Abstract: Controlling the production of an extract using solid-liquid extraction that improves the exchange of material during the extraction process and allows a controlled dehumidification of a raffinate with residual moisture in order to obtain additional valuable extract is described. The steps include providing a first mass in an extraction container, supplying a second mass to the first mass without spatial constraints and distributing and mixing the second mass into and with the first mass, discharging a mixture of the extract and the raffinate from the extraction container, separating the discharged mixture into the raffinate with residual moisture and extracts released from the raffinate with residual moisture, and further treating the raffinate with residual moisture at least such that the residual moisture consisting of the extract is at least partly removed from the raffinate with residual moisture by dehumidification and is supplied to the already separated extract.

Abstract: The industrial production of an extract by means of solid-liquid extraction improves the exchange of substances during extraction and allows enhanced dehumidification of a raffinate with residual moisture.
The extraction is enhanced during a first dwell time by at least partially flooding a vessel in the form of at least one flow discharged with a secondary solvent or the obtained extract, swirling and keeping in suspension the primary mixture within the vessel by supplying the secondary solvent or the obtained extract via a foot area of the vessel, and/or moving the vessel relative to the extraction container within the obtained extract. The secondary solvent or the extract circulates in the extraction container by a circulation guide incorporating the extraction container from top to bottom relative to the extraction container, and the extract freed from raffinate with residual moisture obtained by dehumidification is supplied to the separated or to be separated extract.
