Learn MoreIQF Fluidized Bed Freezer
The IQF Fluidized Bed Freezer is a high-efficiency individual quick freezing system designed for granular, sliced, or small-sized food products. By using high-velocity airflow to suspend and separate products on the conveyor belt, it ensures non-sticking, uniform freezing and is widely used in meat, seafood, fruits, vegetables, and pet food processing industries.
Overview
The fluidized bed freezer utilizes advanced aerodynamic design to keep food products semi-suspended or gently bouncing during freezing, effectively preventing sticking. Compared with traditional freezing methods, it significantly improves freezing speed and final product appearance.
LONKIA IQF fluidized bed freezers support continuous processing of various food products, featuring robust structure and stable operation, making them ideal for medium to large food processing plants and automated production lines.
Working Principle
After entering the freezing zone via the conveyor belt, strong and evenly distributed cold air is blown upward from below, creating a fluidized effect. The cold air rapidly removes heat from the food, achieving fast freezing.
This process ensures each food piece is individually quick frozen (IQF), without clumping or damage, maintaining its original shape and quality.
How Fluidized Bed Freezing Works
After pre-treatment (washing, cutting, grading), the food is evenly spread on the conveyor belt and rapidly cooled to the target temperature under high-velocity airflow.
Once frozen, the products remain as free-flowing individual pieces, ready for packaging or further processing.
