Abstract: The invention relates to a method for impregnating a support matrix with solid and/or liquid compounds using a compressed gas or a compressed mixture of gases at densities ranging from 0.15 to 1.3 kg/l and at least two unsymmetrical pressure changes (pulsations). The method is further characterized in that both a multitude of impregnating substances such as biologically active compounds, technical materials or metal-organic compounds, as well as support matrices of biological origin and organic or inorganic substances can be used that have large inner surfaces and/or inner surfaces that are difficult to access.

Abstract: Process for the extraction of substances from at least one silane-modified oxidic or silicatic filler, wherein at least one gas compressed by means of pressure and/or temperature is employed as the extraction agent and the compressed gas is led in the radial direction through the filler in the pressure container and/or the substances extracted from the silane-modified filler are removed from the compressed gas with a suitable sorbent. A device for carrying out the process is furthermore described, wherein this comprises at least one pressure container having at least one internal container, sieve or insert for accommodation of the fillers which is permeable to gas and at least one gas feed and gas removal in the bulk bed of filler, and has a radially designed gas feed or gas removal from the bulk bed of filler.

Abstract: The invention relates to a method of extracting natural materials with carbon dioxide, in which the materials are used in the form of pellets of a diameter of 1.5 to 4.0 mm and a length of 1.5 to 10 mm, and of a bulk density of 0.4 to 0.6 kg/l, this method being highly suitable for the carbon dioxide extraction of hop constituents, so that the commonly practiced second grinding becomes unnecessary.

Abstract: The present invention provides a matrix for the production of pellets from powdered, granular, fibrous or pre-compressed loose material, said matrix having a plurality of pressure canals passing therethrough through which the loose material is forced and having cutting means which divides up the pressed material emerging from the pressure canals into pellets of predetermined length, wherein, on the exit side of the matrix, there are present flanges running between the pressure canals with a constant distance from one another, between which flanges sections of the cutting means extend up to the exit ends of the pressure canals.

Abstract: The present invention provides a process for the separation of materials obtained by means of high pressure extraction from an extraction agent, wherein extraction agent loaded with extracted material is passed from below into a separator comprising a head (2), a bottom (3), a runback pipe (4) and a heat exchanger (1) in the form of one or more pipes and extract recycled in a forced circulation via the head (2) and the runback pipe (4) to the bottom (3) and there either discharged and/or returned to the heat exchanger (1), the extraction agent evaporated in the heat exchanger being removed via a filter (11) on the head (2).
