Conteúdo: | The economy of medicinalplant production is burdened considerably by the energy costs of dryng. To substitute fossil energy, a solar heated dryer was developed, taking a plastic film greenhouse as superstructure to lower the initial costs. The solar air heaters, being incorporated into the roof, consist of a black absorber tissue, which is placed between the transparent cover of the greenhouse and an insulating air-bubble foil. To obtain a modular design, the system is structured alog the ridge into segments of 2 m width. Each segment forms an independent solar air heater/ batch dryer unit and is operated by a fan with apower consumption of 500 W. A prototype was tested in Yugoslavia, dryng mint, sage and hops. The dryng process from an initial moisture content of 11% w.b. took 3-4 days.
