Getting That Perfect Golden Crust: A Guide to IR Intensity

Getting a bakery-grade crust on industrial bread isn’t just about cranking up the heat. If you want that deep, golden-brown look without drying out the inside of the loaf, you need the right kind of infrared (IR) energy. In a steam oven, we use specialized IR curing lamps to kickstart the Maillard reaction. That’s just the fancy way of saying we’re triggering the chemistry that makes bread look and taste delicious. Finding the Sweet Spot Here is the thing: you can’t just throw more wattage at the problem to get a darker crust. If you do, you’ll burn the sugars on the surface before the heat even gets deep enough. You end up with a charred skin and a center that’s still raw. We usually start with medium-wave IR emitters for artisanal loaves. It’s the best way to get that surface sear while still making sure the heat penetrates the dough. The Gear Since steam ovens are humid and high-pressure, we build our lamps with high-purity quartz tubes. They’re tough. They handle the environment without cracking. We also customize the length to fit your specific oven. But the real trick is the distance. If the lamp is sitting right on top of the bread, we dial back the wattage so you don’t get burnt hot spots. If it’s tucked further away, we bump up the power density so the energy actually reaches the dough. The Trade-off: Speed vs. Wear and Tear High-intensity lamps are great for fast browning, which means you can push more bread through the line. But there’s a catch. When you run a lamp at its absolute limit, the filament evaporates faster. You get your color quickly, but you’ll be swapping out tubes a lot more often. My advice? Balance your IR intensity with your conveyor speed. It keeps the quartz envelopes lasting longer. Also, wire everything into a PID controller. It lets you modulate the power so you don’t accidentally overshoot your target temperature and ruin a batch.
