  • Mechanism for reducing emissions of dust from grain bins
    Patent number: 5893399
    Abstract: A mechanism for hindering the escape of grain dust from a grain bin, including baffle units having diagonally extending barrier members and vertically oriented baffle members. First and second sloped side walls of the bin, a cover, and a curtain confine the circulation of dust to portions of the bin remote from the baffle units to thereby hinder the escape of dust from the bin. Metering and dump units can be combined with the baffle units to allow operation of a single grain bin in both the high and low flow rate modes of operation.
