ABSTRACT:
A completely sealed silo structure for animal feed which while excluding atmospheric oxygen will permit access by the operator for purposes of maintenance and repair. The sealed silo has the usual pressure compensation means but, instead of the common bottom unloading mechanism, has a top unloader which conveys feed through a sealed chute to the bottom. Sealed access doors are provided for both the feed chute and the service chute as well as between the two chutes.
