A cannabis oil extraction apparatus may include an extraction unit, condenser,winterization unit,micron filter, preheater, short-path distillation unit, and condenser. Theextraction unit mayutilize cellular disruption in a food grade solvent to extract cannabis oilfrom plant material. Theshort-path distillation unit may utilize molecular distillation. The short-path distillation unit mayinclude a recirculation loop for multiple passes through the short-pathdistillation unit to separateextract components by weight. In one example, multiple short-path distillationunits may bealigned is series to incrementally separate extract components by weight.
