Key Advantages of Direct Cooling Block Ice Machines
Energy Efficiency: Direct cooling systems utilize refrigerant and water directly, eliminating the need for brine and reducing energy consumption by up to 20% compared to brine ice systems. This translates to lower operational costs and a smaller carbon footprint.
Material Durability: Direct cooling machines typically use durable aluminum evaporators, which are resistant to corrosion and offer a longer lifespan compared to the galvanized steel or carbon steel used in brine ice systems.
Ice Quality: Direct cooling machines produce ice blocks that meet edible standards, making them suitable for applications where hygiene is crucial. Salt water ice machine, on the other hand, often produce ice with poor hygiene due to the presence of saltwater.
Automation and Space Utilization: Direct cooling machines are fully automated, streamlining the process of deicing, moving, and storing ice blocks. This results in higher productivity and reduced labor costs. Additionally, they occupy less space, saving on civil construction costs.
Minimal Infrastructure Requirements: Direct cooling systems only require access to water and electricity, eliminating the need for extensive infrastructure and reducing upfront investment.
Integrated design for easy transportation, installation, and relocation.
Aluminium alloy ice molds for enhanced rust resistance and extended lifespan.
Automated ice deicing and pushing reduces labor costs.
Direct cooling design reduces heat loss by over 20%.
Ice Hardness and Melting Resistance
Contrary to popular belief, the hardness and melting resistance of ice blocks produced by direct cooling and brine systems are comparable. While the temperature of the refrigerant in direct cooling systems is slightly lower, resulting in slightly harder ice, this difference is negligible in practical applications. Both types of ice blocks have similar melting rates and can be used effectively for various cooling and preservation purposes.
Conclusion
The advantages of direct cooling block ice machines over brine systems are clear. Their energy efficiency, durability, ease of operation, and lower operational costs make them the preferred choice for businesses seeking a reliable and cost-effective ice-making solution. As the demand for high-quality ice continues to grow, direct cooling technology is poised to revolutionize the ice-making industry.
