Comparing Infrared and Induction Heating for Moisture Removal in Can Sealing

Drying Your Can Seals: IR vs. Induction

If you’ve got water hanging around the sealing zone of a can, you’ve got a problem. It’s a recipe for rust and bacteria, and neither of those belong in your product. To fix it, you basically have two options: induction heating or infrared (IR) lamps. Here is the real-world difference. Induction is great at heating up the metal itself. It gets the can wall hot, and it does it fast. But there’s a catch. It’s a bulk heating process. It doesn’t really “see” the water droplets sitting on the surface; it just cares about the metal. That’s where shortwave IR lamps come in. Think of IR as a targeted strike. The radiation hits those water droplets directly, turning them into vapor almost instantly. By the time the seam is actually crimped, the area is bone-dry. It just works. Plus, there’s the hygiene side of things. In a food plant, the last thing you want is oil or weird conductive fluids leaking onto your line. IR lamps are completely non-contact. We tuck them away in quartz sleeves or stainless steel housings, so nothing ever actually touches the can. No touch, no cross-contamination. Simple. Induction is a bit more finicky. You have to get the coil positioning exactly right. If a coil shifts even a little, you end up with hotspots. IR is much more forgiving—it gives you a wider, more even heat footprint. Now, I’ll be honest: IR isn’t a magic fix for everything. Those high-wattage lamps put out a lot of heat. If you don’t set up your ventilation or cooling fans correctly, you’re going to end up cooking your own electronics. You have to plan for that. So, if you just need the metal to be hot, induction is fine. But if your goal is to kill the moisture and keep things sterile? Go with IR. It’s the only way to be sure that sealing zone is totally dry before the lid drops.

Using Infrared Preheaters to Eliminate Residual Moisture in Milk Powder Can Sealing

Getting the Moisture Out of Milk Powder Cans

Here’s the deal: if there’s even a tiny bit of moisture left on the sealing rim of a milk powder can, you’ve got a problem. When that water gets trapped during crimping, it’s basically an open invitation for bacteria to move in or for the powder to spoil way too early. To stop that from happening, we use infrared (IR) preheaters to flash-dry the rim right before the can hits the seamer.

Using Infrared Curing Lamps to Eliminate Moisture in Can Seaming Zones

Stop Trapping Water in Your Can Seals

If you’ve got moisture hanging around the seaming area of a can, you’ve got a problem. It’s a recipe for contamination or, even worse, a seal that just fails. To fix this, we use short-wave infrared (IR) curing lamps to basically flash-evaporate those tiny water droplets right before the seal locks in. It’s more than just drying things off. It’s about building a wall against bacteria.
