The gas is transported to the inside of the vacuum pump 13 through the connecting tube 15 and the delivery pipe 14, and then discharged through the vacuum pump 13. The operation is continued during the mixing process, so that the foam inside the mixing drum 3 gradually disappears, and the gas in the raw materials is also extracted, thereby achieving a degassing effect.
