Abstract: A grain aeration system facilitates thorough and efficient aeration of grain within a grain bin. The system includes a grain bin having a top vent and a bottom vent. A stand is positioned within the grain bin. A duct includes a loop section supported on the stand and an extension extending from the loop section out through the bottom vent in the grain bin. The duct has a duct wall and a plurality of perforations extending through the duct wall. A blower drives air flow out of the bottom vent creating air flow into the grain bin through the top vent and into the duct wherein the blower is configured to aerate grain positioned within the grain bin.

Abstract: A grain bin aeration system has inlet ducting in communication with the hollow interior of the storage bin adjacent a perimeter of the storage bin and exhaust ducting in communication with the hollow interior of the storage bin at a central location within the storage bin. A first portion of the inlet ducting is directed to the top end of the bin so that aeration flow therethrough is directed downwardly through the material in the storage bin to the exhaust ducting. A second portion of the inlet ducting is directed to the bottom end of the bin so that aeration flow therethrough is directed upwardly through the material in the storage bin to the exhaust ducting.

Abstract: A photovoltaic receiver comprising an elongated structure bearing a plurality of photovoltaic cells. Said structure carries a plurality of finned dissipators, mounted on which are said photovoltaic cells, and ventilating means, designed to convey a flow of cooling air towards said dissipators.

Abstract: An air filter system and an air filter therefor are provided for use in a building with first and second zones separated by a wall-door system having a wall with a door therein. Weatherstripping is mounted between side and upper edges of the door and a door frame in the wall and between the lower edge of the door and the threshold region of the floor to substantially seal against air flow between the door edges and the door frame and floor when the door is closed. An air flow permitting opening is provided in the wall-door system, sized to permit a controlled amount of airflow between the first and second zones when there is a pre-determined pressure differential between said zones. An air filter is mounted in such opening.

Abstract: Aeration drying and disinfecting grain crops in bulk and pretreating seeds includes passing through a bulk of grain crops and seeds disinfecting and drying agents including an ozone and air mixture and surrounding air, subdividing the disinfecting and drying agents into a plurality of streams spaced from one another in a vertical direction, and passing the streams at different heights through levels located at corresponding heights of the bulk of grain crops and seeds transversely in a substantially horizontal direction.

Abstract: In one embodiment, the invention is directed toward a networked grain aeration control system. For example, the system can provide centralized monitoring of the aeration of a number of grain storage facilities, thereby improving the management of stored grain. The networked grain aeration control system can allow the custodian of the system to offer an aeration service. Farmers, or other individuals, cooperatives, or companies can purchase the aeration service at a cost proportionate to the amount of stored grain to be aerated and the duration of storage. In this manner, the purchaser of the aeration service can avoid relatively high fixed costs that can be associated with various aeration hardware.

Abstract: A storage floor air vent may comprise at least two vent walls positioned in substantially parallel relation to thereby define a channel; a plurality of angular baffle members, each angular baffle member composed of two segments forming an apex therebetween; the plurality of angular baffle members positioned in between the at least two vent walls in a linear arrangement, with each apex facing upward proximal the top end of each of the at least two vent walls, and each angular baffle member is positioned a distance apart from the adjacent angular baffle member to thereby define an orifice between the segment ends of adjacent angular baffle members.

Abstract: A ripening room for controlled ripening of produce includes a chamber defined by a ceiling, a floor, and a plurality of walls connecting the ceiling and the floor. The chamber is configured to receive two rows of boxed produce that are spaced apart from each other to define an interstitial volume therebetween. Each row of produce is proximate and spaced apart from one of the walls to define a side airspace therebetween. The ripening room also includes an air control system for transferring air between the side airspaces and the interstitial volume and controlling the temperature of the transferred air. The side airspaces and the interstitial volume are generally enclosed to inhibit airflow therebetween except for airflow through the air control system and through openings in the produce boxes.

Abstract: A grain bin structure for storing, conditioning, and drying grain having a floor, side walls, and a roof. The side walls are formed with a plurality of horizontal and vertical corrugations formed integrally therein and within a common circumferential plane. The vertical corrugations function as stiffeners and as vertical air conduits to dispense pressurized air about the periphery of the bin. Optionally, conduit tubes may be located within the vertically disposed corrugations to further channel air flow. These conduits are formed with an inner wall substantially flush with the interior of the horizontal corrugation, thereby maintaining a low silhouette while maximizing a cross-sectional area within each conduit to avoid undue restriction of air flow.

Abstract: Method and apparatus for storing grain in a conical pile that is aerated by means of a centrally located aeration tower. The apparatus is broken down for shipment into components which are readily erected in a site area without construction equipment which include a loading conveyor supported by a mast mounted in the site area and which is removable after filling of in site area with grain.
