ABSTRACT Desiccant drying technologies have gained attention for their ability to efficiently remove moisture from air, which is crucial in various applications, like in agriculture and post‐harvest management. The integration of advanced systems, such as hybrid solar air collectors and rotary solid desiccant dehumidifiers, has been explored to enhance dehumidification performance and energy efficiency. This work reviews the evolution of desiccant drying technologies over the past decade. The approach includes a bibliometric analysis of the data that quantitatively and qualitatively assesses the research landscape, mapping key trends, research clusters, and emerging topics within the field. This paper allows for a structured overview of advancements and challenges in desiccant drying systems. Desiccant‐based systems outperform conventional drying methods by reducing energy use and preserving product quality. However, the existing technologies have limitations and require further optimization. The study concludes that while progress has been made, challenges remain, urging future research into innovative materials and designs for better efficiency and sustainability. The novelty of this work lies in its bibliometric approach, offering a structured overview of the field and highlighting the potential of desiccant technologies over traditional methods.
