Fermentation - Sponge and Dough Trough System


 Stewart System's Trough System is designed to move sponge troughs from the sponge mixer to Stewart Systems Sponge and Dough Fermentation, tro room, trough room, automated, semi-automaticthe dough mixer while providing time for the dough to ferment in a conditioned atmosphere for a predetermined period of time.  The system takes the troughs from the fermentation room, and automatically loads the troughs onto the final mixer elevator (by others). Several styles can be selected, from semi-automatic to fully automatic, two-lane bun systems, and three-lane bread systems.


Multiple "knock down" units are available to keep the sponge dough growth within the confines of the troughs.


The Trough Room Enclosure consists of 4” urethane insulation tongue and groove panels in 304 stainless steel. Two personnel doors with Lexan windows with heated frame and one Lexan window in the wall section with heated frame are also included.


The supplied Conditioning System is adjustable, and typically designed for 80°F (27°C) at up to 80% Relative Humidity.
