ABSTRACT:
An apparatus for producing and collecting a liquid extract and a pressed dry by-product from a mash of fibrous material includes an extraction chamber, a movable piston for compressing the mash of fibrous material, an agitator coupled to the piston so that the agitator moves coincident with the piston, and a drive mechanism for rotating the agitator to mix the mash. The extraction chamber includes an open end for expelling the by-product, a material inlet opening in proximity to the open end for filling the chamber with the mash, and a liquid outlet opening for collecting the liquid extract. A gate closes the open end to form a work station within the extraction chamber which is filled with the mash. The mash is agitated and compressed within the work station to extract the liquid and form a pressed dry product therefrom, and the gate is removed to open the end of the chamber to allow the dry product to be expelled.
