OPERATION AND CARE OF
PROOFERS & RETARDER/PROOFERS
SAVE THESE INSTRUCTIONS
GENERAL
The Proofer and Retarder/Proofer cabinets proof racks of dough products under controlled temperatures
and humidity prior to baking. There are several to choose from. The standard proofers are equipped to proof
dough only. Retarder/Proofers gradually thaw frozen dough. The retarders operate like a refrigerator by
keeping the interior cool, which also provides an excellent environment for storing dough prior to proong.
The cooler temperature slows the yeast fermentation process and prevents the dough from rising. The
Automatic Retard/Proof feature adds the exibility of programming times to retard and automatically proof
in one operation.
The Proofers and Retarder/Proofers o󰀨er a unique modular design, allowing for a wide variety of sizes
in standard models. They can be ordered as one-, two-, or three-section roll-in models. All Proofer and
Retarder/Proofer cabinets have easy-to-clean stainless steel interior and exterior panels.
It is suggested that you thoroughly read this manual and carefully follow the instructions provided.
INSTALLATION
Proofers and Retarder/Proofers must be installed by authorized trained service technicians.

OPERATION
The following pages cover the operation procedures for the various control options of the Proofer
and Retarder/Proofer cabinets. The control panels come in two congurations: standard proofer and
retarder/proofer.
PROOFING
Controlled temperature and humidity in the proofer promotes yeast fermentation, which generates gas and
causes the dough to rise. Proong takes from 45 to 60 minutes, depending on the product. A temperature
setting of 95°F (35°C) and humidity at 85% are typical but will vary slightly, depending on the product
being proofed. To dry-proof, set the humidity to the lowest setting. The chart below is only a guide. Ask
your dough supplier for technical product reports to set up your own chart.
RETARDING
The retard feature gradually thaws frozen dough. Set the temperature between 36°F and 38°F (2°C
to 3°C) for best results. Thawing frozen dough at retarder temperatures takes approximately 6 hours
minimum. Retarding slows the yeast fermentation process, reduces gas formation and inhibits the dough
from rising. This also provides an excellent environment for storing dough products up to 48 hours by
keeping the dough interior cool. Dough should not be refrozen after thawing.
It is likely that condensation will form if product is placed directly into the proofer from the retarder. For
best results, allow the product to reach room temperature before placing into the proofer.
Units equipped with auto mode will slowly and automatically bring the proofer up to temperature without
removing the product from the unit.
Product Proong
Temperature % Humidity Proof Time Minutes
Rolls 95°F (35°C) 85% 55 min.
French Crust Bread 14 oz. 90°F (32°C) 90% 45 min.
