Dehumidification module for a food chamber
A method for sizing a dehumidifier for a food chamber from water removed per day at the working temperature and humidity, not from a warm-room headline rating.
Measure the water removed
The brief asks for grams of water removed per day at the working temperature and humidity. It names the EDV-1100 rating conflict as a concrete case: the figures do not agree, so the rating cannot be used unchecked.
Air exchange has to be compared on moisture content or dew point. Two relative humidity figures, one indoors and one outdoors, do not show whether incoming air will add or remove water.

When dehumidifying is the fix
Guidance for biltong drying names a dehumidifier as one of three remedies when humidity stays above 60%, alongside more airflow and gentle heat.

Equipment details
Made of
- Dehumidifier or the refrigerator own condensate removal — Rated for the working conditions
Model not chosen - Conditioned air exchange — Compare moisture content or dew point, not relative humidity alone
Limits
Warm-room headline capacity overstates the water a unit removes at chamber conditions; measure grams per day at operating temperature and humidity.
SourceHeat from the unit enters the cabinet, and reservoir-full behaviour changes performance; both must be measured.

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.
