Dedicated whole-muscle charcuterie fridge
A refrigerator set aside for curing whole cuts of meat, held at a cool curing temperature and humidity under an external controller with airflow and hanging space.
Overview
A dedicated whole-muscle charcuterie fridge is a refrigerator kept for curing whole cuts. Its controller holds a cool curing temperature and humidity, and its racks hang the pieces with airflow around each one.
The consulted sources describe curing chambers in general terms. They do not give a cure schedule for whole muscle.

Temperature and humidity
Curing guides put the target at 10 to 15 C and 70 to 80 percent relative humidity, with about 5 percent tolerance. A fridge without a freezer compartment is preferred because it is easier to humidify.
Temperature swings of about 1 to 2 C are described as normal with a controller in charge.

Mould and case hardening
Surface mould is expected in a curing chamber. A white mould is considered beneficial, and other mould is wiped off with vinegar. Case hardening, a dried crust over a moist interior, is treated by vacuum-sealing the affected piece and storing it in a standard fridge for 4 to 8 weeks.

What is not established
No consulted source gives a cure schedule, salt level or water activity target for whole-muscle products. These require a product-specific source and validation.

How it is built
Risks and precautions
Excess moisture lets unwanted mould grow; a white mould is expected and other mould is wiped off with vinegar.
Hazard sourceA dried outer layer can seal the inside; the guide describes vacuum-sealing and storing affected pieces.
Hazard sourceRacks must carry the hung weight.
Hazard sourceLog temperature and humidity with a probe before and during curing.
Control sourceNot a validated curing process. Salt, time and water activity limits for whole-muscle products are not established by the sources consulted.
Materials
- 1 unit Refrigerator without a freezer compartment — Non-frost-free design is easier to humidify; freezer compartments are not needed.
- 1 unit Temperature controller — Overrides the fridge thermostat and cycles the compressor.
- 1 set Ultrasonic humidifier and humidity controller — Adds humidity to a fridge that runs dry.
- Hanging racks — Test with weight before loading meat.
- 1 unit Small fan — Run a few minutes a day; position it so that it does not blow directly on the meat.
- Clean the interior with diluted bleach or plain vinegar, and remove shelves and drawers.
- Set the fridge thermostat to its coldest position and let the external controller cycle the compressor.
- Place the temperature probe in the middle of the chamber and the humidity probe away from mist output and vents.
- Add humidity with an ultrasonic humidifier and keep the mist away from the meat.
- Test the racks with weight, then hang the pieces with space between them so that air reaches all sides.
- Run the fridge for 48 hours with the fan before loading meat, and log temperature and humidity.
- Avoid frequent door openings. Vacuum-seal any piece that case-hardens and store it in a standard fridge for 4 to 8 weeks, as one guide advises.
