Food-grade tote with low-voltage extraction fan
A washable food-grade tote with removable rails, insect screens, a drip tray and a low-voltage extraction fan, a simple dryer for biltong that avoids rebuilding a refrigerator.
Airflow
Guidance for passive biltong boxes puts the intake low and the exhaust high, with mesh over the vents. A fan running continuously is the main moisture remover in those designs.
The brief asks for the airflow actually delivered through the mesh and guards, not the fan rating.

Biltong Box Design and Build GuideTargets of roughly 25-30 C at 40-60% relative humidity; if humidity stays above 60%, add airflow, more bulb heat or a dehumidifier.
Intake vents low, exhaust vents high; mesh over vents keeps insects out.
A 120 mm computer fan is the main moisture remover; a 15-40 W incandescent bulb gives gentle warmth; keep the interior under about 35 C.
Plywood is the author preference; stainless S-hooks or food-safe twine; avoid galvanised hooks touching the meat.
Hang pieces so none touch; run the empty box for an hour and check a digital hygrometer before use.
