摘要:
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.

A method and apparatus for removing a bakery carrier screen, which is carrying a bakery product and traveling on a moving conveyor system, from underneath the carried bakery product and transferring the bakery product to an exit conveyor during substantially continuous forward motion of the bakery product is provided. The carrier screen upon which the bakery product is placed has a generally rectangular and planar surface with a plurality of parallel longitudinal slots extending from the leading edge to the trailing edge of the screen. A product entrance conveyor is provided which has a plurality of substantially parallel and spaced apart endless conveyor belts terminating in generally aligned pulleys, and a conventional full width endless conveyor for removing the products arranged at the forward end of the entrance conveyor belts. The spacing and arrangement of the entrance conveyor belts is such that when the carrier screen with the carried product reaches the forward end of the entrance conveyor, the carrier screen interdigitates around the ends of the entrance conveyor and downwardly, between the entrance and the exit conveyor, so that the bakery product is left still supported directly by the entrance conveyor belts. The product is then transported from the entrance conveyor onto the exit conveyor without the carrier screen.
摘要:
A metering unit for dough and related foodstuffs having a dough feeder unit, support structure, dough hopper, effluent housing, drive motor and centerless helix, with the effluent housing including an inlet, center and outlet section. The centerless helix is disposed within the effluent housing, and is rotatably coupled to the drive motor. Dough is fed into an aperture in the input section of the effluent housing, and upon rotation of the centerless helix, is discharged from the outlet section of the effluent housing. The internal flowpath of the effluent housing can include a separate discharge liner to prevent the centerless helix from contacting the flowpath wall. Additional control mechanisms can be included to limit motor power output and protect the system in event of an overpressure condition. The system is portable, and can be coupled to a conventional conveyor system to create an integrated approach to dough metering and transport.

In a method and apparatus for automatic handling of bread pans adapted for use in a baking process, individual empty pans are received and stacked at a first station and automatically moved to a predetermined storage station. When individual pans are required, the stacked pans are selectively removed from the storage station and transported to an automatically operable unstacking device. The method and apparatus includes a control system for detecting a demand for individual pans which operates the unstacking device and distributes individual pans in response to the demand.
摘要:
A conveyor system including a monorail drive having vertically extending brackets which support a continuous product support surface. The product support surface includes separately supported grid surfaces which interleave with the next adjacent grid thereby to facilitate turning around a radius while maintaining a continuous product support surface.

The specification discloses a chain link assembly and chain incorporating said assembly, the chain being especially adapted for use in enclosed track-type conveyors. The assembly includes a pair of identical, elongated link members fitted together and mating with one another. Each link member has chain pin or fastener receiving openings at either end and a bridge member adapted to engage, support, and space the opposite link member. One end of each link member at the same end of the assembly includes a curved surface with elongated chain pin receiving openings to allow articulation of the assembly at that one end. The opposite ends are planar.
