Home-Built Low-Cost Grain Vacuum
 ✖  |
Fifteen years ago, Roger Datisman of Sherrill, Iowa, designed and built this low-cost grain vacuum using an old silage blower and his 200-bu. grain wagon (Vol. 7, No. 6). His "reversed" silo blower sucks air out of the sealed-up wagon, pulling grain up the 8-in. flexible metal tubing used as a vacuum hose. He converted the wagon into a giant vacuum chamber by installing a layer of perforated flooring across the top and built a 1-ft. high plywood extension above the flooring. He then sealed the wagon shut with a sheet of plywood across the top, cutting an 8-in. dia. hole in one end of the plywood sheet and another the same size in the side of the wagon below the perforated floor.
