The drying chamber has the shape of a parallelpip with its longitudinal axes in the North-
South direction. A wooden frame supports a transparent polycarbonate hollow plate 4.5 mm
thick. The wooden skeleton and polycarbonate plates are screwed together allowing the whole
chamber to be disassembled easily. The construction is modular to permit variations of the
drying chamber capacity. Trays have a shape that they can be piled easily without crushing
the fruits and allow air circulation between them following the main axis. Four small
windows located at the far ends of the chamber enable introduction of measuring devices and
also control the air rene wal in the system. Eight fans placed inside the chamber produce and
internal recycling, and cause the air flux to be uniform. The drying system has six solar
collectors made of blackened iron plate, protected by a glass cover, which also helps to
decrease heat losses
