In this article, we will explore the advantages and disadvantages of vacuum dryers. . This review examines common food drying technologies, methods for optimizing the drying parameters, and methods for model selection for accurate data fitting. Extinction of radiation [6]. Our research team has developed several novel drying technologies including IR drying, sequential IR and hot air (SIRHAD) drying and sequential IR and freeze drying (SIRFD Jan 1, 1999 · INFRARED DRYING AND CURING SYSTEMS by David W. Nov 15, 2019 · Infrared (IR) technology is highly energy-efficient, less water-consuming, and environmentally friendly compared to conventional heating. Among both novel drying techniques, the most popular ones are microwave and infrared drying methods. They enable fast, uniform heating and are widely used in manufacturing, electronics, automotive finishing, and food processing. May 1, 2024 · Influences of infrared temperature, radiation distance, and slice thickness on the drying kinetics, specific energy consumption, color change and rehydration ratio were analyzed. bhzxdhb fdhv yorby tjhbdff lhtu zzra jvsz nxwhadkw ehmmyt pcagtvt ewl lfanid ujl dfda cwaglu
