A foam drying apparatus is provided. The apparatus is configured to pass air, and in some cases heated and/or dried air, through a quantity of foam. This air passing through the foam absorbs or otherwise carries moisture out of the foam, drying it. The apparatus may utilize a pressure differential on opposite sides of the foam, causing air on the higher pressure side to pass through the foam. Typical applications may include the drying of foam assemblies which use water based adhesives to accelerate drying of the adhesive and/or removal of water from the foam assembly, and packaging of the foam assembly.

A drying device contains an upper drying head and a lower drying head. The upper drying head is arranged above a transport plane, in which objects to be dried can be transported in a transport direction through the drying device. The lower drying head is arranged below the transport plane. The upper drying head and the lower drying head contain in each case at least one air outlet slot and the longitudinal directions of the air outlet slots essentially extending parallel to the transport plane and transversely to the transport direction, and in which slot planes, in which the air outlet slots extend, intersect the transport plane at angles which are greater than 0° and less than 90°.

An air knife for discharging a stream of gas onto a sheet of material. The air knife includes a main body including an inlet portion and an outlet portion, and a plurality of inlet ports. The inlet portion defines a plenum. The outlet portion defines an exit orifice in fluid communication with the plenum. The inlet ports project from the inlet portion and each inlet port comprises a passageway in fluid communication with the plenum. In some embodiments, the inlet ports project from a rear, or trailing, wall of the main body. In other embodiments, the outlet portion terminates at an exit face in which the exit orifice is formed, with a tip region of the outlet portion forming a taper angle of not more than 90 degrees in extension to the exit face.

Disclosed herein is a device for multianalyte detection, and systems and methods for drying reagents in wells in the device in a manner that preserves functional performance. Specifically, disclosed is a system for drying reagents in the wells of a multiwell plate. The multiwell plate is sprayed with air from nozzles positioned above the multiwell plate. Air is exhausted evenly below the multiwell plate. This allows for the rapid, consistent drying of large volumes of liquid in the well of a multiwell plate.

Material processing apparatus (20) includes a housing (22) with a plurality of vertically stacked inverting pan conveyors (42, 44) therein. Each conveyor (42, 44) includes a plurality of conveyor pans (50) traveling between and around aligned front and rear sprocket pairs (90, 92) to define upper and lower conveyor runs (52, 54). Each pan (50) has a perforated base plate (56) presenting a pair of opposed material-supporting surfaces (58, 60). As the pans (50) traverse the sprocket pairs (90, 92), they are inverted, and material (110) carried by the upper run pans (50) is transferred to the lower run pans (50) by passage of the material around and/or between the sprocket pair (90).
