The utility model belongs to the technical field of the splitter, particularly, involve a chromatographic column that is used for jiangxi south mountain tea -seed oil to decolour. It is including straight section of thick bamboo portion and pars infundibularis, straight section of thick bamboo portion is bilayer structure, and its inlayer bottom is equipped with ceramic sieve, pars infundibularis upper end detachablely with the straight sealing connection of section of thick bamboo portion, its lower extreme connects gradually piston and play oil pipe, go out middle being equipped with of oil pipe and open up wide section, should open up the upper right side of wide section and be equipped with the exhaust tube, pressure relief device is connected to the exhaust tube, is equipped with the filtration membrane of ventilative oil -tight in it. Compared with the prior art, a chromatographic column that is used for jiangxi south mountain tea -seed oil to decolour include bilayer structure, the inlayer is used for filling the adsorbent, the skin is used for filling hot water to play the heating centrifugation, simultaneously, open up wide section with establishing on an oil pipe for the decompression operation is because filtration membrane's effect can guarantee that oil is not taken away when the decompression.
