Abstract: Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described.

Abstract: A weighing and labeling system has an electronic scale, label printer, and at least one controller. The controller stores information about incoming food packages and drives the printer to produce labels based on the stored information and the weight of the food packages. The labels are transferred to the food packages. Some elements of the system are located in sealable cabinets, and further, some of the elements are mounted on the interior surface on doors hinged to the sealable cabinets. This is advantageous in food production environments requiring frequent cleaning of equipment with sprayed water. In some embodiments the sealable cabinets are positioned on vertical masts and rotatable on the masts.

Abstract: A flow control device has a duct section with a plurality of damper blocking elements, each having a major plane. The damper blocking elements are pivotably connected to the duct section and movable in a range that is limited to ensure that, when the duct section is mounted in a preferred orientation, the damper blocking element major planes always form an angle of at least 45 degrees from the horizontal throughout the range. The range is such that the plurality of damper blocking elements can selectively close and open the duct. The blocking elements can completely close the duct, for example, to block natural convection.

Abstract: Systems, devices and methods provide energy recover, modular systems to build and revise commercial kitchen services, closed circuit exhaust, and high efficiency capture and containment of fumes from cooking processes.

Abstract: Exhaust capture and containment are enhanced by means of automatic or manual side skirts, a sensitive breach detector based on interference effects, a combination of vertical and horizontal edge jets, and/or corner jets that are directed to the center diagonally from corners. Associated control functions are described.

Abstract: An exhaust device for convection or combi ovens captures exhaust from opening side-opening oven doors with minimal energy waste.

Abstract: An exhaust apparatus for a conveyor oven includes a first hood linked to a duct at a first end of the duct and connected to a frame configured for mounting on the conveyor oven such that the first hood is positioned directly over a conveyor tray of the conveyor oven. The first hood has at least one grease filter and a recess defined at least in part by an interior wall, the hood interior wall having a first side, a second side opposite to the first side, a bottom edge, a top edge, and opposing side edges. The hood interior wall bottom edge is aligned with a top of the conveyor oven and is aligned directly over an access located in the bounding external surface of the conveyor oven when the first hood is mounted on the conveyor oven.

Abstract: An exhaust hood includes a top wall extending in a horizontal direction, a convexly curved front wall extending in a vertical direction from the top wall. The hood also includes a filter support plate that holds a grease filter under the top wall and horizontally spaced from the front wall. The support plate is angled such that a bottom edge of the plate is farther in the horizontal direction from the front wall than a top edge of the plate proximal to the top wall. Surfaces of the top wall, the front wall, the filter support panel, and of a baffle under the support plate bound a chamber through which fumes flow to the grease filter. A free end of the front wall can be closer to the top wall than a portion of the front wall between the first end and the free end of the front wall.

Abstract: A low profile exhaust hood has a high inlet and a high aspect ratio of horizontal to vertical. A sloping wall of the recess guides hot plumes upwardly to the inlet. The inlet is sized to provide an exhaust face velocity that is at least as high as a highest possible plume velocity for a 400 F oven. The inlet is located high and forwardly to cause a suction zone to be generated near the forward edge of the hood to aid in capturing plumes tending to escape which are remote from the sloping wall.
