Process for producing raw juice for making sugar, process for making sugar, and sugar-production installation

Abstract

The present invention relates to a process for producing raw juice (14) for the production of sugar, wherein sugar beet pulp (11) is fed to an extraction device (20), for example an extraction tower or a diffusion trough, and sugar beet pulp residues (13) and raw juice (14) are withdrawn from the extraction device (20), wherein a first near-infrared spectroscopy device (21) is used to detect first measurement data relating to the sugar beet pulp (11) which is fed to the extraction device (20), and/or a second near-infrared spectroscopy device (22) is used to detect second measurement data relating to the sugar beet pulp residues (13) which are withdrawn from the extraction device (20), and/or a third near-infrared spectroscopy device (23) is used to detect third measurement data relating to the raw juice (14) that is withdrawn from the extraction device (20). The invention further relates to a sugar production plant and a process for producing sugar, wherein raw juice (14) is produced and sugar is produced from the raw juice (14) in subsequent process steps.
