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.
An apparatus for producing and collecting a liquid extract and a dry by-product from a mash of material, comprising:
An apparatus for producing and collecting a liquid extract and a dry by-product from a mash of material, comprising an extraction chamber having an open end for expelling the dry by-product, the chamber including a material inlet opening in proximity to the open end, and a liquid outlet opening for collecting the liquid extract, a gate movable between a first position where the open end is open and a second position where the open end and the filler opening are closed, a plunger axially movable within the chamber for compressing the mash when the gate is in its second position and expelling the dry by-product when the gate is moved to its first position, control means for moving the gate and plunger, agitating means for agitating the mash within the chamber, coupling means for rotatably coupling the agitating means to the plunger such that the plunger and agitating means are moved coincidentally, and drive means for rotating the agitating means with respect to the plunger.
