PROBLEM TO BE SOLVED: To provide a method and a system for producing a uniform filler-mixed devolatalized silicone composition by efficiently compounding a high-level inorganic filler, a machining fluid, and a silicone polymer at a commercial rate. SOLUTION: A first dispersion composition is manufactured by compounding the filler, the machining fluid, and the silicone polymer by means of a first compounding device 12; and concurrently, a second dispersion composition is manufactured by compounding the filler, the machining fluid, and the silicone polymer by means of a second compounding device 14 by sharing the same extruder shaft 16 with the first compounding device. An extruder transition section 18 of this system is equipped with a sealed ejection chamber 20 which is defined by a lower wall with a proper contour shifting toward a first partition wall 26, a second partition wall 28 and an ejection port 24; and the shaft 16 passes through the first partition wall 26, extends across the ejection chamber 20, and passes through the second partition wall 28.
