Abstract
A centrifugal pea embryo skin separator was designed, and its separation mechanism was also analyzed. The embryo skin did the circular motion under the action of the friction force when it entered the high-speed rotating disk and was thrown out by overcoming the friction force.Due to the different apparent density between the bean embryo and skin, the larger apparent density of the bean embryo was throwninto the outside received barrel, and the smaller apparent density of the bean skin was fallen into the inside received barrel. So chang the height of the received barrel relative to the separation disc can alter the ratio of the bean embryo to the bean skin to adapt to the different enterprises requirements. This paper gave the detailed analysis and calculation of the seperator mechanism, and established the mathematical model of the absolute speed va, angular velocity ω and the exit radius r,. So it canprovide references for the subsequent development work.
