Abstract: A method is disclosed for sorting a plurality of objects including an object that is one of a grain, a nut, a tree nut, or a bean. The plurality objects are conveyed along a guide plate having at least two channels between a first end and a second end of the corresponding channel. The channels have a first aperture provided at a first longitudinal position thereof and an additional aperture provided at a second longitudinal position on the guide plate located downstream of the first aperture. An optical measurement associated with a property of the object of the plurality of objects is conducted when the object passes the first aperture towards the second end with an object measurement unit. The object conveyed on the corresponding channel is ejected with an ejector unit when reaching the second longitudinal position based on the measured property of the object and a timing signal.

Abstract: A detector system is disclosed herein that includes a plurality of light guides. Each light guide is guiding incoming light from a respective object in use, wherein the incoming light is provided by means of an illuminating means. The detector system comprises diffracting means for diffracting the incoming light in different wavelength ranges, at least one focuser for projecting the incoming light exiting the light guides onto the diffracting means, a detector having a detector area for receiving the diffracted light from the plurality of Sight guides, and a control unit. These are arranged to pulsate incoming light via only one light guide at a time based on a pulse timing parameter, and record a spectrum of light diffracted from each light guide and detected by the detector based on the pulse timing parameter.

Abstract: A drum (100) for sorting objects is provided. The drum has a cylindrical shape, and said drum (100) comprises a cylindrical body (101), with an inner and an outer envelope surface. A plurality of pockets (104) are arranged on the inner envelope surface of the cylindrical body (101), and said pockets (104) are provided with openings (105) opening up into the outer envelope surface. At least one groove (106) is arranged on the outer envelope surface, said groove (105) interconnecting at least two openings (105). A machine (1000) comprising such a drum (100) and a method for manufacturing such drum (100) are also provided.

Abstract: A sorting device to sort granules within a bulk of granules, where the granules differ in quality includes a positioning means giving a well-separated position for each granule. At least one detector is arranged to receive electromagnetic radiation or sonic waves sent by an energy source via the granules. Furthermore, ejecting means are arranged to eject the granules into receiving means based on the detected quality.

Abstract: A method of sorting sorting objects within a bulk of objects from a heterogeneous population is provided. The bulk of objects to be sorted has an inherent variation, and at least one class, having less variation than the originally inherent variation of the bulk, is separated from the bulk. This lesser variation represents a quality of composition with reference to any organic material of the objects within the bulk.
