How to actually speed up your baking line
Most convection ovens just push hot air around. It works, but it’s slow. If you’re trying to get more product out the door every minute, relying on air alone is going to hold you back. The secret is adding radiant heat. Specifically, far infrared (FIR) heating tubes. Instead of waiting for the air to warm the food, these tubes hit the surface of the product directly. It gets the core temperature up way faster. The trick to better throughput In a fast-moving line, the real headache is the “dwell time”—that window where the food just has to sit there until the middle is cooked. We like FIR tubes because they use longer wavelengths. They actually sink deeper into the food than the shortwave stuff does. When you tuck these into the ceiling or the side-walls of your tunnel, you get the best of both worlds. The convection keeps the air steady, while the FIR tubes give the product a heavy hit of heat. This means you can crank up the belt speed without worrying about serving something raw in the middle. Picking the right gear (and the risks) We usually pick the tubes based on how much space you have and how much power your facility can handle. High-wattage quartz tubes are great because they heat up almost instantly. But you have to be careful. If you cram too many kilowatts into one small spot, you’ll torch the outside of your food before the center even notices it’s in an oven. It’s a balancing act between the wattage and how fast that belt is moving. Keeping things running Most of these tubes use standard industrial connectors, so they’re pretty easy to swap out. We stick with quartz glass because it handles the heat swings well. Just a heads-up: they can still crack if something hits them or if they cool down too violently. You’ll want these wired into a PID controller. It stops the tubes from burning themselves out when the temperature jumps around. And one last thing: keep the glass clean. If grease builds up on the tubes, it blocks the heat. Your efficiency will tank, and you’ll be right back where you started.
