Manufacturers Introduction
TheDukeAHPOorEPOProoferOvenwere developed
in response to Customer’s need for uniform baking
capabilities to provide consistently high, “just baked”
breadquality.
TheDukeProoferOvenutilizesDuke’suniquedirectional
convection airflow technology that provides even heat
distribution and a uniform bake without the need for
turningpans during thebakecycle. Thisenhances the
quality and consistency of the baked products while
reducing food scrap/waste and simplifying operating
procedures.
Thelowprofileovenwon’tblocktheviewof menuboards
and will easily roll through a standard height door.The
oven and proofer doors are field reversible with a drip
channel on the proofer door to prevent water from
drippingonthefloor.
Fullwidthdoors on the ovenandprooferhelptodisplay

•Turn the proofer powerswitchon and set theprooferheat to thedesiredtemperature.Agoodstartingtempera-
ture is 105°F.
•Thelight above the heat thermostat will be on until the proofer has heatedto the set temperature.
•You may needto adjust thistemperature depending onyour results.Do not turnon the prooferhumidity at this
time.
•After the proofer has been heating for 20 minutes, turn the humidity switch to a setting of #3 or 4.
•You may need to adjust this setting depending on your results.
•When a light fog appears on the door glass the proofer is ready to load with dough.
•The humidity setting is too high if water is running down the door glass.
•If the door glass does not fog then the humidity setting is too low.
•Loadthe prooferwith breaddough andset thetimer for50 -60 minutes.
•You may need to adjust the time depending on the type of dough and your results.
•When it rises to 75 - 80 % of it’s final size, it is ready to bake.
•Sincetheproofercanholdmore pans of bread than theovencanbake,staggerthe loading in increments of the
ovenbaketime.This will prevent over proofingofthebread remaining in the prooferafterthefirst load is moved
totheoven.
•Ifthere is excessivehumidity on thedoor glass itis probably caused by a humidity setting thatis too highor by
havingthe humidity on whenthere is nodough loaded inthe proofer.

•Run the proofer humidity without a load of dough.
ItisOKto leave the prooferheatonto maintainthetemperature,but turn the humidityoffiftheprooferisempty.
•Let the dough dry out while it is thawing.
Dough that is too dry will not fully rise in the proofer and may crack.
•Over-proof the dough
Excessive proofing will cause the bread to collapse after it has been baked. Make sure to adjust the proofing
timetopreventover-proofing.
•Under-proof the dough
If the bread is under-proofed it will not bake to the proper finished size and will have a dense cell structure.
•Proof frozen dough
Makesure the doughis thawed properlybefore loading it into theproofer.Thedoughshould be softandmoist
withthe center thawed.
DO…
•Watch the proofing process carefully and make adjustments if necessary.

be ready to bake when the first load is ready from
theproofer.
•Theovenpreheat time should befrom 20 to 30min-
utes.Theovendoorshouldbeclosed,exceptduring
loading and unloading. Load the oven quickly to re-
duce heat loss.
•Loadtheovenwith6pansofbread and set the bake
timer. The bake time can be adjusted to get the de-
siredcolor of thebaked bread.
•If the baking results are uneven or too dark, reduce
thetemperature and extend the bake time.
•If the bread is too dark, reduce the bake time. If the
bake time is reduced and the bread is still too dark
then reduce the temperature 15° F (10° C) and try
baking for a longer period of time. The same proce-
dure can be used to bake Deli rolls.
•If you are baking partial loads try to center the pans

OVEN AND PROOFER TEMPERATURE CHECK
Ifthe oven orproofer temperature calibration seems tobe wrong, itcan be checked before aservice call is made.
Itis important tofollow the correct procedure toget an accuratereading. If the calibration isoff it is recommended
that you first call Duke Manufacturing Co. and talk to the service department before you schedule a service call.
Calling Duke first can save you time and money by eliminating other problems before a service call is made.
Themostimportantconcernwithtemperaturemeasurement is the accuracy of the thermometerandthelocationin
theoven cavity. Duke recommendsan electronic temperature meterwith a wirethermocouple.
1. Place the thermocouple at the geometric center of
the oven cavity. It can be fastened to the center of
themiddle wire shelf.
2. Start the oven and set the temperature control for
350° follow the oven to pre-heat for at least 45 min-
utes.
3. While watching the heat light on the control panel,
note the maximum and minimum temperatures
throughseveralcycles.
4. Theaveragetemperatureofseveral cyclesisthecali-
brationtemperature.Itisnormalforthistemperature
tohave a variance of +/-10° F.
5. The same steps can be used to check the proofer
