Fixing the “Cold Spot” Problem in Multi-Deck Bread Ovens
If you’ve ever used a multi-deck oven, you know the struggle. You pull out the top tray and it’s perfect. The bottom one? Great. But the middle deck? It’s lagging. It’s a common headache when you’re relying on one heat source to do all the heavy lifting. We figured out a better way. Instead of hoping the heat travels, we put independent infrared heating tubes in every single deck. This means you get to decide exactly how much heat goes into each layer.
Why IR Radiation Actually Works
Most ovens just move hot air around. That’s slow, and the second you open the door, all that warmth vanishes into the kitchen. We use short-wave infrared lamps. Instead of heating the air, they beam energy straight into the dough. We’ve wired these into their own control loops, so you can keep the temperature steady across the board. Here’s the best part: if your bottom deck is losing heat through the floor, you don’t have to turn up the heat for the whole oven and risk burning the top crusts. You just crank the power to that one specific element. Simple.
The Nitty-Gritty on the Hardware
These tubes are basically tungsten filaments wrapped in quartz. Depending on your power grid, we can tweak the wattage and voltage to fit your shop. If you need to sear a crust or get a quick reheat, go for the high-wattage tubes—they ramp up fast. Just a heads-up: make sure your wiring and contactors can handle the current. If they can’t, you’re just asking for a burnout.
A Few Things to Watch Out For
Now, there’s a trade-off. Adding more tubes means more parts. More parts mean more things that could eventually break and a slightly messier wiring harness to deal with. You also have to be careful with the reflectors. If they’re crooked, you’re wasting energy and you might actually warp your oven chassis. Space them out properly. And when you’re swapping in replacement tubes, double-check the length and the connectors. If a tube is even a tiny bit too long, it puts pressure on the quartz seal. Once it heats up and expands, it’ll pop. Not a great way to start a morning bake.
