A system for conveying a substrate includes a noncontact support platform for supporting the substrate. A vacuum wheel is located adjacent to the support platform. A rim of the vacuum wheel includes perforations that open between an exterior of the rim and an interior of the vacuum wheel. A fixed suction surface is interior to the vacuum wheel and includes an opening of a conduit that is connectable to a suction source. A chamber is formed by the suction surface, walls of the vacuum wheel, and a section of the peripheral rim that is adjacent to the suction surface and that extends outward from the support platform. When suction is applied to the conduit, the suction is applied via the chamber to the perforations in the rim section so as to exert a pull on the substrate toward the rim such that rotation of the vacuum wheel conveys the substrate.

A method for the partial emptying of buoyant objects, which are stored in a loading aid having at least one opening is provided. A processing weight to be partially emptied is established. A fill weight is determined of the objects in the loading aid via a first weighing. The loading aid is at least partially immersed in a liquid bath. The loading aid is positioned or moved for a retention time predefined as a function of the fill weight and of the processing weight in the bath such that there is an on-average constant flow relative to the loading aid and such that the opening is disposed at least partially below a fill level surface of the bath, whereby the objects are taken along by the flow. The at least partially emptied loading aid is lifted out of the bath after the retention time has elapsed.

A unit for transferring horticultural products between at least one tank, in which the horticultural products float on a fluid mass, and at least one collection container, including a head provided with a plurality of walls normally arranged vertically. The head is movable between at least one collection position, in which the walls are interposed between respective horticultural products, which float on the fluid mass at a respective predefined section of the tank, and at least one unloading position, in which the walls face and are proximate to the collection container. In an active configuration, the transverse elements protrude transversely from the space occupation of the walls to ensure mechanical interference with the fall of the horticultural products as a consequence of the subsequent lifting of the head and of its transfer toward said unloading position.
