The present invention describes a method and an automatic system for recovering protein powder meal, crude and pure omega-3 oil and purified distilled water from a mixture of animal tissue processed in a filter-drier-reaction tank. Animal tissue, for example fish, and organic solvent are directly or indirectly fed into the filter-drier-reaction tank. The filter-drier-reaction tank mixes, heats, and separates solid and heavy liquid portions of the mixture, the organic solvents are automatically recycled back in to the system after distillation. The solid portion is retained in the filter-drier-reaction tank and baked. Solid protein powder product (the protein powder meal) is thus recovered.
