Abstract
A proofer includes an enclosure defining a chamber. An air circulation system includes a passageway having an air inlet and an air outlet connected to the chamber. A first fan pulls air into the air inlet from the chamber, and expels air from the outlet into the chamber. A fluid reservoir is positioned adjacent the air circulation system, such that air contacting fluid in the reservoir upon actuation of the first fan is humidified. A heating element heats fluid in the fluid reservoir, and a second fan flows air over at least a portion of the reservoir outside the chamber and cools fluid in the reservoir. A controller selectively actuates the heating element and the second fan based upon the temperature and/or humidity in the chamber to control the temperature of the fluid in the reservoir and thereby reduce fluctuations in temperature and humidity within the chamber.
