Silo Management includes A)Silo Fumigations ● B)Silo Ventilations ● C)Silo Sealing’s
Fumigations are carried out to kill Stored Products Insects damaging food grains. More than 18 species of stored products insects in India but only few Species are causing maximum damages. Primary Insects damages the grain from inside the grain while Secondary Insects feeds on damaged grains Damages % can start from 10 to 30 % if fumigation treatment were not carried out leading to huge losses.
Fumigation Treatment carried out in air tight enclosure for a particular exposure period with gaseous chemicals which kills insects and other pest.
Scientific Method : Fumigation with Phosphine Generator which releases phosphine gas quickly after reaction between fumigant and water directly under controlled mechanism and circulation of gaseous fumigant across the silo. Conventional Method : Fumigation by application of fumigant directly to commodities, which reacts with moisture inside the enclosure and fumigant are circulated with help of J-system.
Silo Ventilations : Steel are Good Conductor of Heat. During summer outer layer of commodities became hot while inner layer stay cool. During winter outer layer of commodities became cool while inner layer stay warm. Grains are living organisms and release water vapor during respirations. Difference in temperature gradient results in condensation of moisture at top during winter and at bottom portion during summer. Moisture condensation can damages commodities, even germinations at top layers.
