Stop Wasting Money on Heat: A Real Look at IR in Fruit Processing
In the fruit and veg business, we all know the deal. Margins are razor-thin. You’re basically fighting a war over a few cents per unit. When it comes to infrared (IR) radiators, a lot of people think the most expensive lamp is the best one. But that’s not how it works. The real trick is matching the wavelength and power density to how fast your line is moving. That’s where you actually save on the power bill. Getting the heat right We build our radiators to keep up with the chaos of a high-speed food line. It comes down to the wattage-to-length ratio. If you get that right, you can hit your target temperature fast without scorching the skin of the fruit. Plus, using higher wattage tubes means your tunnels can be shorter. You get the same heat, but you save a ton of floor space. The nitty-gritty on materials We stick with high-purity quartz glass because it lets the IR light through without any fuss. For fruit plants, we usually suggest specific coatings. Why? Because you want the heat to actually sink into the produce, not just warm up the air around it. And we didn’t overcomplicate the plugs. We use standard R7s or SK15 connectors. If a lamp burns out, you just pop a new one in. No need to call an electrician to rewire your entire control cabinet. The catch (and how to handle it) Switching to high-efficiency IR lamps is a great way to drop your kilowatt-hour cost per ton. It’s a direct win for your bottom line. But here’s the thing: high-intensity short-wave lamps put out a massive amount of heat in a tight spot. If your conveyor housing isn’t vented well or your fans are too small, you’re going to bake your own electronics. Before you crank up the wattage, take a look at your airflow. Get the specs right, and you stop paying to heat the room.
