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: An object conveying system is provided. The system comprises guide plate (10) having at least one channel (11) for conveying an object (0) between a first end (11a) and second end (11b) of the corresponding channel (11). Each channel (11) comprises a first aperture (121) provided at a first longitudinal position thereof (P1).The system further comprises an object measurement unit (13) for conducting an optical measurement associated with a property of the object via the first aperture (121) when the object passes the first aperture (121) towards the second end (11b). At least one ejector unit (14) is arranged to eject the object conveyed on the corresponding channel when reaching a second longitudinal position (P2, P2?) located downstream of the first aperture (121) based on the measured property of the object and a timing signal associated with a conveying velocity of the object being conveyed along the channel (11).

Abstract: A detector system (100) comprising a plurality of light guides (11a, 11b, 11c, 11d) is provided. Each light guide (11a, 11b, 11c, 11d) is guiding incoming light from a respective object in use, wherein the incoming light is provided by means of an illuminating means (10). The detector system (100) comprises diffracting means (12) for diffracting the incoming light in different wavelength ranges, at least one focuser (13) for projecting the incoming light exiting the light guides onto the diffracting means, a detector (14) having a detector area for receiving the diffracted light from the plurality of Sight guides, and a control unit (15). 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 (14) 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.
