A processing device and processing method that can perform processing of a starting material fluid while favorably controlling the processing temperature of same. The processing device includes: a processing member that leads in the starting material fluid and processes same therewithin; and a processing tank that houses the processing member and retains the processed processing products. The processing member includes: a minute duct provided therewithin and causes the flow-through of the starting material fluid; and a heat medium duct that causes the flow-through of a heat medium having a different temperature from that of the starting material fluid flowing through the minute duct. The minute duct and the heat medium duct are separated from each other so that heat exchange is possible between the starting material fluid and heat medium flowing through.

The flow passage structure comprises: a plural number of ceramic flow passage layers laminated with one another, inside of which a flow passage is formed; two outermost layers disposed on respective sides of the plural number of flow passage layers in a lamination direction where the flow passage layers are laminated; an outer elastic sheets made of an elastic body, which is interposed between each of the outermost layers and the flow passage layer adjacent thereto; and a fastening member fastening the two outermost layers to each other, in a state that the two outermost layers sandwich the flow passage layers from both sides in the lamination direction.

Disclosed herein is a method for designing a liquid-liquid biphasic micro-fluidic flow channel reactor for continuous extraction or reactive extraction, where chemistry happens in one phase and the product is removed to the other. The method comprises developing random forest and symbolic genetic regression machine learning (ML) models to predict flow patterns and the mass transfer rate, respectively, using a combination of experimental and computational fluid dynamics (CFD) data and literature-mined data while accounting for the effects of solvent properties and channel diameter. This enables rapid prediction for efficient scale-up of microchannels to millichannels. To minimize the number of CFD simulations and maximize model accuracy, the method comprises using active learning techniques.
