40-Ton Direct Cooling Block Ice Machine

40-Ton Direct Cooling Block Ice Machine Description

A 40-ton direct cooling block ice machine is an industrial ice-making system capable of producing 40 metric tons (40,000 kg) of block ice per 24 hours using a direct expansion (DX) refrigeration system. Below are the key specifications, features, and considerations for this machine:

Key Specifications of a 40-Ton Direct Cooling Block Ice Machine

1. Production Capacity

   • 40 tons per day (based on 24-hour operation).

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

   • Freezing time: ~10–24 hours (varies with block size and water temperature).

2. Refrigeration System

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

   • Refrigerant Options:

     • Common refrigerants: R404A, R507, NH3 (ammonia), or CO₂.

     • Eco-friendly choices: CO₂ (R744) or NH3 (for large-scale systems).

   • Energy Efficiency: More efficient than brine systems (no brine pump needed).

3. Key Components

   • Compressor: Semi-hermetic or screw compressor (depends on cooling demand).

   • Condenser:

     • Air-cooled (for water-scarce areas).

     • Water-cooled (higher efficiency, needs cooling tower).

     • Evaporative condenser (balanced efficiency & water use).

   • Ice Molds: Stainless steel or galvanized steel (anti-corrosion).

   • Control System: PLC-based automation for temperature & ice harvesting.

4. Power Requirements

   • Estimated power consumption: 60–90 kW (depends on efficiency & ambient conditions).

   • Voltage: Typically 380V/50Hz (3-phase) (can be customized).

5. Water Consumption

   • Water needed: ~1.1–1.2 times ice weight (due to freezing expansion).

   • Water quality: Filtered or softened to prevent scaling.

6. Dimensions & Space Requirements

   • Machine footprint: ~20–30 m² (varies with layout).

   • Height: ~3–4 meters (with lifting device for ice blocks).

7. Ice Harvesting & Storage

   • Automatic de-icing: Uses hot gas or warm water to release blocks.

   • Storage: Requires an insulated ice store or cold room.

Advantages of Direct Cooling Block Ice Machines

✅ Higher energy efficiency (no brine circulation losses).
✅ Faster freezing than brine systems.
✅ Lower maintenance (no brine corrosion or pump issues).
✅ Compact design (saves space).
