When you grab a handful of cylindrical ice tubes from a bag or watch them tumble into your drink at a restaurant, you might not think about the engineering marvel behind them. Tube ice—those hollow, uniform cylinders—is a staple in industries from hospitality to packaged ice production, and machines like Vogt’s tube ice makers have been perfecting the process since the 1930s. But how exactly do these commercial powerhouses turn water into those sleek, hollow tubes? Let’s break down the fascinating mechanics of tube ice makers and explore why they’ve become an industry standard. The Basics of Tube Ice Tube ice is distinct for its shape: a cylinder with a hollow core, typically 1–2 inches long and varying in diameter (often 7/8" to 1-1/2"). This design offers a high surface area for rapid cooling, making it ideal for beverages, food preservation, and industrial uses like concrete cooling. Unlike cube or flake ice, tube ice is produced in a specialized process that Vogt pioneere...
