IR D5 uses infrared to provide solar heat to dehydrate food. The internal material of the dehydrator is made of stainless steel to maximize the penetration and reflectance of near-infrared ray. Users can select the drying method which is solar-dried or air-dried. We’ve minimized the temperature difference among the trays and overall areas by placing the heater at the rear. The dehydration time is reduced by 20% compared to our previous model as the temperature difference is minimized. There are 5 slide in stainless steel trays and can dehydrate various sizes of food. Ideal fan balance and internally closed construction has reduced the noise.
