PROCESSING DEVICE AND PROCESSING METHOD

摘要

Provided are a processing device (1) and a processing method that enable an efficient chemical operation by means of reducing the time for separating into individual starting material fluids a mixture of starting material fluids that had once been fractionated. The processing device (1) is provided with: a separation tank (5) that contacts together a first and second starting material fluid (2a, 2b) that differ in specific gravity, performing a chemical operation at the portion at which both starting material fluids contact, and houses the first and second starting material fluids (2a, 2b) that are separated vertically; and a flow path forming member (6) that is disposed within the separation tank (5) and forms a plurality of minute ducts (7) for causing the upper starting material fluid (2a) layer to contact the lower starting material fluid (2b) layer. Each minute duct (7) is provided with: a first duct (9) that penetrates the flow path forming member (6) in the vertical direction and guides the second starting material fluid (2b) below the flow path forming member (6) to above the flow path forming member (6); and a second duct (10) that connects to the first duct (9) in a manner so as to introduce the upper first starting fluid (2a) layer into the first duct (9).
