2021Resumen
In this research, a closed-flow solar dehydrator with a refrigeration moisture extraction system was evaluated, likewise, the dehydration temperature time was optimized by evaluating
three types of heat transfer fluids. The dehydration equipment included devices to absorb
thermal energy from incident sunlight, such as a trombe wall and a parabolic cylindrical collector, and a thermo bank system. In addition, the influence of three types of heat transfer
fluids (water, oil and oil nanofluidþ silver nanoparticles) was evaluated. This dehydration
system was applied to process the Pouteria lucuma fruit. The results indicate the reduction
of the dehydration time by 58.19% using nanofluid. This treatment prevents the modification of the physicochemical properties of the product and helps preserving its organoleptic properties.
