Abstract
A portable roller press that includes a base frame having a pair of opposing stanchions, a drive roller assembly having upper and lower rollers extending between and rotatably mounted to the stanchions, a pair of opposing wings that are hingedly coupled to the base frame and selectively movable between open and closed positions, and an idler roller rotatably mounted to each of the wings. The wings have recessed portions that together substantially enclose the drive roller assembly when the wings are in closed positions. Additionally, when the wings are in their closed positions, the idler rollers are contained in a void space between the upper and lower rollers. The wings can be substantially hollow and arc configured for holding and transporting items therein.
