Stirling elevator is a large concrete grain terminal located three quarters of a mile north east of the town of Stirling, Alberta. The elevator stands 200 feet tall and is surrounded by grain fields that stretch out for hundreds of miles east, north and south. The large elevator was built between 1998-1999 with a cost of $11 million and was one of the first elevators of its kind in the area. The elevator was built with a capacity of 17,500 metric tonnes (19,300 imperial tonnes) the elevator has a total of 150,000 metric tonnes (660 million lbs) a year, this could feed over 1.3 million people a year. Eighty percent of the local farmers grain that passes through the grain elevator is shipped overseas, feeding people all over the world. The elevator may be a large building, but only requires a minimum of 6 people to maintain the elevator, due to the central computer system, making it possible to ship 5,000 tonnes in one day; loading train cars and unloading trucks both at the same time. ==Seed cleaning rooms== Located on the east side of the elevator, the seed cleaner take up three floors. In one hour, 100 tonnes of wheat can be cleaned, at such a rate it takes the cleaner only 46 hours (4 days) to clean seed for 50 train cars. The seed cleaner doesn’t just separate all foreign matter from the grain; it also sorts the foreign matter into six different groupings. The seed cleaner has six refuse bins holding wild oats, salvage wheat, mixed grains, salvage canola, cracked kernels and a small dust bin. Of the 55 tonnes of chaff sold annually, 2/3 of it is chaff and 1/3 of it is small seeds and cracked kernels. The materials separated out of the grain have a certain amount of revenue and are sold to the animal feed industry The seed cleaner is a complicated piece of equipment completing a multiplicity of tasks. The material that is removed during the seed cleaning process is placed in the bins below the seed cleaner or is sucked up to the top of the elevator through the silver tubes. The clean grain is elevated back to the top of the elevator by a small leg. At the top of the elevator it is placed onto a paddle drag that deposits it into bins 2, 4, 12, 13, 27 or bin 28. The dust separator deposits the dust it collects into the chaff holding bin on the north side of the elevator. All the silver tubes in the three photos below are part of this scavenging system; removing the dust and chaff from the different parts of the seed cleaner. Altogether, the seed cleaner stretches over a height of 70 feet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stirling Elevator」の詳細全文を読む スポンサード リンク
