OPERATION AND CARE OF
MODELS HPC100, 200, 300 PROOFERS &
HRP100, 200 RETARDER/PROOFERS
PLEASE SAVE THIS MANUAL FOR FUTURE REFERENCE

GENERAL

The HPC Proofer and HRP Retarder/Proofer cabinets proof racks of dough products under controlled temperatures and humidity prior to baking. There are several options to choose from. The standard proofers are equipped to proof dough only. Proofers with Fas-Thaw quickly thaw frozen dough. The Automatic Thaw/Proof feature adds the flexibility of programming times to automatically thaw and proof in one operation. Proofer/Retarders gradually thaw frozen dough. They operate like a refrigerator by keeping the interior cool. They also provide an excellent environment for storing dough. The cooler temperature slows the yeast fermentation process and prevents the dough from rising. The Automatic Retard/Proof feature adds the flexibility of programming times to automatically retard and proof in one operation.
The HPC Proofers and HRP Retarder/Proofers offer a unique modular design, allowing for a wide variety of sizes in both standard and pass-through models. They can be ordered as one-, two-, or three­section roll-in or roll-through models. All HPC Proofer and HRP Retarder/Proofer cabinets have easy­to-clean stainless steel interior and exterior panels.
Models HPC100, 200, and 300 Proofers and HRP100 and 200 Retarder/Proofers must be installed and serviced only by authorized Hobart Bakery Systems trained service technicians.
It is suggested that you thoroughly read this manual and carefully follow the instructions provided.

OPERATION

The following pages cover the operation procedures for the various control options of the HPC Proofer and HRP Retarder/Proofer cabinets. The control panels come in four configurations: standard proofer, proofer with Fas-Thaw, proofer retarder, and proofer/retarder with Fas-Thaw.
START-UP
The HPC Proofer and HRP Retarder/Proofer cabinets have two toggle switches located above the main control panel marked OFF/ON LIGHTS and OFF/ON POWER.
OFF ON
POWER
1. To power up the HPC Proofer and HRP Proofer/Retarder cabinets, flip the toggle switch marked POWER to the ON position.
2. The control display will light up, all other functions - proof, thaw, retard, or automatic cycles (depending which model) - will not be active until that specific function key is pressed.
3. To turn on the interior lights, flip the toggle switch marked LIGHTS to the ON position.
4. You are now ready to begin proofing operations.

PROOFING
Controlled temperature and humidity in the proofer promotes yeast fermentation which generates gas and causes the dough to rise. Proofing takes from 45 – 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 for guidelines only. Ask your dough supplier for technical product reports to set up your own chart.

RETARDING
The retard feature gradually thaws frozen dough. Temperature is set between 35°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 interior cool. Dough should not be refrozen after thawing.
Products removed from the retarder should be left at room temperature for 5 to 7 minutes before they are put in the proofer. This will reduce moisture condensation when cold metal pans are placed in the warm humid proofer.
