PROBLEM TO BE SOLVED : To provide a purifying apparatus of an organic material, which is entirely cleared of recovery loss of deposited organic materials and can extremely increase an operating efficiency of the organic materials.
SOLUTION : The purifying apparatus of the organic material sublimating the organic material M and increasing the purity consists of a vessel for sublimation 22 enabling an evacuation, having a gas inlet 40 at one end and a gas outlet 42 at the other end, and having a first support and a second support separated by a predetermined distance inside, a holding container 24 containing the organic material set in the first support, a first heating means 26 heating the holding container to the sublimation temperature or more of the organic material, a plurality of detachable recovery blocks 28A-28C set in the second support and recovering the re-solidified organic material, and a second heating means 30 heating so as to provide a temperature gradient only in the sector wherein a plurality of recovery blocks are arranged. The first support enables the setting of also the recovery blocks to which the organic material having the highest purity among a plurality of the recovery blocks is deposited. |
