PERDAS INDUSTRIAIS NA RECEPÇÃO, PREPARO E MOAGEM DA CANA NO SETOR SUCROENERGÉTICO

Abstract

n the sugar-energy industry, losses are called determined and indeterminate and can be divided between: physical, chemical and microbiological losses, resulting from the following factors: poor quality raw material; inadequate conduct of the process, layout, equipment, work team and lack of supervision. Industrial losses cause major economic problems when not properly managed. This work is a case study carried out at Usina Monte Alegre, during the 2020/21 harvest, which aimed to quantify and evaluate the losses determined in the process of receiving, preparing and milling sugarcane. The work was carried out by collecting data on the technological parameters of sugarcane, from strategic points, such as: cane in the field, receiving, preparing and crushing the cane. The sucrose losses were calculated through the percentage variation between the evaluated technological parameters. Through the study carried out it was possible to perceive, in the analyzed weeks, a negative percentage variation of purity, meaning the decrease of purity between the analyzed stages, as well as the evidence of greater losses that occurred between the cane at the entrance and the cane on the conveyor, in weeks 9 and 14, these losses were evidenced through the reduction of the percentage variation of purity and the increase of the percentage variation of the AR, whereas the data collected from the residual bagasse showed a stability of the analyzed parameters.
