    • A centering device is provided for centering a potato with respect to a propelling hydraulic fluid flow stream which carries the potato into cutting engagement with knife elements of a cutting assembly positioned along the flow stream. The device comprises an elongated tube at the upstream end of the cutting assembly shaped to define a linear flow path of generally circular cross-section and oriented for continuously accelerating the hydraulic fluid. This acceleration results in the fluid having a slightly higher velocity than the potato throughout the length of the tube to create, when the potato is displaced from a centered position, fluid velocity and pressure differentials on opposite sides of the potato tending to return the potato to the centered position.
    • 提供了一种定心装置,用于相对于推进的液压流体流将马铃薯定中心,该流动流将马铃薯与沿着流动流定位的切割组件的刀元件切割接合。 该装置包括在切割组件的上游端处的细长管,其被成形为限定大致圆形横截面的线性流动路径并且被定向成用于连续加速液压流体。 这种加速度导致流体在管的整个长度上具有略高于马铃薯的速度,当马铃薯从中心位置移位时,马铃薯的相对侧上的流体速度和压力差趋于将马铃薯返回到 中心位置。
