Abstract
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.
