Core Engineering & Performance Advantages
Premium High-Pressure Insulation System
The heat-insulating storage enclosure is constructed from premium double-surface stainless steel polyurethane (PU) sandwich panels. The interior rigid core is filled and foamed by an imported high-pressure foaming machine under extreme pressure, providing uniform density, eliminating cold bridges, and drastically lowering thermal leakage to optimize energy efficiency.
Heavy-Duty Transmission & Stepless Regulation
The product conveyor utilizes a transmission mesh belt crafted from premium food-grade 304 stainless steel spring wire or wear-resistant POM, delivering a flawlessly smooth surface and an extended industrial service life. Driven by an imported high-performance frequency converter, the system provides precise stepless speed regulation to easily adapt to varied product freezing cycles.
Smart Control & Automated CIP Hygiene
The system features an intuitive 304 stainless steel PLC touchscreen control box with preset product profiles and real-time safety loop tracking. To ensure strict FDA and international food sanitation codes, the tunnel is integrated with an automated multi-angle Clean-In-Place (CIP) cleaning network for effortless internal washdowns.

Primary Application Fields
Our industrial tunnel freezers are optimized for processing independent, loose, or linear-flow food items:
Aquatic & Seafood Processing: Ideal for individual quick freezing of whole shrimp, peeled prawns, scallops, fish fillets, and sea seafood logistics.
Poultry & Meat Industry: Perfect for handling diced meat, chicken nuggets, pork parts, and small meat patties without structural degradation.
Fruits & Vegetables Export: Highly efficient for sensitive items such as berries, strawberries, diced mangoes, sweet corn kernels, peas, and sliced mushrooms.
Prepared Foods & Bakery: Excellent synchronization with automated lines for frozen dumplings, spring rolls, pastries, and pre-cooked convenience meals.
Turnkey Line Integration & Global Logistics
Guangzhou CBFI provides full end-to-end engineering layouts for your processing floor. The IQF Tunnel Freezer can be seamlessly integrated with automated vibrating feeders, upstream sorting lines, downstream multi-head weighing and vertical bagging systems, and specialized multi-compressor screw/piston refrigeration racks (Bitzer or Hanbell).
All heavy structures are enclosed in sea-freight reinforced wooden crates or secured on heavy industrial steel skids wrapped in multi-layered moisture-proof barrier films. We back our hardware with a global network of senior installation engineers to manage full on-site structural assembly, piping calibration, and operational training.
