The grain mass is being reduced until the dial indicator hand of the differential pressure gauge meets the corresponding mark on the dial.

When the ventilation is turned on if the dial indicator hand is below the mark, then the grain mass in the silo should be reduced. This method requires a differential pressure gauge to be installed outside the silo its dial shall be marked so that to indicate the minimum air pressure drop for different grain crops. We suggest controlling the grain mass thickness in the silo by the air pressure drop inside the grain mass.

With a thinner layer thickness, a larger volume of air is supplied. The supply of the required air volume does not depend on the silo design and equipment or the stored grain crop thus, we suggest ensuring this effect by changing the thickness of the grain layer. The maximum effect of active ventilation on the grain mass is achieved at the standard air volume not less than 10 m 3/ht. The second installation for ventilation the over-grain space is to remove condensate formed during the grain storage and settled on silo structures. This installation is used for cooling the grain to increase its shelf life, to prevent or eliminate self-heating in the grain mass. Active ventilation affects the grain mass with upward flow of atmospheric air. 1 IntroductionĪ regular flat bottom steel silo intended for storing grain is provided with two installations impacting the air space inside the silo: active ventilation of the grain mass and over-grain space ventilation under the silo roof.

The probable periods of condensate in the space under the silo roof depending on the temperature difference inside and outside the silo have been determined. The study was aimed at identifying the possibility of condensed moisture appearing under the silo roof. * Corresponding author: study was conducted concerning effects of temperature and relative air humidity during long-term storage of wheat grain in a steel silo.

Soldan said Ontario’s labour ministry had been notified.Įditor’s note: An earlier version of this story included a link that incorrectly identified the farm’s owner. Huron and Area Search and Rescue was also on scene, and Soldan said the Joint Rescue Co-ordination Centre in Trenton was contacted in case air support was needed to remove the man from the silo. Responding to the scene were the Exeter, Dashwood and Zurich fire stations, as well as Huron OPP and paramedics. Becker said breathing was never a problem for the man, who was conscious throughout his ordeal. The grain had to be emptied slowly from the bottom of the silo because releasing it quickly could have been dangerous to the man trapped inside, the chief noted.

Just a lengthy, slow process, but that’s the way we had to do it,” Becker said, adding the entire effort took roughly two hours. He was still flown to hospital in London as a precaution. Soldan said the man experienced some leg compression while trapped but suffered no major injuries. He was met with applause as he exited the bottom of the silo and was able to walk to a stretcher without assistance.Ī man was rescued after falling into a 14-metre-tall grain silo between Dashwood and Zurich on Monday June 19, 2023. He was eventually able to safely slide out a bottom panel of the silo at about 11:15 a.m., which had been opened to slowly release the grain. Using the fire department’s ladder truck to get to the top of the silo, Becker said firefighters were in constant communication with the trapped man. South Huron fire Chief Jeremy Becker said people at the scene were making attempts to remove the man from the silo and had him secured with a rope before firefighters arrived and took over.
