Block Ice Machine — Industrial & Ice Factory Solutions
Large, solid ice blocks with the slowest melting rate of any ice type — built for fishery cold chains, ice wholesale businesses, long-distance transportation, and industrial cooling. Our block ice machines range from 1 to 50 tons per day, available in direct cooling and brine tank systems.
What is Block Ice and Why Is It Essential for Cold Chain?
Block ice is the oldest and most economical form of manufactured ice. Large rectangular blocks — typically weighing 5kg, 10kg, 25kg, 50kg, or even 100kg each — are produced by freezing water in molds over an extended period. The result is an extremely dense, solid ice block with the slowest melting rate of any ice type, making it the standard choice when long-lasting cooling is the priority.
Block ice remains indispensable in the global cold chain, particularly in developing markets where cold storage infrastructure is limited. Fishing communities across Southeast Asia and Africa rely on block ice to preserve catch during transport from the ocean to processing plants and markets. Ice factories in the Philippines, Indonesia, Nigeria, and Vietnam produce block ice as their primary product for wholesale distribution. Its low production cost per ton and extreme durability make it the most cost-effective cooling solution for large-scale operations.
Key Advantages

✅ Lowest cost per ton — most economical ice to produce at scale
✅ Ideal for transport — maintains cold chain over long distances without electricity
✅ No power needed after production — blocks keep products cold passively
✅ Versatile block sizes — from 5kg retail blocks to 100kg industrial blocks
Block Ice Machine Models — Choose Your Capacity
Available in two technologies: Direct Cooling (faster, more energy efficient, fully automatic) and Brine Tank (traditional, lower upfront cost, suitable for large-scale operations). All models produce food-grade ice blocks.

Where is Block Ice Used?
1: Fishery & Seafood Cold Chain
Block ice is the foundation of seafood cold chain logistics worldwide. Fishing boats carry block ice to preserve the catch at sea. Fish markets and processing plants use crushed block ice to maintain freshness. In regions without reliable cold storage, block ice is the only practical method to keep seafood safe from the ocean to the consumer’s table.
2: Ice Factory & Wholesale
Block ice factories are one of the most common and profitable ice businesses in tropical markets. Ice factories produce block ice in large quantities and sell to restaurants, wet markets, fish vendors, construction sites, and households through a distribution network. The high demand and low competition in many developing markets make block ice production an attractive business opportunity.
3: Long-Distance Transportation
When goods need to travel long distances without refrigeration — fish from coastal areas to inland cities, agricultural produce from farms to markets, or temperature-sensitive materials between provinces — block ice is the solution. Its extremely slow melting rate provides hours of passive cooling in insulated containers, trucks, and cargo holds.
4: Ice Sculpture & Events
Artists and event organizers use block ice for ice sculptures at weddings, festivals, corporate events, and exhibitions. Clear, dense blocks provide the ideal raw material for carving. Specialized block ice machines can produce crystal-clear blocks specifically for artistic and display purposes.
Frequently Asked Questions About Block Ice Machines
What is the difference between direct cooling and brine tank block ice machines?
Direct cooling block ice machines freeze water directly in aluminum molds using refrigerant channels built into the mold walls. They are faster (freezing in 4-8 hours vs 18-24 hours for brine), more energy efficient (30-40% less power per ton), fully automatic (no crane needed for de-icing), and produce cleaner, food-grade ice. Brine tank block ice machines submerge ice molds into a tank of salt brine that acts as the cooling medium. They have a lower upfront cost and are a proven traditional technology, but require more space, more la
What block ice sizes can your machines produce?
Our block ice machines produce blocks in standard sizes: 5kg, 10kg, 12.5kg, 25kg, 50kg, and 100kg. The block size is determined by the mold dimensions, which are selected at the time of order. Most ice factories producing for retail and wholesale choose 25kg or 50kg blocks. Smaller 5-10kg blocks are popular for direct consumer sale. Larger 100kg blocks are used for fishery cold chain and industrial applications. Custom mold sizes are also available.
How much electricity does it cost to produce one ton of block ice?
With direct cooling technology, producing one ton of block ice consumes approximately 65-85 kWh of electricity, depending on ambient temperature and water inlet temperature. Brine tank systems consume approximately 100-120 kWh per ton. To calculate your daily operating cost, multiply by your local electricity rate. For example, at $0.10 per kWh with a 10-ton direct cooling machine, daily electricity cost is approximately $65-85. We provide detailed energy consumption data for each model.
Can a block ice machine run with unreliable power supply?
Block ice machines require continuous power during the freezing cycle. Power interruptions can result in incomplete blocks and wasted water. For areas with unstable grid power, we recommend pairing the machine with a backup diesel generator. For brine tank systems, the thermal mass of the brine tank provides some buffer — short interruptions of 30-60 minutes may be tolerable. We advise all customers in regions with unreliable power to budget for a generator as part of the complete block ice plant setup.
How long does it take to install a block ice machine and start production?
A direct cooling block ice machine typically takes 3-7 days for installation and commissioning, depending on the capacity. Foundation preparation, electrical connections, water supply, and cooling tower setup need to be completed before machine installation. We provide complete installation documentation including foundation drawings, electrical diagrams, and plumbing layouts. On-site installation supervision is available for large projects.
