<p>PURPOSE:To reduce the volume of a setter to shorten extraction time and, obtain an extractor with high extraction efficiency by forming a porous wall of porous material in a partition between a mixer room and a settler room. CONSTITUTION:A mixer settler extractor with a porous wall 1 is composed of a mixer room 2, a settler room 3 and a porous material layer 4 which is arranged between both rooms and filled with, for instance, cubic particles of less than 1cm diameter in a laminar form. A stirrer 5 is provided in the mixer room 2. Subsequently, the residence time of an extract liquid in an extractor 1 becomes short by reduction of the volume of the settler room 3. Thus a continuous multi-stage extractor is operated efficiently.</p> |
