Recently introduced laser ovens have rapidly gained market share, particularly in efficiency-focused industries such as lithium-ion battery cell manufacturing and processes like drying or curing industrial coatings such as paint or powder coatings. High-efficiency laser heating solutions are poised to impact the food processing industry as low-carbon footprint alternatives to traditional ovens. Laser ovens efficiently process food with precise control, saving energy. Diode lasers, combining the lowest cost per watt with the highest energy conversion efficiency, emerge as the most suitable laser type for heating applications. Understanding more facets of laser processing is crucial to ensuring that valuable properties of foods, such as nutrition, taste, and texture, remain unaffected.
