The 5lb Bi-Directional closed loop increases efficiency by utilizing both a bottom and top solvent input. It uses a bottom flood on the first wash to ensure all material has seen solvent, preventing channeling through the material. Finish the run with a top flood input to ensure all residuals have been washed from the material. Oil-bearing solvent is collected in the collection base under the material column. Once collected, the solvent is distilled and recovered, leaving the oils in the collection base. This is a passive unit that utilizes pressure differences created by manipulating temperature to move solvent.
