Have you ever wondered what it takes to build a 20-ton direct cooling block ice machine? In our latest factory video, we open the doors of the ICESTA workshop and walk through every major manufacturing step. From precision aluminum welding to final system testing, this article explains how a large-capacity block ice machine is produced—and what to look for when choosing an ice block maker machine for your business.
Whether you need an ice machine 10 ton capacity for a growing ice business or a fully automatic 20-ton unit for industrial use, manufacturing quality directly affects ice output, energy consumption, and long-term reliability.
A direct cooling block ice machine freezes water by bringing refrigerant into direct contact with aluminum evaporator plates attached to ice molds. This design transfers heat more efficiently than traditional brine systems, reduces moving parts, and helps produce solid block ice with lower energy consumption. ICESTA focuses on direct cooling technology because it offers consistent ice quality and simpler maintenance.
The evaporator is the heart of any block ice machine. At ICESTA, we use precise aluminum welding with strict standards. Every seam must remain sealed, smooth, and tight. This is not just about appearance—it directly determines cooling performance, ice quality, and system lifespan. A poorly welded evaporator can leak refrigerant, reduce freezing speed, and cause uneven ice formation. Our welding process ensures each evaporator meets pressure and leak-test requirements before moving to the next stage.
After welding, the evaporator is fitted with heavy-duty frames, slide rails, and cooling pipes. This step builds the complete ice-making unit. The frame supports the evaporator and ice molds during lifting and harvesting, so structural strength is critical. ICESTA designs frames for stable operation, even in continuous 24-hour production environments.
Modern ice plants need more than mechanical reliability—they need intelligent control. ICESTA equips the 20-ton block ice machine with a Siemens PLC and Schneider electrical components. All wiring, installation, and debugging are completed in our workshop. The system supports remote monitoring on your phone, so you can check running status, temperature, and alarms from anywhere. This reduces onsite labor and allows faster response to potential issues.
A block ice machine is only as reliable as its compressor. ICESTA uses Bitzer compressors for this 20-ton unit, delivering steady and efficient refrigeration. After assembly, we run full system tests to verify cooling performance, electrical safety, and automatic control. The machine is operated under controlled conditions before it is approved for packaging.
Each production procedure receives separate strict inspection before final assembly. Our quality team checks welding, assembly, wiring, and system performance. Only after passing all inspections is the 20-ton block ice machine considered ready to ship. This process reduces field failures and protects your investment.
Choosing the right capacity is one of the most important decisions for an ice plant. ICESTA offers multiple capacities, including a popular ice machine 10 ton model and the larger 20-ton automatic block ice machine shown in the video.
ICESTA is ready to support your project with both ice machine 10 ton and 20-ton block ice machine options. Our team can help you choose the right configuration, plan installation, and provide after-sales support.
