30-Ton Direct Cooling Block Ice Machine

30-Ton Direct Cooling Block Ice Machine – Key Specifications

1. Production Capacity

   • 30 metric tons (30,000 kg) per 24 hours (standard conditions).

   • Block Sizes: Typically 12.5 kg, 25 kg, or 50 kg (customizable).

   • Freezing Time: ~10–20 hours (depends on block size, water temp, and ambient conditions).

2. Refrigeration System

   • Direct Expansion (DX) Cooling: Evaporator directly chills ice molds (no secondary coolant like brine).

   • Refrigerant Options:

     • Common: R404A, R507 (Freon).

     • Eco-Friendly: NH3 (Ammonia) or CO₂ (for large-scale, high-efficiency systems).

   • Energy Efficiency: ~15–20% more efficient than brine systems (no brine pump losses).

3. Core Components

   • Compressor: Semi-hermetic or screw type (e.g., Bitzer, Hanbell) – ~45–70 kW power draw.

   • Condenser:

     • Air-cooled: Low water use, easier installation.

     • Water-cooled: Higher efficiency (requires cooling tower).

   • Ice Molds: Stainless steel or galvanized steel (anti-rust, durable).

   • Control System: Fully automated PLC with touchscreen (monitors freezing, harvesting, alarms).

4. Power & Utility Requirements

   • Power Consumption: ~50–75 kW (depends on compressor type and ambient temp).

   • Voltage: Standard 380V/50Hz/3-phase (customizable to 440V/60Hz).

   • Water Use: ~33–36 m³/day (1.1–1.2x ice weight due to expansion).

5. Footprint & Installation

   • Machine Dimensions: ~15–25 m² floor space (+ storage area for ice).

   • Height: ~3–4 meters (with lifting hoist for block handling).

Advantages vs. Brine Systems

✔ Faster Freezing: Direct cooling reduces ice formation time.
✔ Lower Operating Costs: No brine pumps or corrosion maintenance.
✔ Compact Design: Saves space vs. brine tanks.
