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.

A plant press including a container having a cavity for receiving a plant and a plunger disposed within the cavity of the container. The plunger being translatable in a direction transverse to a longitudinal axis of the cavity and adapted to create a shearing force.

A 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. A liquid freezing agent is introduced into a container of the plant matter to fragment the undesirable matter while the desired portion rich in trichome remain intact.

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.

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 a method is for separating liquid from a material comprising a solid fraction and a liquid fraction. The apparatus has a conveyor belt for bringing the material from a receiving portion to a discharge portion. At least a portion of the conveyor belt is provided with at least one sorption means for absorbing and/or adsorbing liquid from the material while the material is carried between the receiving portion and the discharge portion.

Method for separating a polishing material, which is capable of separating and recovering cerium oxide from a used polishing material that is mainly composed of cerium oxide and a regenerated polishing material which can be obtained by the separation method. This method for separating a polishing material is characterized in that a divalent alkaline earth metal salt is added into the slurry of the used polishing material, while controlling the temperature of the slurry within the range of 10-70 DEG C., thereby causing the polishing material to aggregate under such conditions that the mother liquor has a pH of less than 10.0 as the pH is converted to one at 25 DEG C. so that the polishing material is separated from the mother liquor.

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.
