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 by-product is expelled from the extraction chamber by moving the work station and discharging the dry product in accordance therewith.
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 apparatus for producing and collecting a liquid extract and a dry by-product from a mash of material, comprising an extraction chamber having an inner cross-sectional dimension and at least one open end, the chamber including a material inlet opening located in proximity to the open end for filling the chamber with the mash and a liquid outlet opening for collecting the liquid extract, a first plunger movable in the chamber, a first fluid motor coupled to the first plunger for moving the first plunger within the chamber, the first plunger including a head having a thickness which is greater than the material inlet opening to close the inlet opening when the first plunger is moved in proximity to the open end of the chamber, a second plunger movable relative to the open end of the chamber, a second fluid motor coupled to the second plunger for moving the second plunger into the chamber to close the second end and the material inlet opening, the second plunger including a first section having an outer cross-sectional dimension greater than the inner cross-sectional dimension of the chamber and a second section having an outer cross-sectional dimension generally equal to the inner cross-sectional dimension of the chamber to allow movement in the chamber, movement of the second section in the chamber being limited by engagement of the first section with the open end, the second section of the second head having a length sufficient to close the material inlet opening when the second section is moved to its limit in the chamber, movement of the first and second plungers in the chamber closing the material inlet opening and compressing the mash therebetween to extract the liquid and form a pressed dry by-product, a by-product outlet opening for collecting the dry by-product, and means for expelling the by-product from the chamber.
