  • Patent number: 7024796
    Abstract: This invention discloses systems and methods for conversion of manure to novel fertilizer and/or soil builder products useful as input for organic farming operations. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel. The dryer vessel receives the manure for contact with the turbine exhaust gases to convert the manure to a dry material, which is passed to the processing unit where it is formed into granules, pellets or other desired form for the final dry fertilizer product. The method comprises drying, heating and converting the manure to form novel self binding fertilizer and soil builder type products for organic farming and other uses.

  • Patent number: 7018201
    Abstract: A dehydration tunnel for fruits, vegetables, and other products reduces the vulnerability of the products to damage from carmelization and case hardening by dividing a row of product vessels into two segments, passing heated air simultaneously over both segments but in opposite directions, and advancing the row of vessels unidirectionally through the tunnel. Each vessel is thus exposed to a stream of heated air traversing the vessel in one direction, followed by a separate stream of heated air traversing the vessel in the opposite direction. This allows the tunnel to be operated at moderate temperatures and reduces the harmful temperature cycling of each vessel that is typical of tunnel dryers of the prior art.

    Abstract: A mixture of lower alcohols whose mean molecular weight is 46 or less is supplied onto a surface of a semiconductor wafer cleansed with water. With this supply, the amount of alcohols left on the semiconductor wafer which has been dried can be suppressed to 2ng/cm2 or less, and thus a gate oxide film formed on the semiconductor wafer is prevented from deterioration. As a result, a high yield of semiconductor products can be realized.

  • Patent number: 6311411
    Abstract: An vertical dryer (10) is provided having a plurality of individual dryer decks (12-18) including alternating fan and heater decks (14, 16), an air circulation assembly (11), and an upright, common plenum chamber (26) in communication with the decks (12-18). The assembly (11) is operable to create a continuous drying air stream which passes upwardly in countercurrent flow relationship to product on the decks (12-18). Also, the assembly (11) serves to pass the drying air stream into, through and out of the plenum (26) at the level of each heater deck (16); in the plenum (26), the air stream velocity is decreased, causing particulate fines to fall out of the stream for collection. The use of the common plenum (26) also allows independent control of the decks (12-18) in terms of air flows therethrough and recirculation characteristics.
