    摘要: An oriented flow extraction method, apparatus, and extract are disclosed. The oriented flow extraction method can comprise loading extraction material into an extraction cell having a first portion and a second portion; introducing a first aliquot of extraction medium through the first portion of the extraction cell; expelling gas from the extraction cell through the second portion of the extraction cell; closing the second portion of the extraction cell and increasing the pressure in the extraction cell as extraction medium flows into the first portion of the extraction cell; stopping the flow of extraction medium into the extraction cell; steeping the extraction material in the extraction medium under pressure to produce an extract; and introducing a second aliquot of extraction medium through the first portion of the extraction cell to push extract through second portion of the extraction cell. In some embodiments, the first portion is a bottom portion and the second portion is a top portion of the extraction cell.
