A dual damper assembly (44) having rotatable dampers (46, 48) operated in a predetermined relative phase relationship within separate passageways (34, 36) is provided for use with food treatment systems such as a smokehouse (20) in order to control the tendency of the dampers (46, 48) to flutter and thereby alter the desired relative orientation of the dampers (46, 48). The dual damper assembly (44) includes a drive assembly (50) serving to rotate the dampers (46, 48), as well as a brake assembly (52) operably coupled with one of the dampers (46, 48). The brake assembly (52) has a rotatable disc (76) secured to a damper rod extension (58a), with an associated caliper assembly (78) including brake pads (94, 96) engaging disc (76) in order to control damper flutter.
