The SLD Fluidized Bed IQF Freezer applies Individual Quick Freezing Equipment principles refined over years of freezing-technology research. Food enters on a moving mesh belt and passes through a zone of rising airflow velocity. As wind pressure climbs past a set point, the food layer is pushed upward, individual particles separate and suspend above the belt, and the overall bed volume expands - sharply increasing the space between particles. Each suspended piece is wrapped in a continuous stream of low-temperature air and frozen as a standalone unit within a short time frame, which is what allows the finished product to retain its original taste and nutritional content.
Throughout this process, an integrated vibration system on the mesh belt helps surface particles freeze and set quickly while also keeping them mechanically separated during theIndividual Quick Freezing Equipment cycle, preventing pieces from fusing together. The outcome is a freezer capable of producing consistently shaped, independently frozen product suited to automated downstream handling.

Q&A
Q: How long does IQF take?
A: An IQF freezer dramatically reduces freezing time. While conventional methods take hours to freeze meat, an IQF freezing system completes the process in just 90 minutes or less. This rapid speed allows products to bypass the critical ice crystal formation zone (30°F to 25°F), ensuring superior food texture and quality.
Q: What is the difference between IQF and frozen?
A: IQF technology allows each product to freeze individually, preventing clumping. Consequently, an IQF freezer delivers superior product quality and texture compared to traditional bulk cold storage freezing.
Q: How does a fluidized bed freezer prevent product clumping?
A: Upward cold airflow separates and moves products continuously, allowing each piece to freeze individually.
Q: Is the production capacity adjustable?
A: Yes. Belt speed, airflow, freezing time, and product feed rate can be adjusted according to production requirements.
Q: What is the typical operating temperature?
A: Most fluidized bed freezers operate at approximately -30°C to -40°C, depending on the product and required capacity.
Q: What information is required when selecting a freezer?
A: Please provide the product type, dimensions, inlet temperature, required output, target core temperature, and available refrigerant.
Q: What products are suitable for Individual Quick Freezing Equipment?
A: It is ideal for peas, corn, berries, diced vegetables, shrimp, seafood, meat pieces, French fries, and other small products.
