PURPOSE:To provide a kneader which is so constituted as to segment fluids efficiently to multiple layers by providing partition walls which divide the inside of a layering pipe into two narrow branch flow passages and one wide branch flow passages in the longitudinal direction of said pipe and changing the sectional shapes of the branch flow passages along the flow passages. CONSTITUTION:Partition walls 7, 8 which divide the inside of a layering pipe 4 into three layers longitudinally have two arc-shaped sections which face with each other in the inlet part, and have a T-shaped section in the outlet part, which sections change smoothly from the inlet part toward the outlet part. The sectional area ratio of the two narrow branch flow passages 5, 5 and one wide branch flow passage 6 formed by a partition wall 6 are so set as to maintain roughly 1:1:2 ratios at all times over the entire length. Thw two confluent fluids R1, R2 flow in the state of two layers into the respective passages 5, 6, and form separating interfaces K1, K2 respectively. The separated fluids join together in the outlet parts, and the fluids consisting of four layers R1, R2, R1, R2 are obtained. |
