Abstract: A two roll press machine for removing moisture from particulate organic material includes a stationary powered roll and a powered positionable roll journalled within a carriage slidably entrained on a machine base. A hydraulic cylinder biases the movable roll into heavily biased, linear contact with the stationary roll. Barrier plates in place above the rolls laterally confine expelled fluid. Collector boxes proximate the extremes of the roll nip remove the fluid. A spreader mechanism is supported on the machine base for distribution of material across the rolls. The machine base permits stacking of the machines for sequential pressing of material.
