1. A POD cleaning process comprising:
separating a POD into separated POD components comprising an inner POD and an outer POD;
cleaning the separated POD components within a plurality of cleaning sub-chambers;
using a chamber moving mechanism for transforming the separated POD components from the cleaning sub-chamber to a drying chamber;
drying the separated POD components, which undergoes the cleaning, within the drying chamber;
vacuum-processing the separated POD components undergoing the drying; and
assembling the inner POD and the outer POD that undergo the vacuum processing into an assembled POD,
wherein the cleaning and the drying are separately performed;
wherein the cleaning sub-chamber comprises:
a first cleaning nozzle injecting cleaning solution to clean the separated POD components entirely;
a second cleaning nozzle injecting steam to clean the separated POD components entirely;
a set of first drying nozzles arranged on both sides of the POD toward the separated POD components and drying the cleaning solution by injecting gas; and
a first air knife arranged adjacent to an exit of the cleaning sub-chamber and blowing the cleaning solution remaining on entire surfaces of the separated POD components by injecting gas at an angle inclined with respect to a surface of one of the separated POD components;
wherein the drying chamber comprises:
a set of second drying nozzles arranged on both sides toward the separated POD components and injecting dry gas;
an infrared (IR) lamp emitting infrared light thereby drying the separated POD components, and
a second air knife arranged in the drying chamber, respectively, and injecting gas at an angle inclined with respect to a surface of one of the separated POD components,
wherein the chamber moving mechanism comprises:
a jig on which the separated POD components are stably mounted and a moving unit coupled to the jig to move the jig; and
wherein the moving unit is arranged outside the cleaning sub-chamber and the drying chamber;
wherein the jig comprises a holding portion for supporting the separated POD components and a coupling portion for connecting the holding portion to the moving unit;
wherein the holding portion comprises:
a first portion coupled to the coupling portion downwardly at a right angle,
a second portion extending from an end of the first portion at an inclination and coupled to the separated POD components, and
support pins coupled to the second portion and arranged on a lower portion of the second portion to support a lower portion of the separated POD components, and arranged on side surfaces of a frame of the second portion to support both side surfaces of the separated POD components,
wherein the second portion has a rectangular cross-section having a greater size than an external edge of the separated POD components so that the second portion is exposed to both lateral sides of the separation POD.
