Mixed liquid manufacturing apparatus

A mixed liquid manufacturing apparatus comprising:

• an information input unit, in which customer information is input;
• a material storage system that stores a plurality of materials for a mixed liquid;
• a product information system that selects kinds and quantities of the stored materials on the basis of the input customer information;
• a liquid transfer unit, by which the selected materials are taken out from the material storage system;
• a mixing unit, in which the materials supplied from the liquid transfer unit are mixed;
• an injection unit, by which the mixed liquid is injected into a mixed liquid container;
• an input unit, by which matters being declared on a label of the mixed liquid container are input;
• and
• a label formation unit, in which the input matters are printed on the label and the label is stuck on the mixed liquid container, and
• wherein the mixing unit comprises a first substrate and a second substrate that define therebetween a flow passage, through which a fluid flows,
• the first substrate comprises a first nozzle region, in which a plurality of first nozzles for supplying a first fluid being mixed with the fluid flowing through the flow passage are arranged at intervals in a direction transverse to the flow of the fluid flowing through the flow passage, and
• a second nozzle region, which is disposed on a downstream side of the first nozzle region in the flow passage, and in which a plurality of second nozzles for supplying a second fluid being mixed with the fluid flowing through the flow passage are arranged at intervals in the direction transverse to the flow of the fluid flowing through the flow passage,
• the second nozzles are arranged in a region, through which the first fluid supplied by the first nozzles flows, in a region, through which the fluid flows.
