  • Patent number: 4549960
    Abstract: Apparatus for cleaning, aerating and fumigating grain comprises chutes having screens therein over which the grain is passed. Conduits interconnect the chutes with a blower mechanism so that the grain to be cleaned is subjected to a vacuum which causes the fine debris, trash and the like to be passed through the screen. The fine debris is entrained in a stream of air and directed exteriorly of the grain storage structure. The conduits connected to the blower assembly may be detached from the grain cleaning chutes and connected to tubes inserted into the grain to permit heated gases and moisture to be removed from the stored grain. An air entrained fumigant may also be directed through the tubes into the grain for controlling insects and the like.

  • Patent number: 4454807
    Abstract: A storage system for large quantities of flowable, granular materials, such as grain. The material is covered by flexible cover sections which are spread out on an impervious support surface and thereafter laced together to define a cover having a centrally located opening. The cover is grasped in the region of the central opening and lifted to a predetermined fill height; the perimeter of the cover being free to pull inwardly as necessary accommodating the lifting. Thereafter, the granular product is introduced into the opening until it reaches the predetermined fill height and defines a pile extending downwardly toward the support surface along a natural angle of repose. As the pile grows, it raises the cover while sweeping it upward away from the center of the pile. By this means the entire finished pile is conformably covered by the cover.

  • Patent number: 4401404
    Abstract: A storage silo, for agricultural products and the like is provided, particularly adapted for use with silos of the bottom unloader type, and which are filled through a fill pipe extending from about ground level, to the upper end of the silo. A particularly unique connection is provided between the top and bottom of the silo, for substantially eliminating a pressure differential between the top and bottom that could otherwise have adverse affects on the silage upon filling at the side. The interconnection between the top and the bottom is through the silo fill pipe, and a vent line, and additionally may be provided for including silage gas bags in common interconnection with the fill pipe. The bottom end of the fill pipe is telescopically extendable for attachment to a silage blower, and a closure for the bottom end of the fill pipe is adapted to sealingly close the fill pipe with the telescopically extendable member within the fill pipe.

  • Patent number: 4375784
    Abstract: An improved breather system for a sealed storage structure. An annular flexible diaphragm is located within the upper portion of the storage structure and the inner periphery of the diaphragm is sealed to a central inlet feed tube, while the outer periphery is sealed to an impervious platform that is mounted on the wall of the structure beneath the roof. A manhole is provided in the roof for entry onto the platform by workmen in order to repair or replace the diaphragm. The diaphragm and platform separate the storage structure into a lower storage chamber and an upper chamber which is exposed to the atmosphere. The diaphragm will move up and down within the structure in accordance with the pressure differential between the chambers. The diaphragm has a substantially greater surface area than the cross section area of the storage structure, so there is substantial travel between its uppermost and lowermost positions to thereby greatly increase the breathing capacity over conventional breather systems.

  • Patent number: 4321866
    Abstract: This invention is an improved breather bag apparatus used with a sealed storage bin such as a silo allowing for expansion and contraction of the air within the sealed structure due to changes in the air temperature in the sealed storage bin. As a material with a high moisture content is normally being stored, the connector pipe between the improved breather bag structure is inclined back into the storage bin for any condensed fluid to flow back into the storage bin to keep the stored material moist. This improved breather bag apparatus is mountable on the sidewall of an existing silo within a protector shell member and having a bag member that is readily observable from adjacent the silo to ascertain whether such is operating properly and having a drain valve to release fluid from the bag member. The protector shell member is provided with a bottom wall with an access door to allow one entrance to the drain valve for operation thereof.

  • Patent number: 4223044
    Abstract: A bridge of particulate and ground food, feed and inorganic substances, such as soybean meal, corn meal, flour, cement and the like in a storage vessel is broken by reducing the internal pressure of the vessel and introducing inert gas under pressure of from atmosphere to up to 10 kg/cm.sup.2 to impart impact for breaking the bridge of the particulate and ground substances. After discharge of the particulate and ground substances from the storage vessel, the matter sticking to the internal walls of the vessel can be removed by again reducing pressure and giving impact of introduced atmosphere or pressurized gas. Further, the internal pressure of the closed storage vessel is reduced prior to injecting fumigant gas and thereafter by introducing inert gas the internal pressure is brought to normal pressure to improve fumigation of the substances.
