French Fry TUNNEL FREEZERS
French Fry tunnel freezers
FPS French Fry Tunnel Freezers deliver high‑performance, hygienic freezing for modern potato processors. Using our Air Flow IQF technology, they gently separate and freeze each fry to preserve texture and quality.
Built with fully welded stainless‑steel enclosures, smooth TIG‑welded surfaces, and sloped, drain‑friendly floors, these freezers minimize harborage points and elevate sanitation—setting a benchmark in hygienic design.
External motors and gearboxes remain outside the freezing zone to improve cleanability and reduce maintenance demands. Engineered for uptime, FPS tunnel freezers deliver consistent performance essential for high‑capacity French fry production.
Features
External fan and thumper motors for easy access and improved sanitation
Fully welded stainless‑steel hygienic construction
Gentle, mechanically assisted fluidization for consistent product handling
Two‑ to three‑belt cascade for optimized cooling, reduced blow‑off, and oil congealing
Recirculating Clean-In-Pace (CIP system)
SynchroSD™ Sequential Defrost System for uninterrupted performance
Slip‑resistant sloped floors for effective drainage
Controlled Fluidization Air Flow Design
Controlled fluidization airflow uses radial fans and optional VFDs to deliver precise, gentle air movement that minimizes blow‑over. UHMW rotating thumpers keep product evenly separated while the open, low‑surface design and minimal baffles enhance hygiene and simplify cleaning. Efficient airflow, low pressure drop, and optimized fin spacing with sequential defrost work together to reduce energy use and maintain consistent freezing performance.
Variable Fin Coil Design
FPS coil design features variable fin spacing to reduce frost buildup, maintain airflow, and minimize blockage. Continuous fins and premium HD aluminum, CuNi, or stainless‑steel materials enhance durability while preventing debris flow. Compared to standard continuous‑fin coils that create higher pressure drops and require more fan power, FPS’s approach ensures better airflow efficiency and lower energy consumption.
