  • Patent number: 7818894
    Abstract: This process embodies forcing air through grain and granular biological products using a high volume horizontal airflow from a central vertical pervious tube to one or more plenum chambers near the structure sidewall to dry or cool products. Cross-flow air movement can be supplied by either suction or pressure. This conditioning and drying method has advantages over conventional storage structures, especially where product depth is much greater than diameter. In this process, horizontal air typically moves only ? to ? of vertical distances. Horizontal airflow resistance through elongated seeds is 50-60 percent of vertical airflow. Power for horizontal airflow is typically 8-15% that of vertical airflow. Grain and seed drying costs will be 15-30% of high temperature drying. To enhance germination, storage and grain and seed quality, and to kill or exclude insect pests, ozone is applied to drying or aeration airstreams for treating stored products and storages.

    Abstract: Metal strip is coated with a coating material containing a volatilizable solvent and is heated in an enclosure for vaporizing the solvent. Condensation of vapors on the metal strip within the enclosure is avoided by providing an exhaust of sufficient capacity to withdraw all of the heated and vaporized solvent, after which it is burned, mixed with a gas having a temperature lower than its temperature, and returned into the enclosure and applied against the surface of the metal strip.

  • Patent number: 4757800
    Abstract: A food preparation apparatus including a cooking chamber having a pair of openings in two opposite facing walls thereof. A conveyor extends through the side wall openings and the chamber for conveying a food product through the chamber. First and second pairs of impingement finger ducts are provided for forming a plurality of columnated air jets and for impinging the jets against discreet points of a food product supported on the conveyor. A first one of each of said pairs of ducts is disposed above the conveyor and a second one of each of said pairs of finger ducts is disposed below the conveyor. First and second plenums, each of which has a fan respectively associated therewith, supply air to the finger ducts. One or more baffles in each of the plenums guides and streamlines the air as it flows out of the plenums and through the finger ducts. A single burner is associated with the plenums for simultaneously supplying heat energy to both plenums.

  • Patent number: 4753020
    Abstract: A dryer, especially for wood, has at least two drying chambers separated from each other by at least one partition wall, at least one fan in each of the drying chambers, and at least two connection passages for the reciprocal connection of the drying chambers. Each of the connection passages can be constricted or blocked off by blocking devices. To properly convey drying agent to where it is to be used, a fan is mounted in at least one of the drying chambers connected together by the connection passages, is associated with one connection passage, and is arranged directly adjacent to the connection passage. The blocking device includes a flap on one side only. When the flap is closed, it forms a part of the side wall of one connection passage. The flap is arranged directly in front of and in the conveying direction of the fan, such that, when it is open, it forms a deflector for the drying agent conveyed by the fan.

  • Patent number: 4640726
    Abstract: A method and apparatus for heating selected portions of an article include transport means for moving the article into a heating compartment. Shroud means, which are disposed within the heating compartment and located adjacent to limited portion of the article, direct a stream of heated gas toward a marginal portion of this article. Supply means deliver a volume rate flow of heated gas to the shroud means, and discharge means remove a volume rate of exhaust gas flow from the heating compartment. The discharge means is constructed and arranged to provide a volume rate of exhaust gas flow from the heating compartment which is greater than the volume rate of heated gas flow supplied into the shroud means.

  • Patent number: 4345386
    Abstract: Disclosed herein is an air agitation device that is positioned between two opposite sets of shelves on which the articles to be dried are placed.The device constitutes two identical crankshafts, oriented in the same direction, that rotate in synchrony with respect to axes perpendicular to the opposite surfaces of the said sets of shelves.To the crankpins of the said shafts are articulated, on opposite sides, two ventilation frames, each of which provided with a plurality of fins oriented suitably with respect to the said sets of shelves.The synchronous rotation of the crankshafts renders movable each frame, which oscillates with a harmonic motion in two inter-perpendicular directions, one of which is coincident with the longitudinal axis of the passageway existing between the sets of shelves.

  • Patent number: 4307519
    Abstract: A method of and apparatus for drying products with a gas stream passing the product to extract moisture therefrom and a contacting device producing at least one desiccant liquid layer in the vicinity of the product to be dried, which liquid layer removes moisture from the gas. The gas stream is bubbled through a substantially horizontal liquid layer or can pass between liquid film conducting elements. The desiccant liquid is continuously regenerated. By means of several partial gas streams and a contacting device having more separated liquid film modules, a counter-current type of drying is possible. The product to be dried can be heated to a predetermined temperature by the desiccant liquid through the drying gas stream.
