摘要:
The invention relates to a method for the extraction of contained materials, in particular contaminants, from liquids or solid dispersions, by means of the use of compressed extraction agents, such as for example supercritical or liquid carbon dioxide, whereby the liquid or dispersion is introduced into a pressure-resistant vessel in the form of a thin film and the surface of the thin film treated with the extraction agent, in particular carbon dioxide. The surface of the thin film is continuously regenerated over at least a part of the layer thickness of the thin film as a result of the mechanical treatment of the liquid or dispersion.

The invention relates to a locking device for fixing a lid (1) to the opening (8) of a pressure vessel, comprising at least two locking segments (5) that can be moved crosswise relative to the axis of the opening (8), said locking segments having projecting elements (6) and groove-shaped recesses in their periphery that in closed position cooperate with recesses (7) or projecting elements in the edge of the opening, wherein the displacement drive mechanism (4) of the segments (5) is hinged to the segments (5) and at least one site of action arranged on the lid (1) or on a component (3) that is connected to the lid (1). According to the invention, the segments (5) arranged in peripheral direction of the lid (1) are supported in an articulated manner on the lid (1) by means of a pivoting arm (16) that is separate from the displacement drive mechanism (4).

摘要:
In a method for enriching valuable substances, in particular phytochemicals, such as polyphenols, colorants, antioxidants and similar, from a liquid raw material, such as lipids, fermentation broths or solvent extracts, the raw material is mixed in a mixing device (5) with a compressed extraction agent, in particular CO 2 , from a storage container (1), whereupon the mixture is fed to a pre-concentrate separator (13) and the more highly soluble components in the extraction agent are separated from the undissolved components. The charged extraction agent is extracted from the pre-concentrate separator (13) and the undissolved components remain as a pre-concentrate, wherein the charged extraction agent is guided via a separation system, in which the dissolved substances are separated from the charged extraction agent, wherein the purified extraction agent is returned to the storage container (1).
摘要:
In a process for extracting lipids from aqueous suspensions of biomass, especially from digested algal suspensions, using water-immiscible solvents, the algal suspension with an algal content of 50% by weight is supplied continuously to a thin-film extruder and contacted as a thin film with the solvent present in the liquid or supercritical state in the thin-film extractor, and then the solvent is recovered by expanding the solution composed of solvent and lipids, and the extracted lipids are removed.
