Refractance Window drying: Quality retention and energy efficiency

A multi-chamber dryer using adjustable conditioned counter current air flow with a low profile air tunnel system is disclosed. The present drying system enables the delivery of airflow to remain near the belt/product surface taking full advantage of the heat gain and the increased moisture capacity of the air flowing counter current respective to the belt/product flow. The present drying system increases and improves  a dryer throughput at steady state operation.
The conditioned air 210 travels through lower tubes 202 and 203 and the air is distributed across the entire width of drying belt 220. According to one embodiment, lower tubes 202 and 203 connect to horizontal manifolds 204 and  205 that have sanitary caps allowing for clean-in-place cleaning and easy disassembly and reassembly. Horizontal manifolds 204 and 205 include slits 206 and 207 through which the air 210 is injected into the drying chamber 208. Horizontal manifolds 204 and 205 may each have three openings, each opening having a narrow oval shape, according to one embodiment.

This review also includes an exhaustive summary on changes in product quality during RW™ drying of foods as compared to other drying methods such  as tray, spray and freeze drying, based on available published works till date. In comparison with several conventional drying approaches, RW™ drying is known to offer superior quality powders and flakes at relatively lower operation costs and time requirements. To give a complete understanding on the topic, aspects of energy requirements and thermal efficiency calculations are also presented.
Excellent actives and longer shelf life characterize products from Refractance Window dryers. Because these low temperature, atmospheric dryers have short dwell times, they better maintain natural color, flavor and aroma in your delicate products. Our current nutraceutical manufacturing clients have seen the benefits of how this drying Refractance Window Dryer process retains more nutrients in their products, helping them gain competitive advantage in their markets. Refractance Window drying is the cost effective alternative to freeze drying. In this work, unripe green banana flour was dried by using Refractance window drying and Hot Air oven drying, and various properties were evaluated.

3 illustrates a dryer exhaust manifold, according to one embodiment. Vega, A.; Uribe, E.; Lemus, R.; Miranda, M. Hot-air drying characteristics of Aloe vera and influence of temperature on kinetic parameters. Finally, significant losses of vitamin C were also reported in other foods such as guava pulp and doum fruits due to drying. Gel samples with 5 and 10 mm thicknesses dried by RW at different temperatures. In a matter of a few moments, the water in the material on the plastic membrane’s surface evaporates, and the “window” of infrared energy closes and “refracts” back into the heated water source, no longer exposing the material to heat. RW™ is a powerful tool that allows for the dehydration of fruit using temperatures of 95 °C and provides a 50% reduction in drying time.
Refractance Window drying is a safe way to dehydrate fresh whole foods. It gently extracts water from our foods while preserving vitamins, minerals, and micronutrients. Vivo Home  Dehydrator Manual. Web summary of contents for vivohome vh835.

MCD is better able to meet or exceed customer expectations due to the research work. We have also been empowered to assist some of our customers with these issues. “Hungry Giant is always improving the technology, and research is underway to find new heating methods to reduce energy costs and reduce the processing time,” says Sonny Burkett, president and cofounder of Hungry Giant Recycling. The system of claim 1, wherein the conditioned air supply manifold is coupled to a filtered air system for feeding conditioned air into the conditioned air supply manifold.
Gel could be reconstituted to a gel close to its fresh state by rehydration. Please let us know what you think of our products and services. •Energy consumption of the RW dryer was lower than SD and FD. We are more akin to a group of blind-from-birth people who have all simultaneously been given the gift of sight but have no words or mental processing capabilites to work with this new "gift". All these posts are on behalf of Stimpy, my yellow bullhead. He is an adventurous fish, and I feel his exploits are worth sharing...so much so, I occasionally forget that HE is the one who does these things.
The best dehydrators for jerky are models with powerful fan systems that evenly circulate the air in the dehydrator, allowing for better-quality jerky. Additionally, dehydrators with several trays or a large capacity allow users to make large batches of jerky at a time. Some dehydrators allow users to see each tray as the food is being dried. This is helpful if you want to keep an eye on what you’re dehydrating without opening the door or letting hot air escape.
