摘要
PURPOSE: A method for extracting and separating high purity fat and fatty oil from waste edible oil with a high efficiency is provided. A combined extracting and separating device for fat and fatty oil is also provided. CONSTITUTION: The method for extracting fat and fatty oil from waste edible oil by using a supercritical fluid is characterized in that a combined extracting and separating device(100) for fat and fatty oil having a single structure is used to carry out the extraction and phase separation after the extraction at the same time. Preferably, the supercritical fluid is CO2. The device(100) comprises an upper nozzle(1) which performs a tangential projection of the waste edible oil to convert them into fine oil particles and a lower nozzle(2) which performs a tangential projection of the supercritical fluid to carry out counter-current extraction so that the contact time and area between the oil and the fluid can be maximized.
