A root crop conveyor is provided for cleaning and/or separating root crops, including at least two adjacent roller groups, each of which have at least two rollers, which each rotate about an axis of rotation and of which the axes of rotation form a roller group plane. An adjusting device is provided with at least one adjusting means. At least the rollers of at least one roller group are mounted, on one side, in at least one side part which interacts with the adjusting means, such that actuation of the adjusting means can give rise to movement of the at least one roller group plane relative to a frame in which the root crop conveyor can be arranged. wherein the adjusting device pivots the roller group plane. The rollers of a roller group are connected to one another via a scissors mechanism.

Methods and apparatus for washing food products are provided. An example controller for controlling washing of a food product is generally configured to execute executable instructions to cause the controller to control generation of a silver ion solution in a wash stage, the generation including mixing components of the silver ion solution in the wash stage, and to control application of the silver ion solution to the food product in the wash stage. An example method of washing a food product generally includes generating a silver ion solution in a wash stage, the generating including mixing components of the silver ion solution in the wash stage, and applying the silver ion solution to the food product in the wash stage.

Methods and apparatus for washing food products (e.g., round produce) are provided. An example apparatus for washing at least one item of round produce generally includes: an applicator configured to apply a first wash treatment solution to an entire exterior surface of the at least one item of round produce; and an opaque shroud configured to prevent light from impinging on the at least one item of round produce and the first wash treatment solution.
