Abstract
A pretreatment for use with systems and methods for extracting and separating a bio-molecule, such as a lipid and/or a protein, from a biomass includes the step of contacting the biomass with a drying gas to substantially dewater the biomass to 20% water content by mass or less. Such pretreated biomass, mixed with one or more compressed liquefied gas solvents, may then be introduced into individual filter cells in a rotary pressure filter to separate lipids from proteins.
