Abstract
This process consists in degreasing a plurality of objects (15) with the aid of a degreasing liquid, each object having a surface coated with a layer of fat. The degreasing liquid employed has a higher adhesion tension to the surface of each object than has the fat and it is practically immiscible or only partially miscible with the fat. The operation of degreasing consists in covering the layer of fat with said liquid in order to lift the fat off and suspend it in said liquid; separating the object from the suspension; collecting said suspension in order to separate it into two phases; and recycling the phase (5, 8) consisting essentially of the degreasing liquid. <IMAGE>
