An evacuator for a plastic bag containing viscous liquid within a rectangular, parallelepiped container having a drain positioned at a bottom edge region uses a windlass for drawing and winding an evacuated upper region of the bag to a region above the drain. A bag wall region diagonally opposite the drain is gripped, preferably with a noose; and a windlass positioned on the walls of the container above the drain draws the gripped region of the bag across the top of the container and then winds the evacuated upper regions of the bag onto the windlass to funnel the viscous liquid toward the drain in lower, unevacuated regions of the bag.
