Hot air oven was used to determine residual moisture in mango leather after completion of drying process. Desirable moisture content in the mango should be in the range of 15–25% to categorise it as intermediate moisture food (Shende et al. 2016; Kaur et al. 2017). The leaves were washed with potable water; the outer layer rind was removed from the gel; then, slabs 25 mm long, 15 mm wide, and of two thicknesses were prepared. A slab geometry was selected, as it is an easy way to cut the sample at an industrial level. In addition, this was the geometry analyzed for the mathematical modeling of the drying kinetics. Different studies on energy consumption and energy efficiency of RW drying have concluded that in comparison with different conventional drying methods, RW drying is a very energy efficient choice .
Phage Felix O1 powders were placed in sterile polypropylene falcon tubes and stored for 180 days at room temperature. D values of phage Felix O1 powders produced by freeze drying, spray Revolutionizing Food Drying: The Advantages of Refractance Window Dryer drying and electrospraying were 11.52, 16.65 and 6.20, respectively. The highest bulk (0.68) and tapped density (0.93) values were found in powders produced by electrospraying.

In a Refractance Window Dryer, the food is not directly exposed to extreme hot or cold temperatures during drying. It is instead based on the transfer of thermal energy from warm water to food. This continues until a precise point of dehydration is reached, at which point the drying process automatically stops. Several methods of food drying have been developed but none provide economical and high quality products . Freeze drying is considered one of the best food processing methods to produce high-quality dehydrated food, but it is a costly and time-consuming process. Variation of moisture content with drying time for refractance window drying , oven drying , and solar drying .
Conditioned air supply manifold 500 also includes a supply opening 520 that extends from the hexagonal body 510 where two sides approach each other. 4 illustrates an exemplary side view of the conditioned air supply manifold 400, according to one embodiment. Conditioned air supply manifold 400 has a circular body 410 that according to one embodiment has a six inch diameter. Conditioned air supply manifold 400 also includes a supply opening 420 that extends from the circular body 410. Dryer exhaust manifold 300 has a rectangular opening 301 that intakes moist air 310, and pulls up moist air 310 through tube 303 by using an exhaust blower 340. According to one embodiment, exhaust opening 301 has a width that is approximately the width of drying belt 320.
However, this macroscopic approach to quantify the transport of water during the first falling rate period of drying commonly involves the determination of an effective water diffusivity .

Production of tomato powder by refractance window drying. The total flavonoid content was quantified following the colorimetric method described by Zhishen et al. , using rutin as a standard and performing spectrophotometric reading at 450 nm . The results were expressed in milligrams of rutin per 100 g of sample .





The results revealed that the moisture and water activity in Açaí dried powder using the RW dryer was higher than those in the other two drying methods. The Model 1 Refractance Window™ Dryer pictured on the right features state-of-the-art laser cut components manufactured with a modular design for full scale-up capabilities. The drying process is both effective and efficient, offering excellent results with a wide variety of foods and other products requiring precise, low temperature drying. Refractance Window™ dryers offer a number of superior customer benefits over other drying methods currently in use, including capital equipment costs up to 80% lower and energy costs up to 50% lower.
We believe that our industrial dryers are not just machines, but solutions that can help transform business. Table 5.Effects of process factors on the drying yields (g/h-m2).

The analytical solution is given by , which is valid only for the falling rate drying period. Where Xt is the moisture content at a given time, Xe is the equilibrium moisture content and X0 is the initial moisture content (g water/g dry solid). However, MR was simplified to , taking into account that the RW™ equipment used for the experiments does not control the relative humidity of air in contact with the material [21-23]. The drying kinetics were fitted using Newton's and Midilli's models, widely used for modeling moisture ratio in biological materials [19-21].
Through this process, evaporated water from the product is removed resulting in the formation of dried crystals. According to one embodiment, conditioned air is air that has a predetermined humidity and temperature. The humidity and temperature of the conditioned air may be specific to the types of products being dried.
