Abstract
A portable machine for sanitizing soil, particularly that contaminated with petroleum products, including a closed main chamber including vertically spaced augers (26,28,30) which agitate the soil while moving it into position to fall in parallel sheets after it strikes a separation bar 52. A burner 44 generates heat which passes through the falling soil driving off the petroleum which is then burned.
