quality to meet industry standards.
Each stage relies on the precision and durability of stainless steel tube-in-tube heat exchangers to handle fibers and slurries while maintaining efficiency and hygiene.
