Product Name: Fluidized Bed Quick Freezer

 Fluidized Bed (Fluidization) Quick Freezer | Dedicated to IQF Individual Quick Freezing (Key Equipment for Fruit/Vegetable & Seafood Granule Production Lines)

 I. Working Principle

Low-temperature cold air at -35 to -40°C inside the chamber is sprayed upward from the bottom of the mesh belt at high pressure (air velocity 7-10 m/s). Combined with low-frequency pulse vibration of the belt, granular food materials suspend and boil in a fluidized state, fully enveloped by cold air, ensuring individual pieces do not stick together (IQF). The process features continuous feeding and discharging, enabling automated production line operation.

- Single-stage type: A single mesh belt maintains fluidization throughout; suitable for soft and fragile materials (strawberries, fresh fruit dices).

- Two-stage type (mainstream on the market):

  Stage 1: Rapid surface freezing and hardening, with vibration to break apart and prevent sticking; Stage 2: Deep center freezing, suitable for peas, corn kernels, French fries, and shrimp.

Evaporation temperature: -40°C to -45°C; material inlet temperature: +12 to +15°C; outlet center temperature: ≤ -18°C; freezing time: 10-22 minutes.

 III. Air-Cooled / Water-Cooled Refrigeration Configurations (Integrated with Plant Refrigeration System)

 1. Air-Cooled Integrated Fluidized Bed

The unit's condenser is equipped with a built-in fan for heat dissipation, eliminating the need for cooling towers and circulating water. Simply connect to 380V power and water supply for immediate operation. Suitable for plants with water scarcity or single small production lines. In summer high-temperature environments, capacity may decrease by 8% to 15%. Ideal for small to medium projects.

 2. Water-Cooled Fluidized Bed (Standard for Large Plants)

The condenser water circuit connects to the plant's water-cooled screw chiller unit and shared cooling tower, using the same cooling water as flake ice machines, block ice machines, and water-cooled quick freezers. Condensation temperature remains stable, saving 22% to 30% more electricity compared to air-cooled systems. Capacity remains almost unaffected in midsummer. Standard for quick freezing production lines with a daily output above 5 tons.

 IV. Suitable Frozen Products (Only for Granules/Dices/Strips; Not for Large Pieces)

Fruits & Vegetables: Green peas, corn kernels, edamame, French fries, lotus root dices, carrot granules, garlic sprout segments, shiitake mushrooms, strawberries, raspberries, mango dices, various fresh fruit cuts

Seafood: Individually quick frozen green shrimp, shelled small shellfish, surimi balls, fish dices

Prepared Foods: Quick-frozen rice, macaroni, chicken dices, meat granules, small meatballs

 V. Key Equipment Advantages

1. No Clumping: Fluidized suspension + pulse vibration ensures the final product remains loose and free-flowing, eliminating the need for manual breaking apart, allowing direct packaging after discharge.

2. Low Dehydration Loss: Full cold air wrapping during quick freezing limits moisture loss to ≤2.5%, superior to tunnel plate freezers.

3. All 304 stainless steel construction, with 120mm polyurethane insulation in the chamber, and a mesh belt spray cleaning device at the inlet, meeting food SC and HACCP hygiene standards.

4. Full Variable Frequency Control: Fan and belt speeds are infinitely adjustable, with one-touch speed adjustment for different materials; automatic timed defrosting reduces downtime frequency.

 VI. Complete Plant Refrigeration Solutions (Integrated Selection with Your Existing Equipment)

1. Small Plant Single Line (≤1 ton/hour): Air-cooled fluidized bed + air-cooled screw chiller + air-cooled flake ice machine; no water-cooled infrastructure required.

2. Large Plant Multiple Lines (≥2 tons/hour): Water-cooled fluidized bed + water-cooled screw chiller unit + shared cooling tower + water-cooled block/flake ice machine + water-cooled quick freezer; shared water circulation throughout the plant, resulting in lower overall energy consumption.

 VII. Distinction from Spiral Quick Freezers

- Fluidized Bed: For small granules and bulk IQF products, offering high capacity and fast freezing.

- Spiral Quick Freezer: For whole fish and shrimp, dumplings, pastries, and irregular large coated products.
