Abstract

Embodiments herein include devices adaptable to dehydrate articles, including foods. Embodiments are shown which can be compacted for reduced storage, and/or shipping requirements and/or for other purposes. Embodiments include simple, inexpensive means for controlling dehydrating conditions, including airflow. Various article holding devices, including devices to hold foods being dehydrated, are also shown. Such devices include vertical, diagonal, and horizontal panels to secure articles. Embodiments shown have variations which include the use of non-motorized convection airflow, as well as devices which incorporate motor driven air movement means. Embodiments are shown which may be used for preparing articles, including foods, for dehydration, including slicing such articles.
