The SLD Fluidized Bed IQF Freezer is the product of years of dedicated R&D in Fluidized Bed Freezing technology, combining domestic and international fluidization principles into a next-generation system. As product moves along the mesh belt, increasing airflow velocity lifts the frozen surface layer; once air pressure exceeds a threshold, individual particles are lofted and suspended, expanding the bed and sharply increasing void fraction within the product mass. Each suspended particle is enveloped in low-temperature airflow and frozen independently within seconds, locking in flavor and nutritional value before structural breakdown can occur.
A vibration mechanism integrated into the mesh belt assists surface crystallization while mechanically separating particles, preventing clumping throughout the Fluidized Bed Freezing cycle. This ensures every unit freezes as a discrete, free-flowing piece - a property critical for downstream packaging, storage density, and metering accuracy.

Q&A
Q: What is the difference between IQF and non IQF?
A: Compared to traditional methods, the IQF freezer stands out as the superior choice for high-quality food preservation. While block freezing often damages cellular structures through large ice crystals and freezer burn, our IQF freezing technology locks in texture and nutrients through rapid temperature reduction.
Q: What are the benefits of IQF freezer?
A:
Why an IQF Freezer is Superior for Food Preservation: One of the primary benefits of using an IQF freezer is the rapid processing speed-completing in just minutes. This ultra-fast freezing prevents the formation of large ice crystals that can destroy cell membranes at a molecular level.
By utilizing advanced IQF technology, food products maintain their original shape, color, aroma, and taste far better than traditional methods. Unlike block freezing, an IQF freezing system keeps individual pieces separate. This not only ensures a premium product but also promotes food sustainability by allowing consumers to defrost only the exact portion needed, significantly reducing food waste.
Q: What products are suitable for fluidized IQF freezing?
A: It is ideal for peas, corn, berries, diced vegetables, shrimp, seafood, meat pieces, French fries, and other small products.
