Why the Best Bakers are Adding Infrared to Their Ovens
Most convection ovens just blow hot air around. But here’s the problem: air is actually pretty bad at moving heat. If you’ve ever pulled a tray out only to find some loaves are perfect while others have raw centers or pale crusts, you know exactly what I mean. It’s frustrating, especially when you’re pushing out high volumes. That’s where infrared (IR) heating comes in. Instead of waiting for the air to warm up the bread, IR lamps beam energy straight into the dough. It’s direct. It’s fast. And it changes the whole result.
The Secret to That Perfect Crust
We use quartz halogen tubes for this because they don’t mess around. They hit the right temperature almost instantly. While a standard oven takes forever to heat up the entire cavity, these lamps send out shortwave radiation that sinks right into the outer layer of the dough. This kicks the Maillard reaction into high gear. The result? That deep, mahogany-colored crust we all love, but without drying out the inside of the bread. You get the crunch and the softness in one go.
Getting the Hardware Right
Depending on your oven’s power setup, you’ll usually see these lamps running at 230V or 400V. We stick with R7s or SK15 connectors. Why? Because they fit tight. The last thing you want is a connection rattling loose because the oven is expanding and contracting from the heat. The quartz envelope is the real hero here. It lets the filament get incredibly hot while keeping everything stable inside. One quick tip if you’re installing these in a tight space:**watch your clearances.**These tubes pack a massive amount of heat into a tiny area. If you don’t use housing materials that can take the heat, you’re going to end up warping your oven chassis. And that’s a headache nobody wants.
The Catch (And How to Fix It)
Now, IR heating is powerful, but it can be a bit aggressive. If your controller isn’t dialed in, you’ll end up with burnt tops and a raw center. It happens. To stop that, we recommend pairing the lamps with a PWM (Pulse Width Modulation) controller. Basically, it flickers the lamps on and off so fast you can’t see it, which keeps the surface temperature steady. It takes a bit more effort to get the logic right, but for that perfect crust? It’s worth every second.
