Getting Your Bread Crust Just Right
If you’ve ever struggled with getting that perfect, golden-brown sear on your bread without overheating the entire oven, you know the frustration. That’s why we use halogen infrared lamps. Instead of waiting for the air in the oven to heat up—which takes forever—these lamps shoot shortwave radiation straight into the dough. It’s fast. Really fast. You can trigger a crust sear or that final browning phase in a matter of seconds. The secret is in the control. You can’t just plug these in and hope for the best. To get them talking to your PLC or PID controller, you have to match the lamp’s wattage and voltage to how fast your power supply can switch. We usually stick with SCR power controllers to handle the voltage. Why? Because it stops the lamps from burning out when they’re cycling rapidly. If you try to run a high-wattage tube on a cheap controller, you’re going to see flickering. And flickering means your bread comes out with uneven heat spots. Nobody wants that. A bit about the gear These lamps are built with a quartz envelope and filled with halogen gas. The gas actually pushes the tungsten from the filament back to the center, which keeps the lamp alive much longer. We can do custom lengths and connectors, too. It sounds like a small detail, but a tight fit is everything. If the lamp is loose in the heating array, you’re just leaking heat and wasting money. Where things can go wrong Here’s the thing: these lamps pack a massive punch of heat. That speed is great, but it means your sensor placement has to be spot on. If your thermocouple is sitting too far away from the bread, the control loop lags. By the time the sensor realizes it’s hot enough, you’ve already overshot the target and burned your product. It’s a delicate balance between how close the lamp is to the bread and how you tune your PID. One last tip: give these lamps their own dedicated circuit. High-wattage arrays pull a lot of current. If you have a voltage drop in your wiring, you’ll end up with some zones browning perfectly and others looking pale. Keep the power steady, and the bread will follow.
