1. Why isn’t the air temperature inside my Proofer the same as the setting?
The Proofer is calibrated to keep the contents of a jar or bowl at the designated temperature setting, not the air inside. Measuring the air temperature in the proofer with a thermometer will not indicate the temperature of food in a container.
The Proofer is calibrated to keep its contents near the temperature setting, not the air inside. This is because the Proofer heats mainly by radiative heating directly from the aluminum heating plate in the base to the food containers. The air temperature inside the Proofer will become warm, but will not be the same as the temperature of food inside containers. In Proofer mode, items should always be placed on a rack.
There are two important factors that affect the temperature of food in the Proofer:
- Covering a container will raise the temperature of the food inside the container
- Adding water to the tray to create humidity will raise the temperature of food in the container.
The Proofer has been calibrated in two ways:
Humid (with water tray): 70-95 °F / 21-35 °C. Use open containers. Bread dough and preferment in open bowls, loaf, or sheet pans.
Dry (no water tray): 70 -120 °F / 21 – 49 °C. Use closed containers. Commonly used for culturing yogurt. If the Proofer is used in dry mode at 70-95 °F / 21-35 °C food temperatures may be several degrees below the setpoint.
2. Can the Proofer run for more than a few hours at a time?
Yes, the Proofer has been tested and approved for unattended operation and may be run continuously. It uses very little electricity, only about 0.03 kwh per hour when set at 75 ° F/24 °C.
3. What are the dimensions of the Folding Proofer?
Inside (open): 14.75 x 12.5 x 8” high
Outside (open): 18 x 14.5 x 10.5” high
Outside (closed): 18 x 14.5 x 3” high
Weight: 7.5 lbs.
Inside (open): 37.5 x 32 x 20 cm high
Outside (open): 46 x 37 x 27 cm high
Outside (closed): 46 x 37 x 7 cm high
Weight: 3.4 kg
4. I put bread dough in my Proofer and it doesn’t feel warm. Is it working properly?
If your Proofer is set to a cooler temp (75 °F/24 °C), it may not feel very warm to the touch even when it is working properly. To speed rising, set it to 85-90 °F / 29-32 °C. If you have been rising bread in an oven or other area that is quite warm, you may need to set the Proofer temperature higher to obtain similar results. However, the best flavors in bread are usually obtained when the dough is given enough time to rise slowly.
5. Will the Proofer work in any environment?
The Proofer has been calibrated for a room temperature of 65-70 °F. The Proofer is only designed to warm its contents, not cool. If the room temperature is above the set point, the Proofer cannot be cooler. If the ambient is very cold – lower than 55 °F / 13 °C, the temperature setting may need to be adjusted a few degrees higher to achieve the desired result.
6. Does the Proofer have a thermostat?
Yes, there is a thermostat located in the base of the Proofer. The heating element cycles on and off according to the temperature of the aluminum plate. This cycling on and off occurs within a very narrow range, making the Proofer very accurate and reliable at maintaining a steady temperature.
7. Where Can I Download an Operating Manual?
Instruction Manuals and Recipe Booklets may be downloaded on our Product Manual Support page.
8. The Proofer doesn’t seem to get hot enough at the higher end of its temperature range. Is it working properly?
The Proofer’s higher temperature range (95 – 120 °F / 35 – 49 °C) has been calibrated for use with covered containers. Lids or other coverings need to be on containers to prevent evaporation, heat loss, and contamination from the environment.
9. The Proofer seems to get too hot at the higher end of its temperature range. Is it working properly?
For the best heat circulation and most accurate culturing temperature, avoid placing jars or containers directly in the center of the Proofer. The Proofer will fit eight one quart / 1 liter mason jars without the need to place a jar in the center.
For cultures or fermentations that require extended times (>12 hours) more stable results may be achieved in the Slow Cook mode, which may be set as low as 85 °F / 30 °C. Jars or other containers of food can be placed inside a larger flat bottom container (such as a stock pot or aluminum roast pan) and covered with a lid or foil and placed directly on the heating plate. Choose Slow Cook with the Mode button and set the desired temperature.
10. Lid will not shut when folding proofer for storage.
- Make sure the folding sides are collapsed correctly and attached to the hinge at the inside back of the base.
- Ensure the small plastic cross guides are visible on the top
- Place the wire rack with feet UP so it is secured by the cross guides.
11. How long should I preheat the Proofer?
Generally preheat for 10-15 minutes
12. The walls of my Proofer came apart, how do I put them back together?
In order to prevent the walls from coming apart, we recommend always leaving them attached to the base of the Proofer in the rear hinges, even during folding and set up.
Here are some pointers for putting them back together:
- Start with the long wall that says “Warning”. Place it in the rear hinges of the base so that the writing is facing the interior of the Proofer.
- Next take one of the short walls and face the raised hinges in the middle of the wall to the outside, or exterior of the Proofer (the smooth side of the hinge should face the interior). The exposed end of the metal pin at the center hinge of this wall should be facing up and the closed end should be facing down.
- To fit the short wall into the long wall, widen the angle formed by the two walls until they are nearly a straight line, then fit the juncture together.
- Once the juncture is fastened, you can put the short wall back to a right angle with the back wall and rest it on the Proofer base.
- Attach the second short wall in the same manner as the first.
- For the last long wall, face the raised middle panel to the interior of the Proofer, then fasten it to one of the short side walls (again, it will be necessary to widen the angle between walls until it is nearly flat).
Finally, to attach the last joint, it will be necessary to form a nearly straight line with the short wall that you are attaching it to, just as you did with the other three junctures. This will be a little tricky with the other three walls already attached. To do this, leave the back wall in the hinges at the back of the base, but lift up the walls at the front of the base so that you can form a nearly flat angle with the two walls that you are trying to attach.
13. When operating the Folding Proofer, is it noisy?
No, operation of the Folding Proofer is silent.
14. How does the lid of the Proofer attach to the sides?
When the Proofer is set up, the lid rests on the walls. It does not click into place or latch. However, there is a specific way to line up the lid so that it fits properly. The two square pegs at the rear of the lid fit into the square-shaped notches at the rear wall, then the lid hinges down onto the walls.
15. What is the power consumption of the Proofer per hour?
The Proofer consumes 200 watts. When it is operating it has a duty cycle of about 30%. This means the heater is only using 200W for 30% of the time, depending on the temperature (the lower the temperature the less the time the heater has to run).
If the Proofer was ON 100% of the time it would use:
- 200 watts x 1 hour = 200 watt hour (= 0.2kwh)
But since it is only on about 30% of the time, the actual energy consumption is:
- 200 watt hour x 0.3 = 60 watt hour = 0.06 kWh / hour
In other words, it uses the same energy as a 60 watt light bulb.
16. Can household ovens with a low temperature setting be used to proof?
- Low temperature ovens do not control and hold at the single degree-by-degree temperature level.
- Low temperature ovens do not have proper humidity control The lowest temperature on a low temperature oven can not maintain the very low range of temperatures starting at 70F – 21C temperature.
- Our Proofer is calibrated by engineers to maintain the internal food temperature of the bread dough, yogurt culture, or whatever food is being made in the Proofer. A low temperature oven is set for the air inside the oven, not the ingredients a person is making. The recipes developed by Brod & Taylor have been successfully tested at the specific temperature settings indicated on each recipe.
