Instrument and process for nanoparticles production in continuous flow mode

A continuous flow device (50) for executing a process of preparation of nanostructures, the device (50) comprising:

• a first feeding unit (1a) with a first feed pump (9) connected to a first raw material source (7);
• a second feeding unit (1b) with a second feed pump (10) connected to a second raw material source (8);
• a first reactor unit (2) with a first reactor-zone unit (13) configured to receive material from the first feeding unit to heat to a given first temperature value and to feed into a first cooling unit (14) comprising a first countercurrent heat-exchanger configured to provide an enhanced rate of heat exchange to decrease particle size of nanostructures being prepared by the device;
• a mixing unit (5) configured to receive an output from the first cooling unit (14) and second raw material from the second feeding unit (1b);
• a second reactor unit (3) with a second reactor-zone unit (15) configured to receive output from the mixing unit (5) and to be heated to a given second temperature value to feed into a second cooling unit (16) comprising a second countercurrent heat-exchanger configured to provide an enhanced rate of heat exchange to decrease particle size of nanostructures being prepared by the device;
• at least one pressure controller (18) arranged in a flow path defined by the first reactor unit (2) and the second reactor unit (3) and configured to set a pressure value in the flow path;
• a control unit (22) configured to control at least one of the pressure value set by the pressure controller (18), the given first temperature value, and the given second temperature value;
• wherein the respective cooling units (14, 16) are configured to terminate the process of preparation of nanostructures.
