Systems and methods are provided for processing seeds collected from a field. One example system includes a trailer supporting a hopper configured to hold seeds to be devitalized, a mill configured to devitalize the seeds held in the hopper, and a spreader configured to discharge the devitalized seeds from the system. A first transport assembly interconnects the hopper and the mill, on the trailer, to transport the seeds from the hopper to the mill. And, a second transport assembly interconnects the mill and the spreader, on the trailer, to transport the devitalized seeds from the mill to the spreader.

Seed crushing device comprising a receiving space for a seed grain, defined by one or more side walls, designed to be positioned in at least a first position, where the receiving space is freely accessible from its top side for placing the seed grain in the receiving space; and where the receiving space at its bottom is closed to support a seed grain that has been placed, and a second position, where the receiving space is freely accessible from its top side to accommodate a pestle in the receiving space, and where the receiving space at the bottom is closed for crushing the seed grain by pushing the pestle towards the bottom and for supporting the flower thus formed; and a third position, where the receiving space is free at least the bottom for discharging the flower in a filling position from a deep well plate.

A method of crushing and processing grain without destroying germ pouches in the grain, by: (a) crushing grain in the primary single-pass crushing machine, and then sieving the grain to sort the grain into two or more particle sizes; (b) transporting larger sized particles from the sieved grain into a secondary single-pass crushing machine; (c) crushing the larger sized particles of grain in the secondary single-pass crushing machine; (d) sieving the grain crushed in the secondary single-pass crushing machine to sort the grain into two or more particle sizes; and then (e) combining smaller sized particles sieved from the primary single-pass crushing machine with smaller sized particles sieved from the secondary single-pass crushing machine.

A rock processing apparatus is provided for crushing and/or sorting granular mineral material according to size. The rock processing apparatus comprises a material feeding apparatus including a material buffer, at least one working unit of at least one crushing apparatus and at least one screening apparatus, at least one conveyor apparatus for conveying material between two apparatus components, a control unit for controlling apparatus components, at least one sensor for detecting at least one operating parameter, the sensor being connected to the control unit for transmitting a detection signal, at least one output device for outputting information and connected to the control unit. The control unit is designed to ascertain, in an operation with discontinuous material feed, and based on the at least one detection signal, time information about a future material feed, wherein the output device is designed to output the ascertained time information.
