The efficiency of fruit drying is largely determined by the interaction between the technological parameters of the drying process and the biological and physicochemical characteristics of the raw material. Quince (Cydonia oblonga Mill.) is considered a promising raw material for dried fruit production due to its relatively high content of dry matter, sugars, organic acids, pectin substances, and other valuable components. However, the dense tissue structure of quince may restrict moisture migration and prolong the drying process, resulting in increased energy consumption. The present study aimed to evaluate the technological efficiency of combined convective–infrared drying of seven quince cultivars: Samarqand yirik mevasi, Toshkent yumaloq behi, Andijon behi, Qo‘qon behi, Desertnaya, Krupnoplodnaya, and Maslyanka pozdnyaya. The experiments were conducted during 2023–2025 under laboratory and semi-industrial conditions. Drying performance was evaluated according to drying duration, final moisture content, dried product yield, reduction in drying time, and reduction in energy consumption.
