Abstract
A micromixer, a sorter device, and a method for manufacturing fiber are provided. The micromixer includes a first portion configured to provide a first flow passage, and a second portion configured to provide a second flow passage branched from a middle of the first flow passage, wherein an inner wall of the second flow passage has a spiral shape along a longitudinal direction of the second portion.
Claims11
A micromixer comprising:
- a first portion configured to provide a first flow passage;
- and
- a second portion configured to provide a second flow passage branched from a middle of the first flow passage, wherein
- an inner wall of the second flow passage has a spiral shape along a longitudinal direction of the second portion.

A sorter device comprising:
- a fiber provided with a spiral flow passage;
- and
- a separator communicating with the spiral flow passage and including a first flow passage and a second flow passage, a component on an outer side of the spiral flow passage flowing into the first flow passage, a component on an inner side of the spiral flow passage flowing into the second flow passage.
A method for manufacturing a fiber, the method comprising:
- forming a preform including a through hole and having a rod shape;
- and
- forming a fiber by hot drawing the preform in one direction while the preform is rotated, wherein
- a polymeric material is applied to the through hole of the preform, and
- the through hole having a spiral shape is obtained by dissolving the polymeric material after the hot drawing.
