FIELD: process engineering.
SUBSTANCE: invention relates to production of vegetable oils. Method of recovery of waste filtration material obtained in cleaning sunflower-seed oil from wax comprises separation of waste filtration material into recovered filtration material and recovered sunflower-seed oil enriched with waxes. Note here that methylene dichloride is forced through stationary bed of waste filtration material placed on screen with mesh not exceeding 0.15 mm. Note also that material layer temperature and that said methylene dichloride forced there through make, at least, 35°C while subsequent sublimation of residual methylene dichloride is carried out at material moisture content of, at least, 5 wt %.
EFFECT: production of valuable products, ie recovered filtration material, recovered sunflower-seed oil enriched with waxes.
