Stop the “Cold Edge” Problem in Your Big Ovens
If you’ve run a large-scale bread oven, you know the frustration of the “cold edge.” You pull out a tray and the center looks perfect, but the edges are pale. It’s annoying. It happens because heat just naturally leaks out of the sides of the chamber faster than it does in the middle. Most standard heaters just can’t keep up with that loss, and you end up with inconsistent loaves. Here is how we fix it. We use high-purity quartz tubes. Now, instead of just heating up the air and hoping for the best, these lamps use infrared radiation. Think of it like the sun hitting your skin on a clear day—the energy goes straight into the dough. It’s fast. Really fast. You don’t have to wait around for the air to warm up; the heat hits the target almost instantly. To really kill those cold spots, we use tubes with high watt density. By packing a lot of power into a small quartz envelope, we create a “hot zone” right where the oven walls are stealing the heat. It balances everything out. And since these are halogen-filled, they last longer. The halogen cycle basically “recycles” the tungsten filament as it evaporates, so the tubes don’t burn out the moment you put them under a heavy load. Getting them installed is the easy part. These are designed to be drop-in replacements. They slide right into your existing brackets without needing a total overhaul of your setup. But, there is one thing to watch out for. Because these tubes get incredibly hot on the surface, you have to make sure your oven’s outer insulation is solid. If you crank up the wattage to fight severe heat loss, the outside of your oven chassis might get warmer than usual. It’s a small trade-off for finally getting that perfect, edge-to-edge golden brown on every single loaf.
