Patent ID: 8920099

Claim:
A method of distributing particulate material in a vessel preloaded with a particulate, the method comprising: inserting a rotational drive shaft into a vessel; positioning a leveling arm connected to the rotational drive shaft in contact with a particulate within the vessel; rotating the rotational drive shaft about an axis so that the leveling arm redistributes the particulate radially outward from the axis to lower a top of the particulate; lowering a depth of the drive shaft so that the leveling arm is in contact with the top of the particulate; and repeating the steps of rotating the rotational drive shaft about an axis so that the leveling arm redistributes the particulate radially outward from the axis to lower a top of the particulate and lowering a depth of the drive shaft so that the leveling arm is in contact with the top of the particulate until the top of the particulate is level.
