Abstract:
Refractive window drying is a novel drying method used for drying of slices, puree and juice of fruits and vegetables. In this method, product spread on the Mylar film forming thin layer. When the hot water below boiling temperature circulates in contact with below film. Thermal energy of the water receives by the product and moisture from the product removes. Refractive window drying is energy efficient and quick drying method and requires less energy and cost of operation. It helps to maintains better dried product quality in terms of nutrient and sensory attributes. This article reviews the working principle, mechanism and energy efficiency of refractive window drying. Also tries to highlight required development and future scope of refractive window drying method.
