CBFI 1.5 Tons/Hour Fluidized Bed IQF Freezer

1. Industry Background: Rising Demand for High-Quality Freezing

The global pearl milk tea market continues to grow at double-digit rates, driven by large-scale consumption across Asia-Pacific and emerging international markets.

However, traditional freezing methods present structural limitations:

Surface cracking due to uneven freezing

Product adhesion and clumping during batch processing

Manual sorting requirements increasing labor cost

Ice crystal damage affecting texture elasticity ("Q-bounce" quality loss)

These issues directly impact product consistency and commercial scalability.

2. Technical Solution: Fluidized Bed IQF Freezing System

CBFI fluidized bed freezing technology uses controlled airflow suspension to achieve uniform three-dimensional freezing of individual particles.

Core Principle

Products are suspended in a high-velocity cold air stream, enabling full surface exposure to cold airflow and preventing contact-based adhesion.

3. Key Engineering Advantages

1. Fluidized Suspension Freezing

Bottom air distribution system creates controlled particle suspension

Air velocity: 2–4 m/s

Ensures 360° uniform cooling of each particle

Eliminates clumping and stacking during freezing

2. High-Efficiency Rapid Freezing

Operating temperature: -35°C to -40°C

Freezing time: ≤ 12 minutes

Ice crystal size controlled below 20 μm

Preserves texture elasticity and structural integrity

3. Intelligent Temperature Control System

Multi-zone freezing design:

Pre-cooling zone

Rapid freezing zone

Stabilization zone

Temperature accuracy: ±0.5°C

Prevents thermal shock and moisture expansion damage

4. Modular Expansion Design

Supports multi-line expansion configuration

Scalable capacity for peak season demand

Flexible integration into existing production systems

4. Performance Comparison (Traditional vs IQF System)

5. Application Case: Pearl Processing Industry Upgrade

A Southeast Asian pearl manufacturer (annual capacity ~5000 tons) faced:

Key Challenges

Low capacity (0.8 tons/hour per line)

High adhesion rate (>15%) requiring manual sorting

Temperature instability causing product returns (~3%)

After CBFI IQF Upgrade (1.5 T/H System)

Capacity increased to 1.5 tons/hour per line

Adhesion rate reduced to <1%

Labor sorting reduced by 80%

Customer complaint rate reduced from 3% → 0.2%

6. Engineering Mechanism Behind Performance

1. Aerodynamic Suspension Design

CFD-optimized air distribution plate (2–3 mm aperture design)

Stable particle suspension ensures uniform freezing exposure

Eliminates product stacking and freezing inconsistency

2. High-Efficiency Heat Transfer System

Low-temperature refrigerant (e.g., R404A) atomization

Enhanced heat exchange coefficient (2–3× conventional air freezing)

3. Controlled Ice Crystal Formation

Prevents rapid freezing shock

Maintains product microstructure integrity

Ensures stable chewable texture after thawing

7. Industrial and Commercial Value

Production Efficiency

40% reduction in order delivery cycle during peak season

Continuous high-capacity production stability

Cost Optimization

Annual labor cost reduction: significant due to automation

Energy cost reduction: ~33% per kg of product

Market Competitiveness

Enables entry into premium beverage supply chains

Improves product grade and pricing power (5–8% margin increase)

8. Sustainability Impact

CO₂ emissions reduced by ~23 tons annually

Complies with EU ESG sustainability requirements

30% reduction in floor space compared to conventional systems

Lower resource consumption per unit output
