Process for extracting of liquid from a residual substance

A process for forming a juice product of a selected quality by the extraction of liquid from residues of dregs, macromolecules and colloidally dissolved particles separated from a filtered residual substance, including residues resulting from the extraction of juices from agricultural products comprising fruit, grain, berries and vegetables, the steps of subjecting an agricultural product to a first extraction to obtain a raw juice and an at least partially pressed out pomace, subjecting the juice to a fining or clarification operation to form a clear juice and a retentate consisting of a residue of dregs, macromolecules and colloidally dissolved particles, mixing the retentate with the at least partially pressed out pomace in a further processing step subsequent to and separate from the first extraction step to form a processed pomace so that the first extraction of juice from the agricultural product remains undisturbed, and subjecting the processed pomace to a second juice extraction separate from the first extraction to obtain additional raw juice.
