  • Patent number: 10139159
    Abstract: Infrared air float bar for use in floating and drying a continuous planar web of a material in a dryer. Direct radiated or reflected infrared electromagnetic energy from an infrared light source in a removable channel assembly accelerates drying, or evaporation of solvents, or curing of web material passing in proximity to the bar, either by infrared electromagnetic energy, or in combination with convention airflow. The infrared source is cooled by pressurized air passing through an interior portion of the removable air bar channel assembly, and the air is further conducted into fluid contact with the web in an air gap between the emitter and web to promote convective heat transfer and to contribute to the air pressure field supporting web flotation. The removable channel assembly is configured for replacement of the infrared emitter and to allow the setting of the pressurized cooling air flow to the optimum level.

    Abstract: An improvement is described for the processing of biological material in a continuous stream by the application of radiant energy taken from the wavelengths from infrared to ultraviolet, and its absorption by a feedstock in a workspace of featuring controlled turbulence created by one or more counter-rotating disk impellers. The absorbed energy and the controlled turbulence patterns create a continuous process of productive change in a feed into the reactor, with separated light and heavy product output streams flowing both inward and outward from the axis in radial counterflow. The basic mechanism of processing can be applied to a wide range of feedstocks, from the promotion of the growth of algae to make biofuel or other forms of aquaculture, to a use in the controlled combustion of organic material to make biochar.

    Abstract: A clothes dryer includes a cabinet, a drum rotatably installed within the cabinet and a heating unit that heats the drum. Because the heating unit heats the drum itself, heat generated from the heating unit is transferred to the outer surface of the drum, passes through the interior of the drum according to thermal conduction and then heats the clothes, target items to be dried, so that temperature of the entire clothes are uniformly increased to accelerate evaporation of moisture of the target items to be dried.

  • Patent number: 7098465
    Abstract: The present invention provides an electromagnetic energy spot curing method and system which integrates the UV radiation with an inert gas to disperse the gas and the radiation energy simultaneously to cure an adhesive surface on a target or work piece. The system provides a means to cure the adhesive surface during photoinitiation to expel the atmospheric oxygen which otherwise would interfere with the curing cycle.

  • Patent number: 6871418
    Abstract: This invention resides in an apparatus and related method for rapidly curing thin film sol-gel coatings, particularly such coatings adhered to low melting temperature plastic substrates, whether rigid or flexible, without deforming the substrate. The curing is achieved using IR heating lamps and dry or humid hot gas flow. This curing densities the sol-gel coating and provides desired optical and mechanical properties. The use of IR lamps and hot-gas nozzles, either singularly or in combination, produces a rapid cure by effectively heating the thin film coating layer. In this manner, a sufficiently high temperature can be attained in the film layer, to densify the sol-gel coating, but for a sufficiently short time duration to avoid melting or otherwise deforming the substrate. The sol-gel coatings can be cured two to three orders of magnitude faster than with conventional oven curing, leading to significant cost reductions and manufacturing efficiency.

  • Patent number: 6665950
    Abstract: Known gas-heated infrared radiators for infrared drying units have a radiator housing (1) that is subdivided by a gas-permeable burner plate (5) in a distribution chamber (6) for the gas-air mixture and a combustion chamber (7), the front side of which emits the radiation. The radiator is held by mixing tube (9) that is affixed to the rear side. A gas-air mixture is supplied to the distribution chamber (6) via said mixing tube (9). The mixing tube (9) has a gas nozzle (11) with a gas inlet (12) and an air inlet (17) on the end opposite the radiator housing (1). The mixing tube is affixed to a holding frame of the drying unit. In order to disassemble the infrared radiator from the infrared drying unit and to mount said radiator on said unit as rapidly as possible, the rear side of the radiator housing (1) is connected to the holding frame by releasable fixing means (20, 33-36) that can be released manually from the front side.

  • Patent number: 6523276
    Abstract: Methods and systems for extending the shelf life of produce are disclosed which provide an accelerated drying process for washed produce in order to further clean and fully crystallize a layer of solute-laden slurry that has been applied on the external surface of an item of produce (20). The drying process typical comprises three basic steps. The first step (10) is to mechanically remove excess moisture from the solute-laden slurry to form a moisture-reduced slurry layer (22) on the external surface of the item of produce (20). The second step (12) is to employ heat and/or light energy to accelerate the in-situ moisture removal process to create a protective stratum (24) on the external surface of the item of produce (20). The third step (14) is to further remove remaining moisture to permit the formation of crystalline structures (26) on the external surface of the item of produce (20).
