Ice Type Produced
The Hoshizaki KM-901MRJZ produces crescent cubes, a hallmark of Hoshizaki ice machines. The unique, curved structure, measuring 1/2 in x 1.5 in x 1.125 in (1.27 cm x 3.81 cm x 2.857 cm), provides several benefits. The curved surface allows water to flow evenly during freezing, washing away impurities and ensuring the ice remains crystal clear. These cubes are tough and melt slower than standard ice, minimizing drink dilution. Additionally, the crescent design is visually more appealing, making them perfect for beverages in bars, restaurants, and catered events, as they melt slowly and minimize drink dilution.
