4. Conclusion
This investigation demonstrated that the solar dehydrator system can be used for conserve the proprieties of the chamomile during dehydration. The system implemented produces larger amount of thermal energy without noticeable increase in the system’s cost. The samples obtained by the dehydrated fulfill satisfactorily the parameters established in the normal. The physical and chemical properties of aromatic and medicinal plants are determined by their moisture content. Drying process may also contribute to a regular supply and facilitate the marketing of plants, because drying results in reduction of the weight and volume of the plant with positive consequences for transport and storage.
