Abstract: A process and apparatus for maintaining uniform density of granular-type insulation which is subject to packing. Short gas blasts, from strategically disposed jets fluff the insulation when packing occurs to restore original density. The gas blasts can be triggered by automatic-type control devices which indicate a packed condition.
