The LJ IQF Fluidized Bed Quick Freezer is the premier solution for individual quick freezing of granular, sliced, and diced food items. By utilizing high-velocity low-temperature airflow, the machine creates a "fluidized" or "boiling" state for the products, ensuring each piece is frozen rapidly and independently. This technology eliminates clumping, preserves cellular structure, and maintains the natural flavor and nutritional value of fresh produce, making it ideal for high-end frozen food export.
Core Advantages & Features
True IQF Technology: High-speed vertical airflow ensures the material stays in a suspended state, preventing adhesion and ensuring 100% individual freezing.
Superior Food Quality: Rapid heat exchange minimizes ice crystal formation, preserving the texture, color, and nutrients of delicate items like berries and peas.
Hygiene & Food Safety: Fully enclosed SUS304 stainless steel structure with an openable design for easy internal cleaning and disinfection, compliant with FDA and CE standards.
Energy Efficiency: Optimized air duct design and high-performance insulation panels significantly reduce cold loss and energy consumption.
Gentle Handling: The fluidized bed design minimizes mechanical damage to soft products, ensuring high yield and premium appearance.

Operation & Maintenance Guide
SOP: Start the refrigeration system first, once the tunnel temperature reaches -30°C, start the conveyor and feeding system.
Cleaning: The machine features an internal cleaning system. Ensure the belt and heat exchanger are rinsed after each production cycle to prevent frost buildup.
Daily Check: Inspect the defrosting system and ensures the fan motors are running smoothly to maintain optimal airflow.
2. Q: What’s the difference between a normal tunnel freezer and an IQF fluidized bed? A: A fluidized bed uses vertical airflow to keep products suspended, which is essential for small items like peas to prevent them from freezing into a block.
3. Q: What is your after-sales service? A: We support one year warranty, free after-sales for life, and engineers respond to feedback 48 hours.
4. Q: Can the freezing speed be adjusted? A: Yes, the conveyor speed and fan intensity are fully adjustable via the PLC touch screen to match the freezing requirements of different materials.
