REFRACTANCE WINDOW

Other authors have claimed the similarities between dried products obtained by freeze-drying and RW . Though, the RW drying systems are simple and relatively inexpensive when compared with freeze-drying, which usually needs large installations to be economical . Hence, according to the savings in energy, from the commercial point of view, the RW technique might be a low-cost scalable option for the continuous production of high-quality dried products . Energy requirements of any unit operation are crucial in the industry perspective. In this regard, the thermal efficiency of an RW drying system is usually in the range of 52–77%, which are values comparable to drum drying .
Using specialised machinery like refractive window food drying systems will make the task easier. Purchase it from Food Tech Projects, which is one of the leading manufacturers of such equipment in India. Our drying equipment is known for its functionality, ease of use and dynamic industrial design. Fan systems inside dehydrators allow the hot air to evenly circulate, ultimately resulting in a better-dried food product. Energy efficient and with low water use, Refractance Window® drying preserves air quality in and around the drying facility because little product essence is lost. In addition, the process does not generate exhaust dust, a significant pollution problem.

The study concluded that solar drying processes with thermal energy storage devices based on natural materials are most preferred for delivering extended shelf life for farm produce in an energy-efficient and sustainable manner. Gel has been dried by several methods for preservation, such as hot air drying , spray drying , osmotic dehydration , and combined methods such as hot air in combination with far-infrared radiation and high-voltage electric field . When drying foods, a very important factor is to achieve good quality indicators such as color, flavor, texture, nutrient availability, among others; all of which determine the food’s value and consumer acceptance on dehydrated food products . However,  in most cases, these conventional drying methods produce inferior quality products and require higher drying times .
Samples were filtered through 0.45 μm PVDF membrane and deposited in 2 mL amber vials. The standard vitamin E concentration was 0.77 mg/100 g solid. Sample peaks were identified according to retention time and absorbance Refractance Window Dryer spectra compared to standards. The minimum detection level of the HPLC chromatograph was 0.05 mg/100 g solid. Gel drying were fitted to five empirical kinetic models widely used in food drying and shown in Table 1.

As the material travels down the conveyor, the water in the material evaporates through the “window” in the matter of few moments, with the “window” closing in proportion to the rapid dissipation of water in the material. Because the Mylar conveyor belt is a poor heat conductor, once the material dries, the “refractance window” closes, and only a minuscule amount of heat is transferred to the product as it is carried to the end of the conveyor system. Changes in curcuminoids and chemical components of turmeric (Curcuma longa L.) under freeze-drying and low-temperature drying methods. The method of claim 10, wherein the conditioned air flows parallel to the direction of travel of the product on the belt. Directing the conditioned air through air slits, connecting the at least one or more horizontal manifolds to the drying chamber.

According to one embodiment, each opening of slit 206 and slit 207 is approximately one sixth the width of the dryer belt 320. In another embodiment, horizontal manifolds 204 and 205 each have a single opening, where each opening is approximately one half the width of the drying belt 220. According to one embodiment, horizontal manifold 204 has a length that is half the width of drying belt 220. Horizontal manifold 204 may have a diameter of approximately six inches.
These machines utilize programmable logic controllers that measure the amount of moisture as it is being evaporated during the process to power down the machine as compared to machines that operate on timers only. The method of claim 15, wherein the cooling capacity is 290 MBH and the heating capacity is 328.1 MBH. The system of claim 1, wherein the exhaust manifold comprises an exhaust fan assembly. The manifolds described above may be made of food grade aluminum or stainless steel, according to one embodiment. In alternate embodiments, the manifolds are made of high temperature plastic such  as PVC, or a combination of PVC and metal.
The rapid depletion of non-renewable energy sources, along with rising environmental concerns, are opening up new opportunities for developing sustainable drying systems and reducing its carbon footprint. Drying modelling is a powerful tool for understanding the mechanism and predicting fluid flow hydrodynamics and heat and mass transfer during the drying process. First, the drying mechanism and novel drying technologies are explained. Then, various modelling methods are summarised. Finally, new insights into quality and energy modelling using CFD are discussed.
