The invention relates to a method of extracting useful compounds from vegetable matter, and firstly includes preparing a mixture of vegetable matter and at least one solvent, thereafter allowing the mixture of vegetable matter and solvent to reside in at least one vessel for a substantially predetermined period of time. The vegetable matter can for example be coffee beans, or bark. After the mixture has resided in the vessel for the desired predetermined time, the mixture is separated into a solvent phase and a vegetable phase by means of a suitable screen, the mixture firstly being transferred from the vessel to the screen, and being formed as a mat or cake on the screen. The solvent phase is recovered from the mat or cake formed on the screen, and useful compounds are extracted from the vegetable matter of the mat or cake, as a filtrate from said screen. |
