At least one storage container is used to provide therein a suspension of a biogenic starting material and at least one further storage container is used to provide a solvent therein. A cell extract is produced in a cell lysis unit and a gas is led through the cell extract in an extraction stage and the gas loaded with the valuable cellular materials is separated from the valuable cellular materials in a separation stage while reducing the pressure. The biogenic starting material suspension is brought to a pressure of 100 to 2500 bar by means of a device for increasing the pressure. The solvent is brought to a pressure of 100 to 2500 bar by means of a device for increasing the pressure. The solvent and the suspension are combined in a conduit under a pressure of 100 to 2500 bar and are mixed to give a solvent mixture. The solvent mixture is sprayed into a container via at least one nozzle which is at a pressure of 100 to 2500 bar and a temperature of 10 to 90°C, said container having a lower pressure.
In a process for extracting products of value from animal or vegetable starting material the intention is to provide a solution with which the extraction is improved in terms both of the yield and the separation of natural products to be extracted and of the process management. This is achieved by extracting soluble constituents from the starting material in a first extraction step with the aid of CO2, and subsequently extracting further constituents in a second extraction step with compressed hydrocarbons.
The invention relates to an extraction method for producing soluble substances from organic plant or animal raw material with high pressure, wherein supercritical gas is used as a solvent and wherein the organic material is filled into one or a plurality of high pressure reservoirs. The high pressure reservoirs are closed and a pressure of more than 800 bar is subsequently applied. In an extraction step, the supercritical gas flows at least once through the filled high pressure reservoir, wherein no additional entraining agent is added to the supercritical gas. Subsequently the charged supercritical gas is fed completely or partially to a separation stage, wherein natural substances or substance mixtures are reacted or separated from each other by lowering the pressure. The pressure in the extraction stage exceeds the maximum solubility pressure of the oil or fat of the raw material in the supercritical gas at least by 10%. The respective oil or fat of the raw material serves as the entraining agent.
