This utility model discloses a bread dough fermentation device, relating to the field of bread production technology. It aims to overcome the shortcomings of existing equipment, such as uneven temperature and humidity, uncontrollable exhaust flow, poor condensate drainage, and inconvenient monitoring and operation. The device includes a cabinet with a hinged door at the front, featuring a sealing gasket and observation window. Inside the cabinet, on both sides, are air inlet chambers and exhaust chambers. An air inlet pipe is connected to the bottom of the air inlet chamber, and an exhaust pipe is connected to the top of the exhaust chamber. These chambers are separated into multiple fermentation compartments by multiple sets of partitions. Each air inlet chamber has an air inlet with a guide hood and air inlet grille corresponding to its fermentation compartment, and each exhaust chamber has an exhaust outlet with an exhaust grille corresponding to its exhaust compartment. A telescopic cylinder drives a pull rod on the top of the cabinet, which in turn drives a baffle to control the exhaust flow. Each fermentation compartment contains a support frame, temperature and humidity sensors, and drain pipes are installed at the bottom of both the air inlet and exhaust chambers. This device achieves uniform temperature and humidity distribution, precise exhaust flow adjustment, convenient condensate drainage, and is easy to observe and monitor, making it suitable for bread production.
