Abstract
A damper control is employed in the exhaust duct of a bakery oven to maintain constant air mass flow through the duct during a baking cycle to ensure even baking conditions. The damper control can include a pitot tube from which velocity pressure can be derived, and a pneumatic or electronic control loop to move an exhaust damper in the exhaust duct as necessary to keep the velocity pressure constant.
