Outside Breather Bags For Harvestore Silos
"More Store" outside breather bags for sealed silos that FARM SHOW first told you about nearly five years ago are "going strong" according to the inventor, Andy Thompson, Courtland, Kan.
Thompson says his outside Breather Bag allows you to remove the existing interior bag, which takes up valuable silo storage space. He notes that a 27-ft. dia. silo loses 2,300 bu. of capacity due to the inside breather bag.
Thompson says other disadvantages, of inside breather bags are that they force you to climb the silo to check them, necessitate going into the silo to tie them, and they put pressure on the inside seals.
"With More Store, the æbreathing' is done by a breather bag mounted in a fiberglass canister attached to the side of the silo. This gives you full silo capacity and keeps birds and rodents from damaging the bag. The canister has a see-through bottom so you can easily tell if the bag is working," Thompson points out.
Made of heavy-duty plastic, the bag still functions the same as if it was inside the silo, expanding as air inside the silo warms and contracting as air cools. Thompson notes the bags can withstand temperatures as low as -30º. A 2-in. dia. pvc pipe runs from the top of the bag to the silo cap. An additional benefit, is that you can hook as many as three silos into one More Store.
There are three models to choose from to match your silo set-up. Model 200 for 20 by 60 structures for example sells for about $3,000.
