Fruit dehydration needs low temperature to keep color, sugar, and vitamins, and its exhaust is warm and very humid - exactly the conditions where enthalpy recovery pays off.
Enthalpy wheels recover both heat and moisture, lightening the refrigeration or desiccant dehumidification load of the dryer and steadying the drying air.
Sugary, sticky condensate and food-grade hygiene require stainless, easy-clean, washdown construction and disciplined sanitation to prevent microbial growth.
Control RH and temperature to the fruit's drying curve, use a bypass in the early phase, and validate cleaning. Expect 25-45% energy savings with better texture and nutrient retention.
