A liquid extractor may include an extraction chamber containing a bed deck configured to support a solid material as the solid material is conveyed through the extraction chamber. To introduce solvent into the solid material being processed, the extractor may include a solvent injection orifice extending through the bed deck and a solvent injector. The solvent injector can receive solvent from a source and cause the solvent to rotate within the solvent injector before discharging the solvent through an outlet in fluid communication with the solvent injection orifice. The rotational flow motion imparted by the injector can create a vortex that functions to scout out any particles that may be present in the injector.

A horizontal axis rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. The process physically separates resin rich beads at the trichome gland head from extraneous plant matter by one or move separation sieves. The sieves are provided in or as a casing over a rigid frame member. The sieves are mesh fabric bags or screen that are easily opened and replenished in a batch operating mode, and are removable from the frame for cleaning and maintenance. Other aspects of the invention include processes that improve process efficiency and speed, and yield products of superior quality.

Devices and methods for the high-pressure treatment of bulk material by extraction and/or impregnation. The bulk material is arranged in the interior volume of a pressure vessel device and is treated at a high pressure while sealed off from the surroundings. The high-pressure treatment is performed batchwise in a closed system in the pressure vessel device in a pressure-tight fashion. The bulk material is fed batchwise to the interior volume with the pressure vessel device closed and being arranged on at least one treatment level and, after the high-pressure treatment has occurred, being discharged batchwise from the interior volume with the pressure vessel device closed. The invention furthermore relates to the use of a supporting tray module with at least one treatment level for the high-pressure treatment in a closed system.

Methods and systems are provided for recovering an organic solvent from a waste sludge generated during formation of a polyarylene sulfide. Methods include combining the waste sludge with a liquid extractant that extracts the organic solvent into a homogeneous liquid phase. Upon a temperature change, the homogeneous liquid phase can separate into an organic solvent-rich liquid phase and a liquid extractant-rich liquid phase. The two liquid phases can be separated and further processed if desired to further purify the recovered organic solvent. Methods can also include forming the polyarylene sulfide by a polymerization process and thereafter purifying a slurry of the polyarylene sulfide. A liquid washing product is formed as a result of the purification process, which can be subjected to a distillation process that forms an organic solvent-rich stream and the waste sludge.

Device (V) for obtaining a wort (WO) from a mash (MA) in the beer brewing or beverage industry, at least comprising a receiving unit (AG) for receiving the mash (MA); at least one separating device (T; T1, T2) each having a surface (FA; FA1, FA2); wherein the surface (FA) has a multiplicity of openings (OP); wherein the device (V) is preferably suitable for separating the mash (MA) into the wort (WO) and a residual mash (RM) by means of the surface (FA) of the separating device (T); wherein the surface (FA; FA1, FA2) or a part thereof can be brought into contact with the mash (MA), if the mash (MA) is present in the receiving unit (AG) for separation into the wort (WO) and the residual mash (RM); and wherein, during the operation of the device (V), the surface (FA) is arranged such that it is moved or can be moved or can be rotated relative to the mash (MA), the residual mash (RM) and/or the receiving unit (AG).

An apparatus and method of high pressure treatment of bulk material by extraction and/or impregnation may involve treating bulk material in an internal volume of a pressure vessel apparatus at a high pressure level in a range from 40 to 1000 bar under isolation from the environment. The high pressure treatment may be performed charge-wise in a closed system in the pressure vessel apparatus in that the bulk material is supplied charge-wise to the internal volume with the pressure vessel apparatus closed and is positioned in at least one treatment plane. Upon completion of the high pressure treatment, the bulk material is discharged charge-wise from the internal volume with the pressure vessel apparatus closed. This also gives advantages in terms of handling, especially also with regard to material flow, and with regard to operational reliability.

An apparatus and method for high pressure treatment of bulk material by extraction and/or impregnation may involve high pressure treating bulk material in a high pressure treatment volume of a pressure vessel apparatus at a high pressure level, especially high pressure in the range from 40 to 1000 bar. The method comprises at least the three following step sequences that are each controllable individually: pressurization, high pressure treatment, and depressurization. The high pressure treatment is performed in a continuous manner in the high pressure treatment volume. The high pressure treatment volume or the entire pressure vessel apparatus is in a fixed arrangement during the high pressure treatment. The continuity of the high pressure treatment is ensured solely by means of the high pressure treatment volume. This especially enables engineering optimization of high pressure treatment processes, for example extraction.

A device, system and method are for treating a suspension, containing plant constituents, in particular separating a liquid or a solid therefrom, in the field of production of food, pharmaceutical and luxury products, and to corresponding uses. The device for continuously or discontinuously treating a suspension, in particular for separating a liquid or liquid phase or a solid or a residual phase from the suspension includes: a receiving unit for receiving the suspension and at least one separating device having a surface having openings. The surface can be brought into contact with the suspension, if the suspension is present in the receiving unit for separation into the liquid phase and the solid phase. During the operation of the device, the surface is arranged such that it is moved or can be moved or can be rotated relative to the suspension, the solid phase and/or the receiving unit.
