Proofer FM industrial STF 633

A proofer creates the warm, humid environment dough needs to rise before baking. The FM Industrial STF 633 circulates heated, moist air around stacked trays of dough, keeping the temperature and humidity steady so the yeast ferments evenly. Without this controlled climate, dough would rise too quickly or too slowly, producing bread and pastries of uneven texture and volume.

The operator loads the trays—either five 800 by 600 mm or ten 600 by 400 mm—onto the internal racks, spacing them 80 mm apart to allow air to flow freely. A digital control panel sets the temperature up to 85 °C and starts the programme. A push-button fills the water tank from a 3/4" connection, maintaining the humidity level automatically. Once the cycle finishes, the trays are removed and transferred directly to the compatible FM Industrial STZ 633 oven.

The cabinet is built to fit standard bakery trays and stands on a footprint of 1500 by 985 mm, taking its place alongside other worktop equipment. The 2.1 kW heating element draws power from a 230 V single-phase supply, typical of professional kitchens. At 105 kg, the unit is moved with a trolley but stays stable once positioned.

Cleaning follows from the construction: the water tank and tray runners are wiped after each use, and the interior is washed weekly to prevent flour and moisture build-up. The digital controls require no calibration, and the 3/4" water connection is standardised for easy maintenance.

The STF 633 is listed in the FM Industrial bakery range under proofing equipment.
