10-Ton Direct Cooling Block Ice Machine

10-Ton Direct Cooling Block Ice Machine Description

A 10-ton direct cooling block ice machine is an industrial ice-making system designed to produce 10 tons (10,000 kg) of block ice per day using the direct cooling (direct refrigeration) method. Here’s a detailed breakdown of its features, working principle, and applications:

Key Features:

1. Production Capacity:

   • Produces 10 tons of block ice in 24 hours (each block typically weighs 25 kg, 50 kg, or 100 kg depending on mold size).

   • Ice thickness: Usually 10–25 cm (customizable).

2. Direct Cooling System:

   • Uses direct expansion refrigeration (evaporator coils are in direct contact with the brine water), making it more energy-efficient than indirect cooling systems.

   • No secondary coolant required (unlike indirect systems that use brine circulation).

3. Refrigeration Components:

   • Compressor: High-efficiency screw or piston compressor (e.g., Bitzer, Hanbell, or Refcomp).

   • Condenser: Air-cooled, water-cooled, or evaporative type.

   • Evaporator: Stainless steel or corrosion-resistant coated tubes submerged in brine tank.

4. Ice Molds:

   • Made of galvanized steel, stainless steel, or PE plastic for durability.

   • Standard block sizes: 25 kg, 50 kg, or 100 kg.

5. Automation & Control:

   • PLC control system for automatic operation (filling, freezing, harvesting).

   • Temperature and pressure monitoring for safety.

6. Energy Efficiency:

   • ~60–80 kWh per ton of ice (varies based on ambient temperature and water quality).

   • Can use eco-friendly refrigerants (R404A, R507, or ammonia/NH3 for larger systems).

7. Installation Requirements:

   • Power Supply: 380V/50Hz (3-phase) or customized for local voltage.

   • Water Supply: Clean freshwater (TDS < 200 ppm for clear ice).

   • Space Needed: ~20–30 m² (including ice storage area).

Working Principle:

1. Water Filling: Freshwater is poured into the ice molds.

2. Freezing Process: The evaporator cools the brine solution (usually calcium chloride) to -10°C to -15°C, freezing the water gradually from the outside in.

3. Harvesting: After freezing (typically 10–24 hours, depending on block size), the blocks are released by slightly warming the molds (using hot gas or water).

4. Storage/Transport: Blocks are moved to an ice storage room or transported for use.

Applications:

✔ Fishing & Seafood Processing (long-lasting ice for preserving catch).
✔ Concrete Cooling (construction industry).
✔ Food Processing & Cold Storage.
✔ Chemical & Pharmaceutical Industries.
✔ Supermarkets & Slaughterhouses.

Advantages Over Flake/Ice Tube Machines:

• Longer melting time (ideal for cooling over extended periods).

• Higher density (less wasted meltwater).

• Easier to handle & transport (uniform block shapes).
