1. A system comprising:
a source of a latex containing an unreacted monomer; and
a post-processing apparatus fluidly connected to the source of latex and configured to receive the latex and reduce a content of the unreacted monomer in the latex,
wherein the post-processing apparatus comprising:
a receiving tank having therein: a receiving part; an inlet port through which the latex is introduced into the receiving part; and a discharge port through which the latex is discharged;
an ultrasonic wave generating device configured to generate ultrasonic waves to the latex accommodated in the receiving tank;
a pressure reducing part configured to reduce a pressure of the receiving part of the receiving tank to discharge the unreacted monomer to outside of the receiving tank;
a partition part provided in the receiving part of the receiving tank and comprising a plurality of partitions disposed in a direction from the inlet port toward the discharge port of the receiving tank; and
temperature adjusting parts positioned in the receiving part of the receiving tank and configured to adjust a temperature of the latex accommodated in the receiving part, wherein the latex accommodated in the receiving part moves along upper and lower sides of the plurality of partitions,
wherein the plurality of partition comprise:
lower partitions fixed to a bottom surface of the receiving tank; and
upper partitions positioned to be spaced apart upward from the bottom surface of the receiving tank at a predetermined interval, and
wherein each of the temperature adjusting parts is disposed between the lower partitions and the upper partitions in a movement direction of the latex, except for one of the temperature adjusting parts which is closest to the inlet port and one of the temperature adjusting parts which is closest to the discharge port.
