Abstract (en)
[origin: WO8503721A1] The process of simultaneously defatting and dehydrating raw fat animal tissue and other tissues in comminuted form by introducing the tissue particles into a boiling alcohol solvent, the fat of the tissue and water of the tissue being extracted into the body of boiling alcohol to form a slurry of alcohol, particles, fat and water. The water of the tissue and alcohol in an azeotropic vapor form are distilled off from the body of slurry and separated in a subsequent distillation to recover the alcohol for recycling. When sufficient water is removed from the slurry, the solids are separated from the liquids of the slurry, and the alcohol is evaporated from the fat. The recovered alcohol is dehydrated to less than 5% water by volume, and returned to the mass of alcohol. In addition to the process, the invention covers apparatus for carrying out the foregoing process.
