Getting Your Fruit Export-Ready: The Truth About Infrared Drying

If you’re shipping dried fruit internationally, you know the struggle. You have to hit those strict food safety moisture levels, but if you push the heat too hard, you end up with scorched fruit that nobody wants to buy. It’s a delicate balance. That’s where our infrared (IR) radiators come in. We build these specifically for the heavy lifting required on continuous conveyor lines. Let’s talk power. Depending on where you’re located, we spec our units between 220V and 400V. Here is the trick: higher voltage lets us pack more wattage into a smaller space. For you, that means the heat ramps up faster and your drying tunnels can be shorter. It saves space and time. Just a heads-up—make sure your control panels can actually handle the amperage these lamps pull. If they can’t, you’re going to be tripping breakers right when you’re in the middle of a big run. Why the quartz matters. Inside the lamps, we use high-purity quartz glass to protect the tungsten filaments. This isn’t just for durability. The quartz lets shortwave IR radiation slide right through. Instead of just searing the skin of the fruit, this heat sinks deep into the pulp and pushes the moisture out from the core. And if you’re working with high-sugar fruits that caramelize (and burn) too quickly? We’ve got coated options to tweak that heat spectrum so you don’t ruin your batch. Keeping the line moving. Nothing kills a workday like a burned-out lamp that takes three hours to replace. We hate that as much as you do. That’s why we use standard R7s or Sk15 connectors. They’re basically “plug and play.” Your techs can swap a tube in a few minutes and get the line moving again. One last thing: these radiators put out a massive amount of heat. If your conveyor housing doesn’t have great ventilation or shielding, you’re just trapping that heat around the sockets. Do that for too long and you’ll fry your wiring. My advice? Have your team check the contact points for oxidation every 500 hours. It’s a quick check that saves a massive headache later.
