For over 30 years, the Design III StirAtor has been the most dependable stirator system. Though among the lowest in capacity, the Design III can turn a grain bin into a drying system at a minimum investment. A high temperature, above 10 degree rise, bin dryer has to have a way to dry all the grain to the same moisture. Just running a fan & heater on a bin full of grain will result in 5% grain at the bottom with no moisture removed on the top. GSI’s StirAtor ensures that all the grain is the same moisture, with no wet tank required; all you need is a fan & heater and an auger to fill the bin.
Unlike other stirators, the Design III StirAtor has a unique drive that changes the path of the augers every revolution around the bin. The pattern puts the augers in the outer 1/3 of the bin where 50% of the grain is more than in the center so all the grain gets uniformly stirred. On every Design III you can lock the augers in the outside position at the end of the year to thoroughly stir and cool the grain at the bin wall to minimize issues during the storage period.
You can customize the StirAtor to meet your needs by adding various options. Including a Stir-Guard ensures the stirring augers do not stall, hard surfaced augers for longer life, or graduated pitch augers with more flighting at the bottom for easier start-ups and better stirring action in difficult grains.
