Fluidized Bed IQF Freezer Manufacturer for Vegetables, Fruits and Small Food Products
KELONG provides SLD Series Fluidized Bed IQF Freezer solutions for processors who need fast individual freezing, stable product quality, and continuous production efficiency. This type of freezer is especially suitable for small-piece and loose products such as diced vegetables, sliced vegetables, peas, corn kernels, berries, fruits, small seafood, prepared food pieces, and other products that need to remain separate after freezing.
A fluidized bed freezer uses powerful low-temperature airflow to lift and separate materials on the mesh belt, creating a fluidized freezing effect. This helps prevent sticking, clumping, and surface deformation while improving freezing speed and product appearance. KELONG can also provide matching pre-processing equipment before the freezer, including bubble washer, chain blancher, normal-temperature cooler, ice-water pre-cooler, vibration dewatering machine, elevator, and vibrating distributor.
Complete Fruit and Vegetable IQF Freezing Line with Fluidized Bed Freezer
A stable fluidized IQF freezing result depends not only on the freezer itself, but also on proper pre-treatment before freezing. For fruit and vegetable products, a typical line may include bubble washing, blanching, normal-temperature cooling, ice-water pre-cooling, vibration dewatering, elevator conveying, vibrating distribution, and SLD fluidized bed IQF freezing.
The bubble washer removes mud and impurities; the chain blancher helps protect color and reduce enzyme activity; the normal-temperature cooler and ice-water pre-cooler lower product temperature before freezing; the vibration dewatering machine reduces surface water; the elevator and vibrating distributor help feed materials evenly into the freezer. By combining these machines correctly, the whole line can achieve better freezing quality, lower freezer load, and more stable output.

How Fluidized Bed IQF Freezing Works
The fluidized bed IQF freezer blows strong cold air upward through the mesh belt and product layer. When the airflow speed and product feeding thickness are properly matched, small pieces are lifted slightly and separated from each other, similar to a fluidized state. This allows cold air to contact more product surface and freeze each piece quickly and individually.
Main advantages include:
• Fast individual freezing for small and loose products
• Reduced sticking, clumping, and product deformation
• Uniform airflow distribution for consistent freezing quality
• Adjustable belt speed and airflow for different product types
• Suitable for sliced, diced, granular, and small-piece food materials
• Continuous production with stable capacity
• Hygienic stainless-steel structure for food processing environments
• Easy connection with washing, blanching, cooling, dewatering, and conveying equipment
