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 and a mechanism for compressing the mash of fibrous material within the extraction chamber to extract the liquid and form a pressed dry product therefrom. The extraction chamber includes a material inlet opening for filling the chamber with the mash, a liquid outlet opening for collecting the liquid extract, and a by-product outlet opening for collecting the dry by-product. The compressing mechanism expells the dry by-product from the extraction chamber once the liquid has been extracted from the mash. The mash is compressed within a movable work station, and the dry-product is expelled from the extraction chamber by moving the work station and discharging the dry product in accordance therewith.
A method for producing and collecting a liquid extract and a dry by-product from a mash, comprising the steps of moving a first plunger in a first direction to close an open end of an extraction chamber, moving a second plunger in the first direction within the chamber to open a filler opening in the chamber in proximity to the open end to allow the chamber to be filled with mash, further moving the first plunger in the first direction in the chamber to close the filler opening, moving the second plunger in a second direction opposite to the first direction in the chamber to compress the mash between the first and second plungers thereby to extract the liquid and form a pressed dry by-product therefrom, collecting the liquid extract, expelling the dry by-product from the extraction chamber by moving the first and second plungers in the second direction to open the open end and discharge the dry by-product, and collecting the dry by-product.
