Abstract
The problem addressed by the present invention is providing a fluid processing method including extraction that can extract material to be extracted continuously with high efficiency. In a thin film fluid formed between at least two processing surfaces (1, 2) disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other, a fluid processing that extracts at least one kind of material to be extracted in at least one kind of the extraction solvent that can extract that material to be extracted is carried out. In addition, the fluid containing at least one kind of material to be extracted and a fluid for extraction that contains the at least one kind of extraction solvent are mixed in the thin film fluid formed between the at least two processing surfaces (1, 2) disposed facing each other so as to be able to approach to and separate from each other such that at least one rotates relative to the other, and a fluid processing process that extracts the at least one kind of material to be extracted into the at least one kind of extraction solvent is carried out.
