Freezing Equipment
Freezing equipment refers to specialized systems designed to rapidly lower food temperatures from ambient levels to very low ranges (typically -18°C to below -40°C) within a short timeframe to preserve structure, color, and nutritional value.
Fluidized Bed IQF Freezer
A complete fluidized bed IQF rapid freezing line includes: chilling (pre-cooling) conveyors, draining conveyors (elevation), vibrating feed shakers (for dewatering and product distribution), and the fluidized bed IQF.
Straight Belt IQF Freezer
The straight belt IQF freezer (flat plate ultra-fast freezing system) is a modern industrial refrigeration technology utilizing a seamless, smooth stainless steel conveyor belt (SUS 304) to rapidly freeze individual quick-frozen products.
Mesh Belt IQF Freezer
The mesh belt IQF freezer is an ultra-fast freezing system utilizing a woven stainless steel mesh conveyor (Inox 304). The open mesh design allows powerful low-temperature cold air blasts from -35°C to -40°C to pass intensely from bottom to top and top to bottom.
Glazing Machine
A glazing machine is specialized industrial equipment installed immediately after the IQF rapid freezing system in seafood and frozen food processing lines. It functions to coat a thin, uniform layer of pure ice water over each product surface to prevent dehydration, oxidation, and freezer burn.
Re-freezer
A re-freezer is a crucial secondary link located right behind the glazing equipment in the seafood cold-processing chain. This device performs a secondary ultra-fast cooling stage to transform the water film just glazed around the food into a completely dry, hard ice shell.
Contact Freezer
A contact freezer (plate freezer) is a specialized industrial refrigeration equipment operating via direct heat transfer by tightly pressing food products between cold metal plates. This is mandatory equipment in seafood processing plants and for freezing formed bakery products.
Blast Freezer
A blast freezer (air blast freezer) is an industrial freezing equipment line utilizing forced convection heat transfer with cold air, deploying high-capacity fans to circulate sub-zero air at high velocity across all food surfaces.
Centrifugal Fans for IQF
Centrifugal fans play a vital role in generating air pressure and directing powerful cold airflow within IQF ultra-fast freezing systems. In IQF technology (especially fluidized bed IQF), the selection and design of centrifugal fans are critical to ensuring completely individual quick freezing of products.
