Frequently Asked Questions (FAQ)
Near-infrared (NIR, 0.75–1.4 µm) is ideal for deep penetration and rapid surface browning in baking. Medium-wave infrared (MIR, 1.4–3 µm) is best suited for drying and moisture removal. Far-infrared (FIR, 3–1000 µm) is used for gentle surface heating, pasteurization, and decontamination of low-moisture food products.
Depending on the application and product type, Kerone's infrared systems typically achieve 30 to 50% energy savings compared to equivalent-capacity hot-air convective dryers and ovens, due to the higher efficiency of direct radiant heat transfer and the elimination of air heating losses.

Yes, Kerone designs fully customized systems based on raw materials, capacity, temperature, and process requirements.
High efficiency, consistent output, energy savings, and process flexibility.
Yes, Kerone offers specialized low‑temperature and controlled‑heating systems.
Infrared food processing uses electromagnetic radiation in the infrared spectrum to directly heat food surfaces and near-surface layers through radiant energy transfer, eliminating the need for a hot air medium. This results in faster heating rates, lower energy consumption, and superior product quality compared to convective hot-air systems.
Infrared radiation transfers energy through electromagnetic waves that are absorbed primarily by the outer layers of most food products, since the radiation's penetration depth is limited by the material's optical and moisture properties. This surface-concentrated heating is precisely what makes infrared effective for blanching, surface pasteurization, and crust formation in baking, where the goal is rapid surface temperature rise without driving heat deep into the product core. For applications requiring uniform heating throughout a thick or dense product, infrared is often combined with other heating modes such as microwave or hot air rather than relied on alone, since its surface-limited penetration is a characteristic to be engineered around rather than a limitation to overcome.
Steam and hot water blanching transfer heat by convection across the entire product surface for an extended dwell time, which causes water-soluble vitamins and minerals to leach into the blanching medium, particularly with cut or sliced produce with high surface-area-to-volume ratio. Infrared blanching achieves the same enzyme-deactivation temperature at the surface in a shorter exposure window because radiant energy transfers more directly without an intermediate heat-carrying medium, reducing both leaching losses and overall processing time. The shorter exposure also reduces texture softening that's common with prolonged water blanching, which matters for products like vegetable chips where crispness after drying depends on minimizing pre-drying tissue damage.
Near-infrared (shorter wavelength, roughly 0.78 to 1.4 micrometers) penetrates slightly deeper and is often selected for applications needing some sub-surface heating effect, such as certain drying processes. Mid and far-infrared (longer wavelengths) are absorbed more strongly at the immediate surface and suit applications like surface pasteurization, browning, and crust development where deep penetration isn't desired. The selection depends on the food's optical absorption characteristics, which vary by moisture content, color, and surface texture, so equipment suppliers typically test wavelength response on the actual product rather than applying a generic wavelength choice across different food categories.
Scorching risk is managed primarily through precise control of emitter-to-product distance, exposure time, and emitter power modulation rather than relying on a single fixed intensity setting. Multi-zone infrared systems allow power to be reduced as the product approaches target temperature, avoiding the overshoot that occurs with constant-intensity exposure. Pulsed or cycled infrared operation, where emitters switch on and off rather than running continuously, gives the product surface time to redistribute absorbed heat between pulses, reducing localized hot spots. For delicate or high-sugar-content products prone to scorching, combining infrared with a moderate airflow across the product surface also helps dissipate excess surface heat without sacrificing the speed advantage infrared offers.
Infrared emitters gradually lose output efficiency as reflective surfaces behind ceramic or quartz elements accumulate residue from food particulates and moisture, so periodic cleaning of reflector surfaces is the most common maintenance task. Emitter elements themselves have a finite service life, typically ranging from several thousand to tens of thousands of operating hours depending on whether they're ceramic, quartz, or metal sheathed, and gradual output decline should be monitored with periodic radiometric checks rather than waiting for visible failure. Replacing emitters in matched sets rather than individually helps maintain even heat distribution across a processing zone, since mismatched emitter ages can create inconsistent heating patterns across the product width.
Convective hot air drying spends a significant portion of input energy heating the air itself, much of which is then lost as exhaust rather than transferring into the product. Infrared drying transfers radiant energy more directly to the product surface with less energy spent heating the surrounding air mass, which generally improves overall thermal efficiency for surface-moisture-dominant drying applications. The energy savings are most pronounced in early-stage drying where surface moisture removal dominates; as drying progresses and internal moisture diffusion becomes the limiting factor, the efficiency advantage narrows, which is why many systems combine infrared with convective airflow rather than using infrared exclusively through the full drying cycle.
Infrared pasteurization targets reduction of pathogenic and spoilage microorganisms to extend shelf life and improve safety while leaving some heat-resistant organisms and spores intact, which is acceptable for products that will be refrigerated or consumed relatively soon after processing. Infrared sterilization aims for a much higher degree of microbial lethality, including spore-forming organisms, to achieve commercial sterility suitable for shelf-stable, ambient-temperature storage. Because infrared's surface-concentrated heating profile makes it less suited to penetrating deep into thick products to achieve full sterilization, sterilization applications using infrared are typically limited to thin products or surfaces, with thicker or denser products requiring combination processing or alternative sterilization methods to reach the necessary lethality throughout the product.
Infrared emitter modules can often be retrofitted into existing conveyorized oven or dryer tunnels as a supplementary heat source, particularly when the goal is to add surface browning, faster initial moisture removal, or pasteurization capability without rebuilding the entire line. Retrofitting requires confirming that the existing conveyor speed range, tunnel clearance, and electrical supply can accommodate the added infrared load, and that control systems can coordinate the new zone with existing temperature and airflow controls. For applications needing infrared as the primary and only heat source rather than a supplement, a dedicated line designed around infrared's specific clearance and reflectivity requirements typically performs more consistently than a retrofit.
