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.

The present document describes a system and a process for the extraction of several products from apple peel. There are several unit operations involved including an ultrafiltration unit, concentration unit, and a three stage counter current separator centrifuge wherein water is used as the solvent. The final products that are extracted from apple peel include pectin, syrup, fibers, as well as soluble and dried retentate fractions.

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).

A biomass fractionation apparatus includes a vessel having a processing chamber, an inlet configured to receive a biomass into the processing chamber, and an outlet configured to discharge processed biomass from the chamber. A bed plate is movably positioned within the processing chamber and includes a plurality of elongated fins extending outwardly therefrom in substantially parallel spaced-apart relationship. A cylindrical rotor is rotatably secured within the processing chamber in adjacent, spaced-apart relationship with the bed plate. The rotor has a plurality of elongated blades extending radially outwardly therefrom in circumferentially spaced-apart relationship. Upon rotation of the rotor, the blades are configured to accelerate a biomass within the processing chamber against the fins of the bed plate and to cause the bed plate to pulsate against the rotor.

A method of preparing paprika red pigment with low polycyclic aromatic hydrocarbons includes (1) drying, crushing and granulating mature peppers to obtain pepper particles; (2) extracting the pepper particles with a vegetable oil in a rotocel extractor to obtain a paprika red pigment solution; (3) extracting the paprika red pigment solution with an ethanol solution in a liquid-liquid extractor to remove spicy substances; (4) running the paprika red pigment solution through a low-pressure chromatography column to remove polycyclic aromatic hydrocarbons; and (5) concentrating the paprika red pigment solution to obtain the paprika red pigment with low polycyclic aromatic hydrocarbons.

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.
