ABSTRACT:
A solar drying device for drying wet material. The device includes an air-filled drying chamber adapted to contain wet material to be dried. A solar collector heats the wet material and air contained within the drying chamber. A dehumidification system includes a dehumidification chamber defined in part by an outer panel and an inner panel, the outer panel being in contact with the ambient atmosphere. The dehumidification chamber forms at least part of a wall of one of the drying chamber and the solar collector. Means are provided for directing warm, moist air from the drying chamber through the dehumidification chamber so that water from the moist air condenses on the outer panel. The air is then directed to one of the drying chamber and the ambient atmosphere. Means are provided for removing the condensed water from the dehumidification system. Thus the solar drying device provides that at least one of the drying chamber and the solar collector may be thermally insulated from the ambient atmosphere in part by the dehumidification chamber.
